    Playing active video games can produce moderate levels of physical activity, but little is known about how these games motivate players to be active. Several psychological predictors, such as perceptions of competence, control, and engagement, may be associated with enjoyment of a game, which has in turn been hypothesized to predict energy expended during play. However, these relationships have yet to be tested in active video games. Young adults aged 18-35 (N = 97, 50 female) game for 13 minutes while energy expenditure was measured using indirect calorimetry. Self-reported measures of engagement, perceived competence, perceived control, and enjoyment were taken immediately afterward. Mediation was analyzed using path analysis. A path model in which enjoyment mediated the effects of engagement, perceived competence, and perceived control on energy expenditure and BMI directly affected energy expenditure was an adequate fit to the data, χ(2)(1, N = 97) = .199, p = .655; CFI = 1.00; RMSEA video game play. Games that are more enjoyable and engaging may produce greater intensity activity. Developers, practitioners, and researchers should consider characteristics that influence these predictors when creating or recommending active video games.

    Federal guidelines state that youth should participate in a variety of physical activity (PA) they find enjoyable. Little is known, however, about how variety and enjoyment are associated with PA participation among adolescents. Data came from the 2010 National Youth Physical Activity and Nutrition Survey, a nationally representative survey of adolescents. Path analysis was used to examine the association of a variety of self-reported PA, defined as the number of activities and activity types (ie, team sports/weightlifting, individual activities, and other competitive/recreational sports), on self-reported PA enjoyment and participation. The analysis also examined whether enjoyment mediates the association between a variety of PA and participation. Separate models were estimated for boys and girls. Number of activities was associated with increased PA enjoyment and participation. For boys and girls, team sports/weightlifting was associated with increased participation, and individual activities were indirectly associated with increased participation through enjoyment. For boys, team sports/weightlifting was indirectly related with participation. These findings suggest that participation in a variety of PA is associated with increased PA enjoyment and participation. Providing opportunities for adolescents to engage in a variety of activities might help them identify PA they enjoy and facilitate lifelong PA habits.

    Whereas prior literature has studied the positive effects of curiosity-evoking events that are integral to focal activities, we explore whether and how a curiosity-evoking event that is incidental to a focal activity induces negative outcomes for enjoyment. Four experiments and 1 field study demonstrate that curiosity about an event that is incidental to an activity in which individuals are engaged, significantly affects enjoyment of a concurrent activity. The reason why is that curiosity diverts attention away from the concurrent activity and focuses attention on the curiosity-evoking event. Thus, curiosity regarding an incidental event decreases enjoyment of a positive focal activity but increases enjoyment of a negative focal activity.

    Full Text Available The purpose of this study was to analyze motivational profiles based on the self-determination theory (Deci and Ryan, 2000 and how these profiles are related to physical education students' enjoyment, state anxiety, and physical activity. The participants, 429 sixth grade students (girls = 216; boys = 213 completed SMS, Sport Enjoyment Scale, PESAS, and Physical Activity Scale. Cluster analyses identified two motivational profiles: 1 the "High motivation profile", in which the students had high intrinsic and extrinsic motivation, and low levels of amotivation, and 2 the "Low motivation profile", in which the students had low intrinsic and extrinsic motivation, and low levels of amotivation. The students in the first cluster enjoyed physical education more and were physically more active. The results revealed that students may be motivated towards physical education lessons both intrinsically and extrinsically, and still experience enjoyment in physical education.

    Objective To examine whether engaging in multiple enjoyable activities was associated with better psychological and physiological functioning. Few studies have examined the health benefits of the enjoyable activities that individuals participate in voluntarily in their free time. Method Participants from four different studies (n = 1399 total, 74% female, age = 19–89 years) completed a self-report measure (Pittsburgh Enjoyable Activities Test (PEAT)) assessing their participation in ten different types of leisure activities as well as measures assessing positive and negative psychosocial states. Resting blood pressure, cortisol (over 2 days), body mass index, waist circumference, and perceived physiological functioning were assessed. Results Higher PEAT scores were associated with lower blood pressure, total cortisol, waist circumference, and body mass index, and perceptions of better physical function. These associations withstood controlling for demographic measures. The PEAT was correlated with higher levels of positive psychosocial states and lower levels of depression and negative affect. Conclusion Enjoyable leisure activities, taken in the aggregate, are associated with psychosocial and physical measures relevant for health and well-being. Future studies should determine the extent that these behaviors in the aggregate are useful predictors of disease and other health outcomes. PMID:19592515

    Girls' (9-19 years) participation in physical activity (PA) is known to decrease at a faster rate than boys. A reduction in PA attractiveness (enjoyment) and lower psychosocial profile of girls approaching biological maturity may underlie the decreasing rate of PA participation. Since engaging children in active play programs improves health related quality of life indictors and enjoyment levels; the purposes of this study were to: 1) assess psychosocial status and PA attractiveness/enjoyment of boys and girls to an eight-week active play program; and 2) investigate the relationships among PA participation, psychosocial status and PA attractiveness with both age and maturity status for boys and girls following an active play PA program. Thirty-three children (age 9.8±1.3 years; weight 43.1±13.4 kg; BMI 20.8±3.2 kg/m2) were recruited to participate in an active play program for 8 weeks (4x/week; 1hr/d). M-S estimates ranged from -6.7 to -2.5 years away from biological maturity Daily program PA was assessed and compared to pre-post measures of psychosocial functioning and PA attractiveness. Statistical procedures were performed using ANOVA and/or Pearson's correlation r (SPSS v. 22.0) with P=0.05. PA participation in the active play program showed a group average of 39±11% time spent in moderate-vigorous PA (%MVPA) with boys averaging 45% MVPA and girls averaging 30% MVPA (Pattractiveness scores for boys did not change following the program; whereas girls improved from 67±13% to 76±9% (Pattractiveness to %MVPA, 80% of girls reporting positive changes or no change; in contrast 56% of boys responded with negative/less PA attractiveness. PA attractiveness for all children was negatively associated with age (r=-0.19) and/or M-S (r=-0.29). The relationships, however, were gender specific with boys exhibiting a coefficient of -0.28 (age) and -0.61 (M-S) (Pattractiveness promoted less decline in %MVPA for M-S (r=0.18) compared to age (r=-0.17).

    Objective Self-efficacy and physical activity (PA) enjoyment are related to PA behavior, but it is unclear which is more important and how they interrelate. The purpose of this study was to examine how these two constructs interrelate to influence PA behavior. Design Participants were low active adults (n=448) participating in a RCT examining the effect of a PA promotion intervention. Participants completed physical activity, enjoyment, and self-efficacy measures at baseline, six, and 12 months. Results Self-efficacy and enjoyment at both baseline and six months predicted PA at 12 months. However, enjoyment was a stronger predictor than self-efficacy in that self-efficacy no longer predicted PA behavior when included alongside enjoyment. In follow-up mediation analyses, enjoyment at six months did not mediate the effect of baseline self-efficacy on 12-month PA; however, six-month self-efficacy mediated the effect of baseline enjoyment on 12-month PA. Conclusion Our results indicate that interventions should perhaps initially focus on increasing enjoyment of physical activity. Greater PA enjoyment appears to influence individuals’ self-reported ability to engage in regular PA (i.e., higher self-efficacy ratings). Additional research is needed to better understand the interrelationships between self-efficacy and enjoyment and how these constructs affect PA. PMID:26541890

    In this study, we examined the effect of the manipulation of exercise self-efficacy on the enjoyment of physical activity in a sample of 44 Chinese adolescents (age = 14.27 ± .87 y), including 22 boys and 22 girls. The participants were randomized into a low-efficacy or high-efficacy condition, and their self-efficacy beliefs for engaging in moderate-intensity physical activity were manipulated by providing false feedback after a submaximal exercise test. The participants' self-efficacy was measured and compared before and after the exercise test and the participants' enjoyment of physical activity was assessed after the exercise test. It was found that exercise self-efficacy was successfully manipulated in the expected direction in both conditions, which significantly influenced the participants' enjoyment of physical activity. After the exercise test, the participants in the low-efficacy condition reported lower enjoyment scores relative to the high-efficacy participants. These results suggest that self-efficacy may have an important influence on the enjoyment of physical activity among Chinese adolescents. We recommend that physical activity promotion programs should be tailored to enhance adolescents' self-efficacy beliefs and enjoyment of the experience of physical activity.

    Guided by the self-determination theory, the purpose of this study was to examine the predictive strength of self-determined motivation toward motivational outcomes (perceived enjoyment, perceived effort, physical activity behaviors) for 286 middle school students in physical education. Analyses indicated that intrinsic motivation, identified regulation, and introjected regulation were positively related to students' enjoyment, perceived effort, and physical activity, whereas amotivation was negatively associated with students' enjoyment and perceived effort. The findings highlighted the importance of higher self-determined motivation (intrinsic motivation and identified regulation) in students' perceived enjoyment, effort, and physical activity behaviors. This study supports the use of self-determination theory to investigate students' motivational outcomes in school physical education.

    The study aims to explore the effects of receiving active videogame (AVG) feedback and playing experience on individuals' moderate-to-vigorous physical activity (MVPA) and perceived enjoyment. This was a within-subject design study. The participants included 36 (n = 15 and 21 for boys and girls, respectively) fourth graders enrolled in a rural elementary school in southern Georgia area. The experiment lasted for 6 weeks with each week including three sessions. The participants were assigned in either front row (sensor feedback) or back row (no sensor feedback) during practice, which was alternated in different sessions. Two different dance games were played during the study with each game implemented for 3 weeks. The MVPA was measured with GT3X+ accelerometers. Physical activity (PA) enjoyment was assessed after the completion of the first two and last two sessions of each game. A repeated one-way ANOVA (analysis of variance) was used to examine the effects of AVG feedback and game on MVPA. A repeated one-way MANOVA (multivariate analysis of variance) was conducted for each game to examine the effects of experience and AVG feedback on enjoyment and MVPA. No effects of AVG feedback were found for MVPA or enjoyment (P > 0.05). The effects of experience on MVPA were found for Just Dance Kids 2014 with experience decreased MVPA (P < 0.05). Students who practiced dance AVG without receiving feedback still demonstrated positive affection and accumulated similar MVPA than when practicing while receiving feedback. Experience for certain dance games tends to decrease PA intensity.

    Motor, cognitive, social and behavioral problems have been found to persist in adolescents born extremely preterm. Leisure participation has been associated with health benefits; however, few studies have explored leisure participation in this population. The aim of this study was to describe leisure participation in adolescents born at ≤29week gestation. Secondary aims were to identify potential differences in participation related to sex, age, motor competence, and cognitive ability, and between adolescents born preterm and their siblings born at term. This cross-sectional study included 128 adolescents (mean age: 16.0years; 67 females) with a mean gestational age of 26.5weeks. All participants, as well as 22 siblings born at term, completed the Children's Assessment of Participation and Enjoyment. Participation levels were highest in social and recreational activities, and lowest in active-physical and skill-based activities. Boys participated in more active-physical activities (p=0.01) and more often (pleisure activities needs to be promoted in boys, and especially in girls with a history of prematurity. Activities should be adapted to sex and individual skill level in order to promote participation. Copyright © 2014 Elsevier Ltd. All rights reserved.

    This study investigated the predictive strength of perceived competence and enjoyment on students' physical activity and cardiorespiratory fitness in physical education classes. Participants (N = 307; 101 in Grade 6, 96 in Grade 7, 110 in Grade 8; 149 boys, 158 girls) responded to questionnaires assessing perceived competence and enjoyment of physical education, then their cardiorespiratory fitness was assessed on the Progressive Aerobic Cardiovascular Endurance Run (PACER) test. Physical activity in one class was estimated via pedometers. Regression analyses showed enjoyment (R2 = 16.5) and perceived competence (R2 = 4.2) accounted for significant variance of only 20.7% of physical activity and, perceived competence was the only significant contributor to cardiorespiratory fitness performance (R2 = 19.3%). Only a small amount of variance here leaves 80% unaccounted for. Some educational implications and areas for research are mentioned.

    Youths with intellectual disabilities (ID) exhibit low levels of physical activity, but the underlying contributors to behavior are unclear. We compared physical activity enjoyment, perceived barriers, beliefs, and self-efficacy among adolescents with ID and typically developing (TD) adolescents. A questionnaire was administered to 38 adolescents with ID (mean age, 16.8 years) and 60 TD adolescents (mean age, 15.3 years). Of the original 33 questionnaire items, 23 met the test-retest reliability criteria and were included in the group comparisons. Fewer adolescents with ID reported that they have someone with whom to do physical activity (64% vs 93%: P physical activities were too hard to learn (41% vs 0%; P physical activity would be good for their health (92% vs 100%; P = .05). More adolescents with ID reported a dislike of individual physical activities (P = .02). A large percentage of adolescents with ID (84%) responded that they were good at doing physical activities, but the difference between groups was only of borderline significance (95% of TD adolescents, P = .06). Adolescents shared many of the same perceptions about physical activity, but some important differences between groups were identified.

    The present study aimed to contrast the mediating magnitude of self-efficacy and enjoyment connecting peer support and adolescents' physical activity (PA). Participants were 9th-12th grade students ( N  = 409; 56.5% boys) who were randomly chosen from six public schools located in Fuzhou city in southeast China. The bootstrapping method in structural equation modeling was conducted to examine the direct and indirect effects of peer support on adolescents' PA. Peer support did not directly impact PA. Rather, peer support indirectly influenced PA through either self-efficacy or enjoyment, with self-efficacy demonstrating a stronger mediating effect. Additionally, we found a significant serial mediating effect with enjoyment, and self-efficacy sequentially mediated the relationship between peer support and PA. The findings highlight the role of self-efficacy and enjoyment as mediators connecting peer support and PA. Self-efficacy seems to be more important, as it demonstrated a significantly greater mediating effect. © The Author 2017.

    The use of material incentives in healthy lifestyle interventions is becoming widespread. However, self-determination theory (SDT) posits that when material incentives are perceived as controlling, they undermine intrinsic motivation. We analyzed data from the Make Better Choices trial-a trial testing strategies for improving four risk behaviors: low fruit-vegetable intake, high saturated fat intake, low physical activity, and high sedentary activity. At baseline, participants reported the degree to which financial incentives were an important motivator (financial motivation); self-reported enjoyment of each behavior was assessed before and after the 3-week incentivization phase. Consistent with SDT, after controlling for general motivation and group assignment, lower financial motivation predicted more adaptive changes in enjoyment. Whereas participants low in financial motivation experienced adaptive changes, adaptive changes were suppressed among those high in financial motivation.

    This study was designed to explore the effects of a health-related physical fitness physical education model on students' physical activity, perceived competence, and enjoyment. 61 students (25 boys, 36 girls; M age = 12.6 yr., SD = 0.6) were assigned to two groups (health-related physical fitness physical education group, and traditional physical education group), and participated in one 50-min. weekly basketball class for 6 wk. Students' in-class physical activity was assessed using NL-1000 pedometers. The physical subscale of the Perceived Competence Scale for Children was employed to assess perceived competence, and children's enjoyment was measured using the Sport Enjoyment Scale. The findings suggest that students in the intervention group increased their perceived competence, enjoyment, and physical activity over a 6-wk. intervention, while the comparison group simply increased physical activity over time. Children in the intervention group had significantly greater enjoyment.

    High-intensity interval training (HIIT) has been shown to improve cardiometabolic health during supervised lab-based studies but adherence, enjoyment, and health benefits of HIIT performed independently are yet to be understood. We compared adherence, enjoyment, and cardiometabolic outcomes after 8 weeks of HIIT or moderate-intensity continuous training (MICT), matched for energy expenditure, in overweight and obese young adults. 17 adults were randomized to HIIT or MICT. After completing 12 sessions of supervised training over 3 weeks, participants were asked to independently perform HIIT or MICT for 30 min, 4 times/week for 5 weeks. Cardiometabolic outcomes included cardiorespiratory fitness (VO 2 peak), lipids, and inflammatory markers. Exercise enjoyment was measured by the validated Physical Activity Enjoyment Scale. Exercise adherence (93.4 ± 3.1% vs. 93.1 ± 3.7%, respectively) and mean enjoyment across the intervention (100.1 ± 4.3 vs. 100.3 ± 4.4, respectively) were high, with no differences between HIIT and MICT (p > .05). Similarly, enjoyment levels did not change over time in either group (p > .05). After training, HIIT exhibited a greater decrease in low-density lipoprotein cholesterol than MICT (-0.66 mmol L -1 vs. -0.03 mmol L -1 , respectively) and a greater increase in VO 2 peak than MICT (p HIIT (+0.5 pg mL -1 and + 31.4 nmol L -1 , respectively) and decreased in MICT (-0.6 pg mL -1 and -6.7 nmol L -1 , respectively, p HIIT is enjoyable and has high unsupervised adherence rates in overweight and obese adults. However, HIIT may be associated with an increase in inflammation with short-term exercise in this population.

    Background Some active video games have been found to promote physical activity adherence because of enjoyment. However, many active games are exercise themed, which may interfere with the distracting properties that make game-based exercise more enjoyable than traditional exercise. This study compared exercise-themed and game-themed active games to investigate differences in energy expenditure and enjoyment. Method Young adults (N = 100, 50 female, 55 overweight, aged 18–35 years) played two of four Wii Fit games (one aerobic game and one balance game per person) for 10 min each. Of the two aerobic games, one was exercise themed (jogging) and the other was game themed (hula hooping). Both balance games were game themed. Energy expenditure and enjoyment were measured. Results After adjustment for gender and weight, aerobic games produced 2.70 kcal/kg-1/h-1 (95% confidence interval 2.41, 3.00) greater energy expenditure than balance games (p games were more enjoyable (p games, jogging produced greater energy expenditure than hula hooping in normal-weight and male participants (p .17). Hula hooping was enjoyed more than jogging (p = .008). Enjoyment predicted energy expenditure in aerobic games (B = 0.767, p = .010). Conclusions Aerobic games produced greater energy expenditure but lower enjoyment than balance games, and a game-themed aerobic game was found more enjoyable than an exercise-themed aerobic game. Integrating more strenuous activity into entertaining games instead of games that simply simulate exercise may be a fruitful avenue for active game development. PMID:22920810

    Positive social interactions contribute to the sense that one's life has meaning. Enjoyment of feelings associated through social interaction motivates humans to build social connections according to their personal preferences. Therefore, we hypothesized that social interaction itself activates the reward system in a manner that depends upon individual interaction preferences. To test this hypothesis, we conducted a functional magnetic resonance imaging (fMRI) study in which 38 participants played a virtual ball-toss game in which the number of ball tosses to the participant was either similar to (normal-frequency condition) or higher than (high-frequency condition) the number of tosses to the other players. Participants reported greater-than-anticipated enjoyment during the high-frequency condition, suggesting that receiving a social reward led to unexpected positive feelings. Consistent with this, the high-frequency condition produced stronger activation in the ventral striatum, which is part of the reward system, and the precuneus, representing positive self-image, which might be translated to social reward. Furthermore, ventral striatal activation covaried with individual participants' preference for interactions with others. These findings suggest that an elevated frequency of social interaction is represented as a social reward, which might motivate individuals to promote social interaction in a manner that is modulated by personal preference.

    New active videogames (AVGs) may provide youth an alternative to traditional play. The purpose of this study was to compare the physical activity energy expenditure (PAEE), intensity, and enjoyment of AVGs with those of seated videogames (SVGs). Youth (8-17 years old) volunteered to play a random selection of six (two SVGs, four AVGs) videogames for 6-10 minutes each. Prior to participation, height, weight, and resting metabolic rate (RMR) were measured. A portable metabolic analyzer was worn during the games to measure total energy expenditure, and PAEE was calculated as (total energy expenditure - measured RMR). An accelerometer was worn on the right hip to measure intensity in counts/minute and steps/minute. Youth were classified as child (8-12 years old) versus teen (13-17 years old), healthy weight (body mass index [BMI] <85th percentile) versus overweight (BMI ≥85th percentile), and male versus female. A three-way mixed-model analysis of variance was used to compare differences in PAEE (metabolic equivalents [METs] and kcal/minute) with sex, weight status, and age group as main effects, including Bonferroni's adjustment. Most AVGs were moderate to vigorous intensity (4.6±0.1 METs; range, 2.8-6.6 METs), where steps/minute (lower-body movement) was positively related to PAEE (R(2)=0.68). All SVGs were classified as light intensity (1.7±0.0 METs). PAEE (kcal/minute) was significantly higher during AVGs and for teens, males, and overweight youth. There was no significant difference in enjoyment between AVGs and SVGs. AVGs elicited sufficient energy cost to be a suitable alternative for traditional play and may contribute to the recommended dose of physical activity, particularly in teens, males, and overweight youth.

    This study investigated the processes leading to enjoyment of casual videogames on both mobile devices and console systems. Building upon a foundation in mental models theory and the psychology of play, the study focuses on how performance and experience-based variables impact enjoyment of casual videogames played on mobile devices and console devices. The grounding assumption of this research is that playing videogames produces enjoyment that contributes to mental health in the form of a brief distraction from the stress of daily life, social connections with family and friends through casual gameplay, and, in some cases, a compelling reason to engage in physical activity. A student sample of players (n=363) played a variety of casual games on mobile (iPad(®) or iPod(®) Touch(®) [Apple, Cupertino, CA]) or console (Wii™ [Nintendo, Japan], Xbox(®) 360 Kinect(®) [Microsoft, Redmond, WA], or PS3™ Move [Sony, Tokyo, Japan]) platforms. They then answered a questionnaire assessing their evaluations of the game's interactivity level, their sense of spatial presence in the game, their perception of the game's realism, and, most importantly, their enjoyment. Path analysis demonstrated the interrelationships among these variables. The results show that spatial presence is a powerful predictor of videogame enjoyment for both console- and mobile-based casual games. Patterns of prediction for games on each platform, as demonstrated using path analysis, were similar and aligned with predictions based on mental models and the psychology of play. The psychological theory of play and the mental models perspective offer firm theoretical grounds for understanding how enjoyment is wrought in the process of playing casual games. The relationships among interactivity, spatial presence, perceived reality, and enjoyment hold for games played on handheld or console devices. Furthermore, this study is one of the first to demonstrate these relationships and test them simultaneously

    Physical activity (PA) is enjoyable, but there are barriers to participation. TV viewing is highly enjoyable with limited barriers. Exercising while viewing TV may impact enjoyment, exercise self-efficacy, and barriers to PA, compared with exercising without TV. 58 sedentary, overweight adults were randomized to 1 of 2 PA prescriptions: one that increased PA during TV viewing (TV Commercial Stepping), and another that focused solely on PA (Walking). Random effects models tested changes in enjoyment of TV and PA, exercise self-efficacy, and barriers to PA across time (baseline, 3, and 6 months) and PA prescription during a 6-month PA intervention. At baseline, TV was more enjoyable than PA. Over the 6-month intervention, enjoyment of TV viewing did not change, but enjoyment of PA and exercise self-efficacy significantly increased, while barriers to PA significantly decreased for both groups compared with baseline (P exercise increased, and barriers to being active were reduced for previously sedentary adults participating in a behavioral PA intervention. These findings highlight the importance of encouraging inactive adults to engage in some form of PA, whether it occurs with or without TV viewing.

    Evidence suggests the role of physical activity (PA) in management of clinical symptoms of fibromyalgia. However, very little is known regarding the psychological correlates of PA in patients with fibromyalgia. Therefore, this study examined the association between exercise enjoyment (EE) and PA in women with fibromyalgia. 19 women with fibromyalgia completed a laboratory session, where EE was assessed using a self-report questionnaire immediately after 20 min of light-intensity biking. Muscle pain ratings (MPR) in the legs were assessed during exercise, and changes in clinical pain intensity after exercise were computed. PA was assessed subjectively using a self-report questionnaire and objectively using an accelerometer for one week. Results from correlation analyses indicated that EE was associated with the self-reported amount of PA (rs=0.61, R(2)=0.37, pfibromyalgia. Future research is needed to develop interventions to maximize EE to promote PA in this clinical population. © Georg Thieme Verlag KG Stuttgart · New York.

    The purpose of the study was to compare the effects of a Kinect active videogame (AVG) and the Sports, Play, and Active Recreation for Kids (SPARK) intervention in improving children's health-related fitness and physical activity (PA) enjoyment. A total of 65 students from both third and fourth grade in a rural elementary school participated in the study. The third graders (N = 29, mean age = 9.1 years, 10 boys, mean body mass index [BMI] = 20.1) were assigned to a SPARK physical education group, while the fourth graders (N = 36, mean age = 10.2 years, 15 boys, mean BMI = 20.3) were enrolled in the Kinect AVG group. The intervention lasted for 6 weeks, with each week including three practice sessions (∼40 minutes per session). All participants were measured on their health-related fitness by testing their performance in the 15-m Progressive Aerobic Cardiovascular Endurance Run (PACER), curl-ups, and push-ups both before and after the interventions. Participants' PA enjoyment was measured immediately after the first and last session's practice. Various ANCOVA tests were conducted to analyze the intervention effects on the changes of health-related fitness performances and enjoyment while controlling for baseline values, gender, and BMI. Various MANOVA tests were used to examine the intervention effects on PA levels during three practice sessions. Participants in AVG group had greater improvement in 15-m PACER test (P < 0.001), as well as PA enjoyment (P < 0.05), than those in SPARK group. The AVG group generated higher light PA and lower sedentary time for three (P < 0.05 to P < 0.001) and two sessions (P < 0.05 and P < 0.001), respectively. In addition, the AVG group accumulated higher moderate-to-vigorous physical activity (MVPA) for the first session (P < 0.01), while the SPARK group generated higher MVPA for the third session (P < 0.001). No MVPA difference was found between groups for another session. A

    Active-input videogames could provide a useful conduit for increasing physical activity by improving a child's self-confidence, physical activity enjoyment, and reducing anxiety. Therefore this study evaluated the impact of (a) the removal of home access to traditional electronic games or (b) their replacement with active-input videogames, on child self-perception, enjoyment of physical activity, and electronic game use anxiety. This was a crossover, randomized controlled trial, conducted over a 6-month period in participants' family homes in metropolitan Perth, Australia, from 2007 to 2010. Children 10-12 years old were recruited through school and community media. Of 210 children who were eligible, 74 met inclusion criteria, and 8 withdrew, leaving 66 children (33 girls) for analysis. A counterbalanced randomized order of three conditions sustained for 8 weeks each: No home access to electronic games, home access to traditional electronic games, and home access to active-input electronic games. Perception of self-esteem (Harter's Self Perception Profile for Children), enjoyment of physical activity (Physical Activity Enjoyment Scale questionnaire), and anxiety toward electronic game use (modified Loyd and Gressard Computer Anxiety Subscale) were assessed. Compared with home access to traditional electronic games, neither removal of all electronic games nor replacement with active-input games resulted in any significant change to child self-esteem, enjoyment of physical activity, or anxiety related to electronic games. Although active-input videogames have been shown to be enjoyable in the short term, their ability to impact on psychological outcomes is yet to be established.

    2017-09-01

    Full Text Available The present paper examined the full sequence of the Hierarchical Model of Motivation in physical education (PE including motivational climate, basic psychological needs, intrinsic motivation, and related links to contextual enjoyment, knowledge, performance, and total moderate to vigorous physical activity (MVPA. Gender differences and correlations with body mass index (BMI were also analyzed. Cross-sectional data was represented by self-reports and objective assessments of 770 middle school students (52% of girls in North-East Finland. The results showed that task-involving climate in girls’ PE classes was related to enjoyment and knowledge through physical competence and intrinsic motivation, whereas task-involving climate was associated with enjoyment and knowledge via competence and autonomy, and total MVPA via autonomy, intrinsic motivation, and knowledge within boys. This may indicate that girls and boys perceive PE classes in a different way. Graded PE assessments appeared to be essential in motivating both girls and boys to participate in greater total MVPA, whereas BMI was negatively linked with competence and social relatedness only among girls. Although, the current and previous empirical findings supported task-involving teaching methods in PE, in some cases, ego-involving climate should be considered. Therefore, both task- and ego-involving teaching practices can be useful ways of developing preferred behaviors in PE classes.

    The aim of the study was to investigate if adolescents' perceived physical competence towards physical activity (PA), and autonomous motivation and enjoyment in physical education (PE) during early adolescence can predict amount and intensity of self-reported physical activity six years later. This study utilized a 6-year longitudinal data set collected within Finnish school settings. Students responded to questionnaires measuring their perceived physical competence towards physical activity, and autonomous motivation and enjoyment in PE during their first year at middle school (Grade 7), and their PA engagement during their last year in high school (Grade 12). A sample of 333 students (200 girls, 133 boys; M age=12.41, years, SD=.27) participated in the study. Perceived physical competence in physical activity was assessed by the sport competence dimension of the Physical Self-Perception Profile, autonomous motivation in PE was assessed by the Sport Motivation Scale and enjoyment in PE by the Sport Enjoyment Scale. Students' self-reported metabolic equivalent (MET) and PA intensity (light [LPA], moderate [MPA], vigorous [VPA]) was calculated from the short form of International Physical Activity Questionnaire. Perceived physical competence towards physical activity significantly predicted total METs (β=.28), MPA (β=.18) and VPA (β=.29) six years later. Autonomous motivation and enjoyment in PE at Grade 7, however, were not significant predictors of later PA. The results of this study support the proposition that self-perception of an individual's abilities arising from interactions with the environment related to PA during early puberty has an influential effect on later PA behaviour.

    The purpose of this study was to investigate the importance of enjoyment of exercise in a health care-based intervention aimed at promoting physical exercise in primary health care patients. In a controlled study design, the intervention group was offered a wide range of group exercises over 3 months, followed by support in designing their own exercise program. The control group received usual care. Enjoyment of exercise and exercise level were measured. Associations between enjoyment and exercise level were analyzed using Spearman's rank correlation coefficients. Changes in enjoyment between and within study groups were analyzed by the independent and paired t-test. Associations were found between enjoyment and exercise level (r=0.36, Pexercise level (r=0.34, Pexercise was 25% higher in the intervention group than in the control group (Phealth care patients, enjoyment of exercise was associated with exercise level. Enjoyment of exercise seems to be a mediator of exercise level. Furthermore, health care-based interventions seem to be able to affect enjoyment of exercise. Enjoyment of exercise may be important for the long-term effectiveness, of health care-based interventions.

    This study investigates the enjoyment and cohesion of school children participating in a school-based high-intensity physical activity (PA) intervention. Both enjoyment and cohesion have been found to be important factors for adherence to regular physical and sport activity, an important outcome of PA interventions. The sample consisted of 300 pupils (mean age: 9.3 years; 52.7% female) assigned to a team sport intervention, an individual sport intervention, or a control group for 10 months. The Physical Activity Enjoyment Scale and Youth Sport Environment Questionnaire were used to measure enjoyment and cohesion. The Yo-Yo IR1C test determined fitness improvements. Results showed that enjoyment and cohesion (social) measured at the beginning of the intervention significantly predict fitness improvements achieved after 10 months. No differing developmental effects over time could be found in the intervention groups with regard to cohesion and enjoyment when comparing them to the control group. However, enjoyment and cohesion (social) significantly decreased in the groups that performed individual sports. Team sports seem to be more advantageous for the development of enjoyment and cohesion, which are both factors that positively impact the health outcomes of the intervention.

    The current study examined associations between physical education (PE) class enjoyment and sociodemographic, personal, and perceived school environment factors among early adolescent girls. Participants included 1,511 sixth-grade girls who completed baseline assessments for the Trial of Activity in Adolescent Girls, with 50% indicating they enjoyed PE class a lot. Variables positively associated with PE class enjoyment included physical activity level, perceived benefits of physical activity, self-efficacy for leisure time physical activity, and perceived school climate for girls' physical activity as influenced by teachers, while body mass index was inversely associated with PE class enjoyment. After adjusting for all variables in the model, PE class enjoyment was significantly greater in Blacks than in Whites. In model testing, with mutual adjustment for all variables, self-efficacy was the strongest correlate of PE class enjoyment, followed by perceived benefits, race/ethnicity, and teachers' support for girls' physical activity, as compared to boys, at school. The overall model explained 11% of the variance in PE class enjoyment. Findings suggest that efforts to enhance girls' self-efficacy and perceived benefits and to provide a supportive PE class environment that promotes gender equality can potentially increase PE class enjoyment among young girls.

    With exergames (as with physical activity in general), more intense and longer-duration game play should accrue more health benefits. Exergames, however, appear to be played for relatively short durations, often at medium or lower intensities. Ostensibly games are played for fun or enjoyment. Enhancing the fun or enjoyment experienced during exergame play should enhance the intensity and duration of physical activity, and thereby the health benefits. Research, reviewed herein, indicates fun and/or enjoyment in games are inherently laden with psychosocial, physiological, and embodiment substrates. Physical activity may also have separate or closely related psychosocial, physiological, and embodiment enjoyment substrates. Research is needed to integrate these levels of experience and to identify the game mechanics that enhance, and even maximize, the fun or enjoyment experienced in exergames, to thereby increase the health benefit.

    Full Text Available The aim of this study was to translate and validate of the Physical Activity Enjoyment Scale (PACES, from Mullen et al. version in Portuguese athletes, invariance across genders and nature sports and swimming, as well as, external validity, through the Portuguese version of BRSQ. Athletes (n=1032; 273 nature sports, 759 swimming with an average age of 18,95 ± 6,59 years participated in this study. Confirmatory factor analysis (maximum likelihood, multigroup analysis (measurement invariance and correlation analysis were used for data analyzed.

Enjoyment was, on the one hand, found to be positively and significantly correlated with identified regulation (r=0,82, integrated regulation (r=0,62 and intrinsic motivation (r=0,90. On the other, it was negatively and significantly correlated with amotivation (r=-0,25 and external and introjected regulation (r=-0,42; -0,38, respectively. Those findings allow concluding that PACES can be used to measure enjoyment in the future studies, thus filling an existing gap to date.

    2015-08-01

    Nintendo(®) (Kyoto, Japan) "Wii™ Sports Boxing" ("Wii Boxing") and Xbox(®) (Microsoft, Redmond, WA) "Kinect(®) Sports Boxing" ("Kinect Boxing") are both boxing simulation videogames that are available for two different active videogame (AVG) systems. Although these AVGs are similar, the style of gameplay required is different (i.e., upper body only versus total body movements) and may alter physical activity intensity and one's preference for playing one game over the other. AVGs that elicit the greatest physiologic challenge and are preferred by users should be identified in an effort to enhance the efficacy of physical activity interventions and programs that include AVGs. The mean heart rate (HRmean) and peak heart rate (HRpeak) for 27 adults (22.7±4.2 years old) were recorded during four 10-minute conditions: seated rest, treadmill walking at 3 miles/hour, "Wii Boxing," and "Kinect Boxing." Upon completion of all four conditions, participants indicated which condition they preferred, and HRmean and HRpeak were calculated as a percentage of age-predicted maximum heart rate to classify physical activity intensity for the three activity conditions (treadmill, "Wii Boxing," and "Kinect Boxing"). "Kinect Boxing" significantly (P<0.001) increased percentage HRmean (64.1±1.6 percent of age-predicted maximum) and percentage HRpeak (76.5±1.9 percent) above all other conditions: Wii HRmean, 53.0±1.2 percent; Wii HRpeak, 61.8±1.5 percent; treadmill HRmean, 52.4±1.2 percent; treadmill HRpeak, 55.2±2.2 percent. Percentage HRpeak for "Kinect Boxing" was great enough to be considered a vigorous-intensity physical activity. There was no difference (P=0.55) in percentage HRmean between "Wii Boxing" and treadmill walking. Participants also preferred "Kinect Boxing" (P<0.001; n=26) to all other conditions ("Wii Boxing," n=1; treadmill n=0). "Kinect Boxing" was the most preferred and the only condition that was physiologically challenging enough to be classified as a

  20. Music enjoyment with cochlear implantation.

    2018-10-01

    Since the advent of cochlear implant (CI) surgery in the 1960s, there have been remarkable technological and surgical advances enabling excellent speech perception in quiet with many CI users able to use the telephone. However, many CI users struggle with music perception, particularly with the pitch-based and melodic elements of music. Yet remarkably, despite poor music perception, many CI users enjoy listening to music based on self-report questionnaires, and prospective studies have suggested a disassociation between music perception and enjoyment. Music enjoyment is arguably a more functional measure of one's listening experience, and thus enhancing one's listening experience is a worthy goal. Recent studies have shown that re-engineering music to reduce its complexity may enhance enjoyment in CI users and also delineate differences in musical preferences from normal hearing listeners.

    The Wii Fit series (Nintendo Inc., Japan) provides active video games (AVGs) to help adults to maintain a sufficient level of daily physical activity (PA). The second generation of home AVG consoles is now emerging with new game modalities (including a portable mini screen in the case of the new Wii U). The present study was performed to investigate the intensity and enjoyment of Wii Fit U games among adults. Metabolic equivalent (METs, i.e., intensity) of the Wii Fit U activities were evaluated using metabolic chambers in 16 sedentary adults (8 women and 8 men). A short version of the physical activity enjoyment scale was completed for each activity. Wii Fit U activities were distributed over a range from 2.2  ±  0.4 METs (Hula dance) to 4.7  ±  1.2 (Hip-hop dance). Seven activities were classified as light-intensity PA (game modality does not induce higher METs. Men exercised at higher intensities than women. There was no correlation between enjoyment and MET values in women or men. More and more moderate-intensity activities are available through video gaming, but the average intensity (3.2  ±  0.6) is still low. Users should be aware that AVGs alone cannot fulfill the recommendations for PA, and the video games industry still must innovate further to enhance gaming intensity and make the tool more attractive to health and fitness professionals.

  3. Harmonic Structure Predicts the Enjoyment of Uplifting Trance Music.

    2016-01-01

    An empirical investigation of how local harmonic structures (e.g., chord progressions) contribute to the experience and enjoyment of uplifting trance (UT) music is presented. The connection between rhythmic and percussive elements and resulting trance-like states has been highlighted by musicologists, but no research, to our knowledge, has explored whether repeated harmonic elements influence affective responses in listeners of trance music. Two alternative hypotheses are discussed, the first highlighting the direct relationship between repetition/complexity and enjoyment, and the second based on the theoretical inverted-U relationship described by the Wundt curve. We investigate the connection between harmonic structure and subjective enjoyment through interdisciplinary behavioral and computational methods: First we discuss an experiment in which listeners provided enjoyment ratings for computer-generated UT anthems with varying levels of harmonic repetition and complexity. The anthems were generated using a statistical model trained on a corpus of 100 uplifting trance anthems created for this purpose, and harmonic structure was constrained by imposing particular repetition structures (semiotic patterns defining the order of chords in the sequence) on a professional UT music production template. Second, the relationship between harmonic structure and enjoyment is further explored using two computational approaches, one based on average Information Content, and another that measures average tonal tension between chords. The results of the listening experiment indicate that harmonic repetition does in fact contribute to the enjoyment of uplifting trance music. More compelling evidence was found for the second hypothesis discussed above, however some maximally repetitive structures were also preferred. Both computational models provide evidence for a Wundt-type relationship between complexity and enjoyment. By systematically manipulating the structure of chord

    To identify factors that enhance the enjoyment of music in cochlear implant (CI) recipients. Specifically, we assessed the hypothesis that variations in reverberation time (RT60) may be linked to variations in the level of musical enjoyment in CI users. Prospective analysis of music enjoyment in normal-hearing individuals. Single tertiary academic medical center. Normal-hearing adults (N = 20) were asked to rate a novel 20-second melody on three enjoyment modalities: musicality, pleasantness, and naturalness. Subjective rating of music excerpts. Participants listened to seven different instruments play the melody, each with five levels (0.2, 1.6, 3.0, 5.0, 10.0 s) of RT60, both with and without CI simulation processing. Linear regression analysis with analysis of variance was used to assess the impact of RT60 on music enjoyment. Without CI simulation, music samples with RT60 = 3.0 seconds were ranked most pleasant and most musical, whereas those with RT60 = 1.6 seconds and RT60 = 3.0 seconds were ranked equally most natural (all p < 0.05). With CI simulation, music samples with RT60 = 0.2 seconds were ranked most pleasant, most musical, and most natural (all p < 0.05). Samples without CI simulation show a preference for middle-range RT60, whereas samples with CI simulation show a negative linear relationship between RT60 and musical enjoyment, with preference for minimal reverberation. Minimization of RT60 may be a useful strategy for increasing musical enjoyment under CI conditions, both in altering existing music as well as in composition of new music.

