Summary

This study were to investigate the effects of multiple breathing training on pulmonary function, respiratory muscle strength, chest expansion, fractional exhaled nitric oxide (FeNO), aerobic capacity, and dyspnea symptoms in older adults.

Detailed description

The study included 26 male and female older adults aged 60-75 years, who were divided into a control group (n = 13) that maintained usual daily activities and an experimental group (n = 13) that received multiple breathing training. The independent variable was multiple breathing training. Dependent variables included lung function (FVC, FEV₁, FEV₁/FVC, MVV), respiratory muscle strength (MIP, MEP), chest expansion, fractional exhaled nitric oxide (FeNO), aerobic capacity, and dyspnea assessment.

Conditions

• Older Adults (60 - 85 Years Old)

Interventions

Type	Name	Description
OTHER	Multiple breathing training	The multiple breathing training program consisted of five structured breathing exercises designed to improve inspiratory muscle strength, expiratory muscle strength, and breath control. Each exercise was performed for three sets, and the total training duration was approximately 40 minutes per session. The program included the following components: Inspiratory Muscle Training (PowerBreathe device): Participants performed resisted inhalation to strengthen the inspiratory muscles (10 repetitions per set). Expiratory Muscle Training (Balloon with control device): Participants exhaled into a balloon while maintaining pressure according to their measured maximal expiratory pressure (MEP) (10 repetitions per set). Inspiratory Training (Tri-Flow device): Participants inhaled through the device to elevate and maintain the floating balls, promoting sustained inspiratory effort (10 repetitions per set). Expiratory Training (Windmill device): Participants exhaled to rotate the windmill, e
