The Acute Effect of Moderate Intensity Stair-Climbing on Postprandial Blood Glucose

The Acute Effect of Moderate Intensity Stair-Climbing on Postprandial Blood Glucose

This study aims to investigate the effect of moderate intensity stair-climbing bouts of various durations on postprandial blood glucose. Participants will perform a standard oral glucose tolerance test (OGTT) using 75g of dextrose and with fingerstick blood glucose measurements at baseline and every 15 minutes after consuming the drink for one hour. On separate subsequent visits, participants will perform the same OGTT combined with three stair-climbing bouts lasting 1, 3, and 10 minutes starting 27, 25, and 18 minutes respectively after finishing the drink. Participants performed maximal aerobic capacity (VO2max) using a ramp treadmill test in order to assess the relative intensity of each stairclimbing trial.
