Peak oxygen uptake (VO₂ max) is a key measure of cardiorespiratory fitness, yet its assessment typically requires maximal exertion testing with expensive equipment in a hospital setting. This limits routine monitoring and early detection of fitness-related health concerns, especially in children.
This study evaluates whether the Corsano CardioWatch 287-2B can accurately estimate peak VO₂ (pVO₂) during workouts performed via the Corsano app. Results will be compared with those from gold-standard hospital-based cardiopulmonary exercise tests (CPET).
If proven accurate, Corsano’s wearable could be used to monitor physical fitness in clinical and home settings, supporting pediatric rehabilitation, early intervention, and lifestyle monitoring.
Study Objectives
Primary Outcome
• Agreement between pVO₂ estimates from the Corsano app and maximal exertion CPET values in pediatric patients.
Secondary Outcome
• Feasibility and acceptability of app-based exercise protocols in children
Study Design
This is a prospective validation study. Each participant completes a standardized hospital-based maximal exercise test while also performing a Corsano-guided workout. Peak VO₂ estimates from both are compared for accuracy. Trained clinicians at the SHTC unit supervise all assessments.
Inclusion Criteria
• Children aged 6–17 years are eligible for VO₂ max testing
• Capable of understanding and completing both exercise tests
• Parental consent and child assent provided
Exclusion Criteria
• Medical contraindications to exertion testing
• Inability to wear the Corsano wristband
