Purpose: To probe the effects of 8 weeks reaction time training on pre-motor reaction time, motor reaction time, reaction time and movement time of elementary students’ table tennis movement. Methods: The participants were 12 excellent players of Guei-Ren Elementary school’s table tennis team in Tainan City. The average of their age was 11.41±0.51 years, the height was 143.3±3.39 cm and the weight was 34.5±2.86 kg. There were 6 players in control and expetimental group respectively. The Labview programming language was the main plateform to integrate the devices to got the data. The main experimental devices were DAQ Card, (National Instruments USB 6211 DAQ, 250KS/s,5000 Hz) ower supply, table tennis serving machine and brightest LED lamps,EMG system and accelerometer system (5000 Hz). The parameters contain premotor reaction time, motor reaction time, reaction time and movement time. It were tested control group with experimental group by independent t-test (α =. 05). Results: There were significant difference in the effects of premotor reaction time, motor reaction time, reaction time and movement time of table tennis players’ return movement after 8 weeks reaction time training. Conclusions: After 8 weeks reaction time training, the performance level of table tennis players was promoted.
