The skipping is the movement modeled after sprint running. The purpose of this study was to examine effects of skipping training on physical fitness, sprint ability and sprinting form. Nine non-athlete male university students participated in the training consisted of skipping exercises three days per week for eight weeks. The experiment was performed before and after the training period. The experiment was composed of measuring physical fitness and filming 100 m dash. Variables of analysis were: 1) back strength, vertical jump, stepping effeciency while sitting on a chair, 2) maximum anaerobic power, 3) isokinetic peak torque and isokinetic endurance of knee extension and flexion, and hip flexion, 4) 100m sprint record, and sprint record in each 20m sections, 5) running velocity, step frequency and step length, 6) thigh angle and angular velocity, and knee angle and angular velocity, 7) time for one step, support time and nonsupport time, 8) locus of ankle around trochanter major. Results were as follows: 1. Factors of physical fitness such as back strength, maximum anaerobic power and isokinetic peak torque were significantly improved after training. 2. 100m sprint record was significantly shortened, due to the increase of step frequency. 3. After training, the maximum running velocity was kept up for a longer period, and running velocity in 80 m to 100 m became remarkably faster. 4. After training, time for one step and nonsupport time were significantly shortened. 5. The knee lift during recovery phase became significantly higher. 6. The angular velocity of thigh of recovery leg became significantly faster. It is concluded that the skipping training for eight weeks improves sprint ability, sprinting form and physical fitness related to sprint running.
