Prioritizing school intramural and interscholastic programs based on observed physical activity

Designing an adolescent physical activity and nutrition intervention before and after COVID-19: A formative research study

BACKGROUND

With rates of childhood obesity continually increasing, effective physical activity (PA) and nutrition interventions are needed. Formative research is used to tailor interventions to different cultural and geographic contexts and can also be vital in adapting intervention strategies in the face of significant disruptive circumstances (like COVID-19).

OBJECTIVE

We conducted formative research via in-person and online focus groups among middle schoolers and parents to better understand barriers and facilitators to PA and fruit and vegetable (FV) consumption and inform the design of a large intervention for a low-income, urban setting in the U.S. Midwest.

METHODS

We conducted two phases of qualitative focus groups with parents (n=20) and 6-9 grade middle schoolers (n=22). Phase 1 was conducted prior to the COVID-19 pandemic in late 2019, and phase 2 was conducted during the COVID-19 pandemic in the summer of 2020. Focus groups were transcribed and thematically coded using Dedoose software.

RESULTS

Main facilitators to PA prior to the pandemic included the opportunity to have fun, peer influence, competition (for some), and incentives, while main barriers to PA were time constraints and social discomfort. Main facilitators to eating FV included parental influence, preparation technique, and convenience, while barriers included dislike of vegetables, time constraints, and preparation or freshness. During the pandemic, facilitators to PA remained the same, while additional barriers to PA such as lack of motivation and limited time spent outside of the home were reported during the pandemic. For FV consumption, both facilitators and barriers remained the same for both time periods. Additionally, for some participants, the pandemic offered an opportunity to offer more FV to middle schoolers throughout the day.

CONCLUSIONS

Some themes identified were common to those reported in previous studies, such as peer influence on PA and parental influence on FV consumption. Novel themes, such as lack of motivation to be active and limited time outside the home, helped improve intervention adaptation, specifically during the COVID-19 pandemic. The continuity of formative research after a major, unexpected change in intervention context can be essential in targeting areas of an intervention that can be retained and those that need to be adjusted.

CLINICALTRIAL

2021 Charles H. McCloy Lecture: "You're Not in Kansas Anymore" by Charles H. McCloy

In this article I envision how Charles H. McCloy might assess the current state of kinesiology in relation to how it evolved from its parent profession of physical education into a field comprised of the scientific enterprise of kinesiology, as well as the related professions and professional preparation programs. I use my interpretation of his scholarship years ago to imagine how he would respond to important developments and advances in the scientific basis of human movement. Overall, despite many advances in the profession, I suspect that he, like I, would opine that the field is at a tipping point. I use his voice to illustrate five key themes that the field must address if it seeks to impact professional practice and the health status of all citizens.

Objective Assessment of Physical Activity and Associated Contexts During High School Sport Practices

Background: Organized sports provide children and adolescents with opportunities to achieve recommended amounts of moderate to vigorous physical activity (MVPA), and schools are a primary setting for sports programs. The main aims of this study were to examine participant physical activity (PA) levels during the most popular high school sports in the United States and to assess the influences of practice contextual factors on PA levels. Methods: Participant PA and its contexts were assessed during practices for the 10 most popular girls' and boys' high school sports in the United States. Data were obtained during 598 practice sessions in 12 schools in North Carolina using a validated direct observation instrument (System for Observing Fitness Instruction Time (SOFIT). A regression model was applied to understand the association between sport context and athletes' PA. Results: Overall, athletes were observed engaging in MVPA 60% of practice time. MVPA varied among sports and levels were highly influenced by practice contexts. Among girls' sports, cross country and soccer practices provided the highest proportion of MVPA and MVPA percent during boys' practice sessions was highest during cross country and track and field. Practice contexts were associated with MVPA accrual with time allocated for gameplay and fitness activities associated with the highest levels of PA. Conclusions: The results contribute to an understanding of which sports and how their practices are conducted facilitate increased PA. Findings indicate athletes accrue substantial amounts of PA during high school practices, but that it varies from sport to sport. As well, the context that characterizes sport practices is a significant determinant in how much PA occurs. Most sports that emphasized game simulation, fitness, and skill development drills had higher levels of MVPA. Given the length and frequency of practices and how the content is delivered, we can accurately predict how much PA athletes are likely to achieve during a given sport season. The findings from this study demonstrate that sport can make a useful, if not sufficient role in helping high school athletes reach recommended PA levels. PA engagement can be optimized by attending to the management of contexts surrounding the sports.

