A single session of high-intensity interval training reduced the proportion of time spent in hyperglycaemia compared to a non-exercise control day (4.5% vs. 15.2%, p=0.04) in adults with T2D.
Does acute high-intensity interval training reduce the postprandial glucose response and prevalence of hyperglycaemia in adults with type 2 diabetes?
A single session of high-intensity interval training significantly improves 24-hour glycemic control and reduces postprandial hyperglycemia in adults with type 2 diabetes.

High-volume endurance exercise (END) improves glycaemic control in type 2 diabetes (T2D) but many individuals cite 'lack of time' as a barrier to regular participation. High-intensity interval training (HIT) is a time-efficient method to induce physiological adaptations similar to END, but little is known regarding the effect of HIT in T2D. Using continuous glucose monitoring (CGM), we examined the 24-h blood glucose response to one session of HIT consisting of 10 × 60 s cycling efforts at ~90% maximal heart rate, interspersed with 60 s rest. Seven adults with T2D underwent CGM for 24-h on two occasions under standard dietary conditions: following acute HIT and on a non-exercise control day (CTL). HIT reduced hyperglycaemia measured as proportion of time spent above 10 mmol/l (HIT: 4.5 ± 4.4 vs. CTL: 15.2 ± 12.3%, p = 0.04). Postprandial hyperglycaemia, measured as the sum of post-meal areas under the glucose curve, was also lower after HIT vs. CTL (728 ± 331 vs. 1142 ± 556 mmol/l·9 h, p = 0.01). These findings highlight the potential for HIT to improve glycaemic control in T2D.
Gillen et al. (Mon,) conducted a other in type 2 diabetes (n=7). High-intensity interval training (HIT) vs. non-exercise control day (CTL) was evaluated on proportion of time spent above 10 mmol/l (p=0.04). A single session of high-intensity interval training reduced the proportion of time spent in hyperglycaemia compared to a non-exercise control day (4.5% vs. 15.2%, p=0.04) in adults with T2D.
