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.

|---|---|---|---|
| Bodyweight Exercise | Experimental | 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. |
|
| Non-Exercise Control | No Intervention | An 11-minute period of quiet sitting. |
| Name | Type | Description | Arm Group Labels | Other Names |
