It is well accepted that walking can improve diabetic control and support weight loss…which also improves insulin sensitivity and diabetic control. A recent study published in the electronic format of Diabetologia found that walking at alternating levels of intensity improves insulin sensitivity in type II diabetes. This was found to be better than walking at a constant pace whilst expending the same amount of energy. Consequently, new exercise prescriptions may favour exercising at various intensities rather than a constant training volume and constant intensity. The utilisation of glucose (aka glucose disposal) appears to be better when walking intensity is varied, and the researchers believe that high training volume alone is not enough to induce metabolic shifts to the extent of intermittent intensity walking. The researchers believe that the improved blood sugar control seen in diabetics who perform varied intensity walking is in part due to the increased sensitivity (49.8% increase in the insulin- sensitivity index, P value <0.001), and increased peripheral glucose disposal (by 14.5% P value <0.05). So interval training may well be the way forward in diabetic control, but diabetes is very subjective with everybody responding differently. Consequently, when embarking on a training regime with diabetes be sure to consult your Doctor or Diabetic Nurse prior to commencing.
