Participation in empowering physical activities may increase self-efficacy and facilitate long-term engagement. This explanatory sequential mixed-methods study examined the relationship between physical activity empowerment, exercise self-efficacy, and engagement. Midwestern women (N = 147) aged 18–65, 90% white, completed an online cross-sectional survey that captured exercise engagement and self-efficacy for exercise. Participants entered up to five types of physical activities and ranked them from most to least empowering. Physical activities were coded by training type for statistical comparisons using independent t-tests. After survey completion, seventeen women completed a 30 min, 8-question semi-structured interview. Women ranked resistance training as the most empowering physical activity type (38%), followed by running (14%). Total and moderate-to-vigorous physical activity and self-efficacy for exercise scores did not vary between women empowered by cardiorespiratory or resistance training (i.e., total physical activity t(136) = 1.13, p = 0.11; moderate-to-vigorous physical activity t(136) = 2.42, p = 0.06; and self-efficacy for exercise t(136) = 0.66, p = 0.07). Themes identified from the interviews included: (1) women's physical activity participation barriers are gender-centric, (2) physical activity participation benefits extend beyond physical health, (3) some exercise types are more empowering than others, and (4) empowerment and enjoyment are closely related. Exploring empowerment in exercise may reveal mechanisms to facilitate exercise self-efficacy and engagement in physical activity. [ABSTRACT FROM AUTHOR]

Emerging evidence suggests that outdoor group exercise may reduce stress more than indoor group exercise because the outdoor environment provides unique mental health benefits. Stress leads to illnesses and diseases, but exercise mitigates harmful impacts. This study explored differences in perceived stress and outdoor physical activity participation among college students in an indoor or outdoor group exercise class. Data were collected pre-, mid-(after four sessions), and post-intervention (after eight sessions). Seventeen participants indicated an interest in the study, but 13 signed up. Participants completed a four-week group exercise intervention that met twice weekly in outdoor and indoor conditions. Mixed ANOVAs with Tukey post hoc tests determined between-group differences in perceived stress and outdoor physical activity levels. Partial eta-squared (X2 p) estimated effect sizes. Significant differences in perceived stress scores existed across time for the whole sample [f(2, 12) = 48.359, p < 0.001, X2 p = 0.890] and for the interaction between time and condition [f(2, 12) = 10.051, p = 0.003, X2 p = 0.626]. Post hoc analysis revealed that the outdoor group's perceived stress (p < 0.001) was reduced more than the indoor group post-intervention (p = 0.028). [ABSTRACT FROM AUTHOR]

United States Army soldiers must meet physical fitness test standards. Criticisms of the Army Physical Fitness Test (APFT) include limited testing of only aerobic and muscular endurance activity domains; yet, it is unclear what levels of aerobic and muscle strengthening activity may help predict performance in aspects of the new Army Combat Fitness Test (ACFT). This study explored relationships between baseline self-reported aerobic and muscle strengthening activities and APFT- and ACFT-related performance. Baseline participant data (N = 123) were from a cluster-randomized clinical trial that recruited active-duty military personnel (mean age 33.7 ± 5.7 years, 72.4% White, 87.0% college-educated, 81.5% Officers). An online survey was used for self-report of socio-demographic characteristics and weekly aerobic and muscle-strengthening physical activity behaviors. Participants also completed the APFT (2 min push-ups, 2 min sit-ups, 2-mile run) and ACFT-related measures (1-repetition maximum deadlift, pull-up repetitions or timed flexed arm hang, horizontal jump, and dummy drag). Bivariate logistic regression found greater aerobic and muscle-strengthening activity predicted better APFT performance, while better ACFT-related performance was predicted by greater muscle-strengthening activity. Although our data are mostly from mid-career officers, command policies should emphasize the new Holistic Health and Fitness initiative that encourages regular aerobic and muscle-strengthening physical activity for soldiers.
