Reference values of aerobic fitness in the contemporary paediatric population
- Cross-sectional study
- development and validation cohorts
Authors' conclusion
This study established reference Z-score values for paediatric cycloergometer VO2max using a logarithmic function of VO2max, height, and BMI, applicable to normal and extreme weights.
Study context
- Population
- Children aged 5 to 18 years from the general population, including extreme weights, undergoing cardiopulmonary exercise test (CPET)
- Participants
- 909 vs 232
- Exposure
- VO2max Z-score model vs existing linear equations
- Developmentn = 909
- Validationn = 232
- Outcome
- VO2max reference Z-score values
Main finding
As reported in the abstract
Best VO2max Z-score model
- For both sexes, the model using natural logarithms of VO2max, height and BMI was the best fit
- Z-score model applicable to normal and extreme weights and more reliable than existing linear equations, in internal and external validity analyses
Observational data: associations, not effects.
