Background:

The Active Healthy Kids 2016 United Arab Emirates (UAE) Report Card provides a systematic evaluation of how the UAE is performing in supporting and engaging physical activity (PA) in children and adolescents.

Methods:

The Active Healthy Kids Global Alliance framework and standardized set of procedures were used to perform the systematic assessment of PA in UAE youth and children. Indicator grades were based on the proportion of children and youth achieving a defined benchmark: A = 81% to 100%; B = 61% to 80%; C = 41% to 60%; D = 21% to 40%; F = 0% to 20%; INC = incomplete data.

Results:

Overall Physical Activity Level and Active Transportation both received a grade of D-/F-. Sedentary Behavior and Family and Peers both received a C- minus grade and School was graded D. Minus grades indicate PA disparities related to age, gender, nationality, socioeconomic status, and geographic location. Government Strategies and Investments received a B+ grade. Sport Participation, Active Play, and Community and the Built Environment were graded INC due to a lack of nationally representative data for all 7 emirates.

Conclusions:

The majority of UAE children are not achieving the daily recommended level of PA. The UAE leadership has invested significant resources into improving PA through school- and community-based PA interventions; however, inter- and intraemirate population-based strategies remain fragmented.

Around the world, there is a growing movement to improve sport coaching education. In recent years, the International Council for Coaching Excellence (ICCE) has begun to address questions related to the education, training and development of sport coaches through the publication of the International Sport Coaching Framework (ISCF) and the Sport Coaching Bachelor Degree Standards (SCBDS). In the United States, because sport coaches can undertake a wide variety of coaching-related educational opportunities, the United States Olympic Committee has taken steps to address the disparity in training through the publishing of the Quality Coaching Framework (QCF). All of these documents provide valuable information about the best principles for educating and training sport coaches. While principles, standards and theories provide valuable overarching information about how to organize education, specific information about what topics should actually be taught in education programs is still lacking. In this manuscript, utilizing principles of participation versus performance sport and professional knowledge, intra- and interpersonal skills, information about what and when to teach important sport coaching topics is proposed.

The use of cold-water immersion (CWI) for postexercise recovery has become increasingly prevalent in recent years, but there is a dearth of strong scientific evidence to support the optimization of protocols for performance benefits. While the increase in practice and popularity of CWI has led to multiple studies and reviews in the area of water immersion, the research has predominantly focused on performance outcomes associated with postexercise CWI. Studies to date have generally shown positive results with enhanced recovery of performance. However, there are a small number of studies that have shown CWI to have either no effect or a detrimental effect on the recovery of performance. The rationale for such contradictory responses has received little attention but may be related to nuances associated with individuals that may need to be accounted for in optimizing prescription of protocols. To recommend optimal protocols to enhance athletic recovery, research must provide a greater understanding of the physiology underpinning performance change and the factors that may contribute to the varied responses currently observed. This review focuses specifically on why some of the current literature may show variability and disparity in the effectiveness of CWI for recovery of athletic performance by examining the body temperature and cardiovascular responses underpinning CWI and how they are related to performance benefits. This review also examines how individual characteristics (such as physique traits), differences in water-immersion protocol (depth, duration, temperature), and exercise type (endurance vs maximal) interact with these mechanisms.

In judo competition for visual impairment, athletes of different classes compete against each other in the same category; B1 athletes are totally blind, whereas B2 and B3 athletes are partially sighted. To test for potential competition disparities due a single category of athletes, this study aimed to compare competitive and technical–tactical performance in visually impaired judo athletes with different degrees of visual impairment. The authors analyzed 340 judo matches from the 2012 and 2016 Paralympic Games. The scores, penalties, efficiency index, and types of medals were examined, as well as the technical variation and temporal structure. The main finding was that blind judo athletes presented lower scores (p < .05; effect size [ES] = 0.43–0.73), medals (p < .05), and efficiency (p < .05; ES = 0.40–0.73); different patterns of play; and a shorter time to lose than partially sighted athletes (p = .027; ES = 0.10–0.14). However, the penalties were similar between classes (p > .05; ES = 0.07–0.14). The odds ratio of a winning medal was 3.5–8 times less in blind athletes than in partially sighted athletes (p < .01). In conclusion, blind judo athletes presented lower competitive and technical–tactical performance than athletes with some residual functional vision. These findings provide support for the development of new evidence-based criteria for judo classification based on vision impairment.

Background:

At the population level, the prevalence of physical activity has declined considerably in many developed countries in recent decades. There is some evidence that areas exhibiting the lowest activity levels are those which have undergone a particularly strong transition away from employment in physically demanding occupations. We propose that processes of deindustrialization may be causally linked to unexplained geographical disparities in levels of physical activity. While the sociocultural correlates of physical activity have been well studied, and prior conceptual frameworks have been developed to explain more general patterns of activity, none have explicitly attempted to identify the components of industrial change that may impact physical activity.

