    3374 accidents occurring on the field of sport during the years 1975--1977 accounted for 19% of all accidents dealt with at the Institute of Kinderchirurgie in Graz. 51% of the accidents were caused by the typical winter sports: skiing, tobogganing, ice-skating and ski-jumping with skiing accounting for 75% of the accidents. The fracture localization typical of the different kinds of winter sport is dealt with in detail. The correct size and safety of the equipment were found to be particularly important in the prevention of such accidents in childhood.

    During the last winter season, some fatal sport injuries with severe traumatic brain injury (TBI) prompted major discussions about protective helmet use. Although ski helmets reportedly lead to a 60% decrease of risk to incur TBI, little is known about the distribution of helmet users and which factors are crucial for the decision to wear a helmet. Especially, it is unknown whether knowledge or experience concerning TBI in winter sports influences the use of helmets, as well as the attitude and opinion of people. Since treatment of TBI is a major field in neurosurgery, 55 neurosurgical departments (NS) in Germany, Switzerland and Austria were addressed and asked to answer anonymous questionnaires. A "non-trauma-educated" control cohort (NTP) was interviewed in ski resorts in Austria as well as sports equipment stores in Germany. Questionnaires were returned by 465 NS and 546 NTP. Half of NS and NTP wore helmets in winter sports. Although some interviewees showed cognitive dissonant behaviour, experience in TBI after ski or snowboard accidents significantly affected the decision to wear helmets. After the fatal ski accidents, and increased media coverage 15.4% NS and 13.2% NTP bought their helmet. Furthermore, incidence of helmet use in children was correlated with the actual use and disposition of their parents to make the use of helmet compulsory. This study indicates that brain-trauma education affects ones attitude and opinion concerning protective helmet use in winter sports. However, without neglecting educational measures, emotional arguments should be added in the promotion of helmets to make them a popular integral part of winter sport outfits.

    The Engineering Approach to Winter Sports presents the state-of-the-art research in the field of winter sports in a harmonized and comprehensive way for a diverse audience of engineers, equipment and facilities designers, and materials scientists. The book examines the physics and chemistry of snow and ice with particular focus on the interaction (friction) between sports equipment and snow/ice, how it is influenced by environmental factors, such as temperature and pressure, as well as by contaminants and how it can be modified through the use of ski waxes or the microtextures of blades or ski soles. The authors also cover, in turn, the different disciplines in winter sports:  skiing (both alpine and cross country), skating and jumping, bob sledding and skeleton, hockey and curling, with attention given to both equipment design and on the simulation of gesture and  track optimization.

    Full Text Available Realisation of sport activities always demanded certain conditions. Among those, sports facilities are certainly necessary. Since there were important changes in the process of training itself and successful performance, as well as, the results achieved by the sportsmen; there is a need for adequate sports facilities, that include whole variety of systems,equipment and necessities. Nowadays, Sport facilities are not only “the place of event”, but also a condition/necessity in achieving best sport results. It is demanded that these facilities are comfortable, absolutely secure and that they can accommodate transmissions: an opening, the course of sports activities and the announcement of the winner. The kind of sport activity, age, sex; so the “sports level” of the competitors is emphasising the specific demands to wards sports facilities.

    Climate- or holiday-related seasonality in hospital admission rates is well known for many diseases. However, little research has addressed the impact of tourism on seasonality in admission rates. We therefore investigated the influence of tourism on emergency admission rates in Switzerland, where winter and summer leisure sport activities in large mountain regions can generate orthopedic injuries. Using small area analysis, orthopedic hospital service areas (HSAo) were evaluated for seasonality in emergency admission rates. Winter sport areas were defined using guest bed accommodation rate patterns of guest houses and hotels located above 1000 meters altitude that show clear winter and summer peak seasons. Emergency admissions (years 2000-2002, n = 135'460) of local and nonlocal HSAo residents were evaluated. HSAo were grouped according to their area type (regular or winter sport area) and monthly analyses of admission rates were performed. Of HSAo within the defined winter sport areas 70.8% show a seasonal, summer-winter peak hospital admission rate pattern and only 1 HSAo outside the defined winter sport areas shows such a pattern. Seasonal hospital admission rates in HSAo in winter sport areas can be up to 4 times higher in winter than the intermediate seasons, and they are almost entirely due to admissions of nonlocal residents. These nonlocal residents are in general -and especially in winter- younger than local residents, and nonlocal residents have a shorter length of stay in winter sport than in regular areas. The overall geographic distribution of nonlocal residents admitted for emergencies shows highest rates during the winter as well as the summer in the winter sport areas. Small area analysis using orthopedic hospital service areas is a reliable method for the evaluation of seasonality in hospital admission rates. In Switzerland, HSAo defined as winter sport areas show a clear seasonal fluctuation in admission rates of only nonlocal residents, whereas

    To highlight and discuss the considerations for the future development of equipment standards for Winter Paralympic sports. Literature searches were performed (in English) during May 2011 using the key words "technology, winter sport, Olympic, and Paralympic" in the computerized databases PubMed, PsycINFO, Science Direct, and Google Scholar. In addition, personal scientific observations were made at several Winter Paralympic Games. The retrieved articles were screened and assessed for relevance to the biological, biomechanical, and sport medicine aspects of equipment. There are 3 key areas in which technology has influenced sports performance in Paralympic winter sports, namely, specialized prostheses, crutch skis or outriggers (in lieu of poles), and sport-specific wheelchairs (such as the sit-ski). From a sport medicine perspective, a crucial factor not considered in the standard laboratory test of mechanical efficiency is the influence of the human-equipment connection, such as the stump-to-prosthesis interface or the required human-to-wheelchair control. This connectivity is critical to the effective operation of the assistive device. When assessing the efficiency of this equipment, the not-so-obvious, holistic, compensatory factors need to be considered. Assistive equipment is fundamental for a person with a disability to participate and compete in winter sport activities. Although there have been improvements in the mechanical function of some assistive devices, the key issue is matching the residual function of the person with the assistive equipment. Equitable access to this technology will also ensure that the fundamental spirit of fair play that underpins the Paralympic Games is maintained.

  7. SPORTS ACTIVITIES SPONSORSHIP

    Full Text Available Sports and economy have discovered each other, hoping to serve common interests. In view of transferring in a more efficient way the information about their products or services to consumers, the business operator finances sports activities for advertising purposes. A company involved in sports sponsorship can instantly transmit the message about its products to millions of potential buyers, thus increasing the market share and hence the profit that it generates. By sponsoring sport it is meant any agreement / convention, under which one party the sponsor makes available to the beneficiary the material resources, financial and / or other benefits in exchange for its association with a sport or sportsman and especially the promise to use this association with sport or sportsman for the purpose of advertising, especially TV advertising. The growing use of athletes as spokespersons for a product is largely due to the ability of athletes to attract public attention and the credibility they enjoy.

    Full Text Available Purpose: The aim of this research was to record and the evolution of the winter paralympic games and sports since 1976 until 2010. The history of the Winter Paralympic Games is relatively recent compared to that one of the Olympic Games. The first Games were held in 1976 in Ornskoldsvik, Sweden and the most recent, 38 years later in 2014, in Sochi, Russia. This article will examine the Winter Paralympic Games up until the ones in 2010 in Vancouver, Canada. During these years, there have been many changes in relation to the Games itself, the governing body of the Paralympic Movement, the sports’ facilities, the sports involved and sports’ categories. The motivation for writing this paper was the need to record and gather all of these items in one paper. Gathering information for the Winter Paralympic Games will be an important theoretical background. This information will create a database for the structure of the governing body of the Paralympic Games, for the organization of the Games [Local Organizing Committee (LOC, venues and equipment], for the evolution of the Winter Paralympic Sports and the categories of the athletes, as well as the evolution of the athletes’ and sports’ participation. Material : The research material that was used was mainly from the bibliography and records of the International Paralympic Committee (IPC, from the Official Post Games Reports and the Internet, while the research method that was used was descriptive. Moreover, the use of diagrams will depict the distribution of the participation of athletes and countries in each Games. Results : The participation of countries grew continuously and steadily from 16 to 44, during the years of 1976 to 2010 respectively. Regarding the athletes’ participation, starting in the first Games with 198 athletes, they reached the number of 502 in the 2010 Vancouver Winter Paralympic Games. The participation percentages of the athletes coming from Europe constituted the bulk

    Ice samples, after sliding against a steel runner, show evidence of recrystallization and microcracking under the runner, as well as macroscopic cracking throughout the ice. The experiments that produced these ice samples are designed to be analogous to sliding in the winter sport of skeleton. Changes in the ice fabric are shown using thick and thin sections under both diffuse and polarized light. Ice drag is estimated as 40-50% of total energy dissipation in a skeleton run. The experimental results are compared with visual inspections of skeleton tracks, and to similar behaviour in rocks during sliding on earthquake faults. The results presented may be useful to athletes and designers of winter sports equipment.This article is part of the themed issue 'Microdynamics of ice'. © 2016 The Author(s).

    There has been much debate about the potential impact of the Olympics. The purpose of this study was to determine if hosting the 2010 Vancouver Olympic Games (OG) encouraged Canadian children to be physically active. Children 5-19 years (n = 19862) were assessed as part of the representative Canadian Physical Activity Levels Among Youth surveillance study between August 2007 and July 2011. Parents were asked if the child participated in organized physical activity or sport. In addition, children wore pedometers for 7 days to objectively provide an estimate of overall physical activity. Mean steps/day and percent participating in organized physical activity or sport were calculated by time period within year for Canada and British Columbia. The odds of participation by time period were estimated by logistic regression, controlling for age and sex. Mean steps were lower during the Olympic period compared with Pre- (607 fewer steps/day 95% CI 263-950 steps/day) and Post-Olympic (1246 fewer steps 95% CI 858-1634 steps) periods for Canada. There was no difference by time period in British Columbia. A similar pattern in mean steps by time period was observed across years, but there were no significant differences in activity within each of these periods between years. The likelihood of participating in organized physical activity or sport by time period within or across years did not differ from baseline (August-November 2007). The 2010 Olympic Games had no measurable impact on objectively measured physical activity or the prevalence of overall sports participation among Canadian children. Much greater cross-Government and long-term efforts are needed to create the conditions for an Olympic legacy effect on physical activity.

    Identification of high-risk sports, including their most common and severe injuries and illnesses, will facilitate the identification of sports and athletes at risk at an early stage. To analyse the frequencies and characteristics of injuries and illnesses during the XXI Winter Olympic Games in Vancouver 2010. All National Olympic Committees' (NOC) head physicians were asked to report daily the occurrence (or non-occurrence) of newly sustained injuries and illnesses on a standardised reporting form. In addition, the medical centres at the Vancouver and Whistler Olympic clinics reported daily on all athletes treated for injuries and illnesses. Physicians covering 2567 athletes (1045 females, 1522 males) from 82 NOCs participated in the study. The reported 287 injuries and 185 illnesses resulted in an incidence of 111.8 injuries and 72.1 illnesses per 1000 registered athletes. In relation to the number of registered athletes, the risk of sustaining an injury was highest for bobsleigh, ice hockey, short track, alpine freestyle and snowboard cross (15-35% of registered athletes were affected in each sport). The injury risk was lowest for the Nordic skiing events (biathlon, cross country skiing, ski jumping, Nordic combined), luge, curling, speed skating and freestyle moguls (less than 5% of registered athletes). Head/cervical spine and knee were the most common injury locations. Injuries were evenly distributed between training (54.0%) and competition (46.0%; p=0.18), and 22.6% of the injuries resulted in an absence from training or competition. In skeleton, figure and speed skating, curling, snowboard cross and biathlon, every 10th athlete suffered from at least one illness. In 113 illnesses (62.8%), the respiratory system was affected. At least 11% of the athletes incurred an injury during the games, and 7% of the athletes an illness. The incidence of injuries and illnesses varied substantially between sports.

    During 1964-1974 112 injuries of the urogenital tract caused by winter sports were treated at the University Hospital Innsbruck, Department of Urology. Eighty-eight patients suffered skiing injuries, 20 tobogganing injuries, and one injury each was caused by ski jumping and bobsleighing accidents, two traumas resulted from a fall from a chair lift. On the basis of typical case reports the most common types of trauma of the urogenital tract are demonstrated and the basic mechanisms of the accidents are discussed. Particular attention is paid to the obvious increase of lesions of the external genitalia and the urethra in the last few years caused by the so-called spinning ski, as well as the frequency of kidney traumas, especially in winters with little snow. Tobogganing accidents caused injuries to the kidneys as well as to bladder and urethra. In contrast to traumas caused by skiing, tobogganing injuries were mostly multiple. Analysis of patients records shows an increase of these injuries, which were really not typical for winter sports. The possible reasons as well as their prevention are discussed.

    The aim of this study was to examine attitudes of winter sport participants toward a ski helmet mandatory. In total, 959 persons who had to estimate statements regarding ski helmet and helmet mandatory with the aid of a five level Likert scale were interviewed. About 85 % of interviewed persons totally agreed that a ski helmet reduces head injury risk although only 64 % are wearing a ski helmet. Significant more helmet wearers and females compared to non-wearers and males totally agreed that all winter sport participants should wear ski helmets on slopes as well as that all children on slopes should wear a ski helmet. Also, significant more helmet wearers and females compared to non-wearers and males totally agreed that a ski helmet mandatory for all people has to be recommended as well as that a ski helmet mandatory for children under 16 years has to be recommended. However, the acceptance for a helmet mandatory for all people as well as for children was significantly lower compared to recommendations for helmet use irrespective of helmet use or gender. Therefore, we conclude that preventive helmet campaigns possibly attain a higher acceptance leading to a higher helmet use compared to a helmet mandatory. © Georg Thieme Verlag KG Stuttgart · New York.

    Tibial plateau fractures overall and especially in winter sports are rare. However, the incidence in recent years is increasing. In a retrospective study from 2009-2012, we found 52 injuries affiliated with winter sports. Noticeable was the high rate of severe injury patterns. In 20 of the 52 cases, there were complete articular or bicondylar fractures (38 %). In 25 cases (48 %), fragment dislocation corresponding to the Moore classification was observed. The operative algorithm was based on the initial soft tissue damage and the type of fracture. A two or more stage procedure with first line soft tissue management and temporary external fixation stabilization was performed 12 times. The final internal osteosynthesis was based on the morphology of the fracture, i.e., direct exposition and stabilization of relevant fracture patterns. In 24 cases (46 %), there was a need for two (or more) approaches. In the anterior aspect of the tibial head, customary implants were used; posterior pathologies were stabilized with low-dimension implants. Summarizing with regard to the literature, there is a more discriminating view of tibial plateau fractures, regarding all relevant fracture patterns. Thus, different options in operative access and choice of implants can be made.

  16. Altitude training considerations for the winter sport athlete.

    Winter sports events routinely take place at low to moderate altitudes, and nearly all Winter Olympic Games have had at least one venue at an altitude >1000 m. The acute and chronic effects of altitude can have a substantial effect on performance outcomes. Acutely, the decline in oxygen delivery to working muscle decreases maximal oxygen uptake, negatively affecting performance in endurance events, such as cross-country skiing and biathlon. The reduction in air resistance at altitude can dramatically affect sports involving high velocities and technical skill components, such as ski jumping, speed skating, figure skating and ice hockey. Dissociation between velocity and sensations usually associated with work intensity (ventilation, metabolic signals in skeletal muscle and heart rate) may impair pacing strategy and make it difficult to determine optimal race pace. For competitions taking place at altitude, a number of strategies may be useful, depending on the altitude of residence of the athlete and ultimate competition altitude, as follows. First, allow extra time and practice (how much is yet undetermined) for athletes to adjust to the changes in projectile motion; hockey, shooting, figure skating and ski jumping may be particularly affected. These considerations apply equally in the reverse direction; that is, for athletes practising at altitude but competing at sea level. Second, allow time for acclimatization for endurance sports: 3-5 days if possible, especially for low altitude (500-2000 m); 1-2 weeks for moderate altitude (2000-3000 m); and at least 2 weeks if possible for high altitude (>3000 m). Third, increase exercise-recovery ratios as much as possible, with 1:3 ratio probably optimal, and consider more frequent substitutions for sports where this is allowed, such as ice hockey. Fourth, consider the use of supplemental O(2) on the sideline (ice hockey) or in between heats (skating and Alpine skiing) to facilitate recovery. For competitions at sea

    Objective To analyse the incidence of diseases and injuries suffered by athletes participating in the 27th Winter Sports Universiade held in Granada, Spain. Methods The daily occurrence of injuries and diseases was registered at the point of first aid (Borreguiles, 2665 metres above sea level (masl)) and in the clinic of Pradollano (2017 masl), both in Sierra Nevada, as well as in medical services provided by the organising committee of Granada 2015 Universiade and located in sport pavilions in which indoor competitions are held. Results A total of 1109 athletes (650 men, 58.61%; 459 women, 41.39%). Nine diseases and 68 injuries were recorded. In total, the rate of injury was 6.13% (7.07% for men and 4.79% for women). The percentage of injury was highest in alpine skiing (10.34%) followed by freestyle skiing (8.62%). In relation to the time of exposure, freestyle skiing showed the shortest time of exposure (0.31 hours) before suffering an injury. Short track speed skating showed the longest exposure (9.80 hours), before suffering an injury. The most common anatomical areas of injury were the head, shoulder and knee (13.23%). Only nine diseases were suffered (four women and five men) of which six were infections, one was a friction burn, one was a lipothymy and one a cluster headache due to height. Conclusion In general, 6.13% of the athletes sustained at least one injury and 0.81% a disease, which is a much lower percentage than that recorded in similar events. The incidence of injuries and diseases varied among sport specialities. PMID:28879023

    The 22nd Student World Winter Games took place in January 2005 in Innsbruck and Seefeld, Austria. Exactly 1,500 athletes of 50 nationalities competed in 69 events in ten winter sports. A total number of 750 functionaries, 800 volunteers and 85,000 spectators participated in the second largest winter sports event behind the Olympic winter games. The aim of this study was to evaluate the needed resources to ensure traumatological care for an event of that size. At the medical "call-center" all consultations, as well as patient data, diagnosis, and medical treatment were recorded using a preset protocol. Further, all patients treated in the University Hospital Innsbruck were registered with an emphasis on trauma patients. Forty-eight of 65 patients transported to the hospital as a result of the Universiade were trauma patients, 37 of whom were athletes. The gender distribution was 34:14 (m:f). Ice hockey players had the highest rate of injury (25% of all injured athletes), followed by alpine skiers (20.8% of injured athletes). The highest ISS was nine. Forty-three patients got ambulatory treatment, five were admitted to the hospital and surgical treatment was conducted in three cases. Mean patient number was 4.8 per day. No additional personnel, structural, or technical hospital resources were needed to accommodate a large winter sports event like the Universiad. Thus, a level-B trauma center with an emergency room and independent traumatological department with around the clock surgical capability seems to be sufficient to provide traumatological care for an event of this size if the possibility of patient transport to a larger facility exists in the case of catastrophic events.

Mean blood serum retinol level was 15% higher the upper limit of the norm (80 mcg/dl) in biathletes while median reached 90.9 mcg/dl. Blood serum level of tocopherols (1.22 +/- 0.03 mg/dl), ascorbic acid (1.06 +/- 0.03 mg/dl), riboflavin (7.1 +/- 0.4 ng/ml), and beta-carotene (25.1 +/- 1.7 mcg/dl) was in within normal range, but the incidence of insufficiency of vitamins E, C, B2, and carotenoid among athletes varied in the range of 0-25, 0-17, 15-67 and 42-75%, respectively. 95% of adults and 80% of younger athletes were sufficiently provided with vitamin E. Vitamin E level in blood serum of juniors involved in skeleton and biathlon was lower by 51 and 72% (p Vitamin A, C and B2, and beta-carotene blood serum level did not significantly differ in junior and adult athletes. Women were better supplied with vitamins C, B2, and beta-carotene: a reduced blood serum level of these micronutrients in women was detected 2-3 fold rare (p vitamin C (1.20 +/- 0.05 mg/dl) and beta-carotene (32.0 +/- 3.9 mcg/dl) in women was greater by 15 and 54% (p vitamins compared with other athletes.

    Full Text Available People with epilepsy are prone to be sedentary compared with the general population. The causes of inactivity are ignorance, prejudice, overprotection, fear and shame. There is no scientific evidence supporting a limitation of physical exercise in persons with epilepsy. The benefits of exercise in these patients are huge. Positive aspects are: physical conditioning, prevention of seizures, emotional wellbeing, social interaction, drug treatment adherence, osteoporosis prevention and better quality of life for patients and their families. Having in mind the individual characteristics, physical exercise should be prescribed and guided. Available evidence underlies the complementary therapeutic effects of physical activity with large positive results at a low cost. Sports or regular physical activity should be a standard indication for persons with epilepsy.

    2013-11-01

    Joint arthroplasty is one of the commonest surgical procedures in orthopedic surgery. In recent years there was an increase in the number of procedures, patient satisfaction and implant survival. Originally, these operations were designed for old patients in order to relieve pain and to enable ambulation. Over the past few years, these operations have become common in younger patients which desire to return to activity, including sports activities. The importance of physical activity is a well known fact. In recent years it became clear that with the proper physical activity the outcomes of the operations are better. There are several types of arthroplasty. Many factors influence the outcome of the operation apart from the post-surgery physical activity. These factors include patient factors, surgical technique and type of arthroplasty. This review summarizes the recommendations for sports activities after hip and knee arthroplasties. These activities are evaluated according to surgeons' recommendations, stress applied on the implant and long term outcomes. The recommended sports activities after joint arthroplasties are walking, swimming and cycling. Soccer, basketball and jogging are not advised. Tennis, downhill skiing and horse riding are recommended with previous experience. There are many more sports activities that patients can participate in, and it is important that the patient discuss the different options prior to the operation. Since these operations are so common, many non-orthopedic physicians encounter these patients in their practice. They should be acquainted with the recommendations for sports activities and encourage them.

    Systematic surveillance of injuries and illnesses is the foundation for developing preventive measures in sport. To analyse the injuries and illnesses that occurred during the XXII Olympic Winter Games, held in Sochi in 2014. We recorded the daily occurrence (or non-occurrence) of injuries and illnesses (1) through the reporting of all National Olympic Committee (NOC) medical teams and (2) in the polyclinic and medical venues by the Sochi 2014 medical staff. NOC and Sochi 2014 medical staff reported 391 injuries and 249 illnesses among 2780 athletes from 88 NOCs, equalling incidences of 14 injuries and 8.9 illnesses per 100 athletes over an 18-day period of time. Altogether, 12% and 8% of the athletes incurred at least one injury or illness, respectively. The percentage of athletes injured was highest in aerial skiing, snowboard slopestyle, snowboard cross, slopestyle skiing, halfpipe skiing, moguls skiing, alpine skiing, and snowboard halfpipe. Thirty-nine per cent of the injuries were expected to prevent the athlete from participating in competition or training. Women suffered 50% more illnesses than men. The rate of illness was highest in skeleton, short track, curling, cross-country skiing, figure skating, bobsleigh and aerial skiing. A total of 159 illnesses (64%) affected the respiratory system, and the most common cause of illness was infection (n=145, 58%). Overall, 12% of the athletes incurred at least one injury during the games, and 8% an illness, which is similar to prior Olympic Games. The incidence of injuries and illnesses varied substantially between sports. Published by the BMJ Publishing Group Limited.

    This study characterizes the athletes participating in the 2010 Winter Olympic Games in terms of body height, body mass and BMI. The studied sample consisted of athletes in the top 20 places of each of 14 sports disciplines (1460 cases). Data on the athletes' age, height, body mass, and sports specialization were obtained from the Olympic Games' official website and from the International Ski Federation. The sampled athletes were grouped according to the predominant type of energy metabolism during competition. The anaerobic-glycolytic disciplines, such as cross-country sprint, figure skating, short track, and speed skating (500, 1000 and 1500 m), were found to have the youngest female athletes: 25.0 yr. (SD = 4.7). In the endurance sports (aerobic and aerobic-anaerobic), the female athletes were the oldest, being respectively 28.6 yr. (SD = 4.9) and 28.1 yr. (SD = 4.5) old. In the speed disciplines (anaerobic-alactic), the female athletes were the tallest (M = 172 cm; SD = 8.3). The male athletes in the anaerobic-alactic sports were the tallest (M = 181.8 cm, SD = 6.7) and those in the anaerobic-glycolytic sports were the shortest (M = 179.2 cm, SD = 6.7). The large differences in body mass among the groups of athletes, which appear to be related to the predominant type of metabolism during competition, show that this parameter is partly correlated with the level of sports competence, but only in disciplines where the athletes need larger muscle mass. The largest average values of BMI were found for males and females in the anaerobic-alactic group.

    Full Text Available Sport involvement among children and adolescents has been a central field of research in sport science since years. This paper documents the participation of 11- to 15-year-olds in sport clubs and informal sport activities in Liechtenstein and examines possible gender- and age-specific differences. The analysis is based on four cross-sectional studies from 2004 to 2015 and includes the data of 1’262 children in primary (5th grade and secondary (7th and 9th grades school. According to our findings sports and exercise are considered to be one of the main leisure-time activities for all school levels (irrespective of gender. The percentage of fully sport-abstinent adolescents by 11- and 13-year-olds is about 5 %; by 15-year-olds is around 10 %. The culmination of sports club membership (with current 84.7 % appears to be at the age of 11 (5th grade. After the switch to secondary school the sports club commitment tends to decrease, while the high attendance of the informal sport activities (>85 % shows relatively stable age development. In contrast to other child and youth studies, our data indicates a levelling tendency and dissolution of classic gender differences not only in sports club commitment but also in informal sports among girls and boys.

  20. Are cold winters in Europe associated with low solar activity?

    Solar activity during the current sunspot minimum has fallen to levels unknown since the start of the 20th century. The Maunder minimum (about 1650-1700) was a prolonged episode of low solar activity which coincided with more severe winters in the United Kingdom and continental Europe. Motivated by recent relatively cold winters in the UK, we investigate the possible connection with solar activity. We identify regionally anomalous cold winters by detrending the Central England temperature (CET) record using reconstructions of the northern hemisphere mean temperature. We show that cold winter excursions from the hemispheric trend occur more commonly in the UK during low solar activity, consistent with the solar influence on the occurrence of persistent blocking events in the eastern Atlantic. We stress that this is a regional and seasonal effect relating to European winters and not a global effect. Average solar activity has declined rapidly since 1985 and cosmogenic isotopes suggest an 8% chance of a return to Maunder minimum conditions within the next 50 years (Lockwood 2010 Proc. R. Soc. A 466 303-29): the results presented here indicate that, despite hemispheric warming, the UK and Europe could experience more cold winters than during recent decades.

    Full Text Available Starting from the definition of sport, the author has presented the possibilities its application in the prevention of crime and delinquency. In that context, the author analyzes the rate of juvenile delinquency in specific countries, such as Canada, and underlines the fact that the classical criminal measures do not give adequate results. The author points out that it is, therefore, necessary to apply some other preventive measures, which embody the application of sports and physical activity. The author provides examples of good practice in the states which has achieved the best results in the development of such programs. Finally, in view of the increasing number of reported criminal offences committed by both juveniles and adults, the author highlights the need for developing such programs in the Republic of Serbia.

This study is reviewing nowadays Romania’s tourism supply (2015 – laying special emphasis on the North-West Development Region’s situation – in terms of winter sports potential (resources and material and technical base (specific infrastructure. It calls into question a highly discussed topic within the domain of interest of Tourism Geography, whose recursiveness could be justified by countinuous changes that influence the quantitative and qualitative configuration of ski areas, ski tracks and related equipment2. The existence of favourable natural support in terms of relief and climate is an indispensable prerequisite to the development of winter sports tourism within any area. From this point of view, the presence of the Carpathians is a major advantage for Romania, the more so as the proportion of the mountain sector represents 30 percent of the national area (238,391 square kilometres. By occupying different amounts of the territory belonging to 6 development regions and 19 counties, heterogeneous tourism potential values have emerged, causing unequal exploitation opportunities within the mountain area. The purpose of this paper is to provide a general framework of Romanian ski slopes, areas and corresponding facilities for assessing their current state, from regional perspective, with emphasis on North-West’s situation. On this line, the main objectives, starting from identifying and inventorising to classifying regions and ski tracks based on hierarchical categories, also deal with ranking slopes according to surface, length, width, elevation of departure point, difference in elevation, difficulty ratings, capacities of slopes and cable transportation means. In order to achieve these goals, quantitative research methods and techniques mostly refered to observation, analysis, synthesis and

    The continuity hypothesis in its general form states that dreams reflect waking life: concerns, thoughts, and experiences (G. W. Domhoff, 1996; M. Schredl, 1999; I. Strauch & B. Meier, 1996). For example, athletes and sport students dream about sports more often than do psychology students, presumably reflecting their engagement in sport activities and sport theory (D. Erlacher & M. Schredl, 2004). In the present study, the authors tested the previously unexamined hypothesis that differences in dream content would directly reflect individuals' differing amounts of waking sport activities. As expected, the amount of time that individuals spent engaged in an activity (sports or reading) was directly related to their percentage of corresponding dreams. Also, individuals reported reading dreams less frequently than they did sport dreams, although reading was more prominent in their waking lives than were sport activities. The findings also indicated that other factors such as emotional involvement and associated worries might be of importance in explaining the relation between waking activities and dream events. Future studies using longitudinal designs would shed more light on this relation and would help derive a more precise formulation of the continuity hypothesis.

    Modern therapy options offer haemophiliacs more and more possibilities for an active participation in sports. The purpose of the present study was to investigate the attitude of these patients towards sports, their participation in school and leisure time sports activities, and differences between juveniles and adults. We investigated 44 children and adolescents (aged from 4 to 16 years) and 27 adults (aged from 18 to 72 years) with haemophilia by means of a questionnaire. 79.6% of the juvenile patients participated always or almost always in school sports, while this percentage was significantly (P Sports play an important or very important role in leisure time activities for 75% of the adolescent and 55.5% of the adult haemophiliacs (P sports. There were only slight differences between both groups, regarding their motivation to participate in sports activities. The main reasons involved social aspects and having fun. The results show that the modern therapy of haemophilia probably leads to a more positive attitude towards sports and to a wider spectrum of practised sports. This, however, may be associated with an increasing potential of health risks, which require a high level of sports medical care.

    2013-09-01

    Anaerobic capacity/anaerobically attributable power is an important parameter for athletic performance, not only for short high-intensity activities but also for breakaway efforts and end spurts during endurance events. Unlike aerobic capacity, anaerobic capacity cannot be easily quantified. The 3 most commonly used methodologies to quantify anaerobic capacity are the maximal accumulated oxygen deficit method, the critical power concept, and the gross efficiency method. This review describes these methods, evaluates if they result in similar estimates of anaerobic capacity, and highlights how anaerobic capacity is used during sporting activities. All 3 methods have their own strengths and weaknesses and result in more or less similar estimates of anaerobic capacity but cannot be used interchangeably. The method of choice depends on the research question or practical goal.

    Common concerns of patients undergoing total hip arthroplasty are whether they can continue with certain recreational and sporting activities or even commence new ones after the procedure. The present paper describes preoperative and postoperative activities, the numbers participating and the time to resume these activities. Between 1 and 2 years after total hip arthroplasty, 216 patients, who had undergone a total of 235 arthroplasties, were surveyed by postal questionnaire to ascertain how the arthroplasty had affected their recreational and sporting ability. Their preoperative and postoperative activity along with the time to resume was recorded. A general hip score and estimate of physical activity was also collected. The number of patients participating in sport increased from 188 preoperatively to 196 postoperatively. Patients stated that the surgery had a beneficial effect on their performance of sporting activities although the number of sporting events decreased. By multiplying individuals by the number of sports they participated in, there were 434 occurrences of sport preoperatively giving a mean for the group of 1.9 sports per patient. Postoperatively this had reduced to 382, giving a mean of 1.7. Five sports showed a significant change for individual patients from pre to postoperation. Those which showed an increase were exercise walking, where 38 patients (16.8%) who did not walk before surgery took up walking afterwards (P aqua aerobics, where 15 took up this activity postoperatively for the first time (P = 0.002). There were three sports which decreased significantly from pre to postoperation. They were, golf where 13 out of 39 (P = 0.005), tennis 13 out of 14 (P = 0.01) and jogging where six out of seven (P = 0.01) patients stopped participating.

    Regular exercise reduces cardiovascular and overall mortality. Participation in sports is an important determinant of cardiovascular health and fitness. Regular sports activity is associated with a smaller risk of sudden cardiac death (SCD). However, there is a small risk of sports-related SCD. Sports-related SCD accounts for approximately 5% of total SCD. SCD among athletes comprises only a fraction of all sports-related SCD. Sport-related SCD has a male predominance and an average age of affliction of 45 to 50 years. Survival is better than for other SCD. This review summarizes links between sports and SCD and discusses current knowledge and controversies. Copyright © 2017 Elsevier Inc. All rights reserved.

    Models of sport development often support the assumption that young athletes' psychosocial experiences differ as a result of seemingly minor variations in how their sport activities are designed (eg, participating in team or individual sport; sampling many sports or specialising at an early age). This review was conducted to systematically search sport literature and explore how the design of sport activities relates to psychosocial outcomes. Systematic search, followed by data extraction and synthesis. The Preferred Reporting Items for Systematic reviews and Meta-Analyses guidelines were applied and a coding sheet was used to extract article information and code for risk of bias. Academic databases and manual search of peer-reviewed journals. Search criteria determined eligibility primarily based on the sample (eg, ages 7 through 17 years) and study design (eg, measured psychosocial constructs). 35 studies were located and were classified within three categories: (1) sport types, (2) sport settings, and (3) individual patterns of sport involvement. These studies represented a wide range of scores when assessed for risk of bias and involved an array of psychosocial constructs, with the most prevalent investigations predicting outcomes such as youth development, self-esteem and depression by comparing (1) team or individual sport participants and (2) youth with varying amounts of sport involvement. As variations in sport activities impact youth sport experiences, it is vital for researchers to carefully describe and study these factors, while practitioners may use the current findings when designing youth sport programmes.

    There is a lack of detailed information about habitual physical activity levels and the sports participation of patients after total ankle arthroplasty. The proportion of sports active patients increases after total ankle arthroplasty, and the majority of patients will meet current recommendations for health-enhancing physical activity. Case series; Level of evidence, 4. The authors assessed the pre- and postoperative participation in sports and recreational activities of 101 patients at a mean of 3.7 years after total ankle arthroplasty. Activity levels were determined with use of the University of California at Los Angeles (UCLA) activity scale. The International Physical Activity Questionnaire (IPAQ) was used to quantify habitual physical activity levels and to calculate the proportion of patients meeting current guidelines for health-enhancing physical activity. The American Orthopaedic Foot and Ankle Society (AOFAS) hindfoot score was used as the clinical outcome measure. Radiographs were studied for tibial and talar radiolucencies, and any association between radiolucencies, activity levels, and sports participation was determined. Preoperatively, 62.4% of the patients were active in sports; 66.3% were active after surgery (P=.56). The patients were active in 3.0 +/- 1.8 different sports and recreational activities preoperatively and in 3.0 +/- 1.6 activities after surgery (P =1.0). The sports frequency remained unchanged, with 2.0 +/- 1.6 sessions per week before total ankle arthroplasty and 2.3 +/- 1.7 sessions per week postoperatively (P=.19). Overall, the patients were active in sports and recreation for 3.9 +/- 3.8 hours per week pre-operatively, and for 4.7 +/- 3.9 hours per week after surgery (P=.14). The most common disciplines after total ankle arthroplasty were swimming, cycling, and fitness/weight training. Sixty-five percent of the patients stated that surgery had improved their sports ability. The UCLA activity levels increased significantly from

    Traveling with sports teams requires flexibility and a wide range of knowledge, as well as problem-solving abilities. Dominating the medical types of problems in the Nordic sports are the respiratory illnesses, especially asthma and upper respiratory infections (URI). Additionally, the team physician must have an awareness of antidoping issues. This overview highlights many of the issues encountered traveling domestically as well as internationally with high-level Nordic teams. Helpful links are included to facilitate the care of all levels of athletes. Additionally, a few side issues such as altitude illness and minor trauma are mentioned.

    To evaluate the association between sports activities and allergic symptoms, especially rhinitis, among schoolchildren. This longitudinal survey of schoolchildren collected data from questionnaires regarding allergic symptoms based on the International Study of Asthma and Allergies in Childhood (ISAAC) program and sports participation that were distributed to the parents of children at all 12 public primary schools in Ohmi-Hachiman City, Shiga Prefecture, Japan. Data were collected annually from 2011 until 2014, when the children reached 10 years of age. Blood samples were obtained in 2014, and the levels of immunoglobulin (Ig)E specific to four inhalant allergens were measured. Data from 558 children were analyzed. At 10 years of age, prevalence of asthma and eczema did not differ significantly, while rhinitis was significantly higher (p = 0.009) among children who participated in sports. Prevalence of rhinitis increased as the frequency or duration of sports participation increased (p sports (p = 0.03). Among those who participated in continuous sports activities, the prevalence of rhinitis was significantly higher with prolonged eczema (p = 0.006). Sports activities did not increase sensitization to inhalant allergens. Sports activities enhance the prevalence of rhinitis in schoolchildren. Prolonged eczema, together with sports participation, further promotes the symptoms. The mechanisms of these novel findings warrant further investigation. © 2015 John Wiley & Sons A/S.

