Background:

Understanding the factors that contribute to physical activity (PA) in Mexican-origin adolescents is essential to the design of effective efforts to enhance PA participation in this population.

Methods:

Multivariable logistic regression was used to identify sociodemographic and behavioral correlates of self-reported PA in school and community settings in 1154 Mexican-origin adolescents aged 12–17 years in Houston, TX.

Results:

The majority of adolescents were born in the US (74%), approximately half (51%) were overweight or obese, and nearly three-quarters (73%) watched more than 2 hours of weekday television. Similarities and differences by setting and gender were observed in the relationships between sociodemographic and behavioral characteristics and PA. In boys, parental education and attending physical education (PE) were positively associated with PA across multiple PA outcomes. Adolescent linguistic acculturation was inversely associated with participation in community sports, whereas parental linguistic acculturation was positively associated with PA at school. In girls, PA in school and community settings was inversely associated with TV viewing and positively associated with PE participation.

Conclusions:

These findings highlight similarities and differences in correlates of PA among boys and girls, and point toward potential sources of opportunities as well as disparities for PA behaviors in Mexican-origin adolescents.

Background:

This comparative case study investigates 2 successful community trail initiatives, using the Active Living By Design (ALBD) Community Action Model as an analytical framework. The model includes 5 strategies: preparation, promotion, programs, policy, and physical projects.

Methods:

Key stakeholders at 2 sites participated in in-depth interviews (N = 14). Data were analyzed for content using Atlas Ti and grouped according to the 5 strategies.

Results:

Preparation: Securing trail resources was challenging, but shared responsibilities facilitated trail development. Promotions: The initiatives demonstrated minimal physical activity encouragement strategies. Programs: Community stakeholders did not coordinate programmatic opportunities for routine physical activity. Policy: Trails’ inclusion in regional greenway master plans contributed to trail funding and development. Policies that were formally institutionalized and enforced led to more consistent trail construction and safer conditions for users. Physical Projects: Consistent standards for wayfinding signage and design safety features enhanced trail usability and safety.

Conclusions:

Communities with different levels of government support contributed unique lessons to inform best practices of trail initiatives. This study revealed a disparity between trail development and use-encouragement strategies, which may limit trails’ impact on physical activity. The ALBD Community Action Model provided a viable framework to structure cross-disciplinary community trail initiatives.

Background:

Curriculum interventions aimed at increasing physical activity in schools may prove useful in contexts where changes in policy/environment are not feasible. Design/evaluation of interventions targeting minority groups is important in light of well-publicized health disparities. Religious minorities represent a special subset that may positively respond to interventions tailored to their unique beliefs, which to date have been relatively underreported.

Methods:

Muslim American youth (n = 45) attending a parochial middle school participated in a religiously- and culturally-tailored 8-wk, interdisciplinary pedometer intervention. School-time ambulatory activity was quantified using a delayed multiple-baseline across subjects ABA design. Visual analysis of graphic data as well as repeated-measures ANOVA and ANCOVA and post hoc contrasts were used to analyze step counts including the moderating effects of day type (PE, no-PE), gender, BMI classification, grade, and time.

Results:

The intervention elicited modest increases in males’ steps only with effect decay beginning midintervention. BMI classification and grade were not associated with changes in steps.

Conclusions:

Full curricular integration by affected classroom teachers, staff modeling of PA behavior, and alternative curriculum for girls’ PE classes may further potentiate the intervention.

Background:

Racial health disparities are more pronounced among older adults. Few studies have examined how racism influences health behaviors. This study’s purpose was to examine how opportunities for physical activity (PA) and community racism are associated with older racial minorities’ reported engagement in PA. We also investigated how PA levels influenced health.

Methods:

We analyzed survey data obtained from a health assessment conducted in 3360 households in Texas, USA, which included items pertaining to PA, community characteristics, and health.

Results:

Our sample contained 195 women and 85 men (mean age 70.16), most of whom were African American. We found no direct relationship between opportunities and PA. Results suggested that perceived community racism moderated this association. When community racism was low, respondents found ways to be active whether they perceived opportunities or not. When community racism was high, perceived lack of opportunities significantly impeded PA engagement. We found the expected association between PA and health.

Conclusions:

Results suggested that negative effects of community racism were counteracted through increased opportunities for PA.

