Abstract

The purpose of this study was to analyze the effect of landing strategies on the landing kinetics during loaded jumps. Ten male participants performed counter movement jumps with 50% body weight (BW) additional load using four different landing strategies. Landing strategy referred to peak knee joint flexion during landing. Peak vertical force increased up to 50% with decreasing knee joint flexion during landing. No changes were found regarding peak joint moments and powers. Total lower limb joint work increased up to 83% with increasing knee joint flexion during landing. The results suggest that energy dissipation during loaded landing is shifted from active (muscle-tendon system) to passive (skeletal system) as peak knee flexion decreases during landing, resulting in mechanical stress on different body tissues depending on the landing strategy.
