“…Our study is the first controlled study in patients with type 2 diabetes mellitus to examine the effects of post-meal activity on postprandial glycaemia in free-living individuals, and the first to have continued over a period longer than 2 days. Several previous studies have shown reduced postprandial glycaemia when a meal has been followed by physical activity compared with remaining sedentary [17][18][19][20][27][28][29][30]. These studies have typically included eight to 12 participants observed in a controlled setting with meals provided.…”

“…We hypothesized that a single bout of walking after breakfast would lower postprandial glucose after that one meal but activity breaks after each meal would lower postprandial glycemia throughout the day. Second, although it is well established that continuous and intermittent physical activity lowers glucose concentrations in people with type 2 diabetes (3,5,21,27,31,32,34,36), the relationship between the dose of activity and magnitude of change to glycemia is less clear. To better understand that dose-response relationship, we compared three volumes (doses) of activity that span the physical activity recommendations (20, 40, and 60 min).…”

Breaking up sitting with light physical activity (PA) is effective in reducing hyperglycemia in the laboratory. Whether the same effects are observed in the free-living environment remains unknown. We evaluated how daily and postprandial glycemia is impacted by 20, 40, or 60 min of activity performed as either breaks from sitting after each meal (BR) or as one continuous walk after breakfast (WALK). Thirty individuals with type 2 diabetes completed three experimental conditions [BR, WALK, and control (CON)] in a randomized crossover design. Conditions were performed in a free-living environment with strict dietary control over 7 days. Participants increased PA in BR and WALK by 20, 40, or 60 min ( n = 10 in each group) and maintained habitual levels of PA during CON. A continuous glucose monitor (iPro2) and activPAL activity monitor were worn to quantify glycemic control and PA. Using linear mixed models with repeated measures, we 1) compared postprandial glucose (PPG) across conditions and 2) assessed the relationship between activity volume and glucose responses. Whereas WALK tended to shorten the daily duration of hyperglycemia compared with CON ( P = 0.0875), BR was not different from CON. BR and WALK significantly attenuated the breakfast PPG versus CON ( P ≤ 0.05), but lunch and dinner PPG were unaffected by BR and WALK. In conclusion, continuous walking was more effective than breaks from sitting in lowering daily hyperglycemia for the group, but both conditions lowered breakfast PPG. In contrast to tightly controlled laboratory studies, breaks from sitting did not lower hyperglycemia in the free-living environment. NEW & NOTEWORTHY Our “ecolabical” approach is new and noteworthy. This approach combines the external validity of the free-living environment (ecological) with the control of key confounding variables in the laboratory and allows for highly translatable findings by minimizing confounding variables. We found that both postmeal continuous walking and short breaks from sitting similarly attenuated the postprandial glucose (PPG) response to breakfast. Unlike previous laboratory studies, neither condition (walk after breakfast or postmeal breaks) significantly impacted PPG at lunch or dinner.

“…Entretanto, o design randomizado cruzado do presente estudo minimiza essa limitação, em conjunto ainda aos procedimentos de ingestão alimentar, exercício físico e tempo os quais foram padronizados em todas as sessões realizadas. Em adicional, outros trabalhos 39,40 associados aos resultados do presente estudo, suportam a segurança fi siológica da metodologia empregada, no tocante a não ocorrência de possíveis eventos hipoglicemiantes durante e após a realização do exercício físico.…”

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.
