The focus of the PhenX (Phenotypes and eXposures) Toolkit is to provide researchers whose expertise lies outside a particular area with key measures identified by experts for uniform use in large-scale genetic studies and other extensive epidemiologic efforts going forward. The current paper specifically addresses the PhenX Toolkit research domain of physical activity and physical fitness (PA/PF), which are often associated with health outcomes. A Working Group (WG) of content experts completed a 6-month consensus process in which they identified a set of 14 high-priority, low-burden, and scientifically supported measures. During this process the WG considered self-reported and objective measures which included the latest technology (e.g., accelerometers, pedometers, heart-rate monitors). They also sought the input of measurement experts and other members of the research community during their deliberations. A majority of the measures include protocols for children (or adolescents), adults, and older adults or are applicable to all ages. Measures from the PA/PF domain and 20 other domains are publicly available and found at the PhenX Toolkit website, www.phenxtoolkit.org. The use of common measures and protocols across large studies enhances the capacity to combine or compare data across studies, benefitting both PA/PF experts and non-experts. Use of these common measures by the research community should increase statistical power and enhance the ability to answer scientific questions that might have previously gone unanswered.

Patients recovering after heart valve surgery are not in an optimum state of 'cardiorespiratory fitness'. To examine this proposition a controlled trial of physical training was undertaken in patients recovering from the replacement of a single heart valve. Patients were allocated to a test or control group two weeks after operation. Each patient performed a submaximal exercise test at entry, and twelve and twenty-four weeks after this test. The Canadian Air Force exercise programme was undertaken by the test group, while the control group continued normal activities for the twenty-four weeks between the first and last exercise test. A regression line of submaximal heart rate on oxygen consumption was calculated from the data of each exercise test in each patient. Alterations in this line were used as an 'index' of changes in 'cardiorespiratory fitness'. The individual results showed a consistent improvement in 'cardiorespiratory fitness' over the first 12 weeks in both groups. Only patients in the test group continued to improve between 12 and 24 weeks. Thus the exercise programme modified the recovery of 'cardiorespiratory fitness' after operation. A physical fitness rehabilitation programme may help these patients gain maximum benefit from correctiv surgery.

Cardiovascular disease is the most frequent cause of death, accounting for more than 30 % of all annual deaths. Elevated incidence of cardiovascular disease is seen among occupational groups exposed to high occupational physical activity, like cleaners. Conversely, moderate to high leisure time...... physical activity reduces risk factors for cardiovascular disease. However, it is not known whether this also holds for workers exposed to high occupational physical activity, or whether it will lead to a cardiovascular overload. The study therefore investigated whether an aerobic exercise worksite....... The effects were evaluated with objective physiological or diurnal data in an intention-to-treat analysis using multi-adjusted mixed models. The results indicated that the intervention led to several improvements in risk factors for cardiovascular disease, e.g. enhanced cardiorespiratory fitness, reduced...

Complex systems are characterized by specific time-dependent interactions among their many constituents. As a consequence they often manifest rich, non-trivial and unexpected behavior. Examples arise both in the physical and non-physical world. The study of complex systems forms a new interdisciplinary research area that cuts across physics, biology, ecology, economics, sociology, and the humanities. In this paper we review the essence of complex systems from a physicist's point of view, and try to clarify what makes them conceptually different from systems that are traditionally studied in physics. Our goal is to demonstrate how the dynamics of such systems may be conceptualized in quantitative and predictive terms by extending notions from statistical physics and how they can often be captured in a framework of co-evolving multiplex network structures. We mention three areas of complex-systems science that are currently studied extensively, the science of cities, dynamics of societies, and the representatio...

This is an introductory review of deterministic mutation-selection models for asexual populations (i.e., quasispecies theory) and related topics. First, the basic concepts of fitness, mutations, and sequence space are introduced. Different types of mutation-selection dynamics are defined and their relation to problems of statistical physics are outlined. Then the stationary population distribution in simple, single peak fitness landscapes is discussed at length, with particular emphasis on th...

We mention three areas of complex-systems science that are currently studied extensively, the science of cities, dynamics of societies, and the representation of texts as evolutionary objects. We discuss why these areas form complex systems in the above sense. We argue that there exists plenty of new ground for physicists to explore and that methodical and conceptual progress is needed most.

This paper provides observations of physical fitness testing in Texas schools and physical education teachers' insights about large-scale testing using the FITNESSGRAM assessment (Cooper Institute, 2007) as mandated by Texas Senate Bill 530. In the first study, undergraduate and graduate students who were trained to observe and assess student fitness testing in grades 3 through 12 provided observations. In the second study, physical education teachers responded to selected interview questions during a focus group discussion. From the observations and responses, specific themes emerged related to teachers' knowledge and training about conducting fitness testing and managing data, students' knowledge and motivation, support and resources for conducting fitness assessments, and complexity of the fitness situation.

The U.S. Army Physical Fitness School (USAPFS) at Ft. Benjamin Harrison, IN was tasked with measuring the physical fitness of the active Army. Performance on the Army Physical Fitness Test (APFT) was used to determine fitness levels. Data were collected at 14 U.S. Army installations CONUS-wide between October 1 and November 30, 1988. Five thousand three hundred forty-six male and 676 female active Army soldiers (N = 6.022) between the ages of 17-52 and in 60 military occupational specialties (MOSs) participated in the study. Generally, the results were favorable. Senior age groups performed well overall, especially females. Improvement in muscular strength and endurance conditioning since 1984 was also observed. However, concern was raised about poor performance in the youngest age group (17-21), where 16.6% of the males failed the 2-mile run event and 29.0% failed overall. Likewise, for females in the 17-21 year age group, 28.8% failed the 2-mile run and 36.0% failed overall. Several reasons are suggested for the poor performance of the younger age groups, including inadequate leadership in fitness training and low levels of self-motivation. This study suggest that many soldiers, especially young soldiers, may not possess sufficient levels of physical fitness to meet the physical demands of war.

Full Text Available The two main goals of this review were to understand how the relationships between physical activity, physical fitness, somatic fitness, and coordination are established along the motor development of children and adolescents, and how they would influence their future lives. The web based bibliographic database B-On was searched for peer-reviewed publications during the last decade (2000 to 2009. Search criteria included all articles on relationships between any two of the above named factors. Although different methodological designs and variables were found as markers for the same factor, overall results suggested the existence of a clear positive relationship among physical activity, physical fitness, somatic fitness, and coordination from childhood to adolescence, with a special relevance for the relationship between physical activity and coordination. It was also noted a renewed interest on physical activity and motor coordination developmental characteristics and relationships as well as on their lifelong health effects.

This study aimed to investigate longitudinal associations of objectively measured physical activity (PA) and sedentary behavior (SB) with body composition and physical fitness at a 12-month follow-up in healthy Swedish 4-yr-old children. The data from the population-based MINISTOP trial were collected between 2014 and 2016, and this study included the 138 children who were in the control group. PA and SB were assessed using the wrist-worn ActiGraph (wGT3x-BT) accelerometer during seven 24-h periods and, subsequently, defined as SB, light-intensity PA, moderate-intensity PA, vigorous-intensity PA (VPA), and moderate-to-vigorous PA (MVPA). Body composition was measured using air-displacement plethysmography and physical fitness (cardiorespiratory fitness, lower and upper muscular strength as well as motor fitness) by the PREFIT fitness battery. Linear regression and isotemporal substitution models were applied. Greater VPA and MVPA at the age of 4.5 yr were associated with higher fat-free mass index (FFMI) at 5.5 yr (P fitness, lower body muscular strength, and motor fitness at 12-month follow-up (P = 0.001 to P = 0.031). Substituting 5 min·d of SB, light-intensity PA, or moderate-intensity PA for VPA at the age of 4.5 yr were associated with higher FFMI, and with greater upper and lower muscular strength at 12-month follow-up (P fitness at 12-month follow-up. Our results indicate that promoting high-intensity PA at young ages may have long-term beneficial effects on childhood body composition and physical fitness, in particular muscular strength.

One role of Army Reserved Officer's Training Corps (ROTC) programs is to physically prepare cadets for the demands of a military career. Cadets participate in physical training 3 days per week as part of their military science curriculum. Limited research has been conducted on the fitness level of ROTC cadets; therefore, the purpose of this study was to profile the physical fitness status of a cadre of ROTC cadets. Forty-three cadets (30 men and 13 women) performed Army Physical Fitness Test (APFT) assessments (2-mile run, 2-minute maximum push-ups and sit-ups) and clinical assessments of fitness (Bruce protocol Vo(2)max, underwater weighing, and 1 repetition maximum [1RM] bench press tests). Mean +/- standard deviations were calculated to provide the physical fitness profile for each parameter. Male cadets (21 +/- 2.2 years; height 177.4 +/- 6.6 cm; mass 79.2 +/- 9.4 kg) scored 49.6 +/- 6.1 ml.kg(-1).min(-1) for Vo(2)max, 14.8 +/- 4.2% fat, 86.5 +/- 24.9 kg 1RM bench press, 2-mile run of 13.97 +/- 1.4 minutes, 70.5 +/- 12.8 sit-ups, and 60.2 +/- 13.2 push-ups. Female cadets (20 +/- 2.4 years; height 165.1 +/- 8.0 cm; mass 63.5 +/- 10.0 kg) scored 40.8 +/- 3.9 ml.kg(-1).min(-1) for Vo(2) max, 23.9 +/- 3.8% fat, 35.3 +/- 8.2 kg 1RM bench press, 2-mile run of 17.0 +/- 1.6 minutes, 65.0 +/- 12.9 sit-ups, and 33.3 +/- 11.2 push-ups. The mean scores were above the 83rd percentile on all APFT items and average (percent fat) to above average (Vo(2)max and men's bench press scores) when compared with peer-age and sex-corrected norms. Only the women's bench press score was below average. With the exception of the women's bench press, these ROTC cadets possessed average to above average levels of fitness.

Full Text Available This study examined the extent to which four essential dimensions of quality physical education teaching (QPET were associated with healthy levels of physical fitness in elementary school students. Participants were nine elementary PE teachers and 1, 201 fourth- and fifth-grade students who were enrolled in nine elementary schools. The students’ physical fitness were assessed using four FITNESSGRAM tests. The PE teachers’ levels of QPET were assessed using the Assessing Quality Teaching Rubrics (AQTR. The AQTR consisted of four essential dimensions including Task Design, Task Presentation, Class Management, and Instructional Guidance. Codes were confirmed through inter-rater reliability (82.4% and 84.5%. Data were analyzed through descriptive statistics, multiple R-squared regression models, and independent sample t-tests. The four essential teaching dimensions of QPET were significantly associated with the students’ cardiovascular endurance, muscular strength and endurance, and flexibility. However, they accounted for relatively low percentage of the total variance in PACER test, followed by Curl-up test, while explaining very low portions of the total variance in Push-up and Trunk Lift tests. This study indicated that the students who had experienced high level of QPET were more physically fit than their peers who did not have this experience in PACER and Curl-up tests, but not in Push-up and Trunk lift tests. In addition, the significant contribution of the four essential teaching dimensions to physical fitness components was gender-specific. It was concluded that the four teaching dimensions of QPET were significantly associated with students’ health-enhancing physical fitness.

The purpose of this study was to assess the short-term effect of a physical fitness program on physical self-concept and physical fitness elements among primary school students. Spanish boys and girls (N = 75; M age = 11.1 yr., SD = 0.4) were divided into an experimental group and a control group. During physical education classes, the experimental group performed an 8-week program including two circuits of 8 exercises done for 15 to 35 sec. each with 45 to 25 sec. of rest between them. Physical self-concept (Physical Self-Description Questionnaire) and physical fitness (EUROFIT battery tests) were measured at the beginning and at the end of the physical fitness program. The results showed that the improvements in physical fitness were not accompanied by major changes in physical self-concept, even though the physical fitness program seemed to maintain the Experimental group's previous physical appearance, strength, and self-esteem perceptions, all of which statistically significantly decreased in the control group after the intervention.

Levels of physical fitness are low after stroke. It is unknown whether improving physical fitness after stroke reduces disability. To determine whether fitness training after stroke reduces death, dependence, and disability. The secondary aims were to determine the effects of training on physical fitness, mobility, physical function, quality of life, mood, and incidence of adverse events. We searched the Cochrane Stroke Group Trials Register (last searched April 2010), the Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library, July 2010), MEDLINE (1966 to March 2010), EMBASE (1980 to March 2010), CINAHL (1982 to March 2010), SPORTDiscus (1949 to March 2010), and five additional databases (March 2010). We also searched ongoing trials registers, handsearched relevant journals and conference proceedings, screened reference lists, and contacted experts in the field. Randomised trials comparing either cardiorespiratory training or resistance training, or both, with no intervention, a non-exercise intervention, or usual care in stroke survivors. Two review authors independently selected trials, assessed quality, and extracted data. We analysed data using random-effects meta-analyses. Diverse outcome measures limited the intended analyses. We included 32 trials, involving 1414 participants, which comprised cardiorespiratory (14 trials, 651 participants), resistance (seven trials, 246 participants), and mixed training interventions (11 trials, 517 participants). Five deaths were reported at the end of the intervention and nine at the end of follow-up. No dependence data were reported. Diverse outcome measures made data pooling difficult. The majority of the estimates of effect were not significant. Cardiorespiratory training involving walking improved maximum walking speed (mean difference (MD) 8.66 metres per minute, 95% confidence interval (CI) 2.98 to 14.34), preferred gait speed (MD 4.68 metres per minute, 95% CI 1.40 to 7.96) and walking

In Volume 1 of Pediatric Exercise Science (PES), a paper by Fenster et al. (25) investigated the relationship between peak oxygen uptake (peak VO2) and physical activity (PA) in 6- to 8-year-old children. They used both questionnaires and large-scale integrated activity monitors (LSIs) to estimate daily PA and determined peak VO2 using an incremental treadmill test to volitional exhaustion. They concluded that peak VO2 correlated well with PA as measured by LSIs but commented that questionnaire data were only weakly and nonsignificantly associated with LSI and peak VO2 data. Peak VO2 and PA are the most researched and reported variables in the 25-year history of PES. Yet, the assessment and interpretation of young people's aerobic fitness and PA remain problematic and any meaningful relationship between them during childhood and adolescence is shrouded with controversy. The present paper uses Fenster et al.'s (25) report as an indicator of where we were 25 years ago, outlines how far we have advanced since then, and suggests future directions of research in the study of aerobic fitness and PA. In the first volume of PES, Fenster, Freedson, Washburn, and Ellison (25) investigated the relationship between 6- to 8-year-old children's peak oxygen uptake (peak VO2) and physical activity (PA). Five boys and 13 girls participated in the study and their data were pooled for analysis. Peak VO2 was determined during an incremental treadmill test to voluntary exhaustion and PA was estimated using both questionnaires and large-scale integrated activity monitors (LSIs). On the basis of a significant interclass correlation coefficient of r = .59 between peak VO2 and the log of LSI average counts per hour Fenster et al. (25) concluded that "aerobic capacity, as measured by peak VO2 correlated well with physical activity as measured by LSI" (p.134). They also commented that questionnaire data were only weakly and nonsignificantly associated with LSI and peak VO2 data. Young people

Full Text Available In addition to traditional forms of daily physical exercise, different types of physical exercises appeared, which are quite interesting and more appealing than the usual forms of exercise. Aerobic dance is one of those types of physical exercise that can positively influence the development of some of the components of physical fitness. The aim of this study was to examine the scientific research concerning the effects of aerobic dance on physical fitness with people aged 20 to 39. The conclusion is that aerobic dance can contribute to the improvement of certain components of physical fitness and that the greatest impact aerobic dance has on the cardiovascular system and body composition

The aim of this study was to analyze the relationship between creativity and physical fitness in elementary school children. Data were collected from 308 primary school students in southern Spain, ranging in age from 8 to 12 years (mean, 9.72 ± 1.25 years). They completed a fitness test battery, and the Prueba de Imaginación Creativa para Niños (PIC-N; Creative Imagination Test for Children) to analyze creativity. Significant differences were found between the sexes. Boys had better physical fitness but there were no sex differences in creativity. On clusters analysis, the highly creative groups had better physical fitness. Creativity was correlated with physical fitness. Aerobic capacity was a predictor of creativity. There is an association between creativity and physical fitness in primary school children that may have important implications for academic achievement. © 2017 Japan Pediatric Society.

Full Text Available Previous research has suggested a positive effect of physical activity on life satisfaction. Little research exists that has investigated the relationship between physical fitness and life satisfaction. For this purpose, this research was done to determine the relationship between physical fitness and life satisfaction in a sample of university men and women. Participants (N = 28, Mage = 22.18 completed multiple indicators of physical fitness including cardiovascular fitness, muscular fitness, body composition and flexibility, and life satisfaction (SWLS. Descriptive and one-way between-groups ANOVAs were performed to determine gender differences on measures of life satisfaction and measures of fitness. In addition, the relationship between the five health-related components of fitness and life satisfaction were investigated using Pearson’s product–moment correlation coefficient. Analyses indicated there were no significant correlations between any of the health-related components of fitness and scores on the SWLS. There were significant gender differences on all physical fitness measures, except partial curl-ups, but no significant gender differences on life satisfaction. Our findings suggest that improved physical fitness does not have a relationship with higher life satisfaction measures. Further tests, utilizing larger sample sizes, are recommended.

Mental health-related problems are a significant cause of attrition during basic combat training (BCT). Evidence in civilian populations suggests that physical fitness is associated with psychological benefits in civilians, but little is known about the association between physical fitness and psychological adjustment during BCT. This study prospectively examined the association between physical fitness and depressive symptoms in 300 BCT soldiers from May to July 2012 at Fort Jackson, Columbia, SC. Soldiers completed a baseline Army Physical Fitness Test (APFT) and survey within 1 wk of arriving at BCT and an end-of-cycle survey after 8 wk of BCT. Soldiers were assigned to the "high" fitness category if they had a passing score on the standard APFT of greater than or equal to 180 out of 300 points. Soldiers scoring less than 180 points on the APFT were assigned to the "low" fitness category. Depressive symptoms were measured using the 20-item Center for Epidemiologic Studies Depression scale. In multivariate analyses, adjusting for baseline demographics, self-reported sleep before BCT, BCT confidence, Army identification, and depressive symptoms, the odds of reporting depressive symptoms were 60% lower for soldiers in the high fitness category (odds ratio, 0.40; 95% confidence interval, 0.19-0.84) compared with soldiers in the low fitness category. Analogous to other positive outcomes of soldier fitness, improvement of soldier physical fitness before BCT might improve soldiers' psychological health outcomes.

Low levels of physical activity are a global health concern for all children. Children with cerebral palsy have even lower physical activity levels than their typically developing peers. Low levels of physical activity, and thus an increased risk for related chronic diseases, are associated with deficits in health-related physical fitness. Recent research has provided therapists with the resources to effectively perform physical fitness testing and physical activity training in clinical settings with children who have cerebral palsy, although most testing and training data to date pertains to those who walk. Nevertheless, based on the present evidence, all children with cerebral palsy should engage, to the extent they are able, in aerobic, anaerobic and muscle strengthening activities. Future research is required to determine the best ways to evaluate health-related physical fitness in non-ambulatory children with cerebral palsy and foster long-term changes in physical activity behavior in all children with this condition.

This study compared the physical fitness of 28 visually impaired goalball players (M=13 yr.) and a group of 27 less active age-matched adolescents. Physical characteristics (age, height, weight, sex) and visual acuity of the children were recorded. Body composition (Body Mass Index, skinfold thickness of triceps plus calf), musculoskeletal function (trunk-lift, curl-up, isometric push-up, shoulder-stretch tests) and aerobic function (1-mile run/walk test) were evaluated according to the Brockport Physical Fitness Test Battery. Also, anaerobic power was assessed by a vertical jump test. Physical fitness of visually impaired goalball players was higher than that of the more sedentary group (p.05). It was considered that directing visually impaired children to participation sports or recreational activities such as goalball has importance in improving their physical fitness.

Although fitness landscapes are central to evolutionary theory, so far no biologically realistic examples for large-scale fitness landscapes have been described. Most currently available biological examples are restricted to very few loci or alleles and therefore do not capture the high dimensionality characteristic of real fitness landscapes. Here we analyze large-scale fitness landscapes that are based on predictive models for in vitro replicative fitness of HIV-1. We find that these landscapes are characterized by large correlation lengths, considerable neutrality, and high ruggedness and that these properties depend only weakly on whether fitness is measured in the absence or presence of different antiretrovirals. Accordingly, adaptive processes on these landscapes depend sensitively on the initial conditions. While the relative extent to which mutations affect fitness on their own (main effects) or in combination with other mutations (epistasis) is a strong determinant of these properties, the fitness landscape of HIV-1 is considerably less rugged, less neutral, and more correlated than expected from the distribution of main effects and epistatic interactions alone. Overall this study confirms theoretical conjectures about the complexity of biological fitness landscapes and the importance of the high dimensionality of the genetic space in which adaptation takes place.

A few studies have recently reported that higher cardiorespiratory fitness is associated with higher volumes of subcortical brain structures in children. It is, however, unknown how different fitness measures relate to shapes of subcortical brain nuclei. We aimed to examine the association of the main health-related physical fitness components with shapes of subcortical brain structures in a sample of forty-four Spanish children aged 9·7 (sd 0·2) years from the NUtraceuticals for a HEALthier life project. Cardiorespiratory fitness, muscular strength and speed agility were assessed using valid and reliable tests (ALPHA-fitness test battery). Shape of the subcortical brain structures was assessed by MRI, and its relationship with fitness was examined after controlling for a set of potential confounders using a partial correlation permutation approach. Our results showed that all physical fitness components studied were significantly related to the shapes of subcortical brain nuclei. These associations were both positive and negative, indicating that a higher level of fitness in childhood is related to both expansions and contractions in certain regions of the accumbens, amygdala, caudate, hippocampus, pallidum, putamen and thalamus. Cardiorespiratory fitness was mainly associated with expansions, whereas handgrip was mostly associated with contractions in the structures studied. Future randomised-controlled trials will confirm or contrast our findings, demonstrating whether changes in fitness modify the shapes of brain structures and the extent to which those changes influence cognitive function.

This case study was done to determine whether physical fitness plays a part in performing flute repertoire. Most repertoire allows performers the choice of where to breathe. However, there exists a "brute" repertoire where breathing is prescribed by the composer, which poses physical challenges for performers. The author contrasted pieces from traditional repertoire with Heinz Holliger's (t)air(e), which requires passages of breath-holding and measured inhalations. The author was tested for cardiovascular fitness (VO2max) and corresponded these levels to pulse rates while playing at baseline and 6 months after undertaking a physical fitness program. After the exercise program, expertise with standard repertoire combined with the unmeasured variables of resonance, openness of the chest and oral cavities, embouchure size, and air speed saw little improvement with increased fitness levels. However, when air regulation is out of the performer's control, the effect of cardiovascular training brought the "brute" repertoire into the same range of difficulty as the standard repertoire.

We argue that complex systems science and the rules of quantum physics are intricately related. We discuss a range of quantum phenomena, such as cryptography, computation and quantum phases, and the rules responsible for their complexity. We identify correlations as a central concept connecting quantum information and complex systems science. We present two examples for the power of correlations: using quantum resources to simulate the correlations of a stochastic process and to implement a classically impossible computational task.

The aim was to investigate whether there was an association between amino acid (AA) intake and physical fitness and if so, to assess whether this association was independent of carbohydrates intake. European adolescents (n = 1481, 12.5-17.5 years) were measured. Intake was assessed via two non-consecutive 24-h dietary recalls. Lower and upper limbs muscular fitness was assessed by standing long jump and handgrip strength tests, respectively. Cardiorespiratory fitness was assessed by the 20-m shuttle run test. Physical activity was objectively measured. Socioeconomic status was obtained via questionnaires. Lower limbs muscular fitness seems to be positively associated with tryptophan, histidine and methionine intake in boys, regardless of centre, age, socioeconomic status, physical activity and total energy intake (model 1). However, these associations disappeared once carbohydrates intake was controlled for (model 2). In girls, only proline intake seems to be positively associated with lower limbs muscular fitness (model 2) while cardiorespiratory fitness seems to be positively associated with leucine (model 1) and proline intake (models 1 and 2). None of the observed significant associations remained significant once multiple testing was controlled for. In conclusion, we failed to detect any associations between any of the evaluated AAs and physical fitness after taking into account the effect of multiple testing.

childhood. Special emphasis was placed on physical activity and a description of spa therapy for obese children in Spa Bludov which incorporated a plan of physical activity, diet and psychological therapy. Additionally the study set out to evaluate the actual muscular and physical fitness of obese children and determine the effect of one month spa therapy on muscular fitness and general physical fitness in obese children. This study included one group of 26 obese children who had complex spa therapy and one control group of non obese children. Before and after one month spa therapy measurements of muscular fitness and general physical fitness of obese children were taken utilising the Kraus-Weber test of minimal muscular fitness and a test of general physical fitness. Outcomes for both groups were compared. It emerged that complex spa therapy has a considerable influence on physical fitness in obese children.

Physical activity and physical fitness are important for health, functional mobility and performance of everyday activities. To date, little attention has been given to physical activity and physical fitness among nursing home residents with cognitive impairment. Therefore, the main aim of this study was to examine physical activity behavior and physical fitness of institutionalized older adults with cognitive impairment and to investigate their interrelations. Forty-eight older adults with cognitive impairment (83.9±7.7years; 72.9% women) and 22 without cognitive impairment (82.2±8.8years; 54.5% women) participated. Physical activity was objectively assessed with accelerometers and physical fitness components (muscular strength, flexibility, balance, body composition and reaction time) were evaluated with physical fitness field tests. Nursing home residents with cognitive impairment spent only ~1min per day in moderate physical activity and ~89min in light physical activity. In average they accumulated 863 (±599) steps per day and spent 87.2% of the accelerometer wear time in sedentary behavior. Participants' physical fitness components were markedly low and according to the cut-offs used for interpreting the results a great number of nursing home residents had an increased risk of associated health problems, functional impairment and of falling. The performance in some physical fitness tests was positively associated with physical activity. Participants without cognitive impairment had higher levels of physical activity and physical fitness than their counterparts with cognitive impairment. These results indicate that nursing home residents, especially those with cognitive impairment, have low levels of physical activity, spent a high proportion of daytime in sedentary behavior and have low physical fitness. Nursing homes should implement health promotion strategies targeting physical activity and physical fitness of their residents. Copyright © 2017 Elsevier
Full Text Available Introduction. Together with longer human lives, increase in economy level and higher social expectations, there is also need for developing science studies on physical culture and its role in prevention of ageing. Taking care of physical fitness is one of the main factor that guarantees both health and high quality life for millions of older people. The purpose of this article was to determine the changes of physical fitness level under the influence of Nordic walking trainingin women aged 60-75 years. Material and methods. 65 women aged 60-75 years were the subject of this study. Women were divided into 2 groups: control group (26 people and experimental group (39 people. Women from experimental group were taking part in Nordic walking training for 15 weeks, 2 times a week, 60 minutes each meeting. To determine the level of physical fitness some trials from EUROFIT test for adults were applied and march test 2 km was held. Results. The trend of improvement of physical fitness under health education and Nordic walking training was determined. The best results was on endurance field (statistically significant p<0.05. It was also observed slight decrease in physical fitness in women that didn't take part in mentioned training.

Fighting childhood obesity has become a key policy focus. The role of community-based interventions to promote physical activity is an important part of an overall strategy to increase physical activity for youth. This study examines whether community-based afterschool physical activity programs lead to improved youth fitness and lower obesity rates. Individually linked, longitudinal administrative data were used from local afterschool programs and two school districts in one California community to follow 1105 students from the 2006-2007 to 2008-2009 school years. Models were estimated in 2009-2010 using linear probability regressions and robust SEs, controlling for individual, family, and school characteristics, including fitness and overweight status prior to program participation. One third (36%) of the students participated in fitness-focused afterschool programs. Controlling for baseline fitness status, participating in fitness-focused afterschool programs was associated with a 10% increase in the probability of being physically fit after 2 years. This finding held for nearly all subgroups, including students who were initially unfit. Participation in 2 years of the program was associated with a 14.7% increased likelihood of subsequent fitness compared to 8.8% for 1 year of participation. Participation in other types of afterschool programs was not associated with fitness improvements. There were no effects of participation in either type of program on overweight status. These findings point to the promise of relying on existing community resources in the fight against childhood obesity. Fitness-focused afterschool programs will need to ensure that the highest-risk children--including those who are Latino and low-income--are served.

Despite numerous health benefits, less than half of American adults engage in regular physical activity. Exercise videogames (EVG) may be a practical and attractive alternative to traditional forms of exercise. However there is insufficient research to determine whether EVG play alone is sufficient to produce prolonged engagement in physical activity or improvements in cardiovascular fitness and overall health risk. The goal of the present study is to test the efficacy of exercise videogames to increase time spent in moderate to vigorous physical activity (MVPA) and to improve cardiovascular risk indices among adults. Wii Heart Fitness is a rigorous 3-arm randomized controlled trial with adults comparing three 12-week programs: (1) supervised EVGs, (2) supervised standard exercise, and (3) a control condition. Heart rate is monitored continuously throughout all exercise sessions. Assessments are conducted at baseline, end of intervention (week 12), 6 and 9 months. The primary outcome is time spent in MVPA physical activity. Secondary outcomes include changes in cardiovascular fitness, body composition, blood lipid profiles and maintenance of physical activity through six months post-treatment. Changes in cognitive and affective constructs derived from Self Determination and Social Cognitive Theories will be examined to explain the differential outcomes between the two active treatment conditions. The Wii Heart Fitness study is designed to test whether regular participation in EVGs can be an adequate source of physical activity for adults. This study will produce new data on the effect of EVGs on cardiovascular fitness indices and prolonged engagement with physical activity. Copyright © 2015 Elsevier Inc. All rights reserved.

A system is loosely defined as complex if it is composed of a large number of elements, interacting with each other, and the emergent global dynamics is qualitatively different from the dynamics of each one of the parts. The global dynamics may be either ordered or chaotic and among the most interesting emergent global properties are those of learning and adaptation.Complex systems, in the above sense, appear in many fields ranging from physics and technology to life and social sciences. Research in complex systems involves therefore a wide range of topics, studied in seemingly disparate field

This study aimed to assess the effect of the HEALTHY intervention on the metabolic syndrome (Met-S), fitness, and physical activity levels of US middle-school students. Cluster randomized controlled trial conducted in 42 (21 intervention) US middle schools. Participants were recruited at the start of sixth grade (2006) when baseline assessments were made, with post-assessments made 2.5 yr later at the end of eighth grade (2009). The HEALTHY intervention had four components: 1) improved school food environment, 2) physical activity and eating educational sessions, 3) social marketing, and 4) revised physical education curriculum. Met-S risk factors, 20-m shuttle run (fitness), and self-reported moderate to vigorous physical activity (MVPA) were assessed at each time point. Ethnicity and gender were self-reported. Obesity status (normal weight, overweight, or obese) was also assessed. At baseline, 5% of the participants were classified with Met-S, with two-thirds of the males and one-third of the females recording below average baseline fitness levels. Control group participants reported 96 min of MVPA at baseline with 103 min reported by the intervention group. There were no statistically significant (P physical activity levels. Approaches that focus on how to change physical activity, fitness, and Met-S using nonschool or perhaps in addition to school based components need to be developed.

