Abstract

Shock absorption and reducing the RATE OF LOADING (ROL) during daily activities are considered as a reason for reducing the rate of injuries. Since, skeletal muscles utilize as shock absorber during weight bearing tasks, the purpose of this study was to examine the relationship between the maximum torques of lower extremity muscles with the ROL during SINGLE LEG DROP LANDING. 33 men subjects (23±2years and 73±3 Kg) from Tarbiyat Moallem University of Tehran volunteered in this study. MAXIMUM TORQUE OF LOWER EXTREMITY MUSCLES and the Ground Reaction Forces (GRF) were measured by the Biodex system and force plate (AMTI), respectively. The Pearson correlation used to analyses the data at the a£0.05 threshold. The mean torque of the quadriceps, hamstring, plantar flexors, dorsi flexors, invertors and evertors muscled were 2.70, 1.75, 0.77, 0.43, 0.43, 0.40 Nm respectively, and the mean ROL was 519/60 N/ms. Significant correlations wasn't seen between MAXIMUM TORQUE OF LOWER EXTREMITY MUSCLES with ROL. Due to results of this study it seem that quadriceps, hamstring, plantar flexors, dorsiflexors, invertors and evertors muscles have no role in decreasing the ROL in SINGLE LEG DROP LANDING.