    In the mid-1970s, the Philippine Commission on Population (POPCOM) began to use entertainment programs for reaching people with messages on population and development issues. 2 major motion pictures contained family planning (FP) messages. Radio dramas, print media, and theater also were used to convey FP messages. The early experiments were continued in the late 1980s through the work of the Philippine Center for Population and Development (PCPD). PCPD, with the assistance of the Johns Hopkins University/Population Communication Services (JHU/PCS) project, embarked on a program which used popular music to encourage young people to become sexually responsible adults. In 1990, the Philippine Non-Governmental Organization Council (PNGOC), the Department of Health (DOH) and JHU/PCS began an effort funded by USAID to form a coalition with the entertainment community for social development causes. DOH, JHU/PCS, and USAID wanted to promote FP and health through the Enter-Educate concept. PNGOC and JHU/PCS contacted over 20 entertainment organizations and held more than 75 conferences, work shops, and meetings which attended by more than 300 people. The movement of Entertainment for Social Change was launched in October 1991 with the creation of the Enter-Educate Foundation, Inc. (EEF). The aims of EEF include rewards, professional approach, and establishment of a network of dedicated entertainment and social development professionals. In 1993, a television comedy series will focus on FP as well as on maternal and child health. Further plans at the local level include: tree planting; discussions on migration; talks about FP; meetings on community population and environment activities; and networking of organizations involved with youth, the environment, and population. JHU/PCS provides technical assistance for the production, monitoring, and evaluation of the project. With these efforts, the EEF is attempting to focus on the country's biggest problems: population and the

    2012-06-01

    Full Text Available The specific aim of this study was to examine whether motivational climate, perceived physical competence, and exercise motivation predict enjoyment in school physical education within the same sample of adolescents across three years of secondary school. A sample of 639 students (girls = 296, boys = 343 aged between 13- to 15-years at the commencement of the study completed the Intrinsic Motivation Climate in Physical Education Questionnaire, Physical Self-Perception Profile, Physical Education Motivation Scale, and Physical Education Enjoyment Scale. Results derived from path analyses indicated that task-involving motivational climate predicted enjoyment in physical education via perceived physical competence and intrinsic motivation in both girls and boys. In particular, these results supported previous findings of Vallerand et. al (1997 with the self-determination theory and the achievement goal theory. Ego-involving climate was not a significant predictor either in girls or boys. The current results provide continuing support for the investigation of Vallerand's model in the physical education setting, and highlight that motivational climate is an area that requires further evaluation as a contributing factor in the improvement of physical education teaching. A better understanding of the role of motivational climate may assist efforts to promote children's and adolescents' perceived physical competence, intrinsic motivation, and enjoyment in the school physical education setting

    2015-12-01

    Full Text Available Agglomeration economies is a potent tool in socio-economic revamping, rejuvenation and sustenance of regions, this is as a result of the impulse it transmitted through the multiplier effect it is capable of generated. Therefore, this paper underscores the influence of firms structural characteristics on the degree of agglomeration economies enjoyed amongst firms, using the Lagos region as a case study. The first stage in the collection of primary data involves the reconnaissance survey, thereafter one hundred and three questionnaire were administered in twelve industrial estates; one questionnaire in each of the firm. The paper reveals the following structural characteristics as germane to industrial enterprise; age of firms, areal plant size (m², capacity utilization (in percentage, and Labour size and firms investment. The paper has also found out those agglomeration economies enjoyed ranges from transportation, labour, power supply, to joint water supply. The Roy’s Largest Root test employed to test for the significance of the canonical correlations at 0.05 significant levels shows the calculated F-value 3.5247 and the tabulated F-value 2.90. This suggests that the degree of agglomeration economies enjoyed by firms is significantly explained by the size and structural characteristics of the firms. The paper therefore recommends more and active government participation in the industrial scene, given the necessary support for the expansion of firm’s structural characteristics which will lead to increase agglomeration economies enjoyed by these firms.

    2009-04-01

    Browser games--mostly persistent game worlds that can be used without client software and monetary cost with a Web browser--belong to the understudied digital game types, although they attract large player communities and motivate sustained play. The present work reports findings from an online survey of 8,203 players of a German strategy browser game ("Travian"). Results suggest that multiplayer browser games are enjoyed primarily because of the social relationships involved in game play and the specific time and flexibility characteristics ("easy-in, easy-out"). Competition, in contrast, seems to be less important for browser gamers than for users of other game types. Findings are discussed in terms of video game enjoyment and game addiction.

    The purpose of this study was to identify student clusters with homogenous profiles in perceptions of task- and ego-involving, autonomy, and social relatedness supporting motivational climate in school physical education. Additionally, we investigated whether different motivational climate groups differed in their enjoyment in PE. Participants of the study were 2 594 girls and 1 803 boys, aged 14-15 years. Students responded to questionnaires assessing their perception of motivational climate and enjoyment in physical education. Latent profile analyses produced a five-cluster solution labeled 1) 'low autonomy, relatedness, task, and moderate ego climate' group', 2) 'low autonomy, relatedness, and high task and ego climate, 3) 'moderate autonomy, relatedness, task and ego climate' group 4) 'high autonomy, relatedness, task, and moderate ego climate' group, and 5) 'high relatedness and task but moderate autonomy and ego climate' group. Analyses of variance showed that students in clusters 4 and 5 perceived the highest level of enjoyment whereas students in cluster 1 experienced the lowest level of enjoyment. The results showed that the students' perceptions of various motivational climates created differential levels of enjoyment in PE classes.

    Play of physically active video games may be a way to increase physical activity and/or decrease sedentary behavior, but games are not universally active or enjoyable. Active games may differ from traditional games on important attributes, which may affect frequency and intensity of play. The purpose of this study was to investigate differences in energy expenditure and enjoyment across four game types: shooter (played with traditional controllers), band simulation (guitar or drum controller), dance simulation (dance mat controller), and fitness (balance board controller). Energy expenditure (METs) and enjoyment were measured across 10 games in 100 young adults age 18-35 yr (50 women). All games except shooter games significantly increased energy expenditure over rest (P games increased energy expenditure by 322% (mean ± SD = 3.10 ± 0.89 METs) and 298% (2.91 ± 0.87 METs), which was greater than that produced by band simulation (73%, 1.28 ± 0.28 METs) and shooter games (23%, 0.91 ± 0.16 METs). However, enjoyment was higher in band simulation games than in other types (P game types (P games can significantly increase energy expended during screen time, but these games are less enjoyable than other more sedentary games, suggesting that they may be less likely to be played over time. Less active but more enjoyable video games may be a promising method for decreasing sedentary behavior.

Results All games except shooter games significantly increased energy expenditure over rest (P games increased energy expenditure by 322 (mean [SD] 3.10 [0.89] METs) and 298 (2.91 [0.87] METs) percent, which was greater than that produced by band simulation (73%, 1.28 [0.28] METs) and shooter games (23%, 0.91 [0.16] METs). However, enjoyment was higher in band simulation games than in other types (P game types (P games can significantly increase energy expended during screen time, but these games are less enjoyable than other more sedentary games, suggesting that they may be less likely to be played over time. Less active but more enjoyable video games may be a promising method for decreasing sedentary behavior. PMID:21364477

    This article explores video game enjoyment originated by games' key characteristic, interactivity. An online experiment (N=500) tested experiences of effectance (perceived influence on the game world) and of being in control as mechanisms that link interactivity to enjoyment. A video game was manipulated to either allow normal play, reduce perceived effectance, or reduce perceived control. Enjoyment ratings suggest that effectance is an important factor in video game enjoyment but that the relationship between control of the game situation and enjoyment is more complex.

    Self-efficacy and enjoyment were examined among 34 middle school children (M age = 12.5 yr.) performing the Progressive Aerobic Cardiovascular Endurance Run (PACER). Exercise self-efficacy (running) and physical activity enjoyment were measured after viewing a video illustrating the PACER, and subsequently following a PACER test. Significantly greater pre- than post-exercise self-efficacy was reported; enjoyment scores did not differ. Ratings of self-efficacy were higher before exercise than after, but enjoyment scores were not significantly different. A significant correlation was found between post-exercise self-efficacy and enjoyment, but not between pre-exercise self-efficacy and enjoyment. Although positive correlations were found between PACER laps and pre-/post-exercise self-efficacy, correlations with ratings of enjoyment were not significant. Exercise self-efficacy was associated with children's beliefs about the task-specific PACER aerobic exercise; however, exercise enjoyment was stable. Children's self-efficacy and enjoyment beliefs should be considered when developing interventional strategies to promote aerobic exercise participation.

    Background High-intensity interval training (HIIT) has been proposed as a time-efficient exercise format to improve exercise adherence, thereby targeting the chronic disease burden associated with sedentary behaviour. Exercise mode (cycling, running), if self-selected, will likely affect the physiological and enjoyment responses to HIIT in sedentary individuals. Differences in physiological and enjoyment responses, associated with the mode of exercise, could potentially influence the uptake and continued adherence to HIIT. It was hypothesised that in young sedentary men, local and systemic oxygen utilisation and enjoyment would be higher during a session of running HIIT, compared to a session of cycling HIIT. Methods A total of 12 sedentary men (mean ± SD; age 24 ± 3 years) completed three exercise sessions: a maximal incremental exercise test on a treadmill (MAX) followed by two experiment conditions, (1) free-paced cycling HIIT on a bicycle ergometer (HIITCYC) and (2) constant-paced running HIIT on a treadmill ergometer (HIITRUN). Deoxygenated haemoglobin (HHb) in the gastrocnemius (GN), the left vastus lateralis (LVL) and the right vastus lateralis (RVL) muscles, oxygen consumption (VO2), heart rate (HR), ratings of perceived exertion (RPE) and physical activity enjoyment (PACES) were measured during HIITCYC and HIITRUN. Results There was a higher HHb in the LVL (p = 0.001) and RVL (p = 0.002) sites and a higher VO2 (p = 0.017) and HR (p HIIT produces higher levels of physiological stress when compared to constant-paced running HIIT. Participants perceived running HIIT to be more enjoyable than cycling HIIT. These findings have implications for selection of mode of HIIT for physical stress, exercise enjoyment and compliance.

    To investigate enjoyment and specific benefits of a swimming intervention for youth with cerebral palsy (CP). Fourteen youth with CP (aged 7 to 17 years, Gross Motor Function Classification System levels I to III) were randomly assigned to control and swimming groups. Walking ability, swimming skills, fatigue, and pain were assessed at baseline, after a 10-week swimming intervention (2/week, 40-50 minutes) or control period, after a 5-week follow-up and, for the intervention group, after a 20-week follow-up period. The level of enjoyment of each swim-session was assessed. Levels of enjoyment were high. Walking and swimming skills improved significantly more in the swimming than in the control group (P = .043; P = .002, respectively), whereas fatigue and pain did not increase. After 20 weeks, gains in walking and swimming skills were retained (P = .017; P = .016, respectively). We recommend a swimming program for youth with CP to complement a physical therapy program.

    Little is known of the early changes in physical activity after lung transplantation. The purposes of this study were: (1) to describe physical activity levels in patients up to 6 months following lung transplantation and (2) to explore predictors of the change in physical activity in that population. This was a prospective cohort study. Physical activity (daily steps and time spent in moderate-intensity activity) was measured using an accelerometer before and after transplantation (at hospital discharge, 3 months, and 6 months). Additional functional measurements included submaximal exercise capacity (measured with the 6-Minute Walk Test), quadriceps muscle torque, and health-related quality of life (measured with the Medical Outcomes Study 36-Item Short-Form Health Survey 36 [SF-36] and the St George's Respiratory Questionnaire). Thirty-six lung transplant recipients (18 men, 18 women; mean age=49 years, SD=14) completed posttransplant measurements. Before transplant, daily steps were less than a third of the general population. By 3 months posttransplant, the largest improvement in physical activity had occurred, and level of daily steps reached 55% of the general population. The change in daily steps (pretransplant to 3 months posttransplant) was inversely correlated with pretransplant 6-minute walk distance (r=-.48, P=.007), daily steps (r=-.36, P=.05), and SF-36 physical functioning (SF-36 PF) score (r=-.59, P=.0005). The SF-36 PF was a significant predictor of the change in physical activity, accounting for 35% of the variation in change in daily steps. Only individuals who were ambulatory prior to transplant and discharged from the hospital in less than 3 months were included in the study. Physical activity levels improve following lung transplantation, particularly in individuals with low self-reported physical functioning. However, the majority of lung transplant recipients remain sedentary between 3 to 6 months following transplant. The role of exercise

    Dropout from organized youth sport has significant adverse health implications. Enjoyment and behavioral intentions have consistently been linked with participation and dropout; however, few studies have investigated these links using a prospective design. This study explored whether enjoyment and intentions to continue predicted dropout behavior at 1-year follow-up. Questionnaires were completed by 327 regular sport participants (mean age = 13.01 y at baseline). After 1 year, 247 individuals (75.5%) continued participating in their main sport and 26 individuals (8%) dropped out. A hierarchical logistic regression model estimated the probability of dropout. In step 1, the following covariates were included: age, sex, competition level, perceived competence, parental support, coach-athlete relationship, friendship quality, and peer acceptance. In step 2, enjoyment and intentions to continue were included. Step 1 indicated that age, parental support, coach-athlete relationship quality, and peer acceptance were significantly associated with dropout. Step 2 explained further variance in dropout, with both enjoyment and intentions inversely associated with dropout. Peer acceptance was the only covariate to remain significantly associated with dropout in step 2. Findings support the use of enjoyment and behavioral intentions as indicators of sport participation/dropout behavior and may aid the development of interventions aimed at preventing future dropout.

    The aim of this study was to investigate the relations among situational motivational climate, dispositional approach and avoidance achievement goals, perceived sport ability, and enjoyment in Finnish male junior ice hockey players. The sample comprised 265 junior B-level male players with a mean age of 17.03 years (SD = 0.63). Players filled questionnaires tapping their perceptions of coach motivational climate, achievement goals, perceived sport ability, and enjoyment. For the statistical analysis, players were divided into high and low perceived sport ability groups. Multigroup structural equation modeling (SEM) revealed an indirect path from task-involving motivational climate via task-approach goal to enjoyment. Additionally, SEM demonstrated four other direct associations, which existed in both perceived ability groups: from ego-involving motivational climate to ego-approach and ego-avoidance goals; from ego-approach goal to ego-avoidance goal; and from task-avoidance goal to ego-avoidance goal. Additionally, in the high perceived sport ability group, there was an association from task-involving motivational climate to enjoyment. The results of this study reveal that motivational climate emphasizing effort, personal development and improvement, and achievement goal mastering tasks are significant elements of enjoyment in junior ice hockey. © 2015 John Wiley & Sons A/S.

  17. Unconventional Consumption Methods and Enjoying Things Consumed: Recapturing the "First-Time" Experience.

    O'Brien, Ed; Smith, Robert W

    2018-06-01

    People commonly lament the inability to re-experience familiar things as they were first experienced. Four experiments suggest that consuming familiar things in new ways can disrupt adaptation and revitalize enjoyment. Participants better enjoyed the same familiar food (Experiment 1), drink (Experiment 2), and video (Experiments 3a-3b) simply when re-experiencing the entity via unusual means (e.g., eating popcorn using chopsticks vs. hands). This occurs because unconventional methods invite an immersive "first-time" perspective on the consumption object: boosts in enjoyment were mediated by revitalized immersion into the consumption experience and were moderated by time such that they were strongest when using unconventional methods for the first time (Experiments 1-2); likewise, unconventional methods that actively disrupted immersion did not elicit the boost, despite being novel (Experiments 3a-3b). Before abandoning once-enjoyable entities, knowing to consume old things in new ways (vs. attaining new things altogether) might temporarily restore enjoyment and postpone wasteful replacement.

    A mixed-methods design was used to explore the outcomes of a 6-wk, occupational therapist-led Comfortable Cafeteria program designed to build cafeteria supervisors' and students' capacity to create a positive mealtime environment so that all students can successfully participate in and enjoy a healthy meal and socialization with peers. Students whose scores were in the low and mid-range at the outset had statistically significant improvements in pretest-posttest visual analog scale ratings of participation and enjoyment. Cafeteria supervisors demonstrated statistically significant improvements in their perceptions of knowledge and skills to supervise and to encourage healthy eating. Qualitative findings add further insight into the program, suggesting that students learned prosocial values (e.g., being kind, helping others), supervisors actively encouraged positive social interaction, and occupational therapists enjoyed implementing the program and recognized positive supervisor and student changes as a result of integrating services in the cafeteria.

    Constructivist learning allows students to be actively involved in the learning process and thus the learning to be permanent. It makes the lesson more interesting and enjoyable compared to classical learning where students are passive and get bored quickly. When students engage in activities during the learning process, they enjoy it more. And there is no doubt that games help this a lot. In this project, a game has been designed to make it more entertaining to learn the periodical table for the students. In this game, a huge periodical table (with empty columns) is drawn with acrylic paint in the school yard. Acrylic paint is preferred because it is resilient to outdoor conditions, quick drying and relatively durable. Besides its functionality in the game, the presence of the huge periodical table in the yard boosts students' motivation for scientific activities. Students are taught about the periodical table in their Chemistry lesson a week before the game is to be played. They are informed about the game and asked to bring some sportswear to wear during the game. On the game day, the class is divided into teams of five people. Each team wears a different color vest and is called by the color of the vest they are wearing. The starting point is drawn as far as possible from the periodical table. Furthermore, some question cards that cover the subject are used in the game. As an example from the game: one student from each team is asked to find the correct place by the atomic number of a certain element as described in the cards given to them. There is a time limit so the stopwatch is started as each student starts reading the information on the card. The student runs to the correct place of the certain element according to the clues on their given card. Then they stop and raise their hands. The teacher stops the stopwatch for that student. The teams gain points according to their speed and correct guesses. The game continues as other students are given different

    Full Text Available The purpose of this research was to study the influence of motivational climate perceived in peers and basic psychological needs (competence, autonomy and relatedness on self-determined motivation and enjoyment in exercise. A sample comprised of 394 non- competitive physical exercisers, 156 women and 238 men aged between 16 and 54 (M = 21.64, SD = 7. 18, completed the Motivational Climate Perceived in Peers Scale, Scale of Motivational Mediators in Physical Activity, Behavioural Regulation in Exercise Questionnaire-2 and Physical Activity Enjoyment Scale. A correlation analysis between the variables studied, a confirmatory factor analysis (CFA and structural equation analysis were performed. The results showed that the task- involving peer motivational climate positively predicted the three basic psychological needs (competence, autonomy and relatedness. In turn, meeting the needs for competence and relatedness positively predicted self-determined motivation, which also positively predicted the enjoyment the exercisers had during the activity. There were no significant associations between the ego- involving peer motivational climate and psychological needs. A multisample analysis indicated that the model was invariant across age and degree of exercise involvement. This study reiterates the importance of increasing exercisers' self-determined motivation in order to obtain more enjoyment and to be more committed to the exercise. Therefore, it is essential to foster perceptions of competence, autonomy and relatedness by means of a task-involving climate. The findings provide evidence for the importance of peer motivational climate in sports motivation

    Full Text Available Purpose: The present study reflects the economic and financial analysis of  private hospitals with non-charitable character in Catalonia 2008-2013. The private health sector is considered to be a service activity that develops an important social role. The study positions these analysed centers in the Catalan and Spanish health sector and presents the main economic and financial indicators to diagnose the situation of these companies during the period indicated by analysing short and long-term results and analysis of changes in equity and cash flows of the wineries. Design/methodology/approach: The data used comes from the statements of the Catalan hospital centers in the period 2008-2013 and in particular, it contains a sample of 94 Catalan private hospitals, that mostly are considered large-level accounting (according to the General Accounting Plan. The economic and financial  analysis has carried out using descriptive statistics and analysis results and conclusions have been reached. Findings: The study noted that enables private hospitals in this period have a healthy economic and financial status, although it should improve the management of assets. Most sales are concentrated with a small number of hospitals and, regarding the evolution of the results, produces two distinct stages, the first period of decrease (2008-2010 and the second period of growth and recovery from 2011.. Research limitations/implications: It would be desirable to perform the same study by the Spanish private hospitals in order to compare the economic and financial analysis of the Catalan private sector with the Spanish private sector. Practical implications: It allows us to assess the projection of this sector in recent years in Catalonia in order to take the appropriate economic decisions in this regard. Social implications: The results show the changes that have occurred over the years in the economic crisis of the period analysed. Originality / value: For

    Cochlear implantation is associated with poor music perception and enjoyment. Reducing music complexity has been shown to enhance music enjoyment in cochlear implant (CI) recipients. In this study, we assess the impact of harmonic series reduction on music enjoyment. Prospective analysis of music enjoyment in normal-hearing (NH) individuals and CI recipients. Single tertiary academic medical center. NH adults (N = 20) and CI users (N = 8) rated the Happy Birthday song on three validated enjoyment modalities-musicality, pleasantness, and naturalness. Subjective rating of music excerpts. Participants listened to seven different instruments play the melody, each with five levels of harmonic reduction (Full, F3+F2+F1+F0, F2+F1+F0, F1+F0, F0). NH participants listened to the segments both with and without CI simulation. Linear mixed effect models (LME) and likelihood ratio tests were used to assess the impact of harmonic reduction on enjoyment. NH listeners without simulation rated segments with the first four harmonics (F3+F2+F1+F0) most pleasant and natural (p <0.001, p = 0.004). NH listeners with simulation rated the first harmonic alone (F0) most pleasant and natural (p <0.001, p = 0.003). Their ratings demonstrated a positive linear relationship between harmonic reduction and both pleasantness (slope estimate = 0.030, SE = 0.004, p <0.001, LME) and naturalness (slope estimate = 0.012, SE = 0.003, p = 0.003, LME). CI recipients also found the first harmonic alone (F0) to be most pleasant (p = 0.003), with a positive linear relationship between harmonic reduction and pleasantness (slope estimate = 0.029, SE = 0.008, p <0.001, LME). Harmonic series reduction increases music enjoyment in CI and NH individuals with or without CI simulation. Therefore, minimization of the harmonics may be a useful strategy for enhancing musical enjoyment among both NH and CI listeners.

    In light of recent literature in educational psychology, this study investigates instructional support and students' autonomy at a small technical undergraduate school. Grounded theory is used to analyze twelve semi-structured open-ended interviews about engineering students' experiences in Introductory Mechanics that includes Lecture, Recitation, and Laboratory components. Using data triangulation with each course component as a unit of analysis, this study examines students' course enjoyment as a function of instructional support and autonomy. The Lecture utilizes traditional instructor-centered pedagogy with predominantly passive learning and no student autonomy. The Recitation creates an active learning environment through small group work with a moderate degree of autonomy. The Laboratory is designed around self-guided project-based activities with significant autonomy. Despite these differences, all three course components provide similar levels of instructional support. The data reveal that students enjoy the low autonomy provided by Lecture and Recitations while finding the Laboratory frustrating. Analyses indicate that the differences in autonomy contribute to students' misinterpretation of the three course components' value within the context of the entire course.

  7. PSA Level 2 activities for RBMK reactors

    1998-01-01

    Probabilistic safety analyses (PSAs) of the boiling water graphite moderated pressure tube reactors (RBMKs) have been developed only recently and they are limited to Level 1. Activities at the IAEA were first motivated because of the difficulties to characterize core damage for RBMK reactors. Core damage probability is used in documents of the IAEA as a convenient single valued measure, for example for probabilistic safety criteria. The limited number of PSAs that have been completed for the RBMK reactors have shown that several special features of these channel type reactors necessitate revisiting of the characterization of core damage for these reactors. Furthermore, it has become increasingly evident that detailed deterministic analysis of DBAs and beyond design basis accidents reveal considerable insights into RBMK response to various accident conditions. These analyses can also help in better characterizing the outstanding phenomenological uncertainties, improved EOPs and AM strategies, including potential risk-beneficial accident negative backfits. The deterministic efforts should be focused first on elucidating accident progression processes and phenomena, and second on finding, qualifying and implementing procedures to minimize the risk of severe accident states The IAEA PSA procedures were mainly developed in New of vessel type LWRs, and would therefore require extensions to make them directly applicable. to channel type reactors.

    Exercise adherence is affected by factors including perceptions of enjoyment, time availability, and intrinsic motivation. Approximately 50% of individuals withdraw from an exercise program within the first 6 mo of initiation, citing lack of time as a main influence. Time efficient exercise such as high intensity interval training (HIIT) may provide an alternative to moderate intensity continuous exercise (MICT) to elicit substantial health benefits. This study examined differences in enjoyment, affect, and perceived exertion between MICT and HIIT. Twelve recreationally active men and women (age = 29.5 ± 10.7 yr, VO2max = 41.4 ± 4.1 mL/kg/min, BMI = 23.1 ± 2.1 kg/m2) initially performed a VO2max test on a cycle ergometer to determine appropriate workloads for subsequent exercise bouts. Each subject returned for two additional exercise trials, performing either HIIT (eight 1 min bouts of cycling at 85% maximal workload (Wmax) with 1 min of active recovery between bouts) or MICT (20 min of cycling at 45% Wmax) in randomized order. During exercise, rating of perceived exertion (RPE), affect, and blood lactate concentration (BLa) were measured. Additionally, the Physical Activity Enjoyment Scale (PACES) was completed after exercise. Results showed higher enjoyment (p = 0.013) in response to HIIT (103.8 ± 9.4) versus MICT (84.2 ± 19.1). Eleven of 12 participants (92%) preferred HIIT to MICT. However, affect was lower (pHIIT versus MICT. Although HIIT is more physically demanding than MICT, individuals report greater enjoyment due to its time efficiency and constantly changing stimulus. Trial Registration: NCT:02981667.

    Full Text Available Exercise adherence is affected by factors including perceptions of enjoyment, time availability, and intrinsic motivation. Approximately 50% of individuals withdraw from an exercise program within the first 6 mo of initiation, citing lack of time as a main influence. Time efficient exercise such as high intensity interval training (HIIT may provide an alternative to moderate intensity continuous exercise (MICT to elicit substantial health benefits. This study examined differences in enjoyment, affect, and perceived exertion between MICT and HIIT. Twelve recreationally active men and women (age = 29.5 ± 10.7 yr, VO2max = 41.4 ± 4.1 mL/kg/min, BMI = 23.1 ± 2.1 kg/m2 initially performed a VO2max test on a cycle ergometer to determine appropriate workloads for subsequent exercise bouts. Each subject returned for two additional exercise trials, performing either HIIT (eight 1 min bouts of cycling at 85% maximal workload (Wmax with 1 min of active recovery between bouts or MICT (20 min of cycling at 45% Wmax in randomized order. During exercise, rating of perceived exertion (RPE, affect, and blood lactate concentration (BLa were measured. Additionally, the Physical Activity Enjoyment Scale (PACES was completed after exercise. Results showed higher enjoyment (p = 0.013 in response to HIIT (103.8 ± 9.4 versus MICT (84.2 ± 19.1. Eleven of 12 participants (92% preferred HIIT to MICT. However, affect was lower (p<0.05 and HR, RPE, and BLa were higher (p<0.05 in HIIT versus MICT. Although HIIT is more physically demanding than MICT, individuals report greater enjoyment due to its time efficiency and constantly changing stimulus.NCT:02981667.

  10. Dance-Based ExerGaming: User Experience Design Implications for Maximizing Health Benefits Based on Exercise Intensity and Perceived Enjoyment

    Science.gov (United States)

    Thin, Alasdair G.; Poole, Nicola

    Dance is a form of exercise that is considered to have widespread popular appeal and in particular to adolescent females. Dance-based body-movement controlled video games are a popular form of ExerGaming that is being adopted for use in school-based physical activity health promotion programs. The results of this study indicate that the game play mechanics and skill demands of the dance-based ExerGames would appear to have limited the subjects' level of physical exertion over the period of study. After training there was an increase in enjoyment rating for the Step Aerobics game which appears related to a perceptible improvement in game performance. It is therefore recommended that ExerGames should be designed with very low initial skill demands in order to maximize the user's level of exertion and to realize and reward progress, thereby helping to promote an enjoyable exercise experience and counterbalance any sense of exertional discomfort. Keywords: exercise; health promotion; exergaming; user experience; design; video game; enjoyment.

    This study aimed to evaluate determinants of differences in leisure reading behavior and school achievement. We specifically examined reading enjoyment, mental imagery, and sex as predictors in a large, age-homogeneous sample of Dutch secondary school students (N = 1,071). Results showed that the prevalence of leisure reading was low in both the lower, pre-vocational track (19.5%) and the higher, pre-academic track (32.5%). Boys read even less than girls. Almost all leisure readers enjoyed reading and engaged in mental imagery, i.e., the propensity "to see images" of a written story in the mind's eye. Overall, boys who did not like to read for leisure had the poorest school performance. Non-leisure readers who reported that they enjoyed reading got higher school grades in the higher educational track. In the lower track, this was the case for girls. Our study findings imply that reading promotion programs should take into account individual differences in sex, achievement level, and reading enjoyment when aiming to decrease the academic achievement gap.

    Although physical activity reduces the risk of diseases such as cancer, diabetes and cardiovascular disease, a large proportion of the population is not sufficiently physically active. Therefore, the present study examined the environmental, social, and psychological correlates for meeting the 2 recommended physical activity criteria: ≥420 min per week of at least moderate-intensity activity (MPA criterion) and ≥210 min per week of vigorous activity (VPA criterion) for colon cancer prevention among Japanese adults. Cross-sectional study. The sample included 2000 Japanese adults aged 20-79 years. An Internet-based survey was used to assess seven sociodemographic variables (e.g., education level, employment status), environmental variables (home fitness equipment, access to facilities, neighborhood safety, aesthetic sensibilities, and frequency of observing others exercising, residential area), social variables (social support), psychological variables (self-efficacy, perceived positive (pros) and negative (cons) aspects of exercise), and physical activity. The adjusted odds of meeting each physical activity criterion by these variables were calculated. Overall, 22.3% of the study population met the criterion of MPA, and 7.3% met the criterion of VPA. Having high self-efficacy, fewer perceived cons, possessing home fitness equipment, reporting enjoyable scenery, and living in a rural area were significantly associated with meeting the recommended criteria. Participants who met the 2 activity recommendations differed by self-efficacy, cons, possession of home fitness equipment, reporting of enjoyable scenery, and residential area. These findings imply that strategies to promote more intense physical activities specifically in terms of these variables may be necessary for colon cancer prevention. Crown Copyright © 2013.

    2017-08-01

    This study reports results of a study that examined the extent to which contextual factors (i.e., income level and number of children) might predict a mother's mental health quality, which, in turn, may predict level of engagement with Facebook. Results supported this model, finding that mothers with more children and lower income possess lower mental health quality, and lower mental health quality predicted more frequent Facebook use. However, this pattern was qualified by a mother's level of enjoyment of Facebook, such that mental health quality did not significantly predict Facebook intensity when enjoyment of Facebook was low. This research extends practitioners' knowledge of mothers' mental health quality by identifying a behavior that may indicate lower mental health quality and enhance abilities to recognize mothers who may need support or treatment. Future directions for this research are included.

  15. Enjoy your food: on losing weight and taking pleasure.

    2014-02-01

    Does healthy eating require people to control themselves and abstain from pleasure? This idea is dominant, but in our studies of dieting in The Netherlands we encountered professionals who work in other ways. They encourage their clients to enjoy their food, as only such joy provides satisfaction and the sense that one has eaten enough. Enjoying one's food is not easy. It depends on being sensitive. This does not come naturally but needs training. And while one kind of hunger may be difficult to distinguish from another, feeling pleasure may open the doors to feeling pain. What is more, sensitivity is not enough: enjoying one's food also depends on the food being enjoyable. A lot of care is required for that. But while engaging in such care is hard work, along the way clients are encouraged to no longer ask 'Am I being good?' but to wonder instead 'Is this good for me?' Both these questions are normative and focus on the person rather than on her socio-material context. However, in the situations related here the difference is worth making. For it entails a shift from externally controlling your behaviour to self-caringly enjoying your food. © 2014 The Authors.

    Building upon Deci's and Ryan (1985) Self-determination theory as well as the sportive behavioral correlates of the model of Commitment (Scanlan et al., 1976), this study tries to establish the relationship between motivation and commitment in youth sport. For this purpose 454 young competitive soccer players answered the Sport Motivation Scale (SMS) and the Sport Commitment Questionnaire (SCQ) during the regular season. The SMS measures the three dimensions of the Motivational continuum (the Amotivation, the Extrinsic Motivation and the Intrinsic Motivation). The SCQ measures the Sportive Commitment and its composing factors such as the Enjoyment, the Alternatives to the sport, and the Social Pressure. Our findings provided a clear pattern of the influence of motivation in sport enjoyment and commitment, outlining the positive contribution of intrinsic and extrinsic motivation to enjoyment and commitment. Amotivation, contributes positively to alternatives to sport and negatively to enjoyment and commitment, It should be noted that extrinsic motivation has a higher contribution to enjoyment whereas intrinsic motivation has a higher contribution to commitment.

    Full Text Available This study explores Ghanaian women’s perception and voices about issues of gender equality in terms of exercising their political and decision-making rights in connection with political participation and governance in Ghana. The study uses demographic survey and six different focus group discussions to capture the views of a total of 68 women with different educational, socioeconomical, and occupational backgrounds, in two regions of the Ghana. The findings indicate that even though theoretically the constitution of Ghana gives women equal rights as their male counterparts to actively participate in the governance of their country, in practice, women face issues of gender-based power imbalance and discrimination in addition to other structural, institutional, cultural, and traditional barriers and roadblocks. These barriers expose women as being inferior and second-class citizens compared with their male counterparts in term of participation and inclusion in the governance of their country. The study discusses the social and policy implications of the issues of gender inequality and social exclusion of women in politics and calls for empowerment and organization of women and structural change in the system.

    To examine if gardening experience and enjoyment are associated with vegetable exposure, preferences, and consumption of vegetables among low-income third-grade children. Cross-sectional study design, using baseline data from the Texas! Grow! Eat! Go! Twenty-eight Title I elementary schools located in different counties in Texas. Third-grade students (n = 1,326, 42% Hispanic) MAIN OUTCOME MEASURES: Gardening experience, gardening enjoyment, vegetable exposure, preference, and consumption. Random-effects regression models, adjusted for age, sex, ethnicity, and body mass index percentile of child, estimated means and standard errors of vegetable consumption, exposure, and preference by levels of gardening experience and enjoyment. Wald χ 2 tests evaluated the significance of differences in means of outcomes across levels of gardening experience and enjoyment. Children with more gardening experience had greater vegetable exposure and higher vegetable preference and consumed more vegetables compared with children who reported less gardening experience. Those who reported that they enjoyed gardening had the highest levels of vegetable exposure, preference, and consumption. Garden-based interventions can have an important and positive effect on children's vegetable consumption by increasing exposure to fun gardening experiences.

    Super-leadership is part of an approach called 'empowering leadership.' Within this approach, super-leadership is assumed to enable subordinates to lead themselves. The current study examined correlates of super-leadership. A questionnaire measuring two dimensions of super-leadership was used to analyze relationships between super-leadership and subordinates' work enjoyment, i.e., job satisfaction, subjective well-being, and emotional organizational commitment. In addition, moderating effects of the organizational context, i.e., organizational decentralization, on the relationships between super-leadership and work enjoyment were explored. 198 German employees from different occupations participated in the study. Latent moderator structural equation analysis revealed that the two factors of super-leadership, "coaching and communicative support" and "facilitation of personal autonomy and responsibility," had direct positive effects on subordinates' work enjoyment. Organizational decentralization moderated the effect of "coaching and communicative support" on work enjoyment but not the relations involving "facilitation of personal autonomy and responsibility." Conclusions for further research and practical applications were discussed.

    Active videogames (AVGs) that require body movements to play offer a novel opportunity to turn a traditionally sedentary behavior into a physically active one. We sought to determine the effect of a school-based AVG intervention on Chinese children's aerobic fitness, physical activity (PA) level, and PA-related psychological correlates. Eighty 8-11-year-old Chinese children (55 males) were recruited from one Hong Kong primary school and were allocated at random to either an AVG intervention or control group. Children in the intervention group played an AVG, Xbox 360, twice per week during after-school hours, each for 60 minutes over 12 weeks in duration. The control group received no intervention. Children's body-mass index (BMI), objective PA, aerobic fitness (maximum oxygen consumption [VO 2max ]), PA task efficacy, barrier efficacy, and enjoyment were assessed. Compared with the control group, significant increases were found in the intervention group in VO 2max [mean and 95% confidence interval (CI): 1.58 (0.74, 2.42) mL/(kg·min)], objective moderate-to-vigorous PA [6.73 (1.70, 11.76) min/day], and total PA [27.19 (9.33, 45.04) min/day], but not for BMI. No significant differences in PA task efficacy, barrier efficacy, and enjoyment were observed. A 12-week (60 minutes × twice per week) school-based AVG intervention can improve Chinese children's aerobic fitness and PA level. These findings indicated that AVGs could be used as an alternative means to engage Chinese children in PA in school setting. However, the treatment effects of AVGs on PA-related psychological correlates and body composition need more investigation.

    Past research into exercise among people with long-term health conditions has paid surprisingly little attention to the concept of enjoyment. This study explored enjoyment of exercise among people with arthritis. Semi-structured interviews were held with 12 participants aged 20-85 years. The transcripts were analysed using inductive thematic analysis. Four themes were identified: enjoyment of exercise in relation to other people, benefits of exercise in relation to enjoyment, working around barriers to enjoy exercise and finding an enjoyable balance to exercise. These themes highlight the relevance of enjoyment and how it could feature in advice about exercise for people with arthritis.

  9. It's not how much you play, but how much you enjoy the game: the longitudinal associations between adolescents' self-esteem and the frequency versus enjoyment of involvement in sports.

    2014-01-01

    The frequency of involvement in sports often has been concurrently and longitudinally associated with higher self-esteem. The interpretation of this association consistently has been framed as involvement in sports leading to higher levels of self-esteem over time (i.e., socialization effect), although no studies have tested whether higher levels of self-esteem lead to increased involvement in sports over time (i.e., selection effect). Another important aspect of involvement in sports that may be related to self-esteem is the degree to which youth enjoy sports. However, this aspect has received much less attention. To address these gaps in the literature, we first examined the bidirectional effects between self-esteem and the frequency of involvement in sports with 1,492 adolescents (50.8 % female; 92.4 % Canadian-born) over 4 years. Higher levels of self-esteem predicted greater involvement in sports over time, but greater involvement in sports did not predict higher levels of self-esteem over time, offering support only for selection effects. We then tested the bidirectional effects between the enjoyment of sports and self-esteem and found evidence of both socialization and selection effects. Specifically, greater enjoyment of sports predicted higher self-esteem over time, and higher self-esteem predicted greater enjoyment of sports over time. These novel findings suggest that adolescents with higher self-esteem play sports more frequently and enjoy sports more than adolescents with lower self-esteem. In addition, the degree to which adolescents enjoy sports may be more important for increasing self-esteem than the frequency with which adolescents play sports.

