The purpose of this study was to investigate the gender difference and correlation in eccentric strength and dynamic balance exercises.
Thirty-four healthy adults (17 males and 17 females) with a mean age of 21 participated in this study. The angular velocity of isokinetic equipment was set to 90 degrees with the eccentric peak torque values of knee flexion and extension, ankle dorsiflexion and plantar flexion recorded while giving verbal comments. Electromyography(EMG) which was used to measure muscle activation during exercise was attached to rectus femoris, biceps femoris, tibialis anterior and gastrocnemius muscles respectively. A total of 5 movements including side step, calf raise, step down, lunge, and chair sit/one-leg squat was performed.
According to muscle values, there was a significant difference in eccentric peak torque between sexes(p<.05). However, there was no significant difference in muscle activity between sexes in dynamic balance exercise(p>.05). Both eccentric peak torque and dynamic balance exercises displayed a positive correlation(p<.001).
A better understanding of the correlation between eccentric strength and dynamic balance may be helpful in creating effective balance training interventions for athletes and those in need of balance stabilization.
