Insulin level of resistance rises dramatically from age 9 to 13 years, then falls to the same extent until age 16. Our study found that exercise reduced this early-teenage peak in insulin resistance but experienced no influence at age 16, research author Brad Metcalf, a senior lecturer in physical health insurance and activity at the University of Exeter in England, said in a university news release. A decrease in this peak could lessen the demand on the cells that produce insulin during this critical period, which might protect them for longer in later life, Metcalf said.
