Comparação entre os limiares ventilatórios e o consumo máximo de oxigênio de atletas de futebol e futsal em teste progressivo de esteira.

Abstract

The main objective of this study was to compare ventilatory thresholds and maximal oxygen consumption among soccer and futsal athletes, in order to identify the level of physical effort required in each modality. The cross-sectional study evaluated 57 male athletes, with a mean age of 25,30 years (±5,17), being 30 soccer and 27 futsal athletes from two professional level teams from the cities of Santa Cruz do Sul-RS and Venâncio Aires-RS, respectively. The evaluations were carried out in the preseason period in both teams. In order to evaluate the cardiorespiratory variables, was used the ergospirometric test using the maximum Bruce protocol in treadmill. The ventilatory thresholds were identified by the visual-graphical method with the analysis performed by three experienced evaluators and the maximal oxygen consumption by the highest oxygen consumption obtained in the effort. The results indicated similar maximal oxygen consumption values in both groups of athletes, however the ventilatory thresholds occurred earlier in futsal athletes as well as they stayed longer around the anaerobic threshold, demonstrating to tolerate higher effort intensities.
