Abstract

The aim of this study was to investigate asymmetry differences in landing techniques adopted by male and female athletes. Eight (4 male; 4 female) participants (age: 20.5 ±0.7 years, mass: 73.09 ±12.05 kg, height: 1.77 ±0.75 m performed drop landings from two heights (0.60 m & 0.90 m). Kinematic and kinetic data were collected during landing and used to calculated asymmetry for joint angles and kinetic variables. Significant (p<0.05) asymmetry was observed for all variables with larger kinetic asymmetry than observed in previous studies. Asymmetry of ankle flexion at touchdown reported for 7/8 participants may increase injury predisposition of one limb over the other. There was no clear gender difference for either the prominence or magnitude of asymmetry.
