Conditions

Healthy female adults occasionally involved in any kind of sport and/or physical activity without joint deformity, recurrent or recent injuries of the lower extremities, and history of neurological disease, vestibular, or visual disturbance Muscle activation, lower limb, single-leg landing, ground reaction force, risk of injury, landing test selection

Interventions

Only the dominant (strongest) leg was used as the landing leg throughout the study. In order to determine the strong and weak landing leg, participants performed a single-leg horizontal hop for distan

Experimental Behavioral

Single-leg drop landing (SLDL) and Single-leg jump landing (SLJL) testing intervention
