A short bout of stair climbing-descending exercise attenuates postprandial hyperglycemia in middle-aged males with impaired glucose tolerance.

Exercise is a useful modality to ameliorate postprandial hyperglycemia. Here we show that a short bout (∼6 min) of stair climbing-descending exercise (STAIR) starting at 90 min after meal accelerates the decrease in blood glucose concentrations in middle-aged sedentary men with impaired glucose tolerance, although STAIR is easy to perform and keeps the exercise intensity at a moderate level.
