| The primary outcome variable in this study is agility (9 x 4 meters). It is expected that implementing the PEP training program will produce significant improvements in this variable. Timepoint: The study variables will be measured at two time points: pre-test (before the start of the intervention) and post-test (after the completion of the eight-week training program). Method of measurement: This outcome assesses the agility of athletes through a 9-meter run test in four directions (9 x 4 meters). The aim of this test is to measure reaction speed, rapid change of direction, and muscle coordination. Specifically, the time recorded for running forward and changing direction on this track will be a measure of the athletes' agility.;The primary outcome variable in this study includes muscle power (Sargent jump). It is expected that implementing the PEP training program will produce a significant improvement in this variable. Timepoint: The study variables will be measured at two time points: pre-test (before the start of the intervention) and post-test (after the completion of the eight-week training program). Method of measurement: This outcome measures the explosive power of the athlete's lower body muscles through the Sargent Jump Test. In this test, the athlete must jump from a standing position to the highest possible height and record the distance of their jump. The purpose of this test is to measure muscular power and explosive power, which play an important role in sports performance, especially in disciplines such as volleyball.;The primary outcome variable in this study is dynamic balance (Y-Balance). It is expected that implementing the PEP exercise program will produce significant improvements in this variable. Timepoint: The study variables will be measured at two time points: pre-test (before the start of the intervention) and post-test (after the completion of the eight-week training program). Method of measurement: This outcome assesses an individual's | — |
