| Abstract:
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 after landing, the purpose of this study was to determine the relationship between peak torques of lower limb muscles with dynamic stability. Fifteen healthy subjects (22±2yr) 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 analysed 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. The results of this study highlighted the role of quadriceps and dorsiflexors in stability after landing, in which can be used as criteria to assess and predict the possibility of injuries among athletes.
