Publication: Sex-related differences in joint-angle-specific hamstring-to-quadriceps function following fatigue

Research Impact: An imbalance between hamstring and quadriceps function can predispose an athlete to injury, therefore, it is important to understand functional ratios between hamstrings/quadriceps (H/QFUNCT) at different joint angles, angular velocities and how this may be influenced by sex. Fatigue leads to reductions in H/QFUNCT ratios at all joint angles and velocities, and this is exacerbated in females. Fatiguing exercise has the greatest impact on H/QFUNCT ratios at greater angular velocities and closer to full knee extension. Practitioners should consider screening for H/QFUNCT ratios following fatiguing exercise to help identify athletes at higher risk of injury.
