The current study examined the effects of accumulated short bouts of walking on glycosylated hemoglobin (HbA1c) and homeostasis model assessment of insulin resistance (HOMA-IR) of older adults with type 2 diabetes. Differences in variables between models of accumulated bouts of walking and 10,000 steps were also investigated. Sedentary participants ( = 38) were randomized into one of three groups: accumulated 10-minute bouts of walking at 100 steps/min (10/100MW), accumulated 10,000 steps (10KS), or control. HbA1c, HOMA-IR, blood lipids, and cardiorespiratory fitness (VO max) were assessed before and after the intervention. VO max, HbA1c, and HOMA-IR in the 10/100MW and 10KS groups showed significant and comparable improvements postintervention compared to preintervention ( < 0.05). Furthermore, the change in average daily step count was significantly associated with the change in HbA1c of the two walking groups ( = -0.61 for 10KS and = -0.63 for 10/100MW; < 0.05). Accumulated short bouts of walking at 100 steps/min and 10,000 steps daily improved HbA1c and HOMA-IR of older adults with type 2 diabetes. [ (x), xx-xx.].
