The purpose of this study was to examine the isokinetic peak torque of plantar flexion and dorsiflexion in male and female. Seventy college students volunteered to participate in this study. Cybex-6000 dynamometer was employed in this study to examined the isokinetic concentric (CON) and eccentric (ECC) strength of ankle plantar flexion and dorsiflexion at 60, 120, 180, 240, and 300/s. Peak torques (PT) and peak torques relative to body mass for ankle plantar flexion and dorsiflexion were studied. The results indicated that ECC PT was greater than CON PT and plantar flexion PT was greater than dorsiflexion PT in both females and males. The ECC PT did not increase with increasing angular velocity. This study also showed that it was more reasonable to normalize PT relative to body mass when comparing the differences of strength between males and females.Downloads
