Elite Cyclists with Type 1 Diabetes Show Acceptable Glycemic Excursions During a Time-Trial Performance Under High-Definition Transcranial Direct Current Stimulation
Authors' conclusion
Because glycemic control is crucial for both health and performance, these findings suggest that HD-tDCS could be safely used to enhance performance in athletes with T1D and potentially in a broader active T1D population.
Study context
- Population
- Elite cyclists with T1D (no complications), constant-load trial at 75% of second ventilatory threshold plus 15-km cycling time trialcrossover
- Participants
- 9 participants
- Comparison
- Bilateral DLPFC high-definition transcranial direct current stimulation (HD-tDCS) vs SHAM
- Primary endpoint
- Glycemic excursions (glycemic variability on real-time CGM) during time-trial performance
Methodological detailsdouble-blind
- Double-blind
Primary result
As reported in the abstract
Glycemic variability (real-time CGM)
- Similar glycemic variability between the 2 conditions; significant effect of time but no interaction (stimulation × time) or stimulation effect