    Common concerns of patients undergoing total knee arthroplasty (TKA) are whether they can continue with certain recreational and sporting activities or even commence new ones after the procedure. The present study was designed to determine preoperative and postoperative activities, the numbers participating and the time to resume these activities. Between 1 and 2 years after TKA, patients who had undergone 144 arthroplasties, were surveyed by postal questionnaire to ascertain how the arthroplasty had affected their recreational and sporting ability. Their preoperative and postoperative activity along with the time to resume was recorded. The Oxford knee score and estimate of physical activity was also collected. Out of the 144 TKA performed, 122 participated in sport and recreational activity preoperatively and 108 participated postoperatively. Patients stated that the surgery had a beneficial effect on their performance of sporting and recreational activities although the number of sporting events decreased. By multiplying individuals by the number of activities they participated in, there were 254 occurrences of sport and recreational activities preoperatively giving a mean for the group of 1.76 sports/patient. Postoperatively this had reduced to 204, giving a mean of 1.41. Three activities showed a significant change for individual patients from pre- to postoperation. Those which showed an increase were exercise walking, where 19 patients (13.2%) who did not walk before surgery took up walking afterwards (P aqua aerobics, where five took up aqua aerobics postoperatively for the first time (P < 0.025). Golf was the only sport which had a significant fall in participation from pre- to postoperation, with 10 out of 19 golfers giving up (P < 0.025). The present study has shown that patients are adopting lower impact activities to participate in after TKA. The total number of patients performing a sport decreases postoperatively and the total amount of sport played

    For the past few years, children affected by an inherited channelopathy have been counseled to avoid (recreational) sports activities and all competitive sports so as to prevent exercise-induced arrhythmia and sudden cardiac death. An increased understanding of the pathophysiological mechanisms, better anti-arrhythmic strategies, and, in particular, more epidemiological data on exercise-induced arrhythmia in active athletes with channelopathies have changed the universal recommendation of "no sports," leading to revised, less strict, and more differentiated guidelines (published by the American Heart Association/American College of Cardiology in 2015). In this review, we outline the disease- and genotype-specific mechanisms of exercise-induced arrhythmia; give an overview of trigger-, symptom-, and genotype-dependent guidance in sports activities for children with long QT syndrome (LQTS), Brugada syndrome (BrS), catecholaminergic polymorphic ventricular tachycardia (CPVT), or short QT syndrome (SQTS); and highlight the novelties in the current guidelines compared with previous versions. While it is still recommended for patients with LQT1 and CPVT (even when asymptomatic) and all symptomatic LQTS patients (independent of genotype) to avoid any competitive and high-intensity sports, other LQTS patients successfully treated with anti-arrhythmic therapies and phenotype-negative genotype-positive patients may be allowed to perform sports at different activity levels - provided they undergo regular, sophisticated evaluations to detect any changes in arrhythmogenic risk.

    Full Text Available The transmission of positive values between parents and children is generally considered to be the hallmark of successful socialization. As this issue has been widely discussed but surprisingly little researched - especially with reference to core sport values - in this study we aimed to: 1 analyze adolescent athletes’ acceptance of the sport values their parents want to transmit to them (i.e., parental socialization values and 2 examine the relationship between parental involvement in children’s sportive activity and adolescents’ acceptance of their parents’ socialization values. One hundred and seventy-two Italian adolescents (48.3% male, 51.7% female who regularly practice team sports were asked to fill out a questionnaire which included the Youth Sport Values Questionnaire – 2 and the Parental Involvement in Sport Questionnaire. The dyadic correlations revealed that young athletes are in general willing to accept their parents’ socialization values in regards to sport. Moreover, from the relative weight analysis (a relatively new data analysis strategy, it emerged that parental involvement characterized by praise and understanding is the most important predictor of adolescents’ willingness to accept their parents’ sport values. Implications of these results and further expansion of the study are discussed.

    We here ask whether childhood sport participation is positively correlated with adult labour-market outcomes. There are many potential channels for this effect, although, as usual, identifying a causal relationship is difficult. We appeal to two widely-separated waves of Add Health data to map out the correlation between childhood sports and a number of adult labour-market outcomes. We show that different types of childhood sports are associated with both managerial responsibilities and autonomy at work when adult. We take the endogeneity of sport seriously, and appeal to a variety of techniques, including the use of data on siblings, in order to obtain estimates that are as close to unbiased as possible. Last, we compare the effect of sporting activities to that of other leisure activities.* PMID:28798886

  4. Quality of life and sports activities in patients with haemophilia.

    VON Mackensen, S

    2007-09-01

    Quality of life (QoL) is a multidimensional construct pertaining to an individual's physical, emotional, mental, social and behavioural components of well-being and functioning. QoL can be assessed using both generic and disease-specific instruments. QoL assessment in haemophilia is a relatively new area of study; the first data were published in 1990 using generic QoL questionnaires. Only recently have haemophilia-specific questionnaires been developed, first for children and then for adults. Because sports activities include not only physical and functional aspects, but also have an impact on an individual's self-esteem and social interactions, they should play an essential role in QoL assessment. Until the 1970s, persons with haemophilia were advised to avoid any kind of physical activity because of the risk of bleeds. Nowadays, however, the attitude towards sports for patients with haemophilia has changed, and the World Federation of Haemophilia has formulated recommendations concerning physical activities for patients with haemophilia. Although sports activities are recommended, their importance as an integral element in haemophilia management has not yet been widely recognized. Awareness of the importance of sports activities for this patient group has increased, and several sports projects are ongoing. For example, a twice-annual sports camp for adult patients has been held in Germany for the past 2 years; and physical improvements, QoL and subjective training effects are being measured. Another study is investigating the prevalence of sports activities in Italian children with haemophilia and their attitudes towards sports and is also assessing QoL. In Israel, a study is planned in which haemophilic children will participate in a karate training programme, and a QoL evaluation will be added to the physical assessment. In conclusion, sports activities can improve not only physical well-being, but also the emotional and social well-being of persons with

    Full Text Available Background: Regular physical activity is the crucial factor in treating lifestyle diseases. The age of adolescence is considered as the important period of person's life for creation and further maintaining healthy lifestyle habits. We assume that the level of physical activities of young people could be influenced by the possibilities to perform the preferred sporting activities. Objective: The aim of the presented study was to estimate the total amount of performed physical activity and the structure of sport preferences in West Bohemian adolescents. Further to find out the existence of relationships between preferred sport branches and composition of weekly physical activities of girls and boys. Methods: The research was conducted at five selected secondary schools of the Pilsen region, under the total participation of 382 boys and 529 girls. The level of physical activity (PA and sporting preferences was assessed by means of the IPAQ questionnaire and questionnaire of sports preferences, with the use of the internet system INDARES. For the statistical processing of the gained data, the Kruskal-Wallis ANOVA test, crosstabulation tables, and Spearman correlation analysis were used. Results: The results showed that the preference of fitness activities is associated with a higher level of PA in spare time of boys (p = .006, and with intensive PA of boys (p = .014 and girls (p = .044, compared to those, who do not prefer these activities. In addition, in case of boys, we have found statistically significant correlations (p = .022 between the preference of team sports and PA at school. 51.8% of boys and 37.7% of girls, who prefer fitness activities, comply with the recommendation of at least 3 × 20 minutes of intensive PA during one week (out of those, who do not prefer, only 30.5% of boys and 18.1% of girls.

    1989-01-01

    Cross-sectional analyses show a lower incidence of hypertension among endurance athletes compared to the general population, but not among strength athletes or high-performance swimmers. The favorable influence of increased physical activity of the endurance type on cardiovascular regulation is based on peripheral adaptation processes with a reduction in sympathetic tone and elevation of parasympathetic tone. The results are a reduction in catecholamine release, in heart rate, and in mean arterial pressure at the same exercise level. Following chronic strength training there is also a slight reduction in catecholamine levels at the same time the vagal activity decreases, so that no reduction in heart rate and pressure, and thus no economization of cardiac work results. Thus, endurance training is suited for prevention and also for the reduction of blood pressure in primary hypertension and for cardiac relief, while strength training is not. In the case of hypertension, physical activity may only be engaged in when the cardiac functional status and other organ impairments are known. The stages of cardiac adaptation and damage, particularly the differentiation between concentric and eccentric hypertrophy, are particularly important. Exercise ECG and echocardiography are therefore obligatory measures prior to initiating physical activity and for continuous monitoring of hypertension. In primary hypertension Stage I (70-80% according to WHO), in which no cardiac hypertrophy is present, endurance training may be started without drug therapy if diastolic pressure is not greater than 104 mmHg and systolic pressure up to 170 mmHg (mild hypertension). Additional drug therapy does not show any convincing advantages. Higher pressures require adjuvant drug therapy. In concentric cardiac hypertrophy (Stage II), there is clear indication for the use of hypotensive drugs. An endurance sport is to be recommended additionally after normalization of blood pressure; the regression of

    In a context of stagnation of the level of health-enhancing physical activity in Europe, this study examines the geographical stratification of sports participation and physical activity (PA) at the regional level in 28 European countries. While previous research has focused on the national approach, this study considers the regional level across 208 European regions. Individual survey data from the Eurobarometer 80.2 is combined with a regional-level approach to the 208 regions to quantify sports participation and PA at the regional level. The results show important differences and a geographical stratification of sports participation and PA among the European regions, albeit following different patterns. In particular, a north-south gap is identified in terms of PA rates and an east-west gap is detected in terms of sports participation levels. Applying the cluster technique, a taxonomy of four different European regions is developed considering both types of indicators. Finally, the existence of sports spatial spillovers among regions is verified, obtaining a positive autocorrelation among neighbouring regions for being involved in PA and sporting activities. The results may have significant implications in terms of policy measures to improve health through PA and sports participation at the regional level in Europe.

    2018-03-01

    This study investigated whether parental participation in organized and unorganized physical activity (PA) was associated with children's participation in extracurricular sport. The sample comprised 834 parents and their children (aged 6-10 years), living in central Portugal. Questionnaires assessed parental PA (organized and unorganized) and extracurricular sport participation in children (number of sports and frequency of participation). Multinomial logistic regression was applied to assess associations between parental and child physical behaviors. Having both parents active was significantly associated with frequent participation in more sports both in girls and boys but a strong relation according to gender was found. The odds of boys practicing more than one sport and more times per week were higher if they had an active father. Girls with physically active mothers, particularly with mothers practicing organized PA in a regular way, were engaged in more sports and practiced sport more times per week. The type of PA practiced by the parents was not related to boys' participation in sport. Future interventions should be family-based and focus on the promotion of higher levels of parental PA, including organized, in order to improve their children's active behaviors.

    Background Sports-associated sudden cardiac arrests (SCAs) occur mostly during middle age. We sought to determine burden, characteristics, and outcomes of SCA during sports among middle aged residents of a large US community. Methods and Results SCA cases aged 35–65 years were identified in a large, prospective, population-based study (2002–2013), with systematic and comprehensive assessment of their lifetime medical history. Of the 1,247 SCA cases, 63 (5%) occurred during sports activities at a mean age of 51.1±8.8 years, yielding an incidence of 21.7 (95%CI 8.1–35.4) per million per year. The incidence varied significantly based on sex, with a higher incidence among men (RR 18.68 95%CI 2.50–139.56) for sports SCA, as compared to all other SCA (RR 2.58, 95%CI 2.12–3.13). Sports SCA was also more likely to be a witnessed event (87 vs. 53%, Psports-associated SCA (23.2 vs. 13.6%, P=0.04). Sports SCA cases presented with known pre-existing cardiac disease in 16%, ≥1 cardiovascular risk factor in 56%, and overall, 36% of cases had typical cardiovascular symptoms during the week preceding SCA. Conclusions Sports-associated SCA in middle age represents a relatively small proportion of the overall SCA burden, reinforcing the idea of the high benefit-low risk nature of sports activity. Especially in light of current population aging trends, our findings emphasize that targeted education could maximize both safety and acceptance of sports activity in the older athlete.

    Increased sport facility proximity is associated with higher likelihood of meeting physical activity (PA) recommendations in western studies, but it is uncertain whether the findings can be generalized to the Chinese population. From September 2012 to December 2012, 3926 participants drawn from China using a multi-stage sampling strategy were invited to participate in the Study of Community Sports in China. Participants' demographics, commuting time to the nearest sport facility and PA levels were assessed. Among 3926 participants included (51.2% female) in the final analysis, 878 (22.4%) of them met the PA recommendation. Participants who spent ≥30 minutes in commuting time had 80% odds [odds ratio (OR): 0.80 (95% CI: 0.65-0.98)] of meeting the PA recommendation compared to those who spent less than 10 minutes. For every 10-minute increment in commuting time, the odds reduced by 6% [OR = 0.94 (0.88-0.99)]. The observed associations were not appreciably modified by age, gender or education level. In this cross-sectional community-based study, we found that residents in China were less likely to meet the PA recommendation if they needed more commuting time to the nearest sport facility. Increasing sport facility proximity may be effective in improving the PA levels in the Chinese population.

METHODS: Cross-sectional study with 120 schoolchildren (mean: 11.7±0.7 years old, with no regular use of medicines. Sports practice and physical education classes were assessed through face-to-face interview, while habitual physical activity was assessed by pedometers. Bodyweight, height and height-cephalic trunk were used to estimate maturation. The following variables were measured: body fatness, blood pressure, resting heart rate, blood flow velocity, intima-media thickness (carotid and femoral and heart rate variability (mean between consecutive heartbeats and statistical index in the time domain that show the autonomic parasympathetic nervous system activity root-mean by the square of differences between adjacent normal R-R intervals in a time interval. Statistical treatment used Spearman correlation adjusted by sex, ethnicity, age, body fatness and maturation. RESULTS: Independently of potential confounders, sports practice was positively related to autonomic parasympathetic nervous system activity (β=0.039 [0.01; 0.76]. On the other hand, the relationship between sport practice and mean between consecutive heartbeats (β=0,031 [-0.01; 0.07] was significantly mediated by biological maturation.

    To analyze the relationship among sports practice, physical education class, habitual physical activity and cardiovascular risk in adolescents. Cross-sectional study with 120 schoolchildren (mean: 11.7±0.7 years old), with no regular use of medicines. Sports practice and physical education classes were assessed through face-to-face interview, while habitual physical activity was assessed by pedometers. Body weight, height and height-cephalic trunk were used to estimate maturation. The following variables were measured: body fatness, blood pressure, resting heart rate, blood flow velocity, intima-media thickness (carotid and femoral) and heart rate variability (mean between consecutive heartbeats and statistical index in the time domain that show the autonomic parasympathetic nervous system activity root-mean by the square of differences between adjacent normal R-R intervals in a time interval. Statistical treatment used Spearman correlation adjusted by sex, ethnicity, age, body fatness and maturation. Independently of potential confounders, sports practice was positively related to autonomic parasympathetic nervous system activity (β=0.039 [0.01; 0.76]). On the other hand, the relationship between sport practice and mean between consecutive heartbeats (β=0,031 [-0.01; 0.07]) was significantly mediated by biological maturation. Sport practice was related to higher heart rate variability at rest. Copyright © 2015 Associação de Pediatria de São Paulo. Publicado por Elsevier Editora Ltda. All rights reserved.

    The increase in quality and life expectancy, often leads to many patients asking the glaucoma specialist whether some sports, activities or hobbies would affect their illness. The aim of this article is to establish guidelines for patients, based on the scientific evidence of published papers. Review of all published articles on glaucoma and sports or other activities. The papers were classified according to the level of scientific evidence based on the Oxford Centre for Evidence-Based Medicine classification. Aerobic sports are beneficial for the patient. Yoga indoor sports or relaxation techniques should be avoided if Valsalva manoeuvres are performed or the head is placed very low. Also, the patients must avoid sudden changes in height. Intense heat does not seem to lead to progression of glaucoma, but intense cold can affect patients with vascular dysregulation. Activities using the near vision slightly reduce the intraocular pressure. The use of wind instruments may raise intraocular pressure, depending on the technique used. Certain sports and activities may have an influence on the onset or progression of glaucoma. Glaucoma specialists should have adequate information about the scientific evidence in the publications, in order to properly advise the patients. Copyright © 2017 Sociedad Española de Oftalmología.

    The aim of this research was to compare the levels of perceived health literacy among adolescents who do or do not participate in sports club activities. Organized sport club activities reach a high proportion of adolescents, and have the potential to contribute to the development of their health literacy. The cross-sectional data on health literacy among school children in Finland (aged 13 and 15, n=3852) were measured, as a part of the Health Behaviour in School-Aged Children (HBSC) study, using the Health Literacy for School-aged Children (HLSAC) instrument. Sports club participation and its association with health literacy were examined in relation to age, gender, family affluence, school achievement, and physical activity. The statistical analyses included cross-tabulation and the multilevel mixed-effects logistic regression analyses. Perceived health literacy was higher among adolescents who participated in sports club activities. This conclusion was valid for boys and girls, for both age groups, among those who were physically active 6-7 days a week, had at least moderate school achievement, and those who belonged to the middle or high affluence families. From the health literacy perspective, participation in sports club activities was especially beneficial for those having low or moderate school achievement level. The sports club setting may work towards equalizing health literacy differences related to school achievement. However, the clubs should ensure that access is available to as many adolescents as possible; by this means they may spread beneficial influences, supporting the development of health literacy among broader population groups.

    Background Sports injury and illness surveillance is the first step in injury and illness prevention, and is important for the protection of both athlete health and performance in major competitions. Aim To identify the prevalence, severity nature and causes of athlete injuries and illnesses in the Great Britain Olympic Team (TeamGB) during the Sochi 2014 Winter Olympic Games. Methods The observational prospective cohort study followed the Great Britain Injury/Illness Performance Project surveillance methodology and obtained information on injuries and illnesses that occurred during the Games between 30 January and 23 February 2014 in TeamGB athletes (n=56). Results Among the 56 TeamGB athletes, there were 27 injuries and 11 illnesses during the Olympic Games period. This equated to 39% sustaining at least one injury and 18% at least one illness, with an incidence of 48.2 injuries and 19.6 illnesses per 100 athletes, respectively. Of all injuries and illnesses, 9% and 7%, respectively, resulted in time loss. The risk of sustaining an injury was highest for freestyle skiing, skeleton and snowboarding; and lowest for curling, biathlon and Alpine skiing (with no reported injuries); with the lower limb being the most commonly injured location. Respiratory system illnesses were most frequently reported overall, and older female athletes were the ones most affected by illness. Conclusions The risk of injury was double the risk of illness for TeamGB athletes. Overall, the rate of time-loss issues was low. Methodological considerations are important when interpreting data, and prevention strategies should focus on those issues causing the greatest risk, in terms of prevalence and severity, to athlete health and performance.

    The purpose of this study was to evaluate the validity and interrater reliability of the Observational System for Recording Activity in Children: Youth Sports (OSRAC:YS). Children (N = 29) participating in a parks and recreation soccer program were observed during regularly scheduled practices. Physical activity (PA) intensity and contextual factors were recorded by momentary time-sampling procedures (10-second observe, 20-second record). Two observers simultaneously observed and recorded children's PA intensity, practice context, social context, coach behavior, and coach proximity. Interrater reliability was based on agreement (Kappa) between the observer's coding for each category, and the Intraclass Correlation Coefficient (ICC) for percent of time spent in MVPA. Validity was assessed by calculating the correlation between OSRAC:YS estimated and objectively measured MVPA. Kappa statistics for each category demonstrated substantial to almost perfect interobserver agreement (Kappa = 0.67-0.93). The ICC for percent time in MVPA was 0.76 (95% C.I. = 0.49-0.90). A significant correlation (r = .73) was observed for MVPA recorded by observation and MVPA measured via accelerometry. The results indicate the OSRAC:YS is a reliable and valid tool for measuring children's PA and contextual factors during a youth soccer practice.

    The NASA Short-term Prediction Research and Transition (SPoRT) program is a partner with the GOES-R Proving Ground (PG) helping prepare forecasters understand the unique products to come from the GOES-R instrument suite. SPoRT is working collaboratively with other members of the GOES-R PG team and Algorithm Working Group (AWG) scientists to develop and disseminate a suite of proxy products that address specific forecast problems for the WFOs, Regional and National Support Centers, and other NOAA users. These products draw on SPoRT s expertise with the transition and evaluation of products into operations from the MODIS instrument and the North Alabama Lightning Mapping Array (NALMA). The MODIS instrument serves as an excellent proxy for the Advanced Baseline Imager (ABI) that will be aboard GOES-R. SPoRT has transitioned and evaluated several multi-channel MODIS products. The true and false color products are being used in natural hazard detection by several SPoRT partners to provide better observation of land features, such as fires, smoke plumes, and snow cover. Additionally, many of SPoRT s partners are coastal offices and already benefit from the MODIS sea surface temperature composite. This, along with other surface feature observations will be developed into ABI proxy products for diagnostic use in the forecast process as well as assimilation into forecast models. In addition to the MODIS instrument, the NALMA has proven very valuable to WFOs with access to these total lightning data. These data provide situational awareness and enhanced warning decision making to improve lead times for severe thunderstorm and tornado warnings. One effort by SPoRT scientists includes a lightning threat product to create short-term model forecasts of lightning activity. Additionally, SPoRT is working with the AWG to create GLM proxy data from several of the ground based total lightning networks, such as the NALMA. The evaluation will focus on the vastly improved spatial

    Full Text Available The main aim of this study was to examine the differences in motivation to participate in sport activities among sports students from three different countries. On a sample of 390 sports students from Slovenia, Croatia and Germany we studied what motivates an interest in being sports active. The sample was stratified across the choice to attend table tennis lessons at all three institutions and all students have completed the Participation Motivation Questionnaire (PMQ. The results revealed that the latent structure of the types of sports students' motives consisted of six factors (sport action with friend, popularity, fitness & health, social status, sports events, relaxation through sports. We also found significant sex differences in motivation to participate in sport activities for all sports students from the three different countries. We did not find relevant age-based differences among the students, and this is the only initial hypothesis that we can reject.

    An adequate level of physical activity has a substantial effect on both mental and physical human health. Physical activity is largely dependent on the function of the musculoskeletal and articular system. One of the most frequent diseases of this system is degenerative joint disease. Due to the changing and more demanding lifestyles and patients' willingness to be involved in sports activity, the expectations of hip joint arthroplasty are becoming increasingly high. Alleviating pain ceases to be the only reason for which patients choose surgical interventions, while the expectations often include involvement in various sports. Only few studies contain recommendations concerning the frequency, type and intensity of sports activity which are acceptable after hip joint arthroplasty. The aim of the study was to evaluate function and physical activity of people following cementless short-stem hip joint arthroplasty in the observation of at least five years. The study group comprised 106 patients who underwent total hip arthroplasty due to degenerative joint diseases, chosen according to inclusion criteria. Patients underwent routine physical examinations following the Harris Hip Score protocol, responded to the UCLA scale and questionnaires concerning pre-surgical and current physical activity. Our results demonstrated that hip joint arthroplasty in people suffering from degenerative joint diseases has a beneficial effect on their level of functioning and physical activity. Although physical activity and the level of functioning obviously reduced as a person aged, the level of physical activity continued to be very high in both groups, with function of the hip joint evaluated as very good.

    2008-06-01

    The Out of School Hours Sports Program (OSHSP) aimed to provide structured sporting experiences and community links to local clubs for children in Out of School Hours Care (OSHC). The OSHSP involved 17 State Sporting Associations (SSAs), 71 OSHC Services and local club representatives. This study explored children's participation in sport in and outside the OSHSP and parental intention for participation in sport in and outside the OSHSP. Surveys were received from 211 children (76 girls and 125 boys; mean age=7.9 years, S.D.=1.7) and their parents/guardians (37.9% response rate). OSHC is characterised by freedom of choice of participation in activities by children. The OSHSP was used to provide an opportunity to choose to participate in a sport while attending OSHC. At the OSHC Services surveyed, between 7.1 and 100% of the children attending OSHC chose to participate in the OSHSP. Of those children who chose to participate, 85% were participating in a sport, usually a different sport to the one offered in the OSHSP. This participation was largely club-based (49.8%), most often once a week for training and competition (55.2%). Parental intentions for children's participation in the OSHSP sports varied with respect to the number of years attending the OSHSP, where children played and trained in their main sport, and how many times a week a child played and trained in their main sport. Older children tended to play and train for sport more times per week and had been attending the OSHC for more years than younger children.

    Coracoid fractures sustained during sporting activities are rare. Previous reports are limited to individual case reports, small case series, and retrospective analyses. To systematically review the literature and identify coracoid fractures sustained during sporting activities to determine fracture prevalence, sporting activities/mechanisms, management, and time to return to sport. Systematic review. A systematic review was conducted investigating all studies in the literature published between January 1970 and April 2017 that reported on athletes sustaining coracoid fractures during sporting activity. The systematic review followed the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines and used PubMed, Biosis Previews, SPORTDiscus, PEDro, and EMBASE databases. Inclusion criteria were studies detailing (1) coracoid fractures with reported sporting activity causing injury, (2) fracture management (operative vs nonoperative), and (3) patient outcome. Exclusion criteria were (1) studies concerning fractures secondary to nonsporting activities (mechanical falls, motor vehicle accidents) and (2) studies not reporting fracture management or patient outcomes. Sporting activities, the presence or absence of associated acromioclavicular (AC) joint injury, fracture management, patient outcomes, and time to return to sport were analyzed. A total of 21 cases of coracoid fractures sustained during sporting activity were identified; acute trauma was responsible for 71% (n = 15/21) of fractures, and the remaining injuries were secondary to fatigue fractures. Concurrent AC joint injury was present in 60% (n = 9/15) of athletes sustaining acute trauma and in no athlete with fatigue fractures. Fractures were treated conservatively in 76% (n = 16/21) of patients, with only 19% (n = 3/16) of athletes reporting complications. Mean overall time to return to sport was 2.8 ± 2.0 months; no significant differences in return to sport were noted in

    Full Text Available This paper summarizes the current knowledge on winter active Carabidae in Central and Northern Europe. In total 73 winter active species are listed, based on literature and own observations. Ground beetles are among the three most numerous Coleoptera families active during the autumn to spring period. The winter community of Carabidae is composed both of larvae (mainly autumn breeding species and adults, as well as of epigeic species and those inhabiting tree trunks. Supranivean fauna is characterized by lower species diversity than the subnivean fauna. The activity of ground beetles decreases in late autumn, is lowest during mid-winter and increases in early spring. Carabidae are noted as an important food source in the diet of insectivorous mammals. They are also predators, hunting small winter active invertebrates.

    Full Text Available Foraging bumblebees are normally associated with spring and summer in northern Europe. However, there have been sightings of the bumblebee Bombus terrestris during the warmer winters in recent years in southern England. But what floral resources are they relying upon during winter and how much winter forage can they collect?To test if urban areas in the UK provide a rich foraging niche for bees we set up colonies of B. terrestris in the field during two late winter periods (2005/6 & 2006/7 in London, UK, and measured their foraging performance. Fully automatic radio-frequency identification (RFID technology was used in 2006/7 to enable us to record the complete foraging activity of individually tagged bees. The number of bumblebees present during winter (October 2007 to March 2008 and the main plants they visited were also recorded during transect walks. Queens and workers were observed throughout the winter, suggesting a second generation of bee colonies active during the winter months. Mass flowering shrubs such as Mahonia spp. were identified as important food resources. The foraging experiments showed that bees active during the winter can attain nectar and pollen foraging rates that match, and even surpass, those recorded during summer.B. terrestris in the UK are now able to utilise a rich winter foraging resource in urban parks and gardens that might at present still be under-exploited, opening up the possibility of further changes in pollinator phenology.

    Sports activity after surgical AC joint stabilisation has not been comprehensively evaluated to date. The aim of this study was to determine rate, level and time to return to sports after AC joint stabilisation and to identify the influence of overhead sports on post-operative sports activity. In this retrospective case series, a total of 68 patients with a high-grade AC joint dislocation (Rockwood type V) were stabilised using a single TightRope technique. Fifty-five patients (80.9 %) with median age of 42.0 (range, 18-65) years completed questionnaires regarding sports activity before and after surgery. Clinical outcome and complications were also evaluated. Forty-three patients participated in sports regularly before injury. Their sports activity was rated according to Allain, and non-overhead and overhead sports were differentiated. At median follow-up of 24 (18-45) months, 41 of 43 patients (95.3 %) had returned to sports. 63 % returned to the same sports activity as before injury. 16.3 % needed to adapt the type of sports to reduce demanding activities. 11.6 % reduced the frequency and 32.5 % the intensity of sports. The median time to return to sports was 9.5 (3-18) months. Overhead athletes (Allain Type III and IV) had to reduce their sports activity significantly more often (11.8 vs. 53.8 %; p = 0.011) and needed more time to return to sports (9.5 vs. 4.5 months; p = 0.009). After stabilisation of AC joint dislocation, the majority of patients returned to sports after a substantial period of time. Overhead athletes, in particular, required more time and had to considerably reduce their sports activity. The findings impact therapeutic decision-making after AC joint injury and help with the prognosis and assessment of rehabilitation progress. IV.

The study design employs cross-sectional multilevel and multimethod research with aspirations to a prospective cohort study in the next phase. The setting-based variables at sports clubs and coaching levels, and health behaviour variables at the individual level, are investigated using surveys; and total levels of physical activity are assessed using objective accelerometer measurements. Health status variables will be measured by preparticipation screening. The health promotion activity of sports clubs (n=154) is evaluated by club officials (n=313) and coaches (n=281). Coaches and young athletes aged 14-16 (n=759) years evaluate the coaches' health promotion activity. The survey of the adolescents' health behaviours consist of two data sets-the first is on their health behaviours and the second is on musculoskeletal complaints and injuries. Data are collected via sports clubs (759 participants) and schools 1650 (665 participants and 983 non-participants). 591 (418 athletes and 173 non-athletes) youth, have already participated in preparticipation screening. Screening consists of detailed personal medical history, electrocardiography, flow-volume spirometry, basic laboratory analyses and health status screening, including posture, muscle balance, and static and dynamic postural control tests, conducted by sports and exercise medicine specialists. The HPSC study is carried out conforming with the declaration of Helsinki. Ethical approval was received from the Ethics Committee of Health Care District of Central Finland.

    Güllich, Arne

    2017-12-01

    The study examined developmental participation patterns of international top athletes. Pairs of 83 international medallists (including 38 Olympic/World Champions) and 83 non-medallists were matched by sport, age and gender. A questionnaire recorded their volume of organised (coach-led) practice/training in their respective main sport and in other sports through childhood, adolescence and adulthood, and also involvement in non-organised (peer-led) sport activity. Analyses revealed that the medallists started practice/training in their main sport at an older age than non-medallists and accumulated slightly, but significantly less main-sport practice/training through childhood/adolescence. But they participated in more practice/training in other sports, particularly before entering their main sport. The medallists also maintained engagement in other sports over more years and specialised later than the non-medallists. Other sports engaged in were mostly unrelated to an athlete's main sport. The results were robust across different types of sports. The observations are reflected against tenets of the "deliberate practice" and "Developmental Model of Sport Participation" frameworks. Early diversified practice and learning experiences are discussed relative to the expansion of youngsters' potential for future long-term learning. In elite athletes, interaction of sport-specific practice/training with early other-sports participation mostly facilitates long-term attainment of international senior medals.

    Full Text Available An adequate level of physical activity has a substantial effect on both mental and physical human health. Physical activity is largely dependent on the function of the musculoskeletal and articular system. One of the most frequent diseases of this system is degenerative joint disease. Due to the changing and more demanding lifestyles and patients’ willingness to be involved in sports activity, the expectations of hip joint arthroplasty are becoming increasingly high. Alleviating pain ceases to be the only reason for which patients choose surgical interventions, while the expectations often include involvement in various sports. Only few studies contain recommendations concerning the frequency, type and intensity of sports activity which are acceptable after hip joint arthroplasty. The aim of the study was to evaluate function and physical activity of people following cementless short-stem hip joint arthroplasty in the observation of at least five years. The study group comprised 106 patients who underwent total hip arthroplasty due to degenerative joint diseases, chosen according to inclusion criteria. Patients underwent routine physical examinations following the Harris Hip Score protocol, responded to the UCLA scale and questionnaires concerning pre-surgical and current physical activity. Our results demonstrated that hip joint arthroplasty in people suffering from degenerative joint diseases has a beneficial effect on their level of functioning and physical activity. Although physical activity and the level of functioning obviously reduced as a person aged, the level of physical activity continued to be very high in both groups, with function of the hip joint evaluated as very good.

  13. Latitudinal trends in human primary activities: characterizing the winter day as a synchronizer.

    This work analyzes time use surveys from 19 countries (17 European and 2 American) in the middle latitude (38-61 degree) accounting for 45% of world population in this range. Time marks for primary activities are contrasted against light/dark conditions. The analysis reveals winter sunrise synchronizes labor start time below 54 degree, occurring within winter civil twilight. Winter sunset is a source of synchronization for labor end times. Winter terminator punctuate meal times in Europe: dinner occurs 3 h after winter sunset time within 1 h; 40% narrower than variability of dinner local times. The sleep-wake cycle of laborers is shown to be related to winter sunrise whereas standard population's appears to be irrespective of latitude. The significance of the winter terminator depends on two competing factors average labor time (~7 h30 m) and the shortest photoperiod. Winter terminator gains significance when both roughly matches. That is within a latitude range from 38 degree to 54 degree. The significance of winter terminator as a source of synchronization is also related to contemporary year round time schedules: the shortest photoperiod represents the worst case scenario the society faces.

    Full Text Available The main activities of the leading sports leagues were described. Sources of revenue and expenditure were identified. The economic performance of professional sports leagues of the United States of America was compared. In the course of the study of economic efficiency of the leading American sports leagues are defined payroll (expense commands on the salaries of players for each team, the total payroll in the League and the average payroll, respectively, for each of the American League. The largest estimates on wages, both in the League and in teams - in the National football League, the largest player's contract - in the Highest League baseball, the minimum wage in the National hockey League; the highest average wages, a greater percentage of athletes with a salary of more than 1 million. $ (82,85 % in the National basketball Association were showed. This difference in the maximum income of the League and of average wages is due to several factors: the number of players in the team, the number of games in a season, and expenses on carrying out of competition and training activities.

    Full Text Available Torrance tests of creative thinking have been widely used to measure the impact of different items such as creativity on different groups of children. In this study, we perform an empirical study to measure the effects of endurance, power-based and flexibility on a group of children's creativity, originality and flexibility. The study chooses a sample of 341 from 2978 preschool children and distributes a questionnaire among them where 153 were female and 188 of them were male. Cronbach alpha for creativity, originality and fluency were calculated as 0.814, 0.822 and 0.788, respectively. The results of our study indicate that there are some positive and meaningful relationship among three components of creativity, originality and fluency before and after accomplishing test. The impact of test was measured for three types of sport activities including endurance, power-based and flexibility tests. After applying 32 sessions of sporting games, flexibility games represent a mean value of 32.40, which is higher than the other two tests and it maintains meaningful value compared with two other sporting tests of endurance and power base tests.

    Full Text Available The modern world imposes strict conditions on people in various types of activities. A huge amount of processed information, tight timelines and other factors may cause people’s inability to cope with their tasks. Thus, there is a popular habit to put off the work without thinking about the consequences. This trait called procrastination is inherent to a million people all over the world. The problem of procrastination is just beginning to develop in Russia. Nowadays lots of foreign research and foreign questionnaires are being translated and approbated. The aim of this research is to identify the level of athletes’ procrastination, and define the differences of procrastination patterns in individual and team sports athletes. Also we want to study the relationship between procrastination and athletes’ personal characteristics such as extroversion, neuroticism, control over the actions, motivation to success, anxiety, time perspective and decision-making style (coping, and also indicators of state anxiety using a sample of individual athletes (boxing, unarmed self-defence, judo, karate, kickboxing, wrestling, taekwondo and teams (hockey, football, volleyball. Correlation analysis shows structural differences of procrastination manifestations in different types of sport. Regression analysis shows that in athletes of individual sports (model: p = 0,002, adjusted R2 = 0,368 there is only one significant predictor of procrastination - the negative past (p = 0,007, β = 0,495.

    This overview reports published data about the interaction between physical activity and sport during and after cancer on one hand and improvement in psychological parameters, survival and biological mechanisms underlying this effect on the other hand. Practising physical activity and sport during cancer modifies parameters assessing fatigue and quality of life and reduces symptoms of depression. An association also exists between the practise of physical activity and sport and overall and cancer-specific survivals, especially after breast cancer, colon cancer and prostate cancer. These benefits seem to be mediated by a modification of circulating levels of estrogens, insulin, IGF-1 and by a decrease in insulin-resistance, by alterations in the secretion of adipokines, and by a reduction in chronic inflammation through decreased levels of cytokines. There exist some obstacles to the practise of physical activity. These obstacles are mainly related to a fear of pain induced by physical activity and to overweight. These programmes of physical activity and sport cannot be offered to all patients since there are several contra-indications, with some being present since the initial visit and others appearing during cancer management either due to disease progression or related to iatrogenic effects. Whereas benefits from physical activity and sport among cancer patients seem obvious, there are still several pending clinical and biological issues. Copyright © 2014 Elsevier Ireland Ltd.

