Effects of Postprandial Walking and Resistance Snacking on Glucose Responses in Adults With Metabolic Syndrome

NCT07620886 · Status: NOT_YET_RECRUITING · Phase: NA · Type: INTERVENTIONAL · Enrollment: 25

Summary

This study will examine whether light physical activity after meals can improve 24-hour glucose responses in adults with metabolic syndrome and prediabetes.

Participants will complete three experimental conditions in a randomized crossover order: prolonged sitting, 15 minutes of postprandial walking, and brief resistance exercise snacks consisting of squats and calf raises performed every 20 minutes during the postprandial period. Continuous glucose monitoring will be used to assess 24-hour glucose responses, and heart rate variability will be measured during the 2-hour postprandial period to evaluate acute autonomic responses.

The main outcome is 24-hour mean glucose derived from continuous glucose monitoring.

Conditions

Interventions

BEHAVIORAL

Postprandial walking

Participants will perform 15 minutes of light-to-moderate walking after consuming a standardized meal. Walking intensity will be monitored using heart rate and rating of perceived exertion.

BEHAVIORAL

Brief resistance exercise snacks

Participants will perform 3-minute bouts of body-weight resistance exercises every 20 minutes during the postprandial period after consuming a standardized meal. The exercise bouts will include squats and calf raises.
