The purpose of this study was to determine the relationship of leg strength and anthropometric dimensions with sprint speed in women track athletes. Ten sprinters were tested for isokinetic leg torque at 3 speeds (60, 180 and 360 deg/s) and sprint times at 10 and 30m. The correlation between 10m and 30m sprint (r = 0.79) was significant. Individual regression lines were constructed to estimate sprint times from the log of the isokinetic torques. The slopes were moderately correlated with 10m (r = 0.54, SEE = 0.08 s, CV = 4.2%) and 30m (r = 0.54, SEE = 0.33, CV = 7.2%). Predicted sprint times were not significantly different from actual times (p>0.89). Women sprinters who can maintain greater leg extension torques at greater velocities are likely to be better sprinters.
