Adopting both a self-determination theory perspective and a proactive, asset-oriented approach to coping with stressors, we propose a hypothesized model to explain physical education students’ year-long development of course-specific grit-perseverance (Study 1) and mental toughness (Study 2). In both studies, we used a randomized controlled trial research design with longitudinally assessed dependent measures (four waves) to test a hypothesized model in which teacher participation in an autonomy-supportive teaching workshop (experimental condition) would increase students’ T2 perceived autonomy-supportive teaching and T2 perceived autonomy-supportive classmates, both of which would increase T3 need satisfaction, which would then explain longitudinal gains in students’ T4 grit-perseverance (Study 1) and mental toughness (Study 2). In both Study 1 (57 teachers, 3,147 students) and Study 2 (38 teachers, 2,057 students), a multilevel structural equation modeling analysis showed that the hypothesized model fit the data very well. We conclude that the developmental roots of grit-perseverance and mental toughness can emerge proactively out of the asset-oriented experiences of interpersonal support and psychological need satisfaction that are central to self-determination theory.

Identifying Multicomponent Patterns and Correlates of Accelerometry-Assessed Physical Behaviors Among Postmenopausal Women: The Women’s Health Accelerometry Collaboration
Kelly R. Evenson, Annie Green Howard, Fang Wen, Chongzhi Di, and I-Min Lee
Understanding the simultaneous patterning of accelerometer-measured physical activity and sedentary behavior (physical behaviors) can inform targeted interventions. This cross-sectional study described multicomponent patterns and correlates of physical behaviors using accelerometry among diverse postmenopausal women. The Women’s Health Accelerometry Collaboration combined two United States-based cohorts of postmenopausal women with similar accelerometry protocols and measures. Women (n = 22,612) aged 62–97 years enrolled in the Women’s Health Study (n = 16,742) and the Women’s Health Initiative Objective Physical Activity and Cardiovascular Health Study (n = 5,870) wore an ActiGraph GT3X+ accelerometer on their hip for 1 week. Awake-time accelerometry data were summarized using the accelerometer activity index into sedentary behavior, light (low, high), and moderate to vigorous physical activity. Latent class analysis was used to classify physical behavior hour-by-hour. Five unique patterns were identified with higher total volume of physical activity and lower sedentary behavior with each successively higher class number based on percentage of the day in physical activity/sedentary behavior per hour over 7 days. The percentage assignment was 16.3% Class 1, 33.9% Class 2, 20.2% Class 3, 18.0% Class 4, and 11.7% Class 5. The median posterior probabilities ranged from 0.99 to 1.00. Younger age, higher education and general health, normal weight, never smokers, weekly drinking, and faster self-reported walking speed generally had higher-class assignments compared with their counterparts. History of diabetes and cardiovascular disease generally had lower-class assignments compared with those without these conditions. These results can inform targeted interventions based on common patterns of physical behaviors by time of day among postmenopausal women.
Challenges and Future Directions for Promoting Intersectional Quantitative Studies in Physical Activity Research
Mari Sone, Teatske M. Altenburg, and Mai J.M. ChinAPaw
Understanding health inequalities is essential for improving social justice. Intersectionality refers to a theoretical framework for studying the intersection of multiple social categorizations that create unique experiences and related social inequalities. Currently, the majority of the intersectional studies in the physical activity field have a qualitative design; thus, there is a need for quantitative intersectional studies. This commentary aims to explore primary obstacles impeding intersectional quantitative research and provide recommendations for overcoming these obstacles in physical activity research. In the commentary, we discuss that the lack of accessibility of large-scale and diverse data sets, and suboptimal social categorizations and intersectionality-related questions may contribute to the scarcity of intersectional quantitative research in the field. To facilitate intersectional quantitative analyses, we advocate for making large-scale data sets accessible for intersectional secondary analyses, diverse sampling, standardizing questions and categories related to intersectionality, promoting inclusive research designs and methods, and using the appropriate questions and social categorization that reflect the distinct experiences of each subgroup. By addressing these challenges, researchers may gain new insights into health disparities, making physical activity research more inclusive and contributing to more equitable health outcomes.

