Table 3: Descriptive statistics of kinematic parameters of the UHCJ20m, MRLS20m, and MRFS20m tests. that did not provide new information about the correlation between the set of predictor variables and the criterion variable, a stepwise regression analysis was used. Stepwise regression analysis identified two of four statistically significant kinematic parameters that contained the most information about correlation with the criterion variable (Table 4). The entire set of predictors showed correlation values with criterion (R = 0.371; R\({}^{2}\) = 0.138). The variables SL (\(p\) = 0.008) and CT (\(p\) = 0.043) were the only ones that significantly correlated with 100 m sprint success, whereas the other variables did not contain any new information.
