Abstract:
The purposes of this research were to investigate and to compare the effects of feedback upon short serving and long serving performance of badminton players. The samples were 60 students who registered SP ACT-BADMINTON course. They were tested for 4 groups matching by Lockhart and Mcpherson Wall Volley Test. They were divided into three experimental groups and one control group. The first experimental group trained serving with speech and action feedback from the trainer. The second experimental group trained serving with motion picture feedback from the trainer. The third experimental group trained serving with speech, action and motion picture feedback from the trainer. For the control group they trained serving without any feedback from trainer.They trained serving 60 minutes a day, three days a week, for 8 weight weeks in the training program. They were tested on badminton serving performance before, and after 4th and 8th weeks of the practice periods, by French Short Serve Test and Scott and Fox Long Serve Test. The obtained data were analyzed in term of means and standard deviations. The One-Way Analysis of Variance and Scheffe tests were employed to determine significant differences of the means in group and The One-Way Analysis of Covariance and LSD tests were employed to determine significant differences of the means between groups. The results were as follows: 1) Feedback training plus in serving training had effects on short and long serving performance of badminton players. 2) The three experimental groups had higher badminton serving performance than control group significantly at the .05 level. 3) The third experimental group can significantly perform better than the first experimental group, the second experimental group and control group at the .05 level.