This cross-sectional study examined factors related to children's physical fitness and activity levels in Taiwan. A total of 331 Taiwanese children, aged 7 and 8, and their mothers participated in the study. Children performed physical fitness tests, recorded their physical activities during two weekdays and completed self-esteem questionnaires. Research assistants measured the children's body mass and stature. Mothers completed demographic, parenting style and physical activity questionnaires. Attending urban school, lower body mass index (BMI), older age and better muscular endurance contributed to the variance in better aerobic capacity, and attending rural school and better aerobic capacity contributed to the variance in better muscular endurance in boys. Attending urban school, lower BMI and better athletic competence contributed to the variance in better aerobic capacity, and younger age, rural school and higher household income contributed to the variance in better flexibility in girls. Despite the limitations of the study, with many countries and regions, including Taiwan, now emphasizing the importance of improving physical fitness and activity in children, an intervention that is gender-, geographically, and developmentally appropriate can improve the likelihood of successful physical fitness and activity programmes.
Full Text Available The purpose of this study was to determine the relationship between physical fitness and levels of depression in older persons involved in physical activity programs in San Ramon, Alajuela. A total of 138 older adults aged 60 to 86 years (67.94 ± 5.26 were assessed on the physical fitness using the SFT and levels of depression were measured using the GDS. Results suggest that about 97.8% of persons tested were within normal parameters and excellent on their physical fitness. Additionally, 86.2% of the cohort was found in a normal stage of depression. In addition, geriatric depression was negatively correlated with physical fitness on variables such as lower body muscle strength and endurance, arm muscle strength endurance, physical agility and dynamic balance, and lower body flexibility (p<0.05. It is concluded that higher levels of physical fitness are associated with lower depression status in older adults.

Low levels of physical activity are a global health concern for all children. Children with cerebral palsy have even lower physical activity levels than their typically developing peers. Low levels of physical activity, and thus an increased risk for related chronic diseases, are associated with deficits in health-related physical fitness. Recent research has provided therapists with the resources to effectively perform physical fitness testing and physical activity training in clinical settings with children who have cerebral palsy, although most testing and training data to date pertains to those who walk. Nevertheless, on the basis of the present evidence, all children with cerebral palsy should engage, to the extent they are able, in aerobic, anaerobic, and muscle-strengthening activities. Future research is required to determine the best ways to evaluate health-related physical fitness in nonambulatory children with cerebral palsy and foster long-term changes in physical activity behavior in all children with this condition. © The Author(s) 2014.

The aim of this study was to establish sex- and age-specific physical fitness percentiles in French youth. A sample of 11,186 children and adolescents (5,546 boys and 5,640 girls), aged between 10 and 15 years, was assessed in the French national BOUGE study. Participants were tested for their cardiorespiratory fitness, muscular endurance, speed, flexibility, and agility using the following tests: 20-m shuttle run tests, curl-ups test, 50-m sprint test, back-saver sit and reach test, and 10 × 5-m shuttle run test. Percentile values were estimated for French youth as a function of age stratified by sex using the generalized additive model for location, scale, and shape (GAMLSS). In general, physical fitness was better in boys than in girls, except for the back-saver sit and reach test, in which girls performed better. Except for the back-saver sit and reach test and 10 × 5-m shuttle run test, physical fitness performance was significantly associated with age. Sex- and age-specific normative values for physical fitness tests in French youth expressed as percentiles from the fifth to the 95th are provided. Reference values provide normative data for French youth. The data are useful in identifying special needs for appropriate intervention programs.

Abstract This study examines the relationship between habitual dietary practices and performance on the physical readiness test required of active duty Navy personnel. Participants were 1,013 men (mean age = 26.2 years) stationed aboard nine Navy ships. The men completed a self-report survey of lifestyle and dietary habits and were evaluated on four tests of physical fitness: 1.5-mile Run, Sit-ups, Sit-reach, and Percent Body Fat. A standardized Overall Fitness score was also computed for each person. Results indicated that the participants tended to skip breakfast, ingest moderate amounts of caffeine, and favor a high-fat, low-fiber diet. Fitness scores were associated with a number of dietary variables, including caffeine intake, between-meal snacking, and overeating (all negatively related to fitness, p <.01), and having a general "nutrition orientation" (positively related to fitness, p <.001). The relationships were confounded by the influence of age, exercise, and smoking, but even after controlling for these, diet was a significant predictor of fitness (p <.001).

To examine the association of physical fitness and obesity with academic achievement and the independent association between fitness and academic achievement after controlling for relevant confounders such as age, parental education, and body mass index in school aged children. Cross-sectional study including 893 schoolchildren, aged 9-11 years, from Cuenca, Spain. Data were collected from September to November 2010. We measured academic achievement (mean of the grades obtained in several core subjects), physical fitness (cardio-respiratory fitness, muscular fitness, and speed/agility), weight, height, and parental education. Multivariate logistic regression models were used to estimate the probability of being in high quartiles for academic achievement after controlling for potential confounders. Overall, academic achievement scores were positively related to fitness levels. Obese boys had lower scores for academic achievement than overweight or normal weight boys. Good cardio-respiratory and speed/agility levels were associated with high academic achievement after controlling for confounders (OR 3.06; 95% CI, 1.35-6.91; P = .007 and OR 4.25; 95% CI, 1.91-9.44; P academic achievement.

Injuries are the leading cause of medical encounters across the U.S. military services resulting in more than 2.0 million clinic visits per year. Almost 50% of military service members experience an injury each year and half of those injuries are caused by physical training (PT), exercise, or sports. To prevent a problem as large and complex as injuries in the military requires a systematic approach. Several key questions must be answered to effectively address a problem such as injuries: (1) how big is the problem? (2) what are the causes and risk factors for the problem? (3) do modifiable risk factors for the problem exist? and (4) what works to prevent the problem? The article discusses leading causes of injuries for U.S. Army populations. It then explores key risk factors for exercise and training-related injuries: (1) the amounts of training, (2) types of training activities, (3) participants level of fitness, and (4) personal health risk behaviors. The article concludes with a review of prevention strategies illustrating interventions that have been shown to be effective, and others that are not effective. The data presented suggest that PT and exercise cause injuries and that modifications of training are most likely to prevent the problem.

Physical activity and fitness play a significant role in prevention of overweight and obesity in children and adolescents. Current understanding and evidence from epidemiologic studies provide useful insights to better understand how they relate to each other and how to develop future intervention strategies. This paper summarizes the most relevant information from cross-sectional and longitudinal studies on the relationships between physical activity, physical fitness, and overweight in early life. According to current scientific evidence: (i) High levels of physical activity during childhood and adolescence, particularly vigorous physical activity, are associated to lower total and central adiposity at this age and later in life; (ii) the level of physical fitness, especially aerobic fitness, is inversely related to current and future adiposity levels; (iii) overweight children and adolescents with a high fitness level have a healthier cardiovascular profile than their overweight, low fit peers and a similar profile to their normal weight, low fit peers. This suggests that high fitness levels may counteract the negative consequences attributed to body fat. These findings suggest that increasing physical fitness in overweight children and adolescents may have many positive effects on health, including lower body fat levels. Copyright © 2012 SEEN.

Full Text Available In order to determine physical fitness differences in students with different cardiorespiratory endurance levels, a study was conducted on a sample of students of the Faculty of Sport and Physical Education at the University of Nis. The sample was divided into two subsamples, where the first subsample comprised 27 female students and the other 35 male students. Physical fitness was assessed using eight tests from the Eurofit battery of tests: the single-leg balance test - for the assessment of general balance, plate tapping - for the assessment of speed of movement, sit-and-reach - for the assessment of flexibility, the standing broad jump - for the assessment of explosive strength, the handgrip test - for the assessment of static strength, sit-ups - for the assessment of repetitive trunk strength, the bent arm hang - for the assessment of muscular endurance and the 10x5 meter shuttle run - for the assessment of the speed/agility. Cardiorespiratory endurance was estimated with the aid of 20 m endurance shuttle-run test. Based on the level of cardiorespiratory endurance, the participants in each subsample, were divided into three groups using a cluster analysis: high (VKRI, average (PKRI and low level (NKRI. The physical fitness differences of students with different cardiorespiratory endurance levels were calculated using the one-way analysis of variance. The results showed that there were no differences in physical fitness of students with different cardiorespiratory endurance levels. Based on the results it can be concluded that the level of cardiorespiratory endurance does not affect the components of physical fitness among students of both sexes.

The purpose of this study was to determine whether physical fitness is linked to academic success in middle school students. The FITNESSGRAM test battery assessed students (n = 838) in the five components of health-related fitness. The Illinois Standardized Achievement Test (ISAT) was used to assess academic achievement in reading and math. The largest correlations were seen for aerobic fitness and muscular endurance (ranging from 0.12 to 0.27, all p reading exams. Girls in the HFZ for aerobic fitness were approximately 2-4 times as likely to meet or exceed reading and math test standards. Aerobic capacity and muscular endurance seem to positively affect academic achievement in middle school students. ©2013 Foundation Acta Paediatrica. Published by John Wiley & Sons Ltd.

The number of children and adolescents participating in organised athletic activities worldwide is increasing. However, physical fitness levels among youth are lower today than in previous decades. The combination of increased exposure and decreased preparedness for sports participation has led to an epidemic of both acute and chronic sports-related injuries in this population. Poor physical fitness, in addition to having negative health consequences, seems to be a risk factor for sports-related injury. Accurate injury surveillance data are required to better define the magnitude of the problem of injury in youth sports, as well as to identify specific risk factors for injury. From these data, targeted intervention strategies incorporating fitness training may be developed with the goal of preventing sports-related injury. Preliminary experience with several specific injury patterns--anterior cruciate ligament injuries and ankle sprains--has demonstrated the efficacy of such targeted prevention strategies.

Full Text Available Aging is a natural and progressive process and physical activities have been indi-cated as a possibility to minimize its impact and, especially, to maintain the functional capacity of older adults for a longer period of time. The objective of the present study was to analyze modifications in the General Functional Fitness Index (GFFI in older adults participating in a physical activity program for a period of 10 months and to associate the results with different age strata, duration of participation in the program and modifications in physical fitness. The study was conducted on 225 older women (mean age: 69.26, sd=5.685, participating in the Physical Activity and Folk Dance Program for The Elderly of the Sports Center, Universidade Federal de Santa Catarina. Descriptive statistics, Student t-test and analysis of variance (ANOVA were used for analysis of the data. A significant difference (p< 0.01 in GFFI and in the variables agility/balance and coordination (p< 0.01 was observed between March and December 2005. Strength (p=0.323, resistance (p=0,946 and flexibility (p=0.722 did not differ significantly during the period analyzed. In addition, the group performing physical activity for more than 10 years and the group older than 80 years presented the best GFFI in the assessments. Physical activity for older adults might be an important factor to improve and/or maintain functional fitness during the process of aging.

A consensus has not been reached among strength and conditioning specialists regarding what physical fitness exercises are most effective to stimulate activity of the core muscles. Thus, the purpose of this article was to systematically review the literature on the electromyographic (EMG) activity of 3 core muscles (lumbar multifidus, transverse abdominis, quadratus lumborum) during physical fitness exercises in healthy adults. CINAHL, Cochrane Central Register of Controlled Trials, EMBASE, PubMed, SPORTdiscus, and Web of Science databases were searched for relevant articles using a search strategy designed by the investigators. Seventeen studies enrolling 252 participants met the review's inclusion/exclusion criteria. Physical fitness exercises were partitioned into 5 major types: traditional core, core stability, ball/device, free weight, and noncore free weight. Strength of evidence was assessed and summarized for comparisons among exercise types. The major findings of this review with moderate levels of evidence indicate that lumbar multifidus EMG activity is greater during free weight exercises compared with ball/device exercises and is similar during core stability and ball/device exercises. Transverse abdominis EMG activity is similar during core stability and ball/device exercises. No studies were uncovered for quadratus lumborum EMG activity during physical fitness exercises. The available evidence suggests that strength and conditioning specialists should focus on implementing multijoint free weight exercises, rather than core-specific exercises, to adequately train the core muscles in their athletes and clients.
Multiple linear regression determined that lean muscle mass and aerobic capacity account for 82% of the variation in the job performance task. Conclusion: Firefighting taxes virtually all aspects of physical fitness. These data help the exercise specialist choose appropriate tests to assess fire-fighters and new recruits, as well ...

We evaluated the association between occupational physical activity and fitness in young workers, taking into account leisure-time physical activity, body size, and smoking. The study population comprised 2188 men and 1987 women, members of the Northern Finland birth cohort 1966, who participated in the 1997-1998 follow-up survey and were employed at the time of the survey. Cardiorespiratory fitness was measured by a 4-min step test and muscular fitness by tests of maximal isometric handgrip and isometric trunk extension. Information on occupational and leisure-time physical activity and smoking was obtained by questionnaire, and body height and weight were measured during medical examination. The data were analyzed by analysis of variance and Cox regression. Men doing heavy physical work scored better in cardiorespiratory fitness, handgrip strength, and trunk muscle endurance than men doing lighter work; the finding for cardiorespiratory fitness was similar in women. The associations were independent of leisure-time physical activity, body weight and height, and smoking. A positive association was found between heavy physical work and a high level of fitness in young workers. Due to limitations of the study setting, causality cannot be asserted, but a training effect of heavy work would not seem unreasonable. Previous studies have suggested a reversal of the positive effect of heavy work on fitness with advancing age. Therefore, regular monitoring of workers' fitness at an early phase is justified to enable assessment of workers' capacity for heavy jobs and any possible need for fitness-improving activities.

Research has consistently demonstrated that parents' values toward physical activity and fitness have strongly influenced the physical activity habits of hearing children (Welk, G. J., Wood, K., & Morss, G. . Parental influences on physical activity in children: An exploration of potential mechanisms. Pediatric Exercise Science, 15, 19-33). The primary purpose of this study was to determine whether similar findings are obtained for deaf (1) children. The influence of parents' hearing status and parents' involvement in Deaf sport (2) was assessed in addition to their values toward sports participation and physical fitness for their deaf children. Deaf children's physical activity habits were determined by the number of activities participated per week, and fitness levels by the number of scores within the Healthy Fitness Zone from the Fitnessgram test. Parents demonstrated positive values toward physical fitness regardless of hearing status; this finding was strongest among deaf parents of deaf children. Significant positive relationships were found among parents' values toward physical fitness and sport participation and children's physical activity and fitness levels, as well as between Deaf sport involvement by deaf parents and children's physical activity levels.

Repeated failure in the Army Physical Fitness Test (APFT) is associated with lower fitness level, premature discharge, and significant career disruption, at high economic and health costs to the individual soldier and the U.S. Army. We used cost-effectiveness analysis to estimate the health and economic implications of two exercise interventions for Army National Guard (ARNG) soldiers who had failed the APFT, a traditional remediation program and a new pedometer-based program called Fitness for Life, involving individual counseling and follow-up telephone calls. Effectiveness of the interventions was analyzed in terms of APFT pass rates and calculated 10-year coronary heart disease risk. Costs were calculated based on tracking of resources used in the programs. APFT pass rates were 54.3% and 47.9%, respectively, for traditional and Fitness for Life programs, p = not significant. Neither program affected 10-year coronary heart disease risk. For assumed APFT pass rates up to 40% without any formal remediation, both the traditional remediation program and the ARNG Fitness for Life intervention had cost savings without significant group differences. Depending on the ARNG unit and personnel preference, although the Fitness for Life Program was more expensive and thus less cost-effective, either program could be cost-effective and of benefit to the military.

Our objective was to analyze the association between different intensities of physical activity (PA), physical fitness, and metabolic syndrome (MS) in young adults. Cross-sectional study including 275 university students, 18-30 years old, from Cuenca, Spain. We evaluated (a) physical activity using accelerometry, (b) aerobic capacity (VO2max), and (c) muscle strength, by a muscle strength index calculated as the sum of the standardized z score of handgrip dynamometry/weight and standing broad jump. An MS index was estimated by summing standardized z scores of waist circumference, ratio of triglycerides to high-density lipoprotein, mean arterial blood pressure, and HOMA-IR. The mean scores of MS index and HOMAIR were significantly higher and the VO2max significantly lower for individuals who did not perform 20 min or more per week of vigorous physical activity. However, those who performed 250 min/week of moderate physical activity showed no significant differences in either VO2max or the MS index when compared with individuals who did not perform this level of activity. The MS index was lower in those with medium-high levels of aerobic capacity. In addition, individuals with medium-high levels of muscular fitness showed lower waist circumference and a lower MS index. VO2max and muscle strength are negatively associated with metabolic risk. 20-min/week of vigorous physical activity was associated with lower cardiometabolic risk in young adults; moderate physical activity did not show association with lower cardiometabolic risk.
Multivariate analyses play an important role in high energy physics. Such analyses often involve performing an unbinned maximum likelihood fit of a probability density function (p.d.f.) to the data. This paper explores a variety of unbinned methods for determining the goodness of fit of the p.d.f. to the data. The application and performance of each method is discussed in the context of a real-life high energy physics analysis (a Dalitz-plot analysis). Several of the methods presented in this paper can also be used for the non-parametric determination of whether two samples originate from the same parent p.d.f. This can be used, e.g., to determine the quality of a detector Monte Carlo simulation without the need for a parametric expression of the efficiency.
INTRODUCTION: Physical fitness is an important attribute in soldiers because military work may be physically demanding. To ensure that military personnel are “fit to fight”, soldiers are typically selected and evaluated based on fitness tests, and physical training and physical activity are emphasized to maintain or develop physical fitness. Existing literature has primarily described fitness and activity levels in full-time soldiers, while reserve soldiers are less frequently investigated. N...
Full Text Available Abstract Background Cardiovascular risk factors are associated with physical fitness and, to a lesser extent, physical activity. Lifestyle interventions directed at enhancing physical fitness in order to decrease the risk of cardiovascular diseases should be extended. To enable the development of effective lifestyle interventions for people with cardiovascular risk factors, we investigated motivational, social-cognitive determinants derived from the Theory of Planned Behavior (TPB and other relevant social psychological theories, next to physical activity and physical fitness. Methods In the cross-sectional Utrecht Police Lifestyle Intervention Fitness and Training (UP-LIFT study, 1298 employees (aged 18 to 62 were asked to complete online questionnaires regarding social-cognitive variables and physical activity. Cardiovascular risk factors and physical fitness (peak VO2 were measured. Results For people with one or more cardiovascular risk factors (78.7% of the total population, social-cognitive variables accounted for 39% (p In addition to the prediction of intention to engage in physical activity and physical active behavior, we explored the impact of the intensity of physical activity. The intentsity of physical activity was only significantly related to physical active behavior (beta = .253, p 2 = .06, p 2 = .23, p For people with one or more cardiovascular risk factors, 39.9% had positive intentions to engage in physical activity and were also physically active, and 10.5% had a low intentions but were physically active. 37.7% had low intentions and were physically inactive, and about 11.9% had high intentions but were physically inactive. Conclusions This study contributes to our ability to optimize cardiovascular risk profiles by demonstrating an important association between physical fitness and social-cognitive variables. Physical fitness can be predicted by physical active behavior as well as by self-efficacy and the intensity of
Full Text Available Purpose: to develop a model of physical fitness training for schoolgirls to surrender standard- tives of physical culture (for example, high jump with a running start. Objectives of the study - to determine the relationship between the levels of development of motor skills and results in the high jump with a running start. Also calculate simple regression equation between them. Material : The study involved 416 school - prostrate aged 10-17. Results : It was found that the greatest influence on the effectiveness of the jump exerts a level of "explosive" force the leg muscles (30,4-47,9 %. The relative influence of mobility power 15,4-23,9 %. The share accounted speed 8,6-15,8 %. Impact indicators flexibility and endurance is 7,6-12,4 % and 4,4-7,2 %. Conclusions : The selection of exercises and methods advantageously carried out after comparing models of physical fitness and the actual state of development of motor characteristics. This makes it possible to determine the quantitative information about the shortcomings of physical fitness of each student (group and specify the direction of future work.
Full Text Available Purpose: to study and find out first year students’ physical condition and physical fitness levels. Material: In the research first year students (n=86 participated. The age of the participants was 16 - 19 years. They passed the following tests for physical fitness: 100 meters’ run; run during 12 minutes; long jump from the spot; chin ups; torso rising from lying to sitting position during 1 minute; forward torso bending from sitting position, cm. Results: it was found that 41% of students have low and below average levels of physical condition and 76.35% - the same physical fitness level (unsatisfactory. So we came to conclusion that it was necessary to review the existing approaches to physical education system. It is recommended to increase the volume of compulsory classes of students’ motor functioning at the cost of the following: usage of optional classes; physical exercises’ practicing in free time; everyday motor activity in the form of morning exercises and sport games. Conclusions: the main reasons of students’ physical condition and physical fitness weakening during their studying are: restricted quantity of academic physical education classes; absence of students’ demand in systemic physical exercises’ practicing; students’ low motivation for physical education; absence of interest in physical exercises’ practicing in free time; students’ health worsening before entering higher educational establishment; imperfectness of school physical education.

The present study examined the sex-specific associations of moderate and vigorous physical activity (VPA) with physical fitness in 300 Japanese adolescents aged 12-14 years. Participants were asked to wear an accelerometer to evaluate physical activity (PA) levels of various intensities (i.e. moderate PA (MPA), 3-5.9 metabolic equivalents (METs); VPA, ≥6 METs; moderate to vigorous PA (MVPA), ≥3 METs). Eight fitness items were assessed (grip strength, bent-leg sit-up, sit-and-reach, side step, 50 m sprint, standing long jump, handball throw, and distance running) as part of the Japanese standardised fitness test. A fitness composite score was calculated using Japanese fitness norms, and participants were categorised according to their score from category A (most fit) to category E (least fit), with participants in categories D and E defined as having low fitness. It was found that for boys, accumulating more than 80.7 min/day of MVPA may reduce the probability of low fitness (odds ratio (ORs) [95% confidence interval (CI)] = 0.17 [0.06-0.47], p = .001). For girls, accumulating only 8.4 min of VPA could reduce the likelihood of exhibiting low fitness (ORs [95% CI] = 0.23 [0.05-0.89], p = .032). These results reveal that there are sex-specific differences in the relationship between PA and physical fitness in adolescents, suggesting that sex-specific PA recommendation may be needed to improve physical fitness in adolescents.

To measure aerobic fitness, muscle strength, fatigue, and physical disability in patients with systemic lupus erythematosus (SLE). Ninety-three patients with SLE and 41 sedentary controls were recruited into the study. Aerobic fitness was assessed by monitoring peak and submaximal oxygen uptake, heart rate, duration of exercise, and perceived exertion during a treadmill-walking test. Strength was measured using voluntary isometric quadriceps contraction. Symptomatic measures included physical and mental fatigue, mood, sleep, and functional incapacity. Compared to sedentary controls patients with SLE had significantly reduced levels of aerobic fitness (mean VO2peak SLE patients, 23.2 ml/kg/min vs controls, 29.6 ml/kg/min; p exercise capacity (mean exercise duration SLE patients, 10.4 min vs controls, 13.1 min; p exercise capacity, reduced muscle strength, more fatigue, and greater disability compared to sedentary controls. Treatments developed to manage depression and improve aerobic fitness should be considered in the overall treatment of fatigue and disability in SLE.

There has been relatively little longitudinal controlled investigation of the effects of yoga on general physical fitness, despite the widespread participation in this form of exercise. The purpose of this exploratory study was to examine the effect of short-term Bikram yoga training on general physical fitness. Young healthy adults were randomized to yoga training (N = 10, 29 ± 6 years, 24 sessions in 8 weeks) or a control group (N = 11, 26 ± 7 years). Each yoga training session consisted of 90-minute standardized supervised postures performed in a heated and humidified studio. Isometric deadlift strength, handgrip strength, lower back/hamstring and shoulder flexibility, resting heart rate and blood pressure, maximal oxygen consumption (treadmill), and lean and fat mass (dual-energy x-ray absorptiometry) were measured before and after training. Yoga subjects exhibited increased deadlift strength, substantially increased lower back/hamstring flexibility, increased shoulder flexibility, and modestly decreased body fat compared with control group. There were no changes in handgrip strength, cardiovascular measures, or maximal aerobic fitness. In summary, this short-term yoga training protocol produced beneficial changes in musculoskeletal fitness that were specific to the training stimulus.

The aim of this study was to verify the effects of programmed and self-selected physical activities on the physical fitness of adolescents. High school adolescents, aged between 15 and 17 years, were divided into two experimental groups: a) a self-selected physical activity group (PAS) with 55 students (aged 15.7 ± 0.7 years), who performed physical activities with self-selected rhythm at the following sports: basketball, volleyball, handball, futsal and swimming; and b) a physical fitness training group (PFT) with 53 students (aged 16.0 ± 0.7 years), who performed programmed physical fitness exercises. Both types of activity were developed during 60 min classes. To assess physical fitness the PROESP-BR protocol was used. The statistical analysis was performed by repeated measures ANOVA. The measurements of pre and post-tests showed significantly different values after PFT in: 9 minute running test, medicine ball throw, horizontal jump, abdominal endurance, running speed and flexibility. After PAS differences were detected in abdominal endurance, agility, running speed and flexibility. The intervention with programmed physical activity promoted more changes in the physical abilities; however, in the self-selected program, agility was improved probably because of the practice of sports. Therefore, physical education teachers can use PFT to improve cardiorespiratory fitness and power of lower and upper limbs and PAS to improve agility of high school adolescents.

Reduction mammaplasty is known for excellent outcomes and patient satisfaction. Although patients report improvements in pain, weight loss, and exercise levels, objective data on physical fitness benefits are limited. Using the Stanford Military Data Repository, we identified 89 US Army active duty women with at least 1 pre- and postoperative Army Physical Fitness Test (APFT) who underwent reduction mammaplasty during 2011 to 2014. We used paired t tests to compare pre- and postoperative APFT score means and raw values for push-ups, sit-ups, and the 2-mile run. There were 56 subjects (62.9%) who improved in total APFT scores. Total score means increased from 235.9 preoperatively to 243.4 postoperatively (P = 0.0065). Of 28 subjects with at least 2 APFT scores before and after surgery, 20 (71.4%) improved in total scores. The subgroup's mean total score increased from 237.8 to 251.3 (P = 0.0009). Comparing individual pre- and postprocedure APFTs, all subjects demonstrated a mean 3.9% (SD, 0.1) improvement in total scores, and the subpopulation of 28 improved by 6.3% (SD, 0.1). In all events, mean performance values trended toward better postoperative scores. Differences were statistically significant for the total population for the number of sit-ups (P = 0.035), and, for the subgroup of 28, differences were statistically significant for the total score (P = 0.0009), sit-ups (P = 0.0002), and push-ups (P = 0.0134). Reduction mammaplasty was associated with postoperative physical fitness improvements among US Army active duty women. Soldier data are useful for objectively assessing physical fitness effects of breast reduction surgery.

One in three children in North America are considered overweight or obese. Children with intellectual and developmental disabilities (IDD) are at an increased risk for obesity than their typically developing peers. Decreased physical activity (PA) and low physical fitness may be contributing factors to this rise in obesity. Because children with IDD are at an increased risk of diseases related to inactivity, it is important to improve health-related physical fitness to complete activities of daily living and improve health. The focus of this research is on improving the performance of physical fitness components through physical activity programming among a group of children with IDD, ages 7-12 years. The Brockport Physical Fitness Test was used assess levels of physical fitness of 35 children with IDD (25 boys, 10 girls) before and after participation in a 10-week program. The results of paired sampled t-tests showed participation in 15-h PA program can significantly increase aerobic capacity and muscular strength and endurance in children with IDD. This study is aimed at understanding the role of PA in helping children with IDD to develop the fitness capacities essential to participation in a wide variety of activities.

Antipsychotics are used increasingly in adolescents for a range of psychiatric disorders. The aim of the current study was to investigate whether physical activity levels and physical fitness of adolescent inpatients treated with antipsychotic medication, differs from either (i) antipsychotic naïve adolescents with mental health problems and, (ii) healthy controls. All participants completed the Physical Activity Questionnaire for Adolescents, the Positive-and-Negative-Affect-Schedule and performed the Eurofit test battery. Adolescents with mental health problems (irrespective of antipsychotic medication) were significantly (Pphysically active and had an impaired whole body balance, running speed and cardiovascular endurance compared to healthy controls (n=15, 8♂, 15.9±1.3 years). Adolescents treated with antipsychotic medication (n=15, 8♂, 15.5±1.3 years) were less physically active and had an impaired whole body balance compared with antipsychotic naïve adolescents (n=15, 8♂, 15.7±1.4 years). Given the overwhelming deleterious impact of physical inactivity and low physical fitness on physical and mental health outcomes, interventions specifically targeting physical activity and physical fitness among adolescents experiencing mental illness, both treated with, and not treated with antipsychotic medication are warranted as a priority. Antipsychotic medication should be considered as a risk factor for physical inactivity and poor physical fitness. Copyright © 2016 Elsevier Ireland Ltd. All rights reserved.

Background: Eating disorders are health problems that are particularly prevalent in adolescents and young adults. They are associated with considerable physical health and psychosocial morbidity, and increased risk of mortality. We set out to conduct a systematic review to determine their effect on physical fitness in the general population and on sport performance in athletes. Methods/Design: A systematic review of the relevant peer-reviewed literature was performed. For inclusion, articles retrieved from PubMed had to be published in English between 1977 and 2013. Wherever possible, methods and reporting adhere to the guidelines outlined in the PRISMA statement. Some additional studies were retrieved from among those cited in the reference lists of included studies and from non-electronic databases. Literature searches, study selection, method and quality appraisal were performed independently by two authors, and data was synthesized using a narrative approach. Results: Of the 1183 articles retrieved, twenty-nine studies met the inclusion criteria and were consequently analysed. The available data indicate that eating disorders have a negative effect on physical fitness and sport performance by causing low energy availability, excessive loss of fat and lean mass, dehydration, and electrolyte disturbance. Discussion: Although the paucity of the available data mean that findings to date should be interpreted with caution, the information collated in this review has several practical implications. First, eating disorders have a negative effect on both physical fitness and sport performance. Second athletics coaches should be targeted for education about the risk factors of eating disorders, as deterioration in sport performance in athletes, particularly if they are underweight or show other signs of an eating disorder, may indicate the need for medical intervention. However, future studies are needed, especially to assess the direct effect of eating disorders on

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.

The current research examined the relationships among exercise goal contents, behavioral regulation, physical activity, and aerobic fitness within the context of eight-week university physical education courses. Participants were undergraduate students (M age = 20.2 year, SD = 2.3) enrolled in activity courses (N = 461) during the 2010 Fall semester. At pretest, participants completed a demographic survey, Behavioral Regulation in Exercise Questionnaire and the Goal Contents in Exercise Questionnaire. At eight-week posttest, participants completed the Physical Activity Questionnaire for Adults and the PACER aerobic fitness test. Relative intrinsic goal content was found to predict physical activity indirectly and aerobic fitness via behavioral regulation. Specific goal contents related to health management and skill development were found to predict physical activity and aerobic fitness via a fully mediated path through identified and intrinsic regulation. Results supported the efficacy of goal contents and self-determination theory in describing physical activity behavior and fitness. Examining specific types of goal contents and behavioral regulations revealed relationships that were masked by the utilization of omnibus scoring protocols. © The Author(s) 2016.

The metabolic syndrome is defined as the coexistence of multiple cardiovascular and diabetes risk factors, the prevalence of which has increased dramatically in adult populations in the last decades. More recently, the same cluster of metabolic risk factors has also been recognized in children and adolescents. Epidemiological evidence suggests that high levels of cardiorespiratory fitness (CRF) and physical activity are associated with a favorable metabolic risk profile in adults. However, in youth the role of these factors is less clear. Therefore, the purpose of this mini-review is to examine the recent evidence between objectively measured habitual physical activity and CRF with clustered metabolic risk in youth. In general, it appears that both physical activity and CRF are separately and independently associated with metabolic risk factors in youth, possibly through different causal pathways. Further research is necessary to quantify how much physical activity is needed to prevent the metabolic syndrome and the diseases with which it is associated. Public health approaches that encourage increased physical activity and reduce sedentary behaviors may prove useful in reducing the population burden associated with metabolic risk.

