Positive Impacts of a Sport Intervention on Male Students of Color and School Climate.

A positive school climate is strongly associated with enhanced student outcomes. With the disengagement of Black and Latinx youth living in poverty being at an all-time high, participation in sport-based youth development (SBYD) programs may enhance school climate, while capitalizing on existing interests. The purpose of this study was to examine the impact of a SBYD intervention on male students of color and school climate.

The Relationship Between Physical Activity and Executive Functions Among Youth in Low-Income Urban Schools in the Northeast and Southwest United States.

The purpose of this study was to examine if physical activity is related to greater executive functions among youth in poverty. Executive functions (cognitive flexibility, inhibition, and working memory) and physical activity were measured in participants (N = 149) in the fifth to eighth grade from three schools located in high-poverty districts. Pearson correlations revealed a statistically significant correlation between physical activity and cognitive flexibility (r = .

The role of strength and power during performance of high intensity military tasks under heavy load carriage.

Objective: Previous research has investigated the physiological determinants of heavy load carriage while performing medium to long distance road marching, yet research examining the physiological underpinnings of high-intensity battlefield tasks is limited. This study sought to examine the role of strength and power during high-intensity combat tasks under heavy load carriage.

Methods: Eighteen recreationally trained men (mean±SD: age, 21±2 years; height, 172±6 cm; weight, 80±13 kg) participated in this study and performed an anaerobic combat course under 2 randomized experimental conditions; unloaded and loaded.

The relationship between muscle action and repetition maximum on the squat and bench press in men and women.

The relationship between muscle action and fatigue is not well understood, especially in terms of potential sex-specific differences. The purpose of this investigation was to determine whether a different number of repetitions could be performed on the individual muscle actions of the bench press and squat in men and women. Ten resistance-trained men (n = 10; age, 25.
