Findings reveal significant asymmetry in jump performance in elite male athletes, indicating injury prevention strategies may be necessary.

The study aims to investigate biomechanical asymmetries during single-leg drop jumps in elite male jump athletes.
Twenty elite male long and high jumpers performed single-leg drop jumps from 30 cm and 40 cm heights.
Data was collected using motion capture systems and force platforms for biomechanical analysis.
Kinematic and kinetic data including joint angles and peak ground reaction forces were measured.
The dominant leg showed greater ankle range of motion and hip joint moments compared to the non-dominant leg.
Significant differences in knee joint moments and reactive strength index were noted between jump heights.
Asymmetry indices indicated substantial differences in ground reaction forces and loading rates during impacts.

Li et al. (2025) studied this question.
