Little is known regarding the types of physical activity interventions most effective in supporting the mental and physical health of woman-identified survivors of gender-based violence. This study measured the experiences of 56 participants who participated in a 14-week trauma-informed, noncontact boxing program once per week for 90 min. Participants completed measures of health-related outcomes including physical and mental health, quality of life, mastery, resilience, self-esteem, physical self-efficacy, social conflict, and financial strain at baseline, program midpoint, and program end. Analyses of variance showed significant improvements for all indicators measured except financial strain, demonstrating viability and effectiveness of this program.

Plyometric exercise induces an overall anabolic osteokine response favoring osteoblastogenesis over osteoclastogenesis in both boys and girls although the timeline and mechanism(s) may be different.

METHODS:One hundred twenty-nine female F 2 mice derived from high physically active (SWR/J) and low physically active (DBA/2J) F 0 progenitors were individually housed in cages with running wheels and magnetic sensors. Daily duration (min/d), daily distance (km/d) and weekly BW measurements (g) were recorded from nine weeks of age until the end of life. Average daily speed (m/min) was calculated. RESULTS:Body weight increased with age (p<0.0001). Daily duration increased from age 20 to 44 weeks and decreased thereafter to 88 weeks of age (p<0.0001), while average daily running speed declined with age (p<0.0001). Across the lifespan, we found a significant correlation between BW and duration (p<0.0001, r=-0.117, r 2 =0.014) and between BW and speed (p=0.005, r=-0.060, r 2 =0.004), with week-specific correlations for these variables both early and late in the lifespan. CONCLUSIONS:The significant correlations of speed and duration to BW early and late in the lifespan suggests differing influence of activity on BW depending upon the age of the mouse.
