Introduction:Type 2 diabetes mellitus (T2DM) currently accounts for majority of the world-wide burden of non-communicable diseases. The incidence and prevalence of diabetes is increasing world-wide, especially in the low and middle income countries, with an estimate that by 2030, approximately 366 million people in the world will have diabetes. In spite of plethora of anti-diabetic medications available for the treatment of T2DM, exercise and dietary modifications are, and will always remain the key advice in the management of T2DM, because it is effective at all stages of the disease, reduces HbA1c by approximately 0.51–0.89%, and is cost effective. Materials and Methods:The randomised crossover study was conducted among 100 type-2 diabetic subjects attending diabetic clinic organized by Department of Medicine. Type-2 diabetic people with coexisting hypertension, fasting blood glucose levels greater than 180 mg/dL and unable or unwilling to comply with required physical activity were not included. The subjects were randomly assigned to one of the two groups, Group I and Group II. Group I - A 30-minute morning walk each day. Group II - A 10-minute walk following each main meal. Each intervention lasted 15 days followed by a 30-day break. The participants then crossed over to the other group, they had not yet received. The fasting blood glucose levels were tested using glucose meter on day 1, day 7 and day 15 in both groups. Results:In this study, the participants act as their own controls and effect seen is mainly due to walking rather than the influence of other factors like dietary and physical activities. There is decrease in fasting blood glucose levels on day 7 and day 15, when compared to day 1 fasting blood glucose levels in both groups. The study found that when participants walked after meals, the level of fasting blood glucose was 10% to 12% lower than in those who went for a single walk each day. The results were analysed statistically by using t-test. Fasting blood glucose levels were decreased significantly after 10-minute post-meal walking in both groups (p-value <0.001) when compared to single 30-minute morning walk. Conclusion:This study can help the current physical activity guidelines to specify post-meal activity particularly when meals contain much carbohydrate in type-2 diabetic subjects. The findings of this small study can help to an inexpensive prevention strategy for prediabetes, which can develop overtime into type-2 diabetes. We can’t be sure if the benefits of a post meal walk are long-term because of the short duration of the study. From this study, 10-minute walk after a meal can significantly lower the blood glucose levels, thus emphasizing that simple lifestyle changes would benefit people with diabetes.