The purpose of this study was to examine the influence of physical fitness (PF) on the development of subcutaneous adipose tissue in children followed longitudinally over a 9 year period ranging from childhood to adolescence. This longitudinal study followed 518 healthy participants (262 boys, 256 girls) over a 9-year period ranging from childhood (age 6) to adolescence (age 15). Adiposity (triceps and subscapular skinfolds), and fitness (60s sit-ups, flexed arm hang, standing long jump, 50m dash, 10m shuttle run, sit-and-reach, and 20m pacer run) were assessed at four annual time points during primary school, and on a follow up, 6 years later, during secondary school. Growth in subcutaneous fat was modeled within a HLM statistical framework, using fitness components as time changing predictors. Flexed arm hang (β=-0.059; p=0.000), standing long jump (β=-0.072; p=0.000), 60s sit-ups (β=-0.041; p=0.040), 50m dash (β=0.956; p=0.000), and 20m PACER (β=-0.077; p=0.000) tests, were found to predict changes on body fat growth over the years, independently of sex. Improving PF individual levels can positively influence adiposity deposition over the time period covering childhood and adolescence. That occurs independently of the typical sex differentiated adiposity growth. Copyright © 2012 Sports Medicine Australia. Published by Elsevier Ltd. All rights reserved.

Obesity in children and young adult is associated with cardiovascular risk in short term and long term. The aim of this study was to describe the profile of the cardiovascular functions parameters and physical fitness in overweight. This is an analytical observational study with cross sectional approach. The samples of this study were 85 randomly selected subjects aged 18 to 24 years with normoweight and body mass index parameters measures were body mass index (BMI), waist circumference (WC), waist-hip ratio (WHR), cardiovascular function parameters (resting pulse, blood pressure, and peak flow meter) and physical fitness parameters (VO2max dengan McArdle step test). The mean BMI was 24,53±4,929. The WC and WHR mean were 86,7±14,10 cms and 0,89±0,073 cm respectively. The mean of resting pulses were higher in normoweight subject (p=0,0209). The mean systole were lower in normoweight subject (p=0,0026). No differences VO2 max between groups (p=0,3888). The peak flow meter was higher in normoweight (p=0,0274). The result of this study indicate that heart rate, systole and peak flow meter are signifantly different between groups. The heart rate and the peak flow meter in the overweight subjects were lower meanwhile the systole blood pressure was higher compared to normoweight subjects.

The aim of the study was to determine how different categorizations of self-reported and objectively measured physical activity (PA) reflect variations in cardiorespiratory fitness (VO2max ). A total of 759 individuals (366 women) with a mean age of 48.5 years (SD 14.4) wore an accelerometer (ActiGraph GT1M) for seven consecutive days and answered the short International Physical Activity Questionnaire (IPAQ). VO2max was directly measured during a continuous graded exercise treadmill test until exhaustion. Men and women categorized as highly active by IPAQ had 9% and 13% higher VO2max , respectively, than those reporting a low PA level (P differences in average sedentary time, analyzed in total min/day and in bouts of 10 and 30 min, were found between participants with high or low cardiorespiratory fitness. However, women spent less time than men in bouts of sedentary behaviors. Self-reported PA by IPAQ and objectively measured PA by accelerometer were both useful instruments for detecting differences in VO2max . © 2015 John Wiley & Sons A/S.

Full Text Available Physical activity (PA and cardiorespiratory fitness (CRF are associated with better cognitive function in late life, but the neural correlates for these relationships are unclear. To study these correlates, we examined the association of both PA and CRF with measures of white matter (WM integrity in 88 healthy low-fit adults (age 60-78. Using accelerometry, we objectively measured sedentary behavior, light PA, and moderate to vigorous PA (MV-PA over a week. We showed that greater MV-PA was related to lower volume of WM lesions. The association between PA and WM microstructural integrity (measured with diffusion tensor imaging was region-specific: light PA was related to temporal WM, while sedentary behavior was associated with lower integrity in the parahippocampal WM. Our findings highlight that engaging in PA of various intensity in parallel with avoiding sedentariness are important in maintaining WM health in older age, supporting public health recommendations that emphasize the importance of active lifestyle.

We live in a connected world. It is of great practical importance and intellectual appeal to understand the networks surrounding us. In this work we study ranking of the nodes in complex networks. In large networks such as World Wide Web (WWW) and citation networks of scientific literature, searching by keywords is a common practice to retrieve useful information. On the WWW, apart from the contents of webpages, the topology of the network itself can be a rich source of information about their relative importance and relevancy to the search query. It is the effective utilization of this topological information  which advanced the Google search engine to its present position of the most popular tool on the WWW. The World-Wide Web (WWW) is characterized by a strong community structure in which communities of webpages are densely interconnected by hyperlinks. We study how such network architecture affects the average Google ranking of individual webpages in the community. Using a mean-field approximation, we quantify how the average Google rank of community's webpages depends on the degree to which it is isolated from the rest of the world in both incoming and outgoing directions, and alpha -- the only intrinsic parameter of Google's PageRank algorithm. We proceed with numerical study of simulated networks and empirical study of several internal web-communities within two US universities. The predictions of our mean-field treatment were qualitatively verified in those real-life networks. Furthermore, the value alpha = 0.15 used by Google seems to be optimized for the degree of isolation of communities as they exist in the actual WWW. We then extend Google's PageRank algorithm to citation networks of scientific literature. Unlike hyperlinks, citations cannot be updated after the point of publication. This results in strong aging characteristics of citation networks that affect the performance of the PageRank algorithm. To rectify this we modify the Page
Full Text Available The main aim of the study was to examine whether relationships exist between particular temperamental traits within the concept of Regulative Theory of Temperament and components of physical fitness, that are most crucial for success in sport. The research involved 108 individuals including 63 men (age 21.1 ± 1.6 yrs and 45 women (age 20.7 ± 1.3 yrs. None of the respondents were professionally engaged in sport. Components of physical fitness included: aerobic capacity, strength, agility, static-dynamic balance and reaction time. The respondents also completed two questionnaires: the Formal Characteristics of Behaviour – Temperament Inventory and the International Physical Activity Questionnaire. The results indicate that the temperamental traits had average to poor correlations with the components of physical fitness, whereas more statistically significant correlations were observed in women. Negative correlations were obtained between emotional reactivity and agility, which was a result confirmed by previous research. All temperamental traits related with the energetic aspects of behaviour correlated with simple reaction time in women. Physical activity and aerobic capacity did not correlate with any of the studied traits. The results do not allow for any general conclusions to be drawn, but can serve as a reference point for future research on temperamental traits as delineated by Regulative Theory of Temperament and their relationship with the components of physical fitness.

Full Text Available The aim of this study was to compare physical activity, sedentary behavior and physical fitness between full-time and part-time students. The sample consisted of 72 students (9 to 12 years, 34 of them studying full time. The subjects answered a questionnaire about physical activity, sedentary behavior, and sociodemographic characteristics. Data regarding sexual maturation, body composition and physical fitness were also collected. The results showed that girls studying full time spent less time per day in sedentary behavior compared to part-time girls (p<0.05. Analysis of anthropometric variables showed a significantly lower body fat percentage in boys studying full time. With respect to the physical fitness tests, significant differences were identified in the sit and reach test, horizontal jump, medicine ball throw and agility, with the observation of higher performance in full-time students. Similarly, girls studying full time exhibited significantly higher performance in the horizontal jump and agility tests compared to their peers. It can be concluded that full-time students spend less time in sedentary behavior and exhibit better physical fitness indices in most of the tests used, irrespective of gender.

The purpose of this study was to examine the effects of cardiorespiratory fitness and weight status on knowledge of physical activity and fitness (PAF knowledge), attitude toward physical education (PE), and physical activity. A total of 343 middle school students participated in the study (Age: M/SD = 12.76/.94, ranging from 11 to 14 years old). PE Metrics™ was used to measure PAF knowledge, and Attitude toward Physical Education Questionnaire and Youth Activity Profile were used to measure attitude, physical activity and sedentary behavior. Fitness and weight status were assessed using FitnessGram and converted to in Healthy Fitness Zone (HFZ) or Not in HFZ. Two-way multivariate analyses of covariance (MANCOVA; gender and grade as covariates) showed a significant group effect for cardiorespiratory fitness (Λ Pilla = .07, F 4,255 = 5.03, p = .001, [Formula: see text] = .07) but not for weight status (p = .57). PAF knowledge (F 1,258 = 9.49, p < .01, [Formula: see text]= .04), attitude (F 1,258 = 4.45, p < .05, [Formula: see text]= .02) and sedentary behavior (F 1,258 = 6.89, p < .01, [Formula: see text]= .03) all favored the HFZ group. The findings reinforce the importance of promoting cardiorespiratory fitness in middle school PE as students acquire attitude, knowledge, and behaviors needed for active-living.

The aim of this study was to quantify the complexity of contact lens (CL) fitting following penetrating keratoplasty (PKP).The CL care of 40 eyes following PKP was analyzed retrospectively and compared to that of 40 age-matched and gender-matched controls. We evaluated the numbers of diagnostic and ordered rigid gas permeable (RGP) CLs, office visits for 6-month follow-up, best spectacle and RGP CL-corrected logMar visual acuities (VAs), and RGP CL success and complication rates. Post-PKP corneas required more diagnostic CLs (p = 0.009), ordered CLs (p = 0.0003), and office visits (p = 0.001) than did controls. Corrected logMAR VAs post-PKP improved from 0.31 +/- 0.31 (mean +/- SD) with spectacles (20/41) to 0.076 +/- 0.19 (20/24) with RGP CLs (p complications; these differences did not reach statistical significance.Post-PKP eyes require more diagnostic CLs, ordered CLs, and professional office visits. They also have greater improvement of VAs with RGPs than normals compared to spectacles. CL wear post-PKP does not statistically increase the rate of CL complications or alter the success rate of CL wear.

With the advent of the era of global high-tech industry and commerce and its associated sedentary lifestyle, opportunities for physical activity are reduced. People's physical fitness and health is deteriorating. Therefore, it is necessary to develop a system that can enhance people's physical fitness and health. However, it is difficult for general physical fitness and healthcare systems to meet individualized needs. The main purpose of this research is to develop a method of intelligent diagnosis and prescription for a customized physical fitness and healthcare system. The proposed system records all processes of the physical fitness and healthcare system via a wireless sensor network and the results of the diagnosis and prescription will be generated by fuzzy logic inference. It will improve individualized physical fitness and healthcare. Finally, we demonstrate the advantages of intelligent diagnosis and prescription for a customized physical fitness and healthcare system.

The purpose of this study was to determine the extent to which a sport education season of fitness could provide students with recommended levels of in-class moderate-to-vigorous physical activity (MVPA) while also increasing students' fitness knowledge and fitness achievement. One hundred and sixty-six 5th-grade students (76 boys, 90 girls) participated in a 20-lesson season called "CrossFit Challenge" during a 4-week period. The Progressive Aerobic Cardiovascular Endurance Run, push-ups, and curl-ups tests of the FITNESSGRAM® were used to assess fitness at pretest and posttest, while fitness knowledge was assessed through a validated, grade-appropriate test of health-related fitness knowledge (HRF). Physical activity was measured with Actigraph GT3X triaxial accelerometers. Results indicated a significant time effect for all fitness tests and the knowledge test. Across the entire season, the students spent an average of 54.5% of lesson time engaged in MVPA, irrespective of the type of lesson (instruction, free practice, or competition). The results suggest that configuring the key principles of sport education within a unit of fitness is an efficient model for providing students with the opportunity to improve fitness skill and HRF knowledge while attaining recommended levels of MVPA.
This study is one of a series designed to support Air Force leaders in promoting resilience among its Airmen, civilian employees, and Air Force family members. It examines the relationship between physical fitness and resilience, using key constructs found in the scientific literature that address work-related physical fitness and health-related physical fitness. Supporting or increasing the levels of physical fitness identified in this study may facilitate resilience and can protect Airmen, civilian employees, and Air Force families from the negative effects of stress. The study also reviews interventions designed to promote physical fitness applicable at the individual, unit, family, and community levels.

Texas Senate Bill 530 (2007) mandated fitness assessment as part of the annual K-8 Physical Education (PE) curricula, yet no studies have reported interventions designed to improve and quantify individual student passing rates or individual school performance. Students (Total 2008-2010 N=1484; 729 females, 755 males; mean age = 11.85 y; mean BMI = 22.69 or > 90%-tile, overweight) were evaluated on individual FITNESSGRAM® performances in a cross-sectional analysis of 6th graders comparing baseline scores (year 1) with outcomes of a physical activity intervention in years 2 and 3. Students participated in regular PE classes (including campus wellness center activities) with a once a week focus (FITNESSGRAM® Friday) on improving mile run scores and other assessment scores. Students significantly improved FITNESSGRAM® scores following the PE intervention to levels similar to state reported averages. On average, boys improved their pushups by 32.7%, trunk lift by 17.4% and mile run times by 29.5%. Averages for girls improved by 15.4% for pushups, 6.7% for truck lift, and by 38.6% for the mile run. The percentage of boys in our study achieving all six FITNESSGRAM® tests in the HFZ was 3% at baseline and 22% following intervention. The percentage of girls meeting the criteria for the HFZ on all six FITNESSGRAM® tests was 4.5% at baseline and 20% following intervention. This study provides a potential model for fitness success in other middle school PE interventions, in Texas and the nation.

Full Text Available The purpose of the study is to examine the associations of youth physical activity and screen time with weight status and cardiorespiratory fitness in children and adolescents, separately, utilizing a nationally representative sample. A total of 1,113 participants (692 children aged 6-11 yrs; 422 adolescents aged 12-15 yrs from the 2012 NHANES National Youth Fitness Survey. Participants completed physical activity and screen time questionnaires, and their body mass index and cardiorespiratory fitness (adolescents only were assessed. Adolescents completed additional physical activity questions to estimate daily MET minutes. Children not meeting the screen time guideline had 1.69 times the odds of being overweight/obese compared to those meeting the screen time guideline, after adjusting for physical activity and other control variables. Among adolescent, screen time was significantly associated with being overweight/obese (odds ratio = 1.82, 95% confidence interval: 1.06-3.15, but the association attenuated toward the borderline of being significant after controlling for physical activity. Being physically active was positively associated with cardiorespiratory fitness, independent of screen time among adolescents. In joint association analysis, children who did not meet physical activity nor screen time guidelines had 2.52 times higher odds of being overweight/obese than children who met both guidelines. Adolescents who did not meet the screen time guideline had significantly higher odds ratio of being overweight/obese regardless of meeting the physical activity guideline. Meeting the physical activity guideline was also associated with cardiorespiratory fitness regardless of meeting the screen time guideline in adolescents. Screen time is a stronger factor than physical activity in predicting weight status in both children and adolescents, and only physical activity is strongly associated with cardiorespiratory fitness in adolescents.

The so-called toxic triad of factors linked to cancer, namely obesity, poor cardiorespiratory fitness and physical inactivity, increase the risk of cancer and, when cancer is present, worsen its prognosis. Thus, obesity and a sedentary lifestyle have been linked to an elevated cancer risk whereas regular physical exercise and good cardiorespiratory function (CRF) diminish this risk. Despite genetic risk factors, there is evidence to show that some lifestyle modifications are capable of reduci...

Within the past few years, the U.S. Army and U.S. Marine Corps have either incorporated or in the process of incorporating physical fitness tests that assess a soldier's fitness capability in a combat environment. In this article, we investigate how the U.S. Air Force Physical Fitness Test (AFPFT) events compare to sister-services' physical fitness test events with respect to their predictability of a proxy for combat fitness. Using linear regression via ordinary least squares, we demonstrate that the AFPFT correlates poorly with an airman's combat fitness. AFPFT scores had minimal predictability (adjusted R2 0.20-0.23). Investigating all of the individual events from the three services tests, we develop a new Air Force fitness to consider and to adopt. The test incorporates a timed 1/2-mile run, 30-lb dumbbell lifts in 2 minutes, and maximum number of push-ups in 1 minute. The adjusted R2 for this model was 0.90, an almost 300% improvement over the current test, in terms of predicting combat fitness.

Physical fitness (PF) is a construct of health- and skill-related attributes which have been associated with academic performance (AP) in youth. This study aimed to review the scientific evidence on the association among components of PF and AP in children and adolescents. A systematic review of articles using databases PubMed/Medline, ERIC, LILACS, SciELO, and Web of Science was undertaken. Cross-sectional and longitudinal studies examining the association between at least one component of PF and AP in children and adolescents, published between 1990 and June 2016, were included. Independent extraction of articles was carried out by the two authors using predefined data fields. From a total of 45 studies included, 25 report a positive association between components of PF with AP and 20 describe a single association between cardiorespiratory fitness (CRF) and AP. According to the Strengthening the Reporting of Observational Studies in Epidemiology guidelines: 12 were classified as low, 32 as medium risk, and 1 as high risk of bias. Thirty-one studies reported a positive association between AP and CRF, six studies with muscular strength, three studies with flexibility, and seven studies reported a positive association between clustered of PF components and AP. The magnitude of the associations is weak to moderate (β = 0.10-0.42 and odds = 1.01-4.14). There is strong evidence for a positive association between CRF and cluster of PF with AP in cross-sectional studies; and evidence from longitudinal studies for a positive association between cluster of PF and AP; the relationship between muscular strength and flexibility with AP remains uncertain. © 2016 John Wiley & Sons A/S.

We studied reported frequency of physical activity (PA), body composition, and fitness in Kuwaiti females (n = 84) and males (n = 72), urban office government employees, or students. A sedentary (SED) group reported no or occasional participation in self-directed PA of 30 minutes or more during the week for the last 6 months; group LOF (low frequency) participated in 1-2 sessions/week (walking, jogging, sports such as volleyball, soccer, or gym); group HIF (higher frequency) reported three or more sessions/week. Aerobic fitness was measured using Bruce's treadmill protocol. Body fat and fat-free mass (FFM) were estimated from seven skinfolds and body weight (BW). Grip strength and trunk flexibility were also measured. Maximal O(2) consumption (VO(2)max)/BW was proportional to reported frequency of PA in males and females, indicating reliability of the reported PA frequencies. SED males (%fat > 25), SED and LOF females (%fat > 30) were overweight. In males, LOF PA was associated with lower %fat and higher flexibility than SED, and in females with higher VO(2)max/FFM than SED. LOF females, in contrast to males, were resilient to or exercised at levels insufficient for fat loss but sufficient for aerobic conditioning of the FFM, likely related to the low VO(2)max of females in which PA would have the most effect. HIF PA (>/=3/week) was associated in females with significantly lower %fat and higher flexibility than SED females and no further aerobic conditioning of the FFM, and in males with no further differences in study variables compared with LOF males. Grip strength was higher in males than females but was unrelated to frequency of PA, likely reflecting lack of strength training in the activities of most participants. Thus, low-frequency PA was associated with health benefits both in males (lower %fat) and females (higher VO(2)max/FFM). Probably due to the generally low fitness level of females and, hence, the high aerobic effort (%VO(2)max) required for exercise

To report baseline data from a physical activity (PA) intervention for Latina breast cancer survivors, and assess the relationship between PA, fitness, and disability. Eighty-nine Latina breast cancer survivors from San Juan, PR and Houston, TX (age: 55.4 ± 9.9 years; BMI: 29.87 ± 5.62 kg/m 2 ; ≥ 3 months post-treatment) participated in this study. At baseline participants completed fitness testing (six-minute walk test [6MWT], 30-second sit-stand; grip strength, lower and upper extremity and low back strength, shoulder range of motion, balance testing), and assessment of physical activity (PA) and disability. PA was assessed using the International Physical Activity Questionnaire (IPAQ). A subsample (n = 27) received an accelerometer to compare objective versus self-reported PA. Participants exhibited low PA (M = 76.5 MET·minutes/week; SD = 183.4), poor fitness (6MWT M = 436.4 meters, SD = 99.1; 30s sit-stand, M = 11.6 stands, SD = 3.1), and no detectable disability. In an adjusted model lower extremity fitness was associated with PA, with a one repetition increase in sit-to-stand associated with 49 additional minutes of self-reported PA plus walking per week. The correlation between IPAQ moderate-vigorous PA and accelerometer was 0.38 (p = 0.047). Latina breast cancer survivors have low physical activity and fitness levels that increase their risk of disability, cardiometabolic comorbidities, and potential cancer recurrence.

Self-assembly is ubiquitous in physics, chemistry and biology, and has many applications in materials science and engineering. Here we present a general approach for finding the simplest set of building blocks that will assemble into a given physical structure. Our procedure can be adapted to any given geometry, and thus to any given type of physical system. The amount of information required to describe this simplest set of building blocks provides a quantitative measure of the structure's physical complexity, which is capable of detecting any symmetry or modularity in the underlying structure.We also introduce the notions of joint, mutual and conditional complexity for self-assembling structures. We illustrate our approach using self-assembling polyominoes, and demonstrate the breadth of its potential applications by using it to quantify the physical complexity of protein complexes.

Because of the perceived lack of youth physical fitness and/or concerns for increased obesity, physical education teachers are interested in youth fitness and physical activity levels. Statewide mandates are being developed that require school-based teachers to complete physical fitness testing. Data from the nationally representative School Health Policies and Programs Study 2000 were analyzed to investigate the prevalence of fitness testing and the professional characteristics of fitness test users. Data were collected with teachers of either randomly selected classes in elementary schools and randomly selected required physical education courses in middle/junior high and senior high schools (N = 1,564). The prevalence of fitness test use is 65% across all school levels. Variables associated with physical fitness test usage were professionally oriented. Results showed that teachers in secondary schools (odds ratio [OR] = 2.25, 95% confidence interval [CI] = I.18-4.27), those with degrees in physical education/kinesiology-related disciplines (OR = 2.01, 95% CI = 1.11-3.63), and those who had completed staff development on physical fitness testing (OR = 3.22, 95% CI = 1.86-5.60) were more likely than respondents without these characteristics to engage in physical fitness testing. Results changed little when separate analyses were conducted for classes/courses in districts requiring versus not requiring fitness testing. Financial variables, including fitness-oriented facilities available, metropolitan location, and discretionary expenditures per student, were not associated with fitness test use. Results provided national prevalence of school-based physical fitness testing use in the U. S. and conveyed information about those who currently use physical fitness tests.

People with posttraumatic stress disorder (PTSD) have an increased risk of cardiovascular diseases (CVD). Physical fitness is a key modifiable risk factor for CVD and associated mortality. We reviewed the evidence-base regarding physical fitness in people with PTSD. Two independent reviewers searched PubMed, CINAHL, PsycARTICLES, PEDro, and SPORTDiscus from inception until May 2016 using the key words "fitness" OR "exercise" AND "posttraumatic stress disorder" OR "PTSD". In total, 5 studies involving 192 (44 female) individuals with PTSD met the inclusion criteria. Lower baseline physical fitness are associated with greater reductions in avoidance and hyperarousal symptoms, as well as with total, physical, and social symptoms of anxiety sensitivity. Rigorous data comparing physical fitness with age- and gender matched general population controls are currently lacking. The research field regarding physical fitness in people with PTSD is still in its infancy. Given the established relationships between physical fitness, morbidity and mortality in the general population and the current gaps in the PTSD literature, targets for future research include exploring: (a) whether people with PTSD are at risk of low physical fitness and therefore in need of intensified assessment, treatment and follow-up, (b) the relationships among physical fitness, overall health status, chronic disease risk reduction, disability, and mortality in individuals PTSD, (c) psychometric properties of submaximal physical fitness tests in PTSD, (d) physical fitness changes following physical activity in PTSD, and (e) optimal methods of integrating physical activity programs within current treatment models for PTSD. Implications for Rehabilitation People with PTSD should aim to achieve 150 minutes of moderate or 75 minutes vigorous physical activity per week while also engaging in resistance training exercises at least twice a week. Health care professionals should assist people with PTSD to

We examined mean effects and variance moderating effects of measures of physical activity and fitness on six measures of adiposity and their reciprocal effects in a subsample of the population-representative Danish Twin Registry. Consistent with prior studies, higher levels of physical activity...... these reciprocal effects are uniform. Some variance moderating effects also appeared due to biases in individual measures of adiposity, as well as to differences and inaccuracies in measures of physical activity. This suggests a need to avoid reliance on single measures of both physical activity and adiposity...... in attempting to understand the pathways involved in their linkages, and constraint in interpreting results if only single measures are available. Future research indications include identifying which physical activity-related environmental circumstances have relatively uniform effects on adiposity in everyone...

Full Text Available The objective of this study was to determine the influence of programmed physical activity on the physical fitness of adolescent students over one school year. The sample consisted of 383 students (age range: 10 to 14 years divided into two groups: 186 cases (96 boys and 90 girls and 197 controls (108 boys and 89 girls. An intervention study with pre- and post-tests was conducted, in which the intervention group was submitted to programmed physical activity, while the control group underwent conventional classes of school physical education. Physical fitness was assessed by sit-and-reach (flexibility, muscle endurance (elbow flexion and extension and aerobic endurance (run/walk, 9 min tests. Motor performance observed in the three tests (flexibility, strength and endurance did not improve from pre-test to post-test in either group, but comparison of the intervention and control groups showed significant improvement in the strength and endurance tests for both genders in the intervention group. Boys of the two groups also showed dominance in the strength and endurance tests. In general, higher muscle strength and cardiorespiratory fitness and lower flexibility were observed for boys when compared to girls, and all parameters increased in the post-test and were higher in the intervention group compared to control A significant difference in flexibility was only observed between genders. With respect to muscle strength, a significant difference was observed between genders and between the intervention and control group after adjustment for age and socioeconomic level. Cardiorespiratory fitness differed significantly between genders and between the intervention and control group.

The Department of Defense (DoD) has mandated development of a system to collect and manage data on the weight, percent body fat (%BF), and fitness of all military personnel. This project aimed to (1) develop a computerized weight and fitness database to track individuals and Army units over time allowing cross-sectional and longitudinal evaluations and (2) test the computerized system for feasibility and integrity of data collection over several years of usage. The computer application, the Military Services Fitness Database (MSFD), was designed for (1) storage and tracking of data related to height, weight, %BF for the Army Weight Control Program (AWCP) and Army Physical Fitness Test (APFT) scores and (2) generation of reports using these data. A 2.5-year pilot test of the MSFD indicated that it monitors population and individual trends of changing body weight, %BF, and fitness in a military population.

Full Text Available With the advent of global high-tech industry and commerce era, the sedentary reduces opportunities of physical activity. And physical fitness and health of people is getting worse and worse. At present, the shortage of physical fitness instructors greatly affected the effectiveness of health promotion. Therefore, it is necessary to develop an auxiliary system which can reduce the workload of instructors and enhance physical fitness and health for people. But current general physical fitness and healthcare system is hard to meet individualized needs. The main purpose of this research is to develop an intelligent auxiliary system for customized physical fitness and healthcare. It records all processes of physical fitness and healthcare system by wireless sensors network. The results of intelligent auxiliary systems for customized physical fitness and healthcare will be generated by fuzzy logic Inference. It will improve individualized physical fitness and healthcare. Finally, we will demonstrate the advantages of the intelligent auxiliary system for customized physical fitness and healthcare.

The aim of this study was to investigate if physical fitness (strength/power, endurance, flexibility and coordination) mediates the cross-sectional relationship between physical activity and physical self-perception (athletic competence and physical appearance) in a sample of 15-year old adolescents. We wanted to investigate the relative strength of each indirect effect. The present data are taken from two waves of a larger data collection for the project "Youth in Balance", and was collected in the autumn of 2005 (N = 1207) and 2008 (N = 632). A total of 1839 students (889 girls and 950 boys) from 12 schools in Kristiansand took part. A bias-corrected bootstrapping technique was used to examine indirect effects. Results revealed that cardiovascular endurance, lower-body strength/power, and upper-body strength stood out as unique mediators in the relationship between physical activity and athletic competence in both genders. Furthermore, there was an indirect effect of physical activity on physical appearance through physical strength/power and flexibility in males. No indirect effects of physical activity on physical appearance through actual physical fitness indices were detected in females.

This article traces the history of US Army physical fitness assessments from the first test developed for Cadets at the US Military Academy in 1858 through efforts to revise the current Army Physical Fitness Test (APFT). The first "Individual Efficiency Test" (1920) for all Soldiers consisted of a 100-yard run, running broad jump, wall climb, hand grenade throw, and obstacle course. The first scientific efforts involved testing of 400 Soldiers and a factor analysis of 25 individual test items. In 1944, this resulted in a 7-item test (pull-up, burpee, squat jump, push-up, man-carry, sit-up and 300-yard run) with a 100-point scoring system. In 1943, women were encouraged to take a "self-assessment" consisting of push-ups, bent knee sit-ups, wing lifts, squat thrusts, running, and a stork stand. In 1946, age-adjusted standards were introduced and in 1965 semiannual fitness assessments were mandated. The number of tests proliferated in the 1969-1973 period with 7 separate assessments. The current APFT consisting of push-ups, sit-ups, and a 2-mile run was introduced in 1980 and alternative tests for those with physical limitations in 1982. Current efforts to revise the assessment involve systematic literature reviews and validating the relationship between test items and common Soldiering tasks.

Background To determine whether the provision of higher levels of compulsory school physical activity is associated with higher physical activity and fitness levels and less overweight in childhood and 20 years later. Methods As part of the 1985 Australian Schools Health and Fitness Survey, 109 schools reported how much compulsory physical education (PE) and school sport they provided and were classified as low (compulsory physical activity schools by tertile cutpoints. 6,412 children reported frequency and duration of school (PE and sport) and non-school (commuting and non-organised exercise) physical activity and had height and weight measured; overweight was defined using body mass index (BMI) (m/kg2) cutpoints. 9, 12 and 15 year-olds (n = 2,595) completed a cycle ergometer fitness test (physical working capacity at heart rate 170, PWC170). At follow-up in 2004–5, 2,346 participants kept a pedometer record, completed the International Physical Activity Questionnaire and/or a PWC170 fitness test; and had height and weight measured (overweight = BMI≥25 m/kg2). Results At baseline and follow-up, median total physical activity, fitness and BMI were similar in participants who attended low, medium and high physical activity schools, and those attending high physical activity schools reported only modestly higher school physical activity. There was no difference in the prevalence of high total physical activity and fitness levels in childhood or adulthood across compulsory school physical activity categories. The prevalence of overweight in childhood and adulthood was similar across low, medium and high compulsory physical activity schools. Conclusion The amount of compulsory physical activity reported by schools was not associated with total physical activity, fitness or overweight in childhood or in adulthood. Policies promoting amounts of compulsory school physical activity in this range may not be sufficient to increase physical activity and fitness or reduce

A unique aspect of exercise is that people may choose to engage in it to achieve a variety of outcomes, ranging from extrinsic (appearance, health) to intrinsic (satisfaction, enjoyment). We examined how the impact of gain- vs. loss-framed messages depends on the type of outcome emphasised. Drawing from regulatory focus theory (Higgins, E.T. (1997). Beyond pleasure and pain. American Psychologist, 52, 1280-1300; Higgins, E.T. (2000). Making a good decision: Value from fit. American Psychologist, 55, 1217-1230), we predicted that gain-framed messages would 'fit' with intrinsic outcomes and loss-framed messages would 'fit' with extrinsic outcomes, but the effect of such fit on physical activity would depend on the participants' need for cognition (NC). We tested these hypotheses with a sample of 176 sedentary young adults who read an exercise message with randomly assigned frame (gain/loss) and outcome (intrinsic/extrinsic). Participants provided daily reports of exercise over the following week. The predicted interaction between frame, outcome and NC was found (p=0.001) such that a 'fit' message promoted somewhat, but not significantly, greater exercise for those with high NC, but a 'non-fit' message promoted significantly greater exercise for those with low NC. Furthermore, differences in physical activity were partially mediated by attitudes towards exercise. Findings shed light on how the outcomes and motivations associated with physical activity shape people's behavioural responses to framed health communications. © 2011 Taylor & Francis

No previous studies have investigated attitudes of the female soldiers toward physical fitness tests and physical performance requirements. The purpose of the present study was to investigate how military personnel group, age, physical fitness, and body composition are associated with female soldiers' attitudes toward fitness tests and requirements. A survey was conducted for 362 voluntary female soldiers. 76 % of them answered that the current fitness requirements are not too demanding, and 56 to 76% thought that the minimum requirements are at appropriate level for females. Nearly half (48%) of the female soldiers reported that it creates inequality when there are the same fitness standards for both genders. 12 % of the studied females had experienced bullying and 24% had experienced discrimination because of their physical fitness. Noncommissioned officers, older soldiers, overweight soldiers, and those with lower fitness thought more often that the physical fitness requirements are too high for female soldiers (p < 0.05). Lower fitness and overweight were associated with higher prevalence of being bullied and experiences of discrimination because of physical fitness (p < 0.05). The results suggest that there might be a need for a better communication about fitness requirements and targeted interventions for better integration of women in military environment.