  10. Platelets retain high levels of active plasminogen activator inhibitor 1.

    Directory of Open Access Journals (Sweden)

    Helén Brogren

    Full Text Available The vascular fibrinolytic system is crucial for spontaneous lysis of blood clots. Plasminogen activator inhibitor 1 (PAI-1, the principal inhibitor of the key fibrinolytic enzyme tissue-type plasminogen activator (tPA, is present in platelets at high concentrations. However, the majority of PAI-1 stored in platelets has been considered to be inactive. Our recent finding (Brogren H, et al. Blood 2004 that PAI-1 de novo synthesized in platelets remained active for over 24 h, suggested that PAI-1 stored in the α-granules might be active to a larger extent than previously reported. To re-evaluate this issue, we performed experiments where the fraction of active PAI-1 was estimated by analyzing the tPA-PAI-1 complex formation. In these experiments platelets were lysed with Triton X-100 in the presence of serial dilutions of tPA and subsequently the tPA-PAI-1 complex was evaluated by Western blot. Also, using a non-immunologic assay, tPA was labeled with (125I, and (125I-tPA and (125I-tPA-PAI-1 was quantified by scintigraphy. Interestingly, both methods demonstrated that the majority (>50% of platelet PAI-1 is active. Further analyses suggested that pre-analytical procedures used in previous studies (sonication or freezing/thawing may have substantially reduced the activity of platelet PAI-1, which has lead to an underestimation of the proportion of active PAI-1. Our in vitro results are more compatible with the role of PAI-1 in clot stabilization as demonstrated in physiological and pathophysiological studies.

    2018-01-01

    Full Text Available In this paper, a parallel analysis of the enjoyment derived from humor and insight problem solving is presented with reference to a “general” Theory of the Pleasures of the Mind (TPM (Kubovy, 1999 rather than to “local” theories regarding what makes humor and insight problem solving enjoyable. The similarity of these two cognitive activities has already been discussed in previous literature in terms of the cognitive mechanisms which underpin getting a joke or having an insight experience in a problem solving task. The paper explores whether we can learn something new about the similarities and differences between humor and problem solving by means of an investigation of what makes them pleasurable. In the first part of the paper, the framework for this joint analysis is set. Two descriptive studies are then presented in which the participants were asked to report on their experiences relating to solving visuo-spatial insight problems (Study 1 or understanding cartoons (Study 2 in terms of whether they were enjoyable or otherwise. In both studies, the responses were analyzed with reference to a set of categories inspired by the TPM. The results of Study 1 demonstrate that finding the solution to a problem is associated with a positive evaluation, and the most frequent explanations for this were reported as being Curiosity, Virtuosity and Violation of expectations. The results of Study 2 suggest that understanding a joke (Joy of verification and being surprised by it (Feeling of surprise were two essential conditions: when they were not present, the cartoons were perceived as not enjoyable. However, this was not enough to explain the motivations for the choice of the most enjoyable cartoons. Recognizing a Violation of expectations and experiencing a Diminishment in the cleverness or awareness initially attributed to the characters in the cartoon were the aspects which were most frequently indicated by the participants to explain why they

    High intensity interval training (HIIT) is a robust and time-efficient approach to improve multiple health indices including maximal oxygen uptake (VO 2 max). Despite the intense nature of HIIT, data in untrained adults report greater enjoyment of HIIT versus continuous exercise (CEX). However, this has yet to be investigated in persons with spinal cord injury (SCI). To examine differences in enjoyment in response to CEX and HIIT in persons with SCI. Repeated measures, within-subjects design. University laboratory in San Diego, CA. Nine habitually active men and women (age = 33.3 ± 10.5 years) with chronic SCI. Participants performed progressive arm ergometry to volitional exhaustion to determine VO 2 peak. During subsequent sessions, they completed CEX, sprint interval training (SIT), or HIIT in randomized order. Physical activity enjoyment (PACES), affect, rating of perceived exertion (RPE), VO 2 , and blood lactate concentration (BLa) were measured. Despite a higher VO 2 , RPE, and BLa consequent with HIIT and SIT (P HIIT (107.4 ± 13.4) and SIT (103.7 ± 12.5) compared to CEX (81.6 ± 25.4). Fifty-five percent of participants preferred HIIT and 45% preferred SIT, with none identifying CEX as their preferred exercise mode. Compared to CEX, brief sessions of submaximal or supramaximal interval training elicit higher enjoyment despite higher metabolic strain. The long-term efficacy and feasibility of HIIT in this population should be explored considering that it is not viewed as more aversive than CEX.

    Doctors' job satisfaction is important to the health service to ensure commitment, effective training, service provision and retention. Job satisfaction matters to doctors for their personal happiness, fulfilment, service to patients and duty to employers. Monitoring job satisfaction trends informs workforce planning. We surveyed UK-trained doctors up to 5 years after graduation for six graduation year cohorts: 1996, 1999, 2002, 2005, 2008, 2012. Doctors scored their job enjoyment (Enjoyment) and satisfaction with time outside work (Leisure) on a scale from 1 (lowest enjoyment/satisfaction) to 10 (highest). Overall, 47% had a high level of Enjoyment (scores 8-10) 1 year after graduation and 56% after 5 years. For Leisure, the corresponding figures were 19% and 37% at 1 and 5 years, respectively. For Leisure at 1 year, high scores were given by about 10% in the 1990s, rising to about 25% in the mid-2000s. Low scores (1-3) for Enjoyment were given by 15% of qualifiers of 1996, falling to 5% by 2008; corresponding figures for Leisure were 42% and 19%. At 5 years, the corresponding figures were 6% and 4%, and 23% and 17%. Enjoyment and Leisure were scored higher by general practitioners than doctors in other specialties. Both measures varied little by sex, ethnicity or medical school attended. Scores for Enjoyment were generally high; those for Leisure were lower. Policy initiatives should address why this aspect of satisfaction is low, particularly in the first year after graduation but also among hospital doctors 5 years after graduation.

    Some human behaviors, including aggression and activity level, differ on average for males and females. Here we report findings from two studies investigating possible relations between prenatal androgen and children's aggression and activity level. For study 1, aggression and activity level scores for 43 girls and 38 boys, aged 4 to 11years, with congenital adrenal hyperplasia (CAH, a genetic condition causing increased adrenal androgen production beginning prenatally) were compared to those of similarly-aged, unaffected relatives (41 girls, 31 boys). Girls with CAH scored higher on aggression than unaffected girls, d=0.69, and unaffected boys scored higher on activity level than unaffected girls, d=0.50. No other group differences were significant. For study 2, the relationship of amniotic fluid testosterone to aggression and activity level was investigated in typically-developing children (48 girls, 44 boys), aged 3 to 5years. Boys scored higher than girls on aggression, d=0.41, and activity level, d=0.50. However, amniotic fluid testosterone was not a significant predictor of aggression or activity level for either sex. The results of the two studies provide some support for an influence of prenatal androgen exposure on children's aggressive behavior, but not activity level. The within-sex variation in amniotic fluid testosterone may not be sufficient to allow reliable assessment of relations to aggression or activity level. Copyright © 2017 Elsevier Inc.

    Badminton has been identified as a lifelong activity. It is an inexpensive sport and everyone--children, seniors, and individuals with disabilities--can reach a level of enjoyment in the game after mastering basic skills and tactics. In teaching badminton, teachers need to understand how students develop game play ability from a low level to an…

  16. Cultivating Engagement and Enjoyment in Exergames Using Feedback, Challenge, and Rewards.

    Lyons, Elizabeth J

    2015-02-01

    This article reviews theoretical and empirical evidence related to three mechanisms for encouraging enjoyment during exergame play: Feedback, challenge, and rewards. A literature search and narrative review were conducted. Feedback is found in nearly all exergames, and richer, more in-depth feedback is associated with increased activity. Challenge is a vital component of any videogame, and exergames include physical as well as cognitive challenges. Flow states have traditionally been conceptualized as occurring when an optimal match between player skills and game challenge occurs. However, failure and retrial are necessary for feelings of overall satisfaction and fun, despite not necessarily being ideally fun or satisfying themselves. Rewards are a more complicated issue, with significant theoretical and empirical evidence suggesting positive and negative effects of reward systems. How rewards are integrated into the mechanics and storyline of the game likely impacts how they are perceived and, thus, their effectiveness. Finally, integration of these mechanisms into exergames requires specific attention to both cognitive and physical implementations. Movements that are not themselves enjoyable or engaging may lead to cheating and lower energy expenditure. Feedback, challenge, and rewards are promising mechanisms by which exergames could become more enjoyable. How these concepts are operationalized can affect physical and psychological reactions to exergames. Attention to these concepts in future exergame development and implementation would benefit theory, research, and practice.

    An unhealthy lifestyle can increase the risk of cardiovascular disease. However, the mechanism by which lifestyle influences the development of cardiovascular disease remains unclear. Since coronary endothelial function is a predictor of cardiovascular prognosis, the goal of this study was to characterize the effect of enjoying hobbies on coronary endothelial function and cardiovascular outcomes. A total of 121 consecutive patients (76 men, 45 women) with almost normal coronary arteries underwent Doppler flow study of the left anterior descending coronary artery following sequential administration of papaverine, acetylcholine, and nitroglycerin. On the basis of responses to questionnaires, patients were divided into two groups; the Hobby group (n = 71) who enjoyed hobbies, and the Non-hobby group (n = 50) who had no hobbies. Cardiovascular outcomes were assessed at long-term follow-up using medical records or questionnaire surveys for major adverse cardiovascular events (MACE).The average follow-up period was 916 +/- 515 days. There were no significant differences in demographics when comparing the two groups. The percent change in coronary blood flow and coronary artery diameter induced by acetylcholine was significantly greater in the Hobby group than in the Non-hobby group (49% +/- 77% vs 25% +/- 37%, P hobbies was the only independent predictor of MACE (odds ratio 8.1 [95% confidence interval 1.60, 41.90], P = 0.01) among the variables tested. In the early stages of arteriosclerosis, enjoying hobbies may improve cardiovascular outcomes via its favorable effects on coronary endothelial function.

    Full Text Available Emotions are a fleeting experience, sometimes lasting only moments before dissipating. Prior research in SLA has either ignored emotions, underestimated their relevance, or has studied them as a relatively stable individual difference variable. In contrast, the present study takes an idiodynamic approach to examine the rapidly changing relationship between enjoyment and anxiety in second language communication, on a moment-to-moment timescale. University students who speak French as a second language were recruited to complete oral tasks in their second language. Participants then rated their per-second fluctuations in each emotion while watching a video recording of their tasks. Immediately after this, they were interviewed about their attributions for fluctuations in their ratings. We found that the relationship between enjoyment and anxiety is highly dynamic, resulting in varying patterns of correlation ranging from negative to positive. Triangulation of ratings of anxiety and enjoyment with interview data produces a richer understanding of the role of emotions in second language communication.

    Enjoyment is consistently noted as important for engaging audiences in games for health. However, as a term, enjoyment is often used interchangeably with a host of other terms, some of which overlap conceptually. This obscures what does and what does not constitute enjoyment, and in turn slows scientific progress by making the study of enjoyment and the synthesis of enjoyment-related research difficult. This article is aimed at improving our understanding of enjoyment by distinguishing enjoyment from other important constructs, such as fun and engagement, and by providing an overview of the experimental evidence on the determinants of enjoyment in videogames. Competence, narrative transportation, and relevance are identified as key factors related to enjoyment, and future studies examining these factors using games for health are recommended.

    Technoeconomic paradigms based economic growth theories suggest that waves of technological innovations drove the economic growth of advanced economies. Widespread economic degradation and pollution is an unintended consequence of such growth. Tackling environmental and social issues at firm levels would help us to overcome such issues at macro-levels. Consequently, the Triple Bottom Line (TBL) reporting approach promotes firm level economic, environmental and social performances. Incorporating Zink's (2014) 3-pillar presentation model, this paper indicates that economic, social and environmental performances tend to be reported at firm level. All three pillars are not covered evenly at the activity levels. Thus, a loophole is identified whereby excellent environmental performance at activity levels could potentially leave poor social performance undisclosed. A refinement of the TBL paradigm, whereby all three pillars are covered at the activity level, is suggested, to enhance sustainability reporting. Copyright © 2016 Elsevier Ltd. All rights reserved.

    The nature of human-human interaction, specifically, how people synchronize with each other in multiple-participant conversations, is described by a ferromagnetic interaction model of people’s activity levels. We found two microscopic human interaction characteristics from a real-environment face-to-face conversation. The first characteristic is that people quite regularly synchronize their activity level with that of the other participants in a conversation. The second characteristic is that the degree of synchronization increases as the number of participants increases. Based on these microscopic ferromagnetic characteristics, a “conversation activity level” was modeled according to the Ising model. The results of a simulation of activity level based on this model well reproduce macroscopic experimental measurements of activity level. This model will give a new insight into how people interact with each other in a conversation.

    The purpose of this study was to compare women's levels of physical activity during early pregnancy and during the year before pregnancy, and to identify characteristics associated with discontinuing sports and exercise among women previously active during the year before pregnancy. Data collected from 1,737 women enrolled in a prospective cohort study and who had no contraindications for exercise were included in this analysis. Measures of physical activity (including household and care-giving activities, active living and sports and exercise activities) during early pregnancy were compared to the year before pregnancy. Log binomial regression was used to identify factors associated with discontinuing sports and exercise during pregnancy. There was a statistically significant decrease in all summary measures of physical activity during early pregnancy. The largest decreases were observed in sports and exercise activity. Among women active before pregnancy, age pregnancy body mass index (BMI) > or = 30 kg/m(2) and lower levels of pre-pregnancy exercise were associated with discontinuing sports and exercise activities during pregnancy. Most women reduced their physical activity level during the first 20 weeks of pregnancy compared with their level of activity during the year prior to pregnancy, particularly for sports and exercise, although a small proportion of women in this study actually increased their activity in this area during early pregnancy. Participation in sports and exercise activity during pregnancy is potentially modifiable and could favorably impact perinatal health and maternal post-partum weight. The results of this study suggests that pregnancy is an event that leads to a decrease in physical activity.

    To examine participation-preference congruence, regional differences in participation-preference congruence, and predictors of whether children with cerebral palsy participate in preferred activities. The sample (n=236) included 148 males and 88 females aged 10 to 13 years, living in Victoria, Australia (n=110), Ontario (n=80), or Quebec (n=46), Canada. Ninety-nine (41.9%) were classed at Gross Motor Function Classification System (GMFCS) level I; 89 (37.7%) at GMFCS level II/III; and 48 (20.3%) at GMFCS level IV/V. Participants completed the Children's Assessment of Participation and Enjoyment and Preferences for Activity of Children questionnaires. Regional comparisons were performed using one-way analyses of variance and factors influencing participation-preference congruence were explored using multiple linear regression. The proportion of children doing non-preferred activities in each activity type was generally low (2-17%), with only one regional difference. Higher proportions were not doing preferred active physical (range 23.2-29.1% across regions), skill-based (range 21.7-27.9% across regions), and social activities (range 12.8-14.5% across regions). GMFCS level was the most important predictor associated with not doing preferred activities. Children with cerebral palsy did not always participate in preferred active physical and skill-based activities. Understanding discrepancies between preferences and actual involvement may allow families and rehabilitation professionals to address participation barriers. © 2016 Mac Keith Press.

    NEEDs for Bones (NFB), based on the Health Belief Model, is a 4-lesson osteoporosis-prevention curriculum for 11- to 14-year-olds. This study examined the relationship between enjoyment of food tastings and interest in NFB. NFB was administered by teachers as part of standard practice and evaluated after the fourth lesson using a 21-item survey. Significant clustering of students within classrooms required use of random-intercept multilevel ordinal regression models in SAS proc GLIMMIX, with students nested within classrooms. Analyses considered tasting experience, eating attitudes, sex, grade, and cohort. Students (N = 1619; 50% girls) participated from 85 fourth to eighth grade classrooms (47% sixth grade and 31% seventh grade) in 16 Pennsylvania SNAP-Ed eligible schools over 2 academic years. For all foods tasted, students who did not enjoy the food tasting were less interested in the lesson than students who did enjoy the food tasting (all p < .001); refried beans (odds ratio [OR] = 0.30), soy milk (OR = 0.55), cranapple juice (OR = 0.51), sunflower kernels (OR = 0.48), and Swiss cheese (OR = 0.49). The relationship persisted net of covariates. Enjoyment of food tasting activities can predict interest in nutrition education on osteoporosis prevention, supporting resource allocation and inclusion of food tasting activities in school-age nutrition education. © 2015, American School Health Association.

    The aim of this study was to explore how and why participants in structured exercise intervention programs continue or stop exercising after the program is finished. We conducted four focus group interviews with four groups of middle-aged and elderly men (total n = 28) who had participated in exercise interventions involving playing either a team sport (football) or a more individually focused activity (spinning and crossfit). Our results show that different social, organizational and material structures inherent in the different activities shape the subjects' enjoyment of exercise participation, as well as their intention and ability to continue being active. In conclusion, team sport activities seem to be intrinsically motivating to the participants through positive social interaction and play. They are therefore more likely to result in exercise continuation than activities that rely primarily on extrinsic motivation such as the expectation of improved health and well-being. © 2014 John Wiley & Sons A/S.

    In-hospital trauma team activation criteria are formulated to identify severely injured patients requiring specialized multidisciplinary care. Efficacy of trauma activation (TA) criteria is commonly measured by emergency department (ED) disposition, injury severity score, and mortality. Necessity of critical ED interventions is another measure that has been proposed to evaluate the appropriateness of TA criteria. Two-year retrospective cohort study of 1715 patients from our trauma registry at a Level 1 pediatric trauma center. We abstracted data on acute interventions, level and criterion of TA, ED disposition, and mortality. We report odds ratio (OR) with 95% confidence intervals (CIs), positive predictive value, and frequency of acute interventions. Trauma activation was initiated for 947 (55%) of the 1715 patients. There were 426 ED interventions performed on 235 patients (14%); 67.8% were in level 1 activations; 17.6% in level 2, and 14.6% in level 3. Highest-level activations were highly associated with need for ED interventions (OR, 16.1; 95% CI, 11.5-22.4). The ORs for requiring an ED intervention were low for lower level activations (OR, 0.4; 95% CI, 0.3-0.5), trauma service consults (OR, 0.3; 95% CI, 0.2-0.4), and certain mechanism-based criteria. The ORs for ED intervention for isolated motor vehicle collision (0.2; 95% CI, 0.1-0.7), isolated all-terrain vehicle rollover (0.4; 95% CI, 0.1-1.7), and suspected spinal cord injury (0.5; 95% CI, 0.1-3.7) were significantly lower than 1. Highest-level activation criteria correlate with high utilization of ED resources and interventions. Lower level activation criteria and trauma service consult criteria are not highly correlated with need for ED interventions. Downgrading isolated motor vehicle collision and all-terrain vehicle rollovers and suspected spinal cord injury to lower level activations could decrease the overtriage rate, and adding age-specific bradycardia as a physiologic criterion could improve our

    This study examines the development of video game enjoyment over time. The results of a longitudinal study (N=62) show that enjoyment increases over several sessions. Moreover, results of a multilevel regression model indicate a causal link between the dependent variable video game enjoyment and the predictor variables exploratory behavior, spatial presence, competence, suspense and solution, and simulated experiences of life. These findings are important for video game research because they reveal the antecedents of video game enjoyment in a real-world longitudinal setting. Results are discussed in terms of the dynamics of video game enjoyment under real-world conditions.

Results: (1 The correlation analysis indicates that BMI and impulsivity (r = 0.43 and 0.52 have a significant positive correlation with the sitting time (r = 0.61 and a significant negative correlation with the activity level (r= −0.49. (2 The path analysis indicates that the reward sensitivity directly affects BMI and indirectly affects BMI through the activity level as well; the eating behavior has an insignificantly direct impact on BMI, because its impact is generated by the intermediary role of induced diet. Conclusion: (1 The impulsivity, eating behavior and activity level are closely related to BMI; (2 the activity level, sitting time and induced diet play an intermediary role between the impulsivity and BMI.

Seventeen U-16 male soccer players (age = 15.5 ± 0.6 years, and 8.5 years of experience of a Spanish First Division club academy were randomized to 2 different groups for 6 weeks: SSG group (n = 9 and IT group (n = 8. In addition to the usual technical and tactical sessions and competitive games, the SSG group performed 11 sessions with different SSGs, whereas the IT group performed the same number of sessions of IT. Players were tested before and after the 6-week training intervention with a continuous maximal multistage running field test and the counter movement jump test (CMJ. At the end of the study, players answered the physical activity enjoyment scale (PACES. During the study, heart rate (HR and session perceived effort (sRPE were assessed. SSGs were as effective as IT in maintaining the aerobic fitness in elite young soccer players during the last weeks of the season. Players in the SSG group declared a greater physical enjoyment than IT (P = 0.006; ES = 1.86 ± 1.07. Coaches could use SSG training during the last weeks of the season as an option without fear of losing aerobic fitness while promoting high physical enjoyment.

  2. Serum Renalase Levels Correlate with Disease Activity in Lupus Nephritis.

    Chaojun Qi

    Full Text Available Lupus nephritis (LN is among the most serious complications of systemic lupus erythematosus (SLE, which causes significant morbidity and mortality. Renalase is a novel, kidney-secreted cytokine-like protein that promotes cell survival. Here, we aimed to investigate the relationship of serum renalase levels with LN and its role in the disease progression of LN.For this cross-sectional study, 67 LN patients and 35 healthy controls were enrolled. Seventeen active LN patients who received standard therapies were followed up for six months. Disease activity was determined by the SLE Disease Activity-2000 (SLEDAI-2K scoring system and serum renalase amounts were determined by ELISA. Predictive value of renalase for disease activity was assessed. Furthermore, the expression of renalase in the kidneys of patients and macrophage infiltration was assessed by immunohistochemistry.Serum renalase amounts were significantly higher in LN patients than in healthy controls. Moreover, patients with proliferative LN had more elevated serum renalase levels than Class V LN patients. In proliferative LN patients, serum renalase levels were significantly higher in patients with active LN than those with inactive LN. Serum renalase levels were positively correlated with SLEDAI-2K, 24-h urine protein excretion, ds-DNA and ESR but inversely correlated with serum albumin and C3. Renalase amounts decreased significantly after six-months of standard therapy. The performance of renalase as a marker for diagnosis of active LN was 0.906 with a cutoff value of 66.67 μg/ml. We also observed that the amount of renalase was significantly higher in glomerular of proliferative LN along with the co-expression of macrophages.Serum renalase levels were correlated with disease activity in LN. Serum renalase might serve as a potential indicator for disease activity in LN. The marked increase of glomerular renalase and its association with macrophages suggest that it might play an

    Children learn to fit into society through living in a group, and it's greatly influenced by their friend relations. Although preschool teachers need to observe them to assist in the growth of children's social progress and support the development each child's personality, only experienced teachers can watch over children while providing high-quality guidance. To resolve the problem, this paper proposes a mathematical and objective method that assists teachers with observation. It uses numerical data of activity level recorded by pedometers, and we make tree diagram called dendrogram based on hierarchical clustering with recorded activity level. Also, we calculate children's ``breadth'' and ``depth'' of friend relations by using more than one dendrogram. When we record children's activity level in a certain kindergarten for two months and evaluated the proposed method, the results usually coincide with remarks of teachers about the children.

    The recent surge of interest towards the paradoxical pleasure produced by sad music has generated a handful of theories and an array of empirical explorations on the topic. However, none of these have attempted to weigh the existing evidence in a systematic fashion. The present work puts forward an integrative framework laid out over three levels of explanation - biological, psycho-social, and cultural - to compare and integrate the existing findings in a meaningful way. First, we review the evidence pertinent to experiences of pleasure associated with sad music from the fields of neuroscience, psychophysiology, and endocrinology. Then, the psychological and interpersonal mechanisms underlying the recognition and induction of sadness in the context of music are combined with putative explanations ranging from social surrogacy and nostalgia to feelings of being moved. Finally, we address the cultural aspects of the paradox - the extent to which it is embedded in the Western notion of music as an aesthetic, contemplative object - by synthesising findings from history, ethnography, and empirical studies. Furthermore, we complement these explanations by considering the particularly significant meanings that sadness portrayed in art can evoke in some perceivers. Our central claim is that one cannot attribute the enjoyment of sadness fully to any one of these levels, but to a chain of functionalities afforded by each level. Each explanatory level has several putative explanations and its own shift towards positive valence, but none of them deliver the full transformation from a highly negative experience to a fully enjoyable experience alone. The current evidence within this framework ranges from weak to non-existent at the biological level, moderate at the psychological level, and suggestive at the cultural level. We propose a series of focussed topics for future investigation that would allow to deconstruct the drivers and constraints of the processes leading to

    Full Text Available This study investigated the association between physical activity facilities at childcare (e.g., play equipment and physical activity of 2- and 3-year olds. Observations of physical activity intensity were performed among 175 children at 9 childcare centers in The Netherlands, using the OSRAC-P. The physical activity facilities were assessed for indoors and outdoors separately, using the EPAO instrument. Regular (single-level multivariate and multilevel linear regression analyses examined the association of the facilities and child characteristics (age and sex with children's activity levels. Various physical activity facilities were available in all childcare centers (e.g., balls. Riding toys and a small playing area were associated with lower indoor physical activity levels. Outdoor physical activity levels were positively associated with the availability of portable jumping equipment and the presence of a structured track on the playground. Portable slides, fixed swinging equipment, and sandboxes were negatively associated with outdoor activity levels. In addition, the 3-year old children were more active outdoors than the 2-year olds. In conclusion, not all physical activity facilities at childcare were indeed positively associated with children's activity levels. The current findings provide concrete leads for childcare providers regarding which factors they can improve in the physical environment to facilitate children's physical activity.

    While the flourine level of (drinking) water was higher than normal ranges in the center of Isparta region before 1995 year, this problematic situation is solved in later years. (However) the individuals who are staying in Yenice district are still expose to high levels of fluorine because of the usage of Andik spring water (3.8 mg/L flour level) as drinking water. In this study we aimed to investigate the harmful effect of floride on human erythrocytes via antioxidant defence system and lipid peroxidation. Therefore, we studied the activities of erythrocyte antioxidant enzymes such as Superoxide Dismutase (SOD), Glutathione Peroxidase (GSH-Px) and Catalase (CAT), and the level of erythrocyte Glutathione (GSH), thiobarbituric acid reactive substance (TBARS) and the level of urine floride in high floride exposed people (children, adult and elderly). The activities of SOD, GSH-Px and CAT and the level of GSH, TBARS and urine floride were higher in 3.8 mg/L floride exposed children (Group II) than 0.8 mg/L floride exposed control children (Group I) (p 0.05). The activities of SOD, GSH-Px and CAT were lower and the levels of TBARS and urine floride were higher in 3.8 mg/L floride exposed elderly people (Group VI) than 0.8 mg/L floride exposed control elderly people (Group V) (p 0.05). As a result we thought that increased SOD, GSH-Px and CAT activities in floride exposed children and adult people, decreased activities of these enzymes in floride exposed elderly people, and increased TBARS in all groups may indicate floride caused oxidative damage in erythrocytes.

    Full Text Available Introduction: The regular practice of physical activity is fundamental to the health of children, it has been cited as factor of protection for mental disorders in school age. Objective: To verify the relation between mental health and physical activity levels in schoolchildren of the city Jacobina, Bahia. Method: Sample composed of 55 students between the ages 08 to 10 and their parents, who participated as secondary informants in this study. The Child Behavior Checklist (CBCL was used for evaluation of mental health problems of the schoolchildren, Physical Activity Questionnaire for Older Children (PAQ-C, for evaluation of the physical activity levels of the subject, and a social-demographic questionnaire. Results: Most children were classified as sedentary (80% and only 7.3% of the sample showed positive for trace of mental disorder. No significant association was found between mental disorders and physical activity levels among the group, or between these variables and socio-demographic characteristics of children. It was observed that the girls were more sedentary than boys, with significant difference (p < 0.01. Conclusion: Despite the low prevalence of mental health problems among schoolchildren and the non-association with physical activity levels, special attention is necessary with this audience, aiming to strengthen physical activity as a protective factor for children’s mental health, with investments in actions aimed at the encouragement of regular practice of physical activity, combining family and school. Studies with a larger number of samples need to be conducted and its findings must be thoroughly analyzed.

  8. Click-Evoked Auditory Efferent Activity: Rate and Level Effects.

    There currently are no standardized protocols to evaluate auditory efferent function in humans. Typical tests use broadband noise to activate the efferents, but only test the contralateral efferent pathway, risk activating the middle ear muscle reflex (MEMR), and are laborious for clinical use. In an attempt to develop a clinical test of bilateral auditory efferent function, we have designed a method that uses clicks to evoke efferent activity, obtain click-evoked otoacoustic emissions (CEOAEs), and monitor MEMR. This allows for near-simultaneous estimation of cochlear and efferent function. In the present study, we manipulated click level (60, 70, and 80 dB peak-equivalent sound pressure level [peSPL]) and rate (40, 50, and 62.5 Hz) to identify an optimal rate-level combination that evokes measurable efferent modulation of CEOAEs. Our findings (n = 58) demonstrate that almost all click levels and rates used caused significant inhibition of CEOAEs, with a significant interaction between level and rate effects. Predictably, bilateral activation produced greater inhibition compared to stimulating the efferents only in the ipsilateral or contralateral ear. In examining the click rate-level effects during bilateral activation in greater detail, we observed a 1-dB inhibition of CEOAE level for each 10-dB increase in click level, with rate held constant at 62.5 Hz. Similarly, a 10-Hz increase in rate produced a 0.74-dB reduction in CEOAE level, with click level held constant at 80 dB peSPL. The effect size (Cohen's d) was small for either monaural condition and medium for bilateral, faster-rate, and higher-level conditions. We were also able to reliably extract CEOAEs from efferent eliciting clicks. We conclude that clicks can indeed be profitably employed to simultaneously evaluate cochlear health using CEOAEs as well as their efferent modulation. Furthermore, using bilateral clicks allows the evaluation of both the crossed and uncrossed elements of the auditory

    To examine how motives discriminate 3 physical activity levels of inactive, active, and sustained maintainers. Six hundred forty-five adults (M age = 63.8) completed stage-of-change and Exercise Motivations Inventory (EMI-2) scales. Exploratory factor analysis established psychometric properties of the EMI-2 suitable for older adults. Six factors emerged in the EMI-2: health and fitness, social/emotional benefits, weight management, stress management, enjoyment, and appearance. Enjoyment contributed most to differentiating activity levels. Moderators of age and gender were delineated. Intrinsic motivation and self-determined extrinsic motivation distinguish older adults' activity levels.

  10. Default activity patterns at the neocortical microcircuit level

    2012-06-01

    Full Text Available Even in absence of sensory stimuli cortical networks exhibit complex, self-organized activity patterns. While the function of those spontaneous patterns of activation remains poorly understood, recent studies both in vivo and in vitro have demonstrated that neocortical neurons activate in a surprisingly similar sequential order both spontaneously and following input into cortex. For example, neurons that tend to fire earlier within spontaneous bursts of activity also fire earlier than other neurons in response to sensory stimuli. These 'default patterns' can last hundreds of milliseconds and are strongly conserved under a variety of conditions. In this paper we will review recent evidence for these default patterns at the local cortical level. We speculate that cortical architecture imposes common constraints on spontaneous and evoked activity flow, which result in the similarity of the patterns.

  19. Changing memory of food enjoyment to increase food liking, choice and intake.

    Robinson, Eric; Blissett, Jackie; Higgs, Suzanne

    2012-10-28

    Novel ways to increase liking and intake of food are needed to encourage acceptance of healthier food. How enjoyable we remember food to have been is likely to be a significant predictor of food choice. Two studies examined whether remembered enjoyment of eating a food can be increased and whether this makes individuals more likely to eat that food in the future. In Study One, a simple manipulation of instructing participants to rehearse what they found enjoyable about a food immediately after eating it was used to increase remembered enjoyment (relative to controls). In a separate study; Study Two, the effect of increasing remembered enjoyment on food choice was tested by examining whether the manipulation to increase remembered enjoyment resulted in participants choosing to eat more of a food as part of a later buffet lunch. The experimental manipulation increased remembered enjoyment for the food (Study One). A change in remembered enjoyment was shown to have a significant effect on the amount of a food participants chose to eat the following day for lunch (Study Two). The present studies suggest that remembered enjoyment can be increased via a simple act of rehearsal, resulting in a later increase in the amount of food chosen and eaten. Interventions based on altering remembered enjoyment of healthy food choices warrant further investigation.

    Whole-body irradiation of rats results in the release of hydrolases from lysosomes, an increase in lysosomal enzyme activities, and changes in the prostaglandin levels in spleen and liver tissues. A transient increase in the concentration of prostaglandins E and F and leakage of lysosomal hydrolases occurred in both spleen and liver tissues 3-6 hours after the animals were irradiated. Maximal values for hydrolase activities, prostaglandin E and F content, and release of lysosomal enzymes were found 4 days postirradiation in rat spleens whereas in the liver only slight increases were observed at this time period for prostaglandin F levels. On day 7 there was a final rise in the spleen's prostaglandin E and F concentrations and leakage of hydrolases from the lysosomes before returning to near normal values on day 11. The prostaglandin F concentration in liver was also slightly elevated on the 7th day after irradiation and then decreased to control levels. (author)

  3. Anthropogenic noise alters bat activity levels and echolocation calls

    2015-01-01

    Full Text Available Negative impacts from anthropogenic noise are well documented for many wildlife taxa. Investigations of the effects of noise on bats however, have not been conducted outside of the laboratory. Bats that hunt arthropods rely on auditory information to forage. Part of this acoustic information can fall within the spectrum of anthropogenic noise, which can potentially interfere with signal reception and processing. Compressor stations associated with natural gas extraction produce broadband noise 24 hours a day, 365 days a year. With over half a million producing gas wells in the U.S. this infrastructure is a major source of noise pollution across the landscape. We conducted a ‘natural experiment’ in the second largest gas extraction field in the U.S. to investigate the potential effects of gas compressor station noise on the activity levels of the local bat assemblage. We used acoustic monitoring to compare the activity level (number of minutes in a night with a bat call of the bat assemblage at sites with compressor stations to sites lacking this infrastructure. We found that activity levels for the Brazilian free-tailed bat (Tadarida brasiliensis were 40% lower at loud compressor sites compared to quieter well pads, whereas the activity levels of four other species (Myotis californicus, M. cillolabrum, M. lucifugus, Parastrellus hesperus were not affected by noise. Furthermore, our results reveal that the assemblage of bat species emitting low frequency (35 kHz echolocation did not exhibit altered activity levels in noise. Lower activity levels of Brazilian free-tailed bats at loud sites indicate a potential reduction in habitat for this species. Additionally, a comparison of echolocation search calls produced by free-tailed bats at sites with and without compressor stations reveal that this species modifies its echolocation search calls in noise—producing longer calls with a narrower bandwidth. Call alterations might affect prey

    The aim of this study was to objectively quantify ratings of perceived enjoyment using the Physical Activity Enjoyment Scale following high-intensity interval running versus moderate-intensity continuous running. Eight recreationally active men performed two running protocols consisting of high-intensity interval running (6 × 3 min at 90% VO(2max) interspersed with 6 × 3 min active recovery at 50% VO(2max) with a 7-min warm-up and cool down at 70% VO(2max)) or 50 min moderate-intensity continuous running at 70% VO(2max). Ratings of perceived enjoyment after exercise were higher (P running compared with continuous running (88 ± 6 vs. 61 ± 12) despite higher (P running may be relevant for improving exercise adherence, since running is a low-cost exercise intervention requiring no exercise equipment and similar relative exercise intensities have previously induced health benefits in patient populations.

    2018-01-01

    Full Text Available The article explores the concept of corruption, defined as an obstacle to economic and social development, created by representatives of the power structures of the country, region, enterprise, weakening the efficiency of management and the institutional foundation of society. Anticorruption activity is presented in the article as conditions created by the state and ensuring that the country's economy is not irreparably damaged by internal and external economic threats. The estimated characteristics of the anti-corruption activities of the regions and the country as a whole, as a rule, are studied in the domestic sources and among foreign authors. Statistical evaluation of the relationship between the level of corruption and indicators: the dynamics of GRP growth, the index of real incomes of the population, the costs of training, health care is made on the basis of the coefficient Pearson correlation. Based on the correlation analysis, stable links were established between the level of corruption and the socio-economic indicators of the region's development: an increase in the level of corruption associated with an increase in the population's spending on education and medicine; a reduction in the level of corruption, as a result of increased incomes of the population and higher wages. The consequences of corruption are presented: legal (the undeveloped legislative base, which involves bribery of powerful people, the growth of corruption in the society, the increase in corruption crimes, the inefficiency of the regulatory framework, social (moral violation, low public evaluation of the activities of power structures, low level of culture and upbringing , economic (bias financial, investment decisions, illegal distribution of property and non-property benefits, the impossibility of competitors Vat with developed countries and others.

The objective of this study was to examine the association between classifications obtained with the cardiorespiratory fitness test and physical activity level in adolescents, as well as the agreement between tertiles and z-score distribution of the variables generated with these methods (distance covered and total physical activity score. A cross-sectional study was conducted using a random sample of 639 adolescents (61% girls aged 12 to 19 years (mean age of 16 ± 1.8 and categorized into two age groups: 12-13 and 14-19 years, from public schools in Niterói, Rio de Janeiro, Brazil. Cardiorespiratory fitness was assessed by a 9-min run/walk test (T9 and physical activity level by the International Physical Activity Questionnaire (IPAQ. The chi-square test (or Fisher’s exact test and Kruskal-Wallis test were applied for the evaluation of associations, and the weighted kappa coefficient and intraclass correlation coefficient were used to investigate agreement between variables. A level of significance of p<0.05 was adopted. A significant association between the classifications obtained with the two methods was only observed for adolescents aged ≥ 14 years. However, there was agreement between the variables generated with the two methods in both age groups. The median distance covered in the T9 increased according to tertiles of total physical activity score. An association between the classifications obtained with the IPAQ and T9 was only found for older adolescents. However, the continuous variables and variables categorized into tertiles generated with the methods were associated and showed agreement in both age groups.

    Full Text Available Background: postnatal depression (PND is defined as a psychological mood disorder that occurs in a mother within six weeks of her giving birth. It refers to an episode that causes mood disturbance and it could begin in, or extend into, the postpartum period. It is thought to have a high impact upon the mother’s health as well as the family’s functioning and the child’s development. Socio-demographic, psych-social, and physical activity factors may all contribute to postpartum mood and ability to cope with responsibilities. The primary aim of this study was to determine which of these factors predicted PND in postpartum women. A secondary aim was to identify the socio-demographic and psycho-social predictors of physical activity in postpartum women . Methods: The study used a cross-sectional correlational design. A sample of 150 postpartum women was sent a package of six standardised questionnaires. Results: There was no association between physical activity and PND; however, older mothers, mothers of younger children, mothers who are less reluctant to ask for help, and mothers who are more satisfied with the help they get experience lower levels of PND. Mothers of older babies, mothers with more children, and less educated mothers are more likely to engage in caregiving activities, whereas mothers with fewer children and higher levels of partner support are more likely to engage in occupational activities. None of the socio-demographic factors or any of the parenting factors predicted levels of sporting activity.

