RESUMO

INTRODUCTION: This meta-analysis examined the effects of plyometric training (PT) and resistance training (RT) on lower limb explosive power and speed quality in athletes, including lower limb jumping and short-distance sprinting abilities. EVIDENCE ACQUISITION: Empirical studies investigating the PT and RT effect on lower limb explosive power were identified using the PubMed, Web of Science, Embase, EBSOC, and CNKI databases. Heterogeneity testing and potential publication bias assessment were conducted using STATA 15 and Review Manager 5.4. EVIDENCE SYNTHESIS: There were 20 articles included, involving 457 participants (230 in the PT group and 227 in the RT group). The meta-analysis results indicated no significant difference in countermovement jump (CMJ) between PT and RT groups (SMD = -1.03; 95% CI = -5.20 - 3.14). Additionally, no significant differences were found between the two training methods for standing long jump (SLJ) (MD = -0.04; 95% CI = 0.00 - 0.09), squat jump (SJ) (MD = -0.79; 95% CI = 1.79 - 0.22), 10-m sprint (MD = -0.02; 95% CI = -0.06 - 0.02), and 30-m sprint (MD = -0.02; 95% CI = -0.15 - 0.11). However, PT and RT comparisons revealed a significant difference between the 5-m sprint (MD = -0.03; 95% CI = -0.05 - 0.00) and the 20-m sprint (MD = -0.05; 95% CI = -0.09 - 0.01). CONCLUSIONS: This meta-analysis demonstrated that relative to RT, PT significantly improved the sprinting abilities of athletes at 5-m and 20-m distances. However, no significant differences were observed in sprinting at 10 and 30 meters, CMJ, SLJ, and SJ, indicating consistent effects of PT and RT on jumping performance.
