The effects of sprint training were examined on the sprint ability and such important factors of physical fitness as agility, strength and power. Six non-athlete male university students aged 19-20were engaged in the training program consisted of 50 m and l00m sprint running 3 times a day, 3days per week, for a period of l0 weeks. Fifty-and a hundred-meters sprint record, step length, step frequency, stepping efficiency while sitting on a chair, back strength, leg extension strength, leg flexion strength, vertical jump performance and ergonomic power were measured before and after the training period. The results were as follows : 1) While training effect was significant in 100m sprint record (p<0.05), it was insignificant in 50m sprint record, step length and step frequency. 2) No significant change was found in a test for agility, i.e., stepping efficiency while sitting on a chair. 3) Remarkably large training effects were found in back strength (p<0.05), leg extension strength (left and right: p<0.01) and leg flexion strength (right: p<0.01, left: p<0.05), indicating increased muscle strength. 4) Training effects were significant in the ergonomic powers exerted under relatively heavier work loads (6 and 7kp: p<0.05 and p<0.01, respectively); while insignificant under relatively lighter work loads (3, 4, 5kp) and also at the vertical jump. It is concluded that sprint training of the non-athlete male university students not having special physical training significantly improved 100m sprint record. This training effect is due to the increase in the muscle strength of leg and back, and the improvement in the power output exerted under relatively heavier work loads.
