The purpose of this study were to examine the effects of gravity and sport on the hamstrings-quadriceps strength relationships. The peak torques at four speeds of isokinetic exercise (60, 180, 240, 300°/sec) were determined for 20 male college track athletes, including 10 sprinters and 10 distance runners. The runners were tested on a Cybex® II isokinetic dynamometer. Peak torque measurements were corrected for the effects of gravity. Results of the present study showed that: 1) the effects of gravity significantly alters the hamstrings to quadriceps ratio at all velocities, and 2) there is no statistically significant difference in the hamstrings-quadriceps strength ratios between the two groups of athletes except at 300°/sec. At that speed, sprinters had a higher ratio than distance runners.
