Abstract: Prior studies have investigated the efficacy of a single 1 min bout of stair‐stepping on reducing postprandial blood glucose (BG) in the morning, but none have investigated this effect in the evening when glycaemic responses are larger due to circadian regulation and β‐cell responsiveness. This work investigated the efficacy of a 1 min bout of self‐selected, low‐intensity stair‐stepping performed in the evening on reducing the change from baseline to the 60 min time point postprandial BG. Thirty people (43% male, 29 (10) years) participated in a randomized crossover‐controlled trial. Participants completed two separate evening trials following an oral glucose tolerance test (OGTT) (75 g of dextrose dissolved in water): (a) 0 min of stair‐stepping seated control condition, and (b) 1 min of stair‐stepping condition. One minute of stair‐stepping attenuated the change from baseline to 60 min postprandial BG versus control condition (2.5 (2.8) vs. 4.3 (2.3) mmol/L ( P < 0.001). Area under the curve (AUC) and incremental area under the curve (iAUC) were lower for the 1 min condition versus control (mean difference = −0.4,95% CI: 0.1–0.8 ( P = 0.023) and (mean difference = −0.6, 95% CI 0.1–1.1 mmol/L −1 min −1 ( P = 0.043), respectively. The modified BORG rate of perceived exertion scale showed participants perceived the exercise as light intensity (1.9 (1.1)). A single, 1 min bout of low‐intensity stair stepping at a self‐selected pace reduced evening postprandial BG levels following an OGTT in young non‐diabetic adults.