    Full Text Available The low level of physical fitness of intellectually disabled individuals is most often the result of a sedentary lifestyle and the lack of the possibility for these individuals to take part in various forms of physical activity, and as a consequence these individuals are often unable to take part in any form of planned physical activities, are unable to adequately perform everyday activities and have limited abilities for performing workrelated duties. Regular physical activity can have a preventive effect, can reduce health risks and prevent the onset of various illnesses, as well as to promote an active lifestyle and increase physical and work capacities among the members of this particular population. Sport can play an important role in the life of individuals with intellectual disability as it represents a good basis for the development of physical and cognitive abilities. Team sports, which include interaction among a large number of people, a decision-making processes in a variety of situations and the understanding of the game itself in its constituent parts can be used as an effective and practical treatment of individuals with intellectual disability.

    Full Text Available Advertising is an attractive promotional tool for marketers who can use it to strengthen communication with consumers and persuade them to purchasing certain product or service (Bjelica et al., 2014; Muratović et al., 2014. Hence, there is nececity to analyse their general attitudes among various questions, while this research was aimed at gaining relevant knowledge about the attitudes of Serbian consumers toward advertising through sport among the question how often they participate in sports activities. Methods: The sample included 127 respondents, divided into six subsample groups: consumers who do not participate in sport activities at all, then consumers who participate in sport activities less than ones a month, next 1–4 a month, 5–10 a month, 11–20 a month, as well as consumers participate in sport activities more than 20 times a months. The sample of variables contained the system of three general attitudes which were modeled by seven-point Likert scale. The results of the measuring were analyzed by multivariate analysis (MANOVA and univariate analysis (ANOVA and Post Hoc test. Results: Based on the statistical analyses it was found that significant differences didn’t occur at multivariate level, as well as between all three variables at a significance level of p=.05. Hence, it is interesting to highlight that it was found there are no significant differences showed up between the consumers who participate in various sports activities. Discussion: These results are so important for the marketers, mostly due to the reason they can merge all the potential consumers who participate in various sports activities into one homogenious group. This wasn’t the case in previous investigations (Popović et al., 2011 and this observation presents relevant information.

    In the Wadden Sea common starfish is an important predator of mussel beds which in turn are relevant ecological and economic resource. To improve the management of mussel seedbeds, knowledge is required on over winter predation, a factor affecting mussel survival. The aim of this study was to assess the importance of A. rubens feeding activity during winter and how it relates with changes in temperature. Feeding activity of starfish was monitored during a full winter. The potential impact of temperature change on starfish-mussel seed interactions during winter was analysed. The factor shading was included, as changes in light intensity appear to be a primary governing factor for the timing of feeding activity. The results showed that temperature limits feeding rate and feeding activity of starfish during winter. However, starfish feeding rate exhibited very high sensitivity to temperature changes. Light intensity affected both feeding rate and feeding activity. It is concluded that starfish may not be an important factor destabilising seedbeds during a mean winter, but its importance may grow along with the increasing temperature due to climate change.

  7. What do athletes drink during competitive sporting activities?

    Garth, Alison K; Burke, Louise M

    2013-07-01

    Although expert groups have developed guidelines for fluid intake during sports, there is debate about their real-world application. We reviewed the literature on self-selected hydration strategies during sporting competitions to determine what is apparently practical and valued by athletes. We found few studies of drinking practices involving elite or highly competitive athletes, even in popular sports. The available literature revealed wide variability in fluid intake and sweat losses across and within different events with varied strategies to allow fluid intake. Typical drinking practices appear to limit body mass (BM) losses to ~2 % in non-elite competitors. There are events, however, in which mean losses are greater, particularly among elite competitors and in hot weather, and evidence that individual participants fail to meet current guidelines by gaining BM or losing >2 % BM over the competition activity. Substantial (>5 %) BM loss is noted in the few studies of elite competitors in endurance and ultra-endurance events; while this may be consistent with winning outcomes, such observations cannot judge whether performance was optimal for that individual. A complex array of factors influence opportunities to drink during continuous competitive activities, many of which are outside the athlete's control: these include event rules and tactics, regulated availability of fluid, need to maintain optimal technique or speed, and gastrointestinal comfort. Therefore, it is questionable, particularly for top competitors, whether drinking can be truly ad libitum (defined as "whenever and in whatever volumes chosen by the athlete"). While there are variable relationships between fluid intake, fluid balance across races, and finishing times, in many situations it appears that top athletes take calculated risks in emphasizing the costs of drinking against the benefits. However, some non-elite competitors may need to be mindful of the disadvantages of drinking beyond

    Several important research questions have been addressed: (1) What are the cross-sectional associations between sports club participation, objectively measured physical activity, and adiposity? (2) Do measures of physical activity and adiposity predict subsequent sports club participation? (3) Does sports club participation predict subsequent measures of physical activity and adiposity? and (4) Do changes in sports club participation predict changes in objective measures of physical activity and adiposity? Longitudinal and cross-sectional. Data from the Gateshead Millennium Study birth cohort (n=609 at age 7 years) were analysed for associations between adiposity, sports club participation and accelerometer-measured physical activity from ages 7y to 9y to 12y. Seventy-two per cent of 9 year olds and 63% of 12 year olds took part in a sports club. Sports club participation was significantly associated with overall accelerometer-measured physical activity at 12y (coefficient=0.0.09; 95% CI: 0.01-0.16) but not 9y. An inverse relationship between fat mass (estimated from bioelectric impedance) and sport club participation, and between fat mass and accelerometer-measured physical activity was observed at 12y, but not 9y. Sports club participation at 9y was highly predictive of participation at 12y. Sports club participation was significantly associated with socioeconomic status; fewer children from poorer areas took part. Sports club participation in adolescence may be associated with decreased levels of adiposity. Furthermore, the potential benefits of sports club participation for adiposity are likely generated from continuous participation in sports, rather than any long-term protective effects.

    As major actors in sports activities, sports coaches can play a significant role in health education and contribute to the psychological well-being of young people. However, not all participants in sports activities experience sports positively, which reduces the potential benefits for health. The present study investigates if coaches' efforts to promote health increase young athletes' enjoyment, self-esteem and perceived health in daily life and decrease sport dropout. To control for the variability between teams and between clubs, multilevel modeling was applied. A sample of 342 young football players completed questionnaires assessing their perceptions of coaches' Health Promotion (HP) activities, enjoyment of sports, dropout intentions, self-esteem and perceived health in daily life. HP general score was positively related to enjoyment and perceived health as well as negatively dropout intentions. Players perceiving their coaches as promoting fair and play (Respect for oneself and others) scored higher on their perceptions of enjoyment in sport, self-esteem and self-reported health, and lower on dropout intentions. Moreover, players recognizing their coaches as encouraging their healthy lifestyle also reported higher perceptions of sport enjoyment, whereas player's perceived coaches' activities on substance use were associated with lower participants' enjoyment. These results support the importance of developing HP in sports clubs. Especially, promoting respect of oneself and others seems to be the more beneficial to sport participants.

    To assess the efficacy of critical metabolic power derived from variable-speed movement for classifying intensity in team sport activity. Elite male hockey players (n = 12) completed a series of time trials (100 yd, 400 yd, 1500 yd) and a 3-min all-out test to derive both critical speed (CS) and critical power (CP). Heart rate (HR), blood lactate (BLa) and rating of perceived exertion (RPE) were measured during each protocol. Participants (n = 10) then played 2 competitive hockey matches. Time spent >85% of HRmax was compared to time spent above CS (from the time trials) and CP (from the 3-min test). Between protocols, there was a moderate and non-significant association for CS (r = 0.359, P = 0.252), and a very large association for CP (r = 0.754, P = 0.005); the association was very large for peak HR (r = 0.866, P 85% HRmax and time spent above both CS (r = 0.719, P < 0.001) and CP (r = 0.867, P < 0.001). This relationship was stronger for CP compared to CS (Z = 3.29, P = 0.0007). Speed is not an appropriate parameter for the classification of team-sport activity comprising continual changes in speed and direction, however, critical metabolic power derived from variable-speed activity appears useful for this purpose.

    Full Text Available BACKGROUND: An effort to promote participation in any type of PA is more effective when it is aimed at needs, interests and preferences of particular target group. Current evidence emphasizes the insufficiency of PA in all age groups. OBJECTIVE: The purpose of the study was to analyze and describe the structure of sport activity preferences of high school students and to contribute to prospective improvement of sports and physical activity programs. METHODS: Two standardized questionnaires were used – 1. sport preferences questionnaire, 2. international physical activity questionnaire (IPAQ. The research sample (N = 333 consisted of high school students from the Czech Republic. RESULTS: Our results confirm that the differences between girls and boys are not as great as they were few decades ago. There is a visible dynamic in the development of sport preferences structure. Despite this fact there is a spectrum of sports that are constantly preferred – soccer, volleyball, aerobics and swimming. Acquired results indicate that the range of PA amount in girls varies from 2,372 MET-min/week (15 year old girls to 4,467 MET-min/week (17 year old girls, while acquired results in boys varies from 2,535 MET-min/week (16 year old boys to 4,973 MET-min/week (17 year old boys. The results, if properly applied, could increase the total amount of PA in high school students and improve the effectiveness of school PE.

    Full Text Available Exertional heat stroke (EHS is one of the leading causes of sudden death in sport and physical activity. In American Football alone, there have been 46-documented EHS fatalities in the United States between 1995-2010.  In 2003, National Collegiate Athletics Association mandated pre-season heat acclimatization guidelines, which successfully decreased the number of heat stroke fatalities in collegiate American football. However, despite the advancement in modern medical care and increased awareness in heat safety, lack of appropriate on-site medical care is still contributing to EHS seen especially in the youth level. It is well established in scientific literature that fatalities as a result of EHS are largely preventable with proper education on the knowledge of recognition, treatment, and prevention of EHS. This document provides a review of the current best medical practices and evidence on the epidemiology, pathophysiology, risk factors, recognition, treatment, prevention, and return to play recommendations for EHS, specifically as they relate to sport and physical activity.

    Introduction Extracurricular school sports programs can provide adolescents, including those who are economically disadvantaged, with opportunities to engage in physical activity. Although current models favor more exclusionary interscholastic sports, a better understanding is needed of the potential effects of providing alternative school sports options, such as more inclusive intramural sports. The purpose of this study was to simulate the potential effect of implementing intramural sports programs in North Carolina middle schools on both the rates of sports participation and on energy expenditure related to physical activity levels. Methods Simulations were conducted by using a school-level data set developed by integrating data from multiple sources. Baseline rates of sports participation were extrapolated from individual-level data that were based on school-level characteristics. A regression model was estimated by using the simulated baseline school-level sample. Participation rates and related energy expenditure for schools were calculated on the basis of 2 policy change scenarios. Results Currently, 37.2% of school sports participants are economically disadvantaged. Simulations suggested that policy changes to implement intramural sports along with interscholastic sports could result in more than 43,000 new sports participants statewide, of which 64.5% would be economically disadvantaged students. This estimate represents a 36.75% increase in economically disadvantaged participants. Adding intramural sports to existing interscholastic sports programs at all middle schools in North Carolina could have an annual effect of an additional 819,892.65 kilogram calories expended statewide. Conclusion Implementing intramural sports may provide economically disadvantaged students more access to sports, thus reducing disparities in access to school sports while increasing overall physical activity levels among all children.

    Full Text Available Determining acceptable strategic goals requires analysis of the position of a sports organization within the sport world and wider business environment. A range of trends may affect development prospects and business activities of an organization. There are possibilities of population fluctuation (e.g. purchase power of winter sports practitioners, trends of economy, technological development, and legislation (e.g. prohibition of tobacco and alcohol advertisements, or activities of special interest groups (e.g. development of violence in sport. After clarifying its mission and goals, management of a sports organization reveals that some factors are important, while series of others are not

  1. Dependence of photosynthesis and energy dissipation activity upon growth form and light environment during the winter.

    2001-01-01

    Two very distinctive responses of photosynthesis to winter conditions have been identified. Mesophytic species that continue to exhibit growth during the winter typically exhibit higher maximal rates of photosynthesis during the winter or when grown at lower temperatures compared to individuals examined during the summer or when grown at warmer temperatures. In contrast, sclerophytic evergreen species growing in sun-exposed sites typically exhibit lower maximal rates of photosynthesis in the winter compared to the summer. On the other hand, shaded individuals of those same sclerophytic evergreen species exhibit similar or higher maximal rates of photosynthesis in the winter compared to the summer. Employment of the xanthophyll cycle in photoprotective energy dissipation exhibits similar characteristics in the two groups of plants (mesophytes and shade leaves of sclerophytic evergreens) that exhibit upregulation of photosynthesis during the winter. In both, zeaxanthin + antheraxanthin (Z + A) are retained and PS II remains primed for energy dissipation only on nights with subfreezing temperatures, and this becomes rapidly reversed upon exposure to increased temperatures. In contrast, Z + A are retained and PS II remains primed for energy dissipation over prolonged periods during the winter in sun leaves of sclerophytic evergreen species, and requires days of warming to become fully reversed. The rapid disengagement of this energy dissipation process in the mesophytes and shade sclerophytes apparently permits a rapid return to efficient photosynthesis and increased activity on warmer days during the winter. This may be associated with a decreasing opportunity for photosynthesis in source leaves relative to the demand for photosynthesis in the plant's sinks. In contrast, the sun-exposed sclerophytes - with a relatively high source to sink ratio - maintain PS II in a state primed for high levels of energy dissipation activity throughout much of the winter.

(56 boys and 64 girls), 12-13-yr. (68 boys and 68 girls), 14-15-yr. (70 boys and 71 girls), and 16-17-yr. (68 boys and 60 girls) was based on the Physical Activity Index derived from a questionnaire by Telama, Leskinen, and Young, and self-perceived endurance, strength, flexibility, and body composition. Questions about satisfaction with physical activity, participation in organized physical activity and competitions, or watching competitions were asked. Two EUROFIT tests were used, the 20-m endurance shuttle-run and sit-and-reach, plus the sum of 9 skinfold thicknesses. Children who participated in organized physical activity and in competitions had a higher Physical Activity Index. Passive watching of competitions was not related to children's physical activity or their perceived or measured motor abilities.

    Research suggests participation in youth sport does not guarantee physical activity (PA) guidelines are met. Studies indicate few children achieve recommended levels of moderate-to-vigorous physical activity (MVPA) during their youth sport involvement, and habitual levels of MVPA are below the recommended 60 min per day. Informed by self-determination theory, this study examined whether the coach-created social environment and related player motivation predict variability in objectively measured MVPA within the youth sport setting. Seventy three male youth sport footballers (Mean age = 11.66 ± 1.62) completed a multisection questionnaire assessing their perceptions of the social environment created in youth sport (autonomy supportive and controlling) and motivation towards their football participation (autonomous and controlled). Intensity of PA during youth sport was measured using accelerometers (GT3X, ActiGraph). Results supported a model in which perceptions of autonomy support significantly and positively predicted autonomous motivation towards football, which in turn significantly and positively predicted youth sport MVPA (% time). A significant indirect effect was observed for perceptions of autonomy support on youth sport %MVPA via autonomous motivation. Results have implications for optimising MVPA engagement during youth sport and increasing daily MVPA towards recommended and health-enhancing levels on youth sport days.

    The accommodation of 324 school children aged 10 to 16 years was studied before and after a 12-minute reading session. One hundred and twenty children (81 girls and 39 boys) were wind instrument players in school bands, 93 children (48 girls and 45 boys) trained in an individual sport, and 111 children (65 girls and 46 boys) having no such activities were studied as a control group. At the end of the reading session, decreased accommodation (7 diopters or less) was found in 19 (15.8%) of the musicians, in six (6.5%) of the athletes, and in six (5.4%) of the control group. The difference was significant between the musicians and the control group, but not significant between the athletes and the control group. The majority of the children with low accommodation were girls; there was only one boy with decreased accommodation in each of the three groups.

    2016-01-01

    Full Text Available The genetic and environmental factors and their interaction contribute to sports performance. So far, it has been identified a large number of genetic markers associated with sports performance and risk of sports injuries. Sports genomics is a relatively young scientific discipline and the necessary additional complex research on a large number of participants is required before scientific results in this field could be applicable in practice. At present, the application of tests based on genetic information for sport talent identification or recommendations for personalized training, in order to achieve optimal sport performance, is not scientifically justified. It is also necessary to carefully consider all the ethical issues related to such testing in children.

Methods Linkages between academic achievement and involvement in PE, school PA and sport programmes have been examined, based on a systematic review of currently available literature, including a comprehensive search of MEDLINE (1966 to 2007, PSYCHINFO (1974 to 2007, SCHOLAR.GOOGLE.COM, and ERIC databases. Results Quasi-experimental data indicate that allocating up to an additional hour per day of curricular time to PA programmes does not affect the academic performance of primary school students negatively, even though the time allocated to other subjects usually shows a corresponding reduction. An additional curricular emphasis on PE may result in small absolute gains in grade point average (GPA, and such findings strongly suggest a relative increase in performance per unit of academic teaching time. Further, the overwhelmingly majority of such programmes have demonstrated an improvement in some measures of physical fitness (PF. Cross-sectional observations show a positive association between academic performance and PA, but PF does not seem to show such an association. PA has positive influences on concentration, memory and classroom behaviour. Data from quasi-experimental studies find support in mechanistic experiments on cognitive function, pointing to a positive relationship between PA and intellectual performance. Conclusion Given competent providers, PA can be added to the school curriculum by taking time from other subjects without risk of hindering student academic achievement. On the other hand, adding time to "academic" or "curricular" subjects by taking time from physical education programmes does not enhance grades in these subjects and may be detrimental to health.

    The aim of this study was to provide initial evidence of validity and reliability of scores derived from the Activity Context in Youth Sport Questionnaire (ACYSQ), an instrument designed to offer a comprehensive assessment of the activities adolescents take part in during sport practices. Two studies were designed for the purposes of item development and selection, and to provide evidence of structural and criterion validity of ACYSQ scores, respectively (N = 334; M age = 14.93, SD = 1.76 years). Confirmatory factor analysis (CFA) supported the adequacy of a 20-item ACYSQ measurement model, which was invariant across gender, and comprised the following dimensions: (1) stimulation; (2) usefulness-value; (3) authenticity; (4) repetition-boredom; and (5) ineffectiveness. Internal consistency reliability estimates and composite reliability estimates for ACYSQ subscale scores ranged from 0.72 to 0.91. In regression analyses, stimulation predicted enjoyment and perceived competence, ineffectiveness was significantly associated with perceived competence and authenticity emerged as a predictor of commitment in sport. These findings indicate that the ACYSQ displays adequate psychometric properties and the use of the instrument may be useful for studying selected activity-based features of the practice environment and their motivational consequences in youth sport.

    Winter weather conditions may negatively influence participation of older adults in daily physical activity (PA). Assess the influence of winter meteorological variables, day-time peak ambient temperature, windchill, humidity, and snow accumulation on the ground to accelerometer measured PA values in older adults. 50 community-dwelling older adults (77.4±4.7yrs; range 71-89; 12 females) living in Southwestern Ontario (Latitude 42.9°N Longitude 81.2° W) Canada, wore a waist-borne accelerometer during active waking hours (12h) for 7 consecutive days between February and April 2007. Hourly temperature, windchill, humidity, and snowfall accumulation were obtained from meteorological records and time locked to hourly accelerometer PA values. Regression analysis revealed significant relationships between time of day, ambient daytime high temperature and a humidity for participation in PA. Windchill temperature added no additional influence over PA acclamation already influenced by ambient day-time temperature and the observed variability in PA patterns relative to snow accumulation over the study period was too great to warrant its inclusion in the model. Most PA was completed in the morning hours and increased as the winter month's transitioned to spring (February through April). An equation was developed to adjust for winter weather conditions using temperature, humidity and time of day. Accurate PA assessment during the winter months must account for the ambient daytime high temperatures, humidity, and time of day. These older adults were more physically active during the morning hours and became more active as the winter season transitioned to spring. Copyright © 2017 Elsevier B.V. All rights reserved.

    Activities concerning the fight against doping with regard to the Paralympic Games have been initiated in 1984, when first doping controls were conducted. The foundation of the International Paralympic Committee exactly 20 years ago (1989) considerably supported systematic sports drug-testing programs specifically designed to meet the particular challenges related to disabled sports, which yielded a variety of adverse analytical findings (e.g., with anabolic steroids, diuretics, corticosteroids, and stimulants) especially at Paralympic Summer Games. In Germany, doping controls for handicapped athletes were established in 1992 and have been conducted since by the National Paralympic Committee Germany and the National Anti-Doping Agency. Also here, various analogies in terms of antidoping rule violations were found in comparison to doping controls of nondisabled athletes. In the present article, available numbers of samples analyzed at Paralympic Summer and Winter Games as well as within the doping control program for disabled sports in Germany are summarized, and particularities concerning sample collection and the doping method termed boosting are presented.

    The present study asses the prevalence of depressive symptoms among college students in Split, Croatia, and positive influence of sport activity on decreasing the depression symptoms. Authors screened all 664 college students of the first year of study. All of them were over the 18 years and the mean age was 19.4 +/- 1.2 years. There were 466 females (70.2%) and 178 (26.8%) males. They answered The Beck Depression Inventory (BDI) and questionnaire about their sport activity (no sport activity, recreational and active in sports). For the purpose of the analysis depressive symptoms were defined as a score of > 11. Chi-square and Mann-Whitney test were used for data analysis. 9.4% of the students had significant depression symptoms (score > 11). No one student had score > 26 (symptoms of major depression). Statistically significant lower score on BDI have students who are active in sports (score median = 3) compared to group of recreational (score median = 4) and in correlation to group who are not active in sports (score median = 5) (Kruskal-Wallis: p depressions symptoms, while in the group of non active in sports (N = 60) are 18 depressive (chi2-test: p = 0,005). Females are statistically more depressed than males (chi2-test: p = 0.01). In the female group 49 (10.5%) are depressed, and in the male group are 9 (5%). Compared to gender in separate analysis we did not find correlation of decreasing depression symptoms and sport activity among males (chi2-test: p = 0.47), while in females we find that sport activity has significant effect (chi2-test: p = 0.026). Our results shoved moderate values of depression symptoms among college population in Split, Croatia. More females than males experienced depressive symptoms. While sport activity did not have significant influence on the depression in male population, it has significant influence in reducing the depression symptoms among females.

    Maintenance of motor activity by autonomic nervous system is adjusted, mainly, by congenital reflexes. But alongside with inborn reactions to muscular work at formation of motor skill the specific vegetative components are formed to the given kind of sport activity. The aim of our research was revealing those physiological features which are characteristic for an organism of the high skilled sportsmen, with large experience of training and competitive activity. At tested football players have been measured some parameters of external respiration and cardiovascular system. In our investigation it is shown, that programming of the same productivity of work and the same effect are achieved by unequal vegetative support and a different combination of separate components of the general vegetative reaction. Definition and a due estimation of these intermediate parameters in conditions of rest and at physical loading enables objective judgement about a functional condition of the sportsman, about weak parts in system of maintenance of a homeostasis of an organism and directions of accomplish the functioning of the basic effectors.

    Overweight and obesity in Australia is an emerging health concern. Obesity prevention initiatives must consider both physical activity and nutrition to be effective. Community sports venues have the capacity to promote healthy lifestyles through physical activity as well as healthy food choices. A telephone survey was conducted on parents of children aged 5-17 years in NSW to determine the nature of food and beverages purchased by children at community sporting venues and to determine parent's perception of the role that government should play in regulating the types of food and beverages sold at these outlets. The majority of canteens at children's sporting venues were considered to sell mostly unhealthy food and beverages (53%). Very few parents reported that canteens sold mostly healthy food and beverages. Parents reported that their child's most frequently purchased food and beverage items at outdoor sports fields were water, chocolate and confectionery, soft drink and sports drinks, and ice cream. At community swimming pools the most frequently purchased items were ice cream, followed by snack foods, including chips, cakes and biscuits. Most parents (63%) agreed that government should restrict the types of food and beverages that can be sold at children's sporting venues. Children are receiving inconsistent health messages at sporting venues, with healthy lifestyles being promoted through sports participation, but unhealthy dietary choices being provided at sports canteens.

    Conclusion: Fostering more empowering youth sport environments may hold implications for the prevention of excess adiposity, through encouraging higher habitual MVPA engagement. Findings may inform the optimal design of youth sport settings for MVPA promotion, and contribute towards associated healthy weight maintenance amongst youth active in this context. Longitudinal and intervention studies are required to confirm these results.

  13. Three people can synchronize as coupled oscillators during sports activities.

    2011-10-01

    Full Text Available We experimentally investigated the synchronized patterns of three people during sports activities and found that the activity corresponded to spatiotemporal patterns in rings of coupled biological oscillators derived from symmetric Hopf bifurcation theory, which is based on group theory. This theory can provide catalogs of possible generic spatiotemporal patterns irrespective of their internal models. Instead, they are simply based on the geometrical symmetries of the systems. We predicted the synchronization patterns of rings of three coupled oscillators as trajectories on the phase plane. The interactions among three people during a 3 vs. 1 ball possession task were plotted on the phase plane. We then demonstrated that two patterns conformed to two of the three patterns predicted by the theory. One of these patterns was a rotation pattern (R in which phase differences between adjacent oscillators were almost 2π/3. The other was a partial anti-phase pattern (PA in which the two oscillators were anti-phase and the third oscillator frequency was dead. These results suggested that symmetric Hopf bifurcation theory could be used to understand synchronization phenomena among three people who communicate via perceptual information, not just physically connected systems such as slime molds, chemical reactions, and animal gaits. In addition, the skill level in human synchronization may play the role of the bifurcation parameter.

    AIM: The main aim of this study was to examine differences in sport participation motives, the frequency of engaging in sports activities according to gender, region and field of study, but also the association between the incidence of engaging in sports activity and the motivation for sports activity of students at the University of Ljubljana. MATERIAL AND METHODS: Five thousand two hundred seventy-one students completed The Exercise Motivations Inventory (EMI-2), with additional questions about 12 socio-demographic parameters. RESULTS: The results reveal that most of the students are engaged in unorganized sports activities. Male students engage in sports activity more often than female students do. For male students, dominant participation motives are enjoyment, challenge, social recognition, affiliation, competition and strength but also endurance, for female students these are: stress and weight management, revitalisation, ill-health avoidance, positive health, appearance and nimbleness. Gender differences in participation motives are partly reflected also in differences according to the field of study. The correlations between the frequency of engaging in sports activity and the participation motives are mainly statistically significant. We did not find any significant differences in participation motives by region. CONCLUSION: In spite of these discouraging findings, increasing physical activity among students continues to be a national priority. PMID:29104693

    To examine how social support, participation in intramurals, varsity and community sports are associated with physical activity among Ontario secondary school students, and explore gender differences in the prevalence of physical activity and participation in school- and community-based sports. Data from 25,416 students (grades 9-12) attending 76 Ontario secondary schools were collected using the School Health Action, Planning, and Evaluation System (SHAPES). Logistic regression analyses examined how social support and school- and community-based sports participation were associated with physical activity. Males and females with low social support for physical activity were less likely to be active than their lower-risk peers (males: OR 0.61; females: OR 0.72). Males and females were more likely to be active if they participated in intramural activities (males: OR 1.92; females: OR 1.55), varsity sports (males: OR 1.93; females: OR 1.77), or community sports (males: OR 2.84; females: OR 2.90). Since students with low social support for physical activity were less likely to be active, interventions to increase support and engagement in physical activity should be targeted to these students. In addition, considering that participation in school- and community-based sports increases the likelihood that students were active, practitioners should seek to enhance opportunities for participation in and access to these programs in order to increase the level of activity obtained by students.

    The role of sports in decreasing the prevalence of many diseases has led to a growing interest in the field of sport and exercise medicine. But sport and exercise medicine still remains new to the Arab world, waiting to be explored. The aim of this study is to describe and characterise sport and exercise medicine research activity in the Arab world between 2002 and 2016. The PubMed database was used to search for publications related to sport and exercise medicine. Publications were classified according to the country of origin and filtered to include publications between 2002 and 2016. Research output was analysed with respect to gross domestic product (GDP) and population of each country. A total of 1148 papers related to sport and exercise medicine were found to be published in the Arab countries between 2002 and 2016. Sport-and-exercise-medicine-related publications constituted 0.86% of the total biomedical research papers published in the Arab world and 0.49% of the world's sport and exercise medicine literature. The number of sport-and-exercise-medicine-related publications per country ranged from zero to 352, with Qatar occupying the top spot. Tunisia ranked first with respect to publications per average GDP, while Qatar ranked first with respect to publications per average population. Comoros, Mauritania, Somalia, Sudan and Yemen were found to have no publications related to sport and exercise medicine. Sport and exercise medicine is a novel field in the Arab world. Recognising the barriers facing sport and exercise medicine research and exploring them meticulously remains an essential part of the plan to improve the Arab world's output and contribution in this field.

    Full Text Available The purpose of this study was to examine the participation motives of youth from different sport branches and examine the differences with respect to different demographic variables. The study was conducted on 85 girls and 202 boys from different sport branches in Turkey. The average age of the participants were 14.29 years (SD=1.1. The “Participation Motivation Questionnaire (PMQ” (Gill, Gross and Huddleston (1983 was administered on the participants. The reliability and validity of the PMQ was tested by Oyar, Aşçı, Çelebi and Mülazımoğlu (2001. The scale consisted of 30 items and 8 subscales. All items were measured and sorted using a three-point Likert scale. Descriptive statistics and were performed on all variables including means and standard deviations. Independent Samples t-test was also used to determine differences between the scores acquired from the scale and some independent variables. Analysis indicated significant differences in achievement/status (t= 2.71; p < 0.05, team affiliation (t= 2.12; p < 0.05 and friendship (t= 3.81; p < 0.01 subscales between girls and boys. Boys had higher scores than the girls. There were significant differences in achievement/status (t= 2.52; p < 0.01, team affiliation (t= 2.33; p < 0.01, energy release/fitness (t= 2.33; p < 0.05 and competition (t= 2.50; p < 0.01 subscales with regard to sport experience. Less experienced participants had lower scores than the more experienced. As a result, it can be concluded that based on the mean ratings of each of the 30 participation motives, “improve my skills” and “to raise my sport branch” were the most important participation motives for the participants.

    To evaluate the prevalence of urinary stress incontinence (USI) in menstruating women practising recreational sports activity, to detect specific sports with a stronger association with urinary incontinence (UI) and to evaluate risk factors possibly related to this condition. Epidemiological study. Non-competitive sports organisations in the province of Varese, Italy. 679 women of fertile age, practising recreational sports activity. Anonymous questionnaire on UI. The questionnaire included questions about patients' general characteristics, occurrence of UI in relation to sport or daily general activities, time of onset of this condition, frequency of leakage episodes, correlation of incontinence with types of movements or sports, subjective impression of being limited on such occasions and/or necessity to modify the type of sport. UI was reported by 101 women (14.9%). Of these, 32 (31.7%) complained of UI only during sports activity, 48 (47.5%) only during daily life and 21 (20.8%) in both circumstances. Body mass index and parity were significantly associated with the risk of UI. Looking at the different sports activities, a higher rate of incontinence was found in women participating in basketball (16.6%), athletics (15%), and tennis or squash (11%). 10.4% of women abandoned their favourite sport, because of USI, and a further 20% limited the way they practised their favourite sport to reduce leakage episodes. Female UI affects a significant proportion of young women practising non-competitive sports activity; it can cause abandonment of the sport or limitation of its practice.

    We examined the demographic, medical and behavioral correlates of participation and interest in extreme sport/adventure activities (ESAA) in gynecologic cancer survivors. A random sample of 621 gynecologic cancer survivors in Alberta, Canada, completed a mailed self-report questionnaire assessing medical, demographic, and behavioral variables and participation and interest in ESAA. Multivariate analyses revealed that gynecologic cancer survivors were more likely to participate in ESAA if they met aerobic exercise guidelines (OR=1.75 [95%CI:1.02-2.99]), had better general health (OR=1.71 [95%CI: 1.01-2.90]), had cervical or ovarian cancer (OR=1.95 [95%CI:0.97-3.93]), were employed (OR=1.71 [95%CI:0.95-3.08]), and were of healthy weight (OR=1.58 [95%CI:0.93-2.68]). Moreover, gynecologic cancer survivors were more likely to be interested in trying an ESAA if they had cervical or ovarian cancer (OR=1.76 [95%CI:0.94-3.27]) and were meeting the strength exercise guidelines (OR=1.68 [95%CI:0.95-2.98]). Medical, demographic, and behavioral variables correlate with participation and interest in ESAA in gynecologic cancer survivors. The pattern of correlates suggests that gynecologic cancer survivors are more likely to participate in ESSA if they have the physical capability and financial resources. Interventions to promote ESAA in gynecologic cancer survivors need to address these 2 key barriers.

    We re-examined children who had previously been declared eligible to participate in competitive sports activities for cardiac disorders, using cardiac investigation protocol. Total of 250 children (224 males [89.6%], and 26 females [10.4%]) between the ages of 8 and 17 years who had just started or were already engaged in sports activities were included in the study. Participants had detailed physical examination evaluated by a pediatric cardiologist. Those with findings suggesting cardiac disorder in their history and/or physical examinations, and/or 12-channel electrocardiography (ECG) were examined with echocardiography (ECHO), 24-hour Holter monitoring, and exercise test. Mean duration of participation in sports activities was 13 months. Among all, 10.4% of the children had abnormalities on ECG. ECHO demonstrated cardiomyopathy in 1, mitral valve prolapse in 2, tricuspid insufficiency in 2, and mitral insufficiency in 1 participant. Holter monitoring revealed non-sustained ventricular tachycardia attacks in 1, and supraventricular tachycardia in another child. Three were ultimately disqualified from partaking in competitive sports. Sports and medical communities must work together to establish study protocols to prevent sudden death related to sports and to make these activities safer for athletes. Pediatric cardiology consultation for young athletes before they start sports activities is needed.

    Full Text Available The main purpose of this research was to analyse the gender differences among students at the University of Ljubljana concerning the popularity of sports and participation in different types and modes of sport activities. The research was done in the 2013 academic year on a random sample of 3% of the students (N=1390. A questionnaire about students’ lifestyles was used (Majerič, 2013. In this study, two variables were analysed: the popularity of different sport activities, and different types and modes of sport activities. The data of the variables were analysed with SPSS for Windows. The basic statistical parameters for both variables were calculated. To calculate the gender differences, a t-test for independent samples and a Mann-Whitney U test were run. An analysis of the popularity of different sport activities showed that gender differences were statistically significant in jogging (p=0.000, walking (p=0.000, football (p=0.000, basketball (p=0.000, fitness (p=0.001, aerobics (p=0.002, and dance activities (p=0.009. Analysis of the types and modes of sport activities among students showed that 63.90% of male students and 68.10% of female students were engaged in unorganized types of sport. Gender differences were found to be statistically significant in two types of sport activities: engaged organized in clubs–competitive out of faculty (p=0.000 and engaged in sport organized at the faculty–competitive (p=0.000. Our findings and conclusions provide useful guidance for the closer and wider professional public.

    We developed a technique - based on alpha particle track detection using CR-39 - where the activity originated from indoor radon can be potentially separated into three fraction: (i) radon in the air, (ii) radon daughters (RD), 218 Po and 214 Po, in the air and (iii) RD plated-out on the detector surface during exposure. In this work only a partial separation was carried out, then our results are limited to radon plus RD in the air and RD attached to detector surface. These activities can be separated if size and gray level of the round tracks are measured using an automatic optical microscopy system.Our group carried out an indoor radon and radon daughters (RD) survey in Campinas made up by a summer (November, 96 to May, 97) and a winter (May, 97 to November, 97) exposure, where the detectors were placed in the same rooms of the same dwellings (approximately 100) in both cases. Comparing winter and summer alpha activity for the detectors analyzed up to now, approximately 45 dwellings, we observed that: i) it seems that the source of radon is the material (brick and concrete mainly) making up walls, floor and ceiling of the dwellings, ii) there is no clear relationship between intensity of aeration and the activities measured in this work, and iii) the average ratio between winter and summer activity in the air (radon plus RD) is approximately equal to similar ratios observed in other countries, but for radon only.

    Full Text Available Sufficient and regular physical activity is considered a protective factor, reducing the onset of secondary disability conditions in adolescents with chronic diseases and functional limitations. The aim of this study was to explore whether participation in organized sport may be associated to higher levels of physical activity in adolescents with functional limitations, based on a national representative sample. Data from the Health Behaviour in School-aged Children (HBSC study collected in Finland from two data collection rounds (2002 and 2010 were conducted and pooled from adolescents aged between 13 and 15 years old with functional limitations (n = 1041. Differences in self-reported physical activity over the past week and participation in organized sport activity were analysed for each function. Overall, four in ten (n = 413 participated in organized sport and were significantly (p < 0.001 more physically active (mean = 4.92days, SD = 1.81 than their non-participating (mean = 3.29, SD = 1.86 peers with functional limitations. Despite low population prevalence, adolescents with epilepsy or visual impairments were the least active if they were not participating in organized sport, yet were the most active if they were involved in organized sport. Participating in organized sport appears to be an important factor promoting resources for maintaining recommended levels of physical activity in Finnish adolescents with functional limitations.

    This microeconometric study analyzes the effects of individual leisure sports participation on long-term labour market variables, health and subjective well-being indicators for West Germany based on individual data from the German Socio-Economic Panel study (GSOEP) 1984-2006. Econometric problems due to individuals choosing their own level of sports activities are tackled by combining informative data and flexible semiparametric estimation methods with a specific way to use the panel dimension of the data. The paper shows that sports activities have sizeable positive long-term labour market effects in terms of earnings and wages, as well as positive effects on health and subjective well-being.

