Abstract

Moderate intense physical activity reduces the risk of Type 2 Diabetes Mellitus (Lynch & Helmrich, 1996) This paper reports on the effect of the time of the day of exercise on the blood glucose levels of Type 2 diabetic patients. Data were obtained from 30 Type 2 diabetics that exercised at the Centre for Diabetes and Endocrinology (Johannesburg, South Africa) under the supervision of Biokineticists (exercise scientists) for a 10 day period. The results of three groups who exercised (respectively) in the mornings, afternoons and evenings were compared. The group which exercised in the evening showed the best improvement in blood glucose levels. Their blood glucose level decreased with an average of 1.4 mmol/L over a 10 day period exercise program. Those exercising in the afternoon and morning had a decrease in blood glucose levels of 1.3 mmol/L and 0.6 mmol/L respectively. Looking at the changes that occured during exercise, the morning group showed a decrease of 3.3 mmol/L in blood glucose level. Corresponding decreases of the afternoon and evening group were 1.9 and 1.5 mmol/L. Apart from supporting the theory of Lynch & Helmrich (1996), this study strongly shows that the time of the day of exercise do have an effect on the blood glucose levels of Type 2 diabetes! To conclude the study, recommendations for further research in this regard are made.
