Study of Wrist Isokinetic Power and Muscle Activation in Team Sports

Objective: This paper investigated wrist isokinetic strength and electrical muscle activations in volleyball, basketball, and handball players. Methods: Therefore, the sample consisted of 36 male volleyball (n=12), basketball (n=12), and handball players (n=12) over 18 years of age. Participants' weight and height were measured. Forearm muscle electrical activation was measured at an angular velocity of 30°/sec and 120°/sec to determine dominant wrist isokinetic strength. One-way analysis of variance (ANOVA) test was used to compare the groups. The Tukey test was used for post-hoc comparisons. Spearman's correlation coefficient was used to check the difference between the values. Results: There were significant differences in muscle activations at 120ºflex emg and 120ºext emg angles between the groups (p<0.05). The source of the difference was the volleyball group. There were significant differences in isokinetic strength values at all angles between the groups (p<0.05). The source of the difference was the volleyball and basketball groups. There was a positive correlation between 120º flex emg and 30º peak torque ext and 30º peak torque flex and 120º peak torque flex in the basketball group (p<0.05). Conclusion: In our comparison, the strength characteristics of the team branches we determined have a similar structure, but differences have been detected at the technical level depending on the characteristics of the branch. EMG and Isokinetic values differ in this sense.