    Associations among personality as measured by the Five Factor Model, physical activity, and muscle strength were assessed using data from the Baltimore Longitudinal Study of Aging (N = 1220, age: mean = 58, SD = 16). General linear modeling with adjustment for age, sex, race, and body mass index, and bootstrapping for mediation were used. We found neuroticism and most of its facets to negatively correlate with strength. The extraversion domain and its facets of warmth, activity, and positive-emotions were positively correlated with strength, independent of covariates. Mediation analysis results suggest that these associations are partly explained by physical activity level. Findings extend the evidence of an association between personality and physical function to its strength component and indicate health behavior as an important pathway. PMID:23966753

    To compare physical activity level (PAL) and care related to exercise in patients with diabetes mellitus (DM). DM outpatients (adult, insulin-user patients) were assessed for PAL (international questionnaire; moderate- and high-level activities, as well as walking, over a typical week) and questioned about formal exercise practice, self-care, and hypoglycemic episodes related to exercise or reasons for not exercising. Two hundred twenty five patients were assessed: 107 (47.6%) had type 2 diabetes mellitus (DM2) and 118 (52.4%) had type 1 diabetes mellitus (DM1), with a larger percentage of patients with DM2 being classified as poorly active [33 (30.7%) versus 12 (10.3%)] and a lower percentage being classified as highly active [9 (8.7%) versus 29 (25%)], compared with patients having DM1. Patients who do not exercise (n = 140) gave different reasons for not doing so: patients with DM2 claimed that they "felt uncomfortable", "presented medical restrictions", and "did not like it"; DM1 patients claimed that they "had no time to exercise", "were lazy", and "had hypoglycemic episodes". Only 85 patients exercised regularly, regardless of the PAL, and 38.8% performed self-care, such as eating, stretching, and capillary glucose monitoring. Patients with DM2 [5 (14.3%)] reported a lower number of hypoglycemic episodes related to exercise than those with DM1 [17 (34%)]. Patients with DM2 have different PAL and behavior related to exercise than those seen in DM1 patients.

    Given the benefits of physical activity and the high proportion of inactivity among older adults, the purpose was to elicit theory-based behavioral, normative, and control physical activity beliefs among 140 educationally and economically diverse older adults and compare their beliefs by race (Blacks vs. Whites) and physical activity levels (inactive/underactive vs. highly active individuals). This was an elicitation study that took place in eight, mostly rural community settings in a Southeastern US state, such as Council of Aging Offices, retirement centers, and churches. Participants' behavioral, normative, and control beliefs were elicited via in person interviews. A valid and reliable questionnaire was also used to assess their physical activity levels. According to the content analysis, inactive/underactive participants reported fewer physical activity advantages than highly active participants. Common physical activity advantages between the two groups were overall health, emotional functioning, and physical functioning. Similar physical activity advantages were reported among Blacks and Whites with overall health being the most important advantage. The most common physical activity disadvantages and barriers for all four groups were falls, injuries, pain, and health issues. Inactive/underactive individuals and Blacks tended to report more disadvantages and barriers than their peers. Common physical activity supporters were family members, friends and peers, and health-care professionals. In their physical activity motivational programs, health promoters should reinforce physical activity benefits, social support, access to activity programs, and safety when intervening among older adults.

The participants with chronic pain (12 were identified from the Groote Schuur Hospital, Chronic Pain Management Clinic (CPMC waiting list and had not yet received any chronic pain management intervention. Healthy matched controls were selected from volunteers in the community. With the desired alpha level set at 0.05 and the power at 0.9, 45 participants were required to detect a minimum of a 50 per cent difference between groups in levels of physical activity as measured in steps per day using pedometers. The international physical activity questionnaire (IPAQ and the brief pain inventory (BPI were used as measures of physical activity and pain. Objective indicators of physical activity that were used included the 6-minute walk test (6MWT, repeated sit-to-stand test (RSST, 7 days of pedometry and body mass index (BMI. Results: The chronic pain group performed significantly worse on the 6MWT (335 m [30–430] vs 680 m [430–795]; U = 0.5; p < 0.01 and on the RSST (17.9 s [11.83–105] vs 7.85 s [5.5–11.5]; U = 0; p < 0.01. The chronic pain group also had significantly lower scores on pedometry (mean daily: 2985.1 [32.8–13785.4] vs 6409.4 [4207.1–15313.6]; U = 35; p < 0.03. The BMI for the chronic pain group was significantly higher than matched controls (29.36 kg/m2 [18.94–34.63] vs 22.16 kg/m2 [17.1–30.86]; U = 34; p < 0.03. Conclusion: Participants with chronic pain

    The main goals of this study were: (1) to examine the relationship between physical activity (PA) involvement and other leisure activities in a sample of Portuguese youth and (2) to analyze gender differences in PA and leisure-time activity structure. The sample comprised 1123 adolescents that were classified according to PA levels as active (n = 589) and nonactive (n = 534). A questionnaire assessing leisure-time activities was used. Girls were significantly more engaged in social leisure, dutiful, and individual artistic activities during leisure time, whereas boys were more involved in sports and computer and TV viewing activities. Significant associations between PA and social leisure were found in girls (r = .18, P leisure (girls: r = .56, P importance of organized and nonorganized sports/PA during leisure time for overall levels of PA in adolescents.

    The objective of this study was to identify the interconnectedness of different intensity levels of physical activity and psychological (life satisfaction and positive affect) and physical (physical health) well-being. Participants were from the National Study of Midlife in the United States with assessments in 2004 and aged 25 to 74 living in the United States were included in the analyses. We conducted bivariate correlations to examine significant relationships among the study variables. In addition, after multicollinearity among the independent variable was checked, a series of hierarchical regression analyses with physical health, positive affect, and life satisfaction as criterion variables were conducted. The results showed that light physical activities were positively associated with physical health and life satisfaction in summer, whereas light physical activities and all dependent variables were positively correlated in winter. Furthermore, engaging in moderate physical activities was positively related only with physical health. Meanwhile, vigorous physical activities were not associated with life satisfaction, physical health, and positive affect in summer and winter.

    To develop a tool to measure the influencing nurses' enjoyment of nursing. Enjoyment in the workplace is an influential aspect found to boost work morale, job satisfaction leading to higher work retention which is important in nursing given the availability of nurses in the workforce. This study looks to refine the determinants of enjoyment from nurses in a large metropolitan hospital in western Sydney. Quantitative. A 23-item survey questionnaire was used to ask nurses to rate the determinants that affect their enjoyment of nursing on a five-point Likert scale. The survey was distributed in a hard copy and online through a hospital-wide broadcast. Demographic items were also collected. A total of 124 responses were received, of which 54 were from online and 70 from hard copy surveys. The data analysis found 16 determinants of enjoyment. Of these, four were perceived by over 80% of the nurses to negatively impact their enjoyment. In contrast, nine items showed a positive effect on enjoyment with educating others, connecting with others, variety of work, doing and sharing with others, supporting others being the most positive (≥89% of responses). Three items were considered neutral: criticism, busy workload and changing policies. This study has added to the growing evidence on nurse enjoyment and its effects on job satisfaction. Nurses enjoy caring for patients and also find enjoyment and satisfaction in teaching others to care as well as socially connecting. Enjoyment seems to be one of the main reasons nurses continue to stay in nursing even though the system and people are not always supportive, encouraging or conducive to career development. © 2016 John Wiley & Sons Ltd.

  19. State and Federal activities on low-level waste

    1983-01-01

    With the passage of the Low-Level Waste Policy Act in December 1980, the states have assumed the management responsibility and the federal government has become a facilitator. State and Federal roles in regulation have not altered. This paper reviews the developments over the last two years to point out the progress made and critical steps that lie ahead. Both technological and political aspects are covered, and a conclusion is presented with a look to the future. Since compact development in the tool chosen by the politicans for low-level waste management, the author reviews the present status starting with the northwest compact which has been introduced into the House and Senate and is subject to hearings. The past two years have seen real progress in technology in the broadest sense. An information development and dissemination system was established in 1978 wih the state-by-state assessment of low-level waste disposal. Annual examinations have been made through 1981 which enables one to understand the generation of low-level wastes. Policy level planning by states can be supported by the base level of information available. Incineration of dry active waste and other non-fuel cycle waste is ready to be fully accepted. Much work has been done on volume reduction of liquids. The increased understanding of the ways to make a disposal site work represents a major technolological improvement. Within the DOE system, there is beginning to be a real understanding of the critical parameters in disposal site performance in the East

    This study examined whether satisfaction from leisure activities moderates the relationship between caregiving demands (i.e., hours per day spent caring for a spouse with dementia) and resting levels of the catecholamines norepinephrine (NE) and epinephrine (EPI). Spousal caregivers (n = 107; mean age = 73.95 ± 8.12 years) were assessed in home for plasma levels of NE and EPI, amount of care provided, and leisure satisfaction. Regression was used to determine whether leisure satisfaction moderated the relationship between hours providing care per day and catecholamine levels. A significant interaction was found between hours caregiving and leisure satisfaction for NE, but not for EPI. Post hoc regressions were conducted for both NE and EPI. At low leisure satisfaction, time spent caring for a spouse was positively associated with plasma NE (β = 0.41; p = 0.005) and EPI (β = 0.44; p = 0.003). In contrast, at high levels of satisfaction, time caregiving was not significantly associated with plasma NE (β = -0.08; p = 0.57) or EPI (β = 0.23; p = 0.12). These findings suggest that leisure satisfaction may protect caregivers from increases in catecholamines, which have been implicated in cardiovascular risk. Further support for these findings may impact psychological treatments for distressed caregivers.

    Pulse shape discrimination of α and β rays with liquid scintillation counting was investigated for the purpose of low level α activity measurements. Various liquid scintillators for pulse shape discrimination were examined by means of pulse rise time analysis. A new scintillator of low cost and of superior characteristics was found. The figure of merits better than 3.5 in risetime spectrum and the energy resolution better than 9% were obtained for carefully prepared samples. The background counting rate for a sample of 10 ml was reduced to 0.013 cpm/MeV in the range of α ray energy 5 to 7 MeV. (author)

    A program has been carried out to characterize the Dry Active Waste (DAW) stream from a typical PWR power plant in order to determine the usefulness of large-volume DAW monitors for segregating such waste in order to dispose of it in appropriate facilities. A waste monitor using plastic scintillation counters was used for measuring the waste. The monitor had a volume of about 300 liters and an overall efficiency of about 12% for a typical fission product mixture. It provides automatic compensation for background radioactivity and can measure a bag of waste in less than a minute, including background measurements. Six hundred consecutively generated bags of DAW were measured. These had a total activity of about one millicurie and an average specific activity of about 540 nanocuries per kilogram. About half of the bags contained less than 1000 nanocuries and had specific activities of less than 100 nanocuries per kilogram. Based on simplified preliminary calculations, it appears that an evaluation of the risks of disposal of bags such as these in a landfill other than a low-level waste disposal facility could be carried out that would demonstrate that such disposal of half or more of these bags would not result in any substantial hazard, either short or long term

    Eight studies assessed the motive for sensory pleasure (MSP) involving a general disposition to enjoy and pursue pleasant nature-related experiences and avoid unpleasant nature-related experiences. The stated enjoyment of pleasant sights, smells, sounds, and tactile sensations formed a unitary construct that was distinct from sensation seeking, novelty preference, and need for cognition. MSP was found to be related to (a) enjoyment of pleasant nature scenes and music of high but not low clarity; (b) enjoyment of writings that portrayed highly detailed nature scenes; (c) enjoyment of pleasantly themed paintings and dislike of unpleasant paintings, as distinct from findings with Openness to Experience; (d) choice of pleasant nature scenes over exciting or intellectually stimulating scenes; (e) view duration and memory of artistically rendered quilts; (f) interest in detailed information about nature scenes; and (g) frequency of sensory-type suggestions for improvement of a museum exhibit.

    The main aim of the research was to examine the relationship between motivational orientations and parents’ behavior with regard to the players’ motivational orientation, motivational climate, enjoyment and amotivation. The sample comprised 723 athletes (M = 12.37, SD = 1.48) and 723 parents (M = 46.46, SD = 2.56). Players were male and female who belonged to federative basketball, handball, football and volleyball teams. Parents and athletes completed questionnaires that assessed motivational orientations, parents’ involvement in the practice as well as enjoyment and motivation in the sport. Results showed a positive relationship between parents’ support of the sport and players’ enjoyment and a negative relationship with players’ amotivation. Moreover, in players who perceived more pressure from their parents, there was a positive association with amotivation and a negative one with enjoyment. Lastly, it was emphasized that appropriate parental participation can promote an increase of players’ enjoyment of and motivation for sport. PMID:23717366

    Full Text Available Previous studies investigating the effects of high intensity interval training (HIIT and moderate intensity continuous training (MICT showed controversial results. The aim of the present study was to systematically review the literature on the effects of HIIT and MICT on affective and enjoyment responses. The PRISMA Statement and the Cochrane recommendation were used to perform this systematic review and the database search was performed using PubMed, Scopus, ISI Web of Knowledge, PsycINFO, and SPORTDiscus. Eight studies investigating the acute affective and enjoyment responses on HIIT and MICT were included in the present systematic review. The standardized mean difference (SMD was calculated for Feeling Scale (FS, Physical Activity Enjoyment Scale (PACES and Exercise Enjoyment Scale (EES. The MICT was used as the reference condition. The overall results showed similar beneficial effects of HIIT on PACES and EES responses compared to MICT with SMDs classified as small (PACES-SMD = 0.49, I2 = 69.3%, p = 0.001; EES-SMD = 0.48, I2 = 24.1%, p = 0.245 while for FS, the overall result showed a trivial effect (FS-SMD = 0.19, I2 = 78.9%, p<0.001. Most of the comparisons performed presented positive effects for HIIT. For the FS, six of 12 comparisons showed beneficial effects for HIIT involving normal weight and overweight-to-obese populations. For PACES, six of 10 comparisons showed beneficial effects for HIIT involving normal weight and overweight-to-obese populations. For EES, six of seven comparisons showed beneficial effects for HIIT also involving normal weight and overweight-to-obese populations. Based on the results of the present study, it is possible to conclude that HIIT exercise may be a viable strategy for obtaining positive psychological responses. Although HIIT exercise may be recommended for obtaining positive psychological responses, chronic studies should clarify the applicability of HIIT for exercise adherence.

    Several classic studies have concluded that the accuracy of identifying uncontrollable situations depends heavily on depressive mood. Nondepressed participants tend to exhibit an optimistic illusion of control, whereas depressed participants tend to better detect a lack of control. Recently, we suggested that the different activity levels (measured as the probability of responding during a contingency learning task) exhibited by depressed and nondepressed individuals is partly responsible for this effect. The two studies presented in this paper provide further support for this mediational hypothesis, in which mood is the distal cause of the illusion of control operating through activity level, the proximal cause. In Study 1, the probability of responding, P(R), was found to be a mediator variable between the depressive symptoms and the judgments of control. In Study 2, we intervened directly on the mediator variable: The P(R) for both depressed and nondepressed participants was manipulated through instructions. Our results confirm that P(R) manipulation produced differences in the participants' perceptions of uncontrollability. Importantly, the intervention on the mediator variable cancelled the effect of the distal cause; the participants' judgments of control were no longer mood dependent when the P(R) was manipulated. This result supports the hypothesis that the so-called depressive realism effect is actually mediated by the probability of responding.

    Full Text Available Physical Activity (PA is very important during childhood and adolescence in order to promote healthy development and prevent obesity. The WHO recommends 60 minutes daily of moderate-vigorous activity (e» 3 METs/day. The main objective of the study is to assess the levels of PA intensity performed daily by adolescents from a school using the triaxial accelerometry system and to know if they achieve the WHO recommendations. The sample size was 60 Spanish adolescents (14.52 ± .854 year-old belongs to the Empordá school (Empúries, Spain. Previous informed consent was obtained from their parents and/or tutors. PA levels were obtained through accelerometry, Body Mass Index (BMI was calculated though weight and height, heart rate (HR and blood pressure (BP were measured using a digital automatic blood pressure monitor. Descriptive for all data was calculated, and T–test (p < .05 was used to analyze the differences between boys and girls. The main result show that males performed PA during longer time and at higher intensity than women. There is a low percentage of students who achieve the WHO recommendations. In conclusion, we believe very important to seek new strategies and methods to involve more adolescents in the practice of PA, and we believe that PA sessions at school are very important.

    To objectively assess physical activity (PA) levels in a cohort of Spanish cancer survivors. Descriptive, cross-sectional. The Hospital Universitario de Fuenlabrada and two healthcare centers in Madrid, Spain. 204 cancer survivors and 115 adults with no history of cancer. Participants wore a triaxial accelerometer for seven or more consecutive days to assess PA levels. Body mass index (BMI), indirect indicators of adiposity (waist circumference, waist-to-hip ratio), and cardiorespiratory fitness also were determined. Light, moderate, vigorous, and total PA (sum of the former). Most (94%) of the cancer survivors met international recommendations for moderate PA, but very few (3%) fulfilled those (75 minutes or more per week) for vigorous PA. Except for lower total (minute per day, p=0.048) and vigorous PA levels (p0.05). A high percentage of the survivors (33%) were obese (BMI greater than 30 kg/m2), and many also showed poor cardiorespiratory fitness (45% were below the 8 metabolic equivalent threshold). Although cancer survivors overall met international PA recommendations for a healthy lifestyle, their BMI and cardiorespiratory profiles were not within the healthy range. Cancer survivors need to be informed about healthy lifestyle habits and should be regularly monitored.

    Research into pathogenesis of multiple sclerosis (MS) has prompted efforts to identify immunological markers associated with disease activity. Adhesion molecules ICAM-1 and VCAM-1 are associated with inflammatory mediated blood-brain barrier (BBB) dysfunction. In this study investigates the correlation between blood level of circulating ICAM-1 and VCAM-1 and magnetic resonance imaging (MRI) activity in different clinical phases of patients with MS. We show that RRMS and SPMS patients in clinically active phase with Gd-enhancing lesions in CNS had higher blood levels of cICAM-1 and cVCAM-1 compared these parameters levers of RRMS patients in remission stage. These results suggest that cICAM-1 and cVCAM-1 is a sensitive indicator of disease activity associated with BBB inflammatory dysfunction. Elevated blood level of cICAM-1 more strongly correlated with clinical activity and BBB damage, than cVCAM-1 and that could be used as biological marker of disease activity. Circulating VCAM-1 as an early indicator of BBB disturbance, may also serve as marker of beneficial activity in relapses phase of MS course. (authors)

    Fundamental movement skills (FMS) have been assessed in children in order to investigate the issues of the low proportion of children who meet physical activity (PA) guidelines and rising levels of obesity. The aim of this research was to identify whether previous or current FMS level is a better predictor of PA levels and weight status in children. In January 2012 (year 1), 281 children were recruited from one primary school in the West Midlands, UK. Children performed eight FMS three times, which were videoed and assessed using a subjective checklist. Sprint speed and jump height were measured objectively. Height and mass were measured to calculate the body mass index to determine the weight status. Skinfold calliper readings were used to calculate body fat percentage. One year later, in January 2013, all these tests were repeated on the same children, with the additional collection of PA data via the use of pedometers. Following multiple linear regression, it was identified that prior mastery in FMS was a better predictor of current PA, whereas current FMS was a better predictor of current weight status. Overall, FMS mastery is needed in childhood to be able to participate in PA and maintain a healthy weight status.

    Objective The aim of this study was to compare the effects of 5-week high-intensity interval training (HIIT) and moderate-to-vigorous intensity continuous training (MVCT) on cardiometabolic health outcomes and enjoyment of exercise in obese young women. Methods A randomized controlled experiment was conducted that involved thirty-one obese females (age range of 18–30) randomly assigned to either HIIT or MVCT five-week training programs. Participants in HIIT condition performed 20 min of repeated 8 s cycling interspersed with 12 s rest intervals, and those in MVCT condition cycled continuously for 40 min at 60–80% of peak oxygen consumption (V˙O2peak), both for four days in a week. Outcomes such as V˙O2peak, body composition estimated by bioimpedance analysis, blood lipids, and serum sexual hormones were measured at pre-and post-training. The scores of Physical Activity Enjoyment Scale (PAES) were collected during the intervention. Results After training, V˙O2peak increased significantly for both training programs (9.1% in HIIT and 10.3% in MVCT) (p = 0.010, η2 = 0.41). Although MVCT group had a significant reduction in total body weight (TBW, −1.8%, p = 0.034), fat mass (FM, - 4.7%, p = 0.002) and percentage body fat (PBF, −2.9%, p = 0.016), there were no significant between-group differences in the change of the pre- and post-measures of these variables. The HIIT group had a higher score on PAES than the MVCT group during the intervention. For both conditions, exercise training led to a decline in resting testosterone and estradiol levels, but had no significant effect on blood lipids. Conclusion Both HIIT and MVCT are effective in improving cardiorespiratory fitness and in reducing sexual hormones in obese young women; however, HIIT is a more enjoyable and time-efficient strategy. The mild-HIIT protocol seems to be useful for at least maintaining the body weight among sedentary individuals. PMID:27368057

    2000-11-16

    This plan has been prepared in response to direction from the U.S. Department of Energy. The purpose of the plan is to define approaches that will be implemented to ensure protection of the public and the environment when active Low-Level Burial Grounds (LLBGs) at the Hanford Site are closed. Performance assessments for active burial grounds in the 200 East and West 200 Areas provide current estimates of potential environmental contamination and doses to the ''maximum exposed individual'' from burial ground operation and closure and compare dose estimates to performance objective dose limits for the facilities. This is an Operational Closure Plan. The intent of the guidance in DOE Order 435.1 is that this plan will be a living document, like the facility performance assessments, and will be revised periodically through the operational life of the LLBGs to reflect updated information on waste inventory. management practices, facility transition planning, schedule dates, assessments of post-closure performance, and environmental consequences. Out year dates identified in this plan are tentative. A Final Closure Plan will be prepared in the future when the timing and extent of closure-related activities for LLBGs can be established with greater certainty. After current operations at the LLBGs are concluded, this plan proposes transitioning of these facilities to the Environmental Restoration Program. This action will enable the Environmental Restoration Program to design and implement consistent and coordinated final remedial actions for active and inactive LLBGs. Active and inactive burial grounds in the 200 West and 200 East Areas are commingled. This plan describes approaches that will be implemented during Interim Closure, Final Closure, and Institutional Control Periods to prepare LLBGs for surface barriers, and the construction of barriers, as well as the scope of inspection, monitoring and maintenance practices that will be performed during

    Full Text Available Objective: Military service is a highly stressful period both for the soldiers serving and for their parents. Surprisingly, parents’ experience has been mostly ignored in the research. This study’s goal is to shed light on the experience and distress levels of parents of active duty combat soldiers during Operation Protective Edge, a military operation carried out by the Israel Defense Forces during July and August of 2014.Methods: During the advanced stages of the operation, 69 parents of Israeli male combat soldiers (55 mothers and 14 fathers completed an online survey measuring symptoms of Posttraumatic Stress Disorder (PTSD-Checklist-5 and distress (Brief Symptom Inventory-18. Participants were recruited using a convenience sample, by posting ads on the public Facebook pages of the researchers and of the groups dedicated to parents of Israeli soldiers.Results: Parents’ depression and anxiety symptom levels were higher than depression and anxiety symptom levels of the adult community norms in Israel. General distress rates of parents were similar to those presented by adults in southern Israel who were exposed for 7 years to the ongoing threat of daily rocket fire from Gaza, and higher than rates of a non-threatened Israeli population. Finally, 20.2% of the parents presented PTSD-like symptoms, a higher percentage than the probable PTSD diagnosis rates that were found in the general population in Israel during previous terror waves.Conclusion: This study provides preliminary evidence of soldiers’ parents’ distress and indicates the need for a better understanding of the impact of military service on soldiers’ parents.

The patients also completed the International Physical Activity Questionnaire (IPAQ, short version, and the modified Baecke questionnaire (mBQ. The level of physical activity was assessed by the number of steps/day (as determined by pedometer, using the cut-off of 4,580 steps/day to form two groups: no severe physical inactivity (SPI− and severe physical inactivity (SPI+. We used the Mann-Whitney test or t-test, as well as Pearson's or Spearman's correlation tests, in the statistical analysis.RESULTS: In comparison with the SPI− group, the SPI+ group showed more advanced age, higher mBQ scores (leisure domain, lower 6MWD (in m and % of predicted, and lower IPAQ scores (metabolic equivalent-walk/week domain and total. The IPAQ scores showed weak correlations with steps/day (r = 0.399, age (r = −0.459, and 6MWD-in m (r = 0.446 and in % of predicted (r = 0.422.CONCLUSIONS: In our sample, the cut-off of 4,580 steps/day was not sensitive enough to identify differences between the groups when compared with the predictors of mortality. The IPAQ, short version score correlated with steps/day.

    2013-10-01

    Full Text Available Many adolescents are not meeting recommended levels for physical activity. Increasing physical activity among urban African American youth is both a challenge and a public health priority. Most research in community-based interventions has taken a didactic approach, focusing on skill and knowledge development alone, with inconclusive results. This ten-week progressive activity intervention with adolescents in an urban faith community introduced a self-determination theory (SDT approach with the aim of promoting the adoption of self-management skills necessary for sustaining activity. Components of SDT included relatedness, competence, and autonomy. Together with didactics, aligning activities with participant interests, and using existing social structures for health message delivery, the approach led to high satisfaction ratings for the three components of SDT along with improved skills, knowledge, and outcomes in cardiovascular fitness. Understanding and utilizing approaches that enhance enjoyment, personal choice, confidence, and social affiliation may lead to more lasting healthy activity behaviors and attitudes than didactic approaches alone in this and other adolescent populations. The SDT is reviewed in the context of this youth intervention.

    Full Text Available Abstract Background Although physical activity recommendations for public health have focused on locomotive activity such as walking and running, it is uncertain how much these activities contribute to overall physical activity level (PAL. The purpose of the present study was to determine the contribution of locomotive activity to PAL using total step counts measured in a calorimeter study. Methods PAL, calculated as total energy expenditure divided by basal metabolic rate, was evaluated in 11 adult men using three different conditions for 24-hour human calorimeter measurements: a low-activity day (L-day targeted at a low active level of PAL (1.45, and a high-frequency moderate activity day (M-day or a high-frequency vigorous activity day (V-day targeted at an active level of PAL (1.75. These subjects were permitted only light activities except prescribed activities. In a separate group of 41 adults, free-living PAL was evaluated using doubly-labeled water (DLW. In both experiments, step counts per day were also measured using an accelerometer. Results In the human calorimeter study, PAL and step counts were 1.42 ± 0.10 and 8,973 ± 543 steps/d (L-day, 1.82 ± 0.14 and 29,588 ± 1,126 steps/d (M-day, and 1.74 ± 0.15 and 23,755 ± 1,038 steps/d (V-day, respectively. In the DLW study, PAL and step counts were 1.73 ± 0.15 and 10,022 ± 2,605 steps/d, and there was no significant relationship between PAL and daily step counts. Conclusions These results indicate that an enormous number of steps are needed for an active level of PAL if individuals extend physical activity-induced energy expenditure by only locomotive activity. Therefore, non-locomotive activity such as household activity should also play a significant role in increasing PAL under free-living conditions.

    Obesity and non-insulin dependent diabetes mellitus (NIDDM) are common in the Third Age and increasing in Cuba. Among the life-style changes associated with increased prevalence of obesity and its related disorders, diet and activity patterns are prime candidates. The transition to this life-style model may induce a decrease in the energy needs. There is an urgent need for tools which have been validated for measuring diet and physical activity in nutritional studies in the developing world, but also a more urgent need for reference values for the total energy requirements of healthy elderly people. Regular physical activity reduces the likelihood to develop diseases that characterise the metabolic cardiovascular syndrome. Previous studies done in Havana showed values of physical activity level (PAL) which are lower than the reported for elderly subjects. Elderly people living in rural areas use to have physical activity levels which differ from the observed in urban areas. With the purpose of estimating the energy requirements, a group of 40 apparently healthy people older than 60 years of age living in a rural mountain community will be submitted to a medical, epidemiological, dietary, anthropometric and insulin resistance study. Physical activity will be determined by questionnaire and by the calculation of the PAL from the basal metabolic rate (BMR) and total energy expenditure (TEE) measured with the doubly-labelled water method (DLW). Associations with the prevalence of insulin resistance and obesity will be assessed. (author)

    A number of international bodies have attempted to stimulate wider interest in Quality Assurance in X-ray departments. A major initiative has been taken by WHO with the publication of its recommendations in 1982 under the title Quality Assurance in Diagnostic Radiology, in which they indicated the action that should be taken at various national, professional and local levels. The recommendations of ICRP in Publication 26 point to the need for quality assurance programmes that will obtain optimum diagnostic information at minimum cost and minimum patient dose. ICRU have been considering the need for cost-effective quality assurance programmes and the specification of standards for image quality. The IEC and various manufacturers' organisations have begun to consider the part they can play in setting up quality control procedures. The most active group has been the ISRRT, which has arranged a series of seminars and workshops for radiographers in various parts of the world. Future needs for international support lie in the provision of training programmes, the publication of comparative statistical data and the development of image quality standards. (author)

    The purpose of this study was to examine (a) the effects of three curricular activities on students'situational motivation (intrinsic motivation [IM], identified regulation [IR], external regulation, and amotivation [AM]) and physical activity (PA) levels, and (b) the predictive strength of situational motivation to PA levels. Four hundred twelve students in grades 7-9 participated in three activities (cardiovascular fitness, ultimate football, and Dance Dance Revolution [DDR]) in physical education. ActiGraph GT1M accelerometers were used to measure students' PA levels for three classes for each activity. Students also completed a Situational Motivation Scale (Guay, Vallerand, & Blanchard, 2000) at the end of each class. Multivariate analysis of variance revealed that students spent significantly higher percentages of time in moderate-to-vigorous PA (MVPA) in fitness and football classes than they did in DDR class. Students reported higher lM and IR toward fitness than DDR They also scored higher in IR toward fitness than football. In contrast, students displayed significantly lower AM toward fitness than football and DDR Hierarchical Linear Modeling revealed that IM was the only positive predictor for time in MVPA (p = .02), whereas AM was the negative predictor (p < .01). The findings are discussed in regard to the implications for educational practice.

    Full Text Available This study reports on an exploratory research study that examined the design of websites that encourage both learning and enjoyment. This study examines museum websites that offer educational materials. As part of their mission, most museums provide the general public with educational materials for study and enjoyment. Many museums use the Internet in support of their mission. Museum websites offer excellent opportunity to study learning environments designed for enjoyment. Computer-supported learning of various types has been studied over the years, including computer-aided learning, computer-aided instruction, computer-managed learning, and more recently, learning via the Internet. Some relevant work appears in the literature on pleasure; however, the concept of online learning for enjoyment – specifically when learning is not part of a formal instructional undertaking – has not been well studied and thus is not well understood. This study seeks to redress this gap in the literature, specifically ‘learning for enjoyment,’ by reporting on a number of semi-structured in-depth interviews with museum and educational experts in Taiwan. Our study identified a number of characteristics required of online learning websites, and we conclude some suggested guidelines for developing an online learning website for enjoyment.

We sought to evaluate the effect of NRA on music enjoyment. Prospective analysis of music enjoyment. Academic medical center. Normal-hearing (NH) adults (N = 16) and CI listeners (N = 9). Subjective rating of music excerpts. NH and CI listeners evaluated country music piece on three enjoyment modalities: pleasantness, musicality, and naturalness. Participants listened to the original version and 20 modified, less complex versions created by including subsets of musical instruments from the original song. NH participants listened to the segments through CI simulation and CI listeners listened to the segments with their usual speech processing strategy, with and without NRA. Decreasing the number of instruments was significantly associated with increase in the pleasantness and naturalness in both NH and CI subjects (p  0.05): this was true for the original and the modified music segments with one to three instruments (p > 0.05). NRA does not affect music enjoyment in CI listener or NH individual with CI simulation. This suggests that strategies to enhance speech processing will not necessarily have a positive impact on music enjoyment. However, reducing the complexity of music shows promise in enhancing music enjoyment and should be further explored.

NH participants listened to the segments both with and without CI simulation processing. Results. Compared to the original song, modified versions containing only 1–3 instruments were less enjoyable to the NH listeners but more enjoyable to the CI listeners and the NH listeners with CI simulation. Excluding vocals and including rhythmic instruments improved enjoyment for NH listeners with CI simulation but made no difference for CI listeners. Conclusions. Reengineering a piece of music to reduce its complexity has the potential to enhance music enjoyment for the cochlear implantee. Thus, in addition to improvements in software and hardware, engineering music specifically for the CI listener may be an alternative means to enhance their listening experience.

    Why are negative emotions so central in art reception far beyond tragedy? Revisiting classical aesthetics in the light of recent psychological research, we present a novel model to explain this much discussed (apparent) paradox. We argue that negative emotions are an important resource for the arts in general, rather than a special license for exceptional art forms only. The underlying rationale is that negative emotions have been shown to be particularly powerful in securing attention, intense emotional involvement, and high memorability, and hence is precisely what artworks strive for. Two groups of processing mechanisms are identified that conjointly adopt the particular powers of negative emotions for art's purposes. The first group consists of psychological distancing mechanisms that are activated along with the cognitive schemata of art, representation, and fiction. These schemata imply personal safety and control over continuing or discontinuing exposure to artworks, thereby preventing negative emotions from becoming outright incompatible with expectations of enjoyment. This distancing sets the stage for a second group of processing components that allow art recipients to positively embrace the experiencing of negative emotions, thereby rendering art reception more intense, more interesting, more emotionally moving, more profound, and occasionally even more beautiful. These components include compositional interplays of positive and negative emotions, the effects of aesthetic virtues of using the media of (re)presentation (musical sound, words/language, color, shapes) on emotion perception, and meaning-making efforts. Moreover, our Distancing-Embracing model proposes that concomitant mixed emotions often help integrate negative emotions into altogether pleasurable trajectories.

  1. Sex Feel Good: Enjoyment of Sexual Intercourse by Some Barbadian Teenagers

    Full Text Available Within Caribbean societies and Barbados in particular issues on human sexuality are approached from a pathological, controlling, and judgmental perspective. These views resist an acknowledgment that children are sexual beings which manifestations are more evident during the teen years. Despite societal resistance, teenage pregnancies and sexual abuse forced societies to deal even if reluctantly with teenage sexuality. Based on Caribbean conservative approach to matters around sexuality it comes as no surprise that concerns around teenage sexuality is concentrated within discussions, discourses and scholarship about reproductive health, sexual abuse and sexually transmitted diseases. Based on the literature researched for Barbados and the rest of the Caribbean teenage sexual desire, and pleasurable sexual intercourses are virtually none-existent. It is the intention with this paper to contribute to scholarship on teenage sexual pleasure within Barbadian society. For its analysis the paper will utilize data collected from a teen sexuality research done during 2011-2012 among two secondary schools in Barbados. The main objective is to demonstrate that Barbadian teenagers are involved and enjoying sexual intercourse and other sexually related activities despite hegemonic discourses of sexual repression and control.

    The aim of this study was to evaluate the effects of a standardized exercise program on sports enjoyment and leisure-time spending in adolescents with congenital heart disease and to know what the moderating impact of their baseline health behavior and disease knowledge is. Included were 93 patients, aged 10 to 25, with surgical repair for tetralogy of Fallot or with a Fontan circulation for single-ventricle physiology, of 5 participating centers of pediatric cardiology in The Netherlands. They were randomly allocated, stratified for age, gender, and type of congenital heart disease to a 12-week period with either: (1) three times per week standardized exercise training or (2) care as usual (randomization ratio 2:1). At baseline and after 12 weeks, participants completed Web-based questionnaires and were interviewed by phone. Primary analyses tested changes from baseline to follow-up in sports enjoyment and leisure-time spending in the exercise group vs. control group. Secondary analyses concerned the moderating influence of baseline health behavior and disease knowledge on changes from baseline to follow-up, and comparison with normative data. At follow-up, the exercise group reported a decrease in passive leisure-time spending (watching television and computer usage) compared with controls. Exercise training had no effect on sports enjoyment and active leisure-time spending. Disease knowledge had a moderating effect on improvement in sports enjoyment, whereas health behavior did not. Compared with normative data, patients obtained similar leisure time scores and lower frequencies as to drinking alcohol and smoking. Exercise training decreased passive, but not active, leisure-time spending. It did not influence sports enjoyment. © 2013 Wiley Periodicals, Inc.

  6. Interactive video game cycling leads to higher energy expenditure and is more enjoyable than conventional exercise in adults.

    Directory of Open Access Journals (Sweden)

    Javier Monedero

    Full Text Available Despite the widely accepted health benefits of regular physical activity, only a small percentage of the population meets the current recommendations. The reasons include a wide use of technology and a lack of enjoyment while exercising. The purpose of this study was to compare the physiological, perceptual and enjoyment responses between a single bout of (I conventional cycling and (II interactive cycling video game at a matched workload.A cross-sectional study in 34 healthy participants was performed. Initially, participants completed an incremental maximal cycling test to measure peak oxygen uptake and to determine ventilatory threshold. In random order, participants carried out a 30 min interactive cycling trial and a 30 min conventional cycling trial at 55% of peak power output. During the trials, oxygen uptake and energy expenditure were measured by open-circuit spirometry and heart rate was measured by radiotelemetry. RPE and enjoyment were measured every 10 minutes with Borg scale and a modified PACES scale.Interactive cycling resulted in a significantly greater %V̇O2Reserve (68.2% ± 9.2% vs 64.7% ± 8.1%, rate of energy expenditure (505.8±75.2 vs 487.4±81.2 j·kg-1·min-1, and enjoyment (63.4% ± 17 vs 42% ± 13.6, P<0.05. Participants were working at a higher intensity in relation to the individual's ventilatory threshold during the interactive cycling video game trial (M = 11.86, SE = 3.08 than during the Conventional cycling trial (M = 7.55, SE = 3.16, t(33 = -2.69, P<0.05, r = .42. No significant differences were found for heart rate reserve (72.5 ± 10.4 vs 71.4±10.1% and RPE (13.1 ± 1.8 vs 13.2 ± 1.7.Interactive cycling games can be a valid alternative to conventional exercise as they result in a higher exercise intensity than conventional cycling and a distraction from aversive cognitive and physiological states at and above the ventilatory threshold.

    To examine the associations between three key developmental assets and an aspect of sexual health, sexual enjoyment, which has rarely been studied in young adults, although its importance is stressed in all recent sexual health policy statements. Using data from wave III (2001-2002) of the National Longitudinal Study of Adolescent Health, and multiple logistic and ordered logistic regression, we explored the associations between sexual pleasure and autonomy, self-esteem, and empathy among 3,237 respondents aged 18-26 years in heterosexual relationships of ≥ 3-month duration. We also examined the distribution of sexual pleasure across various socio-demographic groups. Compared with young women, young men reported more regular orgasms and more enjoyment of two kinds of partnered sexual behavior. Sexual enjoyment was not associated with age, race/ethnicity, or socioeconomic status. Among women, autonomy, self-esteem, and empathy co-varied positively with all three sexual enjoyment measures. Among men, all associations were in the same direction, but not all were statistically significant. A substantial gender difference in enjoyment of partnered sexual behavior exists among emerging adults in the United States. This study is the first to use a representative population sample to find a relationship between developmental assets and a positive aspect of sexual health - sexual pleasure.