    To date, studies examining physical activity (PA) levels have largely been dedicated to the school setting, while there is little known about the activity levels of children who participate in traditional or summer day camps. Participants were 83 11- to 12-year-old campers who partook in either Sport Education or traditional instruction at a large residential summer camp. All lessons were video recorded and coded using the System for Observing Fitness Instruction Time (SOFIT), which categorizes PA levels as well as contextual characteristics. Results indicated that campers who participated in Sport Education spent a higher percentage of time (61.6%) engaged in moderate to vigorous activity than campers in the traditional activity unit (42.2%). In addition, campers spent less time idly within Sport Education (27.9%), than its counterpart (39.5%). These findings indicate that utilizing the Sport Education model may provide campers with higher levels of PA within this context.

    The contribution of sports related factors to predicting long-term physical activity (PA) are unclear. The purpose of this study is to examine tracking of PA during key transition periods in youth and to determine the longitudinal associations between sports club participation and PA. Participants (n = 873, baseline age 10 to 18 years) completed self-report surveys in 2009 and 2014 that included the PACE+ PA tool and sports club participation questions. Spearman correlations assessed PA tracking. ANCOVA analyses examined predictors (sports participation at baseline) of PA (follow-up), adjusting for (a) age and sex; and (b) age, sex, and baseline PA. Tracking of PA was weak-to-moderate (ρ = .16 to .47). Greater sports participation frequency at baseline significantly predicted PA at follow-up (P sports at an elite level had a medium-to-large effect on PA levels 5 years later [d = .75 adjusting for (a); d = .60 adjusting for (b)]. PA should be promoted in youth as tracking coefficients suggest it can, to an extent, continue into later life. The standard achieved in sport has a role in predicting later PA. PA promotion strategies should include frequent, high quality opportunities for sports participation.

    This study described how the Dutch and Canadian governments promote high performance sports, recreational sports, and physical activity (PA) among adults with disabilities on a national level. An internet-based study was conducted to identify and select relevant documents and websites containing information about the national approach to promote disability sports and physical activities in the Netherlands and Canada. Both governments promote high performance sports in similar ways, but use different strategies to promote recreational sports and physical activities. The Dutch approach is characterized by using time-limited programs focusing on enhancement of sports infrastructure and inter-sector collaboration in which municipalities have key roles. The Canadian government promotes recreational sports in disabled populations by supporting programs via bilateral agreements with provinces and territories. Furthermore, the level of integration of disability sports into mainstream sports differs between countries. The findings of this study may inspire policy makers from different countries to learn from one another's policies in order to optimize national approaches to promote disability sports and PA on all levels. Implications for rehabilitation It is recommended for policy makers of national governments to develop and implement policy programs that promote sports and physical activities among people with disabilities because of its potential impact on functioning, participation, quality of life, and health. Insight into national approaches to promote sport and physical activities is relevant for rehabilitation practice to understand ongoing opportunities for people with disabilities to stay physically active after rehabilitation through participation in home and/or community-based sport and physical activities. It seems worthwhile to integrate activities to promote sport and physical activities in rehabilitation in such a way that it fits with the current

    Across the entire distribution of a species, populations may have variable responses to environmental perturbations. Many bat species experience mortality in large portions of their range during hibernation and along migratory paths to and from wintering grounds, from White-nose syndrome (WNS) and wind energy development, respectively. In some areas, warm temperatures may allow bats to remain active through winter, thus decreasing their susceptibility to WNS and/or mortality associated with migration to wintering grounds. These areas could act as a refugia and be important for the persistence of local populations. To determine if warmer temperatures affect bat activity, we compared year-round activity of bat populations in the Coastal Plain and Piedmont of North Carolina, USA, two regions that differ in winter temperature. We established six recording stations, four along a 295-kilometer north-south transect in the Coastal Plain, and two in the Piedmont of North Carolina. We recorded bat activity over two years. We supplemented our recordings with mist-net data. Although bat activity was lower during winter at all sites, the odds of recording a bat during winter were higher at Coastal Plain sites when compared with Piedmont sites. Further, bats in the Piedmont had a lower level of winter activity compared to summer activity than bats in the Coastal Plain that had more similar levels of activity in the winter and summer. We found high bat species richness on the Coastal Plain in winter, with winter-active species including those known to hibernate throughout most of their range and others known to be long distance migrants. In particular, two species impacted by WNS, the northern long-eared bat (Myotis septentrionalis) and tricolored bat (Perimyotis subflavus), were present year round in the Coastal Plain. The tricolored bat was also present year-round in the Piedmont. In the Coastal Plain, the long distance migratory hoary bat (Lasiurus cinereus) was active in the

    Full Text Available Sport and related physical activity education are not being employed in the best possible ways in the developed world because the decision-makers in society don’t truly understand the situation. Illogically, people of all ages in the developed world are not getting sufficient physical activity, whereas those in the undeveloped world are getting too much! In addition, the author questions the vast overemphasis on highly competitive sport at the various levels including the Olympic Games. Further, the situation for the majority of “special-needs” people is poor including those who are exploited by sport competition overemphasis. Six different types of selected competencies are recommended for all children and youth within the educational-system experience. Finally, the author asks five specific questions that should be considered as we seek to improve the overall situation. Keywords: sport and physical activity education, memes, the Olympic Games

    Studies have shown participation in sport is lower among girls than boys, decreases as students matriculate through high school, is lowest among Black and Hispanic girls and has a positive relationship with SES. With sport recognized as a contributor to physical activity and health in adolescents, consideration of diminishing rates of participation appears warranted. The purpose of this study was to identify patterns related to differences in self-reported sport participation between genders, ethnic groups, grades and SES. This study was a cross-sectional, secondary analysis of data collected for a sport interest survey. All students in grades 8-11 attending middle and high schools were provided an opportunity to participate in the survey. Data from 49,832 students were analyzed. Among the participants, Black girls participated more and White girls participated less than expected. Black boys participated more while White and Asian boys participated less than expected. Reported sport participation was high compared with national data when analyzed by gender and ethnic group. Sport participation was higher in low SES schools compared with high SES schools. The importance of sport as a source of physical activity in underserved groups is significant.

    The increased prevalence of childhood obesity has also been attributed to low physical activity (PA) levels. Understanding factors affecting child PA levels is especially important considering the benefits PA offers to youth. This study therefore examined different correlates affecting habitual PA and sports participation in primary school children. Height and weight were measured during a school visit in 1714 children (7.1 ± .6 years). PA and behavioural correlates were assessed by parental questionnaire. The effect of various correlates on PA as well as participation in organized sports was assessed using logistic regression analysis. Significant correlates of PA and sports participation were engagement in sporting activities outside of clubs and children's weight status. Playing outdoors for more than 60 min/day was significant for PA, having well educated parents and being male. Participation in sports was influenced by children's media consumption, active travel to school and having active parents. No influence was found for migration, income, parental weight status and health consciousness. In this study, a multiplicity of independent correlates of PA and sports participation, which require a broad approach to promote an active lifestyle, have been considered. Understanding these factors might support the development of effective health-promoting interventions. Copyright © 2014 The Authors. Published by Elsevier Ltd.. All rights reserved.

    Full Text Available A case – control study of 257 women with breast cancer and 565 control women was conducted to investigate the effect of life-time sport activity on breast cancer risk. Information was collected by questionnaire about sports played, frequency of participation and duration. The activity levels were determined using frequency variable weighted for metabolic equivalents of energy expenditure (MET. Multivariate logistic regression analyses were used to compute odds ratios (ORs and 95% confidence intervals (CIs. A full assessment of confounding and effect modification was undertaken. The odds ratios for increasing tertiles of sport activity were 1.00 (referent, 0.50 (CI: 0.33-0.76 and 0.44 (CI: 0.28-0.64, respectively (P-trend = 0.000. Comparing sport active women to inactive women the OR was 0.49 (CI: 0.35-0.69. Models stratified according to body mass index, age at menarche, age at first full term pregnancy, intake of vegetables and fruits, and experience of stress were examined. In models stratified the risks of breast cancer were also reduced with higher levels of activity in sport. The conclusion is that women who participated in sports have a reduced risk of breast cancer.

    Full Text Available Abstract Background The benefits of physical activity on physical and mental health are well known. The accessibility of sports facilities is reported to have considerable association with the amount of physical activity a person participates in. Therefore, we investigated the association between subjectively assessed accessibility of sports facilities and physical activity among Korean adults. Methods We obtained data from the 2012 Community Health Survey. Physical activity was measured based on weekly metabolic equivalent task (MET hours according to the International Physical Activity Questionnaire (IPAQ. Sociodemographic, economic, and health variables were used as covariates in a logistic regression model. Results A total 201,723 participants were included in this study. Participants with easy access to sports facilities participated in physical activity more often than those without easy access (OR = 1.16, 95 % CI 1.13–1.20. More physical activity was generally observed if participants had a history of depression or if participants were among the white-collar or urban subgroups. Conclusion Our results showed that the accessibility of sports facilities is associated with physical activity. Therefore, it is crucial to consider the accessibility of sports facilities when promoting an environment conducive to physical activity or designing programs for enhancing physical activity.

    Full Text Available Abstract Background Since knee complaints are common among athletes and are frequently presented in general practice, it is of interest to investigate the type of knee complaints represented in general practice of athletes in comparison with those of non-athletes. Therefore, the aim of this study is to investigate the differences in type of knee complaints between sport participants, in this study defined as athletes, and non-sport participants, defined as non-athletes, presenting in general practice. Further, differences in the initial policy of the GP, medical consumption, and outcome at one-year follow-up were also investigated. Methods Patients consulting their GP for a new episode of knee complaints were invited to participate in this prospective cohort study. From the total HONEUR knee cohort population (n = 1068 we extracted patients who were athletes (n = 421 or non-athletes (n = 388. Results The results showed that acute distortions of the knee were significantly more diagnosed in athletes than in non-athletes (p = 0.04. Further, more athletes were advised by their GP to 'go easy on the knee' than the non-athletes (p Conclusion There are no major differences in the diagnosis and prognosis of knee complaints between athletes and non-athletes presented to the GP. This implies that there are no indications for different treatment strategies applied in both groups. However, athletes are more often advised to 'go easy on the knee' and to rest than non-athletes. Further, there is a trend towards increased medical consumption among athletes while functional disability and pain are lower than among the non-athletes.

    Military and civil defense personnel are often involved in complex activities in a variety of outdoor environments. The choice of appropriate clothing ensembles represents an important strategy to establish the success of a military mission. The main aim of this study was to compare the known clothing insulation of the garment ensembles worn by soldiers during two winter outdoor field trials (hike and guard duty) with the estimated optimal clothing thermal insulations recommended to maintain thermoneutrality, assessed by using two different biometeorological procedures. The overall aim was to assess the applicability of such biometeorological procedures to weather forecast systems, thereby developing a comprehensive biometeorological tool for military operational forecast purposes. Military trials were carried out during winter 2006 in Pokljuka (Slovenia) by Slovene Armed Forces personnel. Gastrointestinal temperature, heart rate and environmental parameters were measured with portable data acquisition systems. The thermal characteristics of the clothing ensembles worn by the soldiers, namely thermal resistance, were determined with a sweating thermal manikin. Results showed that the clothing ensemble worn by the military was appropriate during guard duty but generally inappropriate during the hike. A general under-estimation of the biometeorological forecast model in predicting the optimal clothing insulation value was observed and an additional post-processing calibration might further improve forecast accuracy. This study represents the first step in the development of a comprehensive personalized biometeorological forecast system aimed at improving recommendations regarding the optimal thermal insulation of military garment ensembles for winter activities.

    To explore the perceptions of health and physical activity, and the associations between these two areas from a theoretical lifestyle perspective. Data was collected by means of a self-administered questionnaire, among 3019 adults attending centres for preventive medicine in France. Correspondence analysis examined the significance of the relationships between perceptions of health and perceptions of sports and physical activity. Four principal types of subjects emerged from the factor analyses expressing four different lifestyle patterns. "Non physically active lifestyle: a feeling of not being healthy", "Physically active lifestyle, pleasure/leisure-oriented", "Necessarily physically active lifestyle, regardless of health", "Physically active lifestyle aimed at stress relief". The sociological approach helps tackle sports and physical activity as behaviour patterns but also and especially as a health orientation connected with the socio-economical climate. This approach also gives sports practice back its meaningful cultural dimension.

  7. Child Protection in Sport: Reflections on Thirty Years of Science and Activism

    2014-07-01

    Full Text Available This paper examines the responses of state and third sector agencies to the emergence of child abuse in sport since the mid-1980s. As with other social institutions such as the church, health and education, sport has both initiated its own child protection interventions and also responded to wider social and political influences. Sport has exemplified many of the changes identified in the brief for this special issue, such as the widening of definitional focus, increasing geographic scope and broadening of concerns to encompass health and welfare. The child protection agenda in sport was initially driven by sexual abuse scandals and has since embraced a range of additional harms to children, such as physical and psychological abuse, neglect and damaging hazing (initiation rituals. Whereas in the 1990s, only a few sport organisations acknowledged or addressed child abuse and protection (notably, UK, Canada and Australia, there has since been rapid growth in interest in the issue internationally, with many agencies now taking an active role in prevention work. These agencies adopt different foci related to their overall mission and may be characterised broadly as sport-specific (focussing on abuse prevention in sport, children’s rights organisations (focussing on child protection around sport events and humanitarian organisations (focussing on child development and protection through sport. This article examines how these differences in organisational focus lead to very different child protection approaches and “solutions”. It critiques the scientific approaches used thus far to inform activism and policy changes and ends by considering future challenges for athlete safeguarding and welfare.

    The aim of the study was to investigate the effects of sport activity on health-related quality of life (HRQoL) of solid organ transplant recipients participating in sports competitions. A group of 168 sportive transplanted patients (STP), a group of 97 nonsportive transplanted patients (NSTP), and a group of 152 sportive healthy controls (SHC) were compared on the eight scales of the SF-36 questionnaire. STP and NSTP reported significantly lower scores than SHC on the physical functioning scale. STP did not differ from SHC in the Role-Physical, General Health, and Vitality scales, while NSTP reported significantly lower scores. STP obtained higher scores than NSTP and SHC on Mental Health. Among STP, the effect of quantity of sport activity was significant on General Health and Role Emotional, with more sport activity associated with higher HRQoL. Organ failure and post-transplant therapies may have negative consequences on HRQoL. Sports activities and participation in sports competitions can reduce this impact, improving general and psychological functioning of solid organ transplant recipients.

Material & Methods: the special surveys of students and teachers of KhSAPC, and also students, who train in sports club "Politekhnik", and the students who are engaged in sports sections NLA were conducted for the solution of purposes. Results: the most important qualities of the personality which sports activities influence are: formation of "confidence", "emotional stability", and "orientation to achievement" at sportsmen. According to most of the interviewed sportsmen and experts, the authority of the coach is not significant factor which influences the identity of sportsmen. Conclusions: it is established as a result of the conducted researches that sports activities most of all influence the formation of confidence, emotional stability and orientation to achievement at sportsmen. Results of the research demonstrate also that the identity of the sportsman is most influenced by the competitive relationship which develops in the course of competitive activity. Results of the research also indicate disturbing tendency which is shown that most of sportsmen connect the end of their sports career with injuries.

    We examined the long-term effects of youth leisure time physical activity (LTPA) and sports participation on the prevalence of chronic work stress in adulthood. Participants (326 men and 338 women) aged 9 to 18 years were initially enrolled in 1980 and followed until 2007. Data were collected using questionnaires and bicycle ergometry in a subgroup. High youth LTPA and sports participation predicted lower chronic job strain in both sexes. The association was mediated by type A leadership. Participation and persistence in organized youth sports followed a similar pattern. In the subgroup, adult physical fitness only partly accounted for the association. Sustained involvement in youth physical activity and sport lasting at least 3 years is associated with reduced chronic job strain in adulthood. The association was partially explained by type A leadership and physical fitness.

    This study evaluated the prevalence of physical activity through the practice of sports in adolescents from schools in two Brazilian cities and a Portuguese school, and its association with independent variables, such as gender and age. A cross-sectional study was conducted of schoolchildren from two cities in Brazil and one in Portugal. The total study sample was 3694 subjects (1622 males and 1872 females). Physical activity levels were assessed using Baecke's questionnaire. Body weight was measured on electronic scales and stature was measured with a portable wooden stadiometer. Numerical variables were expressed as mean, categorical variables were expressed as percentages and the chi-square test analyzed associations. The prevalence of no sport was high (39.7%), being higher in the Portuguese school than in the Brazilian schools (p sports practice than girls (p sport than the boys and with this imbalance likely to be higher in adolescents.

    Because sustained physical activity is important for a healthy life, this paper examined whether a greater diversity of sport activities during adolescence predicts higher levels of leisure-time physical activity (LTPA) in adulthood. From sport activity participation reported by 17-year-old twins, we formed five groups: 1, 2, 3, 4, and 5+ different sport activities. At follow-up in their mid-thirties, twins were divided into four activity classes based on LTPA, including active commuting. Multinomial regression analyses, adjusted for several confounders, were conducted separately for male (N=1288) and female (N=1770) participants. Further, conditional logistic regression analysis included 23 twin pairs discordant for both diversity of sport activities in adolescence and LTPA in adulthood. The diversity of leisure-time sport activities in adolescence had a significant positive association with adulthood LTPA among females. Membership in the most active adult quartile, compared to the least active quartile, was predicted by participation in 2, 3, 4, and 5+ sport activities in adolescence with odds ratios: 1.52 (P=.11), 1.86 (P=.02), 1.29 (P=.39), and 3.12 (P=5.4e-05), respectively. Within-pair analyses, limited by the small sample of twins discordant for both adolescent activities and adult outcomes, did not replicate the association. A greater diversity of leisure-time sport activities in adolescence predicts higher levels of LTPA in adulthood in females, but the causal nature of this association remains unresolved. © 2017 John Wiley & Sons A/S.

    Bees and other pollinating insects are the important parts of biodiversity due to their great role in plant reproduction and crop production. To explore the role of city garden in native bees conservation, activity patterns, visiting behaviors and flowering plants with nectar or pollen were recorded in south Sichuan in winter. The results showed that, worker bees (Apis cerana cerana) were active to collect food out hive under suitable weather conditions, the duration of working was long. Peaks of the number of outgoing, entrance and foragers without pollen appeared at 14:00-15:00, and bimodal patterns were observed. While, peak of bees with pollen appeared at 11:00, and a unimodal pattern was observed. Time significantly affected the activity of workers. The workload of honey bees on nectar and pollen collection were different, just less than twenty percent foragers carrying pollen. Temperature and humidity also affected flights of bees to some degree, and bee activities showed similar patterns on different days. However, the activities had diverse characteristics in some time. Though a less number of plants were in flowering, most of them could be utilized by A. cerana cerana, and colonies could effectively get the food resource by behavior adjustment. In addition, visiting activities of bees on the flowers of main garden plants, such as Camellia japonica, showed obvious rhythm. Increasing the flowering plants with nectar and pollen in winter by scientific management of urban gardens would facilitate the creation of suitable habitats for A. cerana cerana and maintaining the wild population.

    To compare the associations between weight status and different forms of physical activity among adolescents. We conducted telephone surveys with 1718 New Hampshire and Vermont high school students and their parents as part of a longitudinal study of adolescent health. We surveyed adolescents about their team sports participation, other extracurricular physical activity, active commuting, physical education, recreational activity for fun, screen time, diet quality, and demographics. Overweight/obesity (BMI for age ≥ 85th percentile) and obesity (BMI for age ≥ 95 percentile) were based on self-reported height and weight. Overall, 29.0% (n = 498) of the sample was overweight/obese and 13.0% (n = 223) were obese. After adjustments, sports team participation was inversely related to overweight/obesity (relative risk [RR] = 0.73 [95% confidence interval (CI): 0.61, 0.87] for >2 sports teams versus 0) and obesity (RR = 0.61 [95% CI: 0.45, 0.81] for >2 sports teams versus 0). Additionally, active commuting to school was inversely related to obesity (RR = 0.67 [95% CI: 0.45, 0.99] for >3.5 days per week versus 0). Attributable risk estimates suggest obesity prevalence would decrease by 26.1% (95% CI: 9.4%, 42.8%) if all adolescents played on 2 sports teams per year and by 22.1% (95% CI: 0.1%, 43.3%) if all adolescents walked/biked to school at least 4 days per week. Team sport participation had the strongest and most consistent inverse association with weight status. Active commuting to school may reduce the risk of obesity, but not necessarily overweight, and should be studied further. Obesity prevention programs should consider strategies to increase team sport participation among all students.

    Television (TV) viewing has been associated with obesity although the effects of specific TV content on health and other behaviours remains unknown. We examined the association between watching sport on TV, physical activity levels, and risk of obesity. We studied 6,733 (aged 64.9 ± 9.2 yrs) men and women from the English Longitudinal Study of Ageing, a prospective study of community dwelling older adults. Data were collected on self reported TV time and content, and physical activity. Nurses measured height and weight for the calculation of body mass index. On average, participants reported viewing TV for 5.3 ± 4.1 hours per day and 30.3% of the sample watched sport on TV at least twice a week. There was no association between watching sport and physical activity levels. Participants that watched sports every day were at higher risk of obesity [odds ratio = 1.39, 95% CI, 1.15, 1.68) after adjustment for age, sex, smoking, alcohol, physical activity, total TV time, disability, and self-rated health. Watching elite athletes may have no role in the promotion of physical activity in older adults, which has implications for staging large sporting events with physical activity legacy promises.

    Physical activity has been associated with widespread anatomical and functional brain changes that occur following acute exercise or, in the case of athletes, throughout life. High levels of physical activity through the practice of sports also lead to better general health and increased cognitive function. Athletes are at risk, however, of suffering a concussion, the effects of which have been extensively described for brain function and anatomy. The level to which these effects are modulated by increased levels of fitness is not known. Here, we review literature describing the effects of physical activity and sports concussions on white matter, grey matter, neurochemistry and cortical excitability. We suggest that the effects of sports concussion can be coufounded by the effects of exercise. Indeed, available data show that the brain of athletes is different from that of healthy individuals with a non-active lifestyle. As a result, sports concussions take place in a context where structural/functional plasticity has occurred prior to the concussive event. The sports concussion literature does not permit, at present, to separate the effects of intense and repeated physical activity, and the abrupt removal from such activities, from those of concussion on brain structure and function.

    Full Text Available The objective of this work was to evaluate the free flavonoid content and antioxidant activity of winter wheat white flour, whole grain flour and bran in ecological and integrated farming system in the years 2009-2010. The experiment was established on a scientific research base Dolná Malanta in western Slovakia during the years 2009 and 2010. Content of free flavonoids and antioxidant activity of white flour and whole grain flour was not affected by farming systems. Antioxidant activity of whole grain flour was more effected by a year and by a forecrop. White flour contain two times less free flavonoids and antioxidant activity than whole grain flour. By milling process most of the free flavonoids and other compounds with higher antioxidant activity remain in outer layers of grain.

    Full Text Available This paper investigates the antioxidant activity of fermented milk products obtained by kombucha fermentation. Two starter cultures were used as follows: starter obtained after kombucha fermentation on sweetened stinging nettle extract; as well as starter obtained after kombucha fermentation on sweetened winter savory extract. The starters were added to milk with 0.8, 1.6 and 2.8% milk fat. Fermentation was carried out at 37, 40 and 43oC and stopped when the pH reached 4.5. Antioxidant activity to hydroxyl and DPPH radicals was monitored using response surface methodology. Kombucha fermented milk products with stinging nettle (KSN and with winter savory (KWS showed the same antioxidant response to hydroxyl and different response to DPPH radicals. Synergetic effect of milk fat and fermentation temperature to antioxidant activity to hydroxyl radicals for both types of kombucha fermented milk products (KSN and KWS was established. Optimum processing conditions in term of antioxidant activity are: milk fat around 2.8% and process temperature around 41 and 43°C for KSN and KWS respectively.

    To examine cross-sectional and longitudinal associations between socioeconomic status (SES), gender, sports participation and moderate-to-vigorous physical activity (MVPA) in adolescents. Project EAT (Eating Among Teens), a population-based longitudinal study followed a socioeconomically and ethnically diverse sample of 1709 adolescents in 1998-1999 (Time 1) and 2003-2004 (Time 2). Mixed model regression analyses were used to examine longitudinal trends in MVPA as a function of SES and previous sports involvement. For both genders, participation in organized sports and weekly hours of MVPA were positively associated with SES. On average, MVPA decreased between high school and young adulthood for both genders. Adolescents who participated in sports during high school showed a steeper decline in weekly hours of MVPA than their non-sports-participating counterparts. SES had a significant moderating effect on the change in MVPA over time for boys who participated in organized sports, with low SES boys showing a steeper decline in MVPA between time periods than higher SES boys. Although on average, a statistically significant difference in MVPA between previous sports participants and nonparticipants remained at Time 2, for all SES groups and both genders, the gap between hours of MVPA was either overcome or significantly narrowed by young adulthood. Increased dependence on organized sports for MVPA may be insufficient to meet the needs of youth following high school, especially for low SES youth. Designing physical activity promotions that reach and address the unique needs of lower SES youth and families is a public health priority.

    The purpose of this study was to investigate whether Danish children from immigrant backgrounds are less physically active than children from the ethnic majority, and to investigate the possible reasons for any differences found. Accelerometer measures of physical activity as well as questionnaire data about organised sports, family demography, resources and values were collected from 594 children of whom 67 had other ethnic background than Danish. Data were collected when the children were 6-7 years old and again later when the children were 9-10 years old. It was found that children from immigrant backgrounds were not less physically active than other children when their amounts of daily physical activity were measured by direct objective measures, despite their participation rate in organised sports being much lower. Using multiple logistic regression modelling, this study showed that lack of parental experience with organised sports and lack of economic/material resources explained much of the difference in sports participation. Children of immigrant background had significant lower participation in club sports but this did not affect their overall physical activity level.

    This study reports the positive physical, emotional and psychosocial changes induced by sport activity in a Paralympic swimmer with Charcot-Marie-Tooth (CMT) type 4A. When we compared evaluations before initiating sport activity with those after five years of competitive activity, we found: i) increased proximal muscles strength of upper limbs; ii) augmented ability to propel wheelchair independently; iii) improved quality of life; iv) reduced trait anxiety and striking improvement of depression; v) enhanced self-esteem. Longitudinal studies in large cohorts to evaluate the positive effects of sport activity are needed to support provision of evidence-based advice to patients and families.

    We investigated knee functions and a return to sports in 50 competitive athlete patients treated with arthroscopic anterior cruciate ligament reconstruction using double-looped STG augmented by woven polyester at a 1-year follow-up. There were 25 males and 25 females with a mean age of 24.3 years (range: 19-39 years). The majority of preinjury sports were basketball, volleyball and soccer. Athletic rehabilitation including agility training and sports-specific training was started at 12 weeks. Fourty patients (80%) was rated as normal or nearly normal on the assessment of International Knee Documentation Commitee postoperatively. Fourty-eight patients (96%) obtained full range of motion, and the mean quadriceps muscle strength of the injured side was 91.3%of that of the uninjured side. As for a return to sports, 46 patients (92%) were able to do fully competitive sports at a mean of 8.1 postoperative months. These results suggest that arthroscopic reconstruction using augmented double-looped STG allows early athletic rehabilitation, and lead satisfactory outcome as well as a reliable and early return to preinjury level of sport activity for the majority of the competitive athlete patients.

    Exercise is an important therapeutic tool in the management of diabetes in older people. Aim of this study was to assess the relationship among type II diabetes, sport, overweight, and symptomatic Achilles tendinopathy in elderly subjects. Thirty-eight patients suffering from Achilles tendinopathy and thirty-eight controls were enrolled. The prevalence of diabetes and sport practice as well as BMI and Glycated Hemoglobin (HbA1c) values were registered. An ultrasound evaluation of Achilles tendon was performed. Patients showed an increased prevalence of diabetes (42 vs. 13.1 %, p = 0.004), and practice of sport (60.5 vs. 28.9 %, p = 0.0001), and higher BMI values (26.8 ± 3 vs. 24.8 ± 2.3, p = 0.001). Sonographic abnormalities, being diagnostic criteria, were present in all the patients with Achilles tendinopathy, but signs of degeneration were also found in 36.8 % of asymptomatic controls. Symptomatic subjects with diabetes, compared to those without, showed a higher prevalence of severe degeneration (75 vs. 36.3 %, p = 0.01). HbA1c values were significantly lower in sport practitioners, both diabetics and non-diabetics. Moreover, patients practicing sport showed a trend towards lower BMI values, compared to the sedentary counterpart. Sport practice in elderly diabetics provides relevant metabolic advantages, reducing HbA1c and BMI. However, some sport activities (e.g., speed walking, jogging or tennis) can expose to the risk of Achilles tendinopathy. So, sport practice should be encouraged, but practitioners should follow individual training programs and be submitted to periodic sonographic controls.

  6. Organized Sports and Unstructured Active Play as Physical Activity Sources in Children From Low-Income, Chicago Households.

    2016-08-01

    This study tested associations of organized sports participation and unstructured active play with overall moderate and vigorous physical activity (MVPA) in low-income children and examined factors associated with participation frequency. Research staff visited 88 low-income Chicago households with children ages 6-13 years. MVPA was assessed through 7-day accelerometry. Researchers documented the home availability of physical activity equipment. Caregivers reported on child participation in organized sports and unstructured active play, family support for physical activity, perceived neighborhood safety, and access to neighborhood physical activity venues. Despite similar participation in organized sports and unstructured active play, boys accumulated more MVPA than girls. MVPA was predicted by an interaction between gender and unstructured active play. Boys accumulated 23-45 additional minutes of weekday MVPA and 53-62 additional minutes of weekend MVPA through unstructured active play, with no such associations in girls. Higher reported neighborhood safety and family support for physical activity were associated with engagement in unstructured active play for both genders, and with participation in organized sports for girls. Physical activity interventions for low-income, urban children should emphasize unstructured active play, particularly in boys. Fostering family support for physical activity and safe play environments may be critical intervention components.

    Abstract Physical activity has multiple health benefits but may also increase the risk of developing musculoskeletal pain (MSP). However, the relationship between physical activity and MSP has not been well characterized. This study examined the dose–response relationship between sports activity and MSP among adolescents. Two school-based serial surveys were conducted 1 year apart in adolescents aged 12 to 18 years in Unnan, Japan. Self-administered questionnaires were completed by 2403 students. Associations between time spent in organized sports activity and MSP were analyzed cross-sectionally (n = 2403) and longitudinally (n = 374, students free of pain and in seventh or 10th grade at baseline) with repeated-measures Poisson regression and restricted cubic splines, with adjustment for potential confounders. The prevalence of overall pain, defined as having pain recently at least several times a week in at least one part of the body, was 27.4%. In the cross-sectional analysis, sports activity was significantly associated with pain prevalence. Each additional 1 h/wk of sports activity was associated with a 3% higher probability of having pain (prevalence ratio = 1.03, 95% confidence interval = 1.02-1.04). Similar trends were found across causes (traumatic and nontraumatic pain) and anatomic locations (upper limbs, lower back, and lower limbs). In longitudinal analysis, the risk ratio for developing pain at 1-year follow-up per 1 h/wk increase in baseline sports activity was 1.03 (95% confidence interval = 1.02-1.05). Spline models indicated a linear association (P sports, the more likely they were to have and develop pain. PMID:26894915

    To determine whether adolescent attitudes towards sports, exercise, and fitness predict moderate-to-vigorous physical activity 5 and 10 years later. A diverse group of 1902 adolescents participating in Project Eating and Activity in Teens, reported weekly moderate-to-vigorous physical activity and attitudes toward sports, exercise, and fitness in Eating and Activity in Teens-I (1998-99), Eating and Activity in Teens-II (2003-04), and Eating and Activity in Teens-III (2008-09). Mean moderate-to-vigorous physical activity was 6.4, 5.1, and 4.0 hours/week at baseline, 5-year, and 10-year follow-up, respectively. Attitudes toward sports, exercise, and fitness together predicted moderate-to-vigorous physical activity at 5 and 10 years. Among the predictors of 5- and 10-year moderate-to-vigorous physical activity, attitude's effect size, though modest, was comparable to the effect sizes for sports participation and body mass index. Adolescents with more-favorable attitudes toward sports, exercise, and fitness engaged in approximately 30%-40% more weekly moderate-to-vigorous physical activity at follow-up (2.1 hour/week at 5 years and 1.2 hour/week at 10 years) than those with less-favorable attitudes. Adolescents' exercise-related attitudes predict subsequent moderate-to-vigorous physical activity independent of baseline behavior suggesting that youth moderate-to-vigorous physical activity promotion efforts may provide long-term benefits by helping youth develop favorable exercise attitudes.

    The purpose of this study was to provide comprehensive long-term data about sports activity levels in patients following total knee arthroplasty (TKA) and to determine the impact of pre-operative function, pain and specific performed sports on the results. 236 patients who have undergone TKA for severe osteoarthritis of the knee were asked to provide specific information regarding exercised types of sports before surgery and after at least 10 years following TKA. Pre- and postoperative function and pain were evaluated by the use of Tegner-, WOMAC- and VAS Score. After a mean of 14.9 years, a significant improvement regarding pain and function was observed. Pre-operative Tegner- and WOMAC scores revealed significant positive correlations with the post-operative Tegner-Score. Accordingly, a high percentage of patients (70.9%) stayed actively involved in sports. Nevertheless, the number of performing patients has decreased according to the sports impact. 71.3% continued practising low-impact-, 43.7% intermediate-impact sports whereas only 16.4% kept performing high impact sports. We conclude that TKA is highly effective in long-time pain reduction as well as improvement of function. Additionally, we found considerable sports activities preserved in the investigated series. However, sports activities in particular, seem to decrease according to the impact of sports.

    In outdoor activities, it seems reasonable that the longer children spend in spontaneous physical activity (PA), the higher the probability of being active. Indeed, the time spent outdoor has been identified as a variable consistently associated with the children's PA. Outdoor playing, such as the organized sports practice, appears associated with healthier lifestyle standards. All the recommendations mention the importance of increasing daily PA practice in children and teenagers, but few studies highlight the relationship between outdoor play and the recommended PA levels. The purpose of this study is to investigate the relationships between the frequency of outdoor play, the frequency of the organized sports practice, and the compliance of the recommendations for PA practice in children in the inner city area of Porto. The sample of this study is composed of 422 individuals (mean age of 11.6 years). Two hundred and twenty-five of them were girls and 197 were boys from the sixth grade (elementary schools located in the inner city area of Porto). PA was objectively evaluated using accelerometers. Participants reported frequency of participation in different PA contexts, such as sports practice and outdoor play. The results show a predictor effect of participating in sports three or more times per week on compliance of PA guidelines. In conclusion, organized sports practice seems more effective than outdoor play to reach the recommended levels of PA in children.

    Background: Physical activity (PA) in adolescence with long term illnesses or disabilities (LTID) is a public health concern. One way of increasing PA is through participation in sports clubs. Since sports clubs are organised and regular, there are expected to be differences in motivation for physical activity between adolescents that are members and non-members. The purpose of this study is to assess the impact of psychosocial factors on sports club membership and daily PA. Methods: ...

    Adult physical activity scales are used with children but may not be valid in this population. This study assesses the appropriateness and comprehensibility of currently used physical activity scales in children, identifies sources of response errors, and suggests scale modifications. Cognitive interviews were conducted with 30 children who had a lower extremity injury, purposefully sampled based on age and sex. Interviews were conducted to identify children's comprehension of 6 physical activity questionnaires: Tegner activity scale, Cincinnati Knee Rating System, KOOS-Child, Marx activity scale, HSS Pedi-FABS, and KOS sports activity scale. The Tegner scale uses complex activity level descriptions (eg, competitive vs. recreational sports, types of sports and inclusion of work-related physical activity). Activity frequency, description of movement, and sport type in the Cincinnati Knee Rating System led to response mapping issues in many children. Most children felt the KOOS-Child pictures depicting activities were helpful, but not all found the 7-day timeframe relevant. Whereas, most children found the Marx scale and HSS Pedi-FABS items clear, concise, and easy to answer. Children reported difficulties differentiating between endurance and duration items used in the HSS Pedi-FABS. The consistent response format of the KOS sports activity scale was considered a positive attribute although children had trouble comprehending terms such as grating and grinding. Children found some scales too difficult to answer, whereas others required modifications, particularly in general instruction, language, question format, and mapping (matching an answer to potential options) to adapt to the specific needs of children.

    Full Text Available ABSTRACTInjuries to the knee, including intra-articular fractures, ligamentous ruptures, and meniscal and articular cartilage lesions, are commonplace within sports. Despite advancements in surgical techniques and enhanced rehabilitation, athletes returning to cutting, pivoting, and jumping sports after a knee injury are at greater risk of sustaining a second injury. The clinical utility of objective criteria presents a decision-making challenge to ensure athletes are fully rehabilitated and safe to return to sport. A system centered on specific indicators that can be used to develop a comprehensive profile to monitor rehabilitation progression and to establish return to activity criteria is recommended to clear athletes to begin a progressive and systematic approach to activities and sports. Integration of a sports knee injury performance profile with return to activity criteria can guide clinicians in facilitating an athlete's safe return to sport, prevention of subsequent injury, and life-long knee joint health.

