This study was conducted to determine if 15 minutes of postprandial light walking has an effect on the glycemic response to a Boost® beverage in individuals with type 1 diabetes. Seven participants, 22.3 + 4.3 yrs, with type 1 diabetes completed the two days of data collection. On day 1, participants measured baseline fasting blood glucose (BG) with a glucometer, consumed a Boost® beverage, and sat quietly, repeating BG measurements 15, 30, 60, 90, and 120 minute. On day 2, participants repeated the protocol, but walked 15 minutes at a light pace (50-60% max HR) immediately after beverage consumption. The difference between peak and baseline BG was significantly lower on the walking day compared to the sedentary day (6.4 + 1.2 vs 4.0 + 2.4, respectively, P < .05) as was the iAUC (468.6 + 94.5 mmol/L/120min vs 241.1 + 155.8 mmol/L/120min, P < .05). In conclusion, light walking for 15 minutes postprandially can blunt the spike in BG and overall glycemic response to a breakfast beverage in young adults with type 1 diabetes.