This case study illustrates the complexity of decision making in public organizations, specifically highlighting the public health concern of drowning disparities in the United States. Using escalation of commitment theory, students must consider various factors in evaluating the overextended commitments of a local government in a complicated sociopolitical environment and with vital public needs that must be addressed through a local parks and recreation department. Facing a reduction in allocated resources, the department director, Claire Meeks, is tasked with determining which programs will receive higher priority despite the varied feedback from the management staff. To ensure students are provided a realistic scenario, this case offers a combination of fictional and real-life events from Splash Mid-South, an innovative swimming program in Memphis, Tennessee. Students must critically evaluate not only the merits of the swimming program, but the other sport, recreation, and parks programs that also merit an equitable share of the limited resources. Therefore, students are placed in a decision-making role that is common to managers of both public and private organizations. This case study is appropriate for both undergraduate and graduate sport management courses, with specific application to strategic management, organizational behavior, and recreation or leisure topics.

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:

Few studies have compared physical activity (PA) and sedentary activity (SA) by grade and ethnicity, specifically including elementary school students. A cross-sectional probability-based design was used to provide data by ethnicity (African American, Hispanic, and White/Other), gender, and grade (4th, 8th, and 11th) from 2000 to 2002.

Methods:

Two validated questionnaires (elementary and secondary) assessed self-reported PA and SA. Point-prevalence estimates and 95% confidence intervals were computed.

Results:

Over 70% of students reported vigorous PA on ≥3 days/week, but <50% participated in daily physical education. A significant percentage (30% to 50%) of students reported ≥3 hours per day in SA. Fourth-grade boys and girls reported equal PA; however, 8th and 11th grade girls reported lowered vigorous PA. African American 8th- and 11th-grade boys reported the highest PA, but African American children also reported the highest prevalence of SA.

Conclusions:

Findings from this study highlight the disparities in physical and sedentary activities by gender, grade, and race/ethnicity, and the need to address these differences with programs and policy. In general, grade level and gender differences were more striking and consistent than racial/ethnic differences.

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:

Neighborhood environment and resources affect physical activity. This study examined the relationships between San Francisco residents’ perceived barriers to physical activity and policy-maker perspectives of conditions in neighborhoods that are under-served for physical activity.

Methods:

Nine focus groups comprised of primarily African American, Chinese American, and Latino populations were constructed from 6 low-income neighborhoods to respond to questions based on the social-ecological model about neighborhood recreational opportunities and to offer policy and intervention strategies to increase physical activity. A tenth focus group was conducted with staff members from 7 city departments to respond to neighborhood focus groups outcomes. The transcribed videotaped discussions were analyzed using qualitative content analysis.

Results:

Both residents and policy-makers highlighted neighborhood disparities that reduce physical activity including unsafe and unhealthy environments and difficulty accessing available resources. Residents reported fewer available free or low-cost resources than those identified by policy-makers.

Conclusions:

Findings suggest that policy-makers would benefit from consideration of neighborhood-level affects of policies on physical activity and local residents’ recommendations for policies affecting physical activity. Concordance between residents’ perceptions and policy-maker perceptions of neighborhood conditions for physical activity was greater than reported in previous literature.

Background: Eliminating racial/ethnic disparities in physical activity remains a challenge in the United States. South Asian immigrants in the United States have particularly low physical activity levels, and evidence suggests that social context may be important. This study examined associations between personal social networks and moderate to vigorous leisure-time physical activity (MVPA) among South Asians in the United States. Methods: We used cross-sectional data (2014–2017) from 689 South Asians (aged 43–85 y) who participated in the Mediators of Atherosclerosis in South Asians Living in America study. Self-reported physical activity and egocentric network data were collected from participants about their network members. Regression models were used to determine associations between social network characteristics and participants’ MVPA. Results: Participants were on average 59 years old (SD = 9) and reported 1335 metabolic equivalent minutes per week of MVPA (interquartile range = 735, 2212). Having network members who exercised or who were exercise partners associated with increased MVPA in men (β coefficient = 241 MET min/wk [95% confidence interval, 63 to 419] and β = 520 MET min/wk [95% confidence interval, 322 to 718], respectively). For women, the association was only significant if the exercise partner was a spouse. Conclusion: Physical activity interventions utilizing network members as exercise partners may have potential in South Asians but must consider gender differences.
