Summary
Children with type 1 diabetes exhibit reduced exercise capacity. Even with good metabolic control, diabetic adolescents show lower peak oxygen uptake and O2 pulse during exercise tests compared to healthy peers.
Area of Science:
- Pediatric Endocrinology
- Exercise Physiology
- Metabolic Disorders
Background:
- Type 1 diabetes mellitus (T1DM) affects children and adolescents, requiring careful management.
- Understanding the impact of T1DM on physical capacity is crucial for comprehensive care.
Purpose of the Study:
- To assess the cardiorespiratory and metabolic responses to exercise in children with T1DM.
- To compare exercise performance in T1DM adolescents with age- and sex-matched healthy controls.
Main Methods:
- Evaluated 33 children with T1DM (aged 9-15) on insulin therapy and 47 healthy controls.
- Conducted pulmonary function tests and progressive treadmill exercise tests.
- Monitored gas exchange, ventilation, heart rate, and calculated O2 pulse.
Main Results:
- Diabetic adolescents had significantly lower peak oxygen uptake (VO2 peak) and achieved it earlier than controls.
- O2 pulse was significantly lower throughout the exercise test in the T1DM group.
- No differences observed in baseline VO2, anaerobic threshold, minute ventilation, or spirometry.
Conclusions:
- Well-controlled adolescents with T1DM demonstrate reduced working capacity.
- Cardiorespiratory fitness may be impaired in pediatric T1DM despite adequate metabolic control.