Epidemiological studies often have to rely on a participant's self-reporting of information. The validity of the self-report instrument is an important consideration in any study. The purpose of this investigation was to determine the validity of self-reported Army Physical Fitness Test (APFT) scores. The APFT is administered to all soldiers in the U.S. Army twice a year and consists of the maximum number of push-ups completed in 2 minutes, the maximum number of sit-ups completed in 2 minutes, and a 2-mile run for time. Army mechanics responded to a questionnaire in March and June 2004 asking them to report the exact scores of each event on their most recent APFT. Actual APFT scores were obtained from the soldier's military unit. The mean +/- standard deviation (SD) of actual and self-reported numbers of push-ups was 61 +/- 14 and 65 +/- 13, respectively. The mean +/- SD of actual and self-reported numbers of sit-ups were 66 +/- 10 and 68 +/- 10, respectively. The mean +/- SD of actual and self-reported run times (minutes) were 14.8 +/- 1.4 and 14.6 +/- 1.4, respectively. Correlations between actual and self-reported push-ups, sit-ups, and run were 0.83, 0.71, and 0.85, respectively. On average, soldiers tended to slightly over-report performance on all APFT events and individual self-reported scores could vary widely from actual scores based on Bland-Altman plots. Despite this, the close correlations between the actual and self-reported scores suggest that self-reported values are adequate for most epidemiological military studies involving larger sample sizes.

Although low cardiorespiratory fitness (CRF), physical inactivity, and obesity are associated with impaired autonomic function, they are also extensively interrelated. The present study aimed to assess the extent to which they contribute to autonomic function independently of each other. At the age of 46 yr, 1383 men and 1761 women without cardiorespiratory diseases and diabetes underwent assessments of vagally mediated heart rate (HR) variability (root mean square of successive differences in R-R interval (rMMSD)), peak HR during a submaximal step test (CRF), and 60-s HR recovery (HRR). Moderate-to-vigorous physical activity (MVPA; ≥3.5 METs, 2 wk) was measured by wrist-worn accelerometer and body fat percentage (Fat%) by bioimpedance. In men, CRF and Fat% were significantly associated with higher rMSSD (standardized β = 0.31 and -0.16) and HRR (β = 0.19 and -0.18), whereas higher MVPA was linked with higher HRR (β = 0.13) when including CRF, MVPA, and Fat% in the initial regression. After adjustments for other lifestyle and cardiometabolic factors, CRF remained significantly associated with rMMSD (β = 0.24) and HRR (β = 0.14), as did MVPA with HRR (β = 0.11). In women, CRF was associated with rMSSD (β = 0.23) and HRR (β = 0.15), and MVPA (β = 0.17) and Fat% (β = -0.07) with HRR, when CRF, MVPA, and Fat% were adjusted for each other. After further adjustments, CRF remained a significant determinant of rMSSD (β = 0.20) and HRR (β = 0.13), as did MVPA with HRR (β = 0.15). The final models explained 23% and 21% of variation in rMSSD and HRR in men, and 10% and 12% in women, respectively. CRF was a more important determinant of cardiac autonomic function than MVPA and body fat. Furthermore, MVPA but not body fat was independently associated with cardiac autonomic function in both men and women.

The present study sought to quantify the relationships among physical activity (PA), health-related fitness, and motor skill in children (grades 4 to 6), and to determine whether specific tests of fitness or motor skill are independently associated with objectively measured PA level. Four hundred and ninety-one students (56.4% female) wore a Digi-Walker pedometer for 7 consecutive days. Standardized protocols were used to assess health-related fitness (body mass index percentile, waist circumference, 20-m shuttle run, plank, handgrip, and trunk flexibility). Motor skill was evaluated using a validated obstacle course. Pearson correlations (with Holm adjustments for multiple comparisons) initially assessed associations among PA, health-related fitness, and motor skill. Multi-variable linear regression was used to determine which factors were significantly associated with daily step counts, while adjusting for gender, age, testing season, and socioeconomic status. Step counts were significantly correlated with predicted aerobic power (r = 0.30), obstacle course time (r = -0.27), obstacle course score (r = 0.20), plank isometric torso endurance (r = 0.16), and handgrip strength (r = 0.12), but not with waist circumference (r = -0.10), trunk flexibility (r = 0.10), or overweight status (ρ = -0.06). In the multi-variable model, predicted aerobic power, obstacle course time, testing season, gender, and the predicted aerobic power by gender interaction were significantly associated with step counts, explaining 16.4% of the variance. Specifically, the relationship between predicted aerobic power and step counts was stronger in girls. These findings suggest that aerobic fitness and motor skill are independently associated with children's PA. Future longitudinal studies should evaluate whether interventions to enhance aerobic fitness and motor skill could enhance daily PA among children of this age.

This study's aims were to describe the development of physical activity, physical fitness (PF), subjective (physical complaints (PC)) and objective (Body mass index (BMI)) health measures and to examine the relationship between the development trajectories. In addition, the study also aimed to assess the influence of sociodemographic determinants (age, sex, socioeconomic status (SES)) in German adults over a period of 18 years. The longitudinal study population comprises of 721 men and women, aged 33-76 years over the study period. There was self-report of physical activity and PC and testing of physical fitness and BMI in each study year (1992, 1997, 2002 and 2010). Latent growth curve models were used to analyse the development. Physical activity slightly increased while fitness, PC and BMI worsened over the course of 18 years. Sex, age and SES play important roles concerning physical activity, fitness and health. Several integrative associations could be detected between physical activity, fitness, PC and BMI as well as their trajectories. In particular, high initial levels of physical activity and fitness protect from high PC and BMI.The slope of physical activity was not significantly associated with slopes of fitness, PC and BMI. However, increase of fitness resulted in decrease of PC. A general positive development regarding the amount of physical activity could be detected. However, if it is only an unsystematic increase of physical activity, this is not in itself enough to achieve health benefits. The strengthening of fitness should be focused when increasing physical activity, since only then a health benefit is possible.

Children's eating habits have mainly been related to anthropometric characteristics but less is known about their association with physical fitness. 278 French school children (131 boys and 147 girls) filled in eating habit questionnaires and completed anthropometric measurement (weight, height, skinfolds) and physical fitness tests. The 20-m Shuttle run test and the Squat Jump test were used to assess aerobic fitness and anaerobic (lower limb muscle power) fitness respectively. Breakfast consumption was associated with both aerobic fitness (peating habits was negatively associated with CRF stages and lower limb muscle power performances (peating habits and decreases with the number of unhealthy eating behaviors cumulated.

Although language is generally spoken, most evolutionary proposals say little about any changes that may have induced vocal control. Here I suggest that the interaction of two changes in our species-one in sociality, the other in life history-liberated the voice from its affective moorings, enabling it to serve as a fitness cue or signal. The modification of life history increased the helplessness of infants, thus their competition for care, pressuring them to emit, and parents (and others) to evaluate, new vocal cues in bids for attention. This change elaborated and formalized the care communication system that was used in infancy and, because of parental adoption of social criteria, extended it into childhood, supporting the extrafamilial relationships that intensify in those stages. The remodeling of life history, in conjunction with intensified sociality, also enhanced vocal signaling in adolescence-a second stage that is unique to humans-and adulthood. Building on the new vocal skills and fitness criteria that emerged earlier, I claim that males with ornamented speech enjoyed advantages in their pursuit of dominance and reproductive opportunities in evolutionary history, as they do today. There are implications of this scenario for the mechanistic level of vocal diversification. Today, intentionality plays a role both in the instrumental crying of infants and the modulated vocalizations of adults. In evolutionary history, I claim that in both cases, spontaneously emitted behavioral cues elicited perceptible responses, giving rise to strategic signals that were sent, and processed, under a new and fundamentally different neural regime.

Physical fitness seems to be related to academic performance, at least when taking the role of executive functioning into account. This assumption is highly relevant for the vulnerable population of low academic achievers because their academic performance might benefit from enhanced physical fitness. The current study examined whether physical fitness and executive functioning are independent predictors of low mathematics and spelling achievement or whether the relation between physical fitness and low achievement is mediated by specific executive functions. In total, 477 students from second- and third-grade classes of 12 primary schools were classified as either low or average-to-high achievers in mathematics and spelling based on their scores on standardized achievement tests. Multilevel structural equation models were built with direct paths between physical fitness and academic achievement and added indirect paths via components of executive functioning: inhibition, verbal working memory, visuospatial working memory, and shifting. Physical fitness was only indirectly related to low achievement via specific executive functions, depending on the academic domain involved. Verbal working memory was a mediator between physical fitness and low achievement in both domains, whereas visuospatial working memory had a mediating role only in mathematics. Physical fitness interventions aiming to improve low academic achievement, thus, could potentially be successful. The mediating effect of executive functioning suggests that these improvements in academic achievement will be preceded by enhanced executive functions, either verbal working memory (in spelling) or both verbal and visuospatial working memory (in mathematics).

Lower levels of physical activity and cardiorespiratory fitness are key risk factors of chronic adult diseases. Physical activity and cardiorespiratory fitness are predicted by birth weight, but the underlying parental and pregnancy-related factors remain largely unknown. We examined how prenatal determinants are associated with physical activity and cardiorespiratory fitness in adolescence. Of the 16-year-old members of the population-based Northern Finland Birth Cohort 1986 (NFBC 1986), 6682 singletons with no major physical disability reported their amount of physical activity outside school hours, and 4706 completed a submaximal cycle ergometer test assessing cardiorespiratory fitness. Physical activity was expressed as metabolic equivalent hours per week (METh/week) and cardiorespiratory fitness as peak oxygen uptake (ml·kg-1·min-1). Prenatal determinants included birth weight, length of gestation, mother's and father's body mass index (BMI), maternal gestational diabetes mellitus (GDM), and maternal hypertension and smoking during pregnancy. Data were analyzed by multiple linear regression. A higher birth weight and longer length of gestation predicted lower levels of physical activity and cardiorespiratory fitness at 16 years, although the association between length of gestation and physical activity was inverse U-shaped. Mother's or father's overweight or obesity before pregnancy were associated with lower levels of their offspring's physical activity and fitness in adolescence. Adjusting for maternal pregnancy disorders and the adolescent's own BMI attenuated the associations with the mother's but not the father's overweight/obesity. Furthermore, maternal GDM predicted lower cardiorespiratory fitness. A high birth weight and parental overweight/obesity are associated with lower levels of both physical activity and cardiorespiratory fitness in adolescence, while maternal GDM and longer length of gestation are associated with lower cardiorespiratory
Full Text Available Background: Health-related physical fitness components are important in hypokinetic disease prevention and good sports performance. The aim of this research is to evaluate the physical fitness profile of the SDN Cibeusi young football players based on Fitnessgram. Methods: This study was participated by 20 subjects ranging from 10 to 12 years old boys who played for the school football team in SDN Cibeusi. This descriptive study was conducted in the school field in the month of November 2012. Physical fitness components that were tested are aerobic capacity,V02 max using the one-mile run test, muscle endurance by performing push-up and curl-up test, flexibility using the flexometer and body composition by measuring the body mass index and fat fold measurement. The mean and standard deviation of the results were tabulated. Results: Aerobic capacity and percentage of body fat showed 100% of them scored in the category of healthy fitness zone. For body mass index, 55% scored in healthy fitness zone, 25% ni-some risk, and 10% each for ni-high risk and very lean. For push-up test and curl-up test, 80% and 65% scored in the healthy fitness zone while the remaining 20% and 35% respectively scored in the not healthy fitness zone. For flexibility, 75% of them scored in healthy fitness zone and 25% scored in not healthy fitness zone. Conclusions: The physical fitness level in these young football players is mostly in healthy fitness zone.

This review aims to summarize the latest developments with regard to physical fitness and several health outcomes in young people. The literature reviewed suggests that (1) cardiorespiratory fitness levels are associated with total and abdominal adiposity; (2) both cardiorespiratory and muscular fitness are shown to be associated with established and emerging cardiovascular disease risk factors; (3) improvements in muscular fitness and speed/agility, rather than cardiorespiratory fitness, seem to have a positive effect on skeletal health; (4) both cardiorespiratory and muscular fitness enhancements are recommended in pediatric cancer patients/survivors in order to attenuate fatigue and improve their quality of life; and (5) improvements in cardiorespiratory fitness have positive effects on depression, anxiety, mood status and self-esteem, and seem also to be associated with a higher academic performance. In conclusion, health promotion policies and physical activity programs should be designed to improve cardiorespiratory fitness, but also two other physical fitness components such us muscular fitness and speed/agility. Schools may play an important role by identifying children with low physical fitness and by promoting positive health behaviors such as encouraging children to be active, with special emphasis on the intensity of the activity.

Highly active antiretroviral therapy has significantly extended survival of human immunodeficiency virus (HIV) infected patients. These drugs suppress replication of HIV but at the same time, have many physical and mental side effects which may affect daily activities of the patients. The present study assessed if moderate intensity exercise program helped in enhancing the physical fitness and quality of life (QoL) in HIV positive females which may reduce the comorbidities associated with the disease and medications. The aim of this study is to study the effects of moderate intensity physical training on physical fitness parameters and QoL in HIV positive females. Post IEC approval, a randomized control, single-blinded, parallel group trial was conducted on 55 females (20 experimental HIV, 20 control HIV, 15 control normal) matching the selection criteria. Post informed consent, their muscular endurance, flexibility, aerobic capacity, and QoL was assessed. Moderate intensity physical exercises were given to experimental HIV and control normal 5 days/week for 8 weeks and subjects were reassessed for above parameters. Intragroup analysis was performed using paired t-test while inter-group was by one-way ANOVA with alpha set at ≤0.05. Moderate-intensity exercises improved muscular endurance (P fitness as well as enhance the QoL in HIV positive females.

Approximately 3.2 million people die of non-communicable diseases (NCD) each year due to insufficient physical activity. Physical activity guidelines are possibly perceived as too demanding and might thus pose a barrier. We addressed the question if a more stable physical activity pattern is associated with higher levels of health-related fitness than one with high and low intensities, regardless of the physical activity level (PAL). Physical activity was objectively measured in 296 men and women (53.7 ± 8.94 years) with the SenseWear Pro Armband(®). Using this data, the PAL and a Gini index were calculated to report the physical activity pattern. Health-related fitness was expressed as a fitness index. PAL was weakly correlated to health-related fitness (r = 0.38, P physical activity pattern or variability in intensities throughout the day.

Several findings revealed the importance of accruing moderate and vigorous physical activity (MVPA) to improve health. Physical education (PE) may play an important role on promoting children's MVPA. However, it remains unknown whether PE might be effective when increasing physical activity (PA) levels in children with lower cardiorespiratory fitness (CRF). Therefore, the aim of this study was to assess children's PA during PE and during days with and without PE with a special focus on CRF status. One hundred and fifty Spanish children and adolescents from 3rd to 12th grade were recruited. PA levels were assessed with GT3X accelerometers. Peak oxygen uptake (VO 2peak ) was estimated using a portable breath by breath Metamax 3B. Participants were classified as healthy aerobic fitness (HAF) and unhealthy aerobic fitness (UHAF) according to standardized cut-off point criteria. During PE, students with HAF accrued more MVPA than those with UHAF (8.7 vs 5.7 min/session; P ≤ 0.001). MVPA was higher on PE days than days without for both UHAF (50.0 vs 42.7 min/day; P ≤ 0.05) and HAF students (56.9 vs 49.4 min/day; P ≤ 0.05). Although less active during PE, students with lower CRF accumulated more MVPA and total PA on PE days than days without PE. An increase in PE days might be a smart policy to raise the recommended PA levels, regardless of CRF status. © 2016 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

Physicists study a wide variety of phenomena creating new interdisciplinary research fields by applying theories and methods originally developed in physics in order to solve problems in economics, social science, biology, medicine, technology, etc. In their turn, these different branches of science inspire the invention of new concepts in physics. A basic tool of analysis, in such a context, is the mathematical theory of complexity concerned with the study of complex systems including human economies, climate, nervous systems, cells and living things, including human beings, as well as modern energy or communication infrastructures which are all networks of some kind. Recently, complexity has become a natural domain of interest of the real world socio-cognitive systems, linguistics, and emerging systemics research. The phenomena to be studied and understood arise from neither the physical laws nor the abstraction of mathematics. The challenge is to discern and formulate plausible mathematical structures to d...

This article presents the results of research based on the feelings and responses of members of a sports club, in relation to a fitness programme offered by Fitness World. The study consisted of a group of 58 participants chosen at random. Statistically, the analysed results of the research show that the biggest group attending Fitness World consists of men between 31 and 50 years of age with higher education, and women between 18 and 30 with, mostly, higher education. In general, men prefer to participate in aerobics group sessions and gym sessions, and women choose to take part in any activities. The most preferred time was between 5 p.m. and 10 p.m., usually after work, and with a frequency of twice a week. It was not possible to determine the main reasons for motivation, although 93% prefer to practise regularly.

The U.S. Army Basic Combat Training (BCT) is the first step in preparing soldier trainees for the physical demands of the military. Unfortunately, a substantial number of trainees fail BCT due to failure on the final Army Physical Fitness Test (also known as the "end of cycle" APFT). Current epidemiological studies have used statistics to identify several risk factors for poor APFT performance, but these studies have had limited utility for guiding regimen design to maximize APFT outcome. This is because such studies focus on intrinsic risks to APFT failure and do not utilize detailed BCT activity data to build models which offer guidance for optimizing the training regimen to improve graduation rates. In this study, a phenomenological run performance model that accounts for physiological changes in fitness and fatigue due to training was applied to recruits undergoing U.S. Army BCT using high resolution (minute-by-minute) activity data. The phenomenological model was better at predicting both the final as well as intermediate APFTs (R(2) range = 0.55-0.59) compared to linear regression models (LRMs) that used the same intrinsic input variables (R(2) range = 0.36-0.50). Unlike a statistical approach, a phenomenological model accounts for physiological changes and, therefore, has the potential to not only identify trainees at risk of failing BCT on novel training regimens, but offer guidance to regimen planners on how to change the regimen for maximizing physical performance. This paper is Part I of a 2-part series on physical training outcome predictions. Reprint & Copyright © 2016 Association of Military Surgeons of the U.S.

We aimed (1) to report age-specific physical fitness levels in people with fibromyalgia of a representative sample from Andalusia; and (2) to compare the fitness levels of people with fibromyalgia with non-fibromyalgia controls. This cross-sectional study included 468 (21 men) patients with fibromyalgia and 360 (55 men) controls. The fibromyalgia sample was geographically representative from southern Spain. Physical fitness was assessed with the Senior Fitness Test battery plus the handgrip test. We applied the Generalized Additive Model for Location, Scale and Shape to calculate percentile curves for women and fitted mean curves using a linear regression for men. Our results show that people with fibromyalgia reached worse performance in all fitness tests than controls (P fitness levels among patients with fibromyalgia and controls in a large sample of patients with fibromyalgia from southern of Spain. Physical fitness levels of people with fibromyalgia from Andalusia are very low in comparison with age-matched healthy controls.

This study aimed to examine the associations between objectively measured physical activity (PA), sedentary time, and health-related fitness and to investigate the combined association of PA and sedentary time on health-related fitness in youths. PA and sedentary time were assessed with accelerometers in 2506 youths age 10-18 yr (M(age) = 13.2 ± 2.3). Participants were classified as active (≥60 min·d(-1) of moderate-to-vigorous physical activity (MVPA)) versus inactive (low sedentary" versus "high sedentary" (according to the median value of sedentary time per day) and thereafter grouped as active/low sedentary, active/high sedentary, inactive/low sedentary, and inactive/high sedentary. Five physical fitness tests (body mass index, push-ups, curl-ups, sit and reach, and the Progressive Aerobic Cardiovascular Endurance Run test) were assessed with FITNESSGRAM, and participants were categorized as being in the healthy fitness zone (HFZ) versus the unhealthy fitness zone. A fitness composite score was calculated using the individual fitness test z-score. Regression models were used to examine the relation between PA, sedentary time, and physical fitness. Time spent in MVPA (min·d(-1)) (β = 0.002, P low sedentary was associated with increased likelihood of being in the HFZ for sit and reach (odds ratio, 2.55; 95% confidence interval, 1.96-3.32) and having a higher fitness composite score (odds ratio, 1.38; 95% confidence interval, 1.13-1.69). Time in MVPA was associated with better physical fitness independent of sedentary time. Participants classified as active/low sedentary had higher odds of being in the HFZ, for flexibility, and to have a better fitness composite score. These findings suggest that time in MVPA contributes to better physical fitness in youths.

Negative associations between physical activity (PA), physical fitness and multiple metabolic risk factors (MMRF) in youths from populations with low PA are reported. The persistence of this association in moderately-to highly active populations is not, however, well established. The aim of the present study was to investigate this association in a Brazilian city with high frequency of active youths. We assessed 122 subjects (9.9 ± 1.3 years) from Muzambinho city. Body mass index, waist circumference, glycaemia, cholesterolaemia, systolic and diastolic blood pressures were measured. Maximal handgrip strength and one-mile walk/run test were used. Leisure time PA was assessed by interview. Poisson regression was used in the analysis. The model explained 11% of the total variance. Only relative muscular strength and one-mile walk/run were statistically significant (p run test had an increased in metabolic risk of 11%, and those with greater strength reduced the risk by about 82%. In conclusion, children and youths from an active population who need less time to cover the one-mile walk/run test or who had greater muscular strength showed a reduced metabolic risk. These results suggest that even in children and youths with high leisure time PA, a greater aerobic fitness and strength might help to further reduce their MMRF.

The Self-determined Exercise and Learning For FITness (SELF-FIT) is a multi-component school-based intervention based on tenets of self-determination theory. SELF-FIT aims to increase students' moderate-to-vigorous physical activity (MVPA) during physical education lessons, and enhance their autonomous motivation towards fitness activities. Using a cluster randomized controlled trial, we aim to examine the effects of the intervention on students' MVPA during school physical education. Secondary 2 students (approximately aged 14 years) from 26 classes in 26 different schools will be recruited. After baseline assessments, students will be randomized into either the experimental group or wait-list control group using a matched-pair randomization. Teachers allocated to the experimental group will attend two half-day workshops and deliver the SELF-FIT intervention for 8 weeks. The main intervention components include training teachers to teach in more need supportive ways, and conducting fitness exercises using a fitness dice with interchangeable faces. Other motivational components, such as playing music during classes, are also included. The primary outcome of the trial is students' MVPA during PE lessons. Secondary outcomes include students' leisure-time MVPA, perceived need support from teachers, need satisfaction, autonomous motivation towards physical education, intention to engage in physical activity, psychological well-being, and health-related fitness (cardiorespiratory and muscular fitness). Quantitative data will be analyzed using multilevel modeling approaches. Focus group interviews will also be conducted to assess students' perceptions of the intervention. The SELF-FIT intervention has been designed to improve students' health and well-being by using high-intensity activities in classes delivered by teachers who have been trained to be autonomy needs supportive. If successful, scalable interventions based on SELF-FIT could be applied in physical

The purpose of this study was to look at the effect of additional individual physical training (PT) in addition to mandatory unit PT as well as other risk factors on physical fitness. A cross-sectional design. This study was conducted on a US military installation. Participants were 6290 male and 558 female active duty US Army soldiers in 3 light infantry brigades. Participants completed self-administered questionnaires asking about individual characteristics, PT, and physical fitness. Cut points were established for soldiers scoring within the top 33% for each of the 3 Army Physical Fitness Test events (2-mile run, sit-ups, and push-ups) and top 50% in each of the tests combined for overall performance. Odds ratios and 95% confidence intervals from multivariate analyses were calculated. Variables impacting physical fitness performance of men and women included increased body mass index, leading unit PT sessions, and individual distance running mileage. Other variables impacting physical performance for men included increased age, smoking, and individual resistance training. Soldiers performing additional individual PT demonstrated a positive influence on fitness compared to unit PT participation alone. Increased age and being overweight/obese negatively influenced physical fitness. To enhance fitness performance through unit PT, running by ability groups and resistance training should be encouraged by leadership.

Physical fitness at young adult ages is an important determinant of physical health, cognitive ability, and mortality. However, few studies have addressed the relationship between early life conditions and physical fitness in adulthood. An important potential factor influencing physical fitness is birth order, which prior studies associate with several early- and later-life outcomes such as height and mortality. This is the first study to analyse the association between birth order and physical fitness in late adolescence. We use military conscription data on 218,873 Swedish males born between 1965 and 1977. Physical fitness is measured by a test of maximal working capacity, a measure of cardiovascular fitness closely related to V02max. We use linear regression with sibling fixed effects, meaning a within-family comparison, to eliminate the confounding influence of unobserved factors that vary between siblings. To understand the mechanism we further analyse whether the association between birth order and physical fitness varies by sibship size, parental socioeconomic status, birth cohort or length of the birth interval. We find a strong, negative and monotonic relationship between birth order and physical fitness. For example, third-born children have a maximal working capacity approximately 0.1 (p birth order effect does not depend on the length of the birth intervals, in two-child families a longer birth interval strengthens the advantage of the first-born. Our results illustrate the importance of birth order for physical fitness, and suggest that the first-born advantage already arises in late adolescence. Copyright © 2014 Elsevier Ltd.

The aim of the present study was to quantify the relation between physical fitness and oral function, including tongue and lip movements. Physical fitness and oral function influence quality of life and activities of daily living in older individuals. Occlusal contact and mastication performance are associated with physical fitness, but the association between tongue and lip movements and physical fitness is unclear. Sixty-six independent community-dwelling older individuals (24 men, 42 women; mean age, 70.3 ± 5.9 years) participated in this study. Measures of physical fitness were the one-leg standing time with eyes open, the functional reach test, anteflexion, the timed up and go test, and grip strength. Measures of oral function were tongue pressure, lip pressure, tongue movement from side to side, the repetitive saliva-swallowing test (RSST), oral diadochokinesis and masticatory efficiency. Multiple regression analysis was used to quantify the relation between physical fitness and oral function. After adjustment for age, sex, BMI, exercise habits and number of remaining teeth, the tongue movement from side to side and/or oral diadochokinesis were chosen as significant factors in each physical fitness measurement. Furthermore, the lip pressure and masticatory efficiency were associated with handgrip strength. Oral function, including tongue and lip movements, was associated with physical fitness in older people in this study. Tongue dexterity as characterised by tongue movement from side to side and oral diadochokinesis particularly associated with physical fitness. © 2015 John Wiley & Sons A/S and The Gerodontology Association.

Research on physical fitness often regards socioeconomic status (SES) as a confounding factor. However, few studies investigate the impact of SES on fitness. This study investigated the impact of SES on physical fitness in both males and females, with an economic-based construct of SES. The sample consisted of 954 6th, 7th, and 8th graders from a public, urban, Illinois middle school. The students participated in the FITNESSGRAM battery of fitness assessments as part of physical education. Descriptive statistics were calculated for height, weight, age, and sex. Students were grouped as high or low SES depending on whether they qualified for the federal free lunch program. A multivariate analysis of variance controlled for age and stratified by sex compared the raw scores from the fitness test for low and high SES students. Odds ratios stratified by sex were calculated for the likelihood of not achieving the FITNESSGRAM Healthy Fitness Zone standards among SES groups. Girls of the low SES group had significantly lower scores on the FITNESSGRAM assessments and were significantly less likely to achieve Healthy Fitness Zone status than the girls from the high SES groups. For boys, SES was a significant main effect for body composition but not for the other fitness tests conducted. SES is related to physical fitness in girls but not in boys. A potential explanation for this is that boys are more likely to engage in vigorous leisure time activity regardless of SES than girls. © 2013, American School Health Association.

The purpose of this study was to perform a construct validity assessment of Kendzierski's exercise self-schema theory questionnaire using objective measures of health-related physical fitness. This study tested the hypothesis that individuals with an exercise self-schema would possess significantly greater physical fitness than those who did not across three domains of health-related physical fitness: Body composition, cardiovascular fitness, and upper-body muscular endurance. Undergraduate student participants from one private university on the west coast of the United States completed informed consent forms and the exercise self-schema questionnaire within a classroom setting or at an on-campus outside tabling session. Participants not meeting inclusion criteria for Kendzierski's three original schema groups were categorized as "unschematic," and were included within MANCOVA/ANCOVA analyses, where gender served as the covariate. Participants underwent lab-based fitness assessments administered in accordance with the 2013 American College of Sports Medicine Guidelines for Exercise Testing and Prescription. The hypothesis of this study was partially supported. Specifically, exerciser schematics were significantly leaner than aschematics (p = .002) and they had greater levels of upper-body muscular endurance compared to both aschematic and nonexerciser schematics (p = .002). However, no differences were observed for cardiovascular fitness (i.e., predicted V02Max p = .410). The findings of this study help to establish the construct validity of Kendizerski's self-report exercise self-schema categorization scheme. Visual inspection of the data, as well as computed effect size measures suggest exercise self-schema is associated with dimensions of one's physical fitness.

Abstract A positive relationship between daily physical activity and aerobic fitness exists in adults. Studies in children have given conflicting results, possibly because of differences in methods used to assess daily physical activity and fitness. No study regarding daily physical activity...... and fitness in children has been published, where fitness has been assessed by direct measurement of maximum oxygen uptake and related to daily physical activity intensities by accelerometers. We examined 248 children (140 boys and 108 girls), aged 7.9-11.1 years. Maximum workload and maximal oxygen uptake...... (VO2PEAK) by indirect calorimetry were measured during a maximum bicycle ergometer exercise test. Exercise capacity was adjusted for body mass and (body mass)2/3. Daily physical activity was evaluated by accelerometers, worn around the waist for 4 days. Mean accelerometer counts and time spent...

