Optimal Physical Activity Levels in Children with Chronic Lung Disease: A Research Study

This study evaluates the optimal levels of physical activity in children and adolescents suffering from chronic lung disease (CLD). With a focus on parameters such as VO2max, ventilatory equivalent for oxygen (VE/VO2), and exercise-induced bronchospasm (EIB), we analyze the correlation between aerobic fitness and physical activity levels. The research includes a control group and assesses pulmonary function through spirometry and exercise stress tests. Results indicate variations in lung function among participants with different types of chronic lung conditions.

  1. Clinical application • Dx exercise intolerance 1.1  VO2max   VO2 AT 1.2 RER >1.2 (HRmax is not achieved) 1.3 breathing reserve < 20% (N=20-40%) 1.4  SaO2 1.5 VE/VO2(ventilatory equivalent for oxygen)> 40 • Dx exercise-induced bronchospasm (EIB) • Aerobic fitness evaluation

  2. Research study Optimal level of physical activity in children and adolescent with chronic lung disease

  3. To study the optimal level of physical activityin children and adolescents with CLD Objectives

  4. Experimental design Normal (n=18) CLD (n=18) Hx & PE VO2 at AT  correlate with physical activity PFT - Spirometry - Lung volumes - DLco Exercise stress test

  5. Results Chronic lung diseases: - Chronic interstitial lung 1 - Post lobectomy 5 - Pulmonary hemosiderosis 1 - Fibrotic lung 3 - BPD 2 - Asthma moderate persistent 6

  6. Abnormal PFT • Obstructive lung 7 (FEV1 80.0 + 12.9%pred) • Restrictive lung 7 (TLC 63.7 + 12.5%pred) • Diffusion defect 1 (DLco/VA = 77 %pred) • Hyperinflation 9 (RV/TLC 38.9 + 6.5%pred)
