Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Exercise intervention to improve blood flow to skeletal muscle thereby decreasing insulin resistance and improving gycaemic control. Those randomised to the intervention will participate in a 12 week intensive exercise program 3 times per week (1 hour) consisting of a combination of aerobic and resistance exercises tailored to the patient. They will then be given a home exercise program tailored to them by an accredited exercise physiologist. The intensive exercise program will be repeated at the end of one year. Exercise sessions will be in small groups approximately 6-8 participants.