    The last few decades have seen substantial growth in the populations of competitive athletes and highly active people (CAHAP). Although vigorous physical exercise is an effective way to reduce the risk of cardiovascular (CV) disease, CAHAP remain susceptible to inherited and acquired CV disease, and may be most at risk for adverse CV outcomes during intense physical activity. Traditionally, multidisciplinary teams comprising athletic trainers, physical therapists, primary care sports medicine physicians, and orthopedic surgeons have provided clinical care for CAHAP. However, there is increasing recognition that a care team including qualified CV specialists optimizes care delivery for CAHAP. In recognition of the increasing demand for CV specialists competent in the care of CAHAP, the American College of Cardiology has recently established a Sports and Exercise Council. An important primary objective of this council is to define the essential skills necessary to practice effective sports cardiology. Copyright © 2017. Published by Elsevier Inc.

  4. Injuries associated with combat sports, active component, U.S. Armed Forces, 2010-2013.

    Science.gov (United States)

    2014-05-01

    The practice of combat sports creates a potential for training- and sports-related injuries among military members. During the 4-year surveillance period, there were 12,108 cases of injuries associated with combat sports among active component service members; the overall incidence rate was 21.0 per 10,000 person-years (p-yrs). The rates were higher among service members who were male, Hispanic, in the youngest age groups, in the Army, junior enlisted, and in combat-specific occupations. The rate among recruit/ trainees (779.4 per 10,000 p-yrs) was more than 165 times the rate among all other active component service members (non-recruits) (4.7 per 10,000 p-yrs). Sprains, strains, and contusions accounted for more than one-half of the primary (first-listed) diagnoses associated with combat sports cases. More serious conditions such as concussions/head injuries and skull/face fractures/intracranial injuries were reported among 3.9% and 2.1% of all cases and were more common among boxing-related cases. Hand/wrist fractures were also common among boxing cases. Wrestling had comparatively greater proportions of dislocations and open wounds. Although the combat sport training provides many physical and mental benefits to the individual, safety practices should be enforced to reduce the most frequent and serious injuries.

    Moderate to Vigorous Physical Activity (MVPA), including sport participation, is an important component of a healthy lifestyle. Scholars have devoted considerable attention to understanding the impact of parenthood on MVPA, albeit only for women. As the impact of fatherhood on men's lives is drawing more and more scholarly and societal attention, the aim of the current article is to provide an systematic overview of studies examining the impact of fatherhood on MVPA. A systematic review was conducted in Google Scholar, Web of Science and Web of Knowledge, using (combinations of) the search terms: father(hood), parent(hood), exercise, physical activity, sport and leisure time. This resulted in 54 papers reporting differences in MVPA and/or sport between fathers and childless men or within men that became father, of which 13 were included. Our overview of findings suggested that fathers spent less time on MVPA compared with childless men, but that fathers did not differ from their childless counterparts on the subarea of sport participation. Differences in time spent on MVPA were strongest between childless men and fathers with young children (< 6 yrs). Our systematic review revealed that fathers spent less time on MVPA compared to childless men, especially when they had young children. Interestingly, linkages between parental status and the subarea of sport participation were not found, which suggests that fathers cut back on other areas of MVPA. Given the impact of MVPA on a healthy lifestyle, future research in this field is warranted.

    Full Text Available The goal of this research is to determine whether the importance granted by friends to physical-sport activities influences adolescents’ dropout of physical-sport.A methodological triangulation was conducted, using quantitative and qualitative techniques. In the quantitative technique. the final sample comprised 1978 subjects, 51.7% girls and 48.3% boys. Descriptive analysis, inferential analysis (Cramer’s V, and multinomial regression analysis were performed on the data collected with the questionnaire.In the qualitative technique, four focus groups (n = 41were employed: parents, Physical Education teachers, teachers from other areas, and adolsescents. Results show that girls’ dropout rate is three times higher than that of the boys, and they are four times more likely to abandon this lifestyle than boys.The peer group is one of the most powerful informal education agents to influence adolescents’ physical-sport practice, but its influence varies by sex. If friends grant much, some, or very much importance to physical-sport practice, girls are less likely to drop out of such practice, but when boys’ friends grant no importance to physical-sport activity, they are five times more likely to drop out.

    Sports and energy drinks are being increasingly consumed and contain large amounts of sugars, which are known to increase Streptococcus mutans biofilm formation and metabolic activity. The purpose of this in vitro study was to investigate the effects of sports and energy drinks on S. mutans biofilm formation and metabolic activity. S. mutans UA159 was cultured with and without a dilution (1:3 ratio) of a variety of sports and energy drinks in bacterial media for 24 hours. The biofilm was washed, fixed, and stained. Biofilm growth was evaluated by reading absorbance of the crystal violet. Biofilm metabolic activity was measured by the biofilm-reducing XTT to a water-soluble orange compound. Gatorade Protein Recovery Shake and Starbucks Doubleshot Espresso Energy were found to significantly increase biofilm (30-fold and 22-fold, respectively) and metabolic activity (2-fold and 3-fold, respectively). However, most of the remaining drinks significantly inhibited biofilm growth and metabolic activity. Several sports and energy drinks, with sugars or sugar substitutes as their main ingredients inhibited S. mutans biofilm formation. Among the drinks evaluated, Gatorade Protein Recovery Chocolate Shake and Starbucks Doubleshot Energy appear to have cariogenic potential since they increased the biofilm formation and metabolic activity of S. mutans.

  10. Increasing late winter-early spring fire activity in Northern Spain: climate change or human footprint?

    Most of the fire activity across Spain concentrates during the summer months, but a secondary peak appears also during late winter and early spring (February and March). This peak represents a tiny fraction of the burned surface but in northern Spain becomes the main fire season, representing up to 60 % of the total burned surface. Moreover, the impact of this "unseasonal" fire regime is becoming more relevant; an analysis of the temporal evolution of the burned surface since 2005 shows that the suppression efforts of summer forest fires have apparently succeeded, while the opposite has occurred with late winter-early spring forest fires. For example, during March 2012 more than 22,000 ha were burned in the Spanish provinces of Asturias and Cantabria, while about 14,000 suffers the effects of fires in Northern Portugal. Anthropogenic factor (mostly linked to an extensive cattle farming in the mountains) are the main cause of such fire activity, but atmospheric factors also play a relevant role in the spread of this fires. Consequently, the main aim of this poster is to explore if the recent evolution of forest fires in the study area are consequence of an aggravation of the atmospheric conditions driving to more fire risk conditions, or other factor could also explain the increase in fire activity. Burned surface data obtained from official statistics since 1971 were compared with atmospheric data at two temporal scales: daily fire risk values calculated from synoptic records and long term drought indices (SPI and SPEI). The results show a long term increase in both daily fire risk and drought conditions, but this trend can be related to the background warming of the area, rather to an increase in the frequency and magnitude of the extreme fire weather events. Thus, we consider that the regional atmospheric evolution cannot explain by itself the recent increase in late winter-early spring fire activity. Additional anthropogenic factors, such as recent changes in

    To determine the frequency of sports physical activity in the urban population of Peru and to identify the sociodemographic, economic, and environmental factors associated with that activity. This study utilized information collected by the country's National Household Survey (Encuesta Nacional de Hogares) in the second quarter of 1997. That Survey is overseen by Peru's National Institute of Statistics and Informatics (Instituto Nacional de Estadística e Informática). The Survey was based on a probabilistic, multistage sample that was stratified for all the urban areas of the country, which was divided into eight geographic regions: metropolitan Lima, northern coast, central coast, southern coast, northern mountains, central mountains, southern mountains, and jungle. In total, 14 913 homes were visited and 45 319 people at least 15 years of age were interviewed. The frequency of engaging in sports physical activity was classified as daily, every other day, weekly, or occasional. "Regular sports activity" (RSA) was defined as engaging in sports either every day or every other day. The preferences for and obstacles to sports practice were also examined. A descriptive analysis of the levels of RSA was carried out for gender, using the chi-square test. The factors associated with RSA were analyzed through conditional multiple logistic regression and analysis of residuals, multicollinearity, and interactions. The level of significance was set at P jungle (15.3%), central mountains (12.8%), and central coast (12.1%). RSA was least common in two regions: southern mountains (9.7%) and metropolitan Lima (10.6%). The income bracket was not associated with RSA. However, other variables associated indirectly with the socioeconomic level - such as having more formal education, being employed, and having access to the Internet or cable television - and consumption of sports information were significantly and directly associated with RSA.

    2007-01-01

    Ankylosing spondylitis is a chronic inflammatory rheumatic disease that primarily affects the sacroiliac joints and spine, although it may involve entheses, peripheral joints and extraarticular organs. Disease treatment is directed toward the suppression of the inflammatory process and the improvement of the musculoskeletal system function. There are several treatment modalities: education of the patient and members of the family, pharmacological treatment, physical therapy and, in some cases, surgical treatment. An important segment of various modalities of physical therapy belongs to kinesitherapy, sports and recreation whose duration and intensity largely depends not only on the actual functional impairments, but also on the presence of some other disease or contraindications. Kinesitherapy is directed toward maintenance and improvement of the function of the spine, thoracic cavity and large synovial joints as well as the prevention of deformities or contractures. Kinesitherapy and sports programmes may involve individual or group approach. Patients are encouraged to participate in sports activities that may imitate or substitute specific forms of exercises.

    Systematic review with meta-analysis. To identify risk factors for osteoarthritis (OA) of the knee, hip, and ankle, including joint injury, sport, physical activity, overweight/obesity, and occupational activity, in all age groups. OA is a significant health problem worldwide, affecting up to 10% of men and 18% of women over 60 years of age. There has not been a comprehensive review examining modifiable physical risk factors associated with the onset of OA. This evidence is important to inform the physiotherapy management of individuals following onset of OA. Twelve electronic databases were systematically reviewed. The studies selected met the following criteria: (1) original data; (2) joint injury, sport activity, physical activity, overweight/obesity, and/or occupational activity investigated as risk factors; (3) outcomes included OA (hip, knee, and/or ankle); and (4) analytic component of study design. The data extracted included study design, years of follow-up, study population, OA definition, risk factors, and results (effect estimates reported or calculated where available). The quality of evidence was assessed based on a modified version of the Downs and Black checklist. Joint injury, obesity, and occupational activity were associated with an increased risk of OA of the knee and hip. Sport and physical activity produced inconsistent findings. Joint injury was identified as a significant risk factor for knee OA (combined odds ratio = 3.8; 95% confidence interval: 2.0, 7.2) and hip OA (combined odds ratio = 5.0; 95% confidence interval: 1.4, 18.2), as was previous meniscectomy with or without anterior cruciate ligament injury for knee OA (combined odds ratio = 7.4; 95% confidence interval: 4.0, 13.7). There is a paucity of research examining risk factors associated with ankle OA; this review identified only 2 studies with this outcome. Joint injury, obesity, and occupational activity are associated with an increased risk of knee and hip OA. Some findings

    Full Text Available ICT cause and accelerate the processes of getting and developing knowledge, facilitate the process of modernization of education. Active video games, which involve physical movement of the player’s body, are used to increase the efficiency of perception of the educational material connected with motor activity and to raise the level of motor activity of young people Active video games which require the display of strength, coordination and flexibility are included into the curriculum of physical education, combining physical education with a game. These games use the player’s body movements as a controller, thus providing an alternative to static games and helping to preserve health. The study is the analysis of publications on the use of ICT, namely active video games (exergames in the field of physical culture and sports. The study has found that the use of active video games in educational and training process promotes physical qualities, improves cognitive functions, improves socialization and motivation to exercise. It has been proved that the use of exergames motivation increases motor activity of students and adults. Specially selected exergames help to familiarize students with various types of sports activities, such as those that are difficult to practice in the gym. Rational use of active video games in the classroom optimizes the educational process. Modern mobile exergames on one platform include several sports and can be used outside sports facilities, encouraging more people to exercise. Exergames personalize elements of the game, the level of difficulty, type of physical activity, have a system of evaluation of changes in the user’s preparedness, increase motivation to exercise.

    Multicultural scholarship in sport and exercise psychology should help us understand and apply cultural competencies for all to be physically active. In the present study, two Asian countries, Japan and Singapore, were chosen. The participation rate for physical activities among adolescent girls tends to be lower than that of boys in both countries. Thus, the purpose of the project was to gain knowledge and understanding about sociocultural factors that may explain adolescent girls' perceptions and behaviors toward sport, physical activity, and physical education (PE). A qualitative approach using semi-structured interviews with focus groups was used to understand meanings of physical activity among Buddhist Japanese, and Hindu Indians and Christian Chinese from Singapore. Each focus group consisted of four or five girls and female researchers. Based on the analysis, we created four themes which were "cultural identities," "Asian girls and sport/physical activities," "PE experiences," "motivation for future involvement." The Buddhist Japanese, Hindu Indian, and Christian Chinese participants each reported unique physical activity experiences, and all the participants were aware of how Asian culture may affect being physically active. Experiences of PE classes were similar but perceptions of their PE attire were different for Christian Chinese and Hindu Indian adolescent girls. Based on the results, the importance of nurturing cultural competencies and ways to encourage girls to be physically active throughout life were discussed.

    Glenohumeral translations have been mainly investigated during static poses while shoulder rehabilitation exercises, activities of daily living, and sports activities are dynamic. Our objective was to assess glenohumeral translations during shoulder rehabilitation exercises, activities of daily living, and sports activities to provide a preliminary analysis of glenohumeral arthrokinematics in a broad range of dynamic tasks. Glenohumeral translations were computed from trajectories of markers fitted to intracortical pins inserted into the scapula and the humerus. Two participants (P1 and P2) performed full range-of-motion movements including maximum arm elevations and internal-external rotations rehabilitation exercises, six activities of daily living, and five sports activities. During range-of-motion movements, maximum upward translation was 7.5mm (P1) and 4.7mm (P2). Upward translation during elevations was smaller with the arm internally (3.6mm (P1) and 2.9mm (P2)) than neutrally (4.2mm (P1) and 3.7mm (P2)) and externally rotated (4.3mm (P1) and 4.3mm (P2)). For activities of daily living and sports activities, only anterior translation during reach axilla for P1 and upward translation during ball throwing for P2 were larger than the translation measured during range-of-motion movements (108% and 114%, respectively). While previous electromyography-based studies recommended external rotation during arm elevation to minimize upward translation, measures of glenohumeral translations suggest that internal rotation may be better. Similar amplitude of translation during ROM movement and sports activities suggests that large excursions of the humeral head may be caused not only by fast movements, but also by large amplitude movements.

    The next generation geostationary satellite, GOES-R, will carry two new instruments with unique atmospheric and surface observing capabilities, the Advanced Baseline Imager (ABI) and the Geostationary Lightning Mapper (GLM), to study short-term weather processes. The ABI will bring enhanced multispectral observing capabilities with frequent refresh rates for regional and full disk coverage to geostationary orbit to address many existing and new forecast challenges. The GLM will, for the first time, provide the continuous monitoring of total lightning flashes over a hemispherical region from space. NOAA established the GOES-R Proving Ground activity several years ago to demonstrate the new capabilities of these instruments and to prepare forecasters for their day one use. Proving Ground partners work closely with algorithm developers and the end user community to develop and transition proxy data sets representing GOES-R observing capabilities. This close collaboration helps to maximize refine algorithms leading to the delivery of a product that effectively address a forecast challenge. The NASA Short-term Prediction Research and Transition (SPoRT) program has been a participant in the NOAA GOES-R Proving Ground activity by developing and disseminating selected GOES-R proxy products to collaborating WFOs and National Centers. Established in 2002 to demonstrate the weather and forecasting application of real-time EOS measurements, the SPoRT program has grown to be an end-to-end research to operations activity focused on the use of advanced NASA modeling and data assimilation approaches, nowcasting techniques, and unique high-resolution multispectral data from EOS satellites to improve short-term weather forecasts on a regional and local scale. Participation in the Proving Ground activities extends SPoRT s activities and taps its experience and expertise in diagnostic weather analysis, short-term weather forecasting, and the transition of research and experimental

    Physical activity is important for youth with inflammatory bowel diseases (IBD), and sports participation is a common way in which youth are physically active. Yet, studies examining sports participation in youth with IBD and barriers to sports participation are lacking. This study examined the role of disease complications, body mass index (BMI), subjective physical health, and psychosocial functioning in influencing sports participation in a large sample of youth with IBD participating in the Crohn's and Colitis Foundation of America Partners (CCFA Partners) Kids and Teens Registry. CCFA Partners Kids and Teens is an internet-based cohort study in which participants and their parents self-report demographics, disease characteristics, anthropometrics, and validated assessments of physical health, psychosocial functioning, and perceived impairment in sports participation. We performed a cross-sectional analysis of 450 cohort participants, age 12-17 years. Nearly two-thirds of the sample reported that their IBD resulted in some impairment in sports participation. IBD disease activity was associated with perceived impairment in sports participation. In a forward regression analysis controlling for disease activity, fatigue, pain, and past IBD-related surgery emerged as the most salient correlates of impairment in sports participation. Disease activity and subjective physical health symptoms were the most salient correlates of impairment in sports participation. Whether these barriers interfere with physical activity more generally deserves further study, as does replication of these findings longitudinally. Ultimately, a greater understanding of potential barriers to sports participation may be useful for generating targeted physical activity recommendations for youth with IBD.

    2015-10-01

    Physical activity and exercise is the mainstay of chronic disease prevention and health maintenance for all people with and without a disability, and clear evidence exists of the benefits among various populations with neurologic disabilities. However, the potential benefits of organized sports for people with neurologic disabilities are not as well explored. In this narrative review, current evidence regarding the impact of organized sports on activity, participation, and quality of life in people with neurologic disabilities of all ages is summarized, and facilitators of and barriers to participation in sports for this population are discussed. The articles reviewed were divided into 2 sets: (1) children and adolescents and (2) adults. The subjects of almost all of the studies were persons with a spinal cord injury. Children and adolescents with a disability who engaged in sports reported self-concept scores close to those of able-bodied athletes, as well as higher levels of physical activity. Adults with a spinal cord injury who engaged in organized sports reported decreased depression and anxiety, increased life satisfaction, and increased opportunity for gainful employment compared with nonathletic persons with disabilities. General facilitators, regardless of age, were fitness, fun, health, competence, and social aspects, whereas overall barriers were lack of or inappropriate medical advice and facilities, decreased self-esteem, poor finances, dependency on others, and views held by others. The importance of this topic for further research is highlighted, and suggestions for future studies are proposed. Copyright © 2015 American Academy of Physical Medicine and Rehabilitation.

    Full Text Available Background As a conscious activity of an individual, physical activity (PA constitutes an element of the free-time dimension. The type of goal allows us to distinguish between sport and PA: sport performance vs. psychophysical health. Drawing on the theory of the motivational function of an objective, this study examined the motivational function of an objective in physical activity and sport. Participants and procedures The sample consisted of 2141 individuals: 1163 women aged 16-64 years (M = 23.90, SD = 8.30 and 978 men aged 16-66 years (M = 24.50, SD = 9.40 who completed the Inventory of Physical Activity Objectives (IPAO, which includes the following scales: 1 motivational value, 2 time management, 3 persistence in action, and 4 motivational conflict. There are also questions that allow one to control for variables such as the variety of forms, duration, and frequency of PA, and socio-demographic variables. Results Males presented different motives of physical activity than females. Motives related to shapely body and health were more important for females. The most important motives for males were physical fitness and shapely body. The gender of participants moderates the motivational value of the specific objectives of physical activity and persistence in action. Conclusions With knowledge about the purposefulness of actions, it is possible to support and shape additional motivation experienced by an individual, by setting new, realistic objectives.

    2010-09-01

    To examine the possible effects of physical activity, sports, and restrained eating on the relationship between overweight and absenteeism. Using a web-based lifestyle questionnaire, responses were obtained from 3030 employees in a large banking corporation. These data were then coupled with data from the company's absenteeism register. Physical activity and sports acted as moderator variables in that they both attenuated the positive relationship between overweight and/or obesity and absenteeism. Restrained eating also moderated the relationship between overweight and absenteeism. Remarkably, the degree of overweight was more strongly related to augmented absenteeism in people with higher levels of restrained eating. To reduce absenteeism in overweight employees, it may be beneficial to focus on stimulating physical activity and not on interventions aimed at promoting dieting (restrained eating).

The design was cross-sectional. A convenient sample of 869 sixth and seventh grade students (12-14 years) was invited to participate in the study. A total of 568 students fulfilled the inclusion criteria and comprised the final sample for this study. Mathematic performance was assessed by a customized test and inhibitory control was assessed by a modified Eriksen flanker task. Physical activity was assessed with GT3X and GT3X+ accelerometers presented in sex-specific quartiles of mean counts per minute and mean minutes per day in moderate-to-vigorous physical activity. Active commuting and sports participation was self-reported. Mixed model regression was applied. Total physical activity level was stratified by bicycling status in order to bypass measurement error subject to the accelerometer. Non-cyclists in the 2nd quartile of counts per minute displayed a higher mathematic score, so did cyclists in the 2nd and 3rd quartile of moderate-to-vigorous physical activity relative to the least active quartile. Non-cyclists in the 3rd quartile of counts per minute had an improved reaction time and cyclists in the 2nd quartile of counts per minute and moderate-to-vigorous physical activity displayed an improved accuracy, whereas non-cyclists in the 2nd quartile of counts per minute showed an inferior accuracy relative to the least active quartile. Bicycling to school and organized sports participation were positively associated with mathematic performance. Sports participation and bicycling were positively associated with mathematic performance. Results regarding objectively measured physical activity were mixed. Although, no linear nor dose-response relationship was observed there was no indication of a higher activity level impairing the scholastic or cognitive performance.

    Medial displacement calcaneal osteotomy with flexor digitorum longus transfer is a common treatment for the management of the adult flatfoot associated with posterior tibial tendon dysfunction. In the literature, there is a paucity of information regarding the ability of patients to return to sport and recreational activities after this surgical procedure. The purpose of this retrospective clinical study was to assess the rate and type of athletic activities that patients participated in before and after medial displacement calcaneal osteotomy with flexor digitorum longus transfer. A consecutive series of 42 patients with a mean age at surgery of 41 years (range 19-74 years) was evaluated with a minimum follow-up of 24 months (range 18-31 months). Pre- and post-operative sporting activities were assessed. At final follow-up, patients were asked to complete a Sports Athlete Foot and Ankle Score (SAFAS). Each patient was also evaluated with weight-bearing radiographs of the foot before surgery and at final follow-up. Preoperatively, 27 of 42 (64.3 %) patients were engaged in athletic activities, participating in an average of 1.4 h/week (range 0-6 h/week); post-operatively, 36/42 (85.7 %) participated in sport and recreational activities for an average of 3.5 h/week (range 0-15 h/week). Meary's angle improved significantly from 11.5 ± 6.2 degrees preoperatively to 7.0 ± 5.7 degrees at final follow-up (p < 0.01); calcaneal pitch improved significantly from 16.5 ± 4.6 degrees to 19.0 ± 5.0 degrees (p < 0.01). At final follow-up, patients demonstrated good SAFASs in symptom tolerance (86.4 %), pain tolerance (89.0 %), daily living performance (96.1 %), and sports performance (86.7 %). The majority of patients returned to sports and recreational activity after medial displacement calcaneal osteotomy and flexor digitorum longus for the treatment of adult flatfoot associated with posterior tibial tendon dysfunction.

    The relationship between sport participation and BMI in children and adolescents is unclear, with some studies showing no association at all and others suggesting that sport is linked to lower BMI. Another possibility, however, is that this relationship is bidirectional, with sport leading to lower BMI but BMI also influencing sport participation. Here, we examine the direction of this association by analyzing a longitudinal dataset. Data come from the Physical Health Activity Study Team (PHAST) study, a prospective open cohort study including 2278 children at baseline, followed from 2004 to 2010. We fit 3 lagged mixed effects models: One examining the simultaneous relationship, one regressing past BMI on present sport participation, and one regressing sport participation on present BMI. Our baseline sample included 1999 children, of whom 50% were female. Mean BMI increased over the study period from 19.0 (SD = 3.7) to 21.2 (SD = 4.1), while organized sport participation declined. Model results showed that BMI and sport are weakly associated, and that each of these variables predicts the other, which generally supports a bidirectional relationship. Consistent with some previous reports, however, the effect size in both directions is very small. At the levels of participation in our sample, activity and BMI are very weakly related. Findings should not obscure the other benefits of physical activity.

    Abstract Objectives Studying the quality of life of people with a spinal cord injury is of great importance as it allows the monitoring of both functioning and adaptation to disability. The aim of this study was to determine the difference between persons with a spinal cord injury involved in sports activities and those not involved in sports activities in relation to their quality of life and the presence of secondary health conditions (pressure ulcers, urinary infections, muscle spasms, osteoporosis, pain, kidney problems-infections, calculosis and poor circulation). Methods The study included a total of 44 participants with spinal cord injury-paraplegia of both genders; 26 of them were athletes and 18 were not athletes. The athletes were training actively for the last two years, minimally 2-3 times per week. A specially designed questionnaire, medical documentation and the Spinal Cord Injury Quality of Life Questionnaire (SCI QL-23) were used for research purposes. Chi-square test was used to analyze the differences between the groups, while multiple analysis of variance (MANOVA) was used to determine the differences between the sets of variables. Results Among the participants, the athletes perceived higher quality of life than the non-athletes (male gender psports activities significantly improves quality of life in the population of people with spinal cord injury-paraplegia. However, sports activities only partially affect secondary health conditions. PMID:27284378

    Established in 2002 to demonstrate the weather and forecasting application of real-time EOS measurements, the Short-term Prediction Research and Transition (SPoRT) program has grown to be an end-to-end research to operations activity focused on the use of advanced NASA modeling and data assimilation approaches, nowcasting techniques, and unique high-resolution multispectral observational data applications from EOS satellites to improve short-term weather forecasts on a regional and local scale. SPoRT currently partners with several universities and other government agencies for access to real-time data and products, and works collaboratively with them and operational end users at 13 WFOs to develop and test the new products and capabilities in a "test-bed" mode. The test-bed simulates key aspects of the operational environment without putting constraints on the forecaster workload. Products and capabilities which show utility in the test-bed environment are then transitioned experimentally into the operational environment for further evaluation and assessment. SPoRT focuses on a suite of data and products from MODIS, AMSR-E, and AIRS on the NASA Terra and Aqua satellites, and total lightning measurements from ground-based networks. Some of the observations are assimilated into or used with various versions of the WRF model to provide supplemental forecast guidance to operational end users. SPoRT is enhancing partnerships with NOAA / NESDIS for new product development and data access to exploit the remote sensing capabilities of instruments on the NPOESS satellites to address short term weather forecasting problems. The VIIRS and CrIS instruments on the NPP and follow-on NPOESS satellites provide similar observing capabilities to the MODIS and AIRS instruments on Terra and Aqua. SPoRT will be transitioning existing and new capabilities into the AWIIPS II environment to continue the continuity of its activities.

    While the positive effect of sports and exercise on physical and psychological well being is well documented within the general population, the effects of sports on the functional ability of a child with mental retardation are limited. To determine if sports activities have been detrimental in improving functional ability in sample of children with mental retardation based in Kolkata, a metropolis in India. Field level study. Six sports associations registered under the Sports Authority of India for training children with mental retardation were shortlisted on the basis of four criteria. From the register, every third name (gender irrespective) belonging to the second (12-15 years) and third (15-21 years) subclasses (out of the four categories laid down in the Special Olympics participation rules) against a constraint of at least two years active attendance in the sports facility for the child was selected. A sample of 31 children was drawn and the WHO Disability Assessment Schedule 2.0 (WHODAS 2.0) 12-item version was administered to the caregiver-teacher-coach team of the sample. Relative changes in scores between the point when the survey was conducted and the point when the child joined the sports facility was used as the dependent variable for regression analysis. The number of years in active sports, in school age of the respondent and base score of the children when they joined school were the independent variables. For seven of the WHODAS 2.0 12-item attributes, the number of years in sports activities was found to have a statistically significant effect (p mental retardation. The number of years in school was also another statistically significant factor (p sports activities was a significant factor responsible for improving the functioning of children with mild to moderate mental retardation.

    Anecdotal evidence suggests compression garments (CGs) are being worn underneath normal playing attire during team sports. Wearing CGs as a baselayer could possibly increase heat storage, and so this field study investigated the effects of wearing CGs, comprising knee-length shorts and short-sleeved top underneath normal match-day attire (COMP), versus normal match-day attire alone (NORM) on thermoregulation during simulated team sport activity. Ten match-fit field hockey players twice performed 4x15min exercise bouts consisting of repeated cycles of intermittent, varied-intensity 20m shuttle running (Loughborough intermittent shuttle test), once in COMP and once in NORM. Testing was conducted in an indoor gymnasium (ambient conditions: approximately 17 degrees C, approximately 60% relative humidity). Participants acted as their own controls. Heart rate (HR), 15m sprint time, ratings of perceived exertion (RPE), blood lactate concentration, sweat rate and body core temperature (T(core)) were similar between trials (p>0.05). Mean skin temperature (T(skin)) was significantly higher in COMP than NORM (pteam sport exercise in temperate ambient conditions had no thermoregulatory benefits nor any detrimental effects on T(core), physiological performance or dehydration. However, the higher T(skin) may affect individual preference for wearing CGs as an undergarment during team sports.

    Three systematic reviews were conducted on: (i) the history of mouthguard use in sports; (ii) mouthguard material and construction; and (iii) the effectiveness of mouthguards in preventing orofacial injuries and concussions. Retrieval databases and bibliographies were explored to find studies using specific key words for each topic. The first recorded use of mouthguards was by boxers, and in the 1920s professional boxing became the first sport to require mouthguards. Advocacy by the American Dental Association led to the mandating of mouthguards for US high school football in the 1962 season. Currently, the US National Collegiate Athletic Association requires mouthguards for four sports (ice hockey, lacrosse, field hockey and football). However, the American Dental Association recommends the use of mouthguards in 29 sports/exercise activities. Mouthguard properties measured in various studies included shock-absorbing capability, hardness, stiffness (indicative of protective capability), tensile strength, tear strength (indicative of durability) and water absorption. Materials used for mouthguards included: (i) polyvinylacetate-polyethylene or ethylene vinyl acetate (EVA) copolymer; (ii) polyvinylchloride; (iii) latex rubber; (iv) acrylic resin; and (v) polyurethane. Latex rubber was a popular material used in early mouthguards but it has lower shock absorbency, lower hardness and less tear and tensile strength than EVA or polyurethane. Among the more modern materials, none seems to stand out as superior to another since the characteristics of all the modern materials can be manipulated to provide a range of favourable characteristics. Impact studies have shown that compared with no mouthguard, mouthguards composed of many types of materials reduce the number of fractured teeth and head acceleration. In mouthguard design, consideration must be given to the nature of the collision (hard or soft objects) and characteristics of the mouth (e.g. brittle incisors, more

    Physical activity is one of the key determinants of physical, mental, and social health of children and adolescents. Therefore, the early development of health-relevant behavior patterns is of high relevance. To examine the impact of selected socioeconomic factors as well as media consumption, on sports activities and the motor skills of 10- to 14-year-old secondary school students. Body height and body weight were measured. The motor skills were determined with the Deutschen Motorik Test (DMT 6‑18; German Motor Test). Information about media use, media equipment, recreational sports activities, migration status, and the parents' profession was collected by means of a standardized questionnaire. A total of 391 adolescents have been tested (male 235; female 156). Body mass index (BMI) types are evenly distributed on gender. On a weekday, the pupils spend 10.3 h using media (SD ± 9.1 h). On weekends, media use increases up to 12 h per day on average (SD ± 9.7 h). The number of available media is independent from the age of the respondents and the social status of their families. According to bivariate correlations, heavy media use, a high BMI as well as migration status correlate negatively with both sports activities and motor skills. BMI seems to have the strongest influence on athletic performance (b = 0.41). Media use is an important determinant of juvenile sports activity and motor performance, being part of a complex juvenile leisure behavior.

    Issue addressed: Recently arrived migrants and refugees from a culturally and linguistically diverse background (CALD) may be particularly vulnerable to social exclusion. Participation in sport is endorsed as a vehicle to ease the resettlement process; however, in Australia, this is often thought as a simple matter of integration into existing sport structures (e.g. clubs). This approach fails to place actual community needs at the centre of sport engagement efforts. Methods: A consultation framework was established with South Australian CALD community leaders and organisations to scope needs for community-based alternatives to participation in traditional sport (e.g. clubs), co-design a suitable community sport program and pilot it in five communities. Interviews and questionnaire surveys were conducted with participants, community representatives, stakeholders and volunteers. Results: Regular, free soccer activities engaged 263 young people from a great variety of nationalities, including over 50% refugees, in secondary state school and community-based sites. Conclusion: Alternative community sport programs can provide a basic but valuable forum to promote physical activity and associated well being in CALD and refugee communities. So what?: Alternative approaches can extend the health benefits of sport participation to disadvantaged children and youth who are excluded from traditional sport participation opportunities.

    Yoshiya, Shinichi

    Exercise and sports activities can afford mechanical stimuli to the bone and joint tissues which are required to maintain the tissue properties. Moreover, physical exercise is an important part of the management of bone and joint morbidities such as osteoporosis, osteoarthritis, and low back pain. On the other hand, excessive mechanical load involved in exercise and sports activities can be harmful potentially causing overuse injuries of the musculoskeletal tissues. Especially, safety margin for the amount of acceptable mechanical stress is narrow in the elderly due to preexisting musculoskeletal problems. Preparticipation medical checkup and construction of appropriate exercise program based on the physical assessment are mandatory to prevent overload applied to the bone and joint tissues.

    This study aimed to examine the associations of birth weight with ability in school sports in adolescence and participation in leisure-time physical activity (LTPA) across adulthood and to investigate whether associations between birth weight and LTPA change with age. Study participants were British singletons born in 1946 and followed up to age 68 yr (the Medical Research Council National Survey of Health and Development). Birth weights were extracted from birth records. Teacher reports of ability in school sports were collected at age 13 yr. LTPA was self-reported at ages 36, 43, 53, 60-64, and 68 yr and categorized at each age as participating in sports, exercise, and other vigorous LTPA at least once per month versus no participation. Associations were examined using standard and mixed-effects logistic regression models. Relevant data were available for 2739 study participants (50.1% female). When compared with the low birth weight group (≤2.50 kg), those with heavier birth weights were more likely to be rated as above average or average at school sports (vs below average); fully adjusted odds ratio = 1.78 (95% confidence interval = 1.14-2.77). Across adulthood, those with heavier birth weights were more likely to participate in LTPA than those with low birth weight; fully adjusted odds ratio of LTPA across adulthood = 1.52 (95% confidence interval = 1.09-2.14). This association did not vary by age (P = 0.5 for birth weight by age interaction). Low birth weight was associated with lower ability in school sports and with nonparticipation in LTPA across adulthood. Identifying the underlying developmental and social processes operating across life for low birth weight infants may inform the design of appropriate interventions to support participation in LTPA across life.

    The purpose of this paper is to make clear the plural structures of femininity and of masculinity, and to investigate how sport activities influence the ways in which Japanese teenagers perceive gender, based on a questionnaire survey in junior high schools in Tokyo. By factor analysis of eight items of gender perceptions, these items were divided into three factors. Boys'gender perceptions consist of 'sturdiness', 'discontent with one's own sex', and 'male's superiority on intellectuality'. ...

    The activity of lecithin: cholesterol acyltransferase (LCAT) and the plasma lipoprotein concentrations of elite athletes from 8 selected sports (volleyball, judo, sprinting, wrestling, throwing, cycling, water polo and tennis) were determined and compared with those of a sedentary control group. Plasma LCAT activity levels in the athletes were significantly 2.2-7.0 times higher than in the controls in most sports (p less than 0.01). Judo, sprinting, wrestling and throwing had comparable LCAT values while tennis, volleyball and cycling were considerably higher. HDL-C concentration was significantly higher than controls in the water polo (p less than 0.05), cycling and volleyball (p less than 0.01) groups. Percentage lipoprotein distribution in the athletes in all sports except tennis, throwing and wrestling were similar to the controls. The differences among groups in LCAT activity may be related to the effect of physical exercise and training adaptations to lipid metabolism. This may be of importance when judging the benefit of exercise for atherosclerosis protection.

    Recreational or regular physical and sport activities may be responsible for a wide range of cutaneous complications. Among them, "sports purpura" is a peculiar symptom that can occur during a large number of sports. "Effort purpura" defines any purpura occurring within the context of physical exercise irrespective of its cause. Therefore this clinical diagnosis includes various aetiologies. Diagnosis of traumatic purpura is often easy if the sport is mentioned in the anamnesis; cutaneous exercise - induced vasculitis must be also noted. Purpura can reveal systemic diseases or internal haemorrhage, such as spleen rupture, thrombopathies or systemic vasculitis, and other effort purpuras must be taken into account, including those related to the environment (cold, sun exposure...). Knowledge of a physical activity before the occurrence of purpura should be known by practitioner to avoid unnecessary and costly explorations in most of the cases.

These technologies allow for the calculation of displacement, velocity and acceleration during a match or training session. The accurate quantification of these variables is critical so that meaningful changes in team-sport athlete external load can be detected. High-velocity running, including sprinting, may be important for specific team-sport match activities, including evading an opponent or creating a shot on goal.

