The Study
A single session of resistance exercise enhances insulin sensitivity for at least 24 h in healthy men
This study saw that after one workout, healthy young men's bodies handled sugar a bit better the next day. But it didn't randomly assign who worked out and who didn't, so we can't be sure the workout caused the improvement — it might just be something else happening at the same time.
Analysis score
Maximum 90 for a randomized controlled trial.
Where the score came from
When you lift weights, your muscles get better at soaking up sugar from your blood—even the next day.

Key takeaways
Summary
Based on the study abstract and findings.
- 1Yes—this means your body handles sugar more efficiently after exercise, which helps prevent spikes and could lower diabetes risk over time.
- 2After one workout (8 sets of 10 leg lifts at 75% max effort), sugar control improved by 13% ± 5% for 24 hours.

People who engage in regular physical exercise maintain stable insulin sensitivity across the entire day, regardless of when they eat meals.
One session of leg resistance training at 75% of maximum strength increases how effectively the body clears glucose from the blood by 13% in healthy young men, and this effect lasts at least 24 hours without altering baseline glucose or insulin levels.
