摘要：Crisp AH, Verlengia R, Sindorf MAG, Germano MD, Cesar MC, Lopes, CR. Time to Exhaustion at VO2 Max Velocity in Basketball and Soccer Athletes. JEPonline 2013;16(3):82-91. The purpose of study was to compare the maximum distance traveled (Dmax) and time to exhaustion (Tlim) at the minimal velocity that elicits VO2 max (vVO2 max) in basketball and soccer athletes. Twenty-six basketball and 27 soccer players performed a maximal cardiopulmonary exercise test (CPETmax) to determine maximal oxygen uptake (VO2 max), the first ventilatory threshold (VT1), velocity of VT1 (vVT1) and vVO2 max, the time to exhaustion at vVO2 max to determine Tlim and Dmax, and the kinetics of blood lactate removal at pre, 0 (immediate), 3, 6, 9, 15, and 20 min after time to exhaustion at vVO2 max test. The findings indicate that the variables of CPETmax were significantly superior (P<0.05) for soccer athletes. On the other hand, the Tlim was significantly higher (P<0.05) for basketball athletes (318.0 ± 98.9 sec) versus the soccer athletes (255.3 ± 86.6 sec). There was no significant difference for the variable Dmax (basketball: 1344.7 ± 415.4 m; soccer: 1228.3 ± 369.6 m). There was no significant difference between the groups on the kinetics of blood lactate removal and peak blood lactate value. There was a moderate correlation of Tlim with VO2 max (r = -0.44), vVO2 max (r = -0.55), vLV1 (r = -0.43), and peak lactate (r = 0.47) only for soccer athletes. The findings suggest that these differences are likely to be due to physiological characteristics inherent in each sports modality. Soccer athletes had superior physiological parameters of aerobic metabolism while the basketball athletes had higher Tlim.
