Subjects with type 2 diabetes completed a cross-over study where they underwent three 1-hour interventions in a counterbalanced order: 1) Interval walking consisting of repeated cycles of 3 min slow and 3 min fast walking (IW3); 2) Interval walking consisting of repeated cycles of 1 min slow and 1 min fast walking (IW1) and 3) No walking (CON). Oxygen consumption and heart rate were measured throughout the interventions.