  8. Are Volunteer Satisfaction and Enjoyment Related to Cessation of Volunteering by Older Adults?

    Science.gov (United States)

    Okun, Morris; Infurna, Frank J; Hutchinson, Ianeta

    2016-05-01

    Previous research indicates that volunteer satisfaction and enjoyment do not exert direct effects on the cessation of volunteering by older adults. This study examined whether satisfaction with and enjoyment of volunteering indirectly affect volunteer cessation via hours volunteered. Our sample consisted of participants in the Americans' Changing Lives study (N = 380) who were 65 years old and older and who volunteered at Wave 1. Volunteer satisfaction, volunteer enjoyment, hours volunteered, and several covariates were assessed at Wave 1, and volunteer cessation was assessed 3 years later at Wave 2. Volunteer satisfaction and volunteer enjoyment were positively associated with hours volunteered, and more hours volunteered was associated with decreased likelihood of volunteer cessation. The indirect effects of volunteer satisfaction and volunteer enjoyment on volunteer cessation via hours volunteered were -.023 (p = .059) and -.036 (p = .015), respectively. The dynamics of volunteer cessation are important because a volunteer shortage is forecasted and because the benefits of volunteering may attenuate when volunteering stops. Future research should test the proposed causal sequence using longitudinal data with at least 3 waves. © The Author 2014.

    2011-06-01

    Many studies have investigated how different technological features impact the experience of playing video games, yet few have focused on how control schemes may affect the play experience. This research employed a between-subjects design to explore the relationship between the type of console played (Nintendo Wii, Playstation 2) and feelings of flow and enjoyment during the game-play experience. Results indicated that participants reported greater feelings of control and enjoyment with a traditional control scheme (Playstation 2) than with the more technologically advanced control scheme (Nintendo Wii). Further mediation analysis showed that enjoyment was driven by the sense of control that participants experienced and not simply by whether they won the game. Theoretical and practical implications are discussed.

    Online activity could serve in the future as behavioral markers of emotional states for computer systems (i.e., affective computing). Hence, this study considered relationships between self-reported stimulant use and online study patterns. Sixty-two undergraduate psychology students estimated their daily caffeine use, and this was related to study patterns as tracked by their use of a Learning Management System (Blackboard). Caffeine dependency was associated with less time spent online, lower rates of file access, and fewer online activities completed. Reduced breadth or depth of processing during work/study could be used as a behavioral marker of stimulant use.

    A disc method has been widely used to measure the antibacterial effect of chemical agents. However, it is difficult to measure the antibacterial effect of radioisotopes using a disc method. A disc method is a method for diffusing a drug by placing the drug containing disc on the medium. In this method, radioisotopes are diffused on the medium and it is difficult to measure the exact effect by radiation. Thus, new laboratory equipment needs to evaluate the antibacterial activity by the radioisotopes. In this study, we measured the radiation level of radioisotopes on a new laboratory instrument using a MCNP. A disc method has been widely used to measure the antibacterial effect of chemical agents. This method uses a drug diffusion system for the measurement of anti-bacterial antibiotics. To measure the antimicrobial activity of a radioisotope, a new type of laboratory instrument is necessary to prevent the drug from spreading. The radioisotopes are used to diagnose and treat cancer. However, studies for anti-biotical use have not progressed. The radiation of radioisotopes has the effect of killing bacteria. Before this study proceeds further, it is necessary to be able to measure the antimicrobial activity of the radioisotope easily in the laboratory. However, in this study, it was possible to measure the antimicrobial activity of the radioisotope in the laboratory using a new laboratory instrument. We intend to start evaluation studies of the antibacterial activity of specific radioisotopes. In addition, it will be possible to develop research to overcome diseases caused by bacteria in the future

    Obesity and NIDDM are common in the Third Age and increasing in Cuba. Among the life-style changes associated with increased prevalence of obesity and its related disorders, diet and activity patterns are prime candidates. The transition to this life-style model may induce a decrease in the energy needs. There is an urgent need for tools which have been validated for measuring diet and physical activity in nutritional studies in the developing world, but also a more urgent need for reference values for the total energy requirements of healthy elderly people. Regular physical activity reduces the likelihood to develop diseases that characterise the metabolic cardiovascular syndrome. With the purpose of estimating the energy requirements, a group of 48 elderly people aged 61-74 years living in a rural mountain community was submitted to a medical, epidemiological, dietary and biochemical study of the nutritional status. Glucose intolerance was diagnosed in 40% and arterial hypertension was present in 23 of them. Ten subjects without signs or symptoms of the metabolic cardiovascular syndrome were submitted to a measurement of the total energy expenditure by the doubly labelled water method. PAL values of 2.13 and 1. 77 were measured for men and women, values which were significantly higher that the recommended value of 1.51 for elderly subjects. The estimation of energy requirements by the energy intake or by the factorial method using the physical activity questionnaires generated values, which were 11% and 30% lower than the values obtained by the DLW-method The value of 1.51 x BMR for the estimation of the energy requirements of elderly subjects living in rural areas and submitted to higher levels of physical activity seems to be sub estimated.

    To better understand the role of motivation in determining exercise participation at the population level, we performed a questionnaire survey of 385 Japanese adults (mean age: 55.0 years, SD: 10.9 years). At baseline, the motivation subscales (intrinsic motivation, identified regulation, and external regulation), self-efficacy, and enjoyment all showed significant differences across the stages of change for exercise. Intrinsic motivation and enjoyment had similar findings, with the highest scores being noted in the maintenance stage. Among the 385 subjects, 183 completed the follow-up questionnaire 3 months later. After 3 months, most of the participants (86.9%) who were in the maintenance stage at baseline remained in the same stage. The number of participants who dropped to a lower stage after 3 months was 23. The changes of exercise stage over the 3-month period differed significantly for identified regulation, introjected regulation, and motivation. There were significant time and group interactions for intrinsic motivation and identified regulation. These findings suggest the importance of intrinsic motivation and identified regulation for performance of regular exercise, as well as the role of introjected regulation for promoting behavioral change among Japanese adults.

    This study, based on the theory of deliberate practice, examined the practice relevance, effort, and inherent enjoyment aspects of the theory. 25 college undergraduates practiced playing a melody on an electronic keyboard for three 20-min. practice sessions. Following each session, the perceived relevance of the practice for improving performance of the melody, the effort needed to learn the melody, and the inherent enjoyment of the practice were each rated on 10-point scales. Findings were consistent with theory and similar to previous studies also involving music practice and other tasks.

  11. Does regional disadvantage affect health-related sport and physical activity level? A multi-level analysis of individual behaviour.

    Science.gov (United States)

    Wicker, Pamela; Downward, Paul; Lera-López, Fernando

    2017-11-01

    This study examines the role of regional government quality in health-related participation in sport and physical activity among adults (18-64 years) in 28 European countries. The importance of the analysis rests in the relative autonomy that regional and local governments have over policy decisions connected with sport and physical activity. While existing studies have focussed on economic and infrastructural investment and expenditure, this research investigates the quality of regional governments across 208 regions within 28 European countries. The individual-level data stem from the 2013 Eurobarometer 80.2 (n = 18,675) and were combined with regional-level data from Eurostat. An individual's level of participation in sport and physical activity was measured by three variables reflecting whether an individual's activity level is below, meets, or exceeds the recommendations of the World Health Organization. The results of multi-level analyses reveal that regional government quality has a significant and positive association with individual participation in sport and physical activity at a level meeting or exceeding the guidelines. The impact is much larger than that of regional gross domestic product per capita, indicating that regional disadvantage in terms of political quality is more relevant than being disadvantaged in terms of economic wealth.

    This work presents The results of the eco toxicological characterisation of 22 defined wastes from steel foundry activities. The wastes have been selected from three processes, steel mill (smelting). sand casting and cleaning and finishing of steel products,with the common characteristics of represent an important industrial activity in the area and generated the wastes considered in this study. The eco toxicological characterisation obtained applying the Spanish regulations on hazardous waste is compared to the hazardous attributions considered by the European Union in order to characterise a waste as hazardous (non hazardous). The results allow to conclude that a acceptable concordance between both methodologies is reached and remark the need to split the broad generic types of wastes given by the Spanish regulation (Eco toxic / non eco toxic) into clearly identifiable specific types of waste

  13. Effect of physical activity on anxiety levels in pregnant women

    Full Text Available Pregnancy is a very important period in a woman's life, but it is often associated not only with positive emotions, but also with negative emotions such as anxiety, stress or depression. Women most often fear birth and various medical complications during pregnancy. Very often their unpleasant experiences at the beginning such as nausea, fatigue and strong anxiety cause them to give up their physical activity. Numerous studies show that the physical activity of pregnant women has a positive impact on mother and child health. First and foremost, it is a powerful preventive agent in cardiovascular disease, diabetes mellitus, but also has a beneficial effect on the well-being of future mothers, including lowering anxiety and lowering the incidence of postpartum depression. That is why it is so important to educate pregnant women what exercises are most beneficial for them.

    Coastal habitats are vulnerable to storms, and with increasing urbanization, sea level rise, and storm frequency, some urban populations are at risk. This study examined perceptions of respondents in coastal and central New Jersey to Superstorm Sandy , including: 1) concerns about ecological resources and effects (open-ended question), 2) information sources for ecology of the coast (open-ended), and 3) ratings of a list of ecological services as a function of demographics, location (coastal, central Jersey), stressor level (power outages, high winds, flooding) and recreational rates. "Wildlife" and "fish" were the ecological concerns mentioned most often, while beaches and dunes were most often mentioned for environmental concerns. Television, radio, and web/internet were sources trusted for ecological information. The data indicate 1) stressor level was a better predictor of ratings of ecological services than geographical location, but days engaged in recreation contributed the most to variations in ratings, 2) ecological services were rated the highest by respondents with the highest stressor levels, and by those from the coast, compared to others, 3) Caucasians rated ecological services higher than all others, and 4) recreational rates were highest for coastal respondents, and ratings for ecological services increased with recreational rates. Only 20 % of respondents listed specific ecological services as one of their three most important environmental concerns. These data will be useful for increasing preparedness, enhancing educational strategies for shore protection, and providing managers and public policy makers with data essential to developing resiliency strategies.

    Biosensors based on silicon photonic integrated circuits have attracted a growing interest in recent years. The use of sub-micron silicon waveguides to propagate near-infrared light allows for the drastic reduction of the optical system size, while increasing its complexity and sensitivity. Using silicon as the propagating medium also leverages the fabrication capabilities of CMOS foundries, which offer low-cost mass production. Researchers have deeply investigated photonic sensor devices, such as ring resonators, interferometers and photonic crystals, but the practical integration of silicon photonic biochips as part of a complete system has received less attention. Herein, we present a practical system-level architecture which can be employed to integrate the aforementioned photonic biosensors. We describe a system based on 1 mm2 dies that integrate germanium photodetectors and a single light coupling device. The die are embedded into a 16x16 mm2 epoxy package to enable microfluidic and electrical integration. First, we demonstrate a simple process to mimic Fan-Out Wafer-level-Packaging, which enables low-cost mass production. We then characterize the photodetectors in the photovoltaic mode, which exhibit high sensitivity at low optical power. Finally, we present a new grating coupler concept to relax the lateral alignment tolerance down to +/- 50 μm at 1-dB (80%) power penalty, which should permit non-experts to use the biochips in a"plug-and-play" style. The system-level integration demonstrated in this study paves the way towards the mass production of low-cost and highly sensitive biosensors, and can facilitate their wide adoption for biomedical and agro-environmental applications.

    1987-01-01

    The Maxey Flats Radioactive Waste Disposal Facility in Fleming County, Kentucky is in the process of being closed. The facility opened for commercial business in the spring of 1963 and received approximately 4.75 million cubic feet of radioactive waste by the time it was closed in December of 1977. During fourteen years of operation approximately 2.5 million curies of by-product material, 240,000 kilograms of source material, and 430 kilograms of special nuclear material were disposed. The Commonwealth purchased the lease hold estate and rights in May 1978 from the operating company. This action was taken to stabilize the facility and prepare it for closure consisting of passive care and monitoring. To prepare the site for closure, a number of remedial activities had to be performed. The remediation activities implemented have included erosion control, surface drainage modifications, installation of a temporary plastic surface cover, leachate removal, analysis, treatment and evaporation, US DOE funded evaporator concentrates solidification project and their on-site disposal in an improved disposal trench with enhanced cover for use in a humid environment situated in a fractured geology, performance evaluation of a grout injection demonstration, USGS subsurface geologic investigation, development of conceptual closure designs, and finally being added to the US EPA National Priority List for remediation and closure under Superfund. 13 references, 3 figures

  19. Assessment of allowable transuranic activity levels for WIPP wastes

    International Nuclear Information System (INIS)

    1987-12-01

    This study provides a technical evaluation for the establishment of an upper limit on the transuranic content of waste packages to be received. To accomplish this, the predicted radiological performance of WIPP is compared to the radiological performance requirements applicable to WIPP. These performance requirements include radiation protection standards for both routine facility operations and credible operational accidents. These requirements are discussed in Chapter 2.0. From the margin between predicted performance and the performance requirements, the maximum allowable transuranic content of waste packages can then be inferred. Within the resulting compliance envelope, a waste acceptance criterion can be established that delineates the allowable level of transuranic radioactivity content for contact handled (CH) and remote handled (RH) waste packages. 13 refs., 8 tabs

  9. Love and enjoyment in context: Four case studies of adolescent EFL learners

    Directory of Open Access Journals (Sweden)

    Liana Maria Pavelescu

    2018-03-01

    Full Text Available This study explores the foreign language learning emotions of four EFL adolescent students in Romania and the ways in which their emotions emerge in their sociocultural context. Multiple qualitative methods were employed over a school semester, including a written task, semi-structured interviews with the learners and their teachers, lesson observations and English-related events outside the classroom. It was found that, while all four participants reported experiencing positive emotions in language learning, a distinction was identified in the intensity and stability of their emotions. Two participants expressed a strong and stable emotion of love towards English, while the other two participants experienced enjoyment in their English language learning without an intense emotional attachment to English. Unlike enjoyment, love was found to be the driving force in the learning process, creating effective coping mechanisms when there was a lack of enjoyment in certain classroom situations and motivating learners to invest greater effort into language learning in and out of the classroom. The findings thus revealed that, unlike enjoyment, love broadened cognition and maintained engagement in learning. The study emphasizes the role of strong, enduring positive emotions in teenage students’ language learning process.

    The proposed model overlooks the contribution of a relational/prosocial dimension to the enjoyment of negative emotion in art reception. Negative experiences have a unique capacity to build social bonds and may also increase motivation to "connect" with the artist. This affiliative motivation ensures that people experience an artwork as more emotional, more intense, more interesting, and ultimately more rewarding.

    Poschner, J.; Schaller, G.

    1993-12-01

    Using radioecological models, nuclide-specific ''basic values'' were established for the specific activity of radioactive contaminated waste. These basic values were determined in order to avoid dose equivalents of more than 10 μSv/a (de minimis concept) when disposing the waste in conventional waste deposits or burning it in incineration plants. The basic values vary within 16 orders of magnitude, ranging between 4.3E-02 Bq/g for Cm-250 and 2.2E+14 Bq/g for Po-212. About 82% of the basic values are between 1 Bq/g und 1000 Bq/g. The critical exposure for most of the radionuclides is that from direct radiation or inhalation at the slag-deposit. For 54% of the radionuclides the basic value for the specific activity of waste is lower at least by a factor of 10 than the 10 -4 -fold value per gram of the release limit (German Radiation Protection Ordinance). Appropriate nuclide-specific and dose-related limits were derived from these basic values. The respective limits are ranging between 1E-01 Bq/g and 1E+07 Bq/g. About 95% of the limits are between 1 Bq/g and 1000 Bq/g. (orig./HP) [de

    Using radioecological models, nuclide specific values were calculated for the specific activity of low contaminated radioactive waste, which is disposed in conventional waste deposits or burned in incineration plants. The calculation of these values is based on a limit of 10 μSv effective dose in one year, i.e. effective dose possibly resulting from waste disposal or burning should not exceed a 'de-minimis'-value of some 10 μSv per year. The applied radioecological models describe exposure of the public by direct radiation, inhalation and ingestion for the operational period of a deposit or an incineration plant, but also cover post-operational scenarios, collecting and sorting of waste and road accidents of the waste-truck. Referring to the dose limit of 10 μSv/a, a value for the specific activity of waste was calculated for each scenario and each radionuclide considered. The smallest of these values for a radionuclide, the 'basic value' was rounded to a 'reference value'. For about 600 radionuclides reference values were derived. About 90% of the reference values are ranging between 1 and 1 000 Bq/g. For about 90% of the radionuclides direct radiation or inhalation at the deposit proved to be the critical path of exposure.

    Physical activity affects the pain symptoms for Achilles tendinosis patients. Brain-derived neurotrophic factor (BDNF), tumor necrosis factor-alpha (TNF-α) and their receptors have been detected in human Achilles tendon. This pilot study aimed to compare serum BDNF and soluble tumor necrosis factor receptor I (sTNFRI) levels in Achilles tendinosis patients and healthy controls and to examine the influence of physical activity, and BMI and gender, on these levels. Physical activity was measured with a validated questionnaire, total physical activity being the parameter analyzed. Physical activity was strongly correlated with BDNF among tendinosis women [Spearman's rho (ρ)=0.90, Pwomen (ρ=-0.08, P=0.83), or among tendinosis and control men. Physical activity was significantly correlated with sTNFRI in the entire tendinosis group and among tendinosis men (ρ=0.65, P=0.01), but not in the entire control group or among control men (ρ=0.04, P=0.91). Thus, the physical activity pattern is related to the TNF and BDNF systems for tendinosis patients but not controls, the relationship being gender dependent. This is new information concerning the relationship between physical activity and Achilles tendinosis, which may be related to pain for the patients. This aspect should be further evaluated using larger patient materials. © 2011 John Wiley & Sons A/S.

  1. The effects of gamelike features and test location on cognitive test performance and participant enjoyment

    Jim Lumsden

    2016-07-01

    Full Text Available Computerised cognitive assessments are a vital tool in the behavioural sciences, but participants often view them as effortful and unengaging. One potential solution is to add gamelike elements to these tasks in order to make them more intrinsically enjoyable, and some researchers have posited that a more engaging task might produce higher quality data. This assumption, however, remains largely untested. We investigated the effects of gamelike features and test location on the data and enjoyment ratings from a simple cognitive task. We tested three gamified variants of the Go-No-Go task, delivered both in the laboratory and online. In the first version of the task participants were rewarded with points for performing optimally. The second version of the task was framed as a cowboy shootout. The third version was a standard Go-No-Go task, used as a control condition. We compared reaction time, accuracy and subjective measures of enjoyment and engagement between task variants and study location. We found points to be a highly suitable game mechanic for gamified cognitive testing because they did not disrupt the validity of the data collected but increased participant enjoyment. However, we found no evidence that gamelike features could increase engagement to the point where participant performance improved. We also found that while participants enjoyed the cowboy themed task, the difficulty of categorising the gamelike stimuli adversely affected participant performance, increasing No-Go error rates by 28% compared to the non-game control. Responses collected online vs. in the laboratory had slightly longer reaction times but were otherwise very similar, supporting other findings that online crowdsourcing is an acceptable method of data collection for this type of research.

    Affective response during physical activity may influence motivation to perform future physical activity behavior. However, affective response during physical activity is often assessed under controlled laboratory conditions. The current study used ecological momentary assessment (EMA) to capture affective responses during free-living physical activity performed by adults, and determined whether these affective responses predict future moderate-to-vigorous physical activity (MVPA) levels after 6 and 12 months. At baseline, electronic EMA surveys were randomly prompted across 4 days asking about current activities and affective states (e.g., happy, stressed, energetic, tired). Affective response during physical activity was operationalized as the level of positive or negative affect reported when concurrent physical activity (e.g., exercise or sports) was also reported. Data were available for 82 adults. Future levels of moderate-to-vigorous physical activity (MVPA) were measured using accelerometers, worn for seven consecutive days at 6 and 12 months after the baseline assessment. Feeling more energetic during physical activity was associated with performing more minutes of daily MVPA after both 6 and 12 months. Feeling less negative affect during physical activity was associated with engaging in more daily MVPA minutes after 12 months only. This study demonstrated how EMA can be used to capture affective responses during free-living physical activity. Results found that feelings more energetic and less negative during physical activity were associated with more future physical activity, suggesting that positive emotional benefits may reinforce behavior.

    Participation is an important modifiable quality of life (QOL) determinant and a key outcome measure. The aim of this study was to confirm if participation in leisure activities affects the QOL domains in children and adolescents with Cerebral Palsy (CP) in Spain. A total of 206 children and adolescents with CP (and their parents), 115 boys and 91 girls, mean age of 11.96 years (SD=3.00; range 8-18 years) participated in the study. Distribution according to the Gross Motor Function Classification System (GMFCS) was 24.3% Level I, 18% Level II, 18% Level III, 12.6% Level IV, and 27.2% Level V. Participation in leisure activities was assessed using the Spanish version of Children's Assessment of Participation and Enjoyment (CAPE) and QOL using the KIDSCREEN parents' version. Diversity, intensity and enjoyment of participation explained the levels of QOL in the Physical well-being, Psychological well-being, Autonomy, Parent relation & home life and Social support & peers domains, independently of gender, age and level of impairment (motor and intellectual). We also found that intensity and enjoyment of participation in informal activities had more influence on the different QOL domains. The most influenced domain by the enjoyment of participation in all domains and types of CAPE activities was Psychological well-being. The participation in leisure activities had a positive effect on the QOL of the Spanish children and adolescents with CP. Copyright © 2013 Elsevier Ltd. All rights reserved.

  12. Enjoyment and its discontents: Ecclesiastes in dialogue with Freud on the stewardship of joy.

    Science.gov (United States)

    Browning Helsel, Philip

    2010-03-01

    The book of Ecclesiastes has frequently been mischaracterized as a cynical or pessimistic work. Instead, this article recommends Ecclesiastes, following Eunny P. Lee, as contributing to pastoral theology through its embodied and pragmatic theology of enjoyment in which practices of joy revitalize the human spirit. However, there are some who are unable to experience satisfaction. The absence of reflection on this problem in Ecclesiastes scholarship is considered the starting point of pastoral theology, and is addressed by a turn to the frequently misunderstood passage in 7:16-18, bringing it into conversation with the structural [corrected] model of the human person developed by Freud. At the same time, the interpersonal aspects of enjoyment found in Ecclesiastes critique Freud by suggesting how the fragmented parts of self-experience can be held together in an interpersonal context.

    Full Text Available The recognition of adolescents’ physical activity has become one of the serious challenges of the modern times, as a concern about the future health of societies. The major goal of the presented study was to discover the level of physical activity among Polish adolescents aged 16–18, and the factors which condition this level. The investigations were carried out in 2011, among 2,974 school adolescents from various locations in Poland – 1,790 girls (60.2%, and 1,184 boys (39.8%. As a study method, a short version of the IPAQ was applied. The results of the study indicated that a larger number of girls than boys show a low level of physical activity. With respect to activity among boys, higher values of intensive and moderate efforts are noted, while in girls, higher values of activities related to walking. It was confirmed that the level of physical activity does not depend on the place of residence. However, the number of physical exercise classes attended is a significant factor, both among boys and girls. It was also found that adolescents who more frequently lead a sedentary style of life are characterized by a lower level of total physical activity. Sedentary lifestyle (time spent sitting does not differ among the level of physical activity of girls and of boys, neither with respect to the scope of the total physical activity nor to its three levels (low, moderate, high.

  19. Intermediate levels of hippocampal activity appear optimal for associative memory formation.

    Directory of Open Access Journals (Sweden)

    Xiao Liu

    Full Text Available BACKGROUND: It is well established that hippocampal activity is positively related to effective associative memory formation. However, in biological systems often optimal levels of activity are contrasted by both sub- and supra-optimal levels. Sub-optimal levels of hippocampal activity are commonly attributed to unsuccessful memory formation, whereas the supra-optimal levels of hippocampal activity related to unsuccessful memory formation have been rarely studied. It is still unclear under what circumstances such supra-optimal levels of hippocampal activity occur. To clarify this issue, we aimed at creating a condition, in which supra-optimal hippocampal activity is associated with encoding failure. We assumed that such supra-optimal activity occurs when task-relevant information is embedded in task-irrelevant, distracting information, which can be considered as noise. METHODOLOGY/PRINCIPAL FINDINGS: In the present fMRI study, we probed neural correlates of associative memory formation in a full-factorial design with associative memory (subsequently remembered versus forgotten and noise (induced by high versus low distraction as factors. Results showed that encoding failure was associated with supra-optimal activity in the high-distraction condition and with sub-optimal activity in the low distraction condition. Thus, we revealed evidence for a bell-shape function relating hippocampal activity with associative encoding success. CONCLUSIONS/SIGNIFICANCE: Our findings indicate that intermediate levels of hippocampal activity are optimal while both too low and too high levels appear detrimental for associative memory formation. Supra-optimal levels of hippocampal activity seem to occur when task-irrelevant information is added to task-relevant signal. If such task-irrelevant noise is reduced adequately, hippocampal activity is lower and thus optimal for associative memory formation.

    People often consume multiple products at the same time (e.g., chips and salsa). Four studies demonstrate that people enjoy such joint consumption experiences more when the products are merely labeled with the same brand (vs. different brands). Process evidence shows that this brand matching effect arises because matching brand labels cue consumers' belief that the two products were coordinated through joint testing and design to go uniquely well together. This shows that there is no universa...

    The use of faecal samples taken from sheep flocks as a means of predicting radiocaesium concentrations in live animals was studied. Radiocaesium levels in 1726 sheep from 29 flocks were measured using in vivo techniques and a single faecal sample taken from each flock was also analysed. A highly significant relationship was found to exist between mean flock activity and activity in the corresponding faecal samples. Least-square regression yielded a simple model for predicting mean flock radiocaesium concentrations based on activity levels in faecal samples. A similar analysis of flock maxima and activity levels in faeces provides an alternative model for predicting the expected within-flock maximum radiocaesium concentration. (Author)

    About half a billion people with disabilities in developing countries have limited access to assistive technology. The Convention on the Rights of persons with Disabilities requires governments to take measures to ensure provision of such technologies. To guide implementation of these measures there is a need for understanding health outcomes from a human rights perspective. The objective of this study was therefore to explore the relation between assistive technology use and enjoyment of human rights in a low-income country. Data was collected in eight districts of Bangladesh through interviews of people with hearing impairments using and not using hearings aids, and people with ambulatory impairments using and not using manual wheelchairs (N = 583). Using logistic regression, self-reported outcomes on standard of living, health, education, work, receiving information and movement were analyzed. The adjusted likelihood of reporting greater enjoyment of human rights was significantly higher among people using hearing aids compared to non-users for all outcomes except working status. Compared to non-users, users of wheelchairs reported a significantly higher adjusted likelihood of good ambulatory performance and a significantly lower adjusted likelihood of reporting a positive working status. Further analyses indicated that physical accessibility to working places and duration of wheelchair use had a statistically significant impact on the likelihood of reporting positive work outcomes. The findings support the notion that assistive technology use increases the likelihood of human rights enjoyment, particularly hearing aid use. Physical accessibility should always be addressed in wheelchair provision.

    Road accidents are an important public health concern, and speeding is a major contributor. Although flow theory (FLT) is a valid model for understanding behavior, currently the nature of the roles and interplay of FLT constructs within the theory of planned behavior (TPB) framework when attempting to explain the determinants of motivations for intention to speed and speeding behavior of car drivers is not yet known. The study aims to synthesize TPB and FLT in explaining drivers of advanced vehicles intentions to speed and speed violation behaviors and evaluate factors that are critical for explaining intention and behavior. The hypothesized model was validated using a sample collected from 354 fully licensed drivers of advanced vehicles, involving 278 males and 76 females on 2 occasions separated by a 3-month interval. During the first of the 2 occasions, participants completed questionnaire measures of TPB and FLT variables. Three months later, participants' speed violation behaviors were assessed. The study observed a significant positive relationship between the constructs. The proposed model accounted for 51 and 45% of the variance in intention to speed and speed violation behavior, respectively. The independent predictors of intention were enjoyment, attitude, and subjective norm. The independent predictors of speed violation behavior were enjoyment, concentration, intention, and perceived behavioral control. The findings suggest that safety interventions for preventing speed violation behaviors should be aimed at underlying beliefs influencing the speeding behaviors of drivers of advanced vehicles. Furthermore, perceived enjoyment is of equal importance to driver's intention, influencing speed violation behavior.

  5. The Role of Trait and State Absorption in the Enjoyment of Music

    2016-01-01

    Little is known about the role of state versus trait characteristics on our enjoyment of music. The aim of this study was to investigate the influence of state and trait absorption upon preference for music, particularly preference for music that evokes negative emotions. The sample consisted of 128 participants who were asked to listen to two pieces of self-selected music and rate the music on variables including preference and felt and expressed emotions. Participants completed a brief measure of state absorption after listening to each piece, and a trait absorption inventory. State absorption was strongly positively correlated with music preference, whereas trait absorption was not. Trait absorption was related to preference for negative emotions in music, with chi-square analyses demonstrating greater enjoyment of negative emotions in music among individuals with high trait absorption. This is the first study to show that state and trait absorption have separable and distinct effects on a listener’s music experience, with state characteristics impacting music enjoyment in the moment, and trait characteristics influencing music preference based on its emotional content.

    The purpose of this study was to assess the validity of the Human Activity Profile (HAP) by comparing scores with accelerometer data and by objectively testing its cutoff points. This study included 120 older women (age 60-90 years). Average daily time spent in sedentary, moderate, and hard activity; counts; number of steps; and energy expenditure were measured using an accelerometer. Spearman rank order correlations were used to evaluate the correlation between the HAP scores and accelerometer variables. Significant relationships were detected (rho = .47-.75, p < .001), indicating that the HAP estimates physical activity at a group level well; however, scatterplots showed individual errors. Receiver operating characteristic curves were constructed to determine HAP cutoff points on the basis of physical activity level recommendations, and the cutoff points found were similar to the original HAP cutoff points. The HAP is a useful indicator of physical activity levels in older women.

    Working mothers are less physically active than working women without children and mothers who do not work. The purpose of this study was to examine concurrent self-regulatory efficacy and barriers to physical activity in a sample of working mothers. Women completed a mixed-methods survey which included measures of physical activity, concurrent self-regulatory efficacy, and barriers. Sufficiently active women experienced significantly greater concurrent self-regulatory efficacy and significantly less barrier limitation and frequency. No significant group differences were found for age, domestic duties performed, and children's extracurricular activities. Thematic analysis of barriers revealed six themes of common and unique factors, including limited time and family activities. © The Author(s) 2014.

    Full Text Available Thrombotic thrombocytopenic purpura (TTP is a thrombotic microangiopathy characterized by endothelial cell damage, resulting in microangiopathic hemolytic anemia, thrombocytopenia, and various degrees of neurological and renal impairment caused by microvascular thrombi. It is rare in children and frequently follows a fatal course. TTP is divided into 2 types: one is inherited and associated with ADAMTS-13 gene mutations and the other is acquired and associated with anti-ADAMTS-13 autoantibodies. The measurement of ADAMTS-13 activity in plasma, identification of ADAMTS-13 circulating inhibitor, anti-ADAMTS-13 IgG, and ADAMTS-13 gene sequencing are crucial to the diagnosis of TTP. Plasma exchanges are the first-line treatment for acquired TTP, combined with steroids and immunosuppressive drugs. Here, we describe the case of an adolescent patient with TTP, confirmed by decreased level of ADAMTS-13 activity and an increased level of ADAMTS-13 inhibitor, who was successfully treated by plasma exchanges.

    2016-07-01

    Full Text Available To determine the impact of physical activity and fitness on the level of physical activity barriers (kinesiophobia in women of perimenopausal age, the study included 105 women between the ages of 48 and 58. A Baecke questionnaire was used to evaluate physical activity and a modified Fullerton test was used to evaluate the fitness level. The level of kinesiophobia was assessed using the Kinesiophobia Causes Scale questionnaire. A low level of habitual physical activity has a negative impact on the values of Biological Domain (r = –0.581, Psychological Domain (r = –0.451, and on the Kinesiophobia Cause Scale total score (r = –0.577. Lower physical activity expressed by a lower score in the Fullerton test also has a negative impact on the level of kinesiophobia. Upper body flexibility (r = –0.434 has the strongest influence on the Biological Domain, whereas upper body strength (r = –0.598 has the greatest impact on the Psychological Domain. A low level of upper body strength also has the greatest impact on the Kinesiophobia Cause Scale total score (r = –0.507. Low levels of physical activity and fitness in women of perimenopausal age favour kinesiophobic attitudes and thereby increase the level of barriers against undertaking physical activity.

    Evaluating the activity of the complement system under conditions of altered thyroid hormone levels might help elucidate the role of complement in triggering autoimmune processes. Here, we investigated alternative pathway (AP) activity in male Wistar rats (180 ± 10 g) after altering their thyroid hormone levels by treatment with triiodothyronine (T3), propylthiouracil (PTU) or thyroidectomy. T3 and thyroxine (T4) levels were determined by chemiluminescence assays. Hemolytic assays were performed to evaluate the lytic activity of the AP. Factor B activity was evaluated using factor B-deficient serum. An anti-human factor B antibody was used to measure factor B levels in serum by radial immunodiffusion. T3 measurements in thyroidectomized animals or animals treated with PTU demonstrated a significant reduction in hormone levels compared to control. The results showed a reduction in AP lytic activity in rats treated with increasing amounts of T3 (1, 10, or 50 µg). Factor B activity was also decreased in the sera of hyperthyroid rats treated with 1 to 50 µg T3. Additionally, treating rats with 25 µg T3 significantly increased factor B levels in their sera (P < 0.01). In contrast, increased factor B concentration and activity (32%) were observed in hypothyroid rats. We conclude that alterations in thyroid hormone levels affect the activity of the AP and factor B, which may in turn affect the roles of AP and factor B in antibody production.

    Full Text Available Several studies have investigated activity levels among adolescents, but no study has examined longitudinal changes in physical activity (PA level, body mass, and oxygen uptake among the same adolescents from the age of 14 to 19 years. The present study examined data from a research project that included a group of randomly selected students (N = 116 with objective measurements of PA (accelerometer data, self-reported PA level, and body mass and oxygen uptake during a 5-year period. The results show a significant decrease in the accelerometer-based PA level over time, from age 14 to 19. At 14 years of age, the minutes of moderate and/or vigorous PA was 66.7 min·day−1, but was less than half, at only 24.4 min·day−1, at 19 years of age. The self-reported activity data show a decrease in girls’ general activity level over time, while boys’ activity level during school breaks decreased strongly during the period: at age 14, 61% of the boys were classified as active, while at age 19, only 11% were physically active. Furthermore, body mass index increased during the period for both genders, while oxygen uptake decreased. Since both BMI and maximal oxygen uptake are important risk factors for future CVD, these findings point toward the importance of maintaining a high activity level during childhood and adolescence, in order to keep fit later in life.

Here, we investigated alternative pathway (AP) activity in male Wistar rats (180 ± 10 g) after altering their thyroid hormone levels by treatment with triiodothyronine (T3), propylthiouracil (PTU) or thyroidectomy. T3 and thyroxine (T4) levels were determined by chemiluminescence assays. Hemolytic assays were performed to evaluate the lytic activity of the AP. Factor B activity was evaluated using factor B-deficient serum. An anti-human factor B antibody was used to measure factor B levels in serum by radial immunodiffusion. T3 measurements in thyroidectomized animals or animals treated with PTU demonstrated a significant reduction in hormone levels compared to control. The results showed a reduction in AP lytic activity in rats treated with increasing amounts of T3 (1, 10, or 50 µg). Factor B activity was also decreased in the sera of hyperthyroid rats treated with 1 to 50 µg T3. Additionally, treating rats with 25 µg T3 significantly increased factor B levels in their sera (P < 0.01). In contrast, increased factor B concentration and activity (32%) were observed in hypothyroid rats. We conclude that alterations in thyroid hormone levels affect the activity of the AP and factor B, which may in turn affect the roles of AP and factor B in antibody production

    Physical activity unquestionably maintains and improves health; however, physical activity levels globally are low and not rising despite all the resources devoted to this goal. Attention in both the research literature and the public policy domain has focused on social-behavioral factors; however, a growing body of literature suggests that biological determinants play a significant role in regulating physical activity levels. For instance, physical activity level, measured in various manners, has a genetic component in both humans and nonhuman animal models. This consensus article, developed as a result of an American College of Sports Medicine-sponsored round table, provides a brief review of the theoretical concepts and existing literature that supports a significant role of genetic and other biological factors in the regulation of physical activity. Future research on physical activity regulation should incorporate genetics and other biological determinants of physical activity instead of a sole reliance on social and other environmental determinants.

    Active warning devices are effective in preventing accidents due to road user errors. Equipping the most dangerous passive level crossings with warning devices – low cost or conventional – would increase safety. Alternatively, some level crossings could be removed altogether. A minimum requirement is that the environmental factors at passive level crossings support safe crossing.

    Appropriate diet and physical activity are vital determinants of psychophysical development in children and adolescents. The aim of the study was to analyse an association between dietary habits and physical activity levels of adolescents from post-grammar schools. The study included 110 girls and 65 boys between 16 and 19 years of age from two post-grammar schools in Biała Podlaska in Poland. They were subjected to a diagnostic survey providing information on their diet (number of meals a day, their regularity, frequency of bread, dairy, meat, fish, sweet, fruit, vegetable and fast food consumption, preferred ways of food processing). Physical activity levels were determined with the International Physical Activity Questionnaire--Short Form (IPAQ-SF). Based on these data, the respondents were stratified to high, moderate and low physical activity groups. Due to small number of participants presenting with low physical activity levels, we did not include this group in further analyses. The significance of differences in the dietary habits of adolescents presenting with high and moderate physical activity levels was verified with the χ2 test. Most girls and boys presented with high levels of physical activity. However, we did not find an evident relationship between dietary habits and physical activity levels. Girls from high and moderate physical activity groups differed solely in terms of the number of daily meals, frequency of meat and sweet consumption, and significant intergroup differences observed among boys pertained to the frequencies of whole-wheat bread, meat and fast food consumption. The abovementioned food products were consumed more often by girls and boys presenting with high physical activity levels. The dietary mistakes observed in physically active adolescents from post-secondary schools justify intensification of their dietary education programs.

    Overexpression of matrix metalloproteinases (MMPs) has been associated with increased tumor aggressiveness and metastasis dissemination. We investigated whether the contrasting metastatic behavior of feline and canine osteosarcoma is related to levels and activities of MMP2 and MMP9. Zymography and immunohistochemistry were used to determine expression levels of MMP2 and MMP9 in canine and feline osteosarcoma. Using immunohistochemistry, increased MMP9 levels were identified in most canine osteosarcomas, whereas cat samples more often displayed moderate levels. High levels of pro-MMP9, pro-MMP2, and active MMP2 were detected by gelatin zymography in both species, with significantly higher values for active MMP2 in canine osteosarcoma. These findings indicate that MMP2 is probably involved in canine and feline osteosarcoma and their expression and activity could be associated with the different metastatic behavior of canine and feline osteosarcoma.

    Full Text Available Abstract Background The benefits of a recommended level of physical activity on physiological health indicators such as morbidity and mortality are well-accepted, but less research has addressed whether or not the association between the recommended level of physical activity and a health-related quality of life (HRQOL exists in the Japanese population. Thus, the present study examined whether the recommended physical activity would be associated with HRQOL in the general Japanese middle-aged population. Methods Data were obtained from 1211 male and female respondents (39.4 ± 10.9 year, mean ± SD from an Internet-based survey of registrants of an Internet research service. Physical activity level was estimated from the short form of the International Physical Activity Questionnaire. HRQOL was assessed with the Medical Outcomes Survey Short Form-8 questionnaire (SF-8. Based on the current national guidelines for exercise in Japan, respondents were divided into a recommended group, an insufficient group, and an inactive group according to their estimated weekly physical activity level. Multivariate analyses of covariance were utilized. Results Across both genders, the recommended group had significantly higher physical functioning (PF scores than the inactive group (p Conclusion Individuals who attained the recommended level of physical activity had better scores on some dimensions of HRQOL than those who did not, suggesting that the recommended level of physical activity may be applicable not only to the physiological objective outcomes but also to some dimensions in both the physical and mental aspects of HRQOL.

