The Effect of Brief Bodyweight Exercise on Acute Glycemic Control in Healthy Inactive Adults

This study will investigate whether an 11-minute bodyweight exercise session can improve short-term glycemic control. Glycemic control refers to the process of how the body regulates blood sugar. The process can be measured in different ways. This study will use a small device called a continuous glucose monitor to measure changes in glucose levels over a 24-hour period. Participants will complete two trials and the investigators will compare glycemic control after the exercise session and a control period that does not involve exercise. Food intake will be controlled such that each participant will consume the same diet in both conditions. This study will help determine whether a single session of bodyweight exercise affects glycemic control.

This study will investigate whether an 11-minute bodyweight exercise session can improve short-term glycemic control. Glycemic control will be assessed using continuous glucose monitoring for 24 hours following exercise or a control condition that does not involve exercise. The exercise and control periods will be directly supervised by a study investigator. Participants will complete two trials in a randomized, crossover manner separated by 7 days. Food intake will be controlled such that each participant will consume the same diet over the 24-hour period of measurement in both conditions. Standardized meals will be provided to participants prior and following the exercise and control conditions. This study will determine whether a single session of bodyweight exercise affects glycemic control as primarily assessed by mean 24-hour glucose.

A standardized 11-minute bodyweight exercise session that involves a 1-minute warm-up followed by 5, 1-minute bouts of exercise at a self-selected "challenging" pace, interspersed with 1-minute periods of low-intensity exercise for recovery.

Inclusion Criteria: Inactive, defined as not meeting the physical activity targets in the Canadian 24-Hour Movement Guidelines for Adults. Deemed able to safely participate in physical activity and exercise, as determined by the Canadian Society for Exercise Physiology (CSEP) Get Active Questionnaire prescreening tool. Exclusion Criteria: - Experiencing a condition that might preclude safe participation in physical activity and exercise, as determined by answering "Yes" to any question on Page 1 of the CSEP Get Active Questionnaire.
