Abstract

The purpose of study was to resolve the effect of plyometric training and repeated sprint training on physical performance. The study was conducted on 41 subjects in two experimental groups (plyometric/repeated sprints training). Before and after the training program, subjects were subjected to diagnostic procedures that included standard test protocols. Results proved a statistically significant difference only after the plyometric training program compared to the repeated sprint group in countermovement jump (8.65% vs. 2.21%). In variable repeated jumps, an increased value was recorded (2.9% vs. 4.29%), like in sprint variables after the training program where certain trends of progress happened after the repeated sprint ability training and the specificity of the program (5 m = 0.89%, 10 m = 1.07% and 25 m = 1.35%), while plyometric training recorded unchanged values at 5 and 10 m, and a 0.27% improvement at 25 m. Stagnation of the 20-yard test was recorded in both groups. There was no difference between training programs in any variables of functional capacities, with similar measures recorded in repeated sprint ability. After six weeks of both training types, positive changes can be expected in explosive strength of lower extremities, increases in acceleration area, and maximum speed.

Highlights

The dynamics of sports games imply the constant repetition of high-intensity or maximal activities intersected by short periods of low-intensity activities or rest that are repeated continuously throughout the match or encounter [1]
Plyometric training and repeated straight-line sprint training programs resulted in a significant improvement in the results of countermovement jump, and there were differences between the groups after the training process
A statistically significant difference was obtained in the variable countermovement jump in the plyometric training group (8.65%), while in the other variables, there was a certain trend of improvement in individual abilities after 6 weeks of plyometric training and repeated straight-line sprint training

Summary

Introduction

The dynamics of sports games imply the constant repetition of high-intensity (submaximal) or maximal activities intersected by short periods of low-intensity activities or rest that are repeated continuously throughout the match or encounter [1]. The ability to resist fatigue and maintain the maximum intensity of activity throughout the match or encounter has proven to be a very important ability for team sports athletes. This ability is called repeated sprint ability (RSA). Football is an acyclic and intermittent sport, where short-lived high-intensity activities, such as 20 m sprints (sprint is defined as running above 25 km/h) and high-intensity actions such as counter-attacks, are intertwined with low and medium intensity activities (fast walking and jogging), and rests such as standing.