    Full Text Available Abstract Background Evidence suggests possible synergetic effects of multiple lifestyle behaviors on health risks like obesity and other health outcomes. Therefore it is important to investigate associations between dietary and physical activity behavior, the two most important lifestyle behaviors influencing our energy balance and body composition. The objective of the present study is to describe the relationship between energy, nutrient and food intake and the physical activity level among a large group of European adolescents. Methods The study comprised a total of 2176 adolescents (46.2% male from ten European cities participating in the HELENA (Healthy Lifestyle in Europe by Nutrition in Adolescence study. Dietary intake and physical activity were assessed using validated 24-h dietary recalls and self-reported questionnaires respectively. Analyses of covariance (ANCOVA were used to compare the energy and nutrient intake and the food consumption between groups of adolescents with different physical activity levels (1st to 3rd tertile. Results In both sexes no differences were found in energy intake between the levels of physical activity. The most active males showed a higher intake of polysaccharides, protein, water and vitamin C and a lower intake of saccharides compared to less active males. Females with the highest physical activity level consumed more polysaccharides compared to their least active peers. Male and female adolescents with the highest physical activity levels, consumed more fruit and milk products and less cheese compared to the least active adolescents. The most active males showed higher intakes of vegetables and meat, fish, eggs, meat substitutes and vegetarian products compared to the least active ones. The least active males reported the highest consumption of grain products and potatoes. Within the female group, significantly lower intakes of bread and cereal products and spreads were found for those reporting to

    The aim of the study was to examine the relationship between employment status and job activity level with physical activity (PA) and sedentary time, stratified by gender and country. Cross-sectional study design. Data from working age adults (18-65 years) from two cross-sectional studies, the Swedish 2001-2002 and 2007-2008 Attitude Behavior and Change Study (ABC; n=1165) and the 2003-2006 US National Health and Nutrition Examination Survey (NHANES; n=4201), were stratified by employment status (employed and not employed) and job activity level (active, sedentary and mixed). PA in counts×min(-1) and time spent in sedentary, low and moderate or higher intensity were measured with accelerometers. Analyses were conducted in 2012-2013. In NHANES, the employed had significantly higher counts×min(-1) and spent more time in moderate or higher intensity PA than those not employed. In ABC, no significant differences were observed between employed and unemployed. Adults with active versus sedentary occupations had higher counts×min(-1) and less sedentary time in both the USA and Sweden and in both men and women. For example, counts×min(-1) were 20-40% greater in active versus sedentary jobs. Employment status is related to PA and sedentary time among men and women in the USA but not in Sweden. Among the employed, occupational PA is associated with total PA and sedentary time for both genders and in both countries. Comparisons of PA levels based on objective measurements can refine understanding of country differences in activity. Copyright © 2015 Sports Medicine Australia. All rights reserved.

    The 3 study objectives were to compare the activity levels of older people who had received a restorative home care service with those of people who had received "usual" home care, explore the predictors of physical activity in these 2 groups, and determine whether either group met the minimum recommended activity levels for their age group. A questionnaire was posted to 1,490 clients who had been referred for a home care service between 2006 and 2009. Older people who had received a restorative care service were more active than those who had received usual care (p = .049), but service group did not predict activity levels when other variables were adjusted for in a multiple regression. Younger individuals who were in better physical condition, with good mobility and no diagnosis of depression, were more likely to be active. Investigation of alternatives to the current exercise component of the restorative program is needed.

    Physical activity could benefit drug users' physiological and mental health. Previous research has suggested that physical activity levels change when drug users enter prison. Twenty-five class A drug users who were new to prison answered physical activity and drug use cross-sectional questionnaires, took a submaximal fitness test and wore a pedometer for 1 week. Participants' mean aerobic capacity was estimated as 49 mls O2/kg/min (±12 SD). Their mean self-reported walking distance outside of prison was 4.67 miles on an average day (±4.14 SD). Pedometer data suggest they walked a mean of 1.8 miles/day in prison. Many class A drug users entering prison had high levels of fitness and physical activity before admission, often gained from walking. Walking activity reduced when they entered prison, posing a challenge to maintaining healthy activity levels.

    To investigate if trapezius muscle activity increases over time during visually demanding near work. The vision task consisted of sustained focusing on a contrast-varying black and white Gabor grating. Sixty-six participants with a median age of 38 (range 19-47) fixated the grating from a distance of 65 cm (1.5 D) during four counterbalanced 7-min periods: binocularly through -3.5 D lenses, and monocularly through -3.5 D, 0 D and +3.5 D. Accommodation, heart rate variability and trapezius muscle activity were recorded in parallel. General estimating equation analyses showed that trapezius muscle activity increased significantly over time in all four lens conditions. A concurrent effect of accommodation response on trapezius muscle activity was observed with the minus lenses irrespective of whether incongruence between accommodation and convergence was present or not. Trapezius muscle activity increased significantly over time during the near work task. The increase in muscle activity over time may be caused by an increased need of mental effort and visual attention to maintain performance during the visual tasks to counteract mental fatigue.

    Identifying factors that improve job satisfaction of new doctors and ease the difficult transition from student to doctor is of great interest to public health agencies. Studies to date have focused primarily on the value of changes to medical school curricula and induction processes in this regard, but have overlooked the extent to which institutional support can influence new doctors' enjoyment of and attitude to work. Here, we examine variation in the perceived level of support received by new medical graduates in the United Kingdom (UK) from their employer and whether this influences enjoyment of and attitudes to the first postgraduate year, and whether doctors who perceived a lower level of support were less inclined to intend a long term career in medicine in the UK. All UK medical graduates of 2012 were surveyed in 2013 in a cross-sectional study, towards the end of their first post-graduate year (the 'F1' year of the 2-year Foundation Training Programme for new UK doctors). We used linear regression to assess whether the level of support doctors reported receiving from their employing Trust (Very Good, Good, Adequate, Poor, or Very Poor) was associated with the extent to which they enjoyed their F1 year. Similarly, we assessed the strength of associations between self-reported level of Trust support and doctors' responses to 12 statements about fundamental aspects of their working lives, each assessed on a 5-point scale of agreement. Using χ (2) tests we examined whether doctors' intentions to practise medicine in the UK varied with the level of support they reported receiving from their Trust. The response rate was 45 % (2324/5171). Of 2324 responding junior doctors, 63.8 % reported receiving 'Very Good' (23.6 %) or 'Good' (40.2 %) initial support from their Trust, while a further 27.4 % stated they received 'Adequate' support. 'Poor' support was reported by 5.8 % and 'Very Poor' support by 2.2 %. We found very strong positive associations between

    This study examined age and gender differences in physical activity levels and various physical activity patterns of 11-14-year-old Turkish adolescents and also determined if these differ between genders. Six hundred and fifty girls and 666 boys between the ages of 11 and 14 years constituted the sample of this study. Participants self-reported physical activity levels and patterns were determined by a Weekly Activity Checklist. A 2 x 4 (Gender x Age) MANOVA revealed overall significant main effect of gender and age on the physical activity level of adolescents; however, gender x age interaction effect was not significant. The findings indicated an interaction effect was not significant. The findings indicated an age-related decline in physical activity level, an increase in participation in low activities, and a decrease in participation in moderate and vigorous activities in 11-14-year-old Turkish adolescents. In addition it was found that boys were more active than girls and participated more in moderate and vigorous activities.

    2014-09-01

    The purpose of this study was to examine whether white blood cell (WBC) level mediated the relationship between physical activity and prostate-specific antigen (PSA) levels. Data from the 2003-2006 National Health and Nutrition Examination Survey were used; 1,726 U.S. adult men (aged 40 years or older) provided complete data on the study variables. Participants wore an ActiGraph 7164 accelerometer for a 7-day period to measure their physical activity behavior, and PSA and WBC levels were obtained from a blood sample. After adjustments, results showed that moderate-to-vigorous physical activity (MVPA) was inversely associated with WBC count (b = - .03; 95% CI [ - 0.04, - 0.006; p = .01), and WBC count (b = .10; 95% CI [0.009, 0.18; p = .04) was positively associated with PSA. Both the Sobel (coef. = - .004, SE = .002; z = - 2.0; p = .03) and the Aroian (coef. = - .004, SE = .002; z = - 1.9; p = .03) tests demonstrated that WBC mediated the relationship between physical activity and PSA. Additionally, among 107 participants with prostate cancer, survivors engaging in more MVPA had lower levels of WBC (b = - .04; 95% CI [ - 0.09, - 0.0009; p = .04). Conclusion Physical activity may influence PSA levels through WBC modulation; however, future research is needed to determine the direction of causality. Additionally, prostate cancer survivors engaging in higher levels of MVPA had lower levels of WBC, underscoring the importance of promoting physical activity among prostate cancer survivors.

    Long-term potentiation (LTP) is widely accepted as the best studied model for neurophysiological mechanisms that could underlie learning and memory formation. Despite a number of studies indicating that β-adrenoceptors in the hippocampal dentate gyrus (DG) is involved in the modulation of learning and memory as well as LTP, few studies have used glutamate release as a visual indicator in awake animals to explore the role of β-adrenoceptors in learning-dependent LTP. Therefore, in the present study, the effects of propranolol (an antagonist of β-adrenoceptor) and isoproterenol (an agonist of β-adrenoceptor) on extracellular concentrations of glutamate and amplitudes of field excitatory postsynaptic potential were measured in the DG region during active avoidance learning in freely moving conscious rats. In the control group, the glutamate level in the DG was significantly increased during the acquisition of active avoidance behavior and returned to basal level following extinction training. In propranolol group, antagonism of β-adrenoceptors in the DG significantly reduced the change in glutamate level, and the acquisition of the active avoidance behavior was significantly inhibited. In contrast, the change in glutamate level was significantly enhanced by isoproterenol, and the acquisition of the active avoidance behavior was significantly accelerated. Furthermore, in all groups, the changes in glutamate level were accompanied by corresponding changes in field excitatory postsynaptic potential amplitude and active avoidance behavior. Our results suggest that activation of β-adrenoceptors in the hippocampal DG facilitates active avoidance learning by modulations of glutamate level and synaptic efficiency in rats.

    To investigate the link between serum vaspin levels and physical activity and/or physical fitness in Japanese. A total of 156 subjects (81 men and 75 women) was enrolled in this cross-sectional study. Serum vaspin levels, physical activity by uniaxial accelerometers, peak oxygen uptake, and metabolic risk parameters were evaluated. We also assessed anthropometric and body composition parameters. Serum vaspin levels were over the level of 10 ng/mL in 15 subjects (9.6 %: Vaspin High group). In Vaspin Low group (men and 67 women), serum vaspin levels were 0.12 ± 0.18 ng/mL in men and 0.39 ± 0.70 ng/mL in women. Peak oxygen uptake was significantly and positively correlated with serum vaspin levels even after adjusting for age, physical activity evaluated by Σ[metabolic equivalents × h per week (METs[Symbol: see text]h/w)], BMI, and other confounding factors in men. In turn, physical activity was significantly and positively correlated with serum vaspin levels even after adjusting for confounding factors in women. Serum vaspin levels were closely associated with physical fitness in men and physical activity in women independent of body composition in this Japanese cohort.

    Kerala is a state in India with a high prevalence of cardiovascular diseases and diabetes. In order to control these diseases, the prevalence of modifiable risk factors such as low physical activity need to be studied. For this a cross-sectional study was conducted to assess the level of physical activity among 240 residents aged between 15 and 65 years in Kulappuram, a village in north Kerala. Low level of physical activity was seen in 65.8% of the study participants. The average duration of moderate to vigorous intensity physical activity per day in different domains such as work, travel, and recreation were 40.5, 10.1, and 12.7 minutes, respectively. The average duration of sedentary activities was 284.3 minutes per day. The level of physical activity was more among those engaged in unskilled work (adjusted odds ratio = 4.32; confidence interval = 1.38-13.51) and unmarried persons (adjusted odds ratio = 3.65; confidence interval = 1.25-10.65). No statistically significant difference in physical activity level was seen in different age, education, religious, and economic categories. The study concludes that the physical activity level was low in the study population. © 2015 APJPH.

    Full Text Available Nello scenario attuale la gran parte delle città è impegnata in investimenti nel settore turistico al fine di rendersi maggiormente competitive e di attrarre investimenti. Questo rinnovato interesse verso il settore turistico e del tempo libero ha generato una nuova tipologia turistica riconosciuta come turismo urbano, sviluppatosi sostanzialmente durante tutti gli anni Novanta. Partendo dalla consapevolezza che lo spostamento sia una condizione necessaria allo svolgimento della pratica turistica tout court e di quella urbana in particolare, l’articolo tenta di mettere in evidenza la capacità di adattamento dell’offerta di trasporto urbano alle esigenze turistiche. La relazione tra sistema di trasporto urbano e pratica turistica, se esiste, può essere analizzata alla luce dei principali interventi messi in campo per adattare l’offerta di trasporto alle richieste di un’utenza temporanea ma con una forte incidenza sul bilancio economico della città.This paper deals with leisure mobility that is a special form of mobility enabled by tourists in urban areas. As a matter of fact, tourism activity occupies a central role in the economies of cities today. Most of the processes of urban renewal actually still in progress always provide investment in tourism and leisure. The metropolitan areas as well as small and medium-sized cities, to redefine its development model stake on the rejuvenation of the tourism and culture in order to attract visitors and tourists. In this context, the urban supply system for tourism-oriented services has been enhanced with new ways of enjoying the city. Transport supply to enable travel within the city plays a significant role. Sometimes the mean of transport turns into a tourist attraction itself both giving value to tourist experience and improving accessibility to urban attractions. The first part of this paper refers to theoretical aspect of the tourism phenomenon. This is to underline how tourism is a

    Practicing activities improves recovery after stroke, but many people in hospital do little activity. Feedback on activity using an accelerometer is a potential method to increase activity in hospital inpatients. This study's goal is to investigate the effect of feedback, enabled by a Smart watch, on daily physical activity levels during inpatient stroke rehabilitation and the short-term effects on simple functional activities, primarily mobility. A randomized controlled trial will be undertaken within the stroke rehabilitation wards of the Second Affiliated hospital of Anhui University of Traditional Chinese Medicine, Hefei, China. The study participants will be stroke survivors who meet inclusion criteria for the study, primarily: able to participate, no more than 4 months after stroke and walking independently before stroke. Participants will all receive standard local rehabilitation and will be randomly assigned either to receive regular feedback about activity levels, relative to a daily goal tailored by the smart watch over five time periods throughout a working day, or to no feedback, but still wearing the Smart watch. The intervention will last up to 3 weeks, ending sooner if discharged. The data to be collected in all participants include measures of daily activity (Smart watch measure); mobility (Rivermead Mobility Index and 10-metre walking time); independence in personal care (Barthel Activities of Daily Living (ADL) Index); overall activities (the World Health Organization (WHO) Disability Assessment Scale, 12-item version); and quality of life (the Euro-Qol 5L5D). Data will be collected by assessors blinded to allocation of the intervention at baseline, 3 weeks or at discharge (whichever is the sooner); and a reduced data set will be collected at 12 weeks by telephone interview. The primary outcome will be change in daily accelerometer activity scores. Secondary outcomes are compliance and adherence to wearing the watch, and changes in mobility

    Worldwide studies show inequalities in physical activity levels related to socio-demographic characteristics. In Colombia, among the countries in Latin America with the highest inequality, the evidence related to inequalities in physical activity is limited. It is imperative to identify disparities in physical activity in the country, to guide the design of public policies aimed at promoting physical activity. 1) To estimate the prevalence and associated factors of meeting physical activity recommendations; 2) to assess inequalities by gender and socioeconomic status in meeting physical activity recommendations, and 3) to assess the trends in physical activity prevalence within a five-year period. A secondary analysis of data from the 2010 National Nutrition Survey was conducted. The sample included 27,243 adults. The International Physical Activity Questionnaire was used to measure leisure time and transport domains. Socioeconomic status was measured by the Sisben level. Compared to men, women were less likely to meet physical activity recommendations in all domains. Compared to adults from high socioeconomic-status households, low socioeconomic-status adults had a lower prevalence of meeting physical activity recommendations during leisure time and the highest prevalence of using a bicycle for transport. The factors associated with meeting physical activity recommendations differed by gender and physical activity domain. Household and individual variables explained 13.6% of the inequalities observed by gender, and 23.2% of the inequalities by socioeconomic status. In a five-year period, the prevalence of physical activity in leisure time decreased, while the physical activity of walking for transport increased and biking for transport did not change. Future interventions to increase physical activity levels in Colombia must consider inequalities by gender and socioeconomic status. Of special concern is the low prevalence of meeting physical activity

    As a sedentary lifestyle leads to numerous health problems, it is important to keep constant motivation for a more active lifestyle. A large majority of the worldwide population, such as office workers, long journey vehicle drivers and wheelchair users, spends several hours every day in sedentary activities. The postures that sedentary lifestyle users assume during daily activities hide valuable information that can reveal their wellness and general health condition. Aiming at mining such underlying information, we developed a cushion-based system to assess their activity levels and recognize the activity from the information hidden in sitting postures. By placing the smart cushion on the chair, we can monitor users' postures and body swings, using the sensors deployed in the cushion. Specifically, we construct a body posture analysis model to recognize sitting behaviors. In addition, we provided a smart cushion that effectively combine pressure and inertial sensors. Finally, we propose a method to assess the activity levels based on the evaluation of the activity assessment index (AAI) in time sliding windows. Activity level assessment can be used to provide statistical results in a defined period and deliver recommendation exercise to the users. For practical implications and actual significance of results, we selected wheelchair users among the participants to our experiments. Features in terms of standard deviation and approximate entropy were compared to recognize the activities and activity levels. The results showed that, using the novel designed smart cushion and the standard deviation features, we are able to achieve an accuracy of (>89%) for activity recognition and (>98%) for activity level recognition.

    The main goals of this cross-sectional survey were (a) to describe the associations between sex, age, and physical activity behavior and (b) to describe the age and sex-related associations with the choice of structured (formal) and unstructured (nonformal) physical activity programs. At baseline, data were selected randomly from 1,013 students, from the 7th to the 12th grades. A response rate of 73% (n = 739) was obtained. Accordingly, the sample of this study consisted of 594 adolescents (304 females and 290 males) with mean age of 15.9 years (range 13-20). Physical activity was assessed by means of a questionnaire. A questionnaire about leisure activities was applied to the sample to define the nominal variable "nature of physical activity." The data showed that significantly more girls than boys (p < or = .001) belonged to the sedentary group (80.7% girls) and low activity group (64.5% girls). Boys more frequently belonged to the more active groups (92.1%; p < or = .001). The older participants were more engaged in formal physical activities, whereas the younger mostly chose informal ones whatever their level of physical activity. There were more significant differences in girls' physical activity groups (chi 2 = 20.663, p < or = .001) than in boys' (chi 2 = 7.662, p < or = .05). Furthermore, active girls chose more structured physical activities than their sedentary counterparts (18.8% vs. 83.3%). However, boys preferred unstructured activities regardless of physical activity group (83.7% vs. 58.5%; p < or = .05). It can be concluded that as age increased, organized sports activities became a relatively more important component of total weekly activity for both male and female participants.

    The aim of this study is to investigate the effects of different home cooking techniques (boiling, steaming, and stir-frying) in kale and red cabbage, on the levels of bioactive compounds (carotenoids, anthocyanins and phenolic compounds) determined by high-performance liquid chromatography coupled with photodiode array and mass spectrometry detectors (HPLC-DAD-MS(n)), and on the antioxidant activity evaluated by ABTS, ORAC and cellular antioxidant activity (CAA) assays. The steaming technique resulted in a significant increase in phenolic content in kale (86.1%; pkale, steaming resulted in significant increases in antioxidant activity levels in all of the evaluation methods. In the red cabbage, boiling resulted in a significant increase in antioxidant activity using the ABTS assay but resulted in a significant decrease using the ORAC assay. According to the CAA assay, the stir-fried sample displayed the highest levels of antioxidant activity. Copyright © 2015 Elsevier Ltd. All rights reserved.

    Young people are more likely to have experimented with e-cigarettes (e-cigs) compared with older adults. Few studies identify reasons for experimentation/use of e-cigs among young people; we sought to discover what drives college students to use e-cigs. Undergraduate students (ages 18-23) at four universities in New York State were surveyed. Among e-cig ever users (n=429), reasons for use were examined. A multinomial logistic regression model analyzed the relative risk of reasons for using e-cigs among discontinued, current non-daily and current daily e-cig users. Using e-cigs for enjoyment was associated with current non-daily (RR=2.11, 95% CI=1.18-3.75) and current daily use (RR=19.1, 95% CI=3.71-98.54). Non-daily use was related to use because e-cigs are less toxic than cigarettes (RR=2.80, 95% CI=1.75-4.50). More daily users reported use to quit smoking compared with either non-daily or discontinued users (53.3% vs. 12.2% and 13.3%, respectively; preason. The exception was daily e-cig users, who often reported use for quitting/reduction of smoking. Rather, college students report usage reasons related to affect (e.g. enjoyment). Overall, enjoyment was reported more often than was use for quitting smoking; affective reasons likely play a role in the popularity of e-cigs and should be considered in future assessments of e-cig users.

    Full Text Available This article examines individual and social influences on investments in health and enjoyment from immediate consumption. Our lab experiment mimics the problem of health investment over a lifetime (Grossman 1972a, 1972b. Incentives to find the appropriate expenditures on life enjoyment and health are given by making in each period come period a function of previous health investments. In order to model social effects in the experiment, we randomly assigned individuals to chat/observation groups. Groups were permitted to freely chat between repeated lifetimes. Two treatments were employed: In the Independent-rewards treatment, an individual’s rewards from investments in life enjoyment depend only on his choice and in the Interdependent-rewards treatment; rewards not only depend on an individual’s choices but also on their similarity to the choices of the others in their group, generating a premium on conformity. The principal hypothesis is that gains from conformity increase variance in health behavior among groups and can lead to suboptimal performance. We tested three predictions and each was supported by the data: the Interdependent-rewards treatment 1 decreased within-group variance, 2 increased between-group variance, and 3 increased the likelihood of behavior far from the optimum with respect to the dynamic problem. We also test and find support for a series of subsidiary hypotheses. We found: 4 Subjects engaged in helpful chat in both treatments; 5 there was significant heterogeneity among both subjects and groups in chat frequencies; and 6 chat was most common early in the experiment, and 7 the interdependent rewards treatment increased strategic chat frequency. Incentives for conformity appear to promote prosocial behavior, but also increase variance among groups, leading to convergence on suboptimal strategies for some groups. We discuss these results in light of the growing literature focusing on social networks and health outcomes.

    Full Text Available The realization and enjoyment of socio-economic rights is crucial to overcoming the challenges of abject poverty. These rights offer those living in poverty access to the basic and essential things that are necessary to live a dignified life. However, it is generally agreed that the protection and enjoyment of socio-economic rights is accorded less importance amongst the comity of civilized nations. Majority of governments give priority to the protection of civil and political rights to the detriment of socio-economic rights. Despite the United Nations stance on the non-hierarchical structure within human rights classifications, there is general ambivalence towards the violation of socio-economic rights by those entrusted to protect them. Though many international and regional treaties protect socio-economic rights, which instruments have been domesticated by countries; the picture appears gloomy in terms of effective realisation and protection of socio-economic rights. Their enforcements still remain a challenge for this millennium. The impediments to the realization of these rights are the focus of this paper. Through a detailed analysis of international, regional and domestic legislative framework and jurisprudence, this study provides a systematic exposition of the obstacles that impact on the ability of states to fulfil their socio-economic rights obligations under the various and diverse instruments. The impediments that are discussed in this paper include: a proliferations of human rights; corruption and inept leadership in Africa; inadequate enforcement mechanism; poor and ineffective state reports; international sanctions; wars and conflicts; globalization; debt repayment by developing countries; difficulties of monitoring compliance by State Parties and conflict of laws. In conclusion, the paper proffers a panacea and alternative models for the realization and enjoyments of socio-economic rights.

    2008-10-01

    This study examined three assumptions of the theory of deliberate practice for practice playing music on an electronic keyboard. 40 undergraduate students, divided into two separate groups, practiced one of two music sequences and rated the relevance of practice for improving performance on the sequences, the amount of effort needed to learn the sequences, and the inherent enjoyment of practice sessions. Findings for each assumption were consistent with those suggested by theory but also showed that perceptions are affected by the amount of practice completed and performance of the skill.

    Low-energy ion beam bombardment has been used to mutate a wide variety of plant species. To explore the indirect effects of low-energy ion beam on biological damage due to the free radical production in plant cells, the increase in antioxidant enzyme activities and lipid peroxidation level was investigated in ion-bombarded rice seeds. Local rice seeds were bombarded with nitrogen or argon ion beams at energies of 29-60 keV and ion fluences of 1 × 1016 ions cm-2. The activities of the antioxidant enzymes; superoxide dismutase (SOD), catalase (CAT), ascorbate peroxidase (APX), dehydroascorbate reductase (DHAR), glutathione reductase (GR), glutathione S-transferase (GST) and lipid peroxidation level were assayed in the germinated rice seeds after ion bombardment. The results showed most of the enzyme activities and lipid peroxidation levels in both the argon and nitrogen bombarded samples were higher than those in the natural control. N-ion bombardment could induce higher levels of antioxidant enzyme activities in the rice samples than the Ar-ion bombardment. Additional effects due to the vacuum condition were found to affect activities of some antioxidant enzymes and lipid peroxidation level. This study demonstrates that ion beam bombardment and vacuum condition could induce the antioxidant enzyme activity and lipid peroxidation level which might be due to free radical production in the bombarded rice seeds.

  14. Resource Leveling Based on Backward Controlling Activity in Line of Balance

    2017-01-01

    Full Text Available The line of balance method that provides continuous and uninterrupted use of resources is one of the best methods for repetitive project resource management. This paper develops a resource leveling algorithm based on the backward controlling activity in line of balance. The backward controlling activity is a kind of special activity, and if its duration is prolonged the project duration could be reduced. It brings two advantages to the resource leveling: both the resource allocated on the backward activity and the project duration are reduced. A resource leveling algorithm is presented which permits the number of crews of the backward controlling activity to be reduced until the terminal situation is reached, where the backward controlling activity does not exist or the number of crews cannot be reduced. That adjustment enables the productivity of all activities to be consistent. An illustrative pipeline project demonstrates the improvement in resource leveling. And this study designed a MATLAB program to execute the design algorithm. The proposed model could help practitioners to achieve the goals of both resource leveling and project duration reduction without increasing any resource.

    There is mounting evidence demonstrating the importance of adequate physical activity to promote better well-being among hemodialysis patients. Available data pertaining to the levels of physical activity and its determinants among hemodialysis patients is, however, scarce in Malaysia. The objectives of this study are hence to determine the levels of physical activity and it associated factors among hemodialysis patients. A total of 70 subjects were recruited from three dialysis centres in Selangor. A face-to-face interview was conducted to obtain socio-demographic data and subjects' knowledge on dietary sources. Medical history, biochemical parameters and weight status were obtained from medical records. Physical activity level (PAL) was assessed using the Global Physical Activity Questionnaire (GPAQ). A total of 81.4% and 18.6% of the respondents had low and moderate PALs, respectively. Thus, none of the respondents had high PAL. Serum creatinine, education level, personal income and knowledge score on potassium-related medical complications were factors found to correlate significantly with PAL. Multiple linear regression analysis showed that higher PAL was predicted by a lower knowledge score on dietary sodium source, higher education and higher serum creatinine. Despite consistent documentation of the potential positive impact of physical exercise on hemodialysis outcomes, the level of physical activity remains low among these patients. It is hoped that these findings can add to the existing body of knowledge and serve as a supporting document for the formulation of appropriate interventions to improve the status of physical activity among hemodialysis patients in Malaysia.

    During follow-up of acromegaly patients, there is a discordance rate of 30% between the measurements of growth hormone and insulin-like growth factor-1 levels. Further tests are required to determine disease activity in patients with discordant results. This study was planned to investigate an association of serum levels of matrix metalloproteinase-2, matrix metalloproteinase-9, and cathepsin B with disease activity in acromegaly patients. In this study, 64 acromegaly patients followed in our clinic were divided into two groups according to the 2010 consensus criteria for cure of acromegaly as patients with active disease (n = 24) and patients with controlled disease (n = 40). Serum matrix metalloproteinase-2, matrix metalloproteinase-9, and cathepsin B levels were measured by the enzyme-linked immunosorbent assay method. The mean serum matrix metalloproteinase-2 level was significantly higher in the active acromegaly patients than in the controlled acromegaly patients (150.1 ± 54.5 ng/mL vs. 100.2 ± 44.6 ng/mL; p matrix metalloproteinase-9 and cathepsin B levels (p = 0.205 and p = 0.598, respectively). Serum matrix metalloproteinase-2 levels of 118.3 ng/mL and higher had a sensitivity of 75% and a specificity of 77.5% in determining active disease. The risk of active acromegaly was 3.3 fold higher in the patients with a matrix metalloproteinase-2 level of >118.3 ng/mL than in the patients with a matrix metalloproteinase-2 level of matrix metalloproteinase-2 level is increased in the active acromegaly patients and a threshold value in determining active disease was defined for serum matrix metalloproteinase-2 level. This study is the first to compare acromegaly patients having active or controlled disease in terms of matrix metalloproteinase-2 and matrix metalloproteinase-9 levels. The results need to be confirmed by a study that will be conducted in a larger patient group also including a healthy control group to demonstrate the

    Lumbar decompression surgery (LDS) and total hip arthroplasty (THA) are frequently performed in the elderly population, but very little is known about their subsequent physical capacity and participation in leisure activities. Despite similar demographics and comorbidities, it is questionable whether LDS patients achieve equally high levels of physical capacity and quality of life postoperatively as do THA patients. The aim was to compare the physical activity level, participation in leisure activities and related quality of life 1 year after an LDS and THA procedure. Data from 95 THA patients and 83 LDS patients were gathered from questionnaires on self-reported physical activity level, leisure activities and quality of life. LDS and THA patients reported equally moderate levels of physical activity. The median score was 42.3 METs/day (IQR 37.9; 47.7) for the LDS group and 41.0 METs/day (IQR 38.5; 48.5) for the THA group (p = 0.79). Weekly time consumption for leisure activities in the LDS group was a median of 420 min/week (IQR 210; 660) compared to a median of 480 min/week (IQR 240; 870) in the THA group (p = 0.16). Regarding quality of life, LDS patients reported significantly worse Euroqol Five Dimensions scores with a median value of 0.740 (IQR 0.68; 0.82) compared to THA patients' median of 0.824 (IQR 0.72; 1.0), p leisure activities, LDS patients did not achieve a quality of life comparable to that of THA patients 1 year postoperatively.

    2014-11-01

    This research investigates the influence that gender, single-sex and co-educational schooling can have on students' mathematics education in second-level Irish classrooms. Although gender differences in mathematics education have been the subject of research for many years, recent results from PISA (Programme for International Student Assessment) show that there are still marked differences between the achievement and attitude of male and female students in Irish mathematics classrooms. This paper examines the influence of gender in more detail and also investigates the impact of single-sex or co-educational schooling. This is a follow on study which further analyses data collected by the authors when they designed a pedagogical framework and used this to develop, implement and evaluate a teaching intervention in four second-level Irish schools. The aim of this pedagogical framework was to promote student interest in the topic of algebra through effective teaching of the domain. This paper further analyses the quantitative data collected and investigates whether there were differences in students' enjoyment and achievement scores based on their gender and whether they attended single-sex or co-educational schools.

    Full Text Available The influence of the physical activity environment in the home and at work on cardiorespiratory fitness (CRF and objectively-measured physical activity has not been extensively studied. We recruited 147 women with a (mean ± SD age of 54 ± 7 years and without evidence of chronic disease. The physical activity environment was assessed by self-report (Assessing Levels of PHysical Activity or ALPHA questionnaire, CRF using a submaximal step test, usual physical activity using combined heart rate and accelerometry, as well as by a validated questionnaire (Recent Physical Activity Questionnaire. Summary scores of the home environment and the work environment derived from the ALPHA questionnaire were positively correlated with CRF after adjustment for age (r = 0.18, p = 0.03 and r = 0.28, p < 0.01, respectively. Women owning a bicycle or having a garden (which may prompt physical activity had higher CRF; those with a bicycle at home also had a higher physical activity energy expenditure. Similarly, women who had access to fitness equipment at work had higher CRF. In conclusion, these results provide new insights into potential environmental influences on physical capacity and physical activity that could inform the design of physical activity promotion strategies.

    Background Functional dependence and the risks of disability increase with age. The loss of independence is thought to be partially due to a decrease in physical activity. However, in populations, accurate measurement of physical activity is challenging and may not provide information on functional impairment. Methods This study therefore assessed physical functionality and physical activity level in a group of nonagenarians (11 men/11 women; 93 ± 1 years, 66.6 ± 2.4 kg, body mass index [BMI] = 24 ± 1 kg/m2) and a group of participants aged 60–74 years (17 men/15 women; 70 ± 1 years, 83.3 ± 3.0 kg, BMI = 29 ± 1 kg/m2) from the Louisiana Healthy Aging Study. Physical activity level was calculated from total energy expenditure (TEE) and resting metabolic rate (RMR). Physical functionality was assessed using the Reduced Continuous Scale Physical Functional Performance Test (CS-PFP10). Results Nonagenarians had lower absolute ( p < .001) and adjusted ( p < .007) TEE compared to participants aged 60–74 years which was attributed to a reduction in both RMR and physical activity level. Nonagenarians also had reduced functional performance ( p < .001) which was correlated with activity level (r = 0.68, p < .001). Conclusions When compared to individuals aged 60–74 years, 73% of the reduction in TEE in nonagenarians can be attributed to a reduction in physical activity level, the remaining being accounted for by a reduction in RMR. The reduced physical activity in nonagenarians is associated with less physical functionality. This study provides the first objective comparison of physical functionality and actual levels of physical activity in older individuals. PMID:17634327

    Acute aerobic exercise improves mood and activates the endocannabinoid (eCB) system in physically active individuals; however, both mood and eCB responses to exercise may vary based on habitual levels of physical activity. This study aimed to examine eCB and mood responses to prescribed and preferred exercises among individuals with low, moderate, and high levels of physical activity. Thirty-six healthy adults (21 ± 4 yr) were recruited from low (≤60 min moderate-vigorous physical activity [MVPA] per week), moderate (150-299 min MVPA per week), and high (≥300 MVPA per week) physical activity groups. Participants performed both prescribed (approximately 70%-75% max) and preferred (i.e., self-selected) aerobic exercise on separate days. Mood states and eCB concentrations were assessed before and after exercise conditions. Both preferred and prescribed exercise resulted in significant increases (P exercise elicited positive mood improvements compared with preexercise values, but changes in state anxiety, total mood disturbance, and confusion were greater in the preferred condition (P mood disturbance in the preferred condition (P mood or eCB outcomes. These results indicate that eCB and mood responses to exercise do not differ significantly between samples with varying physical activity levels. This study also demonstrates that in addition to prescribed exercise, preferred exercise activates the eCB system, and this activation may contribute to positive mood outcomes with exercise.

    We theorize and test the health of older adults as a result of their activity engagement, as well as a product of their spouse's engagement. We draw on 15 waves of couple-level data from the Household, Income and Labour Dynamics in Australia (HILDA) Survey. Using responses of time engaged in nine different activities, we estimate Latent Class Models to describe activity profiles of partnered older adults. Given potential health selections into activity engagement, we lag older adults' activity engagement by one wave to examine its association with subsequent health. We then investigate associations between the lag of the spouse's activities with respondents' health, controlling for their own activity engagement at the previous wave. We find four activity profiles for men, and three for women. Respondents who were predominantly engaged in community activities generally report better subsequent health. Beyond their own activity engagement, for both older men and women, having a partner who was also community engaged associate with better subsequent health, though for older women, there were little differences between having a husband who was community engaged or inactive. Our findings highlight the value of considering activities of partnered older adults at the couple level. Copyright © 2018 Elsevier Ltd. All rights reserved.

    Objective Medication-overuse headache is often comorbid with emotional disturbances and disordered personality traits. The aim of the present study was to determine whether depression and insomnia complaints were associated with satisfaction and enjoyment with one's own life in medication-overuse headache patients, and whether insomnia complaints were able to explain part of the variance of Quality of Life explained by depression. Methods Participants were 187 consecutive adult outpatients admitted to the Regional Referral Headache Centre of the Sant'Andrea Hospital in Rome, Italy. Patients were administered the Quality of Life Enjoyment and Satisfaction Questionnaire, the Beck Depression Inventory - II, and the Athens Insomnia Scale. Results The Beck Depression Inventory was associated with all the dimensions of the Quality of Life Enjoyment and Satisfaction Questionnaire, with more severe depression being associated independently with lower satisfaction and enjoyment with one's own life. The Athens Insomnia Scale was independently and significantly associated only with physical health, such that patients with more insomnia complaints were 3.1 times ( p satisfaction. Conclusions Our findings confirmed that medication-overuse headache patients has a negative impact on quality of life and suggested that depression and insomnia were independently associated with satisfaction and enjoyment of life in medication-overuse headache patients. The early recognition and appropriate treatment of comorbid psychopathological symptoms are crucial to improve satisfaction and enjoyment of life in medication-overuse headache patients.

    to investigate the association between objective measures of physical activity levels, physical fitness and screen time in Colombia children and adolescents from Bogota, Colombia. a sample of 149 healthy Colombian youth, children and adolescents (9-17.9 years old) participated in the study. Physical activity level was assessed over 7 days using an accelerometer. Weight, height, waist circumference, hip waist, subscapular/ triceps skinfold thicknesses and self-reported screen time (television/internet and videogame-viewing time) were measured. Aerobic capacity, handgrip strength, standing broad jump, vertical jump, speed/agility and flexibility were used as indicators of physical fitness. in girls with a high level of physical activity had favorable aerobic capacity (r = 0.366) and inverse relationship with subscapular/triceps skinfold thicknesses (r = -0.257) and (r = -0,237) p < 0.05, respectively. In boys, vigorous physical activity were associated with higher values of flexibility (r = 0.277) and aerobic capacity (r = 0.347), p < 0.05. Finally, the participants who watched 2 h or less of television per day showed 1.81 times (95%CI 1.401 to 2.672) that met physical activity guidelines. the healthy Colombian youth who reported moderate to vigorous objective measures of physical activity levels, presented higher levels in physical fitness especially in aerobic capacity and flexibility and lower values in subscapular/triceps skinfold thicknesses.

