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 prevalent (p ≤ 0.05) during the total period after RE40%1RM (20.8 ± 21.2%) when compared with 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 vs. 4:00 ± 0:00, 3:40 ± 0:53, and 3:25 ± 1:09 hours, respectively), lunch (1:25 ± 2:03 vs. 4:55 ± 0:17, 4:25 ± 1:26, and 3:40 ± 2:06 hours, respectively), and dinner (0:15 ± 0:27 vs. 3:15 ± 0:45, 3:25 ± 0:47, and 2:50 ± 1:31 hours, respectively). During the sleeping period, there was a lower hyperglycemic state (p ≤ 0.05) in RE40%1RM (0:20 ± 0:39 hours) vs. RE80%1RM (4:05 ± 3:08 hours). 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 women with T2D.

Melo, KCB, Araújo, FdS, Cordeiro Júnior, CCM, de Andrade, KTP, and Moreira, SR. Pilates method training: Functional and blood glucose responses of older women with type 2 diabetes. J Strength Cond Res XX(X): 000-000, 2018-The objective of the study was to investigate the effects of 12 weeks (wk) of Pilates method on the functional capacity (FC) and glycemic control of older women with type 2 diabetes (T2D). Twenty-two women with T2D were randomized into the control (CONTROL: 67.5 ± 6.3 years; 154.7 ± 6.1 cm; 73.5 ± 6.1 kg) and Pilates groups (PILATES: 65.5 ± 5.5 years; 155.0 ± 4.5 cm; 66.2 ± 5.4 kg), which held sessions of 60 minutes 3× per week during 12 weeks. Blood glucose was measured before and after sessions in PILATES, as well as in moments of pre, rest, 4 weeks, 8 weeks, and 12 weeks of the PILATES and CONTROL interventions. The glycated hemoglobin (HbA1c) before and after 12 weeks of intervention was evaluated. The general index of FC (GIFC) was obtained through battery of tests for the older. Analysis of variance detected differences in GIFC for PILATES vs. CONTROL, respectively, in the 4 weeks (30.3 ± 4.6 seconds vs. 34.8 ± 4.9 seconds; p < 0.05), 8 weeks (29.2 ± 4.5 seconds vs. 34.6 ± 4.9 seconds; p < 0.05), and 12 weeks (27.2 ± 4.0 seconds vs. 35.3 ± 4.6 seconds; p < 0.05). PILATES presented difference in postprandial glycemia pre vs. 4 weeks and 12 weeks (246.1 ± 58.5 mg·dl vs. 219.9 ± 59.9 mg·dl and 207.6 ± 49.1 mg·dl, respectively; p < 0.05), as well as in the HbA1c pre vs. 12 weeks (7.8 ± 1.0% vs. 6.7 ± 0.6%, respectively; p < 0.05). Differences in postprandial glycemia (p < 0.05) were found in the PILATES before vs. after session, respectively, of the 1st-12th (217.1 ± 49.1 mg·dl vs. 157.9 ± 55.7 mg·dl), 13th-24th (204.5 ± 44.7 mg·dl vs. 146.3 ± 44.5 mg·dl), and 25th-36th (214.3 ± 40.4 mg·dl vs. 152.7 ± 52.0 mg·dl). Correlation between postprandial glycemia and GIFC after 12 weeks was detected (r = 0.37; p = 0.04). It is concluded that 12 weeks of PILATES method induce improvement and relationship in the FC and glycemic control in older women with T2D.

O objetivo primário do estudo foi analisar as respostas de glicose (GLIC) e secundariamente o comportamento da percepção subjetiva de esforço (PSE) e domínio afetivo durante exercício resistido (ER) de diferentes intensidades em mulheres com diabetes mellitus tipo 2 (DM2). Oito mulheres com DM2 foram submetidas a sessões randomizadas, sendo: a) Dia 1 – Controle (CON40 ou CON80) e b) Dia 2 – ER (ER40 ou ER80), realizado em três circuitos de sete exercícios cada, durante um período de 40 minutos. Foram avaliados: GLIC, PSE, feeling scale (FS) e Felt Arousal Scale (FAS). A GLIC reduziu significativamente para ER40 (140,0 ± 19,1 mg.dL-1) quando comparado ao repouso (228,3 ± 16,6 mg.dL-1), CON40 (241,3 ± 53,2 mg.dL-1), CON80 (220,9 ± 67,9 mg.dL-1) e ER80 (212,2 ± 70,9 mg.dL-1) na média geral da sessão (P<0,001) e a cada 5 minutos (P<0,001). Para FS e FAS não ocorreu efeito principal do tempo e nem diferenças entre sessões (P>0,05). Diferença significativa ocorreu na PSE entre sessões (ER40: 11,4 ± 1,2 pts vs. ER80: 12,9 ± 1,5 pts; P<0,05). A sessão ER40 promoveu maior redução da GLIC e, apesar de diferir na PSE, ambas intensidades de ER mantiveram os resultados de FS e FAS.
