Abstract

Plyometric training is an exercise that relies on maximum muscle contraction which will increase if the active muscles are stretched appropriately and there is continuous (continued) movement. The aim of this research is to determine: 1) the effect of plyometrics depth jumps training on increasing movement speed and explosive power of athletes' leg muscles, 2) the effect of multiple box-to-box squat jumps plyometrics training on increasing movement speed and explosive power of athletes' leg muscles , 3) differences in the results of plyometrics depth jump and plyometrics multiple box-to-box squat jump training on increasing movement speed and explosive power in athletes' leg muscles. The population of this study were Physical Education students Class of 2020, Jabal Ghafur University, Sigli Pidie Regency aged 20-24 years with a sample size of 30 people who were divided into 3 groups (depth jump multiple box-to-box squat jump, and control) and each The group consists of 10 people. The method in this analysis uses comparative statistical methods with the Multivariate Analysis of Variance (Manova) test, while the data collection process is carried out by carrying out movement speed measurement tests using the 30 meter running test and measuring muscle explosive power. legs using the vertical jump test. Results: (1) Plyometric depth jump training has a significant effect on increasing movement speed and explosive power of athletes' limb muscles. The average change in movement speed was 0.44 m/sec or an increase of 7.29% and the average change in explosive power was 10.50 watts or an increase of 11.62%. (2) Multiple box-to-box squat jump plyometric training has a significant effect on increasing movement speed and leg muscle explosive power. The average change in movement speed was 0.98 m/sec or an increase of 15.54% and the average change in explosive power was 17.05 watts or an increase of 20.37%. (3) There is a significant difference between the results of plyometric depth jump and plyometric multiple box-to-box squat jump training on increasing movement speed and explosive power in athletes' leg muscles.

Abstract

This systematic review analyzed 50 studies from the Scopus database to determine the relative contributions of psychological, technical, and physical determinants to competitive sports performance, examining how these relationships vary across sport types, competitive levels, age, and sex. Utilizing a narrative synthesis approach in accordance with PRISMA 2020 guidelines, the review found that no single domain universally dominates; rather, performance relies on an integrated, context-dependent model. Specifically, physical fitness attributes proved most prominent in team and endurance sports, technical proficiency acted as a key mediator in open-skill and precision disciplines, and psychological constructs demonstrated the highest explanatory power in high-pressure, elite individual contexts. However, the validity and generalizability of these findings are constrained by several methodological limitations identified within the literature. These include a predominance of cross-sectional designs that limit causal inference, high outcome measurement heterogeneity that precluded meta-analytic synthesis, single-reviewer screening risks, and a notable demographic bias favoring male, adult, able-bodied team-sport samples over female, youth, and Para-sport populations. To advance the field, future investigations must prioritize longitudinal, multi-domain tracking designs using standardized measurement batteries and actively incorporate underrepresented athletic populations.
