ABSTRACT
INTRODUCTION: The study investigated the effect of 12 weeks of pilates training on the hemodynamic responses of older women with type-2 diabetes (T2D). METHODS: 22 individuals with T2D were randomly allocated into two groups: CONTROL (n = 11; 67.5 ± 6.3 years; 154.7 ± 6.1 cm; 73.5 ± 6.1 kg; calorie intake: 1487.5 ± 360.6 kcal/day) and PILATES (n = 11; 65.5 ± 5.5 years; 155.0 ± 4.5 cm; 66.2 ± 5.4 kg; calorie intake: 1289.3 ± 385.0 kcal/day). The PILATES group executed a 12-week PILATES training program at moderate intensity, 3x/week with each session lasting 60-min. Systolic blood pressure (SBP), diastolic blood pressure (DBP), heart rate (HR), and postprandial blood glucose were assessed at four timepoints: i) baseline; ii) 4th week; iii) 8th week; and iv) 12th week (s) of intervention. Two-way ANOVA for repeated measures and the Pearson's correlation coefficient were adopted. The alpha level was set at 0.05. RESULTS: A time∗group interaction effect was found for SBP (F = 4.206; η2 = 0.17; p = 0.02) and DBP (F = 2.624; η2 = 0.12; p = 0.05) with significant reductions (mmHg) in the 4ths and 8ths in the PILATES (PILATES SBP baseline: 134.9 ± 27.6; 4ths: 112.4 ± 15.7; 8ths: 115.8 ± 18.3; 12ths: 124.3 ± 19.1 vs. CONTROL SBP baseline: 126.5 ± 15.7; 4ths: 126.3 ± 16.2; 8ths: 124.5 ± 13.1; 12ths: 126.3 ± 21.4 | PILATES DBP baseline: 72.9 ± 11.3; 4ths: 65.1 ± 12.2; 8ths: 65.8 ± 12.2; 12ths: 67.6 ± 7.5 vs. CONTROL DBP baseline: 74.6 ± 12.0; 4ths: 73.9 ± 11.5; 8ths: 75.3 ± 11.9; 12ths: 74.5 ± 9.2). CONCLUSION: Four and eight weeks of PILATES training promotes reduction in the SBP and DBP of older women with T2D. The exercises performed in this study were mainly body weight exercises and required a few auxiliary materials, which turns this method of training accessible.

O exercício resistido (ER) pode reduzir a glicose no sangue em pessoas com diabetes tipo 2 (DM2). No entanto, é necessária maior clareza quanto à intensidade do ER e ao tempo necessário para essa resposta aguda. Portanto, o objetivo deste estudo foi comparar as respostas agudas de glicose no sangue no segundo dia de recuperação do ER moderada versus de alta intensidade em mulheres com DM2. Doze mulheres com DM2 (55,2 ± 4,0 anos; 70,1 ± 11,4 kg; e 155,7 ± 3,3 cm) realizaram duas sessões experimentais com sete dias de intervalo em ordem aleatória. Para a sessão 1: ER40% do teste de uma repetição máxima (1RM) e sessão 2: ER80%1RM, com 16 e 8 repetições para cada série, respectivamente, em 7 exercícios com 3 circuitos durante 40min. A glicemia foi monitorada por 35h (primeiro dia: 24h e segundo dia: 11h) a cada 5 minutos após cada sessão experimental pelo Sistema de Monitoramento Contínuo de Glicose (modelo Guardian REAL-Time). O teste t de Student não mostrou diferença significativa na glicemia do segundo dia (11h) após as sessões de ER40%1RM vs. RE80%1RM [respectivamente, 161,3 ± 62,3 mg.dL-1 vs. 157,2 ± 41,9 mg.dL-1; t (11) = 0,259; p = 0,800]. A ANOVA two-way para medidas repetidas mostrou que as respostas de glicose no sangue a cada hora durante a recuperação no segundo dia não mostraram diferenças significativas entre as sessões de ER [F (1,731; 19,039) = 0,688; p = 0,734]. Concluímos que as respostas glicêmicas agudas no segundo dia da recuperação do ER de intensidade moderada e alta não diferiram entre as mulheres com DM2.
Resistance exercise (RE) can lower blood glucose in people with type 2 diabetes (T2D). However, greater clarity is needed regarding the RE intensity and time required for this acute response. Therefore, the aim of this study was to compare acute blood glucose responses on the second day of recovery from moderate vs. high-intensity RE in women with T2D. Twelve women with T2D (55.2 ± 4.0 years; 70.1 ± 11.4 kg; and 155.7 ± 3.3 cm) performed two experimental sessions seven days apart in a randomized order. For session 1: RE40% of one-repetition maximum test (1RM) and session 2: RE80%1RM, with 16 and 8 repetitions for each set, respectively, in 7 exercises with 3 circuits during 40min. Blood glucose was monitored for over 35h (first day: 24h and second day: 11h) every 5 minutes after each experimental session by the Continuous Glucose Monitoring System (Guardian REAL-Time model). Student's t-test showed no significant difference in blood glucose on the second day (11h) after RE40%1RM vs. RE80%1RM sessions [respectively, 161.3 ± 62.3 mg.dL-1 vs. 157.2 ± 41.9 mg.dL-1; t (11) = 0.259; p = 0.800]. Two-way ANOVA for repeated measures showed that blood glucose responses every hour during recovery on the second day showed no significant differences between RE sessions [F (1.731, 19.039) = 0.688; p = 0.734]. We concluded that the acute blood glucose responses on the second day of moderate and high intensity RE did not differ among women with T2D.
