Abstract

Bacground Leg muscle power is crucial for long jump performance, as insufficient explosive power limits maximum jumping distance. Therefore, specific training methods are needed to enhance these abilities. This research aims to analyze the application of single-leg hop and double-leg hop training methods on improving leg muscle power in long jump athletes. Methods a pre-experimental method with a non-randomized pre-test-post-test modified design, measuring samples before and after treatment. The research procedure consisted of pretest using the SBJ (Standing Broad Jump) test, treatment group division using the ordinal pairing technique, treatment stage with single-leg hop and double-leg hop training, and posttest using the SBJ test. Total sampling was used with 6 male athletes aged 15-20 years. Results show both training methods significantly improve explosive leg muscle power, with single-leg hop demonstrating superior effectiveness. For future research, it is recommended to extend intervention duration, explore various plyometric exercise modalities, and recruit larger, more diverse samples from different sports disciplines and age groups. Conclusions implementing rigorous control measures over external variables, including daily physical activity, sleep patterns, and nutritional intake through centralized training protocols or comprehensive monitoring systems, is essential to enhance internal validity and reliability of subsequent findings.
