The aim of this study is to evaluate whether there is a change in carotid intima media thickness with the application of guide-based exercise programs in individuals with prediabetes, and to evaluate whether there is a difference between the group in which exercise programs were applied and those who received only lifestyle change and metformin.

The researchers think that the application of guide-based exercise programs in prediabetes patients will decrease the carotid intima-media thickness.The aim of this study is to evaluate whether there is a change in carotid intima media thickness with the application of guide-based exercise programs in individuals with prediabetes, and to evaluate whether there is a difference between the group in which exercise programs were applied and those who received only lifestyle change and metformin.
