Abstract

We previously reported that 14 bouts of exhaustive high-intensity intermittent training [20 s periods of swimming while carrying a weight (14% of body weight), separated by pauses of 10 s] is the highest stimuli in terms of exercise training-induced glucose transporter 4 (GLUT-4) expression in rat epitrochlearis (EPI) muscles. In the present study, we found that the GLUT-4 protein content in the skeletal muscle of male Sprague-Dawley rats (age 5 weeks old; body weight 90-110 g) that underwent intermittent exercise training of 3 and 14 bouts of 20 s swimming for 5 days was increased over age-matched sedentary control rats by 75 and 71%, respectively, 18 h after the last bout of exercise. These results suggest that GLUT-4 content in rat EPI muscle increases dramatically after very short (60 s) and nonexhaustive high-intensity intermittent exercise training.
