Abstract

The study herein aimed to compare glucose concentration and hyperglycemic responses of 24-hours after resistance exercise (RE) performed in different intensities in patients with type-2 diabetes (T2D). Twelve women with T2D (55.2±4.0 years; 70.1±11.4 kg; 155.7±3.3 cm) performed four experimental sessions divided into two blocks separated by 7 days and in randomized order: block-A (session-1: control-CONT40% and session-2: RE40% of one repetition maximum test-1RM) and block-B (session-3: CONT80% and session-4: RE80%1RM). The RE sessions were performed over 40min with three circuits of seven exercises each, with 40%1RM and 80%1RM with 16 and 8 repetitions for each set, respectively. Glucose was monitored over 24-hours after each experimental session through continuous glucose monitoring system. One-way ANOVA for repeated measures showed that AUC-glucose was reduced (p<0.05) after RE40%1RM (193.738±33.186 mg.dL x 1.380 min) when compared to CONT40% (263.937±26.665 mg.dL x 1.380 min), CONT80% (254.721±35.836 mg.dL × 1.380 min), and RE80%1RM (263.966±62.795 mg.dL × 1.380 min). Hyperglycemia (>160 mg.dL) was less prevalent (p<0.05) during the total period after RE40%1RM (20.8±21.2%) when compared to CONT40% (77.4±18.3%), CONT80% (69.4±24.6%), and RE80%1RM (66.0±33.7%). There was a lower hyperglycemic state in RE40%1RM (p<0.05) vs. CONT40%, CONT80%, and RE80%1RM after breakfast (1:25±0:54 h vs. 4:00±0:00 h, 3:40±0:53 h and 3:25±1:09 h, respectively), lunch (1:25±2:03 h vs. 4:55±0:17 h, 4:25±1:26 h and 3:40±2:06 h, respectively) and dinner (0:15±0:27 h vs. 3:15±0:45 h, 3:25±0:47 h and 2:50±1:31 h, respectively). During the sleeping period, there was a lower hyperglycemic state (p<0.05) in RE40%1RM (0:20±0:39 h) vs. RE80%1RM (4:05±3:08 h). A single low intensity RE40%1RM decreases hyperglycemic prevalence over a 24-hour period and ameliorates glucose control after meals and in sleeping periods in T2D women.
