About

Coronavirus-2019 (COVID-19) is a new virus that emerged in December 2019 and spread quickly all over the world. Problems such as hypoxia, dyspnea, increased fatigue, decreased exercise capacity and respiratory muscle strength occur in COVID-19 patients.In addition, abnormalities in skeletal muscles due to systemic inflammation, mechanical ventilation, sedation and prolonged bed rest in hospital and intensive care patients cause decreased exercise capacity.

Full description

Dyspnea is one of the most common long-term symptoms in COVID-19 patients. It has been determined that dyspnea that persists three and six months after hospital discharge is associated with peak oxygen consumption in hospitalized and discharged COVID-19 patients, while peak oxygen consumption decreases in patients with dyspnea.The effects of inspiratory muscle training have been investigated in different lung diseases. In these studies, it was reported that inspiratory muscle training increased respiratory muscle strength and endurance, exercise capacity and quality of life, and decreased fatigue and dyspnea. In addition, it has been found that high-intensity interval aerobic exercise training increases exercise capacity in patients with lung disease and heart failure.In heart failure patients, it was found that high-intensity interval aerobic exercise training increased peak oxygen consumption more than moderate-intensity continuous aerobic exercise training.Patients need exercise training because symptoms such as lung involvement, decreased exercise capacity, dyspnea and fatigue continue after the disease in patients who have had COVID-19.

The aim of this study is to comparison of the effects of inspiratory muscle training and high intensity interval aerobic exercise training in patients with COVID-19.

Primary outcome measurement will be oxygen consumption (cardiopulmonary exercise test).

Secondary outcome will be muscle oxygenation (Moxy device), physical activity level (multi sensor activity device), pulmonary function (spirometer), functional exercise capacity (six-minute walk test), respiratory (mouth pressure device) and peripheral muscle (hand-held dynamometer) strength, inspiratory muscle endurance (incremental threshold loading test), functional status (Post-COVID-19 Functional Status Scale), dyspnea (London Chest Daily Living Activity Scale), fatigue (Fatigue Severity Scale) and quality of life (Saint George Respiratory Questionnaire).
