Traditional steady state aerobic exercise training is a proven method to treat metabolic disorders, in particular diabetes. Short duration high intensity interval training (HIIT) induces similar metabolic adaptations and improvements. To date, most HIIT studies have utilized “all out” efforts; however, lower intensity HIIT has recently been demonstrated to produce similar effects to all out efforts in healthy adults. It is unknown whether a lower intensity HIIT has the capacity to improve insulin resistance in a diseased population. Nine untrained type 2 diabetics [age=40.2 ± 9.1 yr; BMI = 33.9 ± 5.31 kg/m 2 ; VO 2max = 1.95 ± .21 L/min (mean ± SD)] performed 6 training sessions of HIIT over 2 weeks. Anthropometric measures, homeostatic model assessment of insulin resistance (HOMA‐IR), fasting triglycerides, and cholesterol were unchanged with training (p<0.05); however, most measures trended towards improvement, especially among those with the highest HOMA‐IR values at the start of the intervention. Moreover, this short duration exercise was able to significantly reduce blood glucose after each interval bout (9.7±3.9mmol pre versus 8.3±3.4mmol post, p<0.05). These data provide novel information for future studies and give evidence that interval training programs longer than 2 weeks may be able to garner significant improvements in glucose control in a diabetic population.
