Purpose: This study examined changes in physical education teachers’ psychosocial perspectives after participating in a yearlong professional development about Comprehensive School Physical Activity Programming. Method: Twenty-three intervention teachers attended a workshop in Year 1 and received one academic year of technical assistance and mentorship, and 30 control teachers only attended a workshop in Year 2. Both groups completed pre- and post-self-reported measures on teacher efficacy, work engagement, and affective commitment. Results: At posttest, intervention teachers reported significantly higher levels of affective commitment, and a significant positive relationship was revealed between affective commitment and the degree to which before-school physical activity was implemented. More experienced teachers (>20 years) reported significantly higher levels of the work engagement subscale of vigor at posttest. Discussion/Conclusion: Participating in a Comprehensive School Physical Activity Program professional development may positively influence teachers’ job commitment levels and invigorate more experienced teachers, which may relate to Comprehensive School Physical Activity Program implementation.

There appears to be general agreement that interaction with significant challenge should be a central feature of the development pathways for future high performers. There is, however, far less clarity about how such programs should be designed and delivered against core psychological principles. Accordingly, the purpose of this paper is to offer guidelines for talent development practitioners seeking to offer athletes the opportunity to maximize their growth and development. The authors propose that genuinely developmental experiences will likely offer a level of emotional disturbance and, as a result, more fully engage performers, prompting self and other facilitated reflection, and motivate future action. Furthermore, there is a necessity for these experiences and their follow-up, to be managed in a coherent manner and integrated with existing skills, experience, and future performance aims. In highlighting these issues, the authors offer recommendations for talent development coaches, managers, psychologists, and parents of athletes.

Purpose: Guided by the declarative−procedural knowledge framework, the study attempts to identify middle school students’ declarative (knowing what) and procedural (knowing how) fitness knowledge and the relationship between the two. Methods: A sample of students (n = 291, age 11–14 years) from 24 middle schools took a grade-relevant standardized knowledge test on declarative fitness knowledge and received a semistructured interview designed to clarify their declarative and procedural knowledge. Results: Most students were lacking in procedural knowledge to conduct fitness-enhancing physical activities. A few students who had mastered declarative fitness knowledge demonstrated a high level of procedural knowledge consistent with personal fitness goals. Discussion: The findings suggest that incapability to engage in fitness-enhancing physical activities could be a result of lacking procedural fitness knowledge. Future school-based interventions may prioritize procedural knowledge learning for actual physical activity participation.

In September 2019, 19,000 amateur runners participated in the Canada Army Run, a road race hosted by the Canadian Forces (CF). This ethnographic study explores the event as a site of socialization, demonstrating that the Army Run: (a) focuses on promoting the CF rather than maximizing race results, (b) promotes the CF by exceptionalizing its members, and (c) is a celebratory site of promilitary socialization and recruitment that precludes critical engagement with the CF. These findings indicate that military promotional strategies have evolved since the immediate post 9/11 era; whereas previous initiatives used sport to tie local military agendas into larger neoliberal military imperatives, the 2019 Army Run demonstrates a new tactic, depoliticizing the CF and reifying an idealized, decontextualized Canadian military.

This study aimed to investigate the association between compliance with the guidelines of moderate to vigorous physical activity (MVPA) accumulated in bouts of ≥10 min or nonbouts with body composition and physical function in older adults. The authors evaluated 230 noninstitutionalized older adults. Body composition was estimated using bioimpedance, and physical function was assessed using four physical tests. Physical activities were monitored for 7 days using an accelerometer. Older adults who were physically active according to MVPA in bouts of ≥10 min were less likely to have low appendicular skeletal muscle mass (odds ratio [OR] = 0.12), excess body fat (OR = 0.30), and abdominal obesity (OR = 0.34) and more likely to have a higher physical function (OR = 5.78). No significant association was observed with MVPA nonbout. Our findings indicate that older adults who accumulate MVPA in bouts of ≥10 min have better parameters for body composition and physical function.

The balance of angiogenic factors, including vascular endothelial growth factor (VEGF), and angiostatic factors, like thrombospondin-1 (TSP-1) and endostatin, controls striated muscle angiogenic responses to exercise training. The effect of age on circulating levels of these factors following a bout of exercise is unclear. The authors hypothesized that older adults would have lower circulating VEGF but higher TSP-1 and endostatin after exercise compared with young adults. Ten young and nine older participants cycled for 45 min at 60% estimated HRmax. Serum [VEGF], [TSP-1], and [endostatin] obtained before (PREX), immediately after (POSTX0), and 3 hr after (POSTX3) exercise were analyzed. [VEGF] increased in older adults only from PREX to POSTX0 (p < .05). [TSP-1] increased in both age groups (p < .05). There was no effect of age or exercise on [endostatin]. In conclusion, immediately after exercise, both groups had a similar increase in [TSP-1], but [VEGF] increased in older adults only.

Objective: To analyze the feasibility, safety, and acceptability of immersive virtual tasks. Methods: The authors recruited 11 young adults and 10 older adults. The participants performed three virtual reaching tasks while walking on a virtual path. The descriptive analysis and comparison between participants were performed using the Mann–Whitney U test and chi-square test for nonparametric and nominal variables, respectively. The authors also used analysis of variance for a between-groups comparison for normal variables. Results: Twenty percent of older adults and 81.8% of young adults completed all three tasks (chi-square test; p = .005). Both groups reported minor symptoms, with no significant differences. The older adults were more motivated to practice the tasks (Mann–Whitney U test; p = .015) and would be more likely to suggest them to others (chi-square test; p = .034). Conclusion: All three tasks were feasible for young adults. All participants, except for one, had cybersickness. The symptoms were mostly mild and subsided once the interaction was complete.
