Summary
This study looks at whether exercising in the morning or evening helps the body handle sugar better in people with prediabetes who have an extreme natural body clock. Twenty-eight adults with prediabetes and overweight will do a single cycling session at 9 AM, 5 PM, or no exercise on separate days. Researchers will measure how well insulin works after each session to see if timing matters.