Fatigue is a common and distressing post stroke symptom. One important hypothesis is that fatigue after stroke may be triggered by physical deconditioning, which sets up a vicious, self-perpetuating cycle of fatigue, avoidance of physical activity, further deconditioning, and more fatigue. If an association between physical activity and fatigue after stroke could be established, this would provide a rationale for developing a physical activity-based treatment. Systematically review all observational studies, which have measured both fatigue poststroke and one or more measures of physical fitness and/or physical activity at the same time-point and reported the association between fatigue and fitness variables. Publications were identified by systematically searching databases MEDLINE, EMBASE, CINAHL, PsychInfo, and Sportdiscus using keywords 'fatigue', 'stroke', 'fitness', or 'activity' and their associated terms or synonyms. Publications that provided data on associations between fatigue in stroke patients and levels of physical activity, cardiorespiratory fitness and/or muscle strength and mass were included. Twenty-nine potential studies were retrieved after scrutinizing the titles and abstracts, of which only three fulfilled our inclusion criteria. No association between fatigue and any measures of physical activity or fitness were found. One study did find, through structural equation modeling techniques that fatigue indirectly influences exercise through self-efficacy expectations. There is very limited evidence regarding associations between exercise, fitness, and fatigue after stroke. It still remains highly plausible that exercise can have a positive influence on fatigue. Future research should be longitudinal in design.

Physical fitness is an important correlate of structural and functional integrity of the brain in healthy adults. In heart failure (HF) patients, poor physical fitness may contribute to cognitive dysfunction and we examined the unique contribution of physical fitness to brain structural integrity among patients with HF. Sixty-nine HF patients performed the Modified Mini Mental State examination (3MS) and underwent brain magnetic resonance imaging. All participants completed the 2-minute step test (2MST), a brief measure of physical fitness. We examined the associations between cognitive performance, physical fitness, and three indices of global brain integrity: total cortical gray matter volume, total white matter volume, and whole brain cortical thickness. Regression analyses adjusting for demographic characteristics, medical variables (e.g., left ventricular ejection fraction), and intracranial volume revealed reduced performance on the 2MST were associated with decreased gray matter volume and thinner cortex (passociated with poorer 3MS scores (pphysical fitness is common in HF and associated with reduced structural brain integrity. Prospective studies are needed to elucidate underlying mechanisms for the influence of physical fitness on brain health in HF. Copyright © 2013 Elsevier B.V. All rights reserved.

Level of physical fitness is related to the functional status of most of the bodily functions and so it appears to be very important to identify perinatal factors influencing physical fitness. The purpose of this study was to determine the influence of birth weight on the level of physical fitness in children 6-7years of age. Physical fitness was assessed using EUROFIT tests in 28,623 children, aged 6-7years, from rural areas in Poland. Children below the 10th percentile for birth weight for gestational age were defined as small for gestational age (SGA). The influence of birth weight on parameters of fitness was assessed by means of covariance analysis. With the controls of age, sex and body size, children of low birth weight have shown significantly lower levels of body flexibility and running speed. The leg strength of children with SGA turned out to be significantly lower only in 7-year-old boys. This study has revealed the significant influence of birth weight on physical fitness. The results suggest the importance of early intervention and its possible benefits for developing and maintaining the proper level of physical fitness further in life. Copyright © 2017.

The aim of this study was to determine the association of levels of physical activity (PA), physical fitness (PF), sedentary lifestyle and life satisfaction with the intention to be physically active after secondary school graduation, in teenagers of both genders. A total of 1986 Spanish adolescents (12-16 years) participated in this cross-sectional study. PA, sedentary lifestyle, life satisfaction and intention to be physically active were assessed through validated questionnaires, and PF was evaluated objectively with the ALPHA battery tests. In both genders, adolescents who had significantly higher odds ratios (OR) of showing low intention to be physically active had low level of PA, cardiorespiratory fitness and muscular fitness in the lower body, and they were more sedentary in front of the computer. The girls that spent a lot of time watching TV and the boys with low life satisfaction also showed higher OR of having low intention to be physically active.

Full Text Available The prevalence of cardiovascular disease (CVD is increasing around the globe and is the leading cause of death around the world. Though once thought of as an adult problem, it is now recognised that the early manifestations of disease may occur during childhood. Numerous risk factors have been linked to CVD with much of the research focusing on understanding the prevalence and relationship of traditional risk factors such as dyslipidemia, smoking, diabetes mellitus, hypertension, obesity, psychosocial stress, poor diet, physical inactivity and alcohol consumption to the early etiology of disease. While this line of investigation has greatly enhanced our understanding of the relationship between these risk factors and disease, they do not fully explain all cardiovascular events. To enhance our understanding and help with the management of CVD, investigations that involve the measurement of traditional as well as novel risk factors may be necessary. Public health strategies that aim to reduce the prevalence of obesity and overweight encourage youth to increase their physical activity levels as a means of protecting against poor cardiometabolic profiles. Interventions that increase physical activity levels and improve cardiorespiratory fitness cause a reduction in certain CVD risk factors but the lack of agreement between findings makes it impossible to give precise recommendations that will ensure CVD risk reduction. Yet it is important that research continues in order to establish the most appropriate means of improving the health and well-being of those at most risk of future CVD.

We measured body composition and handgrip strength in 233 children and adolescents (10 - 17 years-old, who varied in terms of pubertal status. The subjects also performed the vertical jump test, standing long jump and sit-ups, as well as tests of flexibility, agility and speed. The level of energy expenditure was assessed with the international physical activity questionnaire. Handgrip strength differed by pubertal status, regardless of gender, whereas other parameters of physical fitness differed by gender and in the sample as a whole. Handgrip strength was consistently and independently associated with all other physical fitness variables, regardless of gender; some of those were mediated by energy expenditure (i.e., speed in seconds and in meters per second for the sample as a whole. The strength of the association between handgrip strength and physical fitness ranged from 20% (vertical jump test: R2=.20; P=.001 to 47% (speed in meters per second: R2=.47; P=.001. Our results support the idea that handgrip strength is consistently associated with several distinct parameters of physical fitness, regardless of age, gender or sexual maturation, suggesting that handgrip strength could be a highly accurate, independent predictor of physical fitness.

Introduction The influence of physical activity (PA) and physical fitness (PF) at older ages on changes in telomere length (TL), repetitive DNA sequences that may mark biologic aging, is not well-established. Few prior studies have been conducted in older adults, these were mainly cross-sectional, and few evaluated PF. Methods We investigated cross-sectional and prospective associations of PA and PF with leukocyte TL among 582 older adults (age 73±5 y at baseline) in the Cardiovascular Health Study, having serial TL measures and PA and PF assessed multiple times. Cross-sectional associations were assessed using multivariable repeated-measures regression, in which cumulatively averaged PA and PF measures were related to TL. Longitudinal analyses assessed cumulatively averaged PA and PF against later changes in TL; and changes in cumulatively averaged PA and PF against changes in TL. Results Cross-sectionally, greater walking distance and chair test performance, but not other PA and PF measures, were each associated with longer TL (p-trend=0.007, 0.04 respectively). In longitudinal analyses, no significant associations of baseline PA and PF with change in TL were observed. In contrast, changes in leisure-time activity and chair test performance were each inversely associated with changes in TL. Conclusions Cross-sectional analyses suggest that greater PA and PF are associated with longer TL. Prospective analyses show that changes in PA and PF are associated with differences in changes in TL. Even later in life, changes in certain PA and PF measures are associated with changes in TL, suggesting that leisure-time activity and fitness could reduce leukocyte telomere attrition among older adults.

The preschool years are characterized by the learning of combinations of movements that make it possible for children to attain an astonishingly high level of physical performance. With regard to their metabolism and cardiovascular/cardiopulmonary system, they have at their disposal good prerequisites for aerobic endurance training. However, it is a matter of the natural movements involved in playing rather than striving to reach a high level of performance. Sports during the preschool age advances physical development and serves as a form of early prevention of the diseases of civilization.

The purpose of this study was to evaluate the effects of creative dance on physical fitness and life satisfaction in older women. A total of 57 women (65-80 years old) were randomized to either an experimental group or a control group. The experimental group participated in a supervised creative dance program for 24 weeks. Physical fitness (strength, aerobic endurance, flexibility, motor ability/dynamic balance, and body composition) and life satisfaction were assessed pre- and posttreatment (at 12 and 24 weeks) by the Senior Fitness Test and the Life Satisfaction scale, respectively. After the intervention, the experimental group had better physical fitness and life satisfaction when compared with the control group. Creative dance has a positive effect in different dimensions of functioning and has the potential to contribute to healthy aging. This could be related to the integrated mobilization of physical, cognitive, and social skills promoted by creative dance. © The Author(s) 2015.

In real-world auditory environments, humans are exposed to overlapping auditory information such as those made by human voices and musical instruments even during routine physical activities such as walking and cycling. The present study investigated how concurrent physical exercise affects performance of incidental and intentional learning of overlapping auditory streams, and whether physical fitness modulates the performances of learning. Participants were grouped with 11 participants with lower and higher fitness each, based on their Vo2max value. They were presented simultaneous auditory sequences with a distinct statistical regularity each other (i.e. statistical learning), while they were pedaling on the bike and seating on a bike at rest. In experiment 1, they were instructed to attend to one of the two sequences and ignore to the other sequence. In experiment 2, they were instructed to attend to both of the two sequences. After exposure to the sequences, learning effects were evaluated by familiarity test. In the experiment 1, performance of statistical learning of ignored sequences during concurrent pedaling could be higher in the participants with high than low physical fitness, whereas in attended sequence, there was no significant difference in performance of statistical learning between high than low physical fitness. Furthermore, there was no significant effect of physical fitness on learning while resting. In the experiment 2, the both participants with high and low physical fitness could perform intentional statistical learning of two simultaneous sequences in the both exercise and rest sessions. The improvement in physical fitness might facilitate incidental but not intentional statistical learning of simultaneous auditory sequences during concurrent physical exercise.

MSc. programs are now widely used as part of the training and education of medical physicists. There is however paucity of data on the effectiveness of such courses and the purpose of the study reported here is to provide information on one particular MSc. course in medical physics. This is relevant to medical physicists who are involved in the development and running of medical physics training programs. The study used as methodology the Kirkpatrick levels of professional training. It was conducted through an online survey, both from students who graduated from the course and from students who were in the process of completing the course. The survey proved to be an effective way to determine attributes of modules such as learning outcomes, knowledge imparted, quality of teaching materials and others. The survey proved to be remarkably able to demonstrate interventions in the individual course modules. Although the course was shown to be effective in the imparting of the knowledge required to become a qualified medical physicist several areas for improvement were identified. These are mainly in the areas of increased practical experience and in course delivery.

To investigate the joint association between self-reported physical activity as well as cardiorespiratory fitness and self-rated health among healthy women and men. Data from 10,416 participants in The Danish Health Examination Survey 2007-2008 which took part in 13 Danish municipalities were analyzed. Leisure time physical activity level and self-rated health were based on self-reported questionnaire data. Optimal self-rated health was defined as "very good" or "good" self-rated health. Cardiorespiratory fitness (mL O2·min(-1)·kg(-1)) was estimated from maximal power output in a maximal cycle exercise test. A strong dose-response relation between cardiorespiratory fitness and self-rated health as well as between physical activity level and self-rated health among both women and men was found. Within categories of physical activity, odds ratios for optimal self-rated health increased with increasing categories of cardiorespiratory fitness, and vice versa. Hence, participants who were moderately/vigorously physically active and had a high cardiorespiratory fitness had the highest odds ratio for optimal self-rated health compared with sedentary participants with low cardiorespiratory fitness (odds ratio=12.2, 95% confidence interval: 9.3-16.1). Although reluctant to conclude on causality, this study suggests that an active lifestyle as well as good cardiorespiratory fitness probably increase self-rated health. © 2013.

This study tested the effectiveness of a multifaceted intervention that integrated childcare center, families, and community to promote healthy growth and physical fitness in preschool Chinese children. This 12-month study was conducted using a quasi-experimental pretest/posttest design with comparison group. The participants were 357 children (mean age = 4.5 year) enrolled in three grade levels in two childcare centers in Beijing, China. The intervention included: 1) childcare center intervention (physical activity policy changes, teacher training, physical education curriculum and food services training), 2) family intervention (parent education, internet website for support, and family events), and 3) community intervention (playground renovation and community health promotion events). The study outcome measures included body composition (percent body fat, fat mass, and muscle mass), Body Mass Index (BMI) and BMI z-score and physical fitness scores in 20-meter agility run (20M-AR), broad jump for distance (BJ), timed 10-jumps, tennis ball throwing (TBT), sit and reach (SR), balance beam walk (BBW), 20-meter crawl (20M-C)), 30-meter sprint (30M-S)) from a norm referenced test. Measures of process evaluation included monitoring of children's physical activity (activity time and intensity) and food preparation records, and fidelity of intervention protocol implementation. Children in the intervention center significantly lowered their body fat percent (-1.2%, p BBW: -2.02 seconds, p <0.0001; 30M-S: -0.45 seconds, p < 0.02; 20M-C: -3.36 seconds, p < 0.0001). Process evaluation data showed that the intervention protocol was implemented with high fidelity. The study demonstrated that a policy-driven multi-faceted intervention can improve preschool children's body composition and physical fitness. Program efficacy should be

Studies of the effects of physical fitness on cognition suggest that exercise can improve cognitive abilities in healthy older adults, as well as delay the onset of age-related cognitive decline. The mechanisms for the positive benefit of exercise and how these effects interact with other variables known to influence cognitive function (e.g., involvement in cognitive activities) are less well understood. The current study examined the associations between the physical fitness, cerebrovascul...

The aim of the 'Motorik-Modul' (MoMo Basiserhebung, www.motorik-modul.de ) was to establish prevalence measurements on physical fitness and physical activity in German children and adolescents and to identify differences between age groups and genders. A total of 4,529 children and adolescents between the ages of 4-17 years from 167 cities across all states of the German Federation participated in this study. Sociodemographic parameters were recorded. Physical fitness was measured using endurance, strength, coordination and flexibility tests. Physical activity was assessed using a validated questionnaire, including aspects of physical activity participation (school/club/non-club), intensity of physical activity and type of activity. Chi-square tests and ANOVAS were used to compare groups and to detect age and gender effects, and data were compared with criterion-related guidelines by the WHO. For parameters describing physical fitness, age was the dominant influencing parameter. Many parameters showed increasing performance until the onset of puberty. Boys generally performed better than girls except in fine motor coordination during precision tasks and in flexibility. Physical activity was greater in older subjects with a greater intensity for adolescents who were physically active. The general activity level was similar to the data reported in the HBSC study by the WHO but lower than the recommended activity levels. With the results of this study, nationwide representative prevalence data on physical fitness and physical activity are available. These data contribute to the scientific knowledge on the prevalence and conditions of physical fitness and physical activity.

This study investigated the influence of physical education class (PEC) as an intervention method for aggression, sociality, stress, and physical fitness levels in children from multicultural families. The hypothesis was that participating in PEC would result in reduced aggression and stress and improved sociality and physical fitness in multicultural children. A three-item questionnaire, a body composition test, and physical fitness tests were given three times. Eighty-four subjects were divided into four groups: multicultural children who participated in PEC (multi-PEG, n=12), multicultural children who did not participate in PEC (multi-NPEG, n=13), single-cultural children who participated in PEC (sing-PEG, n=11), and single-cultural children who did not participate in PEC (sing-NPEG, n=12), respectively. Parametric and nonparametric statistical methods were conducted on the collected data with a significance level set a priori at Pmulticultural families can improve psychosocial factors and physical health.

Foundations and governments fund a number of programs that provide grants to improve school physical education or other forms of school-based physical activity. The effects of these grant programs are unknown. We evaluate the effects of Texas Fitness Now, a program in which the state of Texas granted $37 million to improve physical education in high-poverty middle schools over the 4 school years from 2007-08 to 2010-11. The stated goals of Texas Fitness Now were to reduce obesity, increase fitness, and raise academic achievement. We summarize how Texas Fitness Now funds were spent and estimate the impact of Texas Fitness Now using a fixed-effects longitudinal model that exploits changes in schools' eligibility over time. Changes in eligibility occurred when eligibility expanded to new schools after year 2 and when the program was terminated after year 4. Most Texas Fitness Now funds were spent on sports and fitness equipment. Smaller amounts were spent on anti-obesity curricula. Texas Fitness Now improved strength and flexibility, especially among girls, but it did not improve BMI or academic achievement, and it had mixed effects on aerobic capacity. The fitness benefits were not lost in the year after the program ended, perhaps because schools kept the equipment that they had bought during their years of eligibility. The results of Texas Fitness Now were typical for an intervention that relied almost exclusively on physical activity. Programs that improve BMI as well as fitness tend to have a more fully developed nutrition component. Copyright © 2015 Elsevier Inc. All rights reserved.

Recruits arriving for basic combat training (BCT) between October 1999 and May 2004 were administered an entry-level physical fitness test at the reception station. If they failed the test, then they entered the Fitness Assessment Program (FAP), where they physically trained until they passed the test and subsequently entered BCT. The effectiveness of the FAP was evaluated by examining fitness, injury, and training outcomes. Recruits who failed the test, trained in the FAP, and entered BCT after passing the test were designated the preconditioning (PC) group (64 men and 94 women). Recruits who failed the test but were allowed to enter BCT without going into the FAP were called the no preconditioning (NPC) group (32 men and 73 women). Recruits who passed the test and directly entered BCT were designated the no need of preconditioning (NNPC) group (1,078 men and 731 women). Army Physical Fitness Test (APFT) scores and training outcomes were obtained from a company-level database, and injured recruits were identified from cases documented in medical records. The proportions of NPC, PC, and NNPC recruits who completed the 9-week BCT cycle were 59%, 83%, and 87% for men (p APFT, compared with 84% and 86% of the PC and NNPC groups, respectively. The proportions of NPC, PC, and NNPC recruits who passed the final APFT after all retakes were 88%, 92%, and 98% for men (p < 0.01) and 89%, 92%, and 97% for women (p < 0.01), respectively. Compared with NNPC men, injury risk was 1.5 (95% confidence interval, 1.0-2.2) and 1.7 (95% confidence interval, 1.0-3.1) times higher for PC and NPC men, respectively. Compared with NNPC women, injury risk was 1.2 (95% confidence interval, 0.9-1.6) and 1.5 (95% confidence interval, 1.1-2.1) times higher for PC and NPC women, respectively. This program evaluation showed that low-fit recruits who preconditioned before BCT had reduced attrition and tended to have lower injury risk, compared with recruits of similar low fitness who did not

Abstract Objective: The aim of this review is to synthesize the evidence on the effects of aquatic exercise interventions on physical function and fitness among people with spinal cord injury. Data source: Six major databases were searched from inception till June 2015: MEDLINE, CINAHL, EMBASE, PsychInfo, SPORTDiscus, and Cochrane Center Register of Controlled Trials. Study appraisal and synthesis methods: Two reviewers independently rated methodological quality using the modified Downs and Black Scale and extracted and synthesized key findings (i.e., participant characteristics, study design, physical function and fitness outcomes, and adverse events). Results: Eight of 276 studies met the inclusion criteria, of which none showed high research quality. Four studies assessed physical function outcomes and 4 studies evaluated aerobic fitness as outcome measures. Significant improvements on these 2 outcomes were generally found. Other physical or fitness outcomes including body composition, muscular strength, and balance were rarely reported. Conclusions and implications of key findings: There is weak evidence supporting aquatic exercise training to improve physical function and aerobic fitness among adults with spinal cord injury. Suggestions for future research include reporting details of exercise interventions, evaluating other physical or fitness outcomes, and improving methodological quality. PMID:28296754
Full Text Available BACKGROUND: Aerobic exercise reduces body fat and improves weight control, increases HDL&Vo2 max. Also improves PFI (physical fitness index which is defined as ability to carry out daily tasks with vigour and alertness without undue fatigue. Though aerobic exercise is found to improve physical fitness, the relative merits of different intensities of aerobi c exercise in improving physical fitness is still uncertain. AIM: The present study was conducted to know the Effect of High & low intensity aerobic training on physical fitness index. MATERIALS & METHODS : 80 sedentary men (18 - 40 years were randomized in to 2 equal groups (High Intensity & low intensity group . The High [80% HR max] & Low intensity [50 % HR max] groups underwent aerobic exercise training using Bicycle ergo meter (COSCO at 900kpm & 540kpm, for 15mins/day & 30mins/day respectively, 5days a week, for a period of 14weeks. Physical fitness index of each subject was recorded by Modified Harvard step test before & after intervention. RESULTS : After 14 weeks of aerobic training both the exercise groups had improvement in PFI, but high intensity gr oup had a significant (p<0.05 improvement in PFI (97.18 - 101.14 than low intensity group (98.12 - 100.6. CONCLUSION : High intensity aerobic exercise is effective in improving physical fitness.

Available prospective studies of obesity and asthma have used only body mass index (BMI) as an indicator for adiposity; studies using detailed obesity measures are lacking, and the role of physical fitness level and sedentary time remains unexplored in the link between obesity and asthma. To compare various anthropometric measures of obesity in relation to childhood asthma, and to further characterize the interrelations among central obesity, physical fitness level, sedentary time, and asthma. The nationwide Taiwan Children Health Study followed 2,758 schoolchildren from fourth to sixth grade, annually collecting data regarding physical fitness, sedentary time, obesity measures (comprising body weight and height, abdominal and hip circumference, skin fold thickness, and body composition), asthma, and pulmonary function tests. The generalized estimating equation was used for 3 years of repeated measurements to analyze the interrelation among obesity, sedentary time, physical fitness level, and asthma; a structural equation model was used to explore the pathogenesis among these factors. Asthma incidence was analyzed during a 2-year follow-up among centrally obese and nonobese groups in baseline children without asthma. Central obesity most accurately predicts asthma. Low physical fitness levels and high screen time increase the risk of central obesity, which leads to asthma development. Obesity-related reduction in pulmonary function is a possible mechanism in the pathway from central obesity to asthma. Central obesity measures should be incorporated in childhood asthma risk predictions. Children are encouraged to increase their physical fitness levels and reduce their sedentary time to prevent central obesity-related asthma.

The aim of this study is to evaluate the association between physical activity level and physical fitness with erectile dysfunction in men aged 40-75 years. We examined 180 men aged 40-75 years. The individuals were evaluated for age, presence of dyslipidemia and smoking and for anthropometric parameters for the characterization of body mass index. For assessing the level of physical fitness, a test was performed to measure the indirect maximum oxygen consumption. The evaluation of erectile function was made by the International Index of Erectile Function questionnaire and assessment of physical activity level by the International Physical Activity questionnaire in its short version. This study showed that younger men with higher physical activity and better physical fitness are less likely to suffer from erectile dysfunction. Multivariable analysis through logistic regression showed that age (odds ratio (OD)=1.15; 95% confidence interval (95% CI)=1.07-1.23), physical activity (OD=10.38; 95% CI=3.94-27.39) and physical fitness (OD=4.62; 95% CI=1.75-12.25) were independent variables associated with erectile dysfunction. This study reinforces the concept that healthy habits have a direct effect on erectile function.

The main aim of the present study (FITFATTWIN) was to investigate how physical activity level is associated with body composition, glucose homeostasis, and brain morphology in young adult male monozygotic twin pairs discordant for physical activity. From a population-based twin cohort, we systematically selected 10 young adult male monozygotic twin pairs (age range, 32-36 yr) discordant for leisure time physical activity during the past 3 yr. On the basis of interviews, we calculated a mean sum index for leisure time and commuting activity during the past 3 yr (3-yr LTMET index expressed as MET-hours per day). We conducted extensive measurements on body composition (including fat percentage measured by dual-energy x-ray absorptiometry), glucose homeostasis including homeostatic model assessment index and insulin sensitivity index (Matsuda index, calculated from glucose and insulin values from an oral glucose tolerance test), and whole brain magnetic resonance imaging for regional volumetric analyses. According to pairwise analysis, the active twins had lower body fat percentage (P = 0.029) and homeostatic model assessment index (P = 0.031) and higher Matsuda index (P = 0.021) compared with their inactive co-twins. Striatal and prefrontal cortex (subgyral and inferior frontal gyrus) brain gray matter volumes were larger in the nondominant hemisphere in active twins compared with those in inactive co-twins, with a statistical threshold of P physical activity is associated with improved glucose homeostasis and modulation of striatum and prefrontal cortex gray matter volume, independent of genetic background. The findings may contribute to later reduced risk of type 2 diabetes and mobility limitations.

The field of complex fluids is a rapidly developing, highly interdisciplinary field that brings together people from a plethora of backgrounds such as mechanical engineering, chemical engineering, materials science, applied mathematics, physics, chemistry and biology. In this melting pot of science, the traditional boundaries of various scientific disciplines have been set aside. It is this very property of the field that has guaranteed its richness and prosperity since the final decade of the 20th century and into the 21st. The C3 Commission of the International Union of Pure and Applied Physics (IUPAP), which is the commission for statistical physics that organizes the international STATPHYS conferences, encourages various, more focused, satellite meetings to complement the main event. For the STATPHYS22 conference in Bangalore (July 2004), Iran was recognized by the STATPHYS22 organizers as suitable to host such a satellite meeting and the Institute for Advanced Studies in Basic Sciences (IASBS) was chosen to be the site of this meeting. It was decided to organize a meeting in the field of complex fluids, which is a fairly developed field in Iran. This international meeting, and an accompanying summer school, were intended to boost international connections for both the research groups working in Iran, and several other groups working in the Middle East, South Asia and North Africa. The meeting, entitled `Statistical Physics of Complex Fluids' was held at the Institute for Advanced Studies in Basic Sciences (IASBS) in Zanjan, Iran, from 27 June to 1 July 2004. The main topics discussed at the meeting included: biological statistical physics, wetting and microfluidics, transport in complex media, soft and granular matter, and rheology of complex fluids. At this meeting, 22 invited lectures by eminent scientists were attended by 107 participants from different countries. The poster session consisted of 45 presentations which, in addition to the main topics of the

Individual fitness, an important component of combat readiness, has been found to be deficient in some Reserve Component units of the United States Army. We evaluated a program of monthly physical training in an environment of increasing emphasis on unit physical fitness in an effort to determine the effect on unit performance on the semi-annual Army Physical Fitness Test (APFT). This program was examined in a retrospective manner to establish its effectiveness over a 6-month period. No statistically significant improvement in APFT scores could be found over the course of the study, suggesting that such a program is not an efficient means of improving unit fitness in the Reserve Components of the United States Army.

Background The relation among physical activity (PA), fitness, cognitive function, and academic achievement in children is receiving considerable attention. The utility of PA to improve cognition and academic achievement is promising but uncertain; thus, this position stand will provide clarity from the available science. Objective To answer the following questions: (1) among children aged 5-13, do PA and physical fitness influence cognition, learning, brain structure, and brain function? (2) among children aged 5-13, do PA, physical education, and sports programs influence standardized achievement test performance and concentration/attention? Study Eligibility Criteria Primary source articles published in English in peer-reviewed journals. Articles that presented data on, PA, fitness or physical education (PE)/sport participation and cognition, learning, brain function/structure, academic achievement, or concentration/attention were included. Data Sources Two separate searches were performed to identify studies that focused on (1) cognition, learning, brain structure, and brain function; and (2) standardized achievement test performance and concentration/attention. PubMed, ERIC, PsychInfo, SportDiscus, Scopus, Web of Science, Academic Search Premier, and Embase were searched (January 1990- September 2014) for studies that met inclusion criteria. Sixty-four met inclusion criteria for the first search (cognition/learning/brain) and 73 studies met inclusion criteria for the second search (academic achievement/concentration). Study appraisal and synthesis methods Articles were grouped by study design as cross-sectional, longitudinal, acute, or intervention trials. Considerable heterogeneity existed for several important study parameters, therefore results were synthesized and presented by study design. Results A majority of the research supports the view that physical fitness, single bouts of PA, and PA interventions benefit children's cognitive functioning. Limited

The effect of exercise modalities on determinants of sarcopenia, specifically, lean tissue mass, maximal voluntary isometric contraction (MVIC), muscle quality (MQ), and cardiorespiratory fitness (VO(2)peak) over 12 weeks were studied in 42 (45-55 years, 60 days of amenorrhea, with hypertrophy, 2-4 s tension, ST(ht) = 8), endurance training (intermittent, >/=48 h rest, ET(i) = 7; consecutive, 24 h, ET(c) = 9) and autogenic training group (AT = 11). ST and ET met 60 min day(-1), 3 days week(-1) and AT 1 day week(-1). Leg extension, incremental cycling with gas exchange, dual-energy X-ray absorptiometry, and blood analysis were tested. The MANOVA revealed that ST(ss) improved MVIC (P < 0.01) and MQ (P = 0.01). The VO(2)peak also increased significantly in ET group by 28% (ET(i): P = 0.02, ET(c): P = 0.01). A modality-specific effect on strength, MQ, and VO(2)peak in perimenopausal females was duly noted.

Promoting physical fitness of young-older adults is essential in reducing healthcare expenditures which would occur in the future for those with chronic health problems. The silver yoga exercise programme was developed to accommodate the reduced body flexibility experienced by many older adults and was critically reviewed by experts and pilot-tested with community-dwelling older adults. This study aimed to test older adults' physical fitness after a 24-week silver yoga exercise programme and to examine whether the programme could be further shortened to fit senior activity centres' programme designs. A quasi-experimental, pre-post tests design was used: baseline, at 12-week and at 24-week periods. Convenience samples of 204 subjects were recruited from eight senior activity centres and 176 subjects completed the study. Subjects were randomly assigned into three groups based on the centres: (1) Experiment I: complete silver yoga with stretching and meditation, (2) Experiment II: shortened silver yoga without the guided-imagery meditation and (3) Wait-list control. The interventions were conducted three times per week for 24 weeks. Physical fitness indicators included body compositions, cardiovascular-respiratory functions, physical functions and the range of motion. At the end of the 24-week period, the physical fitness of subjects in Experiments I and II had significantly improved whether or not guided-imagery meditation was used and all had better physical fitness than subjects in the control group (all p fitness of older adults in both the 70-minute complete silver yoga group and the 55-minute shortened silver yoga group had significantly improved after the interventions. It was recommended that the silver yoga programme be shortened by eliminating the guided-imagery meditation. The shortened silver yoga exercise programme is recommended to be incorporated as an activity programme in community-settings to promote the physical fitness of older adults.

The current study examines the relationships between physical activity and fitness and reactivity to a musical performance stressor (MPS). Numerous studies suggest that being fitter and more physically active has a beneficial effect on individuals' cardiovascular responses to laboratory-based mental challenges. The results are equivocal regarding the transfer of such benefits to real world contexts such as musical performance. Forty six advanced music students completed this assessment. All participants completed a 20-min pre-performance assessment of heart rate (HR), HR variability (HRV) and blood pressure. Participants also completed baseline measures and a sub-maximal fitness assessment on a separate day. A positive association between fitness and HR pre-MPS was found. Fitness was also positively associated with root mean square SD RR(interval) before the MPS. Higher fitness was related to lower state anxiety post-MPS. Implications of the findings are discussed in relation to classical musicians' day-to-day work and performance.

This final summary report covers the five experiments that were conducted over a 24-month period beginning May 1, 1967 and ending April 30, 1969. Experiment I revealed that running and riding a bicycle ergometer produced similar gains in physical fitness variables. In Experiment I the subjects exercising at a 180 heart rate made a greater improvement in physical fitness than did those exercising a t a 140 or 160 heart rate. In Experiment II the subjects who exercised sixty minutes per day made greater gains on specified components of physical fitness than did those who exercised twenty or forty minutes per day, twelve times per week made greater gains on specified components of physical fitness than did those who exercised three or six times per week. In Experiment V, it was found that subjects could maintain a moderate level of fitness by exercising at a pulse rate of 160 beats per minute for twenty-minute periods three times per week, that subjects who "overtrained" by exercising twice daily to near exhaustion increased in fitness and that those subjects who discontinued training decreased in fitness.

