ABSTRACT
Descriptive study was carried out during the marathon of Yemeni diabetic patients as a public activity in the World Diabetes Day [WDD] to encourage the Yemeni people and educate them about the importance of physical activity, and to study the effect of walking as a mild physical activity on lowering blood sugar level. A total of 502 participants aged between 15 and 70 years, 85% males and 15% females, 352 diabetics; 8.32% type 1 and 26.29% type 2. Also 150 [29%] non diabetic participants [unknown] were included. All participants subjected to analysis of [RBS] at the beginning of marathon and at the end of it for most of them. After 4 km walking during 45 minutes we found that there was a significant reduction in R.B.S; it was 24.44 mg/dl, 15.80 mg/dl, and 27.19 mg/dl among all participants, type 1 and type 2 diabetic patients respectively. The significant reduction in R.B.S level after walking means that the beneficial effect of exercise can be obtained by mild to moderate exercise, since the effect seems to depend on overall energy expenditure rather than on intensity of exercise
