Low intensity resistance exercise reduces hyperglycemia and enhances glucose control over a 24-hour period in women with type 2 diabetes. J Strength Cond Res 33(10): 2826–2835, 2019—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; and 155.7 ± 3.3 cm) performed 4 experimental sessions divided into 2 blocks separated by 7 days and in randomized order: block-A (session-1: control-CONT40% and session-2: RE40% of one repetition maximum [1RM] test) and block-B (session-3: CONT80% and session-4: RE80%1RM). The RE sessions were performed over 40 minutes with 3 circuits of 7 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 area under the curve of glucose concentration was reduced (p ≤ 0.05) after RE40%1RM (193.738 ± 33.186 mg·dl−1 × 1.380 min−1) when compared with CONT40% (263.937 ± 26.665 mg·dl−1 × 1.380 min−1), CONT80% (254.721 ± 35.836 mg·dl−1 × 1.380 min−1), and RE80%1RM (263.966 ± 62.795 mg·dl−1 × 1.380 min−1). Hyperglycemia (>160 mg·dl−1) was less ...
