Abstract
The purpose of this study was to examine the effect of ankle position on knee flexor and extensor torque at 60 and 180°/s. Twelve female athletes had their dominant and non-dominant limb tested on a Cybex II + dynamometer (Cybex, Ronkonkoma, NY) under two conditions: with the ankle plantarflexed and dorsiflexed. Paired t-tests showed no statistical differences in knee extensor torque. Significant differences were noted in knee flexor torque at both 60 (P < 0.05) and 180 (P < 0.01)°/s with the greatest torque being seen with the ankle in the dorsiflexed position. These results suggest that ankle position affects knee flexor torque during open chain isokinetic movements.
