Abstract

The aim of this study was to relate variables of countermovement jump (CMJ) and isometric mid-thigh pull (IMTP) with the performance of the repeat sprint ability (RSA) in professional soccer players, as well as to determine the differences in CMJ and IMTP results according to the RSA performance. 54 professional soccer players were evaluated (mean age= 23.1 +/- 5.1 years) in which the correlations were analysed through Pearson's coefficient. Subsequently, the group was divided into above (SM; N=27) and below (BM; N= 27) the median according to RSA performance in three variables and the students t-test for independent samples was used. Significant (p <= 0 .05) low to moderate correlations (r=-0.27;-0.30;-0.31; 0.46 y 0.42) were obtained in IMTP and CMJ variables with the RSA. Significant difference (p < 0 .05) from moderate to large in favour of SM were found in variables of power, contact