An accurate physical fitness survey could be useful in research and clinical care. To estimate the validity and reliability of a Self-Reported Fitness (SRFit) survey; an instrument that estimates muscular fitness, flexibility, cardiovascular endurance, BMI, and body composition (BC) in adults ≥ 40 years of age. 201 participants completed the SF-36 Physical Function Subscale, International Physical Activity Questionnaire (IPAQ), Older Adults' Desire for Physical Competence Scale (Rejeski), the SRFit survey, and the Rikli and Jones Senior Fitness Test. BC, height and weight were measured. SRFit survey items described BC, BMI, and Senior Fitness Test movements. Correlations between the Senior Fitness Test and the SRFit survey assessed concurrent validity. Cronbach's Alpha measured internal consistency within each SRFit domain. SRFit domain scores were compared with SF-36, IPAQ, and Rejeski survey scores to assess construct validity. Intraclass correlations evaluated test-retest reliability. Correlations between SRFit and the Senior Fitness Test domains ranged from 0.35 to 0.79. Cronbach's Alpha scores were .75 to .85. Correlations between SRFit and other survey scores were -0.23 to 0.72 and in the expected direction. Intraclass correlation coefficients were 0.79 to 0.93. All P-values were 0.001. Initial evaluation supports the SRFit survey's validity and reliability.

Fitness has become more popular due to the cultural phenomenon that being fit can enhance one’s perception of beauty. The sprouting of various outlets for physical activity such as bodybuilding gyms that cater to weightlifting, outdoor group dance classes, sports camps and cause-oriented marathons can be noticed in numerous parts of the world. But slowly its concept, that being fit is a mere physical representation of beauty, is shifting into a more health-oriented consciousness. Annual reports have shown that coronary heart disease is still in the top rank of the death causes in the world. This information has led more people to protect their health through several lifestyle improvements, with regular exercise being one of these methods to achieve health goals. Its numerous benefits range from the lowering of blood pressure, heightened learning capacity to the improvement of mood. The health-rooted awareness of the need for physical activities to support one’s daily requirement has spread worldwide and has now been recognized by a lot of people. Parks are usually designed with amenities such as playgrounds, pathways and wide open spaces where people from all walks of life convene, interact with each other and do various physical activities. With this in mind, the capacity of parks to host such activities has to be studied to determine which components do people who engage in active healthy lifestyles find highly attractive and usable. An analysis of such could lead to effective space programming of our local neighborhood parks making it more perceptive to the physical needs of the people. Two major sports complexes from South East Asia have been used as case studies to assess the responsiveness of the locals to the amenities offered in each complex to address health goals. The comparison revealed that the Gelora Bung Karno Complex in Jakarta, Indonesia has more activity-oriented amenities and longer operating hours, making it more receptive to meet the

Full Text Available BACKGROUND: Cardiorespiratory fitness (CRF is a major factor influencing health and disease outcomes including all-cause mortality and cardiovascular disease. Importantly CRF is also modifiable and could therefore have a major public health impact. Early life exposures play a major role in chronic disease development. Our aim was to explore the potential prenatal and childhood origins of CRF in later life. METHODS/PRINCIPAL FINDINGS: This sub-study of the HBCS (Helsinki Birth Cohort Study includes 606 men and women who underwent a thorough clinical examination and participated in the UKK 2-km walk test, which has been validated against a maximal exercise stress test as a measure of CRF in population studies. Data on body size at birth and growth during infancy and childhood were obtained from hospital, child welfare and school health records. Body size at birth was not associated with adult CRF. A 1 cm increase in height at 2 and 7 years was associated with 0.21 ml/kg/min (95% CI 0.02 to 0.40 and 0.16 ml/kg/min (95% CI 0.03 to 0.28 higher VO2max, respectively. Adjustment for adult lean body mass strengthened these findings. Weight at 2 and 7 years and height at 11 years became positively associated with CRF after adult lean body mass adjustment. However, a 1 kg/m(2 higher BMI at 11 years was associated with -0.57 ml/kg/min (95% CI -0.91 to -0.24 lower adult VO2max, and remained so after adjustment for adult lean body mass. CONCLUSION/SIGNIFICANCE: We did not observe any significant associations between body size at birth and CRF in later life. However, childhood growth was associated with CRF in adulthood. These findings suggest, importantly from a public point of view, that early growth may play a role in predicting adult CRF.

Full Text Available Many health benefi ts are associated with physical activity level (PAL, but no standardized approaches to measurement exist, and comparisons and surveillance are problematic. The aim of this study was to verify the level ofagreement between the results of the International Physical Activity Questionnaire (IPAQ: short and the Habitual Physical Activity Questionnaire (HPAQ with true cardiorespiratory fi tness (VO2max, in order to classify young men and women ashaving PAL that is either adequate or inadequate for good health. A convenience sample was studied, composed of 105 young adults (43 male physical education students; 28 female physical education students; 34 males not studying physicaleducation. Both questionnaires were self-administered under the identical conditions. Values for VO2max were obtained using Cooper’s 12 min running test. Subjects were classifi ed as having PAL and VO2max that were adequate or inadequatefor good health. The cut off points used to defi ne adequate VO2max ≥44 ml/kg/min-1 for men and ≥33 ml/kg/min-1 for women. Agreement was assessed using a 2x2 contingency table. Percentage agreement ranged from 51.10% to 64.70% for theHPAQ and was 47.06% for the IPAQ. Agreement was higher for the HPAQ than for the IPAQ. Women overestimated their PAL by HPAQ and men underestimated their PAL by both questionnaires. The fi ndings of this study suggest that the HPAQ tends to be more accurate than the IPAQ.

Full Text Available Background & aim: Background & aim: Physical fitness is essential for maintaining optimal health and can be achieved and improved by doing physical activities. Maximal oxygen consumption (VO2 max has been used as a measure of physical fitness. This study aimed to determine the effect of jogging program on midwives' physical fitness. Methods:In this randomized controlled trial two large healthcare centers in Mashhad were randomly selected and each center assigned to either intervention or control group. 60 employed midwives, working at these centers, were selected via convenience sampling. The intervention group performed aerobic exercises at 30-60% VO2 max during 24 sessions. At the beginning and end of the study, participants’ physical fitness was measured by calculating VO2 max, using Bruce test. Independent t-test, paired t-test, Mann-Whitney U, Wilcoxon, and Chi-square tests were carried out using SPSS version 19 to analyse data. Results: The two groups showed no significant difference in terms of age, marital status, level of education, economic status and body mass index (P>0.05. Mean VO2 max in the intervention group (30.6±9.1 was significantly higher than that of the control group (24.3±7.3 (P=0.023. Participants' physical fitness was increased up to 30% by jogging. Conclusion:As the results indicated, jogging could improve midwives’ physical fitness. Therefore, it is essential that health system directors pay more attention to providing facilities at every workplace in order to improve employees’ physical fitness.

"Obesity" is considered a feature of youth with DS but whether "low physical fitness" is also a feature is unknown. The aim of this case-control study was to compare the levels of fatness and fitness in adolescents with and without DS. Participants included 17 (5 girls) adolescents with DS aged 12-18 years and a control group of 94 (45 girls) adolescents without DS aged 12-16 years. The ALPHA health-related fitness test battery for children and adolescents was selected to assess fatness and fitness in both groups. There were no differences in levels of fatness between groups (all P > 0.27). Adolescents with DS had lower levels of fitness in all the tests than adolescents without DS (all P fitness than their peers without DS. Copyright © AULA MEDICA EDICIONES 2013.

Physical activity and exercise training (ET) enhance overall cardiorespiratory fitness (ie, fitness), thus producing many benefits in the primary and secondary prevention of cardiovascular diseases. Substantial evidence also indicates that acute and chronic inflammation is involved in the development and progression of atherosclerosis and major cardiovascular events. The most commonly utilized marker of inflammation is C-reactive protein (CRP). In this review, we discuss the importance of inflammation, especially CRP, as a cardiovascular risk marker by reviewing an abundant cross-sectional and clinical intervention literature providing evidence that physical activity, enhanced fitness, and ET are inversely associated with CRP and that being overweight or obese is directly related with inflammation/CRP. Although we discuss the controversy regarding whether or not ET reduces CRP independent of weight loss, clearly physical activity, improved fitness, and ET are associated with reductions in inflammation and overall cardiovascular risk in both primary and secondary prevention.
Full Text Available Objective. To investigate the association of weight status with physical fitness among Chinese children. Methods. A total of 6929 children aged 6–12 years were selected from 15 primary schools of 5 provincial capital cities in eastern China. The height and fasting body weight were measured. The age-, sex-specific BMI WHO criteria was used to define underweight, overweight and obesity. Physical fitness parameters including standing broad jump, 50 m sprint, and 50 m∗8 shuttle run were tested. Results. The prevalence of underweight, overweight, and obesity was 3.1%, 14.9%, and 7.8%, respectively. Boys performed better than girls, and the older children performed better than their younger counterparts for all physical fitness tests. No significant difference in all three physical fitness tests were found between children with underweight and with normal weight, and they both performed better than their counterparts with overweight and obese in all three physical fitness tests. The likelihood of achieving good performance was much lower among overweight and obese children in comparison with their counterparts with normal weight (OR=0.13–0.54. Conclusions. An inverse association of obesity with cardiorespiratory fitness, muscle explosive strength, and speed was identified among Chinese children.

Full Text Available It is difficult to obtain detailed information on the context of physical activity at large geographic scales, such as the entire United States, as well as over long periods of time, such as over years. MapMyFitness is a suite of interactive tools for individuals to track their workouts online or using GPS in their phones or other wireless trackers. This method article discusses the use of physical activity data tracked using MapMyFitness to examine patterns over space and time. An overview of MapMyFitness, including data tracked, user information, and geographic scope, is explored. We illustrate the utility of MapMyFitness data using tracked physical activity by users in Winston-Salem, NC between 2006 and 2013. Types of physical activities tracked are described, as well as the percent of activities occurring in parks. Strengths of MapMyFitness data include objective data collection, low participant burden, extensive geographic scale, and longitudinal series. Limitations include generalizability, behavioral change as the result of technology use, and potential ethical considerations. MapMyFitness is a powerful tool to investigate patterns of physical activity across large geographic and temporal scales.

Full Text Available Mechanization and automation, swift communication and transport, computer usage and television viewing have reduced the need for vigorous occupations and discouraged involvement in leisure-time recreational activity. Studies have reported that there is a causal relationship between the risk of chronic disease incidence and mortality and physical activity and/or physical fi tness. Therefore, the aim of this review is to summarize and synthesize the association between health-related physical fi tness (aerobic endurance, fl exibility, strength/ endurance, body fat and chronic diseases. The papers reviewed demonstrate that higher and moderate levels of aerobic endurance, fl exibility, muscular strength/endurance, and desirable body fat levels, are very important for promoting health at all ages, and to avoid early development of chronic diseases. RESUMO A mecanização e a automação, o transporte e a comunicação rápidos, o uso do computador e da televisão têm diminuído atividades vigorosas, inclusive no tempo livre. Estudos reportam que a relação entre o risco de incidência de doenças crônico-degenerativas e a atividade física e/ou a aptidão física é causal. Portanto, o objetivo desta revisão é resumir e sintetizar a associação entre aptidão física relacionada à saúde (aptidão cardiorrespiratória, fl exibilidade, força/resistência muscular e gordura corporal e as doenças crônicodegenerativas. Os estudos mostram que altos e moderados níveis de aptidão cardiorrespiratória, fl exibilidade, força/resistência muscular, e um nível adequado de gordura são muito importantes para promover a saúde em todas idades, bem como evitar o desenvolvimento precoce de doenças crônico-degenerativas.

The relationship among physical activity (PA), fitness, cognitive function, and academic achievement in children is receiving considerable attention. The utility of PA to improve cognition and academic achievement is promising but uncertain; thus, this position stand will provide clarity from the available science. The purpose of this study was to answer the following questions: 1) among children age 5-13 yr, do PA and physical fitness influence cognition, learning, brain structure, and brain function? 2) Among children age 5-13 yr, do PA, physical education (PE), and sports programs influence standardized achievement test performance and concentration/attention? This study used primary source articles published in English in peer-reviewed journals. Articles that presented data on, PA, fitness, or PE/sport participation and cognition, learning, brain function/structure, academic achievement, or concentration/attention were included. Two separate searches were performed to identify studies that focused on 1) cognition, learning, brain structure, and brain function and 2) standardized achievement test performance and concentration/attention. PubMed, ERIC, PsychInfo, SportDiscus, Scopus, Web of Science, Academic Search Premier, and Embase were searched (January 1990-September 2014) for studies that met inclusion criteria. Sixty-four studies met inclusion criteria for the first search (cognition/learning/brain), and 73 studies met inclusion criteria for the second search (academic achievement/concentration). Articles were grouped by study design as cross-sectional, longitudinal, acute, or intervention trials. Considerable heterogeneity existed for several important study parameters; therefore, results were synthesized and presented by study design. A majority of the research supports the view that physical fitness, single bouts of PA, and PA interventions benefit children's cognitive functioning. Limited evidence was available concerning the effects of PA on learning

In this chapter, we review literature that examines the association among physical activity, aerobic fitness, cognition, and the brain in elementary school children (ages 7-10 years). Specifically, physical activity and higher levels of aerobic fitness in children have been found to benefit brain structure, brain function, cognition, and school achievement. For example, higher fit children have larger brain volumes in the basal ganglia and hippocampus, which relate to superior performance on tasks of cognitive control and memory, respectively, when compared to their lower fit peers. Higher fit children also show superior brain function during tasks of cognitive control, better scores on tests of academic achievement, and higher performance on a real-world street crossing task, compared to lower fit and less active children. The cross-sectional findings are strengthened by a few randomized, controlled trials, which demonstrate that children randomly assigned to a physical activity intervention group show greater brain and cognitive benefits compared to a control group. Because these findings suggest that the developing brain is plastic and sensitive to lifestyle factors, we also discuss typical structural and functional brain maturation in children to provide context in which to interpret the effects of physical activity and aerobic fitness on the developing brain. This research is important because children are becoming increasingly sedentary, physically inactive, and unfit. An important goal of this review is to emphasize the importance of physical activity and aerobic fitness for the cognitive and brain health of today's youth. © 2014 The Society for Research in Child Development, Inc.

To examine the reliability of a set of health-related physical fitness tests used in the European Union-funded Healthy Lifestyle in Europe by Nutrition in Adolescence (HELENA) Study on lifestyle and nutrition among adolescents. A set of physical fitness tests was performed twice in a study sample, 2 weeks apart, by the same researchers. A total of 123 adolescents (69 males and 54 females, aged 13.6+/-0.8 years) from 10 European cities participated in the study. Flexibility, muscular fitness, speed/agility and aerobic capacity were tested using the back-saver sit and reach, handgrip, standing broad jump, Bosco jumps (squat jump, counter movement jump and Abalakov jump), bent arm hang, 4 x 10 m shuttle run, and 20-m shuttle run tests. The ANOVA analysis showed that neither systematic bias nor sex differences were found for any of the studied tests, except for the back-saver sit and reach test, in which a borderline significant sex difference was observed (P=0.044). The Bland-Altman plots graphically showed the reliability patterns, in terms of systematic errors (bias) and random error (95% limits of agreement), of the physical fitness tests studied. The observed systematic error for all the fitness assessment tests was nearly 0. Neither a learning nor a fatigue effect was found for any of the physical fitness tests when repeated. The results also suggest that reliability did not differ between male and female adolescents. Collectively, it can be stated that the reliability of the set of physical fitness tests examined in this study is acceptable. The data provided contribute to a better understanding of physical fitness assessment in young people.

This report examines associations between injuries and flexibility, stretching, warm-up, and body composition. Military studies show that either too much or too little flexibility increases injury risk. Static stretching prior to exercise does not appear to reduce the overall injury incidence, although further research is needed on some types of injuries. Static stretching also appears to reduce strength and power (explosive strength). Warm-up (low intensity activity prior to exercise or sports) appears to reduce injury risk. Body mass index (BMI; weight in kg/ height in m²) is a surrogate measure of body fat because it is highly related to laboratory measures of body fat. However, Soldiers can also have a high BMI because of higher muscle mass. If high BMI reflects a larger percentage of body fat relative to height, injury risk might be increased because the additional fat would increase the intensity of physical activity, leading to more rapid fatigue and repetitive stress on the musculoskeletal system. Low BMI could reflect a paucity of fat or muscle/ bone, or both. Low BMI may make Soldiers more susceptible to injury if they lack the muscle mass or strength in the supportive structures (ligaments, bones) required to perform certain physical tasks, and if they overexert or overuse the available muscle mass or supportive structures. Studies in basic combat training show that both high and low BMI increases injury risk. However, studies among active duty Soldiers only show that injury risk increases as BMI increases, possibly because very few active duty Soldiers have very low BMI (i.e., less than 18 kg/m²). 2015.

The purpose of this study was to gain an insight into the physical and physiological profile of elite Belgian soccer players with specific regard to the player's position on the field. The sample consisted of 289 adult players from 6 different first division teams. The players were divided into 5 subgroups (goalkeepers, center backs, full backs, midfielders, and strikers) according to their self-reported best position on the field. The subjects performed anaerobic (10-m sprint, 5 × 10-m shuttle run [SR], squat jump [SJ], and countermovement jump [CMJ]) and aerobic (incremental running protocol) laboratory tests. The strikers had significantly shorter sprinting times (5-, 5- to 10-m time, and SR) compared with the midfielders, center backs, and goalkeepers, whereas the full backs were also significantly faster compared with the goalkeepers and the center backs. The goalkeepers and the center backs displayed higher jumping heights (total mean SJ = 40.7 ± 4.6 cm and CMJ = 43.1 ± 4.9 cm) compared with the other 3 positions, whereas the strikers also jumped higher than the full backs and the midfielders did. Regarding the aerobic performance, both full backs and the midfielders (61.2 ± 2.7 and 60.4 ± 2.8 ml · min(-1) · kg(-1), respectively) had a higher VO2max compared with the strikers, center backs, and goalkeepers (56.8 ± 3.1, 55.6 ± 3.5, and 52.1 ± 5.0 ml · min(-1) · kg(-1), respectively). From this study, it could be concluded that players in different positions have different physiological characteristics. The results of this study might provide useful insights for individualized conditional training programs for soccer players. Aside from the predominant technical and tactical skills, a physical profile that is well adjusted to the position on the field might enhance game performance.

Whereas nutrition has a crucial role on sport performance, it is not clear to what extent nutrition knowledge is associated with physical fitness. The aim of this study was to examine the current level of nutrition knowledge of soccer players and whether this level is associated with physical fitness. Soccer players (n = 185, aged 21.3 ± 4.9 yr, weight 72.3 ± 8.4 kg, and height 177.5 ± 6.4 cm) performed a battery of physical fitness tests (sit-and-reach test, SAR; physical working capacity in heart rate 170, PWC170; and Wingate anaerobic test, WAnT) and completed an 11-item nutrition knowledge questionnaire (NKQ). Low to moderate Pearson correlations (0.15 Soccer players with high score in NKQ were older (4.4 yr (2.2; 6.6), mean difference (95% confidence intervals)) and heavier (4.5 kg (0.6; 8.3)) with higher FFM (4.0 kg (1.1; 6.8)) and peak power (59 W (2; 116)) than their counterparts with low score. The moderate score in the NKQ suggests that soccer players should be targeted for nutrition education. Although the association between NKQ and physical fitness was low to moderate, there were indications that better nutrition knowledge might result in higher physical fitness and, consequently, soccer performance.

The objective of this work was to compare the anthropometric and physical fitness characteristics of Brazilian adolescents who practise team court sports and to compare specific parameters obtained for adolescents with data from the general population. This was a cross-sectional study of 1,348 male adolescents grouped as follows: basketball players (n = 287), indoor soccer players (n = 665), handball players (n = 108) and volleyball players (n = 288), all between 10 and 14 years of age. Anthropometric (body mass, body height, arm span, and body mass index) and physical fitness data (flexibility, muscular strength, explosive power, speed, aerobic fitness and agility) were collected. The Brazilian population was used as a reference and compared to the adolescent subjects using Z scores for all variables. Anthropometric characteristics and performances in physical fitness tests differed (p<0.05) among players of different sports. In addition, for each variable assessed, adolescents who practised team court sports showed similar or improved results compared to their counterparts in the general population (p<0.05). Furthermore, the anthropometric and physical fitness characteristics differed depending on the team court sport practised. These findings may elucidate which physical abilities are most impacted by the practise of a particular team sport as well as help teachers and physical education and sport professionals identify talented adolescents.

Physical inactivity is associated with poor physical fitness and increased body weight. This study examined the relationship between participation in organized sports and overweight as well as physical fitness in primary school children in southern Germany. Height, weight, and various components of physical fitness were measured in 995 children (7.6 ± 0.4 years). Sports participation and confounding variables such as migration background, parental education, parental body weight, and parental sports participation were assessed via parent questionnaire. Multiple logistic regression as well as multivariate analysis of covariance (MANCOVA) was used to determine associations between physical fitness, participation in organized sports, and body weight. Participation in organized sports less than once a week was prevalent in 29.2%, once or twice in 60.2%, and more often in 10.6% of the children. Overweight was found in 12.4% of the children. Children participating in organized sports more than once per week displayed higher physical fitness and were less likely to be overweight (OR = 0.52, P sports may be a crucial aspect in public health efforts addressing the growing problems associated with overweight and obesity.

Patients with fibromyalgia have diminished levels of physical fitness, which may lead to functional disability and exacerbating complaints. Multidisciplinary treatment comprising cognitive-behavioural therapy (CBT) and exercise training has been shown to be effective in improving physical fitness. However, due to the high drop-out rates and large variability in patients' functioning, it was proposed that a tailored treatment approach might yield more promising treatment outcomes. High-risk fibromyalgia patients were randomly assigned to a waiting list control group (WLC) or a treatment condition (TC), with the treatment consisting of 16 twice-weekly sessions of CBT and exercise training tailored to the patient's cognitive-behavioural pattern. Physical fitness was assessed with two physical tests before and 3 months after treatment and at corresponding intervals in the WLC. Treatment effects were evaluated using linear mixed models. The level of physical fitness had improved significantly in the TC compared with the WLC. Attrition rates were low, effect sizes large and reliable change indices indicated a clinically relevant improvement among the TC. A tailored multidisciplinary treatment approach for fibromyalgia consisting of CBT and exercise training is well tolerated, yields clinically relevant changes, and appears a promising approach to improve patients' physical fitness.

Medical school is stressful. Students commonly exhibit changes in dietary and physical activity patterns in response. We tracked measurements of physical fitness over 4 years in a cohort of students at the Uniformed Services University. Validated measures for specific components of physical fitness were measured in 170 students (94% of the Class of 2011) over the course of 4 years. Measurements included: (1) height and weight (body composition), (2) timed push-ups and sit-ups (muscular endurance), and (3) timed run (aerobic endurance). These measurements are part of annual physical readiness testing required for active duty service in the US military. Muscular endurance and aerobic capacity declined significantly over the 4 years of medical school. Changes in physical fitness were most pronounced during the preclinical years. There were inconsistent changes in body composition among students in the Army, Navy, and Air Force. Composite fitness scores declined significantly in Army and Navy students but not in the Air Force. Individual levels of physical fitness decline during medical school. Declines are most notable during the preclinical years. To promote student wellness, medical schools should incorporate student wellness activities as a routine part of the curriculum.
Full Text Available The purpose of this study was to investigate the association between physical fitness and mild cognitive impairment (MCI in elderly Koreans. This was a cross-sectional study that involved I34 men and 299 women aged 65 to 88 years. Six senior fitness tests were used as independent variables: 30 s chair stand for lower body strength, arm curl for upper body strength, chair-sit-and-reach for lower body flexibility, back scratch for upper body flexibility, 8-ft up-and-go for agility/dynamic balance, and 2-min walk for aerobic endurance. Global cognitive function was assessed using the Korean version of the Mini-Mental State Examination (MMSE. Potential covariates such as age, education levels, blood lipids, and insulin resistance (IR markers were also assessed. Compared to individuals without MMSE-based MCI, individuals with MMSE-based MCI had poor physical fitness based on the senior fitness test (SFT. There were significant positive trends observed for education level (p=0.00I and MMSE score (p<0.001 across incremental levels of physical fitness in this study population. Individuals with moderate (0R=0.34l, p=0.006 and high (0R=0.27l, p=0.007 physical ﬁtness based on a composite score of the SFT measures were less likely to have MMSE-based MCI than individuals with low physical ﬁtness (referent, 0R=I. The strength of the association between moderate (0R=O.377, p=0.038 or high (OR=O.282, p=0.050 physical fitness and MMSE-based MCI was somewhat attenuated but remained statistically significant even after adjustment for the measured compounding factors. We found that poor physical fitness was independently associated with MMSE-based MCI in elderly Koreans.
Full Text Available The main aim of the research was to find out whether there are any differences in physical fitness between non-overweight, overweight and obese female students. Research was carried out on 178 female students from the Faculty of Education Maribor (aged 20.3 years, SD = 1.09. The students were classified as non-overweight, overweight, and obese according to age and sex specific body mass index (BMI cut-off points. In order to assess their physical fitness, nine different tests that cover explosive leg power, repetitive trunk and upper extremities power, flexibility, balance, eye-hand coordination, agility, and endurance were used. ANOVA was used to assess the differences in physical fitness between nonoverweight, overweight, and obese groups. Statistical significance was set at the α level of 0.05. Results show that 79.9 % of students were in the non-overweight group, 14.0 % in the overweight group, and 6.61 % in the obese group. The differences in all physical fitness tests, except in sit-and-reach test and sit-ups test, between non-overweight, overweight, and obese female students are statistically significant (p < 0.05. We have established that the nonoverweight female students achieved a higher level of physical fitness than their overweight and obese peers. In addition, overweight students achieved a higher level of physical fitness than obese students. These data suggest, that in the early adulthood population the level of physical fitness and weight status are closely related.

Full Text Available Abstract Background The Self-determined Exercise and Learning For FITness (SELF-FIT is a multi-component school-based intervention based on tenets of self-determination theory. SELF-FIT aims to increase students’ moderate-to-vigorous physical activity (MVPA during physical education lessons, and enhance their autonomous motivation towards fitness activities. Using a cluster randomized controlled trial, we aim to examine the effects of the intervention on students’ MVPA during school physical education. Methods Secondary 2 students (approximately aged 14 years from 26 classes in 26 different schools will be recruited. After baseline assessments, students will be randomized into either the experimental group or wait-list control group using a matched-pair randomization. Teachers allocated to the experimental group will attend two half-day workshops and deliver the SELF-FIT intervention for 8 weeks. The main intervention components include training teachers to teach in more need supportive ways, and conducting fitness exercises using a fitness dice with interchangeable faces. Other motivational components, such as playing music during classes, are also included. The primary outcome of the trial is students’ MVPA during PE lessons. Secondary outcomes include students’ leisure-time MVPA, perceived need support from teachers, need satisfaction, autonomous motivation towards physical education, intention to engage in physical activity, psychological well-being, and health-related fitness (cardiorespiratory and muscular fitness. Quantitative data will be analyzed using multilevel modeling approaches. Focus group interviews will also be conducted to assess students’ perceptions of the intervention. Discussion The SELF-FIT intervention has been designed to improve students’ health and well-being by using high-intensity activities in classes delivered by teachers who have been trained to be autonomy needs supportive. If successful, scalable

Fatigue is a common and distressing symptom in cancer patients, especially in lymphoma patients. One hypothesized mechanism in the etiology of fatigue is a vicious circle between fatigue, physical inactivity, and deconditioning. However, the natural evolution of physical activity and physical fitness over the course of treatment is unknown. Therefore, the aim of this longitudinal study was to assess fatigue, physical activity, and physical fitness in lymphoma patients before, during, and after treatment. Fatigue was measured with the EORTC-QLQ-C30, physical activity with an accelerometer, and physical fitness with a maximal incremental cycle ergometer test, 6-min walking distance test, and muscle strength measurements. Differences between the three measurement moments and baseline differences between Hodgkin lymphoma and non-Hodgkin lymphoma, early and advanced disease, were analyzed. Twenty-nine patients were included. Functional exercise capacity and quadriceps force were impaired before the start of treatment (86 ± 15 and 82 ± 16 % of predicted value, respectively). Over the course of treatment, significant declines were found in hemoglobin, quadriceps force, handgrip force, and maximal oxygen uptake, while patients reported more fatigue (p values physical activity (r = 0.81), and physical functioning (r = -0.44). Large interindividual variations were found. The present study partially confirmed the hypothesized vicious circle between fatigue, physical inactivity, and deconditioning. Further research with larger samples and longer follow-up is needed to identify factors associated with individual variation in the evolution of fatigue, physical activity, and physical fitness.

Most of the studies on weight misperception have been carried out in the US where it has been estimated that 20-40% of overweight or obese people underestimate their weight status. The perception of the physical fitness is a little studied variable but suggested as relevant in the adoption of healthy behaviours. The aims were to analyze weight misperception and physical fitness perception in adolescents, evaluating the relationship between weight misperception and physical fitness perception and body weight management behaviours (diet and exercise) as well as to analyze the relationship between weight misperception and psychosocial well-being. A total of 655 students participated voluntarily in the study during which they completed a series of questionnaires. Weight and height of all participants were collected. Many young people misperceived their weight and its physical fitness. The majority of participants who were overweight or obese did not go on diet to manage their body weight. Those who overestimated their weight had the worst psycho-emotional state. The work is novel in Spain, it follows the methodology carried out in international studies on the same topic and the results are similar to those obtained in other populations. Weight misperception and physical fitness perception influence the adoption of healthy body weight management behaviors and is related to psychosocial well- being of young people.

Background: The predicted health benefits of becomingphysically active or fit will be exaggerated if health outcomes causefitness and activity rather than the converse in prospective andcross-sectional epidemiological studies. Objective: Assess whether therelationships of adiposity to fitness and activity are explained byadiposity prior to exercising. Design: Cross-sectional study of physicalfitness (running speed during 10km foot race) and physical activity(weekly running distance) to current BMI (BMIcurrent) and BMI at thestart of running (BMIstarting) in 44,370 male and 25,252 femaleparticipants of the National Runners' Health Study. Results: BMIstartingexplained all of the association between fitness and BMIcurrent in bothsexes, but less than a third of the association between physical activityand BMIcurrent in men. In women, BMIstarting accounted for 58 percent ofthe association between BMIcurrent and activity levels. The 95thpercentile of BMIcurrent showed substantially greater declines withfitness and activity levels than the 5th percentile of BMIcurrent in men(i.e., the negative slope for 95th percentile was 2.6-fold greater thanthe 5th percentile for fitness and 3-fold greater for activity) and women(6-fold and 3.4-fold greater, respectively). At all percentiles, theregression slopes relating BMIstarting to fitness were comparable orgreater (more negative) than the slopes relating BMIcurrent to fitness,whereas the converse was true for activity. Conclusion: Self-selectionbias accounts for all of the association between fitness and adiposityand probably a portion of other health outcomes, but has less affect onassociations involving physical activity

RESULTS: A strong dose-response relation between cardiorespiratory fitness and self-rated health as well as between physical activity level and self-rated health among both women and men was found. Within categories of physical activity, odds ratios for optimal self...
Full Text Available Abstract Background The prevalence of metabolic syndrome has increased over the last few decades in adolescents and has become an important health challenge worldwide. This study analyzed the relationships between metabolic risk factors (MRF and physical activity (PA and physical fitness (PF in a sample of Azorean adolescents. Methods A cross-sectional school-based study was conducted on 417 adolescents (243 girls aged 15-18 from the Azorean Islands, Portugal. Height, weight, waist circumference, fasting glucose, HDL-cholesterol, triglycerides, and blood pressure were measured. A sum of MRF was computed, and adolescents were classified into three groups: no MRF, one MRF and two or more MRF. PA was assessed by a sealed pedometer. PF was assessed using five tests from the Fitnessgram Test Battery. Dietary intake was obtained using a semi-quantitative food frequency questionnaire. Results Mean daily steps for girls and boys were 7427 ± 2725 and 7916 ± 3936, respectively. Fifty-nine percent of the adolescents showed at least one MRF and 57.6% were under the healthy zone in the 20 m Shuttle Run Test. Ordinal logistic regression analysis showed that after adjusting for sex, body mass index, socio-economic status and adherence to a Mediterranean diet, adolescents who were in the highest quartile of the pedometer step/counts (≥9423 steps/day and those who achieved the healthy zone in five tests were less likely to have one or more MRF (OR = 0.56;95%CI:0.33-0.95; OR = 0.55;95%CI:0.31-0.98, respectively. Conclusions Daily step counts and PF levels were negatively associated with having one or more MRF among Azorean adolescents. Our findings emphasize the importance of promoting and increasing regular PA and PF to reduce the public health burden of chronic diseases associated with a sedentary lifestyle.

