A Community-Based Swimming and Inspiratory Muscle Training Intervention to Promote Physical Activity and Asthma Control in Children With Mild Asthma

NCT07394127

CompletedNA

Sponsor: Gümüşhane Universıty

Conditions: Asthma Control, Asthma, Asthma Chronic

Interventions: Swimming Training Only (Control Group), Swimming + Inspiratory Muscle Training (Experimental Group)

Countries: Turkey (Türkiye)

This randomized controlled trial investigated the effects of adding inspiratory muscle training (IMT) to a structured swimming program on pulmonary function, respiratory muscle strength, ventilatory capacity, perceived exertion, and asthma control in children with mild persistent asthma. Thirty children aged 8-11 years were randomly assigned to either a swimming plus IMT group or a swimming-only group. Both groups participated in a supervised 4-week swimming program, while the experimental group additionally performed IMT twice daily. Pulmonary function tests, respiratory muscle strength, and Childhood Asthma Control Test (C-ACT) scores were assessed before and after the intervention.
