Predictors of Exercise Performance in Type 1 Diabetes: The Role of Hypoglycaemia Fear, Glycaemic Control, and Vascular Health: A Retrospective Cross‐Sectional Study
Authors' conclusion
Fear of hypoglycaemia, HbA1c and microvascular complications are key determinants of reduced cardiopulmonary exercise performance in type 1 diabetes, highlighting the need for integrated physiological and psychological interventions.
Study context
- Population
- Adults with T1D in a multidisciplinary rehabilitation program at the University Medical Centre Groningen; median age 33 years, 76 females; median HbA1c 75 mmol/mol (IQR 63–93)
- Participants
- 122 adults
- Outcome
- Oxygen uptake, power output and heart rate at ventilatory thresholds and peak exercise
Methodological detailssingle-centre
- Single-centre
