Capacity of Repeated Sprints and Aerobic Power in Soccer Players

Abstract

Of the determining factors for the performance of soccer players, the ability to support high-intensity actions followed by or with a short recovery interval are the most demanded in a soccer game. Thus, authors state that such recovery is directly linked to the supply of oxygen supplied to the metabolic systems during the recovery interval, however, little is known about the physiological mechanisms. Goal: The aim of this study is to verify the relationship between the ability to maintain speed in high-intensity actions (Capacity for Repeated Sprints or CSR) and aerobic power in soccer players. Methods: 14 athletes from the under-15 category were evaluated (172,3±5,8 cm; 66,4±8,3 kg) of a club from the A2 series of the Paulista Championship in two field tests, one to measure the maximum aerobic power (Max. VO₂.) and another that aimed to measure the capacity of repeated sprints (CSR).Results: There was no significant correlation (r=-0.45) between the PMA variables (Max. VO₂.) and the fatigue index (CSR), thus showing that one ability does not influence the development of the other.
