Continuous glucose monitoring for during exercise carbohydrate fuelling strategies🩸
Do they provide valuable information?
Comparative effects of continuous glucose monitoring-informed and traditional interval-based carbohydrate refueling protocols on endurance exercise responses: an exploratory study
Study Details
This new study recruited 12 healthy males to complete two 75-min bouts of endurance exercise with either…
🥤 Traditional carb refuelling (16g every 15-mins: 51 g/hr)
🩸 CGM-informed refuelling (individualised to avoid hypoglycaemia)
Here is what they found ⬇️
Key Findings
The average carb intake during the CGM condition was 18.1 ± 10.1 g/hr (65% lower than traditional) 📉
Despite the disparity in carb intake, no significant differences were observed between conditions for…
🫀 heart rate
🩸 blood lactate
🥵 perceived exertion
The CGM-informed protocol displayed lower variation of glucose levels (8.82 ± 4.68%) vs the traditional protocol (11.95 ± 3.41%) 📊
Conclusion
Personalised CGM-informed refuelling protocols may aid in stabilising glucose levels during steady-state endurance exercise ✅
However as of yet, evidence suggests this does not result in any physiological improvement or enhanced athletic performance ❌
