Comparison of results of maximum oxygen consumption in football players, by application of two tests for indirect field
Abstract
Among the motor skills required by a footballplayer, we highlight the ability of aerobic endurance which is important not only during the match but also after it, in the period referring to the players’ recovery. In order to measure the maximal aerobic power (VO2max) might be used field tests (indirect) estimating the VO2max. In this case, these tests are cost effective and provide conditions more close to the sport specificity.This study is aimed to compare the results of VO2max footballplayers by applying two indirect tests of distinct field. In this sense, the continuous run of 3,200 meters and the physical fitness test multi-stage (Yo-Yo test level 1) were employed. There were 25 athletes from a volunteer footballteam (category juniors), which were evaluated in both protocols, with a minimum interval of 48 hours between the sessions. No significant differences (p>0.05) between average values of VO2max for the two protocols were observed, once the continuous run test and the Yo-Yo one presented values of 58.13 ± 3.40 ml / kg and 55.57 ± 4.07 ml / kg, respectively. These results are in agreement with other studies reported in literature involving footballplayers, both junior and professionals ones. In addition, we also found high correlations (R= 0.76) between average values of VO2max obtained in both indirect tests, suggesting that both might be useful in order to estimate the VO2max of junior footballplayers.