The objective of this systematic review was to examine the relationship between outdoor time and: (1) physical activity, (2) cardiorespiratory fitness, (3) musculoskeletal fitness, (4) sedentary behaviour; or (5) motor skill development in children aged 3–12 years. We identified 28 relevant studies that were assessed for quality using the GRADE framework. The systematic review revealed overall positive effects of outdoor time on physical activity, sedentary behaviour, and cardiorespiratory fitness, although causality could not be assumed due to a lack of RCTs. Motor skill development was unrelated to outdoor time; however, this relationship was only examined in a single study of preschool children. No studies were found that examined associations between outdoor time and musculoskeletal fitness. PMID:26062039

In adults, there is a substantial body of evidence that physical inactivity or low cardiorespiratory fitness levels are strongly associated with the development of metabolic syndrome. Although this association has been studied extensively in adults, little is known regarding this association in adolescents. The aim of this study was to analyze the association between physical activity and cardiorespiratory fitness levels with metabolic syndrome in Brazilian adolescents. A random sample of 223 girls (mean age, 14.4 ± 1.6 years) and 233 boys (mean age, 14.6 ± 1.6 years) was selected for the study. The level of physical activity was determined by the Bouchard three-day physical activity record. Cardiorespiratory fitness was estimated by the Leger 20-meter shuttle run test. The metabolic syndrome components assessed included waist circumference, blood pressure, HDL-cholesterol, triglycerides, and fasting plasma glucose levels. Independent Student t-tests were used to assess gender differences. The associations between physical activity and cardiorespiratory fitness with the presence of metabolic syndrome were calculated using logistic regression models adjusted for age and gender. A high prevalence of metabolic syndrome was observed in inactive adolescents (males, 11.4%; females, 7.2%) and adolescents with low cardiorespiratory fitness levels (males, 13.9%; females, 8.6%). A significant relationship existed between metabolic syndrome and low cardiorespiratory fitness (OR, 3.0 [1.13-7.94]). The prevalence of metabolic syndrome is high among adolescents who are inactive and those with low cardiorespiratory fitness. Prevention strategies for metabolic syndrome should concentrate on enhancing fitness levels early in life.

Full Text Available OBJECTIVE: The purpose of this study was twofold: to analyze the association between physical fitness and academic attainment, and to determine the influence of screen time on the association between physical fitness and academic attainment.METHODS: A cross-sectional study including 395 schoolchildren from seven schools of the Maule Region, Chile (mean age 12.1 years; 50.4% boys participated in the autumn of 2014 (March to June. Self-reported physical activity and screen time were evaluated. The study measured academic achievement (mean of the grades obtained in several core subjects, physical fitness (cardiorespiratory fitness and muscular strength, weight, height, parental education, and socioeconomic status. Linear regression analysis was used to analyze the relationships between physical fitness and academic attainment after adjusting for potential confounders by gender. Analysis of variance was used to analyze the differences in academic attainment according to fitness and screen time categories (< 2 hours/day and ≥ 2 hours/day.RESULTS: In both genders good cardiorespiratory fitness levels were associated with high language (ß = 0.272-0.153 and mean academic attainment (ß = 0.192-0.156 grades; however, after adjusting for screen time and other potential confounders, these associations disappear. Similarly, no relationship was observed after analyzing those children who spend more hours of screen time (≥ 2 hours/day.CONCLUSIONS: Academic attainment is associated with higher cardiorespiratory fitness levels; however, it was weakly impaired by screen time. These findings seem to suggest that parents and policymakers should minimize the negative effects of screen time on children's lives to maximize the beneficial effect of healthy habits on academic attainment.

Mixed gender basic military training (BMT) is adopted to integrate the female South African soldier into the military. This study aimed to assess gender differences before, during (12 weeks), and after a 20-week mixed BMT course and determine if BMT significantly reduced these differences. A total of 186 soldiers (114 male: mean age = 21.0 ± 1.1 year; 72 female: mean age = 20.5 ± 1.2 year) completed the BMT course and all anthropometric, physical fitness, explosive power, and hand grip strength measurements. Repeated-measures analysis of variance was used to model BMT data with main effects for gender comparison between males and females, and time main effect for evaluation of differences between weeks 1, 12, and 20 of BMT, as well as an interaction effect for differences in changes over time for males and females. Alpha was set at α ≤0.05. Male soldiers were significantly taller (p fitness test. Differences in power output and hand grip strength remained unchanged. Large initial anthropometrical and physical fitness differences decreased but were still obvious at the end of BMT. BMT should bridge the physical gap between male and female soldiers to ensure they can all perform the same duties. The enforcing of equal minimum physical fitness requirements for acceptance into BMT; conditional acceptance into the military subject to the successful completion of a bridging course aimed at improving physical fitness in individuals who do not meet the minimum physical fitness requirements for acceptance; and developing a cyclic physical training program with different entry points, dependent on initial physical performance at the start of BMT, ensuring adequate progression and overload for all soldiers are possible avenues to explore to achieve this goal.

Full Text Available Background: Lower level of motor competences may result in unsuccessful engaging of children in physical activities as early as pre-school age and also prepubescent ages. This may subsequently lead to a spiral of forming negative attitudes towards an active lifestyle and may be accompanied by a negative trend in weight status and physical fitness outcomes. Objective: The aim of the study was to identify and analyze differences in physical fitness and somatic parameters of primary school-aged children according to level of their gross motor coordination. Methods: A sample of 436 children aged 7 to 10 years, of which were 222 girls and 214 boys, performed physical fitness tests - Eurofit test battery. The level of motor coordination was assessed using the test battery Körperkoordination-Test-für-Kinder (KTK. The anthropometric data (body mass, body height, sum of five skinfolds were measured. The one-way ANOVA was used to assess differences in physical fitness test items and anthropometry parameters between children with normal motor quotient (MQ ≥ 86 and decreased levels of gross motor coordination (MQ ≤ 85. Results: Research findings indicate a strongly negative trend in physical development of children with motor deficits (MQ ≤ 85. The results of ANOVA revealed significantly less favourable level of most of the assessed physical fitness parameters in children with decreased level of motor coordination. Conclusions: The findings suggest that physical fitness outcomes of primary school-aged children are associated with a lower level of motor coordination. Motor coordination probably plays an important role in preventing, or moderating the so-called negative trajectory leading to childhood overweight or obesity.

First, this study aimed to investigate if four extra physical education (PE) lessons per week improved children's development in physical fitness. Second, to investigate if the extra PE lessons improved development in physical fitness for children with lower levels of fitness at baseline. This study was a longitudinal controlled school-based study. The study population consisted of 10 Danish public schools with children in preschool to fourth grade (cohorts 0-4) with 2.5-year follow-up. Six schools had extra PE and four schools had normal PE. In total 1247 children were included (normal PE = 536, extra PE = 711). Development in fitness was analyzed using a composite z-score from six fitness tests. Multilevel mixed-effects linear regression was used to examine the association between school type and development in fitness. Extra PE increased the total development of composite z-score units among children enrolled in cohort 4 and borderline in cohort 3 with 1.06 (95% confidence interval 0.48-1.65) and 0.52 z-score units (-0.06 to 1.09), respectively. Children in the lower 50 percentiles increased their development with 0.47 (0.08-0.85) z-score units. Extra PE in schools improved development in fitness for cohort 4 and borderline for cohort 3 among all children. Extra PE improved fitness development across all cohorts among children with low fitness levels. © 2014 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

Full Text Available Poor physical fitness and low serum vitamin D are known to be modifiable risk factors for cognitive declines with normal aging. We investigated the association of physical fitness and serum vitamin D levels with global cognitive function in older adults. In this cross-sectional study, a total of 412 older Korean adults (108 men aged 74.4 ± 6.0 years and 304 women aged 73.1 ± 5.4 years completed the Korean version of Mini-Mental State Examination (MMSE to assess global cognitive performance and the senior fitness test to assess strength, flexibility, agility, and endurance domains of physical fitness. Body mass index, percent body fat, serum vitamin D, geriatric depression scale (GDS, level of education, smoking, and history of cardiovascular or cerebrovascular disease were also assessed as covariates. Age, sex, GDS, and body fatness were negatively associated with MMSE-based cognitive performance. Serum vitamin D and physical fitness were positively associated with MMSE-based cognitive performance. Multivariate linear regression showed that agility (partial R2 = -0.184, p = 0.029 and endurance (partial R2 = 0.191, p = 0.022 domains of physical fitness along with serum vitamin D (partial R2 = 0.210, p = 0.012 were significant predictors for global cognitive performance after controlling for covariates (i.e., age, sex, education, GDS, body fatness, and comorbidity index. The current findings of the study suggest that promotion of physical fitness and vitamin D supplementation should be key components of interventions to prevent cognitive decline with normal aging.

Motor fitness and physical activity are important aspects of a healthy development in childhood and adolescence. However, the assessment of motor fitness and physical activity is not subject to standardized criteria; furthermore, the samples investigated do not provide a representative image of the whole population. Therefore, the existing data only allow very limited statements on the state and development of motor fitness and physical activity. The "Motorik" module, as part of the German Health Interview and Examination Survey for Children and Adolescents (KiGGS), offers nationwide representative data on the motor fitness and physical activity of children and adolescents for the first time. Besides the baseline-analysis, another aim is to analyse the complex relationship between motor fitness, physical activity and health. Motor fitness, based on the systematisation of motor abilities, was assessed using a test profile. The test profile consists of 11 items measuring cardiorespiratory fitness, strength, coordination and mobility. Physical activity was assessed using a questionnaire containing 51 items on the duration, intensity and frequency of physical activity in everyday life, during leisure time, at school and in sports clubs. The above-mentioned questionnaire subtopics were supplemented by questions on the weekly prevalence of at least 60 minutes of daily physical activity, on material and local conditions, as well as on cognition and motivation for physical activity. In the years 2004 to 2006, the motor fitness and physical activity of 4,529 children and young people between the ages of 4 and 17 years was investigated on 168 sample points in the context of the "Motorik" module. Half of the children and adolescents investigated belong to the middle class, approximately 15% have a background of migration. The majority of the subjects come from small towns, about a quarter live in the city, less than 20% are settled in rural areas.

This study examined the association between physical fitness and academic achievement and determined the influence of socioeconomic status (SES) on the association between fitness and academic achievement in school-aged youth. Overall, 1,701 third-, sixth-, and ninth-grade students from 5 school districts participated in the assessments. Fitness was assessed using FITNESSGRAM (aerobic fitness, muscular strength, muscular endurance, flexibility, and body composition). Results were used to determine individual fitness scores. Academic achievement was measured by standardized tests for Math (all grades), English (all grades), and Social Studies (sixth and ninth grades only). The SES was determined using eligibility for free and reduced lunch program. There were no significant differences between fitness groups for Math and English in third-grade students. Sixth- and ninth-grade students with high fitness scored significantly better on Math and Social Studies tests compared with less fit students. Lower SES students scored significantly worse on all tests. Muscular strength and muscular endurance were significantly associated with academic achievement in all grades. Compared with all other variables, SES appears to have the strongest association with academic achievement. However, it also appears that high fitness levels are positively associated with academic achievement in school-aged youth. © 2013, American School Health Association.

Information about the regional distribution of health-related physical fitness status is necessary in order to tailor public health interventions, and due to a number of behavioral health risks caused by the increasing sedentary lifestyle. This study aimed to find differences between Croatian children's health-related physical fitness profiles in urban and rural areas. The sample for this study consisted of 2431 fifth-grade students (1248 boys and 1183 girls) from urban and rural areas of Croatia. The mean age of participants was 11.3 +/- 6.1 years. The differences between the health-related physical fitness of school children from urban and rural areas was computed using series of univariant analysis of variance and canonical discriminant analysis. The reliability of the tests was determined by Cronbach's alpha coefficients. Urban boys and girls significantly differ in body height from rural boys and girls. Body mass index and body fat percentage are slightly higher in the urban boys and girls but they do not differ significantly. Urban children perform significantly better in the 20 m dash, standing long jump and timed sit-ups. Urban and rural boys and girls do not differ significantly in the flexibility. This study determined if selected levels of urbanization affected the physical fitness status of children in Croatia. The results suggest that the differences in children's health-related physical fitness profiles are due to the level of urbanization.

Low physical fitness has been recognised as a prominent behavioural risk factor for cardiovascular diseases (CVD) and metabolic syndrome (MetS), and as an independent risk factor for all-cause mortality. No studies have systematically assessed physical fitness compared with a matched health control group in patients with schizophrenia. Eighty patients with schizophrenia and 40 age-, gender- and body mass index (BMI)-matched healthy volunteers were included. All participants performed an Eurofit test battery and filled out the International Physical Activity Questionnaire. Patients additionally had a fasting metabolic laboratory screening and were assessed for psychiatric symptoms. Patients with schizophrenia demonstrated significant differences from controls in whole body balance, explosive leg muscle strength, abdominal muscular endurance, and running speed. Inactive patients scored worse on most Eurofit items than patients walking for at least 30min per day. Low physical fitness was associated with illness duration, smoking, the presence of MetS and more severe negative, depressive and cognitive symptoms. Less physically active patients who smoke and suffer from high levels of negative, depressive and/or cognitive symptoms might benefit from specific rehabilitation interventions aimed at increasing physical fitness.

Because fitness level is a potent biomarker of health from an early age, the improvements of physical fitness performance through the promotion of physical activity could be important for the health of preschool children, particularly in obesity prevention. The purpose of this study is to determine the physical fitness in children aged 3-6 years, discriminating performance by sex, age and body mass index (BMI). A total of 3868 children from 3 to 6 years agreed voluntarily to participate. Demographic characteristics revealed that 1961 children were male (age: 55.71 ± 11.11 months old, BMI = 16.03 ± 1.93 kg/m2 ), and 1907 were female (age 56.16 ± 0.97 months old, BMI = 15.85 ± 1.89 kg/m2 ), and they were selected from 51 schools in southern Spain. Significant differences were found between sexes: boys showed a greater performance on cardio respiratory endurance, reaction time, strength and running speed. We found significant differences by sex in the different age groups (3, 4, 5 and 6 years old). Sex differences in physical fitness are evident at an early age; in addition, the relationship between physical fitness and BMI is inconsistent in preschool children. The improvements of physical fitness performance and its association with physical activity could be important for the health of children, particularly in obesity prevention. © 2016 John Wiley & Sons Ltd.

To examine the independent relation of physical activity (PA) and cardiorespiratory fitness (fitness) with measures of obesity in Mexican children. Children (N=193) in 5th and 6th grade from Guadalajara participated. Body mass index (BMI), sum of skinfolds (SS) and waist circumference (WC) were measured. PA was measured over four days using pedometry and fitness was measured using the 20 meter shuttle-run test. Fitness and PA were negatively related to the obesity measures in boys and girls (r=-0.57 to -0.64 and r=-0.18 to -0.23 respectively). Age adjusted significant differences in WC, BMI, and SS were observed between the lowest and highest fitness tertiles for boys and girls (pobesity than PA in this sample.

The purpose of this study was to assess anthropometry, physical fitness, and serum glucose and lipid levels in college students and to determine the relative impact of fitness level compared with body composition on blood chemistries related to metabolic syndrome. College students (n = 564; means +/- SD: age = 19.4 +/- 1.1 yr) participating in the Tufts University Longitudinal Health Study between 2000 and 2007 were examined for the relative impact of fitness level compared with body composition on serum glucose, triglycerides, HDL, LDL, and total cholesterol controlling for age and ethnicity. In this college population, 16.2% were overweight or obese, whereas 60% had body fat percentages above desirable levels. Higher percent body fat was associated with increased cholesterol and LDL in both men and women, and with increased triglyceride and decreased HDL in women (P < 0.05). Increased fitness was associated with increased HDL and decreased triglycerides in women and decreased serum glucose in men (P < 0.05). When dichotomized into "fit" and "unfit" groups, students who were fit demonstrated more optimal levels of serum glucose and lipids independent of percent body fat (P < 0.05). Several metabolic risk factors are already evident in a young college population, and both increased body fatness and decreased physical fitness were associated with metabolic risk. Being physically fit can confer an added benefit to a healthy body composition. It is therefore important to encourage both healthy weights and fitness in late adolescence as each play important and independent roles in biochemical parameters associated with increased chronic disease risk.

Abstract It was not known if, or to what degree, a relationship existed among academic achievement in science, physical fitness, and preadolescent obesity. This quantitative, correlational study explored the relationship between physical fitness, preadolescent obesity, and academic achievement in 136 seventh grade students at an urban middle school in South Carolina who received 50 minutes of physical education daily for one semester. The researcher hypothesized that the level of physical fitness influences preadolescent obesity and academic performance. The hypotheses stated that there would be a positive correlation between physical fitness and achievement in science, a negative correlation between preadolescent obesity and achievement in science, and a negative correlation between fitness and preadolescent obesity. Pearson product-moment correlations were used to test the hypotheses. Physical fitness was measured using the FitnessGram. Academic performance was measured using the science benchmark assessment. The results revealed that physical fitness was positively correlated with academic achievement (r = .32, p = .001), obesity was negatively related to academic achievement (r = -.27, p = .001), and students' BMI was negatively related to physical fitness (r = -.71, p school policy and public health in terms of the possibilities for physical activity interventions. Keywords: FitnessGram, physical fitness, preadolescent obesity, body mass index.
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.

The purpose of this study was twofold: to analyze the association between physical fitness and academic attainment, and to determine the influence of screen time on the association between physical fitness and academic attainment. A cross-sectional study including 395 schoolchildren from seven schools of the Maule Region, Chile (mean age 12.1 years; 50.4% boys) participated in the autumn of 2014 (March to June). Self-reported physical activity and screen time were evaluated. The study measured academic achievement (mean of the grades obtained in several core subjects), physical fitness (cardiorespiratory fitness and muscular strength), weight, height, parental education, and socioeconomic status. Linear regression analysis was used to analyze the relationships between physical fitness and academic attainment after adjusting for potential confounders by gender. Analysis of variance was used to analyze the differences in academic attainment according to fitness and screen time categories (levels were associated with high language (β=0.272-0.153) and mean academic attainment (β=0.192-0.156) grades; however, after adjusting for screen time and other potential confounders, these associations disappear. Similarly, no relationship was observed after analyzing those children who spend more hours of screen time (≥ 2 hours/day). Academic attainment is associated with higher cardiorespiratory fitness levels; however, it was weakly impaired by screen time. These findings seem to suggest that parents and policymakers should minimize the negative effects of screen time on children's lives to maximize the beneficial effect of healthy habits on academic attainment.

This study aimed to determine which of four selected physical fitness variables, would be most associated with blood pressure changes (systolic and diastolic) in a large sample of adolescents. This was a descriptive and cross-sectional, epidemiological study of 1,117 adolescents aged 14-19 years from southern Brazil. Systolic and diastolic blood pressure were measured by a digital pressure device, and the selected physical fitness variables were body composition (body mass index), flexibility (sit-and-reach test), muscle strength/resistance (manual dynamometer), and aerobic fitness (Modified Canadian Aerobic Fitness Test). Simple and multiple linear regression analyses revealed that aerobic fitness and muscle strength/resistance best explained variations in systolic blood pressure for boys (17.3% and 7.4% of variance) and girls (7.4% of variance). Aerobic fitness, body composition, and muscle strength/resistance are all important indicators of blood pressure control, but aerobic fitness was a stronger predictor of systolic blood pressure in boys and of diastolic blood pressure in both sexes.

Recent evidence makes a compelling case that US Army, Navy, and Air Force health-related physical fitness tests penalize larger, not just fatter, service members. As a result, they tend to receive lower scores than their lighter counterparts, the magnitude of which can be explained by biologic scaling laws. Larger personnel, on the other hand, tend to be better performers of work-related fitness tasks such as load carriage, heavy lifting, and materiel handling. This has been explained by empirical evidence that lean body mass and lean body mass to dead mass ratio (dead mass = fat mass and external load to be carried/lifted) are more potent determinants of performance of these military tasks than the fitness test events such as push-ups, sit-ups, or 2-mile-distance run time. Because promotions are based, in part, on fitness test performance, lighter personnel have an advancement advantage, although they tend to be poorer performers on many tests of work-related fitness. Several strategies have been proposed to rectify this incongruence including balanced tests, scaled scores, and correction factors--yet most need large-scale validation. Because nearly all subjects in such research have been men, future investigations should focus on women and elucidate the feasibility of universal physical fitness tests for all that include measures of health- and work-related fitness while imposing no systematic body mass bias.

Strength training (ST) is an important health behavior for aging women; it helps maintain strength and function and reduces risk for chronic diseases. This study assessed change in physical fitness following participation in a ST program implemented and evaluated by community leaders. The StrongWomen Program is a nationally disseminated, research-based, community ST program active in 40 states. The Senior Fitness Test is used to assess upper and lower body strength, upper and lower body flexibility, aerobic fitness, and agility; data are collected prior to and following program participation. For these analyses, five states provided deidentified data for 367 female participants, mean age 63 (±11) years. Attendance in approximately 10 weeks of twice-weekly classes was 69.4%. Paired t tests were used to analyze pre-post change. Significant improvements were observed (p < .01) in all Senior Fitness Test measures. Data are stratified by age-group and compared with published, age-based norms. This study demonstrates that it is feasible for community leaders to conduct pre-post physical fitness evaluations with participants and that participants experienced improvements across several important domains of physical fitness.

Although the time spent sitting in motorized vehicles has been determined to be adversely associated with cardiometabolic health, its association with other health indicators remains unclear. This study examined associations between traveling by private motorized vehicle and 4 indicators of physical fitness in adults. Data from 52,114 Taiwanese adults aged 20 to 65 years who participated in the 2013 National Adults Fitness Survey were used. The examined variables were height, body mass, and performance in modified sit-and-reach (flexibility), bent-leg sit-up (abdominal muscular strength and endurance), and a 3-min step test (cardiorespiratory endurance). Participants were asked on how many days they had used a private car or motorcycle for traveling from place to place and categorized as non-, occasional, and daily private motorized vehicle travelers. Logistic and linear regression models were used to examine associations between the categories of using private motorized vehicles to travel and physical fitness performance. After an adjustment for potential demographic and behavioral confounders, daily traveling by private motorized vehicle was associated with a higher probability of overweight (odds ratio = 1.18), lower performance of abdominal muscular strength and endurance (-0.37 times/min), and lower cardiorespiratory fitness (-0.60 physical fitness index) than was traveling that did not involve private motorized vehicles. The results suggest that in addition to unfavorable cardiorespiratory fitness and a risk of overweight, daily traveling by private motorized vehicle is associated with poor performance in abdominal muscular strength and endurance.

To investigate the association between physical fitness, obesity, health related quality of life (HRQoL) and sleep disturbance in 463 community-dwelling older Spanish women (66-91 years of age). Cross-sectional study. Sleep disturbance was assessed with the Jenkins Sleep Scale. Active and sedentary behaviors were recorded by standardized questionnaires. HRQoL was assessed with the EuroQoL-5D. Anthropometric measurements were obtained using standardized techniques. Body fat was measured using bioelectrical impedance. Physical fitness was evaluated by a set of eight tests. Sleep disturbance was reported by 45.1% of women, being associated with higher body mass index (p fitness. Women in the upper tertile of fitness index had 92.0% lower risk of sleep disturbance as compared to the lower tertile (p = 0.08), while women in the highest tertile of upper body strength had 76.4% lower risk of sleep disturbance as compared to the lower tertile (p fitness and reduced HRQoL. Interventions involving weight management and improvement of physical fitness may contribute to better sleep quality in older women.

The purpose of this study was to assess the effects of 8 weeks of modified hatha yoga training on physical fitness and stress level in injured workers. Eighteen male and female injured workers, age between 18 and 55 years, participated in this study. They were divided into two groups: an additive hatha yoga training to routine industrial rehabilitation program group (HYG: n = 9) and a control group with no yoga training (CG: n = 9). A modified hatha yoga protocol was designed for this population by two certified yoga instructors, approved by a physical therapist, and conducted for 1 h, three times weekly for 8 weeks. Physical fitness variables including flexibility of lower back and hamstrings, hand grip strength and lung capacity and scores of sensitivity to stress were evaluated at the time of recruitment and after 8 weeks of intervention. The values of all physical fitness variables and stress scores were no significant difference between the two groups at baseline. Significant post-yoga improvements for HYG group were noted in flexibility, hand grip strength, and vital capacity (p Stress scores did not change as a result of hatha yoga training. An 8-week modified hatha yoga training experience exerted therapeutic effects on physical fitness variables including flexibility of lower back and hamstrings, hand grip strength and vital capacity, but not on stress level in injured workers. These findings indicate that hatha yoga can be a beneficial adjunct to routine physical therapy treatment in industrial rehabilitation programs.

Systemic lupus erythematosus (SLE) is an autoimmune disease that is characterized by fatigue; however, little research has been performed to identify non-pharmacological strategies, such as physical exercise, that can be employed in the prevention and treatment of fatigue in patients with SLE. Moreover, it is not clear whether physical fitness (defined here as cardiovascular fitness and muscle strength) and functional capacities are related to SLE-associated fatigue. Here, we review the studies, mechanisms and results that relate to SLE-associated fatigue. The main findings indicate that SLE patients have lower cardiovascular capacity than healthy subjects. Physical fitness, muscle strength and functional capacity are also lower in patients with SLE than in healthy individuals. The effects of exercise programs in reducing symptoms of fatigue in SLE patients remain unclear. Copyright © 2011 Elsevier B.V. All rights reserved.

The relationship between physical fitness and academic achievement has received much attention owing to the increasing prevalence of children who are overweight and unfit, as well as the inescapable pressure on schools to produce students who meet academic standards. This study examined 259 public school students in third and fifth grades and found that field tests of physical fitness were positively related to academic achievement. Specifically, aerobic capacity was positively associated with achievement, whereas BMI was inversely related. Associations were demonstrated in total academic achievement, mathematics achievement, and reading achievement, thus suggesting that aspects of physical fitness may be globally related to academic performance in preadolescents. The findings are discussed with regards to maximizing school performance and the implications for educational policies.

This study seeks to explore whether increased PA in school affects children's executive function and aerobic fitness. The "Active school" study was a 10-month randomized controlled trial. The sample included 449 children (10-11 years old) in five intervention and four control schools. The weekly interventions were 2×45 minutes physically active academic lessons, 5×10 minutes physically active breaks, and 5×10 minutes physically active homework. Aerobic fitness was measured using a 10-minute interval running test. Executive function was tested using four cognitive tests (Stroop, verbal fluency, digit span, and Trail Making). A composite score for executive function was computed and used in analyses. Mixed ANCOVA repeated measures were performed to analyze changes in scores for aerobic fitness and executive function. Analysis showed a tendency for a time×group interaction on executive function, but the results were non-significant F(1, 344)=3.64, P=.057. There was no significant time×group interaction for aerobic fitness. Results indicate that increased physical activity in school might improve children's executive function, even without improvement in aerobic fitness, but a longer intervention period may be required to find significant effects. © 2017 John Wiley & Sons A/S.

Psychosocial stress is a suggested risk for coronary heart disease (CHD). The relationship of stress resilience in adolescence with subsequent CHD risk is underinvestigated, so our objective was to assess this and investigate the possible mediating role of physical fitness. In this register-based study, 237,980 men born between 1952 and 1956 were followed from 1987 to 2010 using information from Swedish registers. Stress resilience was measured at a compulsory military conscription examination using a semistructured interview with a psychologist. Some 10,581 diagnoses of CHD were identified. Cox regression estimated the association of stress resilience with CHD, with adjustment for established cardiovascular risk factors. Low-stress resilience was associated with increased CHD risk. The association remained after adjustment for physical fitness and other potential confounding and mediating factors, with adjusted HRs (and 95% CIs) of 1.17 (1.10 to 1.25), with some evidence of mediation by physical fitness. CHD incidence rates per 1000 person-years (and 95% CIs) for low-stress, medium-stress and high-stress resilience were 2.61 (2.52 to 2.70), 1.97 (1.92 to 2.03) and 1.59 (1.53 to 1.67) respectively. Higher physical fitness was inversely associated with CHD risk; however, this was attenuated by low-stress resilience, shown by interaction testing (p stress resilience in adolescence was associated with increased risk of CHD in middle age and may diminish the benefit of physical fitness. This represents new evidence of the role of stress resilience in determining risk of CHD and its interrelationship with physical fitness. Published by the BMJ Publishing Group Limited.

Physical combat readiness of military personnel ensures maximal effectiveness of combat forces during wartime. Combat readiness has always been linked to the Army Physical Fitness Test (APFT). Each raw score is converted to a standard score and corrected for age and gender. There is no standard measurement to evaluate combat readiness in the Royal Thai Army. To determine standardized criteria for physical combat readiness of Royal Thai Army personnel through systematic review, the APFT was used to determine fitness levels and to promote health. To pass the test, each soldier in each unit must attain a minimal standard score for each individual subtest. At present, each unit in the armed forces derives its own standard, based on different missions. The APFT might be an acceptable method to measure physical combat readiness. However, no studies have established the general measurements to evaluate combat readiness.

Full Text Available Physical literacy is the degree of fitness, behaviors, knowledge, and fundamental movement skills (agility, balance, and coordination a child has to confidently participate in physical activity. Active video games (AVG, like the Nintendo Wii, have emerged as alternatives to traditional physical activity by providing a non-threatening environment to develop physical literacy. This study examined the impact of AVGs on children’s (age 6–12, N = 15 physical literacy. For six weeks children played one of four pre-selected AVGs (minimum 20 min, twice per week. Pre and post measures of motivation, enjoyment, and physical literacy were completed. Results indicated a near significant improvement in aiming and catching (p = 0.06. Manual dexterity significantly improved in males (p = 0.001, and females felt significantly less pressured to engage in PA (p = 0.008. Overall, there appears to be some positive impact of an AVG intervention on components of physical literacy.

Physical activity is known to influence sleep efficiency. Relatively little is known about the relationship between physical activity and sleep efficiency in young and older humans and the impact of exercise training on sleep efficiency in healthy older individuals. To determine the relationship between physical fitness and daily energy expenditure with sleep efficiency in young and older subjects, and assess the effect of 12-month exercise training on sleep efficiency in healthy older participants. The relationship between physical fitness (maximal cycling test) and daily energy expenditure (accelerometry) with sleep efficiency (accelerometry) was examined cross-sectionally in 12 healthy young adults (27 ± 5 years) and 21 healthy older participants (69 ± 3 years). Subsequently, the effect of 12-month exercise training (n = 11) or control period (n = 10) on sleep efficiency in older participants was examined using a randomized controlled trial. Daily energy expenditure and sleep efficiency did not differ between young and older subjects. A significant correlation was found between energy expenditure and sleep efficiency (r = 0.627, p = 0.029) in young adults, but not in older participants (r = -0.158, p = 0.49). Physical fitness did not correlate with sleep efficiency in either group. Exercise training significantly improved physical fitness (15.0%, p energy expenditure have greater sleep efficiency, whilst this relationship is diminished with advanced age. In contrast, we found no correlation between physical fitness and sleep characteristics in healthy young or older participants, which may explain the lack of improvement in sleep characteristics in older participants with 12-month exercise training. Exercise training may be more successful in subjects with existing sleep disturbances to improve sleep characteristics rather than in healthy older subjects. Copyright © 2012 S. Karger AG, Basel.

