The participants are 6 professional female volleyball players of Shin-Yuan Junior High School;the average of their age, body height and body weight are 13.79±0.39age,159.76±4.24 cm and 56.33±3.67 kg.. The ball speed was estimated by the voice sensors which get the duration from the spike instant to dig instant. The statistics parameters of the study will be obtained through LabVIEW system(5000Hz), NI-DAQ 9205, accelerometer, EMG, voice sensors, and then take two different ball and speed as the independent variable, the premotor reaction time (PRT), motor reaction time (MRT), reaction time (RT), motor time( MT) and total reaction time( TRT) as the dependent variables to examine two-way ANOVA repeated measures. After discussing the outcomes of the study, the results are as follows: 1.The influence on the PRT、MRT、RT、MT、TRT when different directions to intercept the volleyball is below the statistical significant level. 2.The influence on the PRT、RT、MT、TRT when different ball speed to intercept the volleyball is above the statistical significant level. 3.The interaction does not exist between the influence of different ball direction and speed on the PRT、MRT、RT、MT and TRT . Conclusion: Speed is the main factor which effect dig-spike movement reaction time and movement time。 Jui-Hung Tu 涂瑞洪 2011 學位論文 ; thesis 58 zh-TW |
