Basal HGP was lower following 7 days of exercise: 3.17 ± 0.43 vs. 2.54 ± 0.26 mg·kg−1·min−1 (P = 0.05; Fig. 2). HGP during the 40-mU insulin stage was also decreased following exercise: 1.15 ± 0.41 vs. 0.46 ± 0.20 mg·kg−1·min−1 (P = 0.03; Fig. 2). Compared with basal, the exercise program resulted in greater suppression of HGP during the 40-mU stage (−69.1 ± 9.1 vs. −84.5 ± 4.3%; P = 0.05). HGP was completely suppressed during the 1,000-mU stage both before and after the exercise program (Fig. 2). These findings provide evidence for an increased insulin suppression of HGP after the 7 days of exercise training.
