RELATIONSHIP OF ISOKINETIC PEAK TORQUE WITH WORK AND POWER FOR ANKLE PLANTAR FLEXION AND DORSIFLEXION

Past research has analyzed the relationship of peak torque with work a nd power on lire muscles surrounding the knee with correlation coeffic ients being reported, ranging from .67 to .99. No studies to date have examined this relationship for muscles surrounding the ankle joint. T he purpose oi this study was to analyze the relationship of peak torqu e with work and power for the plantar flexor and dorsiflexor muscles o i the ankle. Isokinetic data were collected from 15 healthy subjects ( six males, nine females; mean age = 26.6 years) on an isokinetic dynam ometer across two trials at speeds of 30 and 120 degrees/sec. The resu lts of Pearson product moment correlations between peak torque to work and peak torque to power indicated correlation coefficients ranging f rom .81 to .97 for all speeds of testing and angular velocities. These findings suggest that peak torque is representative of work and power .
