Relationship between Aerobic Capacity and Yo-Yo IR1 Performance in Brazilian Professional Futsal Players

Abstract

Purpose: To evaluate the relationship between aerobic and intermittent capacities in a team of professional futsal players. Methods: Fifteen futsal players from Brazilian first division (age: 25.95.1 yrs; height: 1.770.04 m, body mass: 74.376.02 kg) performed in random order a ramp test and the Yo-Yo intermittent recovery test level 1 (Yo-Yo IR1) at the start of the season for determination of maximum oxygen consumption (VO2max), peak running speed (Speak), and intermittent running ability. Results: Mean VO2max was of 57.256.35 mlkg-1min-1 with a Speak of 17.691.88 kmh-1. Yo-Yo IR1 performance was of 1,226282 m. There was no correlation between VO2max and Yo-Yo performance while Speak and Yo-Yo IR1 performance were correlated (r=0.641; P=0.007). Conclusion: From the current results, it may be suggested that both continuous and intermittent physical evaluations are necessary for obtaining a complete fitness profile of futsal players. The low Yo-Yo IR1 performance of Brazilian futsal players when compared to other elite team sport athletes warrants further investigation.
