The Effect of Plyometric Training with Boxes of Different Heights on the Development of Muscular Strength Components and Long Jump Performance

Abstract

The present study aimed to examine the effect of box height in plyometric training on muscle power and long jump performance. An equal-group experimental design was adopted in line with the research objectives. The study population comprised 100 male and female second-year students, A random sample of 20 students was taken and evenly split into two groups, each consisting of 10 participants. The first group performed plyometric training using a 20 cm box, while the second group trained with a 40 cm box. The results indicated that the group utilizing the 40 cm box achieved superior performance compared to the 20 cm box group in tests of five-step sprinting from a standing start and in long jump performance, particularly in the post-test assessments. Based on these findings, the researcher recommended incorporating sport-specific training programs rather than random training approaches. The study also emphasized the need to deepen coaches’ knowledge by offering specialized courses in exercise science. It recommended extending similar research to individual and team sports, exploring various age groups, and addressing both male and female participants.
