CHRONIC EFFECTS OF PLYOMETRIC TRAINING ON AEROBIC FITNESS IN MEN STREET RUNNERS

Abstract

Introduction: Running is a sport that has grown exponentially in Brazil and several studies have shown the importance of muscular power and that training with jumps is a method that can contribute to improving this physical capacity and better performance in the sport. Objective: to investigate whether plyometric training applied to street runners aged between 30 and 45 years, for ten weeks, would bring improvements in Maximum Oxygen Volume (VO₂max). Materials and Methods: the sample consisted of 16 men who practice street running, thirty-four visits were carried out with 48 hour intervals between them. In the first two visits, the following procedures were carried out: a) filling out the TCLE and the pair – Q; b) anthropometric measurements; c) experimental familiarization protocol Yo-yo intermittent recovery test level 1 (Yo-YoIR1). In the remaining visits, the following were carried out: 1) intervention protocol (visits 3 to 33); and b) Yo-YoIR1 retest (visit 34). Results: In the analysis carried out, no significant differences were observed in VO₂max when comparing the experimental groups. Conclusion: it is suggested that running athletes, coaches and physical conditioning professionals use PT when the intention is to consider the use of the method as a training strategy that aims to improve and perfect the efficiency of physical quality power, since it was not observed improvements in VO₂max.
