Department of Kinesiology, McMaster University, Hamilton, Ontario, Canada L8S 4K1 Our purpose was to examine the effects of sprint interval training on muscle glycolytic and oxidative enzyme activity and exercise performance. Twelve healthy men (22 ± 2 yr of age) underwent intense interval training...
