Diabetes study reveals hidden impact on exercise performance

NCT ID NCT02051504

First seen May 15, 2026 · Last updated May 15, 2026

Summary

This study looked at how type 1 diabetes and long-term blood sugar control (HbA1c) affect the body's ability to deliver and use oxygen during exercise. Researchers compared 79 participants—some with type 1 diabetes and some healthy—to understand why people with diabetes often have lower aerobic fitness. The goal was to see if high blood sugar directly limits oxygen release to muscles and reduces exercise capacity.