    2014-05-01

    The settings approach to health promotion is a world-known concept concerning settings like city, hospital, school, and workplace. The concept has also been used in some regionally specific settings, such as island, prison, or university. However, there are still many, often noninstitutional, settings that have a lot of potential but have not yet been recognized. One of the newcomers is the youth sports club, which has the potential to reach a lot of children and adolescents and is effective, via its casual educational nature based on voluntary participation. According to research, health is an important aim for most youth sports clubs, but it has not been converted into practical actions. Indeed, the clubs often recognize the importance of healthy lifestyles, but there is a lack of understanding of what to do to reinforce it within one's activities. That is why, on the basis of the results of the Health Promoting Sports Club survey in Finland, guidelines for clubs to enhance health promotion as a part of their activities were created. The aim of this article is to present the guidelines, theirs rationale, and practical examples.

    The purpose of this study was to assess participation in sport and physical activity following open reduction and internal fixation of a Lisfranc injury in a cohort of recreational athletes. This study identified all adult patients aged 55 years or younger who presented with a Lisfranc injury and underwent open reduction and internal fixation (ORIF) using a Lisfranc screw combined with bridge plating technique. Sports and physical activity participation was assessed with a new sports-specific, patient-administered questionnaire. Clinical outcomes were assessed with the Foot and Ankle Outcome Score (FAOS). Thirty-three patients qualified for the study (21 men/12 women). Mean age and follow-up were 31.2 (range, 18-55) years and 2.9 (range, 1.5-5.4) years, respectively. Postoperatively, 31 patients (94%) were able to return to some form of sport. Twenty-two patients (66%) returned to playing sport at or above their preinjury level. Of the 11 patients who played less sport, 6 had ongoing pain, and the remaining 5 were asymptomatic but were participating less frequently because of other lifestyle reasons. In addition, of the 33 patients, 11 (33%) had some degree of ongoing pain that might limit their ability to return to sports and physical activities. There was strong correlation between overall FAOS and the Sports Questionnaire. Most patients who sustained a Lisfranc injury could return to sport and physical activity after ORIF. Patients should be counseled preoperatively that about 1 in 3 might experience continued pain at the injury site Level of Evidence: Level IV, retrospective case series.

    Since Saturn orbital insertion in July 2004, the Cassini orbiter has been observing Titan throughout most of the northern winter season (October 2002-August 2009) and the beginning of spring, allowing a detailed monitoring of Titan's cloud coverage at high spatial resolution with close flybys on a monthly basis. This study reports on the analysis of all the near-infrared images of Titan's clouds acquired by the Visual and Infrared Mapping Spectrometer (VIMS) during 67 targeted flybys of Titan between July 2004 and April 2010.The VIMS observations show numerous sporadic clouds at southern high and mid-latitudes, rare clouds in the equatorial region, and reveal a long-lived cloud cap above the north pole, ubiquitous poleward of 60??N. These observations allow us to follow the evolution of the cloud coverage during almost a 6-year period including the equinox, and greatly help to further constrain global circulation models (GCMs). After 4. years of regular outbursts observed by Cassini between 2004 and 2008, southern polar cloud activity started declining, and completely ceased 1. year before spring equinox. The extensive cloud system over the north pole, stable between 2004 and 2008, progressively fractionated and vanished as Titan entered into northern spring. At southern mid-latitudes, clouds were continuously observed throughout the VIMS observing period, even after equinox, in a latitude band between 30??S and 60??S. During the whole period of observation, only a dozen clouds were observed closer to the equator, though they were slightly more frequent as equinox approached. We also investigated the distribution of clouds with longitude. We found that southern polar clouds, before disappearing in mid-2008, were systematically concentrated in the leading hemisphere of Titan, in particular above and to the east of Ontario Lacus, the largest reservoir of hydrocarbons in the area. Clouds are also non-homogeneously distributed with longitude at southern mid

    Full Text Available ObjectiveTo investigate the effects of a school-based once-a-week sports program on physical fitness, physical activity, and cardiometabolic health in children and adolescents with a physical disability.MethodsThis controlled clinical trial included 71 children and adolescents from four schools for special education [mean age 13.7 (2.9 years, range 8–19, 55% boys]. Participants had various chronic health conditions including cerebral palsy (37%, other neuromuscular (44%, metabolic (8%, musculoskeletal (7%, and cardiovascular (4% disorders. Before recruitment and based on the presence of school-based sports, schools were assigned as sport or control group. School-based sports were initiated and provided by motivated experienced physical educators. The sport group (n = 31 participated in a once-a-week school-based sports program for 6 months, which included team sports. The control group (n = 40 followed the regular curriculum. Anaerobic performance was assessed by the Muscle Power Sprint Test. Secondary outcome measures included aerobic performance, VO2 peak, strength, physical activity, blood pressure, arterial stiffness, body composition, and the metabolic profile.ResultsA significant improvement of 16% in favor of the sport group was found for anaerobic performance (p = 0.003. In addition, the sport group lost 2.8% more fat mass compared to the control group (p = 0.007. No changes were found for aerobic performance, VO2 peak, physical activity, blood pressure, arterial stiffness, and the metabolic profile.ConclusionAnaerobic performance and fat mass improved following a school-based sports program. These effects are promising for long-term fitness and health promotion, because sports sessions at school eliminate certain barriers for sports participation and adding a once-a-week sports session showed already positive effects for 6 months.Clinical Trial RegistrationThis trial was registered with the Dutch Trial Registry (NTR

    Physical activity has a positive impact on people's well-being, and it may also decrease the occurrence of chronic diseases. Activity recognition with wearable sensors can provide feedback to the user about his/her lifestyle regarding physical activity and sports, and thus, promote a more active lifestyle. So far, activity recognition has mostly been studied in supervised laboratory settings. The aim of this study was to examine how well the daily activities and sports performed by the subjects in unsupervised settings can be recognized compared to supervised settings. The activities were recognized by using a hybrid classifier combining a tree structure containing a priori knowledge and artificial neural networks, and also by using three reference classifiers. Activity data were collected for 68 h from 12 subjects, out of which the activity was supervised for 21 h and unsupervised for 47 h. Activities were recognized based on signal features from 3-D accelerometers on hip and wrist and GPS information. The activities included lying down, sitting and standing, walking, running, cycling with an exercise bike, rowing with a rowing machine, playing football, Nordic walking, and cycling with a regular bike. The total accuracy of the activity recognition using both supervised and unsupervised data was 89% that was only 1% unit lower than the accuracy of activity recognition using only supervised data. However, the accuracy decreased by 17% unit when only supervised data were used for training and only unsupervised data for validation, which emphasizes the need for out-of-laboratory data in the development of activity-recognition systems. The results support a vision of recognizing a wider spectrum, and more complex activities in real life settings.

    Controversial results reported in past research pertaining to the effectiveness of sport-based physical activity interventions on weight loss. The purpose of this study was to assess the impact of sport-based physical activity intervention on body weight in children and adolescents using a meta-analysis. Academic Search Complete, Education Source, ERIC, Medline, ProQuest, PsycINFO and SportDiscus databases were searched from January 2000 to April 2015. Eighteen studies met following inclusion criteria: sport-based intervention studies; subjects aged 6-18 years; reported body weight; published in peer-reviewed journals written in English. The mean intervention duration was 17.72 weeks. The overall effect size (ES) was 0.52 (Cohen's d (ES) = 0.52, 95% CI = 0.08, 0.95, P = 0.021), using a random effects model. Moderator analyses results showed that the Q statistic for the sport type (individual sport or team sport, Qbetween (Q b ) = 14.52, df = 1, P = 0.001) and diet control (Qbetween (Q b ) = 8.85, df = 1, P = 0.001), explained the heterogeneity of ESs. Our study showed that there was a moderate overall effect of sport-based physical activity intervention on body weight reduction. The team sport type (ES = 1.05, 95% CI = 0.44, 1.66) and diet control group (ES = 0.84, 95% CI = 0.26, 1.41) appeared to be more effective in reducing body weight.

This review focuses on the inherent reduction of normal physical activity in pediatric oncology because this cutback additionally contributes to the level of burden of malignancies. Maintaining normality requires detailed analyses of disease-related and therapy-related restrictions and their justification. Relevant efforts should be stepped up to maintain physical activity levels during pediatric cancer therapy. Another aspect addresses direct therapeutic implications. Feasibility studies, nonrandomized as well as randomized investigations addressed therapeutic effects in acute hospital care, in bone marrow transplant settings, and in outpatient therapy. The overall summary shows positive effects on clinical and psychosocial outcome. Even if the basis of the data for children is still limited, there will be no doubt about a general impact of physical activity on acute side effects as well as late effects. In the areas of tension between context-related restrictions, the right to maintain normality wherever possible and the positive therapeutic and psychosocial perspectives of sports, strong efforts are needed to support physical activity wherever indicated, clarify contraindications, and overcome structural limitations.

    The main purpose of this study was to evaluate the differences in adolescents´ objective physical activity levels and perceived effort in physical education, school recess, and extra-curricular organized sport by motivational profiles in physical education. A sample of 102 students 11-16 yr. old completed a self-report questionnaire assessing self-determined motivation toward physical education. Subsequently, students' objective physical activity levels (steps/min., METs, and moderate-to-vigorous physical activity) and perceived effort were evaluated for each situation. Cluster analysis identified a two-cluster structure: "Moderate motivation toward physical education profile" and "High motivation toward physical education profile." Adolescents in the second cluster had higher physical activity and perceived effort values than adolescents in the first cluster, except for METs and moderate-to-vigorous physical activity in extra-curricular sport. These results support the importance of physical education teachers who should promote self-determined motivation toward physical education so that students can reach the recommended physical activity levels.

    Frailty is a common syndrome in older adults characterised by increased vulnerability to adverse health outcomes as a result of decline in functional and physiological measures. Frailty predicts a range of poor health and social outcomes and is associated with increased risk of hospital admission. The health benefits of sport and physical activity and the health risks of inactivity are well known. However, less is known about the role of sports clubs and physical activity in preventing and managing frailty in older adults. The objective of this study is to examine the role of membership of sports clubs in promoting physical activity and reducing levels of frailty in older adults. We used data from waves 1 to 7 of the English Longitudinal Study of Ageing (ELSA). Survey items on physical activity were combined to produce a measure of moderate or vigorous physical activity for each wave. Frailty was measured using an index of accumulated deficits. A total of sixty deficits, including symptoms, disabilities and diseases were recorded through self-report and tests. Direct and indirect relationships between sports club membership, levels of physical activity and frailty were examined using a cross-lagged panel model. We found evidence for an indirect relationship between sports club membership and frailty, mediated by physical activity. This finding was observed when examining time-specific indirect pathways and the total of all indirect pathways across seven waves of survey data (Est = -0.097 [95% CI = -0.124,-0.070], p = sports clubs may be useful in preventing and managing frailty in older adults, both directly and indirectly through increased physical activity levels. Sports clubs accessible to older people may improve health in this demographic by increasing activity levels and reducing frailty and associated comorbidities. There is a need for investment in these organisations to provide opportunities for older people to achieve the levels of physical activity

    As a society we are increasingly concerned about our physical appearance. For example, as much as 24% of people in developed countries admittedly exercise to improve their performance. Professional sportsmen and amateurs alike are in a constant search for new means that will enable them better sport results in shorter time. Among those means, a prominent place belongs to dietary supplements. However, the producers often advertise products whose use in sports is neither scientifically founded nor safe. This brings on an irrational use of herbal supplements which sometimes leads to unwanted side effects, but is more often of little use. Thus, the aim of this review will be to systematically evaluate some of the herbal supplements that are used as adaptogenic and ergogenic aids in sport. The review will include available data on Rhodiola rosea, Withania somnifera, Schisandra chinensis, Tribulus terrestris, Vitis vinifera, Citrus aurantium, and others. Their effects, active ingredients as well as possible adverse effects will be discussed with special focus on clinical studies.

    Full Text Available The new context competence system of vocational training requires the system-creating interdisciplinary link. However, the lack of such interrelation between the humanities, social, economic disciplines and professional subjects badly affects the training results. The quality of training process can be improved by introducing the interdisciplinary principle. In this regard, the authors carried out the research aimed at solving the above problem by developing the method of interdisciplinary correlation and analyzing its system-creating basis.The paper substantiates the possibility of developing students’ technological thinking by means of sports and physical education activity corresponding to a particular professional one according to the universal morphology classification. It is demonstrated that technological thinking can be developed in the context of sports games under several organizational and methodical conditions. One of the proposed conditions concerns the project of a sport game improvement. The given method can find its application in designing the training process related to physical education of students of different profiles.

    Strawberry (Fragaria ananassa Duch.) possesses good antioxidant properties. Phenolic compounds in strawberries, such as anthocyanins and ellagic acid, mainly act as antioxidants. This study aimed to compare the phenolic content and expression patterns of genes involved in flavonoid biosynthesis between summer and winter strawberry cultivars affected by seasonal variation, degree of ripeness, and genotype. Antioxidant activity and the total content of phenols and flavonoids decreased with fruit ripening. Most notably, summer strawberry cultivars showed higher antioxidant activity than winter cultivars. The expression patterns of flavonoid biosynthetic genes tested were cultivar-dependent and were also affected by ripening. These results help us understand the nutritional and physiological characteristics of selected cultivars and provide a range of information for strawberry consumption. © 2017 Institute of Food Technologists®.

    Full Text Available Skiing on the glaciers has emerged as one more of the prominent and interesting representatives of unusual and relatively young extreme discipline. His appearance has reflected at the same time on the direction of the tourist group, which are rightfully called the adrenaline lovers or adventurers (in the broadest sense. All this has contributed to expanding the current tourism and sports exploited space, stirring the limits of human movement high, ie. deep in the untouched area of permafrost. In the paper are noted the facts of the genesis of the glacier, the conditions that prevailing at this height (ie. improvised tracks, and of numerous effects that the presence of visitors leave on this particularly sensitive and specific eco-system. In the framework of the paper was conducted a research about the possible interest and awareness of domestic tourists (in the area of Novi Sad for this kind of active rest. The idea was to present data which suggest to a certain conclusions on these issues, with the aim of determining the relationship of citizens of Serbia to the current trends in the field of sports and recreational tourism (having in mind the objective possibility of taking an participate in the category of special travel arrangements, material restrictions and difficulties in implementation of the same by the tour. A general task of the paper was to draw the attention of respondents to the chosen topic indirectly, and that among the educated and professionally qualified persons from the world of sports and tourism, additionally promote the new direction of global interest in the domain of extreme and adventure sports. Viewed from another aspect, it is about desire to foster thinking on the possibilities and purposes of further commercialization of worldwide trend in our area (at a higher level than the existing one.

  8. Climate change in winter versus the growing-season leads to different effects on soil microbial activity in northern hardwood forests

    Mean winter air temperatures have risen by approximately 2.5˚ C per decade over the last fifty years in the northeastern U.S., reducing the maximum depth of winter snowpack by approximately 26 cm over this period and the duration of winter snow cover by 3.6 to 4.2 days per decade. Forest soils in this region are projected to experience a greater number of freeze-thaw cycles and lower minimum winter soil temperatures as the depth and duration of winter snow cover declines in the next century. Climate change is likely to result not only in lower soil temperatures during winter, but also higher soil temperatures during the growing-season. We conducted two complementary experiments to determine how colder soils in winter and warmer soils in the growing-season affect microbial activity in hardwood forests at Harvard Forest, MA and Hubbard Brook Experimental Forest, NH. A combination of removing snow via shoveling and buried heating cables were used to induce freeze-thaw events during winter and to warm soils 5˚C above ambient temperatures during the growing-season. Increasing the depth and duration of soil frost via snow-removal resulted in short-term reductions in soil nitrogen (N) production via microbial proteolytic enzyme activity and net N mineralization following snowmelt, prior to tree leaf-out. Declining mass specific rates of carbon (C) and N mineralization associated with five years of snow removal at Hubbard Brook Experimental Forest may be an indication of microbial physiological adaptation to winter climate change. Freeze-thaw cycles during winter reduced microbial extracellular enzyme activity and the temperature sensitivity of microbial C and N mineralization during the growing-season, potentially offsetting nutrient and soil C losses due to soil warming in the growing-season. Our multiple experimental approaches show that winter climate change is likely to contribute to reduced microbial activity in northern hardwood forests.

    This study examined whether participation in school team sports, exclusively or in combination with other extracurricular activities, is associated with higher levels of psychosocial functioning and healthy behavior than participation in other extracurricular activities alone or nonparticipation. The study sample includes 50,168 ninth grade public school students who completed an anonymous, voluntary statewide survey in 2001. Students were classified into four groups based on their participation in sports and other activities (such as clubs, volunteer work, band, choir, or music lessons): neither, both, other activities only, and sports only. Odds ratios for the group involved in both types of activities were significantly higher than those for all the other groups for all healthy behaviors and measures of connectedness, and significantly lower for all but one of the unhealthy behaviors. Students involved in sports, alone or in combination with other activities, had significantly higher odds than the other two groups for exercise, milk consumption, and healthy self-image, and significantly lower odds for emotional distress, suicidal behavior, family substance abuse, and physical and sexual abuse victimization. Students involved in other activities, alone or in combination with sports, had significantly higher odds than the other two groups for doing homework and significantly lower odds for alcohol consumption, marijuana use, and vandalism. The finding that abuse victims appeared to avoid sports but not other group activities raises concern and merits further research. Considering the potential benefits of participation in sports and other activities, more research is needed to identify and overcome barriers or deterrents, particularly for youth from low-income families.

    Based on a cropping system of "winter green manure-double rice", the 4 x 4 two-factor test was used to study the effects of different nitrogen (N) application levels and winter green manure application on soil active organic carbon (AOC) and the C pool management index. The aim was to explore the ecological effects of winter green manure on soil improvement and determine the appropriate application levels of N fertilizer and winter green manure for improved rice yield. Results were as follows: 1) Compared with the control, the SOC and AOC contents increased by 22.2% and 26.7%, respectively, under the green manure only treatment, but the SOC contents decreased by 0.6%-3.4% under the single N fertilizer treatment. Compared with the control, the soil C pool management index increased by 24.55 and 15.17 under the green manure only and green manure plus N fertilizer treatments, respectively, and reduced by 2.59 under the single N fertilizer treatment. Compared with no fertilization, the average microbial biomass carbon (MBC) increased by 54.0%, 95.2% and 14.3% under the green manure, green manure plus N fertilizer and single N fertilizer treatments, respectively. 2) The soil AOC content was significantly positively correlated with the C pool management index (P management index, and the correlation coefficient was significantly greater than that with the total organic C. These results suggested that application of winter green manure at proper rates with inorganic fertilizer could increase SOC contents and the soil C pool management index, improve soil quality and fertility.

    weather research and forecasting ===== The NASA Short-term Prediction Research and Transition (SPoRT) program has numerous modeling and data assimilation (DA) activities in which the WRF model is a key component. SPoRT generates realtime, research satellite products from the MODIS and VIIRS instruments, making the data available to NOAA/NWS partners running the WRF/EMS, including: (1) 2-km northwestern-hemispheric SST composite, (2) daily, MODIS green vegetation fraction (GVF) over CONUS, and (3) NASA Land Information System (LIS) runs of the Noah LSM over the southeastern CONUS. Each of these datasets have been utilized by specific SPoRT partners in local EMS model runs, with select offices evaluating the impacts using a set of automated scripts developed by SPoRT that manage data acquisition and run the NCAR Model Evaluation Tools verification package. SPoRT is engaged in DA research with the Gridpoint Statistical Interpolation (GSI) and Ensemble Kalman Filter in LIS for soil moisture DA. Ongoing DA projects using GSI include comparing the impacts of assimilating Atmospheric Infrared Sounder (AIRS) radiances versus retrieved profiles, and an analysis of extra-tropical cyclones with intense non-convective winds. As part of its Early Adopter activities for the NASA Soil Moisture Active Passive (SMAP) mission, SPoRT is conducting bias correction and soil moisture DA within LIS to improve simulations using the NASA Unified-WRF (NU-WRF) for both the European Space Agency's Soil Moisture Ocean Salinity and upcoming SMAP mission data. SPoRT has also incorporated real-time global GVF data into LIS and WRF from the VIIRS product being developed by NOAA/NESDIS. This poster will highlight the research and transition activities SPoRT conducts using WRF, NU-WRF, EMS, LIS, and GSI.

    Abstract When reducing activity and using stored energy during seasonal food shortages, animals risk degradation of skeletal muscles, although some species avoid or minimize the resulting atrophy while experiencing these conditions during hibernation. Polar bears may be food deprived and relatively inactive during winter (when pregnant females hibernate and hunting success declines for other demographic groups) as well as summer (when sea ice retreats from key foraging habitats). We investigated muscle atrophy in samples of biceps femoris collected from free-ranging polar bears in the Southern Beaufort Sea (SBS) throughout their annual cycle. Atrophy was most pronounced in April–May as a result of food deprivation during the previous winter, with muscles exhibiting reduced protein concentration, increased water content, and lower creatine kinase mRNA. These animals increased feeding and activity in spring (when seal prey becomes more available), initiating a period of muscle recovery. During the following ice melt of late summer, ~30% of SBS bears abandon retreating sea ice for land; in August, these ‘shore’ bears exhibited no muscle atrophy, indicating that they had fully recovered from winter food deprivation. These individuals subsequently scavenged whale carcasses deposited by humans and by October, had retained good muscle condition. In contrast, ~70% of SBS bears follow the ice north in late summer, into deep water with less prey. These ‘ice’ bears fast; by October, they exhibited muscle protein loss and rapid changes in myosin heavy-chain isoforms in response to reduced activity. These findings indicate that, unlike other bears during winter hibernation, polar bears without food in summer cannot mitigate atrophy. Consequently, prolonged summer fasting resulting from climate change-induced ice loss creates a risk of greater muscle atrophy and reduced abilities to travel and hunt. PMID:28835844

    Actual and perceived object control (commonly ball) skill proficiency is associated with higher physical activity in children and adolescents. Active video games (AVGs) encourage whole body movement to control/play the electronic gaming system and therefore provide an opportunity for screen time to become more active. The purpose of this study was to determine whether playing sports AVGs has a positive influence on young children's actual and perceived object control skills. Two group pre/post experimental design study. Thirty-six children aged 6-10 years old from one school were randomly allocated to a control or intervention condition. The Test of Gross Motor Development-3 assessed object control skill. The Pictorial Scale of Perceived Competence for Young Children assessed perceived object control skill. The intervention consisted of 6×50min lunchtime AVG sessions on the Xbox Kinect. Two to three sport games were chosen for participants to play each session. General linear models with either perceived object control or actual object control skill as the outcome variables were conducted. Each base model adjusted for intervention status and pre-score of the respective outcome variable. Additional models adjusted for potential confounding variables (sex of child and game at home). No significant differences between the control and intervention groups were observed for both outcomes. This study found that playing the Xbox Kinect does not significantly influence children's perceived or actual object control skills, suggesting that the utility of the Xbox Kinect for developing perceived and actual object control skill competence is questionable.

    Little is known about long-term sporting activity after periosteal autologous chondrocyte implantation (ACI-P) and its correlation to clinical, morphological, and ultrastructural cartilage characteristics on magnetic resonance imaging (MRI). To evaluate long-term sporting activity after ACI-P and to correlate with clinical and MRI findings. Case series; Level of evidence, 4. Patients who underwent ACI-P for isolated cartilage defects of the knee joint between 1997 and 2001 were analyzed for sporting ability for 3 different time points: lifetime until the onset of pain, the year before ACI-P, and 11 years (range, 9.0-13.4 years) postoperatively. Sporting activity was assessed and patients' level of activity scaled using standardized questionnaires. MRI scans of the affected knee joint at follow-up were analyzed using the MOCART (magnetic resonance observation of cartilage repair tissue) score and T2 mapping. Seventy of 86 patients (81% follow-up rate) consisting of 25 female and 45 male patients, with a mean age of 33.3 ± 10.2 years at the time of surgery, mean defect size of 6.5 ± 4.0 cm 2 , and 1.17 treated defects per patient, agreed to participate in the study at a mean 10.9 ± 1.1 years after ACI-P. Fifty-nine patients (69% of total; 84% of follow-up) agreed to MRI, allowing the complete evaluation of 71 transplant sites. Before the onset of symptoms (lifetime), 95.7% of patients played a mean 6.0 sporting activities at a competitive level. In the year before ACI-P, 81.4% of patients played a mean 3.4 sporting activities in 2.4 sessions during 5.4 hours per week at a recreational level. At follow-up, 82.9% of the patients played a mean 3.0 sporting activities in 1.8 sessions during 3.0 hours per week at a recreational level. In contrast to objective factors, 65.6% of the patients felt that their subjective sporting ability had improved or strongly improved after ACI-P, whereas 12.9% felt that their situation had declined or strongly declined, and 21.4% stated

    We aimed to increase understanding of the link between sport specialization during childhood and adolescent physical activity (PA). The objectives were as follows: (1) describe the natural course of sport participation over 5 years among children who are early sport samplers or early sport specializers and (2) determine if a sport participation profile in childhood predicts the sport profile in adolescence. Participants ( n = 756, ages 10-11 years at study inception) reported their participation in organized and unorganized PA during in-class questionnaires administered every 4 months over 5 years. They were categorized as early sport samplers, early sport specializers, or nonparticipants in year 1 and as recreational sport participants, performance sport participants, or nonparticipants in years 2 to 5. The likelihood that a childhood sport profile would predict the adolescent profile was computed as relative risks. Polynomial logistic regression was used to identify predictors of an adolescent sport profile. Compared with early sport specialization and nonparticipation, early sport sampling in childhood was associated with a higher likelihood of recreational participation (relative risk, 95% confidence interval: 1.55, 1.18-2.03) and a lower likelihood of nonparticipation (0.69, 0.51-0.93) in adolescence. Early sport specialization was associated with a higher likelihood of performance participation (1.65, 1.19-2.28) but not of nonparticipation (1.01, 0.70-1.47) in adolescence. Nonparticipation in childhood was associated with nearly doubling the likelihood of nonparticipation in adolescence (1.88, 1.36-2.62). Sport sampling should be promoted in childhood because it may be linked to higher PA levels during adolescence. Copyright © 2017 by the American Academy of Pediatrics.

    Full Text Available It is well known that body activities are needed in child such as food and drink. Nowadays way of life causes reduced movement in whole population, such as in preeschool children. Reducing movement in preeschool children can result many postural disturbances and body deformities. In that case it was made systematic medical chackup in children 5-6 years old from ’’Cvrčak’’- Niš kindergarden on food deformities during last seven years (2004-2010. Received results showed desastrous level on food arch, reduced function of food muscules. The idea was that reason for that was childs` reduced body activities, from 2008. year it was made and start to realize the project „komunication and culture in sport“, in regard to grow up sport culture level in children, parents and teachers. As all of us is born having some predispozitions, it was given chance to sport clubs to present to children, teachers and parents all of sport-recreative bases. In cooperation with physical education expert service Office and coatches from sport clubs in Niš, it was made the sport-recreative Project. In one cyclus during one year children are included in next sports: rhythmic gymnastics, judo, tennis, basketball, vollyball, foodball, athledics, skating, skiing. The project gave wonderfull results: a great number of children joined sport clubs, more sport-recreative activities in children, growing right mind about body exercises needs, such as better statistic results after childrens` systematic medical chackup in 2009. and 2010. year. Mentioned Project is lasted till now.

It embraces the physical and mental health protection and promotion of participants in relation to a particular sport activity and sport environment, directing athletes to a sport and adapting them to sport and the sport to them. Sports medicine takes part in selection procedure, training process planning and programming, and cares for epidemiological, hygienic, nutritional and other problems in sport. The Republic of Croatia belongs to those world states in which the field of sports medicine is regulated neither by a law or by profession. A consequence is that wide circle of physicians and paramedics work in clubs and various medical units without any legal or/and professional control not being adequately educated nor having licence for it. This review is an appeal to the Croatian Medical Chamber and the Ministry of Health to make efforts to promote the education and medical profession in sports medicine.

    To evaluate the associations of physical activity and sports team participation with suicidal behavior among U.S. high school students. Data were from the 2003 Youth Risk Behavior Survey (N = 10,530 respondents). Exposure variables included physical activity (inactive, insufficient, moderately intensive, regular vigorously intensive, and frequent vigorously intensive) and sports team participation. Outcome variables were suicide ideation (seriously considering and/or planning suicide) and suicide attempts. Hierarchical logistic regressions were run, controlling for age, race, smoking, alcohol use, drug use, geographic region, unhealthy weight-control practices, and body mass index/weight perceptions. Compared with inactive students or sports team nonparticipants, the odds of suicide ideation were lower among boys reporting frequent vigorous-intensity physical activity (adjusted odds ratio (AOR) = 0.48; 95% confidence interval (CI) = 0.29, 0.79) and sports team participation, respectively (AOR = 0.65; 95% CI = 0.48, 0.86). The odds of suicide attempts were also lower among frequently vigorously active boys (AOR = 0.44; 95% CI = 0.21, 0.96) and sports team participants (AOR = 0.61; 95% CI = 0.40, 0.93). The odds of suicide attempts were lower for regular vigorously active girls compared with inactive girls (AOR = 0.67; 95% CI = 0.45, 0.99) and sports team participants compared with nonparticipants (AOR = 0.73; 95% CI = 0.57, 0.94). Associations with one exposure variable generally weakened when adjustment was made for the other exposure variable, or for feeling sad and hopeless. The association of physical activity and sports team participation with suicide ideation and suicide attempts varied by sex. Further research is needed to clarify these different associations.

    To elucidate whether extracurricular sports activity during rapid growth correlates with improved bone properties in late adolescence, a longitudinal observation was performed among 96 high-school enrollments (46 boys and 50 girls, born in 1981-1982) in metropolitan Tokyo. In each year of high school, tibial cortical speed of sound (TCSOS) was measured by quantitative ultrasonometry, and participation in extracurricular sports activity (ECSA) since primary school was examined by structured questionnaire. We calculated the number of years since peak height velocity (ysPHV) based on annual records of height from 6 to 18 y of age to indicate progression of puberty. The increase in TCSOS during high school in boys (32.5 m/s) was significantly greater than that in girls (5.4 m/s). The magnitude of positive association between ysPHV and TCSOS attenuated gradually over time. ECSA in grades 7-9 in boys and in grades 4-6 in girls were significant predictors of TCSOS throughout high school, independent of potential confounders. The bone benefits of ECSA around the growth spurt are maintainable in subsequent years. The importance of physical activities that are integrated into the ordinary lifestyle of children and adolescents during this crucial period is emphasized.

    Full Text Available Motivation in physical activity constitutes a multidimensional psychological characteristic that is influenced by the person’s internal aspects (preferences, desires, fears, etc. and his/her experiences in the external environment (social acceptance, friends, skills, etc..  In a period in which physical activity is globally increasing among people of all ages, it is important for physical educators, sports trainers, or physical instructors to know the main reasons for their trainees to exercise with the purpose of preparing ideal workout plans that would help them continue exercising.  These plans should encourage subjects to enjoy and be satisfied with their participation, therefore, extending their active life cycle and avoiding quitting, which are closely related to a sedentary lifestyle and the risk of having chronic and degenerative diseases.  Consequently, children prefer to exercise to have fun and make friends, adolescents to compete and make friends, college students for adventure and fun, adults to have regular physical activity, and senior citizens to obtain health benefits.  Women are motivated by their appearance and social reasons, while men do it for competition and status.  Subjects who practice sports are motivated by competition, while those who exercise do it for body image.  The more physical activity is practiced the more value is given to competition.  Finally, having fun, competing, learning skills, and being in good physical condition are the most relevant reasons for American, European, and Asian subjects to participate in physical activity.  This research was conducted with the purpose of letting professionals of human movement sciences know the variables that determine the reasons for subjects of distinctive ages, gender, culture, and level of activity to participate in the different types of physical activities.

    The purpose of this study was to clarify the effect of colored lenses on visual attributes related to sports activities. The subjects were 24 students (11 females, 13 males; average age 21.0 ±1.2 years) attending a sports university. Lenses of 5 colors were used: colorless, light yellow, dark yellow, light gray, and dark gray. For each lens, measurements were performed in a fixed order: contrast sensitivity, dynamic visual acuity, depth perception, hand-eye coordination and visual acuity and low-contrast visual acuity. The conditions for the measurements of visual acuity and low-contrast visual acuity were in the order of Evening, Evening+Glare, Day, and Day+Glare. There were no significant differences among lenses in dynamic visual acuity and depth perception. For hand-eye coordination, time was significantly shorter with colorless than dark gray lenses. Contrast sensitivity was significantly higher with colorless, light yellow, and light gray lenses than with dark yellow and dark gray lenses. The low-contrast visual acuity test in the Day+Glare condition showed no significant difference among the lenses. In the Evening condition, low-contrast visual acuity was significantly higher with colorless and light yellow lenses than with dark gray lenses, and in the Evening+Glare condition, low-contrast visual acuity was significantly higher with colorless lenses than with the other colors except light yellow. Under early evening conditions and during sports activities, light yellow lenses do not appear to have an adverse effect on visual attributes.

    To describe correlates of physical activity (PA) in structured exercise and structured sports sessions among low-income, overweight children participating in a community-based PA program. A total of 93 children (55% male; 91% Hispanic) aged 8-14 years were included. Participants wore pedometers in a sample of 10 of 59 total sessions offered; mean steps per minute were calculated for structured exercise and sports sessions. Separate multivariable regression models tested associations between steps per minute in exercise and sports sessions and 5 potential correlates: baseline body mass index z-score, aerobic fitness (Progressive Aerobic Cardiorespiratory Endurance Run laps), perceived athletic competence (Harter self-perception profile), sex, and age. Only age (ß = -2.9; P = .02) significantly predicted steps per minute in exercise sessions. Age (ß = -4.3; P = .007), fitness (ß = 0.45; P = .03), and male sex (ß = 8.7; P = .02) significantly predicted steps per minute in sports. In structured exercise and sports, perceived competence may not influence overweight and obese children's PA. However, girls and older or less fit children may engage less actively, especially in sports. Copyright © 2015 Society for Nutrition Education and Behavior. Published by Elsevier Inc.

    Although seasonal snow is recognized as an important component in the global climate system, the ability of snow to affect plant production remains an important unknown for assessing climate change impacts on vegetation dynamics at high-latitude ecosystems. Here, we compile data on satellite observation of vegetation greenness and spring onset date, satellite-based soil moisture, passive microwave snow water equivalent (SWE) and climate data to show that winter SWE can significantly influence vegetation greenness during the early growing season (the period between spring onset date and peak photosynthesis timing) over nearly one-fifth of the land surface in the region north of 30 degrees, but the magnitude and sign of correlation exhibits large spatial heterogeneity. We then apply an assembled path model to disentangle the two main processes (via changing early growing-season soil moisture, and via changing the growth period) in controlling the impact of winter SWE on vegetation greenness, and suggest that the "moisture" and "growth period" effect, to a larger extent, result in positive and negative snow-productivity associations, respectively. The magnitude and sign of snow-productivity association is then dependent upon the relative dominance of these two processes, with the "moisture" effect and positive association predominating in Central, western North America and Greater Himalaya, and the "growth period" effect and negative association in Central Europe. We also indicate that current state-of-the-art models in general reproduce satellite-based snow-productivity relationship in the region north of 30 degrees, and do a relatively better job of capturing the "moisture" effect than the "growth period" effect. Our results therefore work towards an improved understanding of winter snow impact on vegetation greenness in northern ecosystems, and provide a mechanistic basis for more realistic terrestrial carbon cycle models that consider the impacts of winter snow

    Vitamin D status [25(OH)D] has recently been reported to be associated with altered cellular bioenergetic profiles of peripheral blood mononuclear cells (PBMCs). No study has tracked the seasonal variation of 25(OH)D and its putative influence on whole body energy metabolism, cellular bioenergetic profiles, inflammatory markers and clinical chemistry. Whole body energy metabolism and substrate utilisation were measured by indirect calorimetry. PBMCs obtained from the same subjects were isolated from whole blood, counted and freshly seeded. Bioenergetic analysis (mitochondrial stress test and glycolysis stress test) was performed using the Seahorse XF e 96 flux analyser. 25(OH)D was assessed using the Architect immunoassay method. 25(OH)D increased by a median (IQR) of 14.40 (20.13)nmol/L (pwinter to summer and was accompanied by significant improvements in indices of insulin sensitivity, McAuley's index (p=0.019) and quantitative insulin sensitivity check index (p=0.028). PBMC mitochondrial parameters basal respiration, non-mitochondrial respiration, ATP production, proton leak, and maximal respiration decreased in summer compared to winter. Similarly, PBMC glycolytic parameters glycolytic activity, glucose response, and glycolytic capacity were all reduced in summer compared to winter. There was also a trend for absolute resting metabolic rate (RMR) to decrease (p=0.066). Markers of systemic inflammation MCP-1, IL-6, IL-8, IL-10, and IL-12p70 decreased significantly in summer compared to winter. Participants who entered winter with a low 25(OH)D (winter 25(OH)D concentrations of 50-75nmol/L or >75nmol/L. The absolute change in 25(OH)D was not associated with altered bioenergetics. Seasonal improvements in 25(OH)D was associated with reduced systemic inflammation, PBMC bioenergetic profiles and whole body energy metabolism. These observational changes in PBMC bioenergetics were most pronounced in those who had insufficient 25(OH)D in winter. The data warrants

    Sports medicine covers many different aspects, ranging from clinical specialties, such as internal medicine, orthopedics or pediatrics to physiology and sports sciences. The requirements for sports medicine evolve mainly from exercise physiology (elite, leisure and health oriented physical activity), orthopedics and traumatology as well as from preventive and rehabilitative issues. In the new German curriculum, sports medicine is defined as a subspecialty. Historically, sports medicine in Germany has a federal structure with a governing body (Deutsche Gesellschaft für Sportmedizin und Prävention). Due to these facts, University Departments of Sports Medicine (which vary greatly in size and performance) are either attached to Medical or non-Medical Faculties, such as Sports Sciences. In medical schools, sports medicine can be selected as an elective subject. However, the main part of teaching sports medicine is covered by Sports Science Faculties. In an international context, the strength of German sports medicine is its clinical orientation and close cooperation with the sport itself, especially high-performance sports. In the future, like in the Anglo- American countries, sports medicine in Germany will play a major role in health prevention and rehabilitation.

