Investigation of Respiratory Muscle Strength, Exercise Capacity, Physical Activity and Sleep Quality Level in Individuals With Covid-19 Infection

COVID-19 infection was identified in Wuhan, China at the end of 2019 and turned into a pandemic in a short time. In our country, the pandemic continues at full speed and patients are being treated in various clinical pictures. In its clinical classification, the World Health Organization (WHO) divides COVID-19 disease into four stages: mild symptomatic disease, pneumonia, severe pneumonia, acute respiratory distress syndrome (ARDS), sepsis and advanced stage with septic shock. Case reports and cross-sectional studies report a list of more than 200 different symptoms in the development of post COVID-19 syndrome. Shortness of breath, persistent smell and taste disturbances, fatigue and neuropsychological symptoms (headache, memory loss, slowed thinking, anxiety, depression and sleep disturbances) are the most commonly reported symptoms. Musculoskeletal symptoms such as pain (myalgia), muscle weakness, arthralgia and fatigue are also common. Exercise endurance tests are used to predict the prognosis of the disease in chronic lung diseases, to determine functional exercise capacity, to evaluate the response of the disease to treatment and to interpret the results of clinical trials. Covid-19-induced lung infections and long periods of isolation may have negative effects on respiratory muscle strength, pulmonary function values and physical activity level. It has been reported that only one week of bed rest can cause serious muscle loss of up to 20%. Covid-19 infection increases the likelihood of asthma-like symptoms. In some cases, pneumonia and increased dyspnea are also seen. When volleyball players with Covid-19 infection were examined, respiratory muscle strength and fev1/fvc values were lower than expected. When looking at the interaction between infections and sleep, it was observed that different infections had different effects on sleep, with some infections increasing the amount of sleep while others decreased it. The increase in inflammatory mediators associa
