This study aimed to provide foundational data for developing exercise strategies to mitigate postprandial blood glucose spikes by comparing the effects of different intensities of circuit weight training on heart rate, exercise volume, and blood glucose responses in healthy men in their 20s. Ten participants completed three conditions in a randomized crossover design: non-exercise, hypertrophy-oriented (70–80% 1RM), and muscular endurance-oriented (50–60% 1RM) circuit training. Each session included eight resistance exercises over two circuit cycles with differing rest intervals. Repeated-measures two-way ANOVA and paired t-tests were used for analysis. No significant heart rate difference was found between exercise intensities, though heart rate increased in the second cycle across both. Total exercise volume was significantly higher in the muscular endurance condition. Blood glucose peaked 20 minutes post-meal and declined, followed by a rebound postexercise. At 40 and 60 minutes postprandially, both exercise groups showed significantly lower glucose levels than the non-exercise group, with no difference between the two training intensities. These results suggest that exercise volume and rest intervals may impact postprandial glucose more than intensity alone.
