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

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: 25.9±5.1 yrs; height: 1.77±0.04 m, body mass: 74.37±6.02 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 57.25±6.35 ml∙kg^-1∙min^-1 with a speak of 17.69±1.88 km∙h^-1. yo-yo ir1 performance was of 1,226±282 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.
