Alterations in Gait, Strength, and Power After Ruck Marching (SPARTAN)

The purpose of this study is to determine change in injury risk and performance variables in males and females after walking unloaded and carrying a load with two different distributions (high-pack placement and mid-pack placement) to identify differences in injury risk
