This thesis has investigated the effects of training on the maximum sprinting velocity of experienced male sprinters. Elements of the running stride and capability of the leg to produce torque and power were also analyzed.High speed cinematography was used to determine the subjects' sprinting velocity, stride length, stride frequency, support time, flight time, ratio of support time to stride time, angle of lower leg at take-off, and angle of lead thigh at take-off. Velocities of the upper and lower legs were measured at three points in the stride. Leg strength and power were measured on a Cybex Leg Press, an isokinetic device.Of the 23 measurements taken, only 2 showed significant changes after training: increased flight time and decreased ratio of support time to stride time. These changes suggested a possible increase in the efficiency of the running stride. |
