New research published in Diabetologia (the journal of the European Association for the Study of Diabetes) suggests that training with alternating levels of walking intensity (interval training) could be better than walking at a constant speed to help manage blood sugar in people with type 2 diabetes. The research is by Dr Thomas Solomon, University of Copenhagen, Denmark, and colleagues.
The effects of exercise on blood sugar (glycaemic) control in individuals with type 2 diabetes are well documented but the optimal exercise intensity and type remains to be defined. Traditionally, high-intensity exercise has not been recommended for individuals with type 2 diabetes due to a fear of inducing injuries and discouraging patients from continuing with the exercise program. Nevertheless, high-intensity exercise improves glycaemic control more than low-intensity exercise.
