✦ Synopsis
The jump-landing is movement that repeatedly used in the sports activities. Successful landing require the stability to prevention of injuries. With respect to muscle strength role in stability from landing, the purpose of this study was to determine the relationship between peak torque of lower limb muscles with dynamic stability. 15 healthy subjects(age=22±2) participated in this study. The peak torque of muscles (quadriceps, hamstrings, dorsiflexors, plantarflexors, evertors and invertors) assessed by the Biodex system. The ground reaction forces (GRF) in the medial-lateral and anterior-posterior directions measured using force plate (AMTI). The stability of the subjects analyzed by the Time To Stabilization(TTS) method. Significant correlation seen between quadriceps, hamstrings, dorsiflexors, plantarflexors, and invertors muscles peak torque with time to stability of anterior-posterior direction. Although we found significant correlation between quadriceps, dorsiflexors with time to stability in medial-lateral direction, it seems that quadriceps muscle has important role in stability at landing.
