 Type 2 diabetes T2D can be defined as a bihormonal metabolic disorder characterised by insufficient insulin secretion and abnormal glucagon secretion. It is however well established that physical activity per se improves glucose and may postpone or even slow down in the diabetic population. Glycaemic control may be improved more by high intensity interval training than by intensities from existing recommended guidelines. Additionally, there seems to be accumulating evidence that high intensity interval training induces increased overall fat and abdominal fat mass loss as opposed to traditional continuous endurance training Therefore we hypothesise that 3 weekly sessions of high intensity interval training 10×60 sec. at an intensity inducing 90 of maximal heart frequency with a recovery of 60 sec. between each bout over 8 weeks improves overall glycaemic control glucose, insulin and glucagon, inflammatory status interleukins, cytokines, chemokines and cell adhesion molecules and blood flow NO and PGI2 vasodilatory capabilities.