A quasi-experimental examination of how changes in school-level intramurals are associated with physical activity among a sample of Canadian secondary school students from the COMPASS study

Introduction

Intramurals in schools may encourage physical activity among youth. Schools are continuously making changes to these intramurals, yet it is not well understood how these changes impact youth physical activity. The main objective of this research was to examine if changes in the number of intramurals were associated with youth physical activity over time with a secondary objective to explore the association between sport participation and physical activity among youth over time.

Methods

This study used three years of linked longitudinal school- and student-level data from Ontario schools in year 5 (Y5: 2016–2017), year 6 (Y6: 2017–2018) and year 7 (Y7: 2018–2019) of the COMPASS study. Data on intramurals from 55 schools were collected from the School Programs and Policies questionnaire to determine intramural changes that were made from Y5 to Y6. Using the COMPASS Student Questionnaire, baseline demographics were collected and data on physical activity and sport participation were measured at Y5, Y6 and Y7 on 4417 students. Hierarchical linear mixed regression models were used to estimate how changes in intramurals were associated with youth physical activity over time.

Results

Changes in school-specific intramurals were not significantly associated with physical activity over time. Intramural, varsity and community sport participation were all positively and significantly associated with youth physical activity among female and males.

Conclusions

Intramural, varsity and community sport participation are important opportunities for youth physical activity. Schools should offer a variety of intramural and varsity sports to encourage physical activity. Although adding intramurals may not be effective at increasing youth physical activity, they may be effective when used in combination with other strategies to increase physical activity.

•

The use of an indicator variable in multi-level modeling is a novel method to evaluate a natural experiment.

•

Intramural, varsity and community sport participation were positively associated with youth physical activity.

•

Intramural changes were not associated with youth physical activity over time.

•

Intramurals may be a useful part of a more comprehensive approach to increasing youth physical activity.

A School-Level Examination of the Association between Programs and Policies and Physical Activity Outcomes among Females from the COMPASS Study

(1) The majority of Canadian youth are not meeting physical activity guidelines, and more female than male youth are falling short of these recommendations. School programs and policies are a viable strategy to improve youth physical activity. However, they may differentially affect female and male activity. This study aimed to examine school-level differences in physical activity outcomes among male and female students and to explore how school programs and policies associate with school-level physical activity outcomes among females. (2) This study used data from 136 schools participating in year 7 (Y7 2018–2019) of the COMPASS study. Data on school programs and policies and on student physical activity were collected. School-level means and percentages for outcomes were calculated and compared between males and females and the impact of physical activity programs and policies on female physical activity outcomes were examined. (3) More males met the guidelines, achieved more strength training days and physical activity minutes compared to females. The number of female varsity sports, community partnerships and fitness ambassadors were all positively and significantly associated with female physical activity. (4) Supportive physical activity environments fostered by offering varsity sports, establishing community partnerships and positive role models may promote physical activity among female youth.

Examining If Changes in the Type of School-Based Intramural Programs Affect Youth Physical Activity over Time: A Natural Experiment Evaluation

(1) School-based physical activity programs such as intramurals provide youth with inclusive opportunities to be physically active, yet we know little about how types of intramurals (e.g., team and individual sports) may contribute to youth MVPA. This research aims to evaluate how real-world changes in types of intramurals available in schools impact youth physical activity over time. (2) This study used three years of longitudinal school- and student-level data from Ontario schools participating in year 5 (2016-2017), year 6 (2017-2018) and year 7 (2018-2019) of the COMPASS study. Data on types of intramural programs from 55 schools were obtained, baseline demographic characteristics were measured and data on physical activity and sport participation were collected on a sample of 4417 students. Hierarchical linear mixed regression models were used to estimate how changes in the type of intramurals associate with youth MVPA over time. (3) Regardless of participation, adding individual and team intramurals was significantly and positively associated with female MVPA in Y6. (4) The indirect, but positive relationship between adding individual and team intramurals and female MVPA may be explained by other characteristics of the school environment that are conducive to female MVPA.