This study examined obesity and parameters of physical fitness in 178 elementary schoolchildren during an academic year as well as after the summer holidays. Results showed significant physical fitness improvements during the school year, with little or no changes in the summer holidays. Children who reported less than 30 minutes of daily participation in physical activity demonstrated lower prevalence rates for overweight and obesity as well as superior fitness performance. The detrimental effect of the summer break on the progress of physical fitness was less in children who did participate in physical activity than in those who did not. Longitudinal modelling using generalized estimating equations demonstrated that physical activity is a major contributing factor for obesity over time, masking the singular effect of various fitness parameters. It is concluded that pre-adolescent children advance in physical fitness mainly during the school year, with physical activity being a beneficial countermeasure for the development of obesity.

The physical demands imposed on contemporary dancers by choreographers and performance schedules make their physical fitness just as important to them as skill development. Nevertheless, it remains to be confirmed which physical fitness components are associated with aesthetic competence. The aim of this study was to: 1. replicate and test a novel aesthetic competence tool for reliability, and 2. investigate the association between selected physical fitness components and aesthetic competence by using this new tool. Seventeen volunteers underwent a series of physical fitness tests (body composition, flexibility, muscular power and endurance, and aerobic capacity) and aesthetic competence assessments (seven individual criteria commonly used by selected dance companies). Inter-rater reliability of the aesthetic competence tool was very high (r = 0.96). There were significant correlations between the aesthetic competence score and jump ability and push-ups (r = 0.55 and r = 0.55, respectively). Stepwise backward multiple regression analysis revealed that the best predictor of aesthetic competence was push-ups (R(2) = 0.30, p = 0.03). Univariate analyses also revealed that the interaction of push-ups and jump ability improved the prediction power of aesthetic competence (R(2) = 0.44, p = 0.004). It is concluded that upper body muscular endurance and jump ability best predict aesthetic competence of the present sample of contemporary dancers. Further research is required to investigate the contribution of other components of aesthetic competence, including upper body strength, lower body muscular endurance, general coordination, and static and dynamic balance.

Full Text Available ABSTRACT Introduction: Worldwide cocaine use in all its various forms is increasing; cocaine users exceeded 17 million in the world. In Brazil, this data is also alarming. A survey conducted in 2010 found that the country has more than 900,000 crack-cocaine users. Objective: To evaluate the effects of exercise on anthropometric variables and components of physical fitness in ex-crack cocaine users. Methods: Randomized controlled trial with 20 men, divided into exercise group (n=10 and control group (n=10, admitted to a detoxification center. We assessed the physical fitness components related to health (cardiorespiratory endurance, flexibility, muscular strength/endurance, and body composition before and after the physical training program. Results: The exercise contributed to the maintenance of anthropometric variables, while the control group had an increased in total body fat and visceral fat. Regarding physical fitness, resistance training led to the increase of most variables studied, particularly strength and cardiorespiratory capacity. On the other hand, the VO2max and the strength of the sedentary subjects were reduced (P<0.05. Conclusion: The exercise showed beneficial effects on the components of physical fitness and maintenance of body composition.

Full Text Available Abstract Background Burn injuries have a major impact on the patient’s physical and psychological functioning. The consequences can, especially in pediatric burns, persist long after the injury. A decrease in physical fitness seems logical as people survive burn injuries after an often extensive period of decreased activity and an increased demand of proteins leading to catabolism, especially of muscle mass. However, knowledge on the possibly affected levels of physical fitness in children and adolescents after burn injury is limited and pertains only to children with major burns. The current multidimensional study aims to determine the level of physical fitness, the level of physical activity, health-related quality of life and perceived fatigue in children after a burn injury. Furthermore, interrelations between those levels will be explored, as well as associations with burn characteristics. Methods/design Children and adolescents in the age range of 6 up to and including 18 years are invited to participate in this cross-sectional descriptive study if they have been admitted to one of the three Dutch burn centers between 6 months and 5 years ago with a burn injury involving at least 10% of the total body surface area and/or were hospitalized ≥ 6 weeks. Physical fitness assessments will take place in a mobile exercise lab. Quantitative measures of cardiorespiratory endurance, muscular strength, body composition and flexibility will be obtained. Outcomes will be compared with Dutch reference values. Physical activity, health-related quality of life and fatigue will be assessed using accelerometry and age-specific questionnaires. Discussion The findings of the current study will contribute to a better understanding of the long-term consequences of burn injury in children and adolescents after burns. The results can guide rehabilitation to facilitate a timely and optimal physical recovery. Trial registration The study is registered in

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 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.

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.

To examine the association between physical fitness, cardiac parasympathetic control, and inflammatory cytokine responses to mental stress. Exercise and physical fitness may act as a buffer to the detrimental effects of psychosocial stress exposure. Participants were 207 men and women (52 +/- 3 years) drawn from the Whitehall II epidemiological cohort. Participants completed two mental stressors consisting of a 5-minute Stroop task and a 5-minute mirror tracing task. Blood samples were obtained during baseline and 45 minutes post stress. Heart rate variability (HRV) was measured during baseline, stress, and recovery. Physical fitness was assessed from a submaximal exercise test. Interleukin (IL)-6 and IL-1 receptor antagonist were increased significantly at 45 minutes post stress. Multiple linear regression analysis, adjusted for age, body mass index, gender, smoking, alcohol, grade of employment, and basal levels of inflammatory markers demonstrated that exercise heart rate (a fitness indicator) was related to IL-6 (beta = 0.24; p = .005) and tumor necrosis factor (TNF)-alpha responses to stress (beta = 0.27; p = .002). Exercise heart rate was also related to the HRV response to stress (beta = -0.23; p = .02). A higher systolic blood pressure response to exercise was a predictor of TNF-alpha responses to stress (beta = 0.18; p = .03). Physical fitness (as indexed by lower exercise heart rate) is associated with smaller inflammatory cytokine responses to acute mental stress, an effect that may be partly mediated through parasympathetic pathways. This may be one of the mechanisms by which physical fitness confers protection against cardiovascular risk.

The aim of this study was to analyze the association between poor sleep quality with BMI and health-related physical fitness among college freshmen. The participants were college freshmen enrolled in 2011. Sleep quality was assessed using the Pittsburgh Sleep Quality Index (PSQI). A global PSQI score of 5 and total sleep time (TST) of 7 hours were used to differentiate between poor and good sleepers. Various Body Mass Index (BMI) ranges were used to categorize groups of underweight, normal weight and overweight. Health-related fitness was measured by Sit-And-Reach, Curl-Up, and Run/Walk Tests. A substantial proportion of college students were affected by poor sleep quality. Significantly more females were poor sleepers and had a TST shorter than 7 hrs. No difference in the proportions of participants categorized based on BMI between male and female students. Males generally scored better on health-related physical fitness tests than females. All results of physical fitness tests were significantly correlated with BMI, sleep quality (global PSQI), and TST in both males and females. Pool sleepers were associated with a higher BMI and lower performance of physical fitness. TST was negatively associated with BMI and time length to complete 1600-m or 800-m Run/Walk Test, and positively correlated with the performance of Sit-And-Reach and Curl-Up Tests in both genders. Poorer sleep quality and decreased TST were associated with lower performance in health-related physical fitness assessment among college students. Health promotion and educational programs for young adults should emphasize the importance of sleep quality and TST.

There is substantial evidence of rising prevalence of overweight and obesity and its co-morbidities among children in western-high income developed countries. In the European Union, the prevalence of overweight and obesity is increasing fastest among Polish children. Yet, there is paucity of evidence on the relationship of behavioral factors with body weight status of children in Poland. This study examined the association of obesity with physical fitness, physical activity, sedentary behavior and diet among Polish children. A total of 641 children (10-15 years) recruited from the Lower Silesia region of Poland participated in this cross-sectional study. Participants' anthropometrics, physical fitness, physical activity, sedentary behavior and dietary intake were assessed. Outcome variables were weight categories (according to body mass index [BMI], waist-to-hip ratio [WHR], and percentage body fat [% BF]). The strongest negative correlation was found between VO₂max and %BF ( r = -0.39, p children by 13%, 26% and 19%, respectively as compared to the group of obese children. VO₂max and weight and obesity indices were strongly correlated in both gender and age groups. Education and intervention programs to increase physical fitness (VO₂max) through aerobic training are recommended for Physical Education teachers, parents and children in order to reduce the rate of overweight and obesity among children in the Lower Silesia region of Poland.

The aim was to study the relationships between different domains of physical activity and cardiovascular risk factors and physical fitness. 781 young men participated. Self-reported leisure-time (LTPA), commuting (CPA) and occupational (OPA) activity were determined. Blood pressure, s-HDL-cholesterol, s-triglycerides and s-LDL-cholesterol, and glucose were measured. The continuous cardiovascular disease (CVD) risk factor score was calculated from the z-score mean of each cardiovascular risk factor. The cutpoint was defined as 1 standard deviation above the mean. Cardiorespiratory and muscular fitness were measured. The likelihood of CVD risk factor score was higher in moderate [OR 1.99 (95% CI 1.21-3.28)] and low [1.87 (1.16-3.02)] CPA groups compared with the high group, whereas neither low nor moderate LTPA or OPA groups showed similar associations after adjustments. Low OPA combined either with low LTPA [2.01 (1.08-3.74)] or low CPA [1.90 (1.05-3.44)] had a higher likelihood for CVD risk factor compared with combined moderate-high categories after adjustments. LTPA was positively associated with all physical fitness parameters, CPA with cardiorespiratory fitness and muscular endurance, and OPA with grip strength. The results emphasize the beneficial role of CPA regarding CVD risk factor score and stress the avoidance of low physical activity in its different domains.

Introduction: Cognitive impairment that affects older adults is commonly associated with an inflammatory imbalance, resulting in decreased physical fitness. Exercise has been pointed to mitigate immunosenescence and cognitive impairment associated with aging, while increase in physical fitness. However, few studies explored the relationship between changes in cytokine concentration and improvement on cognition due to elastic band strength training. The aim of this study was to investigate the effects of strength training on pro-and anti-inflammatory cytokines, hematological markers and physical fitness of older women with cognitive impairment. Methods: Thirty-three women (82.7 ± 5.7 years old) participated in the study and were divided in two groups: strength exercise training group (ST; n = 16) and Control Group (CG; n = 17) and were evaluated before and after 28 weeks of the exercise program. The CG did not undergo any type of exercise programs. Data for IL-10, TNF-α, IFN-γ, C-Reactive Protein (CRP), white blood counts (WBC), red blood counts (RBC), Mini Mental State Examination (MMSE) and physical fitness tests were analyzed in both moments. Results: IL-10 increased in the ST group without changes in CG. TNF-α and CRP increased in the control group while no changes were observed for IFN-γ in both groups. Strength training decreased leukocyte and lymphocyte counts and increase hemoglobin, mean cell volume and mean cell hemoglobin concentration. The MMSE score increased in strength training group but remained unchanged in the control group. A correlation between the variation of granulocyte counts and the MMSE scores was also observed within the total sample. An improvement in physical fitness was observed with strength training. Conclusion: Resistance exercise promoted better anti-inflammatory balance and physical performance simultaneously with an increase in cognitive profile in older women with cognitive impairment.

Rhabdomyolysis and myoglobinuric acute renal failure may occur following strenuous exercise and may be more common in less physically conditioned persons. A case of moderately severe acute renal failure after the exercise involved in a routine Army Physical Fitness Test (APFT) is described. This level of exertion, which is universally applied to Army personnel, should be recognized as a potential etiology of rhabdomyolysis. Prospective studies may help define the exact risk to renal function provided by the APFT.

Chromatography provides important detail on the composition of environmental samples and their chemical processing. However, the complexity of these samples and their tendency to contain many structurally and chemically similar compounds frequently results in convoluted or poorly resolved data. Data reduction from raw chromatograms of complex environmental data into integrated peak areas consequently often requires substantial operator interaction. This difficulty has led to a bottleneck in analysis that increases analysis time, decreases data quality, and will worsen as advances in field-based instrumentation multiply the quantity and informational density of data produced. In this work, we develop and validate an automated approach to fitting chromatographic data within a target retention time window with a combination of multiple idealized peaks (Gaussian peaks either with or without an exponential decay component). We compare this single-ion peak fitting approach to drawn baseline integration methods of more than 70,000 peaks collected by field-based chromatographs spanning across a wide range of volatilities and functionalities. Accuracy of peak fitting under real-world conditions is found to be within 10%. The quantitative parameters describing the fit (e.g. coefficients, fit residuals, etc.) are found to provide valuable information to increase the efficiency of quality control and provide constraints to accurately integrate peaks that are significantly convoluted with neighboring peaks. Implementation of the peak fitting method is shown to yield accurate integration of peaks otherwise too poorly resolved to separate into individual compounds and improved quantitative metrics to determine the fidelity of the data reduction process, while substantially decreasing the time spent by operators on data reduction.

Full Text Available Substantial evidence indicates that youth physical fitness levels are an important marker of lifestyle and cardio-metabolic health profiles and predict future risk of chronic diseases. The reliability physical fitness tests have not been explored in Latino-American youth population. This study's aim was to examine the reliability of health-related physical fitness tests that were used in the Colombian health promotion "Fuprecol study". Participants were 229 Colombian youth (boys n = 124 and girls n = 105 aged 9 to 17.9 years old. Five components of health-related physical fitness were measured: 1 morphological component: height, weight, body mass index (BMI, waist circumference, triceps skinfold, subscapular skinfold, and body fat (% via impedance; 2 musculoskeletal component: handgrip and standing long jump test; 3 motor component: speed/agility test (4x10 m shuttle run; 4 flexibility component (hamstring and lumbar extensibility, sit-and-reach test; 5 cardiorespiratory component: 20-meter shuttle-run test (SRT to estimate maximal oxygen consumption. The tests were performed two times, 1 week apart on the same day of the week, except for the SRT which was performed only once. Intra-observer technical errors of measurement (TEMs and inter-rater (reliability were assessed in the morphological component. Reliability for the Musculoskeletal, motor and cardiorespiratory fitness components was examined using Bland-Altman tests. For the morphological component, TEMs were small and reliability was greater than 95% of all cases. For the musculoskeletal, motor, flexibility and cardiorespiratory components, we found adequate reliability patterns in terms of systematic errors (bias and random error (95% limits of agreement. When the fitness assessments were performed twice, the systematic error was nearly 0 for all tests, except for the sit and reach (mean difference: -1.03% [95% CI = -4.35% to -2.28%].

Reduced physical fitness secondary to heart failure (HF) may contribute to poor driving; reduced physical fitness is a known correlate of cognitive impairment and has been associated with decreased independence in driving. No study has examined the associations among physical fitness, cognition, and driving performance in people with HF. Eighteen people with HF completed a physical fitness assessment, a cognitive test battery, and a validated driving simulator scenario. Partial correlations showed that poorer physical fitness was correlated with more collisions and stop signs missed and lower scores on a composite score of attention, executive function, and psychomotor speed. Cognitive dysfunction predicted reduced driving simulation performance. Reduced physical fitness in participants with HF was associated with worse simulated driving, possibly because of cognitive dysfunction. Larger studies using on-road testing are needed to confirm our findings and identify clinical interventions to maximize safe driving.

The DNA methylation-based 'epigenetic clock' correlates strongly with chronological age, but it is currently unclear what drives individual differences. We examine cross-sectional and longitudinal associations between the epigenetic clock and four mortality-linked markers of physical and mental fitness: lung function, walking speed, grip strength and cognitive ability. DNA methylation-based age acceleration (residuals of the epigenetic clock estimate regressed on chronological age) were estimated in the Lothian Birth Cohort 1936 at ages 70 (n = 920), 73 (n = 299) and 76 (n = 273) years. General cognitive ability, walking speed, lung function and grip strength were measured concurrently. Cross-sectional correlations between age acceleration and the fitness variables were calculated. Longitudinal change in the epigenetic clock estimates and the fitness variables were assessed via linear mixed models and latent growth curves. Epigenetic age acceleration at age 70 was used as a predictor of longitudinal change in fitness. Epigenome-wide association studies (EWASs) were conducted on the four fitness measures. Cross-sectional correlations were significant between greater age acceleration and poorer performance on the lung function, cognition and grip strength measures (r range: -0.07 to -0.05, P range: 9.7 x 10(-3) to 0.024). All of the fitness variables declined over time but age acceleration did not correlate with subsequent change over 6 years. There were no EWAS hits for the fitness traits. Markers of physical and mental fitness are associated with the epigenetic clock (lower abilities associated with age acceleration). However, age acceleration does not associate with decline in these measures, at least over a relatively short follow-up. © The Author 2015.

College students with a tendency toward attention deficit/hyperactivity disorder (ADHD) tend to act impulsively because they cannot control their behavior. They display low academic achievement and insufficient social skills, and are at high risk for alcoholism and drug abuse. Although various intervention methods have been used to reduce ADHD tendency (e.g., improving physical fitness and participating in sports and exercise), there are few studies on the relationship between ADHD and health-related physical fitness. Accordingly, this study explored the relationship between ADHD symptoms in college students and physical fitness. We measured health-related physical fitness and ADHD in 86 male college students using a self-report rating scale. The results showed the following. First, a significant relationship was found between ADHD tendency and inattention/memory problems, hyperactivity/restlessness, impulsivity/emotional lability, and abdominal fat. Push-ups were associated with ADHD tendency and the inattention/memory problems, hyperactivity/restlessness, impulsivity/emotional lability, and problems with self-concept subtests. Grip strength was significantly related to inattention/memory problems. Second, risk factors for ADHD tendency significantly increased for male college students with low muscular strength and endurance relative to those with greater muscular strength and endurance. Risk factors also significantly increased for male college students with high rates of abdominal obesity.

There is a growing consensus that bariatric surgery is currently the most efficacious and long-term treatment for clinically severe obesity. However, it remains to be determined whether poor physical fitness, an important characteristic of these patients, improves as well. The purpose of this pilot study is to investigate the effect of gastric bypass surgery on physical fitness and to determine if an exercise program in the first 4 months is beneficial. Fifteen morbidly obese patients (BMI 43.0 kg/m(2)) were tested before and 4 months after gastric bypass surgery. Eight of them followed a combined endurance and strength training program. Before and after 4 months the operation, anthropometrical characteristics were measured, and an extensive assessment of physical fitness (strength, aerobic, and functional capacity) was performed. Large-scale weight loss through gastric bypass surgery results in a decrease in dynamic and static muscle strength and no improvement of aerobic capacity. In contrast, an intensive exercise program could prevent the decrease and even induced an increase in strength of most muscle groups. Together with an improvement in aerobic capacity, functional capacity increased significantly. Both groups evolved equally with regard to body composition (decrease in fat mass and fat-free mass). An exercise training program in the first 4 months after bariatric surgery is effective and should be promoted, considering the fact that physical fitness does not improve by weight loss only.

Full Text Available Purpose: The aim of the study was to evaluate the somatic development and comprehensive physical fitness of artistic gymnasts aged 7-10 years. Materials and methods: Gymnasts (n = 307, split up into four age groups performed eight Eurofit tests. The results were evaluated in points according to the development standards prepared in scale T for the Polish girls population. Results : The gymnasts obtained the highest growth rate in balance test - FLB (13 points, arm and shoulder muscular endurance test - BAH (7 points and speed of the upper limb movement test - PLT (4 points out of eight physical fitness tests. Conclusions. High and very high level of performance in the six Eurofit tests and increased total number of points in the subsequent age groups of artistic gymnasts proved high effectiveness of training in shaping the key components of a comprehensive physical fitness in artistic gymnastics - balance, strength, endurance, speed and flexibility. Relatively little progress in isometric hand strength (HGR and standing broad jump (SBJ suggests a significant influence of genetic factors on the level of these abilities. The results provide an objective information useful in optimizing control system of training effects in comprehensive physical fitness and optimization of artistic gymnasts training at the comprehensive stage of sports training.

Full Text Available Abstract Background Substantial evidence indicates that children’s physical fitness levels are markers of their lifestyles and their cardio-metabolic health profile and are predictors of the future risk of chronic diseases such as obesity, cardiometabolic disease, skeletal health and mental health. However, fitness reference values for ethnic children and adolescents have not been published in a Latin-American population. Therefore, the aim of the study was to provide sex- and age-specific physical fitness and anthropometric reference standards among Colombian-Indian schoolchildren. Methods A sample of 576 participants (319 boys and 257 girls aged 10 to 17 years old was assessed using the FUPRECOL test battery. Four components of physical fitness were measured: 1 morphological component: height, weight, body mass index (BMI, waist circumference (WC, triceps skinfold, subscapular skinfold, and body fat (%; 2 musculoskeletal component: handgrip and standing long jump test; 3 motor component: speed/agility test (4 × 10 m shuttle run; and 4 cardiorespiratory component: course-navette 20 m, shuttle run test and estimation of maximal oxygen consumption by VO2max indirect. Centile smoothed curves for the 3rd, 10th, 25th, 50th, 75th, 90th and 97th percentiles were calculated using Cole’s LMS method. Results Our results show that weight, height and BMI in each age group were higher in boys than in girls. In each groups, age showed a significant effect for BMI and WC. Boys showed better than girls in cardiorespiratory fitness, lower- and upper-limb strength and speed/agility and girls performed better in low back flexibility. Conclusion Our results provide for the first time sex- and age-specific physical fitness and anthropometric reference values for Colombian Nasa Indian children and adolescents aged 10–17.9 years.

Full Text Available Objective: to evaluate the level of physical activity, cardiorespiratory fitness and nutritional status of Brazilian higher education institution servers. Method: 134 public servants (80 men and 54 women were evaluated to estimate body mass index (BMI, waist circumference (WC, waist/hip ratio (WHR, aerobic fitness and blood pressure at rest. Results: most of the servers were classified as insufficiently active (62%. BMI results show a high prevalence of obesity (39% mild and 33% moderate. WC showed a prevalence of high (30% and very high risk (27%, and WHR showed a prevalence of high (28% or very high risk (12%. The ergometric test showed that 41% of the servers presented very poor (17% or poor (24% aerobic fitness and 23%, regular aerobic fitness. Considering blood pressure, 15% of the servers presented blood pressure considered as borderline and 30% considered as hypertension. No associations were found between physical condition (active or inactive with WC (χ2 = 3.4, p = 0.179, WHR (χ2 = 7.0, p = 0.073, aerobic fitness (χ2 = 4.3, p = 0.368 and blood pressure (χ2 = 2.9, p = 0.734. Although no association was observed between physical activity and BMI (χ2 = 7.6, p = 0.062, significance values (p < 0.07 suggested an association trend, with worse ratings for the sedentary group. Closing remarks: among higher education institution servers, there is high prevalence of physical inactivity, obesity and risk factors, and the majority of the sample had aerobic fitness below recommended levels.

To evaluate whether a change in fitness is associated with academic outcomes in New York City (NYC) middle-school students using longitudinal data and to evaluate whether this relationship is modified by student household poverty. This was a longitudinal study of 83,111 New York City middle-school students enrolled between 2006-2007 and 2011-2012. Fitness was measured as a composite percentile based on three fitness tests and categorized based on change from the previous year. The effect of the fitness change level on academic outcomes, measured as a composite percentile based on state standardized mathematics and English Language Arts test scores, was estimated using a multilevel growth model. Models were stratified by sex, and additional models were tested stratified by student household poverty. For both girls and boys, a substantial increase in fitness from the previous year resulted in a greater improvement in academic ranking than was seen in the reference group (girls: .36 greater percentile point improvement, 95% confidence interval: .09-.63; boys: .38 greater percentile point improvement, 95% confidence interval: .09-.66). A substantial decrease in fitness was associated with a decrease in academics in both boys and girls. Effects of fitness on academics were stronger in high-poverty boys and girls than in low-poverty boys and girls. Academic rankings improved for boys and girls who increased their fitness level by >20 percentile points compared to other students. Opportunities for increased physical fitness may be important to support academic performance. Copyright © 2014 Society for Adolescent Health and Medicine. Published by Elsevier Inc.

Full Text Available Abstract Background Leisure-time physical activity (LTPA and cardiorespiratory fitness contribute to mental health. Hopelessness has been linked to impaired mental health, cardiovascular events and mortality. Previous studies have focused on physical exercise and depression. We examined the associations of LTPA and cardiorespiratory fitness with feelings of hopelessness. Methods In this cross-sectional study leisure-time physical activity, maximal oxygen uptake (VO2max, hopelessness and cardiovascular risk factors were assessed in a population-based cohort of 2428 men aged 42 – 60 years old at baseline. Results Men feeling more hopeless about their future and reaching goals were less physically active, less fit and had a higher prevalence of many cardiovascular risk factors than men with lower levels of hopelessness. In a logistic regression model adjusted for age, smoking, alcohol consumption, cardiovascular disease and socioeconomic status, men engaging in less than 60 min/week of moderate-to-vigorous LTPA were 37% (95% CI 11 – 67% more likely to feel hopeless than those engaging in at least 2.5 h/wk of LTPA. After further adjusting for elevated depressive symptoms the association of LTPA and hopelessness remained significant. VO2max was also associated with hopelessness, but not after adjustment for depressive symptoms. Conclusion Moderate and vigorous LTPA and cardiorespiratory fitness were inversely associated with hopelessness in these middle-aged men. These findings suggest that physical inactivity and poor cardiorespiratory fitness is an important associate of hopelessness, a distinct element of low subjective well-being.

Fisherwomen contribute significantly to the coastal economy of Eastern India; however, data about their physical fitness and weight status are scant. The present cross-sectional study was designed to investigate cardiorespiratory fitness and weight status of fisherwomen, which may be influenced by their occupational workload, using morphometric and anthropometric measures. The study was conducted among young fisherwomen (mean age 23.7 years) randomly selected from Araku, Visakhapatnam, Andhra Pradesh, and among young women who are not engaged in the fishing industry but are residents of Araku, who served as controls (mean age 21.3 years). Measurements of body composition included several anthropometric variables, while physical efficiency parameters included a physical fitness index (PFI), VO2max, total energy expenditure, and anaerobic capacity. A significant difference (pfitness index, total energy expenditure, and anaerobic power was found in fisherwomen compared with controls. Analysis of collected data showed that the majority of the fisherwomen studied have a normal range of BMI (42%), but 6% of them were found to be mildly overweight. They also showed lower fat mass (13.5 [ ± 3.87]kg) and lower waist-to-hip ratio (WHR) and conicity index. Additionally, they were found to have a moderate level of physical fitness (64.3 [ ± 1.97]%) and a higher total energy expenditure (4.92 [ ± 0.52]k.cal.min(-2)). This study implies that physical fitness and weight status of young fisherwomen in Eastern India are influenced by their occupational workload. Copyright © 2014 Ministry of Health, Saudi Arabia.

Full Text Available Studies of the effects of physical fitness on cognition suggest that exercise can improve cognitive abilities in healthy older adults, as well as delay the onset of age-related cognitive decline. The mechanisms for the positive benefit of exercise and how these effects interact with other variables known to influence cognitive function (e.g., involvement in cognitive activities are less well understood. The current study examined the associations between the physical fitness, cerebrovascular blood flow regulation and involvement in cognitive activities with neuropsychological function in healthy postmenopausal women. Methods: Forty-two healthy women between the ages of 55 and 90 were recruited. Physical fitness (V˙ o2max, cerebrovascular reserve (cerebral blood flow during rest and response to an increase in end-tidal (i.e., arterial PCO2, and cognitive activity (self-reported number and hours of involvement in cognitive activities were assessed. The association of these variables with neuropsychological performance was examined through linear regression. Results: Physical fitness, cerebrovascular reserve and total number of cognitive activities (but not total hours were independent predictors of cognitive function, particularly measures of overall cognitive performance, attention and executive function. In addition, prediction of neuropsychological performance was better with multiple variables than each alone. Conclusions: Cognitive function in older adults is associated with multiple factors, including physical fitness, cerebrovascular health and cognitive stimulation. Interestingly, cognitive stimulation effects appear related more to the diversity of activities, rather than the duration of activity. Further examination of these relationships is ongoing in a prospective cohort study.

The sample comprised 326 people (132 men and 194 women who did not perform regular physical exercise, and who were separated for analysis by sex and into three age groups: 20-29 years (G1, 30-39 years (G2 and 40-49 years (G3. All subjects underwent anthropometric measurements and motor performance testing (flexibility, muscle resistance/strength and cardiorespiratory fitness. Statistical analysis employed the Levene test to verify the homogeneity of variation, descriptive statistics, single factor ANOVA (age group and the Bonferroni test. The significance level adopted was p<0.05. The best levels of physical fitness were observed among the youngest subjects (G1, irrespective of sex, while the worst fitness levels were detected in the oldest subjects (G3. The variation in body fat from G1 to G3 was more accentuated among the men (34% than among the women (16%. With relation to motor performance, the greatest percentage differences between G1 and G3 were detected by either modified abdominal test (39%and 22%, for men and women respectively and the arm flexion and extension test(31% and 24%, for men and women respectively. The results suggest that among individuals who do not regularly practice physical exercise there is a natural tendency for health related physical fitness to reduce as age increases.

The aim of this study was verify physical activity practice and associated factors among FZ users of Pelotas. Participants answered a questionnaire containing demographic, socioeconomic, behavioral, health and on the use of FZs. A long version of the International Physical Activity Questionnaire was used to determine the level of physical activity and those who reported at least 150 minutes / week of PA in the leisure time were considered sufficiently active. The study included 323 subjects (65.3% women, mean age 52.5 years, 83.6% white skin color and 61.9% married. Almost half of respondents were overweight (48.0%, 45.8% had high blood pressure, 10.5% had diabetes and 64.4% used medications. About 77.7% of respondents were classified as sufficiently active. Health perception was associated to leisure physical activity, and the better the health perception, the higher the prevalence of sufficient physical activity. Collective programs with participation of Physical Education teacher can contribute to interaction of practitione with the use of fitness zones and increase the level of physical activity of individuals.

Incarceration has been associated with reduced physical activity. However, physical inactivity is a major cause of morbidity and mortality. The aim of the present study was therefore, to evaluate the incidence and relationship between the measures of physical fitness and the duration of incarceration in of inmates in Kano-Nigeria prisons. A cross-sectional study was done to determine the relationship between the measures of physical fitness and the duration of incarceration of inmates in Kano prisons. Subjects' physical fitness level (cardio-respiratory fitness, body mass index and waist circumference) was assessed using standardized protocols. Simple percentage, Pearson moment correlation test and student's t-test were used to analyze variables of interest. One hundred and sixteen inmates; 108 (93.1%) males and 8 (6.9%) females participated in the study. The study revealed high (93.1%) prevalence of low cardio-respiratory fitness among inmates and significant correlation between the selected indices of physical fitness (cardio-respiratory fitness, body mass index and waist circumference) and duration of incarceration. The prevalence of low cardio-respiratory fitness was high among inmates and long period of inadequate physical activity may be implicated as causative factor of low physical fitness among inmates in Kano prison. Prison administration and staff should encourage healthy inmate behavior. Provision of adequate facilities to encourage physical activity and sports participation is highly needed.
