The efficacy of aerobic training in improving the inflammatory component of asthmatic children. Randomized trial

Area of Science:

• Pediatric Pulmonology
• Exercise Physiology
• Clinical Immunology

Background:

• Asthma is a chronic respiratory condition affecting children, with limited research on exercise's impact on inflammation and functional outcomes.
• Aerobic exercise is known to benefit cardiovascular health, but its specific effects on pediatric asthma require further investigation.

Purpose of the Study:

• To evaluate the impact of a 6-week aerobic exercise program on inflammatory markers, functional capacity, respiratory muscle strength, quality of life, and symptom scores in children with moderate asthma.

Main Methods:

• A 6-week randomized controlled trial involving 33 children (6-17 years) with moderate asthma.
• Participants were assigned to either an aerobic training group (n=14) or a control group (n=19).
• Primary outcomes included serum cytokine levels (IL-17, IFN, TNF, IL-10, IL-6, IL-4, IL-2) assessed by flow cytometry; secondary outcomes included the 6-minute walk test, pulmonary function, quality of life, and asthma-free days.

Main Results:

• Aerobic training did not significantly alter serum cytokine patterns.
• The exercise group showed significant improvements in functional capacity (p<0.01), peak expiratory flow (p=0.002), maximal inspiratory pressure (p=0.005), and maximal expiratory pressure (p<0.01).
• Quality of life scores (PAQLQ) improved across all domains, and participants reported more asthma-free days (p=0.012) and reduced dyspnea (p<0.01).

Conclusions:

• Six weeks of aerobic exercise in children and adolescents with asthma did not change plasma cytokine patterns.
• Aerobic exercise significantly improved functional capacity, respiratory muscle strength, quality of life, and asthma-related symptoms.
• Aerobic training presents a viable non-pharmacological intervention to enhance physical function and well-being in pediatric asthma patients.
