The effects of Core Balance Exercises on Trunk Isokinetic Muscular Function and Balance abilities and Posture Stability in Male College Volleyball Player

This study aimed to provide fundamental data contributing to male college volleyball player trunk isokinetic muscular function and balance abilities and posture stability in male college volleyball player by core balance exercises on trunk isokinetic muscular function and balance abilities and posture stability. Twenty-two voluntary subjects (11 exercise, 11 non-exercise) with an understanding toward the aims of this study were selected and their trunk isokinetic muscular function and balance abilities and posture stability, before and after the core balance program, were measured. As for the trunk isokinetic muscular function, there were significant differences between pre- and post-values in the exercise group after completing the core balance exercises program. In the aspect of comparisons between post-values in both groups, there were significant improvements in only the exercise group. As for the static balance ability, there were significant differences between pre- and post-values in the exercise group. Meanwhile, in the aspect of comparisons between post-values in both groups, there were significant improvements in up(U), right(R), down(D), and left(L) of the exercise group. As for the posture stability, there were significant differences between pre- and post-values in the exercise group. Meanwhile, in the aspect of comparisons between post-values in both groups, there were significant improvements in of the exercise group.
