The Influence of Hip Flexion and Isokinetic Velocity on Hamstrings-Quadriceps Strength Ratios in Healthy Females.

: Measurements of the concentric hamstrings-quadriceps strength ratio (Hc:Qc) are almost exclusively recorded in the upright, seated position (hip flexion 80-100°) on an isokinetic dynamometer at angular velocities ranging from 30°/s to 360°/s. Further, there is a scarcity of data examining Hc:Qc ratio in females. : To compare the effects of hip-flexion position (0°, 45°, and 90°) and isokinetic velocity (60°/s, 180°/s, and 300°/s) on knee-extension and knee-flexion torques and the Hc:Qc ratio of females.
