A Community-Based Swimming and Inspiratory Muscle Training Intervention to Promote Physical Activity and Asthma Control in Children With Mild Asthma
Sponsor: Gümüşhane Universıty
Summary
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.

Interventions
Swimming Training Only (Control Group)
Participants completed a supervised swimming training program for 4 weeks, consisting of three 60-minute sessions per week. Sessions included warm-up, main swimming exercises, and cool-down breathing exercises. Exercise intensity was maintained at approximately 65% of maximal heart rate.
Swimming + Inspiratory Muscle Training (Experimental Group)
Participants completed the same swimming training program as the control group. In addition, inspiratory muscle training was performed using a threshold pressure-loading device. IMT was conducted twice daily, starting at 30% of maximal inspiratory pressure and progressively increased by 5% weekly, over a 4-week period.
