The aim of this study is to evaluate whether there is a change in GDF-15 levels in individuals with prediabetes at the 2nd hour after the first exercise and after a 12-week exercise program with guide-based exercise programs.

GDF-15, which has anorexigenic effects, increases with exercise. In prediabetic patients, GDF-15 is higher than healthy controls. The effect of exercise on GDF-15 levels in prediabetic patients is unknown.

The aim of this study is to evaluate whether there is a change in GDF-15 levels after the application of guideline-based exercise programs in individuals with prediabetes at the 2nd hour after the first exercise and after a 12-week exercise program.
