Background:

Recent research demonstrates the importance of targeting the built environment to support individual physical activity, particularly for people experiencing health disparities. Master plans to promote biking and/or pedestrians (BPMPs) are a potential method for environmental change. This descriptive study aims to provide a snapshot of plan attributes and better understand demographic, social and transportation characteristics of communities with BPMPs.

Methods:

We collected a census sample of BPMPs from 4 states. Population and commuting data were obtained from national statistics.

Results:

294 master plans were included, with most plans representing municipalities. 62% of plans targeted biking only, one-fifth targeted biking and walking, and 15% targeted walking only. The sampled locations have a similar demographic profile as the overall U.S. for median age and household income, people of color, high school education, and income inequality. The degree of racial diversity of sampled communities is slightly less than the U.S. average and the percentage of people who walk to work were slightly higher.

Conclusions:

Given that communities with master plans have a similar profile as the overall U.S., BPMPs could feasibly be spread to communities throughout the country. Further research is planned to describe BPMPs in detail toward informing future plan development.

This study is an examintion of the effects of race and income on leisure-time physical activity among women (n = 116). Perceived benefits of and barriers to participating in leisure-time physical activity were also compared. A regression model utilizing social cognitive variables was used to explore factors which may predict physical activity participation. No significant differences emerged between the groups regarding the amount of physical activity they reported either by race or socioeconomic status. Time expenditure emerged significantly different by race (p < .001) and income (p < .000); middle-income women reported time as a barrier more than lower-income women and Whites were likelier to report time as a barrier more than Blacks. Middle-income women perceived greater (p < .01) physical performance benefits from exercise than lower-income women. Social interaction, time expenditure, and body mass index were the strongest predictors of physical activity. The data and findings could be useful for increaseing our understanding of economic and racial disparities in physical activity participation and garnish information for use in constructing interven programs.

The aim of the present study was to locate the fastest 10-m split time (Splitbest) over a 40-m sprint in relation to age and maximal sprint speed in highly trained young soccer players. Analyses were performed on 967 independent player sprints collected in 223 highly trained young football players (Under 12 to Under 18). The maximal sprint speed was defined as the average running speed during Splitbest. The distribution of the distance associated with Splitbest was affected by age (X 2 3 = 158.7, P < .001), with the older the players, the greater the proportion of 30-to-40-m Splitbest. There was, however, no between-group difference when data were adjusted for maximal sprint speed. Maximal sprint speed is the main determinant of the distance associated with Splitbest. Given the important disparity in Splitbest location within each age group, three (U12-U13) to two (U14-U18) 10-m intervals are still required to guarantee an accurate evaluation of maximal sprint speed in young players when using timing gates.

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.

Background:

Youth summer camp programs have the potential to provide opportunities for physical activity, but little to no research has been conducted to determine activity levels of campers. This study aimed to examine physical activity occurring in day and resident summer camps and how activity levels differed in these camps based upon demographic characteristics.

Methods:

Pedometer data were collected during hours of camp operation from 150 day campers and 114 resident campers between the ages of 8 and 12 years old. Independent t tests were used to compare physical activity by sex, race, and Body Mass Index.

Results:

Campers at day camps averaged 11,916 steps per camp day, while resident campers averaged 19,699 steps per camp day. Day campers averaged 1586 steps per hour over 7.5 hour days and resident campers averaged 1515 steps per hour over 13 hour days. Male sex, Caucasian race, and normal Body Mass Index were significant correlates of more physical activity.

Conclusions:

Youth summer camps demonstrate the potential to provide ample opportunities for physical activity during the summer months. Traditional demographic disparities persisted in camps, but the structure of camp programs should allow for changes to increase physical activity for all participants.

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.

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.
