Abstract (summary)

The purpose of this investigation was to compare the effect of acute low- and high-intensity resistance exercise of equal work output on glucose uptake in resistance-trained males. The methods included the fifteen healthy male (22.95 ± 3.82 yrs), resistance-trained (6.73 ± 3.93 yrs) subjects, who completed three treatment sessions: CON-(no-exercise control), HI (3 x 8, 85% 10-RM), and LO (3 x 15, 45% 10-RM). The HI and LO exercise treatment sessions consisted of eight resistance exercises, with equated total workloads. Glucose uptake was measured the following morning by hyperinsulinemic euglycemic clamp technique. Glucose disposal was measured by analyzing the glucose infusion rate during the final 30 minutes of steady-state blood glucose concentrations. Insulin sensitivity was calculated by dividing the glucose infusion rate by the average insulin infusion. The results indicate that fasting blood glucose levels did not change among treatment sessions (CON = 80.49 ± 5.29 vs. HI = 77.05 ± 4.91 vs. LO = 77.12 ± 5.96 mg/Dl). Glucose uptake was not significantly different among treatment sessions (CON = 11.31 ± 3.02 vs. HI = 11.67 ± 2.68 vs. LO = 11.42 ± 2.77 mg/kgFFM/min). Insulin sensitivity did not change among treatment sessions (CON = 0.26 ± 0.09 vs. HI = 0.280 ± 0.07 vs. LO = 0.27 ± 0.06 (mg/kgFFM/min)/(uU/ml)). In conclusion, these data indicate that for acute resistance exercise bouts with an equated work volume, low- and high-intensity sessions have similar effects on glucose uptake, but are no different than a no-exercise control session in resistance-trained men. The trained status of the sample may have produced maximum exercise-induced cellular adaptations for enhanced insulin sensitivity and glucose uptake prior to the acute testing session.