A cross-sectional examination of the association between co-ed and gender-specific school intramural programs and intramural participation among a sample of Canadian secondary school students

Intramurals are an important part of the physical activity offerings in secondary schools; however, it is not well understood how co-ed and gender-specific intramural programs impact intramural participation among male and female students. Therefore, the objective of this research was to examine if the number of co-ed, male-only, and female-only intramurals offered at a school was associated with student participation in intramurals. A large sample of Canadian secondary school students (N = 59,370) completed the COMPASS survey in 2017-2018. School staff reported the number of co-ed, male-only, and female-only intramurals offered at each school. Students reported whether they participated in school intramurals. Hierarchical models were used to assess associations. Intramural participation was marginally higher among male students (36%) than female students (32%; p < 0.0001). Female students attending schools that offered female-only intramurals were 17% (OR 1.17 [95% CI: 1.05-1.30]) more likely to participate. The number of co-ed and male-only intramurals offered were not significantly associated with student participation. We found a positive association between offering female-only intramurals and female intramural participation, highlighting the importance of these programs for female students. Offering female-only intramurals may be a way for schools to improve participation and physical activity levels of female students. More research is needed on the impact of specific sports or activities on male and female student participation.

Socio-ecological predictors of non-organized physical activity participation and decline between childhood and adolescence

Physical activity (PA) tends to decline during late childhood and adolescence. In Australia, this decline has been shown to particularly occur non-organized PA (e.g., active play, informal sport). This study aimed to explore predictors of non-organized PA at 13y; and decline between 11y and 13y. Data were sourced from the Longitudinal Study of Australian Children. Non-organized PA was measured using time-use diaries. Analyses included Cragg hurdle and binary logistic regressions. The likelihood of non-organized PA at 13y was predicted by PA enjoyment (OR = 1.36, p = 0.007), number of siblings (OR = 1.11, p < 0.001), sex (females) (OR = 0.66, p < 0.001) and home computer use at 11y (OR = 0.98, p = 0.002) (n = 3,193). Females also engaged in less non-organized PA at 13y (β = -77.77, p = 0.048) (n = 3,193). Significant predictors of decline in non-organized PA were socioeconomic position (OR = 0.92, p = 0.047) and sugary drink consumption at 11y (OR = 1.06, p = 0.033) (n = 3,222). Strategies to promote non-organized PA may include targeting females and those of lower socioeconomic position, and focusing on types of PA that may replace the perceived benefits of computer use.

The NBA and Youth Basketball: Recommendations for Promoting a Healthy and Positive Experience

Participation in sports offers both short-term and long-term physical and psychosocial benefits for children and adolescents. However, an overemphasis on competitive success in youth sports may limit the benefits of participation, and could increase the risk of injury, burnout, and disengagement from physical activity. The National Basketball Association and USA Basketball recently assembled a group of leading experts to share their applied research and practices to address these issues. This review includes the group's analysis of the existing body of research regarding youth sports participation and the related health, performance, and psychosocial outcomes. Based upon this, age-specific recommendations for basketball participation are provided that aim to promote a healthy and positive experience for youth basketball players.

Physical Activity and Health-Related Fitness of Adolescents within the Juvenile Justice System

Background

The purpose of this study was to examine the physical activity patterns and health-related fitness levels of adolescents within the Juvenile Justice System.

Methods

Participants included 68 adolescents (Mean age = 17.1 ± 1.0 years) in two secure Juvenile Justice correctional facilities in the Western USA. Moderate-to-vigorous physical activity (MVPA) was monitored for one week using the ActiGraph GT9X accelerometer. Health-related fitness was measured using the FITNESSGRAM test battery.

Results

Adolescents averaged 43.3±21.6 minutes of MVPA per weekday compared to 42.7±27.5 per weekend day. During school hours, adolescents accumulated 17.1±9.0 minutes of MVPA compared to 5.9±3.4 minutes before school and 21.0±13.6 minutes after school. Adolescents averaged 18.9±11.0 push-ups, 44.5±26.4 curl-ups, 34.7±24.8 PACER laps, and 22.1%±10.0% body fat.

