Purpose: To investigate the reaction time, the movement time of Kizami-Tsuki and Uraken-Uchi, and their correlation with the total response time, by conducting the research on 8 male and 8 female university elite karate players. Methods: The data was collected by using light stimulus、vibration switch、focus target/ body shape striking bag, electromyography and BIOPAC MP150. The result was analyzed by using Microsoft Excel 2010. Results: For male players, no significant differences in the reaction time, significant differences in the movement time (P=0.006), no significant differences in the total response time between Kizami -Tsuki and Uraken-Uchi; for female players, there were significant differences in the reaction time (P < .05), movement time (P < .05) and total response time (P < .05) between Kizami-Tsuki and Uraken-Uchi. Regarding the correlation of total response time between Kizami-Tsuki and Uraken-Uchi, both male players and female players reached significant positive correlation of medium degree, (r=0.487, P < .05) and (r=0.466, P < .05), respectively. Conclusion: For male players, the total response time for Kizami-Tsuki and Uraken-Uchi are the same. It is suggested that when providing strategical guidance, coaches can advise players to use Uraken-Uchi, which has a lafger strike range, as a scoring attack technique; as for female players, the Uraken-Uchi is slower than Kizami-Tsuki, and therefore, it is not suggested for female players to use Uraken-Uchi as a main attack technique during competition, but can increase the amount of Uraken-Uchi training in order to enhance the total time for this technique.
