摘要：The aims of this study were on the one hand, to describe the performance in a laboratory cardiovascular test and in a repeated sprint ability (RSA) test, and on the other, to analyze the association between the results obtained in both test. Twelve high-standard soccer referees (1st, 2nd y 2nd B Divisions, 28,8±5,1 years, 73,2±6,6 kg, 1,8±0,1 m and 22,82±1,38 kg·m-2) participated in this study. Soccer referees obtained 59,50±4,56 ml·kg-1·min-1 of maximum oxygen consumption (VO2max). Mean time (RSAMedia) spent to perform the repeated sprints in 15 and 30 m distances was 2,54±0,09 s and 4,43±0,14 s, and total time (RSATotal) was 15,26±0,53 s and 26,60±0,82 s, respectively. Fatigue indexes (RSASdec and RSACambio) in 15 and 30 m distances were 2,25±1,05% and 3,33±1,59%, and 3,45±2,92% y 6,31±4,63%, respectively. Positive associations were found between cardiovascular variables and RSA time variables. On the other side, oxygen consumption at ventilatory threshold 1 (VT1) and ventilatory threshold 1 (VT2) and fatigue index (RSASdec) correlated negatively. Despite a higher cardiovascular capacity in soccer referees may generate a negative effect on the time spent in RSA, it also minimize the fatigue during repeated sprints. Physical trainers should focus the training of soccer referees on the cardiovascular capacity and they should implement acceleration specific training.
