ABSTRACT The aim of this study will verify the validity of Running Anaerobic Sprint Test (RAST) as a tool predictor of anaerobic capacity (MAOD) in football players. Twenty players in the category of a sub-20 team Presidente Prudente-SP, will undergo evaluation test anthropometric,incremental test (IT) to determine the maximal oxygen uptake (VO2max), MAOD and RAST. The tests will have a total duration of nine days. In the first anthropometric measurements will be taken and a IT to determine VO2max. Within five days after the players held ten submaximal efforts with intensities between 50 to 95% of VO2max. On the 7th day will be a supra-maximal effort until exhaustion at 110% VO2max. In the 8th and 9th days, will be performed six maximal efforts separated by 35m 10s range passive (RAST). The values of peak power and average and the rates of fatigue from the RAST in test and re-test situations will be compared and associated with the Student t test for dependent samples and Pearson correlation respectively. The Pearson correlation test is also used to verify the possible associations of the parameters from the RAST with MAOD. In all cases the significance level is pre-fixed for P <0.05.