Methods:

In this work we review the current literature on sociocultural correlates of health behaviors before using a case study centered on the United Kingdom to present a novel framework that links industrial change to declining levels of physical activity.

Results:

We developed a comprehensive model linking sociocultural correlates of physical activity to processes associated with industrial restructuring and discuss implication for policy and practice.

Conclusions:

A better understanding of sociocultural processes may help to ameliorate adverse health consequences of employment decline in communities that have experienced substantial losses of manual employment.

Objective:

To investigate half-marathon runners’ frequency of use of recovery strategies, perceptions regarding the most beneficial recovery strategy, and reasons for using recovery strategies.

Design:

Cross-sectional survey.

Participants:

186 participants of the 13.1 mile BUPA Great North Run 2013.

Methods:

A questionnaire was developed which required participants to indicate how frequently they used 12 different recovery strategies, identify which recovery strategy they believed to be most beneficial, and rank 6 reasons for using recovery strategies in order of importance. Data were analyzed using a Friedman nonparametric ANOVA and additional nonparametric tests.

Results:

All participants used recovery strategies. Stretching was the most commonly used recovery strategy (P < .001), whereas the use of nutritional supplements was the most commonly selected most beneficial recovery strategy. More than 50% of respondents indicated that they never used strategies such as kinesio tape (80%), hydrotherapy (78%), or ice baths (71%). A significant difference was observed between reasons for using recovery strategy (χ2 (5) = 292.29, P < .001). Reducing muscle tightness (rank 4.87) and reducing injury (rank 4.35) were the most frequently chosen most important reasons for using recovery strategies. Minor sex and age differences in the responses were identified.

Conclusion:

Recovery strategy usage appears to be widespread among half-marathon runners; however, disparities exist between the frequency of use and perceived effectiveness of different recovery strategies. Further research in this area is needed to facilitate the development of recovery strategy guidelines which are both evidence-based and practically relevant.

Background:

This study compared moderate-to-vigorous physical activity (MVPA) and sedentary behavior in U.S.–born and foreign-born adolescents and young adults, and differences in behavior change from adolescence to young adulthood by nativity.

Methods:

Data on 2039 U.S.–born and 225 foreign-born participants from Project EAT-III (Eating and Activity in Teens and Young Adults) were used to examine MVPA, television/DVD/video viewing, and computer use. Participants completed surveys at baseline in Minneapolis/St. Paul, MN secondary school classrooms in 1998–1999 (14.9 ± 1.6 y) and follow-up measures online or by mail in 2008–2009 (25.3 ± 1.6 y).

Results:

At both time points, foreign-born participants reported significantly lower levels of MVPA than their U.S.–born counterparts (P < .05). Foreign-born females at baseline and follow-up and foreign-born males at follow-up reported less television/DVD/video viewing compared with U.S.–born participants (P < .01). All participants experienced a significant decline in MVPA from baseline to follow-up (P < .001). Between-group analyses revealed a significantly greater decline in television/DVDs/video viewing for the foreign-born males compared with U.S.–born males from baseline to follow-up (mean change: foreign-born: –4.8 ± 1.32 hrs/wk, U.S.–born: –0.6 ± 0.6 hrs/wk; P < .01).

Conclusions:

Differences in activity patterns between foreign-born and U.S.–born youth into young adulthood may contribute to disparities in chronic disease risk. Nativity, along with the social, environmental, and cultural context, should be considered when designing programs to promote MVPA and prevent obesity.

Purpose: Investigations into the specificity of rugby union training practices in preparation for competitive demands have predominantly focused on physical and physiological demands. The evaluation of the contextual variance in perceptual strain or skill requirements between training and matches in rugby union is unclear, yet holistic understanding may assist to optimize training design. This study evaluated the specificity of physical, physiological, perceptual, and skill demands of training sessions compared with competitive match play in preprofessional, elite club rugby union. Methods: Global positioning system devices, video capture, heart rate, and session ratings of perceived exertion were used to assess movement patterns, skill completions, physiologic, and perceptual responses, respectively. Data were collected across a season (training sessions n = 29; matches n = 14). Participants (n = 32) were grouped in playing positions as: outside backs, centers, halves, loose forwards, lock forwards, and front row forwards. Results: Greater total distance, low-intensity activity, maximal speed, and meters per minute were apparent in matches compared with training in all positions (P < .02; d > 0.90). Similarly, match heart rate and session ratings of perceived exertion responses were higher than those recorded in training (P < .05; d > 0.8). Key skill completions for forwards (ie, scrums, rucks, and lineouts) and backs (ie, kicks) were greater under match conditions than in training (P < .001; d > 1.50). Conclusion: Considerable disparities exist between the perceptual, physiological, and key skill demands of competitive matches versus training sessions in preprofessional rugby union players. Practitioners should consider the specificity of training tasks for preprofessional rugby players to ensure the best preparation for match demands.
