| Research Abstract |
The present study aimed to determine the key muscles for better sprint running performance and the effective exercises for training the muscles. The results showed that the volumes of the gluteus maximus and hamstring muscles relative to the total lower limb muscle volume were significantly correlated to the sprint running performance. In a squat exercise, the greater activity of the gluteus maximus muscles was elicited when performed explosively without extra-load than at a steady-slow speed with barbell load. These results indicated that the gluteus maximus and hamstring muscles are the key muscles, i.e., to be trained, for better sprint running performance and that the explosive jumping exercise is better training than the steady speed barbell squatting exercise.
