The purpose of this study was to investigate the performance and physiological responses to different repeated sprint tests (RST). Nineteen basketball players participated in this study voluntarily. Participants were randomly participated in straight-repeated sprint test (6x25m; SRST), 180° shuttle-repeated sprint test [6x(2x12,5m); SHRST] and 100º change of direction-repeated sprint test [(6x(25m) CODRST] with 25 seconds passive recovery durations. After 3 different RST, best sprint time (BST), total sprint time (TST), and percentage of performance decrement (PD%) were determined as performance responses. Participants' heart rate (HR) was continuously recorded before and during the tests to determine resting, mean and maximum heart rates (HRrest, HRmean and HRmax, respectively). In addition, rest (LArest) and maximal lactate (LAmax) and maximal rate of perceived exertion (RPEmax) responses were determined. Repeated measures of ANOVA indicated statistically significant differences in BST and TST values among 3 different RST (p<0,01). Bonferroni results showed that BST values at SRST were significantly better than the SHRST-BST and CODRST-BST values. On the other hand, SHRST-BST values were significantly better than CODRST-BST values. When TST values were examined, it was seen that SRST-TST values were significantly better than TST values obtained from the other two RST. PD% values on the other hand, were similar (p>0,05). In addition to these findings, there was no significant difference in HRmean, HRmax, LAmax and RPEmax measured during the tests (p>0,05). It can be concluded that, although there was no significant differences in physiological responses, performance responses in SRST were better than the other two tests.