Conclusions

Adolescents within the Juvenile Justice System are falling short of the recommended 60 minutes of MVPA per day and 30 minutes of MVPA during school and also need to improve their health-related fitness, especially cardiorespiratory endurance.

Shared use agreements and leisure time physical activity in North Carolina public schools

Although increasing community access to public schools through shared use agreements (SUAs) has been a recommended strategy for promoting physical activity (PA) among national, state and local organizations, empirical evidence examining the efficacy of SUAs is limited. This study examined the degree of usage and production of PA among schools with shared use, and how variation in PA output is related to characteristics of the school, type of activity, facility type, and when activity occurs. Data were collected in 20 schools across North Carolina using System for Observing Play and Recreation in Communities (SOPARC) and Structured Physical Activity Surveys (SPAS) to assess PA in school athletic facilities during out of school time. Findings indicated that although schools had a policy of shared or open use, most facilities were empty during non-school hours. Hierarchal linear regression models also showed that formal programming was positively associated with both use and PA levels. Given the abundance of empty facilities, community groups in need of space to facilitate structured PA programs should pursue avenues of sharing facilities with public schools. Furthermore, to increase the efficacy of shared use, structured physical activity programs may be needed. Future studies are encouraged to further explore the effects of the specific types of shared use programs on PA production as well other aspects of the built environment surrounding schools.

Context Matters: Systematic Observation of Place-Based Physical Activity

Physical activity is place-based, and being able to assess the number of people and their characteristics in specific locations is important both for public health surveillance and for practitioners in their design of physical activity spaces and programs. Although physical activity measurement has improved recently, many investigators avoid or are at a loss regarding the assessment of physical activity in explicit locations, especially in open environments where many people come and go in a seemingly indiscriminate fashion. Direct, systematic observation exceeds other methods in simultaneously assessing physical activity and the contexts in which it occurs. This commentary summarizes the development and use of 2 validated observation tools: the System for Observing Play and Leisure in Youth (SOPLAY) and System for Observing Play and Active Recreation in Communities (SOPARC). Their use is well supported by both behavior-analytic principles and social-ecological theory, and their methods have utility for both researchers and practitioners.

Top 10 research questions related to assessing physical activity and its contexts using systematic observation

Numerous methods are available to assess physical activity (PA) but systematic observation (SO) excels in being able to provide contextually rich data on the setting in which the activity occurs. As SO is particularly useful for determining how activity is influenced by the immediate physical and social environments, its use is becoming more popular. Observation tools have the advantages of flexibility, high internal validity, low inference, and low participant burden, while their disadvantages include the need for careful observer training and recalibration, inaccessibility to certain environments, and potential participant reactivity. There is a need for both scientists and practitioners to have additional information on observation techniques and systems relative to making environmental and policy decisions about PA, and in this article, we describe concepts and identify questions related to using SO in researching PA behavior. We present 10 general questions in 3 sections, including those related to: (a) ensuring data accuracy through the selection of the most appropriate methodological protocols; (b) investigating PA in school settings, including physical education, recess, and other programs; and (c) investigating PA in community settings (e.g., parks, recreation centers, youth and adult sport programs) and homes.

Are the correlates of sport participation similar to those of screen time?

Objective

To explore longitudinal and cross-sectional correlates of sport participation and screen time in a nationally representative sample of Australian children.

Methods

The sample included 3956 child participants taken from the Longitudinal Study of Australian Children. Data were collected in 2004 (age range = 4–5 years) and 2012 (age range = 12–13 years) and included parental estimates of sport participation and total screen time (electronic gaming and television viewing) in addition to demographic, socioeconomic and environmental factors.

Results

Sport participation and total screen time were inversely correlated (r = − .10). Child demographics (sex, pubertal status, general health, and body mass index [BMI]), socioeconomic (neighborhood socioeconomic position, household income, parental education, and parental BMI) and environmental (neighborhood belonging, neighborhood safety, and neighborhood facilities) factors were related to both outcomes — in most cases a positive [negative] correlation with sport participation yielded a corresponding negative [positive] correlation with total screen time.

Conclusion

Our findings show that demographic, socioeconomic and environmental factors measured at age 4 predict sport participation and screen time at age 12, and that the correlates of childhood sport participation and childhood sedentary behavior may be more similar than previously estimated.
