INTRODUCTION: Providing reaction and visual feedback during sports training has been shown to improve reactive performance. Velocity-based resistance training Resistance training has also been proven to enhance rapid strength. However, whether velocity-based resistance training with reaction and visual feedback is a more effective training method for elite athletes remains to be verified. The aim of the present study was to identify which of three training methods leads to the best training effects on sport performance in elite Taekwondo athletes. METHODS: Eight-teen elite taekwondo athletes were recruited and divided into free -weight resistance training group (FWRTG, n=6), velocity based resistance training group (VBRTG, n=6), VBRT with reaction and feedback group (VBRT-RFG, n=6). All subjects completing 6 weeks,3 times a week training program which consisted of 3-5 sets of 10-20repetitions. Intensity was 30-50%1RM. Mean propulsive velocity (MPV) were monitoring during VBRT and VBRT-RF. Beside, 15% and 20% of Velocity loss were standard for arranging longer rest periods or stopping training. Before and after training, velocity, power, RFD, kicking ability were collected for statistical analysis. Data of baseline and percentage of training effects among groups were analyzed with Analysis of Variance, ANOVA and Bonferroni post hos test. The Paired Samples t-Test was used to compare the difference between pre-test and post-test. The level of significance was set at * = .05. RESULTS: FWRTG showed a significant enhancement effects in MPV of 40%1RM, MPV of 50%1RM, height of three times CMJ, strength of three times kicks (p
