Fiziksel aktif bireylerde COVID-19 enfeksiyonunun pulmoner parametreler, fonksiyonel egzersiz kapasitesi ve kor stabilite üzerine etkileri

This study investigated the effects of COVID-19 infection on lung volumes, respiratory muscle strength, dyspnea, functional exercise capacity, core stability, and quality of life in physically active individuals. This study included 50 (32.56±.9.73) healthy and physically active volunteers from Bezmialem Vakıf University, Dragos Hospital, and Physical Therapy Clinic members between January and March 2022. A total of 50 healthy individuals (24 F, 26 F, 32.56±.9.73 years) applied to the Bezmialem Dragos Hospital Physical Therapy Clinic and did at least three months of exercise and moderate physical activity per week before being included in the study. We included 25 outpatients of COVID-19 infection without hospitalization and 25 healthy adults. Lung volumes (spirometry), respiratory muscle strength (Maximum Inspiratory Capacity (MIP) and Maximum Expiratory Capacity (MEP)), dyspnea (Modified Medical Research Council Scale), functional exercise capacity (six-minute walk test (6MWT)), core stability (McGill core endurance test ) and quality of life (Short Form Survey -36) were assessed. The findings of this study revealed that exercise capacity (p=0.045), right lateral (p=0.014), and left lateral (p=0.023) core endurance and quality of life test (p =0.040) decreased in physically active COVID-19 survivors. Furthermore, volunteers in the COVID-19 Group push more dyspnea (p= 0.045) than the Control Group. Moreover, there was a positive correlation between 6MWT and McGill Lateral Right and Left core endurance tests, McGill Core endurance parameters, and MIP value (p<0.05). Thus, physically active individuals may experience a decrease in their functional capacity and core endurance after COVID-19 infection, and this may lead to experiencing more dyspnea. Key words: coronavirus, respiratory functions, core endurance, physical activity, quality of life.
