The porpuse of this study was to determine rate of validity between some of physiological variables of RAST and Wingate anaerobic power test in Iranian elite futsal players. 25 male futsal players of national team (age = 23.21±3.24, BMI = 23.35 ± 1 kg/m2, Body fat percent = 12.93 ± 1.84) participated in this study as subjects. RAST and Wingate 30 cycle test were performed for prediction of anaerobic power indices (Peak power, Low power, Mean power, Fatigue index) with 4 days apart. Heart rate and blood lactate were measured immediately, after 30 second and 120 second of tests. Data were analyzed by pearson correlation coefficient and paired sample t test, results showed that: there were significant correlation coefficient between peak power, mean power and low power (r=0.50 P<0.0l, r=0.52 P<0.01, r=0.49 P<0.0l) in these tests, but correlation coefficient between fatigue index was not significant (r= 0.15). No significant correlation coefficient in lactate concentration immediately, 30 second and 2 minute (rK).16, r= 0.08, r = 0.12) and also between heart rate immediately and 30 second after tests (r=0.35, r^0.22) between tests was found. But 2 minutes after two tests there was a significant correlation coefficient in heart rate (r= 0.39 P< 0.01). Although there was significant differences between peak, low and mean power, fatigue index and also heart rate immediately and 30 second after tests (P< 0.05) but no significant differences were found between lactate concentration that indicate the similar physiological load in both tests. Therefore RAST - which is more specific for futsal than Wingate test- be used for anaerobic assessment in futsal players.
