Abstract: Objective: to systematically evaluate the intervention effect of velocity-based training (VBT) on improving the maximal strength and explosive power in athletes so as to provide new evidence for strength quality training. Methods: randomized controlled trials (RCT) of VBT on strength quality were searched in CNKI, Web of Science, Google Scholar, Sport Discus, Pubmed and EBSCO from their inception till December 2021. Two researchers separately screened and extracted the literature, and assessed the bias risk of the included studies. The methodological quality of the included literature was assessed by Chochrane bias risk assessment tool, and statistical analysis on the 9 literatures finally included was made by Review Manager 5.4. Results: there were 6 studies on maximal strength, and 9 literatures on explosive power with a total of 290 subjects. (1) Compared with the traditional resistance training, VBT has great heterogeneity in improving maximal strength in athletes. After the sensitivity analysis by the elimination method one by one, the Meta analysis results were statistically significant (I2 =25%,P=0.25;SMD=0.65,95%CI:0.18-1.12,P=0.007, and tended to reach a medium effect when the combined effect was made; (2) VBT was statistically significant in improving explosive power in athletes (95%CI:0.42-1.07,I2=30%,SMD=0.74,P=0.00001), and tended to reach a medium effect when the combined effect was made. Research conclusion: VBT has certain effect on the maximum strength and explosive power of athletes.