    We analyzed muscular activity of the lower extremities during level walking using positron emission tomography (PET) with 18 F-fluorodeoxyglucose ( 18 F-FDG). We examined 17 healthy male subjects; 11 were assigned to a walking group and 6 to a resting group. After 18 F-FDG injection, the walking group subjects walked at a free speed for 15 min. A whole-body image was then obtained by a PET camera, and the standardized uptake ratio (SUR) was computed for each muscle. The SUR for each muscle of the walking group was compared with that for the corresponding muscles in the resting group. The level of muscular activity of all the muscles we examined were higher during level walking than when resting. The activity of the lower leg muscles was higher than that of the thigh muscles during level walking. The muscular activity of the soleus was highest among all the muscles examined. Among the gluteal muscles, the muscular activity of the gluteus minimus was higher than that of the gluteus maximus and gluteus medius. The concurrent validity of measuring muscular activity of the lower extremity during level walking by the PET method using 18 F-FDG was demonstrated. (author)

    This paper reports results on an indoor air quality study conducted on six homes in summer and winter, contrasting indoor and outdoor concentrations of O3, CO, CO2, NOx, PM2.5, and selected volatile organic hydrocarbons measured by PTR-MS. Data were collected as 1 minute averages. Air exchange rates of the homes were determined by CO2 tracer release. Smart home sensors, recording human activity level in various places in the home, and window and doors openings, were utilized to better understand the link between human activity and indoor air pollution. From our study, averaged air exchange rates of the homes ranged from 0.2 to 1.2 hour-1 and were greatly affected by the ventilation system type and window and door openings. In general, a negative correlation between air exchange rate and indoor VOCs levels was observed, with large variation of pollutant levels between the homes. For most of the VOCs measured in the house, including formaldehyde and acetaldehyde, summer levels were much higher than winter levels. In some homes formaldehyde levels displayed a time of day variation that was linked to changes in indoor temperature. During a wildfire period in the summer of 2015, outdoor levels of PM2.5, formaldehyde, and benzene dramatically increased, significantly impacting indoor levels due to infiltration. Human activities, such as cooking, can significantly change the levels of most of the compounds measured in the house and the levels can be significantly elevated for short periods of time, with peak levels can be several orders higher compared with typical levels. The data suggest that an outcome of state energy codes that require new homes to be energy efficient, and as a consequence built with lower air exchange rates, will be unacceptable levels of air toxics, notably formaldehyde.

    COPD is associated with a gradual decline in physical activity, which itself contributes to a worsening of the underlying condition. Strategies that improve physical activity levels are critical to halt this cycle. Wearable sensor based activity monitoring and persuasive feedback might offer a potential solution. However it is not clear just how much intervention might be needed in this regard - i.e. whether programmes need to be tailored specifically for the target clinical population or whether more simple activity monitoring and feedback solutions, such as that offered in consumer market devices, might be sufficient. This research was carried out to investigate the impact of 4 weeks of using an off the shelf consumer market activity monitoring and feedback application on measures of physical activity, exercise capacity, and health related quality of life in a population of 10 Stage I and II COPD patients. Results demonstrate a significant and positive effect on exercise capacity (measured using a 6-minute walk test) and activity levels (measured in terms of average number of steps per hour) yet no impact on health related quality of life (St Georges Respiratory Disease Questionnaire).

    Full Text Available The study aimed to identify stress levels, areas and their activities identified as stressful by nurses working in the emergence in Manaus, AM, Brazil. It is an epidemiological, cross-sectional design, with 36 emergency nurses from December 2010 to January 2011. The Bianchi Stress Scale with 57 questions was used. The nurses were at risk for high levels of stress. The most stressful areas were the operation of the unit, conditions of work and personnel administration, and the most stressful activity was the request for equipment review and repair. The difference by Friedman test between the areas was significant (p <0.05, Dunn post-test significant (p <0.05 when compared by peers. The accumulation of management activities with the assistance activities can generate higher levels of stress, it is necessary to invest in improving the work environment and management support to minimize the stress experienced at work.

    Gastroesophageal reflux disease (GERD) is a very frequent and multifactorial disease. It has been found that GERD is associated with obesity, smoking, esophagitis, diet and lifestyle. Physical activity is among the factors involved in the occurrence of GERD. The aim of the study was to evaluate the associations between the different parameters of lower esophageal pressure (LES) and the level of everyday physical activity in patients with GERD. The authors examined 100 consecutive patients who underwent manometry and pH-metry because of symptoms suggesting GERD. Physical activity was assessed by means of the International Physical Activity Questionnaire (IPAQ). In accordance with IPAQ categorical scoring, the authors divided the studied subjects into 3 groups according to their level of physical activity. The investigation comprised 59 men and 41 women, with the mean age 49 ± 14 years. The authors analyzed the relationships between the LES parameters (pressure, total LES length and HPZ length) and physical activity. The authors did not find any significant correlations between the studied parameters and the amount of physical activity. The authors also did not observe any association between the LES pressure and the level of physical activity. The subgroups distinguished on the basis of LESP did not differ as to the amount of everyday physical activity as well. Although most data indicates that intense exercise exacerbates GERD symptoms, the authors did not find any associations between LES parameters and physical activity. In view of the present results maintaining the recommended level of everyday physical activity does not interfere with the mechanisms of GERD.

    Mindfulness-based interventions have been increasingly applied to treat eating-related problems ranging from obesity to eating disorders. Yet few studies have empirically examined the mechanisms of a mindful approach to eating. The current studies examine the potential of brief mindfulness instructions to enhance the psychological and behavioral dimensions of eating. In three experiments (total N = 319 undergraduates), we examined whether brief mindfulness instructions would enhance the positive sensory experience involved in tasting food as well as healthy eating behaviors. Relative to distraction control instructions, the first two studies demonstrated that brief mindfulness instructions increased the enjoyment of a commonly pleasurable food (chocolate; Study 1), and a food with generally more mixed associations (raisins; Study 2). The third study replicated and extended these findings to show that brief mindfulness instructions also led to lower calorie consumption of unhealthy food relative to distracted or no-instruction control conditions, an effect mediated by greater eating enjoyment. Findings demonstrated the power of brief mindfulness instructions to positively impact both health-relevant behavior and sensory experience associated with eating food. Implications for both theory and clinical applications of mindfulness are discussed. Copyright © 2016 Elsevier Ltd. All rights reserved.

    Highlights: ► Ion beam bombarded rice seeds in vacuum. ► Studied seed survival from the ion bombardment. ► Determined various antioxidant enzyme activities and lipid peroxidation level. ► Discussed vacuum, ion species and ion energy effects. ► Attributed the changes to free radical formation due to ion bombardment. -- Abstract: Low-energy ion beam bombardment has been used to mutate a wide variety of plant species. To explore the indirect effects of low-energy ion beam on biological damage due to the free radical production in plant cells, the increase in antioxidant enzyme activities and lipid peroxidation level was investigated in ion-bombarded rice seeds. Local rice seeds were bombarded with nitrogen or argon ion beams at energies of 29–60 keV and ion fluences of 1 × 10{sup 16} ions cm{sup −2}. The activities of the antioxidant enzymes; superoxide dismutase (SOD), catalase (CAT), ascorbate peroxidase (APX), dehydroascorbate reductase (DHAR), glutathione reductase (GR), glutathione S-transferase (GST) and lipid peroxidation level were assayed in the germinated rice seeds after ion bombardment. The results showed most of the enzyme activities and lipid peroxidation levels in both the argon and nitrogen bombarded samples were higher than those in the natural control. N-ion bombardment could induce higher levels of antioxidant enzyme activities in the rice samples than the Ar-ion bombardment. Additional effects due to the vacuum condition were found to affect activities of some antioxidant enzymes and lipid peroxidation level. This study demonstrates that ion beam bombardment and vacuum condition could induce the antioxidant enzyme activity and lipid peroxidation level which might be due to free radical production in the bombarded rice seeds.

    Full Text Available BackgroundMetabolic dysfunctions characteristic of overt hypothyroidism (OH start at the early stage of subclinical hypothyroidism (SCH. Na+/K+-ATPase (the sodium pump is a transmembrane enzyme that plays a vital role in cellular activities in combination with membrane lipids. We evaluated the effects of early changes in thyroid hormone and membrane cholesterol on sodium pump activity in SCH and OH patients.MethodsIn 32 SCH patients, 35 OH patients, and 34 euthyroid patients, sodium pump activity and cholesterol levels in red blood cell membranes were measured. Serum thyroxine (T4 and thyroid stimulating hormone (TSH levels were measured using enzyme-linked immunosorbent assays. Differences in their mean values were analysed using post hoc analysis of variance. We assessed the dependence of the sodium pump on other metabolites by multiple regression analysis.ResultsSodium pump activity and membrane cholesterol were lower in both hypothyroid groups than in control group, OH group exhibiting lower values than SCH group. In SCH group, sodium pump activity showed a significant direct dependence on membrane cholesterol with an inverse relationship with serum TSH levels. In OH group, sodium pump activity depended directly on membrane cholesterol and serum T4 levels. No dependence on serum cholesterol was observed in either case.ConclusionDespite the presence of elevated serum cholesterol in hypothyroidism, membrane cholesterol contributed significantly to maintain sodium pump activity in the cells. A critical reduction in membrane cholesterol levels heralds compromised enzyme activity, even in the early stage of hypothyroidism, and this can be predicted by elevated TSH levels alone, without any evident clinical manifestations.

    Full Text Available BACKGROUND: Many studies and scientific evidence confirm a positive effect of physical activity on the quality of life and human health. Physical activity, which is also one of the key factors preventing mass non-communicable diseases, is decreasing in Europe, including the Czech Republic, both in children and adults. Serious health consequences for the population and economy of the countries are a reason for a discussion about including the low level of physical activity among public policy issues and a higher allocation of public sources into the area of physical activity promotion. OBJECTIVES: The main objective of the paper is to determine whether the low level of physical activity is a public policy issue. An issue that should by systematically addressed by national, regional as well as local policy. METHODS: Through the policy analysis approach we conducted a content analysis of 25 systematically selected foreign national strategies aimed at the issue of physical activity promotion. The data source was an internal database of the World Health Organization - the International Inventory of Documents on Physical Activity Promotion. The content analysis of the strategies was performed using the Atlas.ti software tool. RESULTS: During a content analysis of 25 foreign strategies a total of 411 text segments (quotations relating to the low level of physical activity were selected. These text segments showed five basic features of a public policy issue according to a conceptual framework developed by Bardach (2000 and Patton and Sawicky (1993 - 1 affects the lives of a significant number of people of a society; 2 is analysable; 3 can be solved through public policy tools; 4 the primary cause or problem can be defined; 5 cannot be solved easily and quickly. CONCLUSIONS: The results indicate that the low level of physical activity is a public policy issue that must be systematically addressed at national level.

    Hip fractures are very common in older adults and result in serious health consequences. Early mobilization post-surgical intervention for hip fractures is very important. The purpose of this study was to determine physical activity levels during an acute inpatient admission of patients after surgery for hip fracture. The observational study was completed on an orthopaedic ward in an acute general hospital. Twenty patients (18 women, mean age ± standard deviation, 79.1 ± 9.3 years) post-surgical intervention for a hip fracture were included. Physical activity levels were measured using an accelerometer to record the percentage of time spent in lying/sitting, standing and walking, number of steps taken and average energy expenditure. Physical activity levels were extremely low, with participants spending an average of 99% of the day either lying or sitting and a little more than 1% of the day either standing or walking (16 min). Participants took an average of 35.7 ± 80.4 steps per day. Patients received more physiotherapy intervention on weekdays compared with weekends. There was no significant difference in activity levels between weekdays to weekends. No measures of physical activity were associated with length of stay. A mild to moderate association (r = 0.26-0.41) was observed between the measures of physical activity and the amount of physiotherapy received during the weekdays. Physical activity levels during an acute inpatient admission surgery for hip fracture are very low. Patients may have difficulty completing basic activities of daily living post-discharge into the community. Physical activity should be optimized as early in the rehabilitation process as able.

    The objective of this study was to analyze the physical activity patterns of women living in a low-income community located in close proximity to the 2016 Rio de Janeiro Olympic Park. Data (N = 140) were collected in June and July 2012 using the International Physical Activity Questionnaire. Findings indicated that the majority (54.8%) of participants reported high levels of physical activity. The domains that contributed the most to this pattern were occupational and household physical activity. Significantly, 88.1% of participants reported low physical activity levels during their leisure-time. In the transport-related domain, participants were relatively more active, but more than half of them (57%) spent less than 600 MET-minutes/week in this domain. The results highlighted the discrepancies between different physical activity domains. In addition, the findings also suggested that low-income women in our study engaged little in physical activity during their leisure time. Therefore, the proposed commitments found in the Rio de Janeiro Candidature File to host the 2016 Olympic Games to increase sport/physical activity participation within low-income communities in Rio de Janeiro need to be implemented effectively if this physical activity behavior during self-directed time is to be changed.

    Full Text Available The aim of this study is to identify the educational administrators’ technological leadership efficacy (TLE and perceptions towards implementation levels of teaching and learning activities (ITLA, and then to present the contribution of the TLE as a predictor of the ITLA. We collected data from 112 educational administrators who are working in Tokat. According to the results of this study, educational administrators’ TLE level was “adequate” for only Digital age learning culture, for the other factors and the total of the TLE levels were “intermediate” level. According to ITLA results, all the sub-factors and total of the scale were “strongly agree” level. The technological leadership efficacy and perceptions towards implementation levels of teaching and learning activities differ according to educational administrators’ age, school type and working in town/city. There is a positive, medium level and significant correlation between educational administrators’ total scores of the TLE and ITLA. A simple linear regression was calculated to predict administrators’ perceptions towards implementation levels of teaching and learning activities based on their technological leadership efficacy, and TLE explains only 29% of the variation in ITLA.

With this purpose, it was administered the questionnaire PACE (Physician-based Assessment and Counseling for Exercise in a sample of 85 schoolchildren (44 from Spain and 41 from India. The results showed that the sample studied does not do enough physical activity, according to the recommendations of the World Health Organization, as they do at least 60 minutes of physical activity; only an average of 3.13 days/week (SD=1.91. 8-year-old schoolchildren do more physical activity than 9-year-old schoolchildren in both countries; boys do more physical activity than girls in both countries; schoolchildren from India do more physical activity than schoolchildren from Spain. Therefore, it is concluded that the level of physical activity is insufficient, decreases slightly with the age and is higher in India.

    Physical inactivity among children is a serious public health problem. It has been suggested that high levels of screen time are contributory factors that encourage sedentary lifestyles in young people. As physical inactivity and obesity levels continue to rise in young people, it has been proposed that new-generation active computer- and video-console games (otherwise known as "exergaming") may offer the opportunity to contribute to young people's energy expenditure during their free time. Although studies have produced some encouraging results regarding the energy costs involved in playing active video-console games, the energy costs of playing the authentic versions of activity-based video games are substantially larger, highlighting that active gaming is no substitute for real sports and activities. A small number of exergaming activities engage children in moderate-intensity activity, but most do not. Only 3 very small trials have considered the effects of exergaming on physical activity levels and/or other health outcomes in children. Evidence from these trials has been mixed; positive trends for improvements in some health outcomes in the intervention groups were noted in 2 trials. No adequately powered randomized, controlled trial has been published to date, and no trial has assessed the long-term impact of exergaming on children's health. We now need high-quality randomized, controlled trials to evaluate the effectiveness and sustainability of exergaming, as well as its clinical relevance; until such studies take place, we should remain cautious about its ability to positively affect children's health.

    Some religions espouse doctrines that (in)directly impact physical activity (PA) behavior. Yet limited PA interventions have been tailored to religious minorities. Thus, a formative study was conducted to examine the effect of a faith-based pedometer program (Virtual Umra) on psychological correlates of PA behavior and their contribution to school-time changes in PA among Muslim adolescents. Forty-three (27 girls, 16 boys; M(age) = 12.3 +/- 1.0 years) students at 1 Islamic middle school participated. Prebaseline and postprogram enjoyment and motivation were measured using the shortened PA Enjoyment Scale and the Situational Motivation Scale, respectively. Pedometer step counts were measured daily during a 2-week baseline and 8 weeks of Virtual Umra. The Reliable Change Index and Cohen's d were used to analyze individual- and group-level changes in enjoyment and motivation, respectively. Repeated-measures multivariate analysis of variance (RM-MANOVA) was used to analyze program and gender effects over time. Partial correlations examined the relationships between psychological correlates and PA change. One third of the sample expressed greater enjoyment postprogram (p motivation was unaffected (p > .05; range, d = - 0.02 to 0.32). RM-MANOVA revealed that boys increased their steps, whereas girls reduced their step number through the program. Enjoyment increased and extrinsic motivation and amotivation decreased. Partial correlations revealed that enjoyment and more self-determined behavioral regulations were positively associated with non-physical education (PE)-day PA change; only intrinsic motivation was positively associated with PE-day PA change. Virtual Umra was associated with increased enjoyment of PA but needs further modification to more positively impact girls' PA.

  17. Moderate levels of activation lead to forgetting in the think/no-think paradigm.

    Using the think/no-think paradigm (Anderson & Green, 2001), researchers have found that suppressing retrieval of a memory (in the presence of a strong retrieval cue) can make it harder to retrieve that memory on a subsequent test. This effect has been replicated numerous times, but the size of the effect is highly variable. Also, it is unclear from a neural mechanistic standpoint why preventing recall of a memory now should impair your ability to recall that memory later. Here, we address both of these puzzles using the idea, derived from computational modeling and studies of synaptic plasticity, that the function relating memory activation to learning is U-shaped, such that moderate levels of memory activation lead to weakening of the memory and higher levels of activation lead to strengthening. According to this view, forgetting effects in the think/no-think paradigm occur when the suppressed item activates moderately during the suppression attempt, leading to weakening; the effect is variable because sometimes the suppressed item activates strongly (leading to strengthening) and sometimes it does not activate at all (in which case no learning takes place). To test this hypothesis, we ran a think/no-think experiment where participants learned word-picture pairs; we used pattern classifiers, applied to fMRI data, to measure how strongly the picture associates were activating when participants were trying not to retrieve these associates, and we used a novel Bayesian curve-fitting procedure to relate this covert neural measure of retrieval to performance on a later memory test. In keeping with our hypothesis, the curve-fitting procedure revealed a nonmonotonic relationship between memory activation (as measured by the classifier) and subsequent memory, whereby moderate levels of activation of the to-be-suppressed item led to diminished performance on the final memory test, and higher levels of activation led to enhanced performance on the final test.

    We aimed to identify demographic and health-related predictors of declining physical activity levels over a four-year period among participants in the Childhood Cancer Survivor Study. Analyses included 7,287 ≥5-year childhood cancer survivors and 2,107 siblings who completed multiple follow-up questionnaires. Participants were classified as active if they met the Centers for Disease Control and Prevention guidelines for physical activity. Generalized linear models were used to compare participants whose physical activity levels declined from active to inactive over the study to those who remained active. In addition, selected chronic conditions (CTCAE v4.03 Grade 3 and 4) were evaluated as risk factors in an analysis limited to survivors only. The median age at last follow-up among survivors and siblings was 36 (range, 21-58) and 38 (range, 21-62) years, respectively. The rate of decline did not accelerate over time among survivors when compared with siblings. Factors that predicted declining activity included body mass index ≥30 kg/m(2) [RR = 1.32; 95% confidence interval (CI), 1.19-1.46, P physical activity levels were associated with the presence of chronic musculoskeletal conditions (P = 0.034), but not with the presence of cardiac (P = 0.10), respiratory (P = 0.92), or neurologic conditions (P = 0.21). Interventions designed to maximize physical activity should target female, obese, and less educated survivors. Survivors with chronic musculoskeletal conditions should be monitored, counseled, and/or referred for physical therapy. Clinicians should be aware of low activity levels among subpopulations of childhood cancer survivors, which may heighten their risk for chronic illness. ©2014 American Association for Cancer Research.

    Physical inactivity is an important risk factor for stroke and stroke recurrence. There is insufficient knowledge about the physical activity (PA) level in stroke patients who are ambulatory in the subacute phase. Our aim was to compare the PA level between ambulatory stroke patients and a population of the same age and to investigate neuropsychological factors that could affect the PA level in the same stroke group. Eighty-five subacute stroke patients and 58 healthy subjects were included. Patients' demographic features, disease-related features, and comorbidities were recorded. The PA level was assessed by the International Physical Activity Questionnaire-Short Version and a pedometer (OMRON Walking style II). The Apathy Rating Scale was applied to determine the apathy level. Depression level was investigated by the Geriatric Depression Scale. The standardized Mini-mental State Examination was performed to assess the cognitive status. The PA level was significantly higher in the healthy group than in the stroke group (plevel of men was significantly higher than that of women (p=0.03). Participants who were classified as level 4 had a lower PA level than those who were classified as level 5 according to the Functional Ambulation Category. There was no relationship between the PA level and the apathy, cognitive, and depression levels in the stroke patients (p>0.05). Subacute stroke patients have a lower PA level than healthy subjects. This is not related to neuropsychological factors. The reasons for minor deficits related to ambulation should be researched further while developing strategies for increasing the PA level of subacute stroke patients.

    An automatic procedure to keep updated the activity levels each radionuclide existing in a radioactivity laboratory, and its classification according to the Spanish Regulations on Nuclear and Radioactive Establishments is described. This procedure takes into account the mixed composition of each source and whether it is sealed or the activity and mass variation due to extraction or evaporation in non-sealed sources. For a given date and time, the procedure prints out a complete listing of the activity of each radioactive source, the accumulated activity for each radionuclide, for each kind of radionuclide and the actual classification of the laboratory according to the legal regulations above mentioned.

    Growing evidence suggests that testosterone may play a role in the pathophysiology of schizophrenia given that testosterone has been linked to cognition and negative symptoms in schizophrenia. Here, we determine the extent to which serum testosterone levels are related to neural activity in affective processing circuitry in men with schizophrenia. Functional magnetic resonance imaging was used to measure blood-oxygen-level-dependent signal changes as 32 healthy controls and 26 people with schizophrenia performed a facial emotion identification task. Whole brain analyses were performed to determine regions of differential activity between groups during processing of angry versus non-threatening faces. A follow-up ROI analysis using a regression model in a subset of 16 healthy men and 16 men with schizophrenia was used to determine the extent to which serum testosterone levels were related to neural activity. Healthy controls displayed significantly greater activation than people with schizophrenia in the left inferior frontal gyrus (IFG). There was no significant difference in circulating testosterone levels between healthy men and men with schizophrenia. Regression analyses between activation in the IFG and circulating testosterone levels revealed a significant positive correlation in men with schizophrenia (r=.63, p=.01) and no significant relationship in healthy men. This study provides the first evidence that circulating serum testosterone levels are related to IFG activation during emotion face processing in men with schizophrenia but not in healthy men, which suggests that testosterone levels modulate neural processes relevant to facial emotion processing that may interfere with social functioning in men with schizophrenia.

    Obesity is a growing public health issue. One of the main strategies to prevent it is physical activity. To determine if a correlation exists between awareness of the consequences of obesity and physical activity level. A cross-sectional study performed on a group of 215 students was conducted in 2013 and 2014. Non-health related program students were selected by convenience sampling at a university in Lima, Peru. Their physical activity level was measured using the International Physical Activity Questionnaire (IPAQ), and knowledge about the consequences of obesity was assessed using the Obesity Risk Knowledge-10 scale (ORK-10). Each student was also asked to record the source where they obtained whatever information they knew about the topic. The median age of the participants was 20 (interquartile range of 4; 22-18), and 63% of the participants were female. According to the IPAQ, 53.9% of the participants recorded high levels of physical activity, 35.4% recorded moderate levels, and 10.7%, recorded low levels. While a low correlation between the ORK-10 score and the amount of METs/minute/week spent was found (rs=0.06), it was not significant (p=0.38). We found that people who were informed by the media or by healthcare personnel achieved higher scores on the ORK-10 scale than those who used other sources of information (p<0,05). There is a very low correlation between the knowledge about the consequences of obesity and a person’s physical activity level. A multidisciplinary approach that includes all determinants of physical activity is necessary in order to attain changes in people’s behavior.

    Male bluegill displays one of two life history tactics. Some males (termed "parentals") delay reproduction until ca. 7 years of age, at which time they build nests and actively courts females. Others mature precociously (sneakers) and obtain fertilizations by cuckolding parental males. In the current study, we studied the relations among sperm motility, ATP levels, and metabolic enzyme activity in parental and sneaker bluegill. In both reproductive tactics, sperm swimming speed and ATP levels declined in parallel over the first 60 s of motility. Although sneaker sperm initially had higher ATP levels than parental sperm, by approximately 30 s postactivation, no differences existed between tactics. No differences were noted between tactics in swimming speed, percent motility, or the activities of key metabolic enzymes, although sperm from parentals had a higher ratio of creatine phosphokinase (CPK) to citrate synthase (CS). In both tactics, with increasing CPK and CS activity, sperm ATP levels increased at 20 s postactivation, suggesting that capacities for phosphocreatine hydrolysis and aerobic metabolism may influence interindividual variation in rates of ATP depletion. Nonetheless, there was no relation between sperm ATP levels and either swimming speed or percent of sperm that were motile. This suggests that interindividual variation in ATP levels may not be the primary determinant of variation in sperm swimming performance in bluegill.

    Heavy physical activities can cause the oxidative stress which resulting in muscle damage with an indicator of elevated levels of Creatin Kinase (CK) enzyme. The oxidative stress can be prevented or reduced by antioxidant supplementation. One of natural resources which contain antioxidant is Red Fruit (Pandanus conoideus) Oil (RFO). This study aims to see the effect of Red Fruit Oil on Creatin Kinase (CK) level at maximum physical activity. This study is an experimental research by using the design of randomized control group pretest-posttest. This study was using 24 male mice divided into four groups, the control group was given aquadest, the treatment groups P1, P2, and P3 were given the RFO orally of 0.15 ml/kgBW, 0.3 ml/kgBW, and 0.6 ml/kgBW, respectively, for a month. The level of CK was checked for all groups at the beginning of study and after the maximum physical activity. The obtained data were then tested statistically by using t-test and ANOVA. The result shows the RFO supplementation during exercise decreased the CK level in P1, P2, and P3 groups with p<0.05, and the higher RFO dosage resulted in decreased CK level at p<0.05. The conclusion of this study is the Red Fruit Oil could decrease the level of CK at maximum physical activity.

    Reduced oxygen (O 2 ) levels (hypoxia) are present during embryogenesis and exposure to altitude and in pathologic conditions. During embryogenesis, myogenic progenitor cells reside in a hypoxic microenvironment, which may regulate their activity. Satellite cells are myogenic progenitor cells localized in a local environment, suggesting that the O 2 level could affect their activity during muscle regeneration. In this review, we present the idea that O 2 levels regulate myogenesis and muscle regeneration, we elucidate the molecular mechanisms underlying myogenesis and muscle regeneration in hypoxia and depict therapeutic strategies using changes in O 2 levels to promote muscle regeneration. Severe hypoxia (≤1% O 2 ) appears detrimental for myogenic differentiation in vitro, whereas a 3-6% O 2 level could promote myogenesis. Hypoxia impairs the regenerative capacity of injured muscles. Although it remains to be explored, hypoxia may contribute to the muscle damage observed in patients with pathologies associated with hypoxia (chronic obstructive pulmonary disease, and peripheral arterial disease). Hypoxia affects satellite cell activity and myogenesis through mechanisms dependent and independent of hypoxia-inducible factor-1α. Finally, hyperbaric oxygen therapy and transplantation of hypoxia-conditioned myoblasts are beneficial procedures to enhance muscle regeneration in animals. These therapies may be clinically relevant to treatment of patients with severe muscle damage.-Chaillou, T. Lanner, J. T.

    Full Text Available Sport and physical activity is important and compulsory for military staff. They determine the execution of service duties and tasks. Respondents with low level of physical activity have difficulties achieving required fitness level and pass the annual physical tests. Staff officers aged 28 to 40 years completed questionnaires in 2009 (n=22, 2010 (n=30 and 2012 (n=39. Each questionnaire included twenty one questions which were then evaluated in points. The answers allowed us to collect information regarding their physical activity during service hours as well as after the working day. Questionnaires included also issues on harmful habits – sleep duration, smoking and use of alcohol; self-esteem of body mass as well. The respondents were divided into four groups according to the level of physical activity: low, moderate, good, high. The percentage of respondents with a high and good level of physical activity has increased from 22.7% to 68.9% during the analysed time period. Morning exercises and hardening (fitness procedures were not popular for military personnel. However, physical activities during the working hours have slightly increased: 31.8%, 43.3% and 48.9.3% respectively. In study years, it was found that respondents try to follow healthy eating habits and sleep regime. There is a slight decrease of respondents with obese and there is a slight increase of 22.7% to 27.6% of the respondents who are regular smokers .

    Full Text Available Aims: Recently, homocysteine has been noticed as the major pathogenesis factor of the cardiovascular diseases. The aim of the study was to investigate the effects of physical activities on the serum homocysteine levels, as well as other cardiovascular risk factors in either obese or overweight women. Materials & Methods: In the controlled pretest-posttest semi-experimental study, 18 women referred to the Alzahra sport complexes in districts 3 and 4 of Tehran were studied in 2015. The subjects were selected via random sampling method and randomly divided into two groups; physical activity and control groups. And the intervention program was conducted in the former, while the latter received no intervention. The exercise protocol consisted of 10-week (5 sessions a week stretching exercises and aerobic activities (60 to 75% of the maximum heart beat. The serum homocystein level and lipids were measured both at the start and 48 hours after the exercises. Data was analyzed by SPSS 16 software using paired T and independent T tests. Findings: After the exercises, the mean serum homocysteine level in physical activity group significantly decreased than control group (p=0.001. Nevertheless, the difference between the lipid levels of physical activity and control groups was not significant (p>0.05. Conclusion: Reducing the serum homocysteine concentration, 10-week physical activity might also reduce the risk factors of cardiovascular diseases in either obese or overweight women.

    Full Text Available The present study identified a novel salinomycin (Sal-sensitization mechanism in cancer cells. We analyzed the signal proteins Akt, Jnk, p38, Jak, and Erk1/2 in cancer cell lines that had arrested growth following low amounts of Sal treatment. We also tested the signal molecules PI3K, PDK1, GSK3β, p70S6K, mTOR, and PTEN to analyze the PI3K/Akt/mTOR pathway. The results showed that Sal sensitization positively correlates with large reductions in p70S6K activation. Interestingly, Akt was the only signal protein to be significantly activated by Sal treatment. The Akt activation appeared to require the PI3K pathway as its activation was abolished by the PI3K inhibitors LY294002 and wortmannin. The Akt activation by Sal was conserved in the other cell lines analyzed, which originated from other organs. Both Akt activation and C-PARP production were proportionally increased with increased doses of Sal. In addition, the increased levels of pAkt were not reduced over the time course of the experiment. Co-treatment with Akt inhibitors sensitized the Sal-treated cancer cells. The results thereby suggest that Akt activation is increased in cells that survive Sal treatment and resist the cytotoxic effect of Sal. Taken together; these results indicate that Akt activation may promote the resistance of cancer cells to Sal.

    Pain and reduced physical activity levels are common in children with juvenile idiopathic arthritis (JIA). Currently, there is no consensus about the role of physical activity in managing pain in JIA. The purpose of our study was to assess the relationship between physical activity level and pain in children ages 11 to 18 years with JIA. A random sample of 50 patients with JIA were approached by mailed questionnaires. Physical activity was determined using the Physical Activity Questionnaire (PAQ). Pain measures included the Numerical Rating Scale (pain severity), SUPER-KIDZ body diagram (number of painful areas), and the Child Activities Limitations Inventory-21 (pain interference). Generalized linear models were used to assess the relationship between physical activity and pain, as well as the roles of sex and age. The response rate was 84%. Thirty-four respondents completed the questionnaire package. The median age was 15 years. The mean PAQ score was 2.16/5. Physical activity declines with increasing age in youth with JIA (r = 0.53, p = 0.0014). Lower physical activity is associated with greater pain interference (r = 0.39, p = 0.0217) and more severe pain (r = 0.35, p = 0.0422). Children with JIA report significantly less activity than healthy children based on PAQ scores, with physical activity declining throughout adolescence. Physical activity is inversely related to pain interference and severity in children with JIA. Our findings suggest that physical activity interventions may play an important role in the management of pain in JIA.

    Human peroxisomes proliferate-activated receptor gamma (hPPAR{gamma}) has been implicated in numerous pathologies, including obesity, diabetes, and cancer. Previously, we verified that amentoflavone is an activator of hPPAR{gamma} and probed the molecular basis of its action. In this study, we investigated the mechanism of action of amentoflavone in cancer cells and demonstrated that amentoflavone showed strong cytotoxicity against MCF-7 and HeLa cancer cell lines. We showed that hPPAR{gamma} expression in MCF-7 and HeLa cells is specifically stimulated by amentoflavone, and suggested that amentoflavone-induced cytotoxic activities are mediated by activation of hPPAR{gamma} in these two cancer cell lines. Moreover, amentoflavone increased PTEN levels in these two cancer cell lines, indicating that the cytotoxic activities of amentoflavone are mediated by increasing of PTEN expression levels due to hPPAR{gamma} activation.

    Uterine electrical activity is correlated to the appearance of uterine contractions. forceful contractions appear at the end of term. Therefore, understanding the genesis and the propagation of uterine electrical activity may provide an efficient tool to diagnose preterm labor. Moreover, the control of uterine excitability seems to have important consequences in the control of preterm labor. Modeling the electrical activity in uterine tissue is thus an important step in understanding physiological uterine contractile mechanisms and to permit uterine EMG simulation. Our model presented in this paper, incorporates ion channel models at the cell level, the reaction diffusion equations at the tissue level and the spatiotemporal integration at the uterine EMG reconstructed level. This model validates some key physiological observation hypotheses concerning uterine excitability and propagation.

    Previous research on news perception has been dominated by a cognitively oriented perspective on reception processes, whereas emotions have been widely neglected. Consequently, it has remained open which features of a news story might elicit affective responses and hence modulate news perception, shifting the focus to the emotional potential of the narrative. According to the affective-disposition theory, the experience of suspense is the striving force of immersion in fictional dramas. Thereby, a positive affective disposition toward the protagonist of a story and a high likelihood of a bad ending should increase suspense that, in turn, should positively influence reading appreciation and lingering interest in the story. We investigated whether suspense and its determinants also play such a key role in the context of news stories. Study 1 ( n = 263) successfully replicated results of an earlier study, whereas Studies 2 ( n = 255) and 3 ( n = 599) challenged the generalizability of some effects related to manipulated characteristics of a news story. In contrast, correlational relationships between perceived news characteristics and news evaluation were relatively stable. In particular, participants' liking of the protagonist and the perceived likelihood of a good ending were positively associated with suspense, reading appreciation, and lingering interest. This result indicates a preference for happy endings and contradicts the notion that likely negative outcomes are beneficial for suspense and the enjoyment of news stories, as postulated by the affective-disposition theory in the context of fictional dramas. Moreover, experienced suspense reliably mediated the correlations between, on the one hand, participants' liking of the protagonist and the perceived likelihood of a good ending and, on the other hand, reading appreciation and lingering interest. The news story's personal relevance was less influential than expected. Further, we observed a large absence of

    There is limited research on the role of enjoyment of exercise among people with arthritis. The aim of the present study was to determine distinct viewpoints on exercise held by people with arthritis, and how enjoyment features in these viewpoints. A Q-methodology study was conducted, which involved two interviews with people with rheumatoid arthritis, osteoarthritis or ankylosing spondylitis (aged 20-85 years). In the first interviews, 11 participants helped to create the Q-set, a set of statements reflecting a range of existing views on exercising. In the second interviews, 12 participants (nine of the 11 from the first interviews and three others) ranked the Q-set on a forced quasi-normal distribution of agreement. A Q-method factor analysis was carried out to determine groupings of participants with similar views on exercise. Four groupings were discovered, and defined in terms of rankings of statements and illustrative quotes from the ranking procedure. The first grouping had all changed their exercise habits after diagnosis with arthritis. The second grouping had a shared enjoyment for walking to stay healthy. The third grouping's viewpoints focused on knowledge about how much exercise they should carry out. The fourth grouping shared a sense of importance of being responsible for their health by exercising. These findings provide information about the role that enjoyment plays in motivating people with arthritis to exercise, although enjoyment of exercise was not expressed by all participants. People with arthritis who share these viewpoints on exercise enjoyment may require different forms of advice regarding feasible and enjoyable exercise. Copyright © 2016 John Wiley & Sons, Ltd.

    Full Text Available Antagonistic muscle pairs cannot be fully activated simultaneously, even with maximal effort, under conditions of voluntary co-contraction, and their muscular activity levels are always below those during agonist contraction with maximal voluntary effort (MVE. Whether the muscular activity level during the task has trainability remains unclear. The present study examined this issue by comparing the muscular activity level during maximal voluntary co-contraction for highly experienced bodybuilders, who frequently perform voluntary co-contraction in their training programs, with that for untrained individuals (nonathletes. The electromyograms (EMGs of biceps brachii and triceps brachii muscles during maximal voluntary co-contraction of elbow flexors and extensors were recorded in 11 male bodybuilders and 10 nonathletes, and normalized to the values obtained during the MVE of agonist contraction for each of the corresponding muscles (% EMGMVE. The involuntary coactivation level in antagonist muscle during the MVE of agonist contraction was also calculated. In both muscles, % EMGMVE values during the co-contraction task for bodybuilders were significantly higher (P<0.01 than those for nonathletes (biceps brachii: 66±14% in bodybuilders vs. 46±13% in nonathletes, triceps brachii: 74±16% vs. 57±9%. There was a significant positive correlation between a length of bodybuilding experience and muscular activity level during the co-contraction task (r = 0.653, P = 0.03. Involuntary antagonist coactivation level during MVE of agonist contraction was not different between the two groups. The current result indicates that long-term participation in voluntary co-contraction training progressively enhances muscular activity during maximal voluntary co-contraction.

    There are diverse experimental data about the influence of gemfibrozil (GEM) on the production of hydrogen peroxide (H(2)O(2)) and antioxidant enzymes. We investigated the influence of GEM treatment on the production of malondialdehyde (MDA) level in tissues of normolipidaemic Wistar and Fisher rats which is an index of lipid peroxidation. Because serum paraoxonase 1 (PON1) is an important enzyme with specific protective function on metabolism of lipid peroxides, we examined the influence of GEM on PON1 activity in liver and serum. MDA level and enzyme activities were also determined 10 days after withdrawal of GEM treatment. The significantly increased levels of MDA in liver, kidney and heart of both rat strains were obtained after 3 weeks of GEM treatment. We propose two possibilities for the increase of MDA levels caused by GEM, induction of peroxisome proliferation and activities of enzymes that participated in occurrence of H(2)O(2) and possible reduction of enzyme activities including in H(2)O(2) metabolism. Ten days after withdrawal of GEM treatment, MDA levels in all tissue levels of both rat strains were less in comparison with GEM treatment. GEM caused a significant drop of PON1 activity in serum and liver of Fisher rats, and in liver of Wistar rats. We suggest that GEM, through induction of lipid peroxidation, caused the damage of hepatocytes with consequent reduction of PON1 synthesis. The increase in PON1 activity in serum and tissues of both rat strains 10 days after withdrawal of GEM treatment shows the fast recovery of enzyme synthesis. © 2011 The Authors.

    Full Text Available Abstract Background Women in low-income countries are generally considered to have a high physical workload which is sustained during pregnancy. Although most previous studies have been based on questionnaires a recent meta-analysis of doubly labeled water data has raised questions about the actual amount of physical activity performed. In this study we report objectively assessed levels of physical activity, cardiorespiratory fitness and muscular fitness among pregnant urban Ethiopian women, and their association with demographic characteristics and anthropometric measures. Methods Physical activity was measured for seven consecutive days in 304 women using a combined uniaxial accelerometer and heart rate sensor. Activity energy expenditure was determined using a group calibration in a branched equation model framework. Type and duration of activities were reported using a 24-hour physical activity recall and grip strength was assessed using a dynamometer. Results Median (interquartile-range, IQR activity energy expenditure was 31.1 (23.7-42.0 kJ/kg/day corresponding to a median (IQR physical activity level of 1.46 (1.39-1.58. Median (IQR time in sedentary, light, and moderate-to-vigorous intensity was 1100 (999–1175, 303 (223–374 and 40 (22–69 min/day, respectively. Mean (standard deviation sleeping heart rate was 73.6 (8.0 beats/min and grip strength was 21.6 (4.5 kg. Activity energy expenditure was 14% higher for every 10 cm2 difference in arm muscle area and 10% lower for every 10 cm2 difference in arm fat area and 10-week difference in gestational age. Conclusion The level and intensity of physical activity among pregnant women from urban Ethiopia is low compared to non-pregnant women from other low income countries as well as pregnant European women from high-income countries.

