The Effect of Outdoor and Indoor Group Exercise Classes on Psychological Stress in College Students: A Pilot Study with Randomization

International Journal of Exercise Science 16(5): 1012-1024, 2023. 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 (η2p) estimated effect sizes. Significant differences in perceived stress scores existed across time for the whole sample [f(2, 12) = 48.359, p \u3c 0.001, η2p = 0.890] and for the interaction between time and condition [f(2, 12) = 10.051, p = 0.003, η2p = 0.626]. Post hoc analysis revealed that the outdoor group’s perceived stress (p \u3c 0.001) was reduced more than the indoor group post-intervention (p = 0.028)

Is Self-Efficacy for Exercise Predictive of Leisure-Time Physical Activity among Police Officers? A Pilot Study

Leisure-time moderate to vigorous physical activity (MVPA) is an essential indicator of overall health. Given the physical nature of police work, it is critical to understand variables that predict officers’ engagement in MVPA. Self-efficacy for exercise (SEE) may be a variable directly related to officer engagement in MVPA. This study aims to examine the relationship between SEE and MVPA among police officers in two departments in a small urban midwestern city. A cross-sectional survey was completed by 32 officers (male = 26, female = 6; aged 35.9 ± 7.1 years). Regression analysis was performed to explore how anthropometric and demographic variables affected SEE’s ability to predict MVPA. When combined with SEE, the model containing age had the highest predictive ability of officers’ engagement in MVPA (p = 0.011; adjusted R2 = 0.2145). Adding other predictor variables reduced the model’s ability to predict MVPA. SEE significantly predicted officers’ engagement in MVPA when age was added as a predictor variable. SEE alone could not predict officers’ engagement in MVPA, but adding other variables besides age to the model did not improve its predictive ability in our study. Police organizations should explore wellness initiatives that increase officers’ SEE and promote MVPA, particularly as officers age

The Effectiveness of a CrossFit Training Program for Improving Physical Fitness of Young Judokas: A Pilot Study

The aim of this pilot study was to examine the effectiveness of a CrossFit-based training program to enhance the general and sport-specific physical fitness of 10–12-year-old judokas. The study was conducted between September 2021 and February 2022. The pedagogical research experiment was designed to be one complete, annual macrocycle (September–June). The current study presents mid-point data. Twenty male participants (3 years average sports experience; age = 11 ± 0.64 years) were randomly assigned to one of two groups: CrossFit-based training (experimental, n = 10) and traditional training (control, n = 10). Baseline testing was conducted by the researcher and included tests for motor skills and general physical fitness domains including Sweden wall pull-ups and leg raises, push-ups, long jump, squats, burpees, shuttle run, and forward rolls. Judo-specific tests included O Soto Gari and O Goshi throws. CrossFit-based training was implemented twice per week for 15–20 min in the experimental group after usual training. The control group completed traditional methods of physical fitness training for judokas with the same training load regarding time. Experimental group participants significantly improved on leg raises (p < 0.01), push-ups (p < 0.05), and shuttle run (p < 0.001); the control group improved their shuttle run (p < 0.001). Only the experimental group improved on the O Soto Gari (p < 0.01) and O Goshi throws (p < 0.05). Results showed that the use of CrossFit-based trainings had a positive effect on 10–12-year-old judokas’ speed-strength abilities, speed-strength endurance, and muscular strength

A Mixed-Methods Study of Women’s Empowerment through Physical Activities: Relationships with Self-Efficacy and Physical Activity Levels

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

Anticipatory Anxiety, Familiarization, and Performance: Finding the Sweet Spot to Optimize High-Quality Data Collection and Minimize Subject Burden

Accurate baseline data are essential for researchers to determine an intervention’s effects yet may be affected by anticipatory anxiety and assessment familiarity. Familiarization sessions help establish accurate baseline data. High-intensity functional training (HIFT) elicits performance outcomes based on constantly varied workouts. It is unclear how familiarization affects anticipatory anxiety and workout performance among HIFT novices. Familiarization was hypothesized to decrease anxiety and improve workout performance. Sixteen college-aged subjects (62.5% women, 20.2 ± 1.14 years) completed one introductory and four sessions of the same workout. All subjects were recreationally trained with no HIFT experience. State and trait anxiety were assessed at the first session. During the workout sessions, state anxiety (SQALS) was assessed upon arrival at the gym (SQALS 1), after learning the workout protocol (SQALS 2), and when the workout concluded (SQALS 3). A significant main effect of the number of previous sessions on workout performance was observed (p = 0.011). A repeated-measures ANOVA showed a main effect of time on SQALS 1 (p < 0.001), SQALS 2 (p < 0.001), and SQALS 3 (p < 0.001). Our results suggest implementing two familiarization sessions for our HIFT-based workout was sufficient to decrease anxiety and establish a baseline measurement. Future research should examine if this remains true for other types of HIFT-based workouts

Baseline Physical Activity Behaviors and Relationships with Fitness in the Army Training at High Intensity Study

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