    Extratropical cyclone activity over Eurasia has exhibited a weakening trend in the recent decade. Extratropical cyclones bring precipitation and hence supply fresh water for winter crops in the mid- and high-latitude regions of Eurasia. Any changes in extratropical cyclone activity over Eurasia in the future may have a critical impact on winter agriculture and the economies of affected communities. However, potential future changes in regional storm activity over Eurasia have not been studied in detail. Therefore, in this study, we investigate anticipated changes in extratropical storm activity by the end of the century through a detailed examination of the historical and future emission scenarios from six different models from CMIP5. A statistical analysis of different parameters of storm activity using a storm identification and tracking algorithm reveals a decrease in the number of storms over mid-latitude regions. However, intense storms with longer duration are projected over high latitude Eurasia. A further examination of the physical mechanism for these changes reveals that a decrease in the meridional temperature gradient and a weakening of the vertical wind shear over the mid-latitudes are responsible for these changes in storm activity.

    Eighty per cent of severe sports-related central nervous system trauma occurs as a result of collision sports, chiefly American football and rugby union football, followed by wrestling and gymnastics. Although serious head injury is uncommon, episodes of concussion are frequent; repeated concussion should be grounds for suggesting that the athlete give up collision sport. American and rugby union football are the sports mainly responsible for cervical spine injury with resultant quadriplegia.

    The purpose of this study was to examine the influence of vitamin D status on mucosal and systemic immunity and the incidence, severity and duration of upper respiratory tract illness (URTI) episodes in endurance athletes during a 16-week winter training period. Blood was collected from 225 subjects at the start of the study and plasma was analysed for total 25-hydroxy vitamin D (25(OH)D) and cathelicidin concentration. Blood was also collected at the end of the study and analysed for 25(OH)D and antigen-stimulated cytokine production. Unstimulated saliva samples were obtained at the start and at 4-week intervals during the study period. Saliva samples were analysed for salivary antimicrobial peptides and proteins (AMPs). Weekly training and daily illness logs were kept. At the start and end of the study 38% and 55%, respectively, of the athlete cohort had inadequate (plasma 25(OH)D 30-50 nmol/L) or deficient (plasma 25(OH)D 120 nmol/L) and the total number of URTI symptom days and the median symptom-severity score in the vitamin D deficient group was signifi- cantly higher than in the other groups. The plasma cathelicidin concentration positively correlated with the plasma 25(OH)D concentration and the saliva secretory immunoglobulin A (SIgA) secretion rate in the optimal vitamin D status group was significantly higher than in the other groups. Low vitamin D status was associated with lower pro-inflammatory cytokine production by monocytes and lymphocytes. Low vitamin D status could be an important determinant of URTI risk in endurance athletes and mucosal as well as systemic immunity may be modified via vitamin D-dependent mechanisms.

    Full Text Available This research paper aims to see to what extent a project of revitalization of playgrounds contributes to improving coexistence, conflict resolution, and the participation of boys and girls in sport and physical activities. The paper also aims to know the level of motivation and interest the project could have for the students. For this, after initial assessment, a project of revitalization of recreations was designed, and after a few days of training, it was implemented for a month in a primary school in Spain, with 179 students (98 boys and 81 girls from 1 to 6 grades; it was carried out in the school playground during a 30-minute recess period. The project consisted of two phases of training; the first one explained different games through training days; the second phase featured free recreation and independent work. The project opted for a mixed methodology of collecting information; this methodology included an information questionnaire and participant observation. The study concludes by highlighting the students’ high interest and motivation, the increasing participation, both boys and girls in physical and sports activities, and the reduction of conflicts between students of the center.

    The clinical diagnosis and management of patients with sport-related concussion is largely dependent on subjectively reported symptoms, clinical examinations, cognitive, balance, vestibular and oculomotor testing. Consequently, there is an unmet need for objective assessment tools that can identify the injury from a physiological perspective and add an important layer of information to the clinician's decision-making process. The goal of the study was to evaluate the clinical utility of the EEG-based tool named Brain Network Activation (BNA) as a longitudinal assessment method of brain function in the management of young athletes with concussion. Athletes with concussion (n = 86) and age-matched controls (n = 81) were evaluated at four time points with symptom questionnaires and BNA. BNA scores were calculated by comparing functional networks to a previously defined normative reference brain network model to the same cognitive task. Subjects above 16 years of age exhibited a significant decrease in BNA scores immediately following injury, as well as notable changes in functional network activity, relative to the controls. Three representative case studies of the tested population are discussed in detail, to demonstrate the clinical utility of BNA. The data support the utility of BNA to augment clinical examinations, symptoms and additional tests by providing an effective method for evaluating objective electrophysiological changes associated with sport-related concussions.

    Autologous chondrocyte implantation (ACI) has been associated with satisfying results in everyday activities. Clinical results after ACI treatment of femorotibial lesions are superior in comparison with patellofemoral lesions. There is limited information regarding at which level recreational, amateur, and professional athletes can resume sports and physical activities as well as work after ACI and what parameters influence return to work and sports. Return to sports activity and work is dependent on defect characteristics such as location and size. Case series; Level of evidence, 4. A total of 130 patients with isolated full-thickness cartilage defects of the knee joint treated with ACI between June 2000 and October 2007 were retrospectively studied by an established questionnaire that assessed sports-specific questions such as frequency, duration, and intensity. Engagement in 32 different sports disciplines was evaluated. In addition, work-specific data were evaluated according to classifications established by the REFA Association. Results were evaluated depending on patient- and defect-specific parameters. The mean ± SD patient age at ACI was 36.2 ± 9.2 years, with a mean defect size of 4.4 ± 1.7 cm(2). Defects were located at the femorotibial compartment in 55.7% of cases, whereas lesions of the patellofemoral compartment were found in 44.3%. Mean duration of inability to work after ACI was 13.6 ± 11.0 weeks and did not appear to be influenced by patient age. Defect location and defect size did not appear to significantly influence return-to-work rates, but work intensity before surgery significantly influenced return-to-work rates and duration of absence from work. Workplace adaptations were necessary in only 9.2% of cases postoperatively. With regard to postoperative sports activity, 73.1% of patients were able to return to sports. Neither defect location nor size significantly influenced return to physical activity. Patients participated in a mean of 2

    The aim was to compare the effect of a simulated team sport activity circuit (reflective of the activity demands of Australian football) either with or without body 'contact' on muscle soreness, damage, and performance when the circuit was repeated 48 h later. Eleven male, team-sport athletes completed a 'non-contact' (NCON) and a 'contact' (CON) version of the team sport activity circuit in a crossover design with at least 1 week between trials. The effect of CON and NCON on repeated 15m sprint and vertical jump performance was assessed by completing the same version of the circuit 48 h after the initial trial. The effect on perceived soreness and blood markers of muscle damage and inflammation was also determined. Subsequent performance was affected to a greater extent by CON, with both best and mean sprint times significantly slower 48h following CON (psoreness and pressure sensitivity were elevated following both NCON and CON (psoreness was greater with CON (p=0.012). Both CON and NCON resulted in elevated serum creatine kinase, myoglobin and lactate dehydrogenase, while c-reactive protein increased following CON but not NCON. In conclusion, Greater perceived soreness and decrements in performance of the simulated team sport activity circuit when repeated 48 h later were observed following CON.

  2. fMRI and brain activation after sport concussion: a tale of two cases

    Full Text Available Sport-related concussions are now recognized as a major public health concern: The number of participants in sport and recreation is growing, possibly playing their games faster, and there is heightened public awareness of injuries to some high-profile athletes. However, many clinicians still rely on subjective symptom reports for the clinical determination of recovery. Relying on subjective symptom reports can be dangerous, as it has been shown that some concussed athletes may downplay their symptoms. The use of neuropsychological (NP testing tools has enabled clinicians to measure the effects and extent of impairment following concussion more precisely, providing more objective metrics for determining recovery after concussion. Nevertheless, there is a remaining concern that brain abnormalities may exist beyond the point at which individuals achieve recovery in self-reported symptoms and cognition measured by NP testing. Our understanding of brain recovery after concussion is important not only from a neuroscience perspective, but also from the perspective of clinical decision making for safe return-to-play (RTP. A number of advanced neuroimaging tools, including blood oxygen level dependent (BOLD functional magnetic resonance imaging (fMRI, have independently yielded early information on these abnormal brain functions. In the two cases presented in this article, we report contrasting brain activation patterns and recovery profiles using fMRI. Importantly, fMRI was conducted using adapted versions of the most sensitive computerized NP tests administered in current clinical practice to determine impairments and recovery after sport-related concussion. One of the cases is consistent with the concept of lagging brain recovery.

    Culturally and linguistically diverse (CALD) migrants face significant health risks as they adapt to new cultures. These risks are exacerbated by their limited participation in preventative behaviours such as sports and physical activity. The review aimed to identify studies that examined the correlates of sport and physical activity participation in migrants. The systematic review identified 72 papers, including 6 interventions, 18 qualitative and 48 quantitative studies. The 44 identified correlates highlight the complexities involved in working with migrants. The correlates were grouped in four themes using the social ecological model; acculturation, demographic, psychosocial and environmental/organisational. The social ecological model identified general correlates such as social support and safety. However, there were unique correlates relating to individuals who are facing cultural changes such as acculturation and language. Overall, there is a lack of contextualisation of CALD migrants' sport and physical activity experiences because many studies fail to consider acculturation comprehensively.

    People's feelings toward physical activity are often influenced by memories of their childhood experiences in physical education and sport. Unfortunately, many adults remember negative experiences, which may affect their desire to maintain a physically active lifestyle. A survey that asked 293 students about recollections from their childhood…

    People today are living longer and want to remain active. While obesity is becoming an epidemic, the number of patients suffering from osteoarthritis (OA) is expected to grow exponentially in the coming decades. Patients with OA of the knee are progressively being restricted in their activities. Since a knee arthroplasty (KA) is a well accepted, cost-effective intervention to relieve pain, restore function and improve health-related quality of life, indications are expanding to younger and more active patients. However, evidence concerning return to sports (RTS) and physical activity (PA) after KA is sparse. Our aim was to systematically summarise the available literature concerning the extent to which patients can RTS and be physically active after total (TKA) and unicondylar knee arthroplasty (UKA), as well as the time it takes. PRISMA guidelines were followed and our study protocol was published online at PROSPERO under registration number CRD42014009370. Based on the keywords (and synonyms of) 'arthroplasty', 'sports' and 'recovery of function', the databases MEDLINE, Embase and SPORTDiscus up to January 5, 2015 were searched. Articles concerning TKA or UKA patients who recovered their sporting capacity, or intended to, were included and were rated by outcomes of our interest. Methodological quality was assessed using Quality in Prognosis Studies (QUIPS) and data extraction was performed using a standardised extraction form, both conducted by two independent investigators. Out of 1115 hits, 18 original studies were included. According to QUIPS, three studies had a low risk of bias. Overall RTS varied from 36 to 89% after TKA and from 75 to >100% after UKA. The meta-analysis revealed that participation in sports seems more likely after UKA than after TKA, with mean numbers of sports per patient postoperatively of 1.1-4.6 after UKA and 0.2-1.0 after TKA. PA level was higher after UKA than after TKA, but a trend towards lower-impact sports was shown after both TKA

    Objective. To understand the relationships between participation in different types of leisure time sport activity and adolescent obesity, and how those relationships might differ based on race, gender, and household income. Methods. Data consisted of 6667 students that took part in the 1999 to 2006 National Health and Nutrition Examination Survey. The authors used adjusted Wald tests to examine differences in the prevalence of obesity (body mass index >95th percentile for age and sex) by sport for boys and girls separately. Results. Among adolescent youth age 12 to 19 years, 16.6% of male leisure time sport participants and 15.3% of female sport participants were obese, compared with 23.6% for male nonathlete participant-in-other-activities and 17.0% obesity rate for female nonathlete/participant-in-other-activities. For both males and females, reported participation in leisure time sports decreased between middle school and high school, and this reduction was associated with higher body mass index.

    Male fish are susceptible to developing intersex, a condition characterized by the presence of testicular oocytes. In the present study, the relationship between intersex and exposure to estrogenic endocrine active contaminants (EACs) was assessed for 2 genera of sport fish, Micropterus and Lepomis, at 20 riverine sites. Seasonal trends and relationships between EACs and intersex (prevalence and severity) were examined at varying putative sources of EACs throughout North Carolina, identified as point sources, nonpoint sources, and reference sites. Intersex was identified in both genera, which was documented for the first time in wild-caught Lepomis. Intersex was more prevalent (59.8%) and more severe (1.6 mean rank) in Micropterus, which was highly correlation to EACs in sediment. In contrast, intersex was less common (9.9%) and less severe (0.2 mean rank) in Lepomis and was highly correlated to EACs in the water column. The authors found that concentrations of polycyclic aromatic hydrocarbons, polychlorinated biphenyls, industrial EACs, and estrogens were highest at point source sites; however, no source type variation was identified in the prevalence or severity of intersex, nor were there seasonal trends in intersex or EAC concentrations. The authors’ results associate genus-specific prevalence of intersex with specific EAC classes in common sport fishes having biological, ecological, and conservation implications.

    Our baseline sample included 1999 children, of whom 50% were female. Mean BMI increased over the study period from 19.0 (SD = 3.7 to 21.2 (SD = 4.1, while organized sport participation declined. Model results showed that BMI and sport are weakly associated, and that each of these variables predicts the other, which generally supports a bidirectional relationship. Consistent with some previous reports, however, the effect size in both directions is very small. At the levels of participation in our sample, activity and BMI are very weakly related. Findings should not obscure the other benefits of physical activity.

  1. Winter Activity and Aboveground Hybridization Between the Two Biotypes of the West Nile Virus Vector Culex pipiens.

    Culex (Cx.) pipiens mosquitoes are important vectors of West Nile virus (WNV). In Europe, the species Cx. pipiens consists of two biotypes, pipiens and molestus, which are morphologically identical, but differ in behavior. Typical behavior of the molestus biotype is the ability to remain active during winter, whereas the pipiens biotype enters diapause. The current paradigm is that the two biotypes occur sympatrically in southern Europe, but occur in isolated above- and belowground populations in northern Europe. In northern Europe, hybridization between biotypes is considered to be low because of the barrier that exists between typical habitats. Data on the occurrence of the biotypes and hybrids in northern Europe, however, are scarce, because identification to the level of biotype is often not performed. Our objective was to clarify the distribution of the Cx. pipiens biotypes and to determine hybridization rates in The Netherlands. Cx. pipiens mosquitoes were collected using three different approaches. First, traps were deployed randomly throughout The Netherlands during the summers of 2011 and 2012 (active surveillance). Second, using a web-based reporting platform and media campaign, Dutch citizens were asked to send dead mosquitoes to our laboratory during the winter and summer of 2014 (passive surveillance). Third, larvae and adults were collected during the summer of 2014 from aboveground locations in Amsterdam to identify molestus larval habitats. Real-time PCR was used for identification to the level of biotype. We found that biotype molestus and hybrids were feeding indoors during winter and summer in The Netherlands and that hybridization rates ranged between 6% and 15%. Larval habitats of biotype molestus were found to occur aboveground. The high percentage of hybridization has implications for assessing the risk of WNV transmission, because hybrids are thought to have ideal characteristics for bridging WNV between birds and humans.

    The article explores the process of "sportification"--i.e., processing physical activity in a sport regulated by a set of rules and standards, legitimized by supervisory institutions--from two originals practices, parkour and urban golf. To study these practices, we crossed the contributions of urban sociology and of the contemporary sociology of sport while respecting the methodological principles of qualitative sociology. A first point concerns the process of"sport" itself, its definition, its various stages, and the role played by communication of stakeholders on public space. The cultural mediation shows us how to institutionalize the movement that represents the "sports" resulted in the same time reconfiguration of physical practices themselves. Recent events illustrate the ongoing reconfiguration, we will detail them. Finally, we show the effects produced by the process on the definition of urban culture and sports: setting sight of activities, enhanced cooperation with the media-cultural, polarization between different types of practical in the case of parkour, around a confrontation between two of the founders.

    The present study identified adolescents' motor competence (MC)-based profiles (e.g., high actual and low perceived MC), and accordingly investigated differences in motivation for physical education (PE), physical activity (PA) levels, and sports participation between profiles by using regression analyses. Actual MC was measured with the Körperkoordinationstest für Kinder. Adolescents (n = 215; 66.0% boys; mean age = 13.64 ± .58 years) completed validated questionnaires to assess perceived MC, motivation for PE, PA-levels, and sports participation. Actual and perceived MC were only moderately correlated and cluster analyses identified four groups. Two groups of overestimators (low - overestimation, average - overestimation) were identified (51%), who particularly displayed better motivation for PE when compared to their peers who accurately estimated themselves (low - accurate, average - accurate). Moreover, adolescents with low actual MC, but high perceived MC were significantly more active than adolescents with low actual MC who accurately estimated themselves. Results pointed in the same direction for organised sports participation. Underestimators were not found in the current sample, which is positive as underestimation might negatively influence adolescents' motivation to achieve and persist in PA and sports. In conclusion, results emphasise that developing perceived MC, especially among adolescents with low levels of actual MC, seems crucial to stimulate motivation for PE, and engagement in PA and sports.

    Full Text Available Purpose: The objective of this article is to know if there are differences in the variables that explain the entrepreneurial intention of the Physical Activity and Sport Science students addressing academic training and gender of them. Design/methodology/approach: To know entrepreneurial intentions and the different variables related to entrepreneurship, a questionnaire previously validated was used. The questionnaire was provided to 578 students pre-graduated (1st-4th course and post-graduate of Physical Activity and Sport Science degree of Valencia. Findings: Statistically significant differences (p ≤ 0.05 in the variables that predict entrepreneurial intention of Physical Activity and Sport Science students by gender and training were found. In both genders, the attitude towards entrepreneurship and the perceived behavior control were the predictors of entrepreneurial intentions and in men also the subjective norms. Research limitations/implications: The students sample belongs only to the Physical Activity and Sport Science degree of Valencia, so the results cannot be extrapolated to the entire population. Practical implications: It should be developing the attitude toward the behavior of entrepreneurship and perceived behavioral control to promote entrepreneurship. In this way, the graduates will be more prepare for insertion into the working world. Social implications: To increase the number of entrepreneurs (male and female in the sports sector throughout the education, reducing the gender gap in entrepreneurship and improve the quality of entrepreneurship, as this is a key issue because of the positive impact that this phenomenon generates on the economy Originality/value: It is interesting to know the predictor variables of entrepreneurial intentions, and to know if there are differences based on education and gender due to the massive entry of women into the sport workplaces and low intention to undertake of the. So it is quite

    Youth participation in organised sport and physical activity is important for healthy development, growth and wellbeing. In 2014, Active Healthy Kids Australia released its inaugural Report Card on Physical Activity for Children and Young People, which synthesised the best available national- and state-level data for children and young people (Sport from the 2014 Report Card, compares Australia's Organised Sport grade with other countries, identifies future directions for research and surveillance, and explores possible beneficial strategies. The Report Card highlighted that between 64% and 85% of Australians aged 5-17 years participate in organised sports, a rate higher than alternate forms of physical activity such as active transportation, active play and school based physical activity. This finding reflects Australia's position as one of the global leaders for participating in organised sport. Future research and surveillance methodologies however, need to incorporate standardised metrics that aim to capture more detailed data regarding organised sport participation. Facilitating access for all children and preventing dropout from organised sports are important initiatives to improve current levels of sport participation. However, given that 80% of Australians aged 5-17 years are not sufficiently physically active to achieve the daily recommendation, participation in sport alone is not enough to ensure that children can accrue the health benefits associated with being physically active. As such, there is a pressing need to develop strategies that engage children in other forms of physical activity such as active transportation and active play.

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

    2017-11-01

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

    Physical activity levels in most affluent countries are low and many people do not meet the current recommendations. Particularly for people with a low income, economic strategies seem promising to stimulate taking part in sports activities. This study investigated the importance of economic restraints for taking part in sports activities as well as perceptions of low-income people toward different pricing interventions. A qualitative study was conducted, using semistructured, individual interviews with 27 low-income men and women. The framework approach was used to analyze the transcripts of the interviews. The respondents considered finances to be an important barrier for participating in sports activities, together with some individual barriers. Promising pricing strategies are a discount on the subscription to the fitness or sports club, a 1 month free trial, and free entrance to the swimming pool once a week. Pricing strategies may be a promising intervention to increase physical activity levels of low-income people. However, this study indicates that this should be coupled with an intervention directed at individual barriers. Some pricing strategies will be used and appreciated more by low-income people than other pricing strategies. In addition, pricing strategies should be tailored to individual needs and preferences.

    Full Text Available Participation in regular moderate aerobic physical activity and increased physical fitness is associated with a decrease in cardiovascular mortality, which is after the age of 35 most often due to coronary events. On the other hand, moderate and vigorous physical exertion is associated with an increased risk for cardiac events, including sudden cardiac death in individuals harbouring cardiovascular disease. The risk-benefit ratio may differ in relation to the individual's age, fitness level and the presence and type of cardiovascular disease.The latest position stand of the European association of Cardiovascular Prevention and Rehabilitation on cardiovascular evaluation in middle aged/senior individuals, who are contemplating exercise or who are already engaged in nonprofessional competitive or recreational leisure sporting activity, is presented in the article. The aim of recommendations is to evaluate and encourage as many individuals as possible to participate in regular physical activity while minimizing the risk of cardiovascular adverse events. Recommendations are based on the individual's risk profile and the intended level of physical activity. Because of the large size of the population, an initial self assessment through health questionaire is proposed, relating to symptoms, risk factors for coronary artery disease and habitual exercise level. For those with positive self-assessed risk profile and those willing to perform high-intensity activities, a further risk stratification/evaluation should be performed by a qualified physician. In individuals with an increased risk for coronary events, maximal exerise is advocated and then further (cardiological evaluation when needed.

To evaluate and classify children and young people as to physical aptitude related to health through scientifically validated indicators and to relate them to socioeconomical condition. To verify compatibility between qualitative and quantitative researches. The sample of the qualitative study is composed of 22 subjects, characterizing itself as a non probabilistic sample of the causal type. Semi structured interview techniques in an individual situation and free evocation of words were used, based on the presuppositions of the Theory of Social Representations. A mixed sample, of the quantitative study, is composed of 67 children, where the possibility of relationship of the family income variable was confirmed with the variables: Body Composition and Flexibility, that compose the physical aptitude indicator related to health and the social representation of the parents. The qualitative results refer to biological aspects of health that constitute the central nucleus of the social representation of sport. In the quantitative aspect, it is verified that there was no correlation statistically, significant between the indexes of physical aptitude and the family income. The reason attributed to the physical-sport activities by the parents or relatives of the children, is based on the benefits to biological health and is shown by the children's good performance in the applied aptitude tests. There is not significant correlation between the index of physical aptitude applied to health, which reinforces the possibility of the parents social representation and the children's behavior.

    Adventure and extreme sports often involve unpredictable and inhospitable environments, high velocities, and stunts. These activities vary widely and include sports like BASE jumping, snowboarding, kayaking, and surfing. Increasing interest and participation in adventure and extreme sports warrants understanding by clinicians to facilitate prevention, identification, and treatment of injuries unique to each sport. This article covers alpine skiing and snowboarding, skateboarding, surfing, bungee jumping, BASE jumping, and whitewater sports with emphasis on epidemiology, demographics, general injury mechanisms, specific injuries, chronic injuries, fatality data, and prevention. Overall, most injuries are related to overuse, trauma, and environmental or microbial exposure. Copyright © 2016 Elsevier Inc. All rights reserved.

    Slowing the decline in participation in physical activity among adolescent girls is a public health priority. This study reports the outcomes from a multi-component school-based intervention (Girls in Sport), focused on promoting physical activity among adolescent girls. Group randomized controlled trial in 24 secondary schools (12 intervention and 12 control). Assessments were conducted at baseline (2009) and at 18 months post-baseline (2010). The setting was secondary schools in urban, regional and rural areas of New South Wales, Australia. All girls in Grade 8 in 2009 who attended these schools were invited to participate in the study (N = 1769). Using a Health Promoting Schools and Action Learning Frameworks, each school formed a committee and developed an action plan for promoting physical activity among Grade 8 girls. The action plan incorporated strategies in three main areas - i) the formal curriculum, ii) school environment, and iii) home/school/community links - based on the results of formative data from target girls and staff and on individual needs of the school. A member of the research team supported each school throughout the intervention. The main outcome measure was accelerometer-derived total physical activity (TPA) spent in physical activity. Data were analyzed from December 2011 to March 2012. 1518 girls (mean age 13.6y ±0.02) were assessed at baseline. There was a significant decline in TPA from baseline to 18-month follow-up with no differences between girls in the intervention and control schools. Only one-third of schools (4/12) implemented the intervention as per their action plan. Per-protocol analyses on these schools revealed a smaller decline in percentage of time spent in MVPA among girls in the intervention group (adjusted difference 0.5%, 95% CI = -0.01, 0.99, P = 0.05). The Girls in Sport intervention was not effective in reducing the decline in physical activity among adolescent girls. Lack of implementation by most

    Full Text Available Tourism that is a regional means of development is closely related with the local economic development. Winter tourism is a set of activities and relationships composed of trips made to the regions which are located in the heart of ski sports and accordingly with slopes and snow, accommodations and other services. Since winter tourism mainly consists of a number of activities depending on snowy environments, it requires locations with certain height and slope which will also allow the execution of other nature sports such as walking, climbing etc. besides skiing and snowboarding. Uludağ, the most popular winter sports center that is 30 km away from the Bursa city center has significant natural advantages in terms of winter tourism. However, with the recently changing tourism demands in winter tourism, developments have been taking place in the types of tourism. Uludağ having natural advantages have not been able to sufficiently benefit from these advantages and cannot make use of its existing potential. Besides the countries having sucessful snow resorts of Europe such as Austria, France, Switzerland, Italy and Andorra, Romania and Bulgaria are also increasing their competitiveness in the international markets in recent years with ambitious investments. When Uludağ that is in the location of the largest snow resort in Turkey is compared with these resorts, it is thought that there is a way to go in the field of winter tourism. Starting from this idea, in the research, it is aimed to identify the contribution of Uludağ to the local economic development and the potentials for increasing this contribution. Towards the mentioned aim, the study will be carried out based on field research. In the conclusion of the study, it is planned to submit the proposals focused on policy and strategy to be followed in terms of having Uludağ use its potential in the most efficient way and provide more contribution to the local economy. In addition, its

    To determine the association between youth sport team participation and dietary behaviors among elementary school-aged children. Cross-sectional survey. Public schools in Texas during 2009-2010. A total of 5035 ethnically diverse fourth graders. Participation in organized sports teams, consumption of select food items (fruits, vegetables, beverages, sweets/snacks). Multiple logistic regression was used to assess the association between each food item (eaten at least once on the previous day) and number of sports teams as the independent class variable (0, 1 ,2, ≥3), adjusting for body mass index physical activity, socioeconomic status, and ethnicity. Significant dose-response associations were observed between number of sports teams and consumption of fruits and vegetables. For boys, the likelihood of eating fruit and fruit-flavored drinks was significantly higher and the odds of drinking soda were lower with the number of teams. For girls, the likelihood of consuming green vegetables increased as sports teams participation increased, and participation was positively associated with diet soda consumption. A positive association was observed between the number of sports teams and scores on the Healthy Food Index for boys and girls. The findings that sports participation is associated with consumption of fruits and vegetables and lower consumption of soda suggest that efforts should be focused on supporting youth team sports to promote healthier food choices. Since sports are available to all ages, sports may be an important venue for promoting healthier dietary behaviors.

    For hibernators, being born late in the active season may have important effects on growth and fattening, hence on winter survival and reproduction. This study investigated differences in growth, fattening, energetic responses, winter survival and fecundity between early-born (‘EB’) and late-born (‘LB’) juvenile garden dormice (Eliomys quercinus). LB juveniles grew and gained mass twice as fast as EB individuals. Torpor use was low during intensive growth, that are, first weeks of body mass gain, but increased during pre-hibernation fattening. LB juveniles showed higher torpor use, reached similar body sizes but lower fat content than EB individuals before hibernation. Finally, LB individuals showed similar patterns of hibernation, but higher proportion of breeders during the following year than EB dormice. These results suggest that torpor is incompatible with growth but promotes fattening and consolidates pre-hibernation fat depots. In garden dormice, being born late in the reproductive season is associated with a fast life history. PMID:29458712

    Video gaming as a therapeutic tool has largely been studied within the stroke population with some benefits reported in upper limb motor performance, balance, coordination, and cardiovascular status. To date, muscle activation of upper limb muscles in persons with spinal cord injuries (SCI) has not been studied during video game play. In this paper, we provide descriptive and comparative data for muscle activation and strength during gaming for players with tetraplegia and paraplegia, as well as, compare these results with data from traditional arm exercises (ie, biceps curl and shoulder press) with light weights which are commonly prescribed for a home program. Fourteen individuals with chronic SCI (9 tetraplegia, 5 paraplegia). We measured upper limb muscle activation with surface electromyography (EMG) during Wii Sports video game play. Muscle activation was recorded from the playing arm during 4 selected games and normalized to a maximum voluntary contraction (MVC). Heart rate and upper limb motion were recorded simultaneously with EMG. Wilcoxon signed rank tests were used to analyze differences in muscle activation between participants with paraplegia versus tetraplegia and compare gaming with traditional arm exercises with light weights. A Friedman 2-way analysis of variance identified key muscle groups active during game play. Overall muscle activation across the games was not different between those with paraplegia and tetraplegia. Heart rate during video game play for tennis and boxing were on average 10 to 20 beats/minute above resting heart rate. The magnitude of EMG was relatively greater for traditional arm exercises with light weights compared with game play. The selected Wii games were able to elicit upper extremity muscle activation and elevated heart rates for individuals with SCI that may be used to target therapeutic outcomes.

    Sport is becoming increasingly more important in our society. Due to the changing age spectrum with a greater number of elderly and substantially more active people, an increasing number of people with underlying orthopedic diseases are becoming interested in participating in sport. This article deals with the possibilities and effects of sporting activities for people with rheumatoid arthritis within the framework of a conservative therapy. A literature search was carried out using medical search engines, in particular PubMed, and also via the recommendations of specialist societies and patient help groups. The quality of life of patients with rheumatoid arthritis consists of physical, mental and social components. Sport as a means of rehabilitation influences all of these components. Sport should be comprehended as a form of therapy and be adapted to the needs of the individual patient. The willingness to actively participate in sport should always be highly rated and encouraged. Sport is therefore an important pillar of therapy in a conservative total concept. The main aspects of sport therapeutic activities are functional, pedagogical and experience-oriented aspects. The clinical symptoms, extent of damage and physical impairment must, however, be evaluated and taken into consideration for the therapeutic concept. The amount of data on the complex topic of sport and rheumatoid arthritis is low and is mainly dealt with as retrospective reviews. A prospective randomized study basis is lacking. The aim must therefore be to confirm the currently available recommendations for various types of sport in controlled studies.

    Winter road maintenance activities are crucial for maintaining the accessibility and traffic safety of the road network at northerly latitudes during winter. Common winter road maintenance activities include snow ploughing and the use of anti-icing agents (e.g. road salt, NaCl).

    The relationship between sport and technology is close and can be both fruitful and destructive. Technology has a constitutive function in sport as it makes the activity possible and it can enhance performance as well as the sporting experience. The use of football boots is clearly more comfortable...... and effective than playing in bare feet in a game of football. However, sport challenges its athletes by demanding the employment of less efficient means rather than more efficient means in pursuit of sport specific goals. Therefore technology can potentially subtract from the sporting experience and even...... has long been a heated topic and with gene technology waiting around the corner the relationship between sport and technology has become strained and is more and more often viewed as problematic rather than benign.

    People with severe psychosocial disabilities have a 20-years shorter lifespan due to chronic somatic comorbidities and the long-term consequences of the side-effects of antipsychotic drugs. They often are sedentary and show lower levels of physical activity, factors which can contribute to their shorter lifespan, because of the greater cardiovascular risk. An increasing amount of evidence, including clinical trials, pointed out that sport, physical activity and structured exercise programs improve physical and psychological wellbeing of people with psychosocial disabilities, playing also an important role against their social isolation and self-stigma. The NICE and APA guidelines include exercise and physical activity for the management of depressive symptoms. Safe and effective programs require multidisciplinary teams that should always include mental health professionals, able to recognize the psychosocial needs, the impact of symptomatology, the role of secondary effects of psychotropic medication, the effect of previous exercise history, the lack of motivation, the inexperience with effort intensity and the frustration of people with psychosocial disabilities.

    2009-10-01

    This study examined the hypothesis that when students received and/or provided either support for skill improvement or support for interpersonal relations, their overall adjustment level in extracurricular activities would be higher than for students who received and/or provided neither support. Data were analyzed from 475 junior high school students (female 175, male 300) who were taking extracurricular sports activities, out of 743 research participants. The results were as follows. Students who received support mainly for skill improvement showed a statistically equivalent adjustment level as students who received support mainly for interpersonal relations. Students who received either support showed higher adjustment levels than students who received neither. Additionally, providing support showed the same results. The exchange of different types of social support showed equivalent effects on the adjustment level as the exchange of the same type of social support. These results suggest that even though the types of social support are different for skill improvement or interpersonal relations, the exchange of support positively contributes to junior high school students' adjustment level in extracurricular activities.

    Based on research on stereotype threat and multiple identities, this work explores the beneficial effects of activating a positive social identity when a negative identity is salient on women's performance in sports. Further, in line with research on the effects of anxiety in sports, we investigate whether the activation of a positive social identity buffers performance from cognitive anxiety associated with a negative stereotype. Two experiments tested these predictions in field settings. Experiment 1 (N = 83) shows that the simultaneous activation of a positive (i.e., member of a soccer team) and a negative social identity (i.e., woman) led to better performance than the activation of only a negative social identity for female soccer players. Experiment 2 (N = 46) demonstrates that identity condition moderated the effect of cognitive anxiety on performance for female basketball players. Results are discussed concerning multiple identities' potential for dealing with stressful situations.

    Eye injuries sustained during sport comprise up to 20 per cent of all injuries to the eye serious enough for medical attention to be sought. The prevalence of eye injuries in sport is not easily assessed due to lack of authoritative participation rates, so most studies report total numbers in a time period. The evidence on the proportion of all ocular injuries that are from sport is reviewed. The relative frequencies in different sports are compared in a qualitative manner and the sports with greater numbers of ocular injuries are detailed. In common with occupational injuries to the eye, most sports eye injuries are considered preventable. The hierarchy of action for occupational risk is detailed and adapted to use in a sports scenario. All the available international, regional and national standards on sports eye protection are detailed and their provisions compared. The major function of the standards is to provide adequate protection against the hazard of the sport concerned. These are detailed and compared as a function of energy transfer. Eye protection must not introduce additional or secondary hazards (for instance, fracturing into sharp fragments on impact) and not introduce features that would deter the wearing of eye protection (for instance, restricting field of view to impede playing the sport). The provisions of the standards intended to limit secondary hazards are detailed and compared. The need for future work in standards writing and the activities of the International Standardization Organization in sports eye protection are detailed. © 2016 Optometry Australia.

    In many sports, maintaining balance is necessary to compete at a high level. Also, in many health problems, balance is impaired. Postural sway (PS) is often used as an indicator of upright balance control, and physical activity (PA) might enhance balance control. However, the relationship between PS and PA has never been systematically reviewed. Our objective was to summarize the evidence regarding the relationship between PS in upright bipedal and unipedal standing and PA. We conducted a literature search in MEDLINE, EmBase, CINAHL, the Cochrane Database, and PEDro, up to March 2012, with no limit on the starting date. Characteristics and methodological aspects of each article were extracted by two reviewers. We used centre of pressure (CoP) velocity, and variables related to the CoP area, to compare studies. A total of 39 articles were reviewed from an initial yield of 2,058. Of these 39 studies, 37 used a comparative design, one was a cohort study, and one was a randomized controlled trial. The main conclusion was that in general, sport practitioners sway less than controls, and high-level athletes sway less than low-level athletes. Additionally, we identified specific effects dependent on the use of vision, sport-specific postures, and frequency and duration of the (sports) activity. PS in unperturbed bipedal stance appears to have limited sensitivity to detect subtle differences between groups of healthy people.

