High-volume endurance exercise (END) improves glycemic 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 10x60s cycling efforts at 90% maximal heart rate, interspersed with 60s 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 hyperglycemia measured as proportion of time spent above 10mmol/L (HIT: 4.5±4.4 vs. CTL: 15.2±12.3 %, p=0.04). Postprandial hyperglycemia, 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•9h, p=0.01). These findings highlight the potential for HIT to improve glycemic control in T2D. |
