摘要

The purpose of this study was to probe the effect of different oncoming ball velocity and stimulus-response compatibility with return balls on reaction time related parameters for young tennis players. The participants contain 10 senior high school and 10 junior high school tennis players. The age, training year, height and weight of junior high participants (8 male, 2 female) are 13.72 ± 0.88 years, 2.60 ± 1.70 years, 163.30 ± 5.98 cm, 55.00 ± 12.40 kg. The age, training year, height and weight of senior high participants (10 male) are 17.13 ± 0.86 years, 4.90 ± 2.13 years, 170.80 ± 2.78 cm, 64.10 ± 5.99 kg. The dependent variables of this study are ball velocity and stimulus-response compatibility, the dependent variables are reaction time related parameters: reaction time (RT), pre-motor reaction time (PRT), motor reaction time (MRT) and movement time (MT).The signals from infrared sensors, electromyographic sensors, accelerometer and acoustic sensors were acquired through NI DAQ card and analyzed by LabVIEW (5000 Hz) to determine RT, PRT, MRT and MT. Using the calculating system SPSS.12 to have a 2-way ANOVA to test, the results of the study were as follows: 1. There was no interaction between different ball velocity and compatibility on reaction time related parameters. 2. There was significant difference on PRT, RT and MT under different ball velocity, but there was not on MRT. 3. There were no significant differences on reaction time related parameters under different compatibility. The dominate influence factor for reaction time related parameters is ball velocity. For the future, in order to probe the reaction time parameters differences between different skill performance levels of tennis players, the more complete experimental design is needed. And to simulate the training situation that similar real competition training situation is also needed for training efficiency.
