Exercise Trial

In the exercise trial, participants consumed the standard meal described above and then waited for 15 minutes, during which time they sat quietly. Following this time period, participants completed a 15-minute session of treadmill walking at a self-selected pace. No instruction was given to participants regarding their walking pace or intensity. Although exercise was based on self-selected pace, intensity was monitored via heart rate and RPE. Intensity of exercise would be based upon subject’s age predicted max HR using the equation 208-(.7*age) with moderate intensity exercise occurring at 64-75 percent of maximum HR according to the American College of Sports Medicine (1).
Each three minutes throughout the exercise session participants were asked to provide their rating of perceived exertion (Borg 6-20 scale) by verbally indicating their rating shown on the chart provided. Heart rate and blood pressure were recorded every five minutes during the exercise session. Blood glucose readings were taken at baseline (pre-meal) and at 30, 60, 90, and 120 minutes.
