Abstract

OBJECTIVE:

We examined whether stair climbing-descending exercise (ST-EX), a convenient method to increase physical activity in daily life, for a short period would acutely improve the postprandial blood glucose (BG) response in people with type 2 diabetes (T2D).

METHODS:

16 people with T2D (age 65.4±1.1 years) participated in 2 separate sessions. After an overnight fast, each participant consumed a test meal and then kept resting for 180 min, except when performing each 3 min bout of ST-EX at 60 and 120 min after the meal (ST-EX session), or kept resting for 180 min (REST session). ST-EX comprised 6 continuous repetitions of climbing to the second floor (21 steps) at a rate of 80-110 steps/min followed by walking down slowly to the first floor at a free step rate.

RESULTS:

The BG at 60 min after the meal during the ST-EX session (immediately before the first ST-EX) did not differ from that during the REST session, but analysis of variance revealed a significant interaction between time and treatment (p<0.01). The BG at 150 min after the meal (30 min after the second ST-EX) was significantly lower than that during the REST session (p<0.01). The area under the curve was also 18% lower during the ST-EX session than during the REST session (p<0.05). The heart rate and blood lactate levels indicated that the actual intensity of ST-EX was 'hard'. In contrast, the rating of perceived exertion (RPE) indicated that the overall intensity of ST-EX was 'moderate' because of decreased RPE scores during descent.

CONCLUSIONS:

The present findings suggest that performing 3 min ST-EX 60 and 120 min after a meal may be a useful strategy to accelerate the decrease in postprandial BG levels in people with T2D.
