Abstract
The purpose of this investigation was to evaluate the differences among fatigue index and hamstrings-to-quadriceps (H/Q) peak moment ratios subsequent to an exhaustive running (TLimvVO2max) trial performed at maximum individual fatigue intolerance point using an alternative H/QFatigue approach rather than other conventional (H/QCR) methods of determining the hamstrings-to-quadriceps ratio under non-fatigued conditions. Thirty-seven male athletes from different sports participated to determine if there are differences due to the influences of fatigue and sports modality. VO2max, vVO2max, and TLimvVO2max were measured to determine maximum individual fatigue intolerance point with two preliminary test sessions. H/Q data analyzed were for angular velocities of 180°/s. H/QFatigue calculated using the moment developed in repetitions 48-50 was significantly greater than other conventional methods (p<0.001). Significant differences were apparent among new and conventional methods (H/QRight48,49,50:1.20–1.24 vs. H/QCR: 0.57–0.62; p<0.05) and (H/QLeft48,49,50:1.17–1.34 vs. H/QCR: 0.53–0.55; p<0.001), respectively. H/QFatigue ratios following an exhaustive exercise offer different information compared to conventional methods of determining the hamstrings-to-quadriceps ratio under non-fatigued conditions.
