Implication

Comparative study reveals experience-dependent differences in joint flexion and landing duration across drop heights in male athletes, highlighting tailored impact absorption strategies.

Key Points

To determine how impact velocity and athletic landing experience alter lower-extremity biomechanical strategies and shock absorption during drop landings.
Assessed male collegiate gymnasts and recreational athletes performing drop landings from three distinct heights.
Recorded lower-extremity kinematics using high-speed film and measured ground reaction forces simultaneously via a force plate.
Increases in impact velocity caused statistically significant elevations in impact force, joint angular velocity, and joint flexion, with the exception of ankle joint flexion.
Gymnasts and recreational athletes shared general patterns of velocity-dependent adjustments but differed significantly in degree of joint flexion, total landing phase time, and relative adaptation magnitudes.
