Respiratory Muscle Training and Walking Exercise in Women Recovering From COVID-19 Pneumonia

CompletedNA

Sponsor: Hitit University

Conditions: COVID-19 Pneumonia, Respiratory Symptoms

Interventions: Respiratory Muscle Training, Walking Exercise

Countries: Turkey (Türkiye)

This experimental study was designed to investigate the effects of respiratory muscle training and walking exercise on selected blood, respiratory, functional, dyspnea, sleep quality, and quality-of-life outcomes in women who had recovered from COVID-19-related lung inflammation/pneumonia. The study included women aged 20 to 45 years who had experienced COVID-19 with pneumonia, reported dyspnea, and had reduced quality of life. A total of 80 female participants were divided into four groups: respiratory muscle training plus walking exercise, respiratory muscle training alone, walking exercise alone, and a control group, with 20 participants in each group. Measurements were performed before and after the intervention period. The assessments included pulmonary function testing, maximal inspiratory pressure, the 6-minute walk test, the modified Borg scale for dyspnea, the Nottingham Health Profile, the Pittsburgh Sleep Quality Index, and selected blood parameters. The study aimed to determine whether respiratory muscle training, walking exercise, or their combination could improve respiratory function, inspiratory muscle strength, functional capacity, dyspnea, sleep quality, quality of life, and blood-related parameters in this population.