Background: To meet the World Health Organization goal of reducing physical inactivity by 15% by 2030, a multisectoral system approach is urgently needed to promote physical activity (PA). We report the process of and findings from a codesigned systems mapping project to present determinants of PA in the context of urban New South Wales, Australia. Methods: A participatory conceptual mapping workshop was held in May 2023 with 19 participants working in education, transportation, urban planning, community, health, and sport and recreation. Initial maps were developed and refined using online feedback from the participants. Interviews were conducted with 10 additional policymakers from relevant sectors to further refine the maps. Results: Two systems maps were cocreated, identifying over 100 variables influencing PA and their interconnections. Five settings emerged from the adults’ map—social and community, policy, built environment and transportation, health care, and workplace—and 4 for the young people’s map—family, school, transportation, and community and environment. The maps share similarities, such as regarding potential drivers within the transportation, community, and built environment sectors; however, the young people’s map has a specific focus on the school setting and the adults’ map on workplace and health care settings. Interviews with policymakers provided further unique insights into understanding and intervening in the PA system. Conclusions: This codesigned participatory systems mapping process, supplemented by stakeholder interviews, provided a unique opportunity to bring together stakeholders across sectors to understand the complexity within the PA system and begin to identify leverage points for tackling physical inactivity in New South Wales.
Navigating Virtual Collisions: Insights Into Perception–Action Differences in Children and Young Adults Using a Head-On Avoidance Task
Megan Hammill, Victoria Rapos, and Michael Cinelli
Children tend to make more last-minute locomotor adjustments than adults when avoiding stationary obstacles. The purpose of this study was to compare avoidance behaviors of middle-aged children (10–12 years old) with young adults during a head-on collision course with an approaching virtual pedestrian. Participants were immersed in a virtual environment and completed a perceptual decision-making task in which they had to respond to the future direction of an approaching virtual pedestrian once they disappeared. Following the perceptual task, participants walked along an 8-m pathway toward a goal, while avoiding a collision with a virtual pedestrian who approached along the midline than veered toward the left, right, or continued walking straight. Results revealed that children were able to correctly predict the future directions of the virtual pedestrian similar to adults, albeit at a slower response time (0.55 s vs. 0.33 s). During the action task, children initiated a deviation in their travel path later (i.e., closer to the virtual pedestrian) compared to adults (1.65 s vs. 1.52 s). Children were also more variable in their onset of deviation and time-to-contact. Although children appear to have developed adult-like perceptual abilities and can avoid an approaching virtual pedestrian, children employ riskier avoidance strategies and are highly variable, suggesting middle-aged children are still fine-tuning their perception-action system.
Community-Based Physical Activity Programs for Blood Pressure Management in African Americans: A Scoping Review
Dennis Miezah, Julie A. Wright, and Laura L. Hayman
Background: Hypertension is a significant risk factor for cardiovascular disease, with a higher prevalence among African Americans (AA) than other racial groups. The impact of community-based interventions on managing blood pressure (BP) in AA communities is not fully understood. The purpose of this review was to synthesize literature on community-based physical activity (PA) programs designed to manage BP in AA populations. Methods: We conducted a scoping review by searching 4 databases (PubMed, CINAHL, MEDLINE, and APA PsycInfo) and reference lists of studies. Search terms included community PA, community-based, hypertension, high BP, AA, Black Americans, PA, and exercise. Inclusion criteria were studies (1) conducted in the United States and (2) published in English language from January 2013 to September 2023, with community-based interventions that included PA for BP management among AA aged ≥18 years. Results: Search results yielded 260 studies, of which 11 met the inclusion criteria. BP decreased over time in studies that incorporated PA, faith-based therapeutic lifestyle changes with nutritional education. The duration of the PA interventions varied, with moderate to vigorous PAs implemented for 12 weeks or longer having a greater impact on BP management. Conclusions: Evidence suggests that community-based PA programs can potentially reduce BP among AA. PA programs incorporating faith-based therapeutic lifestyle change with nutritional education appear to reduce BP. Practitioners should consider multicomponent community-based PA initiatives to improve BP outcomes in AA communities.

