Abstract:
The purpose of this research was to examine the effects of balance exercise training on jump performance and balance in young female volleyball players. Eighteen volleyball players from the Bangkok Sport School were purposively sampled to participate in the research. The subjects were assigned into two groups of 9 players. So the subject divide to experimental group for 9 players (N=9) and 9 players (N=9) for control group. The experimental group had a supplementary balance exercise training before their regular training in the each day. While the control group had only the regular training. Both groups trained 3 day per week for a period of six weeks. The data of jump performance; Spike height, Block height and 3-Step Spike height and balance in characterize of postural stability test were collected before experiment and six week after training. The obtained data were analyzed in term of means, standard deviation. Pair sample T-test and the Wilcoxon Matched Pairs Signed-Ranks Test was used to check the difference between before and after training. Independent t-test and the Kolmogorov-Smirnov Two-Sample Test was used to check the difference between the two groups. The result indicated that: After six weeks of experiment, jump performance (3 position) in the experimental group were significantly better than those before experiment at 0.05 level. However there was no statistical difference on balance of the postural stability test both open and close eyes between before and after of experiment. After six weeks of experiment, jump performance (3 position) in the experimental group were significantly better than the control group at 0.05 level. However there was no statistical difference on balance of the postural stability test both open and close eyes between the two groups.
