CAPACITY OF REPEATED SPRINTS AND AEROBIC POWER IN SOCCER PLAYERS
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.

Abstract
Currently in football, one of the determining factors for the performance of footballlers is the ability to with stand high-intensity actions followed by a rapid recovery. Thus, some authors state that such recovery is directly linked to the supply of oxygen delivered to the metabolic systems during the recovery interval, however many studies did not succeed inproving such relationship.
Objective: The aim of this study is to assess the relationship between the ability to maintain the speed in high-intensity actions (or Repeated Sprints capacity CSR) and aerobic power in soccer players.
Methods: It was evaluated 14 athletes sub-category 15 (172.3 ± 5.8cm,66.4± 8.3kg)from a club in the Championship Series-A2 in two field tests, one to measure the maximal aerobic power (VO₂máx) and another aimed at measuring the ability of repeated sprints (CSR). Also, it was measured their height, body mass. Forthe statistical analysis, the Pearson correlation was used, adopting r>0.5as amoderate level ofcorrelation. It was used a term of free and informed consent with all researched participants.
Results: Through linear regression it could be observed that there is no significant correlation (r =-0.45) between PMA (VO₂máx) variables and the fatigue index (CSR), thus demonstrating that one ability that does not influence in the development of the other.
