Vary Walk Speed to Boost Insulin Sensitivity
Walking to help control your type 2 diabetes? Try varying your speed every few minutes, from fast to slow and back again. In a four-month study, 32 adults with type 2 diabetes (who were not using insulin) walked for an hour a day, five days a week. Body weight dropped by about 9 pounds and average blood glucose levels decreased from 162 mg/dl to 157 mg/dl among those who were instructed to vary their speed every three minutes, but the continuous-speed group saw no such health improvements. The difference was due to better insulin sensitivity with variable-speed walking, researchers say.