    Youth sport (YS) reaches a large number of children world-wide and contributes substantially to children's daily physical activity (PA), yet less than half of YS time has been shown to be spent in moderate-to-vigorous physical activity (MVPA). Physical activity during practice is likely to vary depending on practice structure that changes across YS time, therefore the purpose of this study was 1) to describe the type and frequency of segments of time, defined by contextual characteristics of practice structure, during YS practices and 2) determine the influence of these segments on PA. Research assistants video-recorded the full duration of 28 practices from 14 boys' flag football teams (2 practices/team) while children concurrently (N = 111, aged 5-11 years, mean 7.9 ± 1.2 years) wore ActiGraph GT1M accelerometers to measure PA. Observers divided videos of each practice into continuous context time segments (N = 204; mean-segments-per-practice = 7.3, SD = 2.5) using start/stop points defined by change in context characteristics, and assigned a value for task (e.g., management, gameplay, etc.), member arrangement (e.g., small group, whole group, etc.), and setting demand (i.e., fosters participation, fosters exclusion). Segments were then paired with accelerometer data. Data were analyzed using a multilevel model with segment as unit of analysis. Whole practices averaged 34 ± 2.4% of time spent in MVPA. Free-play (51.5 ± 5.5%), gameplay (53.6 ± 3.7%), and warm-up (53.9 ± 3.6%) segments had greater percentage of time (%time) in MVPA compared to fitness (36.8 ± 4.4%) segments (p ≤ .01). Greater %time was spent in MVPA during free-play segments compared to scrimmage (30.2 ± 4.6%), strategy (30.6 ± 3.2%), and sport-skill (31.6 ± 3.1%) segments (p ≤ .01), and in segments that fostered participation (36.1 ± 2.7%) than segments that fostered exclusion (29.1 ± 3.0%; p ≤ .01

    Full Text Available In the Arctic polar vortex of the 2009/10 winter temperatures were low enough to allow widespread formation of polar stratospheric clouds (PSCs. These clouds occurred during the initial chlorine activation phase which provided the opportunity to investigate the impact of PSCs on chlorine activation. Satellite observations of gas-phase species and PSCs are used in combination with trajectory modeling to assess this initial activation. The initial activation occurred in association with the formation of PSCs over the east coast of Greenland at the beginning of January 2010. Although this area of PSCs covered only a small portion of the vortex, it was responsible for almost the entire initial activation of chlorine vortex wide. Observations show HCl (hydrochloric acid mixing ratios decreased rapidly in and downstream of this region. Trajectory calculations and simplified heterogeneous chemistry modeling confirmed that the initial chlorine activation continued until ClONO2 (chlorine nitrate was completely depleted and the activated air masses were advected throughout the polar vortex. For the calculation of heterogeneous reaction rates, surface area density is estimated from backscatter observations. Modeled heterogeneous reaction rates along trajectories intersecting with the PSCs indicate that the initial phase of chlorine activation occurred in just a few hours. These calculations also indicate that chlorine activation on the binary background aerosol is significantly slower than on the PSC particles and the observed chlorine activation can only be explained by an increase in surface area density due to PSC formation. Furthermore, there is a strong correlation between the magnitude of the observed HCl depletion and PSC surface area density.

    Leisure sports activities are assumed to be safe. It is however possible that participation in contact sports as leisure activity may also affect the space available for the cervical cord (SAC). The objective of this study is to compare the SAC of asymptomatic young adults involved in active leisure contact sports with matched controls that do not participate in contact sports. This magnetic resonance imaging-based prospective, cross-sectional study involved 204 randomly selected asymptomatic adults, 21-50 years of age. The study included 2 groups: group A (participants in active leisure contact sports) and group B (participants who did not participate in any form of contact sport). The SAC was calculated by subtracting disk-level midsagittal spinal canal dimension from the corresponding level spinal cord dimension. The SAC at C3-4 was 4.5 ± 1.1 mm (group A) and 4.9 ± 1.4 mm (group B) (P = 0.025), at C4-5 was 4.3 ± 1.1 mm (group A) and 4.5 ± 1.2 mm (group B), at C5-6 was 4.6 ± 1.1 mm (group A) and 4.5 ± 1.4 mm (group B), at C6-7 was 5.2 ± 1.3 mm (group A) and 4.9 ± 1.2 mm (group B), at C7-T1 was 5.6 ± 1.3 mm (group A) and 5.6 ± 1.5 mm (group B) (P = 0.004). In men, the SAC at C3-4 was 4.39 ± 0.28 mm (group A) and 4.90 ± 0.30 mm (group B) (P = 0.036) and at C4-5 was 4.16 ± 0.27 mm (group A) and 4.56 ± 0.35 mm (group B). Three-way multivariate analysis of variance revealed significant effect of contact sports (P = 0.005), sex (P = 0.001), and age (P = 0.0001) on the SAC. Combined effect of contact sports participation and age also have significant effects on the SAC (P = 0.035). Participation in leisure contact sports has a small but overall negative effect on the SAC, especially at the upper subaxial cervical spine levels. This effect is most marked after the age of 40 years. Overall, there was no sex difference observed. Copyright © 2017 Elsevier Inc. All rights reserved.

    The purpose of this study was to explore adolescents' perceptions of psychosocial influences - personal characteristics, environmental factors and behavioural undertakings - influencing their prolonged involvement in sports and physical activity (PA). A qualitative approach was adopted wherein 16 adolescents (8 boys, 8 girls; mean age 15.9 years), who had been physically active for at least the last 8 years, and sixteen adults identified as their 'parents' or 'guardians' participated in semi-structured interviews. Interviews were transcribed verbatim and coded using the HyperRESEARCH software. Data were analysed using thematic analysis procedures. Four main themes pertaining to psychosocial influences were identified: 1) personal characteristics; 2) school and community resources; 3) parental support; and 4) social interaction. Except for social interaction, for which participants did not identify challenges, themes are discussed according to their motivational aspects and the challenges they represent for adolescents' PA involvement. The research has implications for health promotion endeavours directed toward parents of children and adolescents. Given the limitations of a qualitative study, readers are invited to apply the conclusions to their own context.

    2017-05-01

    Full Text Available Given the dramatic demographic change underway in most industrialized nations, the health of older adults is a major concern, particularly given the prevalence of sedentary behaviours and physical inactivity among ageing populations. Researchers have suggested sport participation in later life promotes other health-related behaviours, however, these relationships are poorly understood. It is possible for individuals to be classified as sufficiently active and still spend most of their day involved in sedentary pursuits. Moreover, there is little information on older sport participants’ use of time compared to leisurely active or inactive peers and whether type of physical activity involvement is associated with differences in older adults’ behaviour patterns. With this in mind, data from 1,723 respondents (65 years and older who completed the sport module of the 2010 Canadian General Social Survey–Time Use were used to investigate the influence of physical activity involvement (competitive sport vs. non-competitive sport vs. physically active leisure vs. inactivity on time spent in leisure-time physical activity and sedentary behaviours. Results indicated that competitive sport participants spent less time engaging in sedentary behaviours compared to the physically active leisure or inactive respondents; however, sport participants (both competitive and non-competitive also spent less time engaging in leisure-time physical activities than the physically active leisure group. Implications of these findings to assumptions related to the activity levels of older sport participants, suggestions for future research, and considerations for sport-related interventions aimed at enhancing health in older adulthood are discussed.

    Full Text Available In contemporary tourism, sport and recreation are increasingly becoming the dominant motives for undertaking the journey, and as a result of modern living, active holidays are more frequent. Mountain areas have always been attractive to deal with the various sports activities. Winter sports were the initiators of the development of mountain resorts. Mountain resorts invest in construction of hotels, ski lifts, snowmaking equipment, for the sake of attracting a growing number of tourist clientele. On the other hand, sport and recreation also serve to promote summer mountain tourism. Tennis, golf, swimming, horseback riding are key tools to attract visitors in the summer months toward the resorts facilities. The main problems regarding the development of mountain tourism centers come in the form of the growing concern for the preservation of the environment, of the human and traffic congestion in the mountains and the intensive use of natural resources by tourists. This paper aims to highlight the positive and negative impacts of sport and recreation in the development of mountain tourism and to present possible solutions to reduce negative impacts. Methodology is based on document review of many bibliographic resources, which are related with skiing and mountain biking as examples of winter and summer sport activities on mountains.

    Young patients feel that maintaining sport activities after total hip arthroplasty constitutes an important part of their quality of life. The majority of hip surgeons allow patients to return to low-impact activities, but significant caution is advised to taking part in high-impact activities. The purpose of this study is to compare and evaluate the post-operative return to daily living habits and sport activities following short-metaphyseal hip and high functional total hip arthroplasties (resurfacing and big femoral head arthroplasties). In a study design, 48 patients (55 hips) were enrolled in three different comparative groups, one with the short-metaphyseal arthroplasties, a second with high functional resurfacing arthroplasties and a third of big femoral head arthroplasties. Each patient experienced a clinical examination and evaluated with Harris Hip Score, WOMAC, Sf-36, UCLA activity score, satisfaction VAS, anteroposterior and lateral X-rays of the hip and were followed in an outpatient setting for 2 years. Statistical analysis revealed no notable differences between the three groups regarding their demographic data however significant differences have been found between preoperative and postoperative clinical scores of each group. Also, we fail to reveal any significant differences when comparing data of all three groups at the final 2 years postoperative control regarding their clinical scores. The overall outcome of all three groups was similar, all the patients were satisfied and returned to previous level of sport activities. Short metaphyseal hip arthroplasties in young patients intending to return to previous and even high impact sport activities, similar to high functional resurfacing, big femoral head arthroplasties. Short stems with hard on hard bearing surfaces might become an alternative to standard stems and hip resurfacing.

    Spinal injuries are very common among professional or amateur athletes. Spinal sport lesions can be classified in overuse and acute injuries. Overuse injuries can be found after years of repetitive spinal load during sport activity; however specific overuse injuries can also be found in adolescents. Acute traumas are common in contact sports. Most of the acute injuries are minor and self-healing, but severe and catastrophic events are possible. The aim of this article is to review the wide spectrum of spinal injuries related to sport activity, with special regard to imaging finding.

    2013-09-01

    The benefits of regular physical activity have been known since ancient Greek. But in the last Century the scientific knowledge around this topic has progressed enormously, starting with the early studies of JN Morris and RS Paffenberger, who demonstrated that physical activity at work reduced incidence of cardiovascular disease and mortality. In the Harvard alumni study, the lowest risk was associated with a weekly output of 1000 to 2000 kcal performing vigorous activities. Further studies in all age groups have supported these findings and have added that even moderate levels of physical activity provide considerable benefits to health, including lower prevalence of overweight and obesity at all ages. Metabolic fat oxidation rate is highest at exercise intensities between 45 and 65% of VO2max. This means that people must be active regularly and force physiological mechanisms at certain intensities. All this body of evidence has contributed to current WHO physical activity recommendations of 150 min/week of moderate to vigorous physical activity (MVPA) in adults and elderly, and 60 min/day of MVPA in children and adolescents, with additional strength training, apart from adopting an active lifestyle. In the last 50 years, occupational physical activity has been reduced for about 120 kcal/day, and sedentarism has emerged as an additional risk factor to physical inactivity. Even if less than 60 min of TV time in adults have been related to lower average BMI, there is still a need for research to determine the appropriate dose of exercise in combination with sedentary behaviours and other activities in the context of our modern lifestyle in order to prevent obesity at all ages. As public health measures have failed to stop the obesity epidemic in the last 3 decades, there is clearly a need to change the paradigm. The inclusion of sport scientists, physical education teachers and other professionals in the multidisciplinary team which should be responsible for drawing

    To determine whether regular performance of adapted sports is associated with long-term changes in carotid atherosclerosis in subjects with spinal cord injury (SCI). Prospective observational study. Academic medical center. Men with chronic (>1y) SCI and no preserved motor function below the injury level were evaluated in 2007 and 2012 (N=17). Nine subjects did not perform physical activity between the studied time points (control group), whereas 8 subjects entered competitive upper-body sports programs (rugby: n=5, basketball: n=1, jiu-jitsu: n=1, and tennis: n=1) after baseline and were regularly training at the time of the second evaluation (sports group). Not applicable. Clinical, laboratory, hemodynamic, and carotid ultrasonography analysis. The studied groups showed no differences in all studied variables at baseline. After 5 years of follow-up, the control group showed increases in heart rate (87.0±3.1 vs 74.7±3.8 beats per minute; P=.004), but the participants had no significant changes in carotid intima-media thickness (IMT) (.65±.05 vs .67±.03mm; P=.73) or IMT/diameter (.118±.007 vs .136±.013; P=.24). In contrast, the sports group showed long-term decreases in carotid IMT (.56±.05 vs .74±.05mm; P=.001) and IMT/diameter (.097±.006 vs .141±.009; P<.001), but the participants did not show any variation in the other studied variables at follow-up. Regular upper-body sports activities are associated with long-term reductions in carotid atherosclerosis in subjects with SCI and might be a potential prevention strategy aiming to reduce cardiovascular risk in this population.

    In this paper, the effects of different nitrogen application rates on the nitrate reductase (NR) activity, nitric oxide (NO) content and gas exchange parameters in winter wheat (Triticum aestivum L.) leaves from tillering stage to heading stage and on grain yield were studied. The results showed that the photosynthetic rate (P(n)), transpiration rate (T(r)) and instantaneous water use efficiency (IWUE) of leaves as well as the grain yield were increased with increasing nitrogen application rate first but decreased then, with the values of all these parameters reached the highest in treatment N180. The NR activity increased with increasing nitrogen application rate, and there was a significant linear correlation between NR activity and NO content at tillering and jointing stages (R2 > or = 0.68, n = 15). NO content had a quadratic positive correlation with stomatal conductance (G(s)) (R2 > or = 0.43, n = 15). The lower NO content produced by lower NR activity under lower nitrogen application rate promoted the stoma opened, while the higher NO content produced by higher NR activity under higher nitrogen application rate induced the stoma closed. Although the leaf NO content had a quadratic positive correlation with stomatal conductance (R2 > or = 0.36, n = 15), no remarkable correlation was observed between NR activity and NO content at heading stage, suggesting that nitrogen fertilization could not affect leaf NO content through promoting NR activity, and further more, regulate the stomatal action. Under appropriate nitrogen application the leaf NR activity and NO content were lower, G(s), T(r) and IWUE were higher, and thus, the crop had a better drought-resistant ability, higher P(n), and higher grain yield.

    Full Text Available Abstract Background Physical inactivity has become a major public health problem and clear educational differences in physical activity have been reported across Europe and USA. The origins of adulthood physical activity are suggested to be in childhood and adolescence physical activity. Hardly any studies have, however, examined if the educational differences in physical activity might also be due to educational differences in early experiences in physical activity. Thus, our aim was to examine how competitive sports in youth, and exercise in late adolescence, and opinions on physical education (PE in childhood determined adulthood leisure-time physical activity (LTPA in different educational groups. Methods We used cross-sectional population-based National FINRISK 2002 data for 1918 men and 2490 women aged 25 to 64 years. Competitive sports in youth, exercise in late adolescence, and opinions on PE in childhood were assessed retrospectively via self-reports. Adulthood LTPA was collected with 12-month recall. In 2008, we calculated structural equation models including latent variables among the low- ( Results Men more often than women reported that their experience of PE was interesting and pleasant as well as having learned useful skills during PE classes. Men, compared to women, had also been more active in the three selected competitive sports in youth and exercised in late adolescence. Participation in competitive sports in youth among the low-educated and exercise in late adolescence among the high-educated had a direct effect on adulthood LTPA. Among the low-educated, opinions on PE in childhood had an indirect effect on adulthood LTPA through participation in competitive sports in youth whereas among the high-educated, the indirect effect went through exercise in late adolescence. The effects were mainly similar between genders. Conclusions Our study answers to a strong need to assess the determinants of leisure-time physical activity to

    In the eastern United States, winter temperature has been increasing nearly twice as fast as summer temperature, but studies of warming effects on plants have focused on species that are photosynthetically active in summer. The terrestrial orchid Tipularia discolor is leafless in summer and acquires C primarily in winter. The optimum temperature for photosynthesis in T. discolor is higher than the maximum temperature throughout most of its growing season, and therefore growth can be expected to increase with warming. Contrary to this hypothesis, experimental warming negatively affected reproductive fitness (number of flowering stalks, flowers, fruits) and growth (change in leaf area from 2010 to 2012) in T. discolor. Temperature in June-July was critical for flowering, and mean July temperature greater than 29 °C (i.e., 2.5 °C above ambient) eliminated reproduction. Warming of 1.2 °C delayed flowering by an average of 10 days and fruiting by an average of 5 days. Warming of 4.4 °C reduced relative growth rates by about 60%, which may have been partially caused by the direct effects of temperature on photosynthesis and respiration. Warming indirectly increased vapor pressure deficit (VPD) by 0.2-0.5 kPa, and leaf-to-air VPD over 1.3 kPa restricted stomatal conductance of T. discolor to 10-40% of maximum conductance. These results highlight the need to account for changes in VPD when estimating temperature responses of plant species under future warming scenarios. Increasing temperature in the future will likely be an important limiting factor to the distribution of T. discolor, especially along the southern edge of its range.

    Aim of this study was to investigate the sedentary patterns of school-aged active children admitted to a summer sport school. One hundred-twelve children aged 9-11 years were interviewed through a questionnaire about sedentary behaviours and nutrition habits. Seventy-one per cent of children reported they watch TV seven days a week, girls less than boys (84 +/- 45 minutes vs. 110 +/- 75 minutes) (t = 2.056; p = 0.042). The habit of TV viewing during meals was widespread (38% breakfast, 31% lunch, 62% dinner, 18% every meal). The prevalence of overweight or obesity (58.5%) was significantly higher among boys watching TV at dinner compared to the boys viewing TV only in the afternoon (35%) (chi2 = 4.976; p = 0.026). Fifty-seven per cent of children (65% boys) were accustomed to nibble snacks during TV viewing, and this habit was widespread in overweight or obese boys (chi2 = 4.546; p = 0.033). The dietary patterns of children watching TV include more snack foods and fewer fruits than the dietary patterns of the same children exercising (chi2 = 4.199 p = 0.040). Also in active children the habit to watch television is widespread and, in spite of the tendency to physical activity, 46% of them were overweight or obese; in fact the time spent looking at a TV may be associated to overweight/obesity and this relationship could be explained by the amount of high-density foods consumption during inactivity. Playing video games, read a book and listening to music are sedentary lifestyle patterns but these seem not to represent a risk factor for an increased BMI.

    Children participate in four main types of physical activity: organized sport, active travel, outdoor active play, and curriculum-based physical activity. The objective of this study was to develop a valid approach that can be used to concurrently measure time spent in each of these types of physical activity. Two samples (sample 1: n = 50; sample 2: n = 83) of children aged 10-13 wore an accelerometer and a GPS watch continuously over 7 days. They also completed a log where they recorded the start and end times of organized sport sessions. Sample 1 also completed an outdoor time log where they recorded the times they went outdoors and a description of the outdoor activity. Sample 2 also completed a curriculum log where they recorded times they participated in physical activity (e.g., physical education) during class time. We describe the development of a measurement approach that can be used to concurrently assess the time children spend participating in specific types of physical activity. The approach uses a combination of data from accelerometers, GPS, and activity logs and relies on merging and then processing these data using several manual (e.g., data checks and cleaning) and automated (e.g., algorithms) procedures. In the new measurement approach time spent in organized sport is estimated using the activity log. Time spent in active travel is estimated using an existing algorithm that uses GPS data. Time spent in outdoor active play is estimated using an algorithm (with a sensitivity and specificity of 85%) that was developed using data collected in sample 1 and which uses all of the data sources. Time spent in curriculum-based physical activity is estimated using an algorithm (with a sensitivity of 78% and specificity of 92%) that was developed using data collected in sample 2 and which uses accelerometer data collected during class time. There was evidence of excellent intra- and inter-rater reliability of the estimates for all of these types of

    To study the effect of a teachers' ban on supervising sports-related extracurricular physical activities (ECAs), levels of physical activity among 979 grade 7 students (mean age=12.7 [0.5] years at baseline) were compared during and after the ban in seven schools that fully implemented the ban, and three schools that did not implement the ban fully. On average, schools offered 18.0 (SD=5.1) ECAs during a no-ban school year. Students attending full implementation schools were significantly more likely than students in nonimplementation schools to be active after the ban ended (odds ratio for being active=1.89 [95% confidence interval: 1.39, 2.58]). They also increased the number of physical activities in which they participated (coefficient=4.04; SE=1.01). Ending a teachers' ban on sports-related ECAs was associated with increased involvement in physical activity among secondary school students.

    The present study aimed to investigate the longitudinal influence of physical education classes, extracurricular sports activities, and leisure satisfaction on aggressive behavior among South Korean adolescents. Data were drawn from the Korea Youth Panel Survey. We used latent growth curve modeling to explain the growth trajectory of adolescent aggressive behaviors and a multi-group analysis to investigate gender differences in aggressive behavior. The results indicated that adolescents' aggressive behavior significantly changed with age. There were significant gender-based differences in the level of and changes in aggressive behavior over time. Both extracurricular sports activities and leisure satisfaction had significant influences on the changes in adolescents' aggressive behavior with age, whereas physical education classes did not.

    We analyzed the effects of 1 year of engagement in ≥ 300 min/week of organized sports on inflammatory levels and vascular structure in adolescents. The sample was composed of 89 adolescents (11.6 ± 0.7 years old [43 boys and 46 girls]), stratified according to engagement in ≥ 300 min/week of sport practice during at least 12 months of follow-up (n = 15, sport practice; n = 74, non-sport practice). Arterial thickness (carotid and femoral) was assessed by ultrasound scan, while high sensitive C-reactive protein levels were used to assess inflammatory status. Trunk fatness (densitometry scanner), biological maturation (age at peak height velocity), blood pressure, and skipping breakfast were treated as covariates. Independently of body fatness and biological maturation, the group engaged in sports presented a higher reduction in C-reactive protein (mean difference -1.559 mg/L [95%CI -2.539 to -0.579]) than the non-sport group (mean difference -0.414 mg/L [95%CI -0.846 to 0.017]) (p = 0.040). There was a significant relationship between changes in C-reactive protein and changes in femoral intima-media thickness in the non-sport group (r = 0.311 [95%CI 0.026 to 0.549]). Inflammation decreased in adolescents engaged in organized sports, independently of trunk fatness and biological maturation. Moreover, inflammation was related to arterial thickening only in adolescents not engaged in sports. What is Known: • Intima media thickness is a relevant marker of cardiovascular disease in pediatric groups, being affected by obesity and inflammation. • The importance of monitoring inflammatory markers from childhood is enhanced by the fact that alterations in these inflammatory markers in early life predict inflammation and alterations in carotid IMT in adulthood. What is New: • Anti-inflammatory properties related to physical exercise performed at moderate intensity, on inflammation and alterations in IMT are not clear in pediatric

    The purpose of this study was to examine the associations between physical education (PE) and sports involvement with physical activity (PA), physical fitness, and beliefs about PA among a national sample of adolescents. Data from the National Health and Nutrition Examination Survey National Youth Fitness Survey were used. A total of 459 adolescents aged 12 to 15 years. Adolescents self-reported engagement in the above parameters; muscular fitness objectively determined. Multivariable linear regression. Adolescents who had PE during school days had a higher enjoyment of participating in PE (β = 0.32; P = .01), engaged in more days of being physically active for ≥60 min/d (β = 1.02; P fitness test longer (β = 17.2; P = .002). Adolescents who played school sports reported that more PA was needed for good health (β = 0.23; P = .04), had a higher enjoyment of participating in PE (β = 0.31; P = .003), engaged in more days of being physically active for ≥60 min/d (β = 0.70; P = .01), performed more pull-ups (β = 2.33; P = .008), had a stronger grip strength (β = 2.5; P = .01), and performed the plank fitness test longer (β = 11.6; P = .04). Adolescents who had PE during school, who had more frequent and long-lasting PE, and who played school sports generally had more accurate perceptions of the amount of PA needed for good health, had greater enjoyment of PE, were more physically active, and performed better on several muscular fitness-related tests. This underscores the importance of PE integration in the schools and encouragement of school sports participation.

    There is a limited amount of home advantage research concerned with winter sports. There is also a distinct lack of studies that investigate home advantage in the context of para sport events. This paper addresses this gap in the knowledge by examining home advantage in the Winter Paralympic Games. Using a standardised measure of success, we compared the performances of host nations at home with their own performances away from home between 1976 and 2014. Both country level and individual sport level analysis is conducted for this time period. Comparisons are also drawn with the Winter Olympic Games since 1992, the point from which both the Winter Olympic Games and the Winter Paralympic Games have been hosted by the same nations and in the same years. Clear evidence of a home advantage effect in the Winter Paralympic Games was found at country level. When examining individual sports, only alpine skiing and cross country skiing returned a significant home advantage effect. When comparing home advantage in the Winter Paralympic Games with the Winter Olympic Games for the last seven host nations (1992-2014), we found that home advantage was generally more pronounced (although not a statistically significant difference) in the case of the former. The causes of home advantage in the Winter Paralympic Games are unclear and should be investigated further.

  14. Increasing girls’ physical activity during an organised youth sport basketball program: a randomised controlled trial protocol

    Science.gov (United States)

    2014-01-01

    Background Participation in organised youth sports (OYS) has been recommended as an opportunity to increase young peoples’ moderate-to-vigorous physical activity (MVPA) levels. Participants, however, spend a considerable proportion of time during OYS inactive. The purpose of this study, therefore, was to investigate whether coaches who attended coach education sessions (where education on increasing MVPA and decreasing inactivity during training was delivered) can increase players’ MVPA during training sessions over a 5-day basketball program compared to coaches who did not receive coach education sessions. Methods/design A convenience sample of 80 female players and 8 coaches were recruited into the UWS School Holiday Basketball Program in Greater Western Sydney, Australia. A two-arm, parallel-group randomised controlled trial was employed to investigate whether coaches who attended 2 coach education sessions (compared with a no-treatment control) can increase their players’ MVPA during training sessions over a 5-day basketball program. Objectively measured physical activity, directly observed lesson context and leader behaviour, player motivation, players’ perceived autonomy support, and coaching information (regarding training session planning, estimations on player physical activity and lesson context during training, perceived ability to modify training sessions, perceived importance of physical activity during training, intention to increase physical activity/reduce inactivity, and likelihood of increasing physical activity/reducing inactivity) were assessed at baseline (day 1) and at follow-up (day 5). Linear mixed models will be used to analyse between arm differences in changes from baseline to follow-up on all outcomes. Discussion The current trial protocol describes, to our knowledge, the first trial conducted in an OYS context to investigate the efficacy of an intervention, relative to a control, in increasing MVPA. This study’s findings will

    Post-operative infection after arthroscopically assisted anterior cruciate ligament (ACL) reconstruction is a rare but severe complication, particularly for young and active patients. It is unclear whether the prevalence of knee infection is correlated with the type of sports or the level of performance. From 2008 to 2012, the internal single-centre ACL registry of the FIFA Medical Centre of Excellence Regensburg was retrospectively screened for sex, age, time between isolated primary ACL rupture and surgery, surgical technique, rate of infection after ACL reconstruction and the type of sports practised. In total, 4801 ACL reconstructions had been conducted over 5 years, 4579 in amateur and 221 in professional athletes. After application of the exclusion criteria, 1809 athletes with ACL reconstruction were analysed regarding postsurgical infection and the type of sports practised. Professionals and amateurs did not significantly differ with regard to infection rates (n.s.) but in the timing of ACL repair (p sports (n.s.). Staphylococcus aureus and epidermidis were the predominant detected bacteria. All patients were hospitalised and successfully treated with arthroscopic lavage and antibiotic medication. ACL infections showed sports-related differences. Athletes practising summer outdoor sports such as football had a significantly higher risk of infection after ACL reconstruction than winter sports athletes. No difference was found between professional and amateur athletes. Relevant prevention strategies for postsurgical ACL infections should consider influencing patient factors such as the type of sports activity and attendant circumstances. III.

  17. Sport and male sexuality.

    2017-09-01

    The relationships between sport and sexuality in males are of great social and clinical interest, because of sports and motor activities that highly promote social and sexual relationships. Even if few literature exist, two main questions should be taken into account: whether and how physical exercise and sport positively or negatively influence sexual health and behavior and/or whether and how sexual behavior may affect a sub-sequent sport performance. Physical exercise and sport per se can influence, positively or negatively, the hypothalamic-pituitary-testicular axis function and, consequently, the individual's reproductive and/or sexual health. This depends on individual factors such as genetic and epigenetic ones and on different variables involved in the practice of sport activities (type of sport, intensity and duration of training, doping and drug use and abuse, nutrition, supplements, psychological stress, allostatic load, etc.). If well conducted, motor and sport activities could have beneficial effects on sexual health in males. Among different lifestyle changes, influencing sexual health, regular physical activity is fundamental to antagonize the onset of erectile dysfunction (ED). However, competitive sport can lead both reproductive and/or sexual tract damages and dysfunctions, transient (genital pain, hypoesthesia of the genitalia, hypogonadism, DE, altered sexual drive, etc.) or permanent (hypogonadism, DE, etc.), by acting directly (traumas of the external genitalia, saddle-related disorders in cyclists, etc.) or indirectly (exercise-related hypogonadism, drug abuse, doping, stress, etc.). Sexual activities shortly performed before a sport competition could differently influence sport performance. Due to the few existing data, it is advisable to avoid an absolute pre-competition sexual abstinence.

  18. Sport-related concussions

    Jéssica Natuline Ianof

    Full Text Available ABSTRACT Traumatic brain injury (TBI is a major cause of lifelong disability and death worldwide. Sport-related traumatic brain injury is an important public health concern. The purpose of this review was to highlight the importance of sport-related concussions. Concussion refers to a transient alteration in consciousness induced by external biomechanical forces transmitted directly or indirectly to the brain. It is a common, although most likely underreported, condition. Contact sports such as American football, rugby, soccer, boxing, basketball and hockey are associated with a relatively high prevalence of concussion. Various factors may be associated with a greater risk of sport-related concussion, such as age, sex, sport played, level of sport played and equipment used. Physical complaints (headache, fatigue, dizziness, behavioral changes (depression, anxiety, irritability and cognitive impairment are very common after a concussion. The risk of premature return to activities includes the prolongation of post-concussive symptoms and increased risk of concussion recurrence.

    Surface EMG (SEMG) has been used frequently to study motion techniques or skills, body positions, material or equipment used, training-methodology and learning processes in sports and ergonomics. Little if any information is available on the effect of the geographical environment on the neuromuscular control of an athlete or workman during his/her performance or effort. Motions were chosen in Alpine skiing and cycling. Thirty-one certified ski instructors and twelve professional road cyclists participated in the study of geographical variance and its impact on muscle activity. SEMG was measured from the agonists and antagonists of the upper- and lower limb. Skiers were measured on downhill slopes ranging from 19 to 51% while the cyclists performed with different saddle positions on 2, 7 and 12% slope inclinations, respectively. Verification of the variation of muscular intensity (IEMG) over the slope inclination during a simulated giant slalom indicated that the muscular activity increased with increasing slope angle and decreased with decreasing slope angle, while heart rate measured with short-range radio telemetry increased at a constant rate between start and finish independent of the geographical variations. In a direct descent on different slopes % levels the integrated EMG is well related to the inclination (r=0.82) confirming the findings of the giant slalom. In cycling we found that, regardless of the pelvis position, the muscular intensity of lower limb muscles increased with increasing slope inclination, while the muscular intensity of the arms decreased with the same increasing slope inclination. In addition the decreased intensity of the arm muscles remained significantly higher with the pelvis (saddle) fully forward. The geography of the terrain did influence the neuromuscular work and therewith probably the performance also. The influence however, varies with specific circumstances and is coupled with items of variability of the equipment used and

    To investigate the association between the time of day of sports-related physical activity and the onset of acute myocardial infarction (AMI) in a coronary artery disease (CAD) population in China. Between February 2014 and March 2015, a total of 696 patients from Nanjing, China, who had CAD were studied and divided into two groups (Non-AMI and AMI groups). The work-related activity and sports-related physical activity information were obtained from a self-reporting predesigned patient questionnaire. Sports-related physical activity was associated with a lower risk of the onset of AMI, after adjusting the established and potential confounders, with an adjusted odds ratio (OR) of 0.67 (95% CI, 0.47-0.94) compared with those who did not have any sports-related physical activity. A dose-response relationship was observed for intensity, duration, and frequency of sports-related physical activity. Further stratification analysis revealed that the protective effects of sports-related physical activity were significant in the morning and evening groups, and patients who exercised in the evening were at a lower risk of AMI than those doing sports-related physical activity in the morning. The adjusted ORs for doing sports-related physical activity in the morning and evening groups were 0.60(0.36-0.98) and 0.56(0.37-0.87), respectively, compared with inactivity (all Psports-related physical activity in the evening had an adjusted OR of 0.93 (95% CI, 0.54-1.64, P = 0.824) compared with in the morning group. Sports-related physical activity is associated with a lower risk of onset of AMI than inactivity in Chinese people. For CAD patients, we suggest they participate in sports-related physical activity of high intensity, long duration, and high frequency. Doing sports-related physical activity in the evening and in the morning have similar benefits on the prevention of the onset of AMI.

    The health benefits of physical activity are widely established, including decreased risk for disease and improved mental well-being. Yet many children, adolescents, and adults do not meet the minimum recommendations specified in current public health guidelines and physical activity is known to decrease during the life course. The aim of this study was to identify background or personality characteristics that predict whether a healthy 25 year-old would become a physically active 75 year-old. This could have powerful implications for targeting physical activity and health interventions. A unique data set was collected of 712 healthy United States males who passed a rigorous physical exam in the 1940s and who were surveyed 50 years later (in 2000). Their physical activity level after 50 years was correlated and regressed across a wide number of demographic, behavioral, and personality variables from when they were 50 years younger. Data was analyzed in 2012. In contrast to prior beliefs, self-rated personality profile as a young man had little predictive influence on later-life physical activity. Instead, the single strongest predictor of later-life physical activity was whether he played a varsity sport in high school, and this was also related to fewer self-reported visits to the doctor. Encouraging systematic or frequent physical activity at a young age - whether through school sports or club opportunities - might be the best investment in long-term activeness. This is relevant at a time when funding for many sports programs is being eliminated and play time is being replaced with screen time.

    Cytokinins play an important role in vascular development. But knowledge on the cellular localization of this growth hormone in the stem and other organs of woody plants is lacking. The main focus of this study was to investigate the occurrence and cellular localization of active cytokinins in leaves, roots, and along the stem of Populus × canescens and to find out how the pattern is changed between summer and winter. An ARR5::GUS reporter construct was used to monitor distribution of active cytokinins in different tissues of transgenic poplar lines. Three transgenic lines tested under outdoor conditions showed no influence of ARR5::GUS reporter construct on the growth performance compared with the wild-type, but one line lost the reporter activity. ARR5::GUS activity indicated changes in the tissue- and cell type-specific pattern of cytokinin activity during dormancy compared with the growth phase. ARR5::GUS activity, which was present in the root tips in the growing season, disappeared in winter. In the stem apex ground tissue, ARR5::GUS activity was higher in winter than in summer. Immature leaves from tissue-culture grown plants showed inducible ARR5::GUS activity. Leaf primordia in summer showed ARR5::GUS activity, but not the expanded leaves of outdoor plants or leaf primordia in winter. In stem cross sections, the most prominent ARR5::GUS activity was detected in the cortex region and in the rays of bark in summer and in winter. In the cambial zone the ARR5::GUS activity was more pronounced in the dormant than in growth phase. The pith and the ray cells adjacent to the vessels also displayed ARR5::GUS activity. In silico analyses of the tissue-specific expression patterns of the whole PtRR type-A family of poplar showed that PtRR10, the closest ortholog to the Arabidopsis ARR5 gene, was usually the most highly expressed gene in all tissues. In conclusion, gene expression and tissue-localization indicate high activity of cytokinins not only in summer, but

    The effects of tillage regimen (conventional [CT] and no-tillage [NT]) on the activity density and diversity of carabid beetles (Coleoptera: Carabidae) was studied by pitfall trapping within a rain-fed cropping system in northwestern Idaho, 2000-2002. The cropping rotation consisted of a spring cereal (barley, Hordeum vulgare L., in 2000 and 2001; and wheat, Triticum aestivum L., in 2002), spring dry pea (Pisum sativum L.) 2000-2002, and wheat (T. aestivum), spring in 2000 and 2001, and winter in 2002. A total of 14,480 beetles comprised of 30 species was captured, with five numerically dominant species [Poecilus scitulus L., Poecilus lucublandus Say, Microlestes linearis L., Pterostichus melanarius Ill., and Calosoma cancellatum (Eschscholtz)], accounting for 98% of all captures. All species including the dominants responded idiosyncratically to tillage regimen. Adjusting for trapping biases did not significantly change seasonal activity density of Poecilus spp. or Pt. melanarius to tillage. More beetles were captured in CT than in NT crops because of the dominance of P. scitulus in CT, whereas species richness and biological diversity were generally higher in NT crops. Observed patterns suggest that direct effects of tillage affected some species, whereas indirect effects related to habitat characteristics affected others. CT may provide habitat preferable to xerophilic spring breeders. A relationship was found between beetle species size and tillage regimen in pea and to a lesser extent across all spring crops, with large species (>14 mm) conserved more commonly in NT, small species (tillage systems.
