Development of Lower Limb Muscle Strength through the Implementation of a Plyometric Program for 7th Grade Students

Abstract

The aim of this research is to investigate the effect of plyometrics on the development of explosive strength in the lower limb muscles of 7th-grade students (13-14 years old). Two classes were selected for the study: one experimental group with 24 students (8 female and 16 male) and one control group with 24 students (12 female and 12 male). A plyometrics program was implemented for 12 weeks. From the initial test to final test, both groups showed improvements to all tests applied, except for the drop jump test for the control group. Analysis of data between the groups shows improvement in favor of experimental group to the 10m and 20m sprint tests, standing long jump, counter-movement jump and drop jump. In conclusion, the implementation of the program significantly influenced the development of explosive strength.
