The purpose of this study was to investigate the effects of different distance forward jump among the healthy control, coper, and CAI groups. Participants were asked to perform a single-leg forward hop and followed with a single-leg landing on the force plate. The forward jump distance was standardized to 50%, 100%, and 150% of leg length from the center of the force platform. Results from the current study indicated two major findings: the CAI group were use greater ankle external rotation to avoid the possibility of ankle sprains during single-leg landings. During descending phase of landing, the CAI group demonstrated a greater medio-lateral GRF compared to healthy group. Our findings indicated that different landing strategy of ankle joints exist among 3 groups.