    To compare the associations between neuromuscular performance and anthropometric characteristics with habitual levels of physical activity in boys and girls during the initial stages of puberty. In a cross-sectional study of 72 healthy children (39 boys and 33 girls) ranging in age from 8 to 14 years, sex differences in anthropometric and motor performance characteristics were compared at 3 Tanner stages (T1-T3). Outcome variables included dual-energy x-ray absorptiometry measurements of body composition, assessments of neuromuscular function, and levels of physical activity (steps/day) measured by accelerometry. Physical activity was lower in girls than boys at T2 and T3, but there was no sex difference at T1. Physical activity increased with Tanner stage for boys but did not differ between Tanner stages in girls. Physical activity at each Tanner stage was strongly associated (R(2) > 0.85) with neuromuscular characteristics for both boys and girls, but percentage of body fat also was associated with physical activity for T3 girls. The attenuated gains in neuromuscular function experienced by girls in early stages of puberty were strongly associated with lower levels of physical activity, whereas the increase in physical activity exhibited by boys was mostly related to increases in the strength and endurance of leg muscles. Because sedentary activity is a known contributor to the development of obesity and type 2 diabetes in youth, this study helps to identify possible contributors to decreases in physical activity in young girls and provides potential targets for early intervention.

    Full Text Available Salt-marsh soils are soils characterized by non-permanent hydric saturation that, depending on factors like duration of submersion periods, are dominated by different salt-tolerant plant species. The composition of microbial communities is an essential component in trophic dynamics and biogeochemical processes in salt marshes, and determines the level of enzymatic activities, which catalyze the conversion of complex molecules into simpler ones. Despite of this, the enzymatic activities in marsh-soils has not yet been investigated. The aim of this study was to analyze the enzymatic activities in two soil profiles of marsh-soils under different water saturation level and dominated by different plant species [Juncus maritimus Lam and Spartina maritima (Curtis Fernald (Sp]. In both soils, the enzymatic activities were much lower than the levels typically found in terrestrial ecosystems. The enzymatic activities were measured both in air-dried and in re-moistened and incubated soil samples. In air-dried samples, the enzymatic activities were higher in Juncus than in Spartina soil and tended to decrease with depth, being sharper the decrease in Juncus than in Spartina soil. Re-moistened and pre-incubated soils showed a general increase in all the enzymatic activities and throughout the whole soil profile, especially in Spartina soils. Hydrolase activities showed a strong and positive relationship with organic matter content both in air-dried and in re-moistened soil samples, higher in these latter. In general, oxidoreductase activities only showed this relationship in re-moistened soil samples. More studies, preferably using freshly collected soil samples, are needed to understand the relationship between enzymatic activities and these environmental conditions.

    Little evidence exists on the physical activity and sedentary time of Canadian toddlers; this study objectively measured such behaviors and compared participants' activity levels to national guidelines. Levels of screen-viewing among toddlers were also explored. Forty toddlers (mean age = 25.7 months) wore Actical accelerometers for seven consecutive days (15 s epoch). Parents/guardians completed a wear-time log and a demographic and screen-viewing questionnaire. Descriptive analyses were used to determine participants' levels of physical activity and sedentary time, to identify whether toddlers were meeting physical activity/sedentary guidelines, and to explore demographic variables. T-tests were used to assess whether toddlers' activity levels differed based on cut-points applied and various demographic and screen-related variables. Regression analyses were conducted to examine associations between toddlers' sedentary time and screen-viewing levels. Toddlers engaged in 37.27 (SD = 3.79) to 49.40 (SD = 3.29) mins/hr of sedentary time, 9.79 (SD = 2.90) to 18.78 (SD = 3.22) mins/hr of light-intensity physical activity (LPA), 0.82 (SD = 0.72) to 3.95 (SD = 1.93) mins/hr of moderate- to vigorous-intensity physical activity (MVPA), and 10.60 (SD =3.29) to 22.73 (SD = 3.97) mins/hr of total physical activity (TPA), based on the Trost et al. and the Canadian Health Measures Survey (CHMS) cut-points respectively; these rates were significantly different (p physical activity guidelines. No statistically significant differences in sedentary time or physical activity (all intensities) based on sex were reported (p sedentary behavior guidelines on weekdays and weekend days, respectively. The implications of this work suggest that a greater understanding of toddlers' activity patterns is needed; additional mechanisms of promoting active behaviors among this group should be explored.

    The Antarctic ozone hole arises from ozone destruction driven by elevated levels of ozone destroying (active) chlorine in Antarctic spring. These elevated levels of active chlorine have to be formed first and then maintained throughout the period of ozone destruction. It is a matter of debate how this maintenance of active chlorine is brought about in Antarctic spring, when the rate of formation of HCl (considered to be the main chlorine deactivation mechanism in Antarctica) is extremely high. Here we show that in the heart of the ozone hole (16-18 km or 85-55 hPa, in the core of the vortex), high levels of active chlorine are maintained by effective chemical cycles (referred to as HCl null cycles hereafter). In these cycles, the formation of HCl is balanced by immediate reactivation, i.e. by immediate reformation of active chlorine. Under these conditions, polar stratospheric clouds sequester HNO3 and thereby cause NO2 concentrations to be low. These HCl null cycles allow active chlorine levels to be maintained in the Antarctic lower stratosphere and thus rapid ozone destruction to occur. For the observed almost complete activation of stratospheric chlorine in the lower stratosphere, the heterogeneous reaction HCl + HOCl is essential; the production of HOCl occurs via HO2 + ClO, with the HO2 resulting from CH2O photolysis. These results are important for assessing the impact of changes of the future stratospheric composition on the recovery of the ozone hole. Our simulations indicate that, in the lower stratosphere, future increased methane concentrations will not lead to enhanced chlorine deactivation (through the reaction CH4 + Cl → HCl + CH3) and that extreme ozone destruction to levels below ≈ 0.1 ppm will occur until mid-century.

    There has been a rapid increase in the use of technology-based activity trackers to promote behavior change. However, little is known about how individuals use these trackers on a day-to-day basis or how tracker use relates to increasing physical activity. The aims were to use minute level data collected from a Fitbit tracker throughout a physical activity intervention to examine patterns of Fitbit use and activity and their relationships with success in the intervention based on ActiGraph-measured moderate to vigorous physical activity (MVPA). Participants included 42 female breast cancer survivors randomized to the physical activity intervention arm of a 12-week randomized controlled trial. The Fitbit One was worn daily throughout the 12-week intervention. ActiGraph GT3X+ accelerometer was worn for 7 days at baseline (prerandomization) and end of intervention (week 12). Self-reported frequency of looking at activity data on the Fitbit tracker and app or website was collected at week 12. Adherence to wearing the Fitbit was high and stable, with a mean of 88.13% of valid days over 12 weeks (SD 14.49%). Greater adherence to wearing the Fitbit was associated with greater increases in ActiGraph-measured MVPA (b interaction =0.35, PHartman, Sandahl H Nelson, Lauren S Weiner.

    To find out the optimal nitrogen application level of Desmodium styracifolium. A field experiment using randomized block design was carried out to study the effects of 5 nitrogen application levels (150, 187.5, 225.0, 262.5 and 300.0 kg x hm(-2)) on yield and active component content of D. styracifolium. Nitrogen application could increase the yield and contents of polysaccharide, total flavonoides and total saponins of D. styracifolium. However, the enhancing extent of the active component content and the yield were not always significant with the increase of nitrogen level. In which, the yield were not significantly different among the nitrogen application levels of 225.0, 262.5, 300.0 kg x hm(-2) the polysaccharide content was no significantly difference among the nitrogen application levels of 225.0, 262. 5 and 300.0 kg x hm(-2), the total flavonoides content under the nitrogen level of 300.0 kg x hm(-2) was significantly lower than that of 150.0 kg hm(-2) (P < 0.01), and the total saponins content under the nitrogen level of 300.0 kg x hm(-2) was no significant difference compared with that of 262.5 kg x hm(-2). The optimal nitrogen application level of D. styracifolium was 225.0-262.5 kg x hm(-2).

    Inadequate physical activity has adverse health consequences among adolescents. Mental health problem can be developed by lack of physical activity however it is controversial. The current study aimed to examine the association between level of physical activity with depression, anxiety and stress symptoms among adolescents. A representative sample of 1747 adolescents (13-14 years) was randomly selected from 6 schools in a south part of Malaysia. Respondents were asked to fill consent form, and questionnaires including Depression Anxiety and Stress Scale-21 and Physical Activity Questionnaire for Adolescents. Majority of respondents (71.9%) was Malay and more than half of the adolescents had low physical activity. About 40% had depression symptoms, followed by anxiety symptoms (65.9%) and stress symptoms (38.5%). Level of physical activity was significantly associated with gender, anxiety and stress (P<0.001). There were no associations with race, religion and depression symptom. This study provides some evidence among school-going adolescents related to anxiety and stress symptoms and low physical activities. Further studies are needed to show the protection effects of higher physical activity for depression, anxiety and stress symptoms in adolescents.

    In previous studies the doubly labeled water method for measuring energy expenditure in free-living humans has been validated against respirometry under sedentary conditions. In the present investigation, energy expenditure is measured simultaneously with doubly labeled water and respirometry at low- and high-activity levels. Over 6 days, five subjects were measured doing mainly sedentary activities like desk work; their average daily metabolic rate was 1.40 +/- 0.09 (SD) times sleeping metabolic rate. Four subjects were measured twice over 3.5 days, including 2 days with heavy bicycle ergometer work, resulting in an average daily metabolic rate of 2.61 +/- 0.25 (SD) times sleeping metabolic rate. At the low-activity level, energy expenditures from the doubly labeled water method were on the average 1.4 +/- 3.9% (SD) larger than those from respirometry. At the high-activity level, the doubly labeled water method yielded values that were 1.0 +/- 7.0% (SD) lower than those from respirometry. Results demonstrate the utility of the doubly labeled water method for the determination of energy expenditure in the range of activity levels in daily life

    A neutron activation analysis procedure has been developed for the indirect determination of phosphorus as orthophosphate at ppb levels, via the formation of antimonyl phosphomolybdic acid. The complex is adsorbed on Sephadex G-25 resin and the antimony is estimated through NAA, allowing the determination of phosphorus. The procedure provides an easy method to adopt for the routine determination of phosphorus at ≥ 10 ng ml -1 levels with good precision, in water samples. (author) 6 refs.; 5 tabs

    Hanford Engineering Development Laboratory (HEDL) scientists are involved in studies considering alternative construction materials for the first wall of commercial fusion reactors. To permit a comparison of radioactivity levels, both the level of activation and an acceptable limit for the radionuclides present must be known. Generic material composition guidelines can be developed using the US Nuclear Regulatory Commission (NRC) regulations governing the near-surface disposal of low-level radioactive wastes. These regulations consider wastes defined as containing source, special nuclear, or by-product materials arising from research, industrial, medical, and nuclear fuel-cycle activities. However, not all of the activation products produced in low-level wastes from fusion reactors are considered by the NRC in their regulations. The purpose of this report is to present potential low-level waste-disposal limits for ten radionuclides resulting from fusion reactor operations that are not considered in the NRC low-level waste regulations. These potential limits will be used by HEDL scientists to complete their generic material composition guidelines for the first wall of commercial fusion reactors

Accelerometry counts were highest in the affluent younger group, followed by the deprived younger group, with lowest levels in the deprived over 80 s group. Multiple regression analysis showed that lower age, higher perceived behavioural control, the physical function subscale of SF-36, and having someone nearby to turn to were all independently associated with higher physical activity levels (R(2 = 0.32. In addition, hours of sunshine were independently significantly associated with greater physical activity in a multilevel model.Other than age and hours of sunlight, the variables identified are modifiable, and provide a strong basis for the future development of novel multidimensional interventions aimed at increasing activity participation in later life.

    Descriptions of language production have identified processes involved in producing language and the presence and type of interaction among those processes. In the case of spoken language production, consensus has emerged that there is interaction among lexical selection processes and phoneme-level processing. This issue has received less attention in written language production. In this paper, we present a novel analysis of the writing-to-dictation performance of an individual with acquired dysgraphia revealing cascading activation from lexical processing to letter-level processing. The individual produced frequent lexical-semantic errors (e.g., chipmunk → SQUIRREL) as well as letter errors (e.g., inhibit → INBHITI) and had a profile consistent with impairment affecting both lexical processing and letter-level processing. The presence of cascading activation is suggested by lower letter accuracy on words that are more weakly activated during lexical selection than on those that are more strongly activated. We operationalize weakly activated lexemes as those lexemes that are produced as lexical-semantic errors (e.g., lethal in deadly → LETAHL) compared to strongly activated lexemes where the intended target word (e.g., lethal) is the lexeme selected for production.

    Whether reduced activity level and exercise intolerance precede the clinical diagnosis of cardiopulmonary disorders in smokers is not known. We examined activity level and exercise test outcomes in a young population-based sample without overt cardiopulmonary disease, differentiating by smoking history. This was a multiyear cross-sectional study using United States National Health and Nutrition Examination Survey data from 1999-2004. Self-reported activity level and incremental exercise treadmill testing were obtained on survey participants ages 20-49 years, excluding individuals with cardio-pulmonary disease. Three thousand seven hundred and one individuals completed exercise testing. Compared to never smokers, current smokers with >10 pack years reported significantly higher odds of little or no recreation, sport, or physical activity (adjusted OR 1.62; 95% CI 1.12-2.35). Mean perceived exertion ratings (Borg 6-20) at an estimated standardized workload were significantly greater among current smokers (18.3-18.6) compared to never (17.3) and former smokers (17.9) (psmoking abstinence was associated with significantly lower likelihood of low estimated peak oxygen uptake categorization (psmoking cessation, these results set the stage for future studies that examine mechanisms of activity restriction in young smokers and the utility of measures of activity restriction in the earlier diagnosis of smoking-related diseases.

    To describe an innovative method of developing multiple-choice items for a board certification examination. The development of appropriate multiple-choice items is definitely more of an art, rather than a science. The comedy workshop format for developing questions for a certification examination is similar to the process used by comedy writers composing scripts for television shows. This group format dramatically diminishes the frustrations faced by an individual question writer attempting to create items. The vast majority of our comedy workshop participants enjoy and prefer the comedy workshop format. It provides an ideal environment in which to teach and blend the talents of inexperienced and experienced question writers. This is a descriptive article, in which we suggest an innovative process in the art of creating multiple-choice items for a high-stakes examination.

  20. Access for All! Neuro-architecture and Equal Enjoyment of Public Facilities

    Full Text Available Since the enactment of the Americans with Disabilities Act (ADA, 1990, many impaired Americans are no longer disabled by socially condoned conditions in the built environment. However, many people with cognitive and neurological impairments continue to face significant barriers to access, due to disabling environmental hyper-sensitivity and sensory processing disorders. These people are equally protected under the ADA, therefore mitigation is required. Neuroarchitecture, where consideration of the impact of the built environment on the central nervous system informs design paradigms, must complement current ADA compliance guidelines. This paper serves to open the topic to discussion, and is a call for attention, and action, for the removal of these generally unrecognized barriers to access and the equal use and enjoyment of public facilities.

    Full Text Available Objectives: This study investigated the relationship between urease and arginine deiminase system (ADS activities and dental caries through a cross-sectional study. Material and Methods: Urease and ADS activities were measured in saliva and plaque samples from 10 caries-free subjects and 13 caries-active. Urease activity was obtained from the ammonia produced by incubation of plaque and saliva samples in urea. ADS activity was obtained from the ammonia generated by the arginine-HCl and Tris-maleate buffer. Specific activity was defined as micromoles of ammonia per minute per milligram of protein. Shapiro-Wilk statistical test was used to analyze the distribution of the data, and Mann-Whitney test was used to determine the significance of the data. Results: The specific urease activity in saliva and plaque was significantly higher in individuals with low DMFT scores. ADS activity in saliva (6.050 vs 1.350, p=0.0154 and plaque (8.830 vs 1.210, p=0.025 was also higher in individuals with low DMFT scores. Conclusions: Caries-free subjects had a higher ammonia generation activity by urease and arginine deiminase system for both saliva and plaque samples than low caries-active subjects. High levels of alkali production in oral environment were related to caries-free subjects.

    Physical activity is associated with better health, but many individuals are insufficiently active. Modifying the built environment may be an approach capable of influencing population-wide levels of physical activity, but few data exist from longitudinal studies that can minimize bias from active people choosing activity-friendly neighborhoods. This study aims to examine cross-sectional and longitudinal associations between the built environment and physical activity on a large scale. This study examined cross-sectional associations between urban sprawl (mapping addresses to corresponding counties) and physical activity (self-reported) among men throughout the U.S. in 1993 and in 1988, and longitudinal associations between changes in exposure to urban sprawl for movers and physical activity, 1988-1993. Included were 4997 men (mean age, 70 years) in the 1993 cross-sectional study; 4918 men in the 1988 cross-sectional study; and 3448 men in the longitudinal study, 1988-1993. Data were collected prospectively in 1988 and 1993, and analyses were performed in 2007-2008. In cross-sectional analyses, less sprawl was significantly associated with more walking OR, comparing least with most sprawling areas, for meeting physical activity recommendations by walking=1.38 [95% CI=1.09, 1.76] in 1993 and 1.53 [1.19, 1.96] in 1988). Less sprawl also was associated with lower prevalence of overweight (corresponding OR=0.79 [0.64, 0.98] in 1993 and 0.81 [0.66, 1.00] in 1988). However, longitudinal analyses assessing change did not show that decreasing sprawl was associated with increased physical activity or decreased BMI. These findings suggest that the cross-sectional results may reflect self-selection, rather than indicating that the built environment--as measured by urban sprawl--increases physical activity. However, the longitudinal findings were limited by small numbers of men changing residence and associated sprawl levels.

  3. Supported Decision-Making from Theory to Practice: Implementing the Right to Enjoy Legal Capacity

    2018-04-01

    Full Text Available The right to equal recognition before the law, protected by Article 12 of the United Nations (UN Convention on the Rights of Persons with Disabilities (CRPD, mandates the use of supported decision-making practices to enable disabled people, particularly those with intellectual and/or psychosocial disabilities, to enjoy their legal capacity. Finding ways to translate this theoretical mandate into practice poses a number of particularly challenging socio-legal issues, which this research seeks to address. The English Mental Capacity Act 2005 (MCA sets out a right to support with decision-making (s.1(3, underpinned by a presumption of capacity (s.1(2. Qualitative interviews with intellectually disabled people, their supporters, and care and support professionals were undertaken to explore how disabled people make decisions in their everyday lives, the kinds of support they need, and the strategies for supported decision-making used in practice. Analysis of these interviews suggests that a range of supported decision-making techniques have been developed in practice and are effective in supporting everyday preferences and some life choices. Paradoxically, it appears that as decisions become more complex, the support available to disabled people reduces. Specifically, much less support is available for more difficult decisions around finances, healthcare and legal matters. We argue that the reasons for this are due to a web of regulatory, social and policy issues. We conclude that implementing the right to enjoy legal capacity through supported decision-making will require a combination of regulatory reform, social change and policy amendment.

    Physical rest after a concussion has been described as a key component in the management of the injury. Evidence supporting this recommendation, however, is limited. To examine the association between physical activity and symptom duration in a cohort of patients after a concussion. Cohort study; Level of evidence, 2. This study included 364 patients who were diagnosed with a concussion, were seen by a physician within 3 weeks of injury, and completed a questionnaire at the initial clinic visit. The questionnaire assessed the postconcussion symptom scale (PCSS) score, previous number of concussions, presence of the loss of consciousness or amnesia at the time of injury, and prior treatment for headaches. During each follow-up clinic visit, physical activity level was self-reported. A Cox proportional hazard model was constructed to determine the association between symptom duration, initial clinic visit responses, and self-reported physical activity level after the injury. Study participants ranged in age from 8 to 27 years (mean age, 15.0 years) and had sustained a mean of 0.8 prior concussions; 222 patients (61%) were male. On initial examination, the mean PCSS score was 34.7. The mean symptom duration was 48.9 days after the injury. Among the variables included in the model, initial PCSS score and female sex were independently associated with symptom duration, while physical activity level after the injury was not. For participants aged between 13 and 18 years, however, higher levels of physical activity after the injury were associated with a shorter symptom duration. Results from this study indicate that physical activity after the injury may not be universally detrimental to the recovery of concussion symptoms. © 2016 The Author(s).

    The New York City Department of Transportation (NYCDOT) has adopted strict containment and monitoring procedures during paint removal activities on its bridges because of the increasing awareness about lead poisoning in children in urban environments and the potential risk of lead-based paint releases during those activities. NYCDOT owns nearly 800 bridges scattered throughout New York City. Before undertaking paint removal activities as part of its ongoing preventive maintenance and rehabilitation program, NYCDOT recently conducted an analysis to determine the public health risk posed to children living near them. The analysis the first of its kind to assess the actual public health risk potential during both routine operations and upset conditions, or accidental releases evaluated the total and incremental blood lead levels from paint removal activities on more than 5,000 children from 6 months to 6 years old. Increases in baseline blood lead levels were estimated using several models, including EPA's Integrated Exposure Uptake Biokinetic (IEUBK) Model. This model estimates steady-state blood lead levels in children, reflecting exposure to lead in multiple media over an extended period of time. Increases in lead exposure from paint removal activities in the area surrounding the bridges was estimated using EPA's Industrial Source Complex (ISC3) model to calculate ambient air and deposition levels. Potential releases from the containment and ancillary equipment used in the paint removal process were modeled based on different release scenarios ranging from routine operations to complete failure of containment. To estimate the paint removal activities' contribution to long-term exterior dust lead levels (and its related interior component), a stochastic simulation model was developed for each block in the study area.

    Introduction Stroke is a leading health problem worldwide and an important cause of disability. Stroke survivors show low levels of physical activity, and increases in physical activity levels may improve function and health status. Therefore, the aims are to identify which interventions that have been employed to increase physical activity levels with stroke survivors, to verify their efficacy and to identify the gaps in the literature. Methods and analysis A systematic review of randomised controlled trials that investigated the efficacy of interventions aiming at increasing physical activity levels of stroke survivors will be conducted. Electronic searches will be performed in the MEDLINE, Physiotherapy Evidence Database (PEDro), Excerpta Medica (EMBASE), Literatura Latino-Americana e do Caribe em Ciências da Saúde (LILACS) and Scientific Electronic Library Online (SCIELO) databases. Hand searches of the reference lists of the included studies or relevant reviews will also be employed. Two independent reviewers will screen all the retrieved titles, abstracts and full texts. A third reviewer will be referred to solve any disagreements. The quality of the included studies will be assessed by the PEDro Rating Scale. This systematic review will also include a qualitative synthesis. Meta-analyses will be performed, if the studies are sufficiently homogeneous. This review will follow the Preferred Reporting Items for Systematic Review and Meta-Analysis (PRISMA) statement. The quality of the evidence regarding physical activity will be assessed, according to the Grading of Recommendations Assessment, Development and Evaluation (GRADE). Discussion This systematic review will provide information on which interventions are effective for increasing physical activity levels of stroke survivors. This evidence may be important for clinical decision-making and will allow the identification of gaps in the literature that may be useful for the definition of future research

    Full Text Available Optimizing physical activity during physical education is necessary for children to achieve daily physical activity recommendations. The purpose of this study was to examine the relationship among various contextual factors with accelerometer measured physical activity during elementary physical education. Data were collected during 2015–2016 from 281 students (1st–5th grade, 137 males, 144 females from a private school located in a metropolitan area of Utah in the U.S. Students wore accelerometers for 12 consecutive weeks at an accelerometer wear frequency of 3days per week during physical education. A multi-level general linear mixed effects model was employed to examine the relationship among various physical education contextual factors and percent of wear time in moderate-to-vigorous physical activity (%MVPA, accounting for clustering of observations within students and the clustering of students within classrooms. Explored contextual factors included grade level, lesson context, sex, and class size. Main effects and interactions among the factors were explored in the multi-level models. A two-way interaction of lesson context and class size on %MVPA was shown to be statistically significant. The greatest differences were found to be between fitness lessons using small class sizes compared to motor skill lessons using larger class sizes (β=14.8%, 95% C.I. 5.7%–23.9% p<0.001. Lessons that included a focus on fitness activities with class sizes that were <25 students associated with significantly higher %MVPA during elementary physical education.

    A growing body of evidence suggests that moderate to vigorous activity levels can affect quality of life, cognition, and brain structure in patients diagnosed with schizophrenia. However, physical activity has not been systematically studied during the period immediately preceding the onset of psychosis. Given reports of exercise-based neurogenesis in schizophrenia, understanding naturalistic physical activity levels in the prodrome may provide valuable information for early intervention efforts. The present study examined 29 ultra high-risk (UHR) and 27 matched controls to determine relationships between physical activity level, brain structure (hippocampus and parahippocampal gyrus), and symptoms. Participants were assessed with actigraphy for a 5-day period, MRI, and structured clinical interviews. UHR participants showed a greater percentage of time in sedentary behavior while healthy controls spent more time engaged in light to vigorous activity. There was a strong trend to suggest the UHR group showed less total physical activity. The UHR group exhibited smaller medial temporal volumes when compared with healthy controls. Total level of physical activity in the UHR group was moderately correlated with parahippocampal gyri bilaterally (right: r = .44, left: r = .55) and with occupational functioning (r = -.36; of negative symptom domain), but not positive symptomatology. Results suggest that inactivity is associated with medial temporal lobe health. Future studies are needed to determine if symptoms are driving inactivity, which in turn may be affecting the health of the parahippocampal structure and progression of illness. Although causality cannot be determined from the present design, these findings hold important implications for etiological conceptions and suggest promise for an experimental trial.

    To describe the functional status and self-rated health of patients with osteoarthritis (OA) in Primary Care, and checking their relationship with the level of physical activity and sociodemographic characteristics. Study of prevalence and cross association. Primary Care Clinics. Adult patients with a diagnosis of OA in any joint in their clinical records. Out of a total of 487 selected, 346 (71.0%) took part in the study. Functional capacity (WOMAC scale), self-rated quality of life (EuroQol- 5D questionnaire), physical activity (IPAQ questionnaire), number of affected joints, pain level, and sociodemographic characteristics. A mean score of 30.2 (SD: 20.8; CI 95% CI: 28.0 to 32.4) was obtained on the WOMAC scale, with pain, stiffness, and functional capacity scores of 6.5 (SD: 4.8), 1.9 (SD: 2.0), and 21.7 (SD: 15.7), respectively. The score showed a linear trend (P<.001) compared to the level of physical activity, being 41.1 (SD: 19.9) in inactive subjects, 24.3 (SD: 18.7) in subjects with moderate activity, and 22.3 (SD: 19.8) in subjects with intense activity. In the multiple linear regression, the score on the WOMAC scale, as well as that obtained in self-rated health status, maintained their association with physical activity level after adjusting for sociodemographic variables and the number of affected joints. In patients with OA, pain and functional capacity are the most affected dimensions. Functional status and self-rated health status are higher in active patients, regardless of the number of joints affected and their demographic characteristics.

    Full Text Available Levels of physical inactivity, a major contributor to burden of disease, are high in many countries. Some preliminary research suggests that circulating lutein concentrations are associated with high levels of physical activity (PA. We aimed to assess whether the intake of lutein-containing foods, including vegetables and eggs, is associated with levels of PA in two studies conducted in different countries. Dietary data and PA data collected from participants in two cross-sectional studies: the Maine-Syracuse Longitudinal Study (MSLS, conducted in Central New York, USA (n = 972, and the Observation of Cardiovascular Risk Factors in Luxembourg Study (ORISCAV-LUX (n = 1331 were analyzed. Higher intakes of lutein containing foods, including green leafy vegetables, were associated with higher levels of PA in both study sites. Increasing the consumption of lutein-rich foods may have the potential to impact positively on levels of PA. This needs to be further explored in randomized controlled trials.

    In order to alleviate the negative impacts of motorized vehicle use as well as create sustainable environment within campus area, it is pivotal to encourage mode shifting among university students. Active transport modes such as walking, cycling, and using public transport can be considered as alternative modes. This paper tried to identify the potential to increase active commuting in UGM by understanding student’s travel behavior. ANOVA test was employed to identify the perceptions between students across residential zones toward motivators and barriers to actively commute. The findings were used to propose strategies for increasing active commuting level in UGM, which are: reducing barriers to actively commute, improving public transport services, improving walking and cycling facilities, and introducing programs to discourage motorized vehicle use.

    The National Health and Morbidity Survey (NHMS, 2011), estimates that the number of Malaysian adults suffering from type 2 diabetes has increased from 8.3 to 31.2% since 1996. This study is a preliminary investigation of possible factors contributing to this epidemic. Knowledge of diabetes, health locus of control, diet and exercise habits, as well as family history, education level and other demographic factors to better understand the correlates of risky and healthy behaviors. This was done as part of a larger initiative to improve prevention efforts. Questionnaires were completed by 770 individuals from three Malaysian states: Selangor, Penang, and Terengganu. Findings showed that people with better health knowledge and those who have a family history of type 2 diabetes were more likely to have healthy diets. Also, health knowledge related to lower alcohol consumption. Participants with diabetic family members, however, also reported higher levels of stress. Counterintuitively, higher educational levels, higher internal locus of control, better health knowledge, as well as a family history of diabetes all correlated with lower levels of physical activity. Thus, it is suggested that, while increasing health knowledge will be important in addressing the type 2 diabetes epidemic in Malaysia, especially in relation to diet, other cultural factors, specifically norms related to exercise and physical activity, also need to be addressed if the spread of type 2 diabetes is to be addressed over the long term.

Findings showed that people with better health knowledge and those who have a family history of type 2 diabetes were more likely to have healthy diets. Also, health knowledge related to lower alcohol consumption. Participants with diabetic family members, however, also reported higher levels of stress. Counterintuitively, higher educational levels, higher internal locus of control, better health knowledge, as well as a family history of diabetes all correlated with lower levels of physical activity. Thus, it is suggested that, while increasing health knowledge will be important in addressing the type 2 diabetes epidemic in Malaysia, especially in relation to diet, other cultural factors, specifically norms related to exercise and physical activity, also need to be addressed if the spread of type 2 diabetes is to be addressed over the long term.

    Full Text Available The purpose of this study was to explore individual-level socio-demographic factors and interpersonal-level factors related to social support, as well as the potential role of neighborhood and school environments that may influence the physical activity (PA levels of children (ages 9–11. Child and parent questionnaires included individual and interpersonal factors, and PA behaviour. Home postal codes were used to determine the neighbourhood the child resides within, as well as their geographic accessibility to recreation opportunities. The models were assessed using a series of cross-classified random-intercept multi-level regression models as children’s PA may be affected by both the school they attend and the neighbourhood in which they live. In the unadjusted model, PA varied significantly across school environments (γ = 0.023; CI: 0.003–0.043, but not across neighbourhoods (γ = 0.007; CI: -0.008 to 0.021. Boys were found to be more active compared to girls (b = 0.183; CI: 0.092–0.275, while the level of PA was lower for children whose fathers achieved post-secondary education (b = - 0.197; CI: -0.376 to 0.018 than for those whose parents completed only high school. The addition of the individual-level correlates did not have a substantial effect on level 2 variances and the level 2 variance associated with school environment remained statistically significant. At the interpersonal level, children’s perception of parental support (b = 0.117; CI: 0.091–0.143 and peer support (b = 0.111; CI: 0.079–0.142 were positively related to PA. The level 2 variance for the school environment became statistically non-significant when the interpersonal factors were added to the model. At the environmental level, geographic accessibility did not have a significant association with PA and they did not significantly affect level 1 or 2 variance. As many children do not accrue sufficient levels of PA, identifying modifiable determinants is

    Full Text Available Cross-sectional studies have shown that objectively measured physical activity is associated with childhood adiposity, and a strong inverse dose-response association with body mass index (BMI has been found. However, few studies have explored the extent to which this association reflects reverse causation. We aimed to determine whether childhood adiposity causally influences levels of physical activity using genetic variants reliably associated with adiposity to estimate causal effects.The Avon Longitudinal Study of Parents and Children collected data on objectively assessed activity levels of 4,296 children at age 11 y with recorded BMI and genotypic data. We used 32 established genetic correlates of BMI combined in a weighted allelic score as an instrumental variable for adiposity to estimate the causal effect of adiposity on activity. In observational analysis, a 3.3 kg/m² (one standard deviation higher BMI was associated with 22.3 (95% CI, 17.0, 27.6 movement counts/min less total physical activity (p = 1.6×10⁻¹⁶, 2.6 (2.1, 3.1 min/d less moderate-to-vigorous-intensity activity (p = 3.7×10⁻²⁹, and 3.5 (1.5, 5.5 min/d more sedentary time (p = 5.0×10⁻⁴. In Mendelian randomization analyses, the same difference in BMI was associated with 32.4 (0.9, 63.9 movement counts/min less total physical activity (p = 0.04 (∼5.3% of the mean counts/minute, 2.8 (0.1, 5.5 min/d less moderate-to-vigorous-intensity activity (p = 0.04, and 13.2 (1.3, 25.2 min/d more sedentary time (p = 0.03. There was no strong evidence for a difference between variable estimates from observational estimates. Similar results were obtained using fat mass index. Low power and poor instrumentation of activity limited causal analysis of the influence of physical activity on BMI.Our results suggest that increased adiposity causes a reduction in physical activity in children and support research into the targeting of BMI in efforts to

    The Systems Biological Graphical Notation (SBGN) is an international community effort for standardized graphical representations of biological pathways and networks. The goal of SBGN is to provide unambiguous pathway and network maps for readers with different scientific backgrounds as well as to support efficient and accurate exchange of biological knowledge between different research communities, industry, and other players in systems biology. Three SBGN languages, Process Description (PD), Entity Relationship (ER) and Activity Flow (AF), allow for the representation of different aspects of biological and biochemical systems at different levels of detail. The SBGN Activity Flow language represents the influences of activities among various entities within a network. Unlike SBGN PD and ER that focus on the entities and their relationships with others, SBGN AF puts the emphasis on the functions (or activities) performed by the entities, and their effects to the functions of the same or other entities. The nodes (elements) describe the biological activities of the entities, such as protein kinase activity, binding activity or receptor activity, which can be easily mapped to Gene Ontology molecular function terms. The edges (connections) provide descriptions of relationships (or influences) between the activities, e.g., positive influence and negative influence. Among all three languages of SBGN, AF is the closest to signaling pathways in biological literature and textbooks, but its well-defined semantics offer a superior precision in expressing biological knowledge.

    Owing to an aging population and medical advances, the anticipated growth and prevalence of multimorbidity has been recognized as a significant challenge and priority in health care settings. Although physical activity has been shown to play a vital role in the primary and secondary prevention of chronic disease, much less is known about the relationship between physical activity and multimorbidity. The objective of the present study was to examine the relationship between physical activity levels and multimorbidity in male and female adults after adjusting for key demographic, geographical, and lifestyle factors. The study drew data from a prospective cohort in Atlantic Canada (2009-2015). The sample included 18,709 participants between the ages of 35-69. Eighteen chronic diseases were identified. Physical activity levels were estimated based on the long form of the International Physical Activity Questionnaire. Using logistic regression analysis, we found that multimorbid individuals were significantly more likely to be physically inactive (OR=1.26; 95% CI 1.10, 1.44) after adjusting for key sociodemographic and lifestyle characteristics. Additional stratified analyses suggest that the magnitude of the effect between multimorbidity and physical activity was stronger for men (OR=1.41; 95% CI 1.12, 1.79) than women (OR=1.18; CI 1.00, 1.39) and those living in rural (OR=1.43; CI 1.10, 1.85) versus urban (OR=1.20; CI 1.02, 141) areas. Given the generally low levels of physical activity across populations and a growing prevalence of multimorbidity, there is a need for a prospective study to explore causal associations between physical activity, multimorbidity, and health outcomes.

  18. Environmental noise levels affect the activity budget of the Florida manatee

    Manatees inhabit coastal bays, lagoons, and estuaries because they are dependent on the aquatic vegetation that grows in shallow waters. Food requirements force manatees to occupy the same areas in which human activities are the greatest. Noise produced from human activities has the potential to affect these animals by eliciting responses ranging from mild behavioral changes to extreme aversion. This study quantifies the behavioral responses of manatees to both changing levels of ambient noise and transient noise sources. Results indicate that elevated environmental noise levels do affect the overall activity budget of this species. The proportion of time manatees spend feeding, milling, and traveling in critical habitats changed as a function of noise level. More time was spent in the directed, goal-oriented behaviors of feeding and traveling, while less time was spent milling when noise levels were highest. The animals also responded to the transient noise of approaching vessels with changes in behavioral state and movements out of the geographical area. This suggests that manatees detect and respond to changes in environmental noise levels. Whether these changes legally constitute harassment and produce biologically significant effects need to be addressed with hypothesis-driven experiments and long-term monitoring.

    Full Text Available Introduction: The decline in physical activity levels of young children appears to be increased and combined with a high prevalence of obesity in Europe (Wang and Lim, 2012; Lobstein et al., 2004. With the ever-increasing interest in exploring the actual level of children’s physical activity in Albania, a study was carried out aiming to obtain the actual level on physical activity. Methods: A cross-sectional study was conducted on 9003 children aged 7-year-old to 15-year-old (4513 boys and 4490 girls. The PAQ-C questionnaire was validated in Albanian language and used to assess the current level of PA. Results: The results showed that 42.7% of children fell below the normal level of PA (inactivity. Data split by gender showed a higher percentage of inactivity among girls (49.6% compared to boys (36%. Finally, the results revealed a higher percentage of inactive children living in rural areas (49.2% compared to children in urban areas (45.4%. Discussion: In conclusion, the high percentage of inactive children poses a threat for increased obesity in Albanian children. Another concern emphasized the inactivity in rural areas due to the changes of their lifestyle and behavior. References: Lobstein T, Baur L, Uauy R and Isoiot (2004. Obes Rev, 5 (Suppl 1, 4–104.

    When patients start dialysis, their employment rate declines and disability benefits are an option. With patient sociodemographic and clinical characteristics including disability income status controlled, we investigated the significance of depressed mood and usual activity level as predictors of patients' continued employment after dialysis start. Incident patients from 296 randomly selected dialysis clinics were surveyed in the Comprehensive Dialysis Study (CDS). Participants provided information about employment status, disability income status, education, depressive symptoms measured by the Patient Health Questionnaire-2 (PHQ-2), and usual activity level/energy expenditure measured by the Human Activity Profile. Age, gender, race, insurance, diabetes, inability to ambulate or transfer, chronic obstructive pulmonary disease, cardiovascular conditions, and hemoglobin and serum albumin values at treatment start were obtained from US Renal Data System files. Dialysis modality was defined at time of interview. Among 585 CDS participants who worked in the previous year, 191 (32.6%) continued working after dialysis start. On the basis of the PHQ-2 cutoff score ≥3, 12.1% of patients who remained employed had possible or probable depression, compared with 32.8% of patients who were no longer employed. In adjusted analyses, higher Human Activity Profile scores were associated with increased likelihood of continued employment, and there was a borderline association between lower PHQ-2 scores and continued employment. Screening and management of depressive symptoms and support for increased activity level may facilitate patients' opportunity for continued employment after dialysis start, along with generally improving their overall quality of life.