Mary-Grace Kang, Gabriella Isabel Tablante, Kristofferson Mendoza, Aila Nica Bandong, Roselle Guisihan, Audrey Anne Lim, Frances Rom Lunar, Carlos Dominic Olegario, Esmerita Rotor, and Yves Palad
Background: Primary carers, school teachers, and administrators are key influencers in promoting active lifestyle among children with disabilities (CWD). Guided by the Capability, Opportunity, Motivation, Behavior Model, the Promoting Active Lifestyle among CWD (PALS) Questionnaire aims to determine these influencers’ perceptions, capabilities, opportunities, and motivations in active healthy lifestyle promotion. This study evaluated the content validity and feasibility of the PALS Questionnaire in Filipino and English. Methods: Six experts rated the relevance of the items in the Filipino and English versions of the PALS Questionnaire. Item and scale content validity indices and agreement among raters (modified kappa k*) were computed. The questionnaires were revised and pilot tested among 11 participants comprising primary carers, and special education teachers and administrators using 3 methods of administration: online survey, phone interview, and pen-and-paper survey. Results: Scale-level content validity index indicated excellent content validity (0.96–0.97). Item-level content validity index ranged between 0.67 and 1.00. Interrater agreement on the relevance of all items was excellent (k* = .82–1.00), except for the item on teaching assistants (k* = .56). Most participants found the items easy to understand. The average time needed to complete a questionnaire was 30 minutes. The online version of the questionnaire was identified as the most feasible mode of administration. Conclusion: The PALS Questionnaire is a useful instrument for understanding Filipino primary carers’ and educators’ perceptions on promoting CWD’s active healthy lifestyle. Information from the PALS Questionnaire could inform initiatives toward better CWD health and quality of life.

Effects of Tai Chi Chuan on Older Adults’ Balance: A Systematic Review With Meta-Analysis
Rafael Bertolini, Rafael Vercelino, Luis Fernando Ferreira, and Luis Henrique Telles da Rosa
Background: Tai Chi Chuan (TCC) is considered a mind and body practice of Chinese origin, considered as an intangible cultural heritage of humanity by UNESCO, and recommended by the World Health Organization as a therapeutic approach to prevent falls. Objective: To assess the effects of TCC on older adult’s balance. Methods: A systematic review of randomized clinical trials was conducted by two independent reviewers using the ROB2 tool to assess the risk of bias under the following databases: PubMed, SCOPUS, Web of Science, PEDro, Embase, Cochrane, CINAHL, and LILACS. A meta-analysis of the selected articles for the dynamic and static balance criteria was conducted in a population of older adults (over 65 years) with publications from 2010 to 2024. Results: Eighteen randomized clinical trials fulfilled the criteria. TCC improves dynamic balance in the timed up and go and gait speeds tests, and static balance in the single-leg test and functional reach test when compared with the control group in the meta-analysis. Adverse events were found in only one study, and the training parameters were heterogeneous. Conclusion: TCC improves older adults with both dynamic and static balance. The results of the parameters indicate a direction in which TCC is prescribed for clinical practice with minimal or no risk of adverse effects.
Gaze Behaviors, Estimated Quiet Eye Characteristics, and Decision Making of Nonexpert Assistant Referees Judging Offside Events in Soccer
Carlos Albaladejo-García, Vicente Luis-del Campo, Jesús Morenas, and Francisco J. Moreno
The study analyzed the gaze behavior and decision-making performance of 20 soccer assistant referees while judging offside events. Specifically, gaze behaviors, gaze entropy, and estimated quiet eye (eQE; defined as the last fixation prior to the attacker’s ball pass) characteristics (i.e., location, onset, offset, and duration) were analyzed in relation to decision-making accuracy. Although a significant number of fixations were observed on the offside line, the highest viewing time corresponded to the ball carrier. The gaze behavior indicated a high distribution of fixations, as evidenced by high stationary gaze entropy (>90%). The assistant referees also distinguished offside from onside positions above chance. However, they displayed nonprolonged eQE on the offside line. As a result, no significant relationships were found between the eQE characteristics and decision-making accuracy. The study concludes that the absence of more functional gaze behaviors, specifically with longer eQE focused on the offside line, impaired the decision-making accuracy of nonexpert assistant referees in soccer.
