Background: Moderate-to-vigorous physical activity (MVPA) offers many health benefits for preschoolers (2.5–5 y). In childcare, MVPA is predominantly accumulated outdoors, with higher rates purported among children within the first few minutes outside. The Supporting Physical Activity in the Childcare Environment intervention included shorter, more frequent outdoor play sessions; this study sought to explore children’s activity levels during various outdoor play schedules. Methods: During the final week of the Supporting Physical Activity in the Childcare Environment intervention, preschoolers wore an Actical™ accelerometer for 5 days during childcare and staff logged outdoor times. Separate linear mixed effects models were run to explore the effect of the intervention on preschoolers’ physical activity (total and MVPA) and sedentary time during outdoor play. Sex was entered as an interaction effect. Results: Preschoolers (n = 292) were significantly more active in the first 10 minutes outdoors compared with remaining time (P < .0083). For total outdoor time, children in the experimental group engaged in significantly less sedentary time than those in the control group (P < .017), and experimental group boys and girls engaged in higher MVPA than boys and girls in the control group (P < .017). Conclusions: Findings support scheduling more frequent outdoor play sessions in childcare to increase physical activity participation among young children.

Strength and conditioning (S&C) has become a chief part of athletes’ physiological preparation. Despite S&C’s growing presence across sports, women coaches have been generally marginalized and underrepresented. This study explores female S&C coaches’ experiences and coping mechanisms in a male-dominated industry. Semi-structured interviews with 15 female S&C coaches were conducted. The main themes identified from interview data are organizational politics, impression management, and humor. The findings suggest that women S&C coaches are often in subservient positions and have to adopt some traditional, male-generated subcultural practices to fit in. They carefully manage their coaching front stage to generate an impression that is expected and accepted in the given milieu. In their efforts to fit in, women often find themselves in a multiplicity of power matrices that involve a continuous negotiation of gender identity, internal politics, and sexist banter.

Background: Neighborhood parks are important locations to encourage and stimulate physical activity (PA) among the urban population. This study aims to evaluate the impact of an informational intervention on adult park use and PA behaviors in 3 low-income, racially diverse urban neighborhoods in Minneapolis, MN. Method: The study employed a household-level randomized controlled trial and collected baseline and follow-up data from 171 participants. Within each neighborhood, participants were randomized to an informational intervention or to a no-intervention comparison. Intervention households received monthly, neighborhood-specific newsletters about park-based PA opportunities, park program brochures, trail maps, and activity guides. Results: The average treatment effect of the newsletter intervention was positive yet moderated by respondent age. For a 20-year-old resident, treatment was associated with 0.97 (P < .05) additional park visits and 31.24 (P < .05) additional minutes of park-based PA over a 3-day recall period. For 40-year-old respondents, these positive effects are smaller at 0.36 (P < .05) additional visits and 4.66 (P < .05) additional minutes, respectively. Conclusions: An intervention to increase awareness about park-based PA opportunities and benefits increased self-reported park visits and in-park PA among adults who lived in low-income, racially diverse neighborhoods.
