Background Coronavirus disease 2019 (COVID-19) represents a wide range of clinical manifestations, even if mild disease severity. It has been known that pulmonary function is affected by COVID-19 during infection and mid-to-long term. However, there is inadequate evidence about extrapulmonary features in post-COVID-19 patients. Aims This study aimed to investigate extrapulmonary features in post-COVID-19 patients who recovered from mild and moderate disease severity in the mid-term. Methods This cross-sectional study was carried out after at least 12 weeks from the COVID-19 diagnosis. Disease severity was defined using criteria for clinical severity of confirmed COVID-19 pneumonia. The peripheral muscle strength was measured using the dynamometer. Physical performance was assessed with five times sit-to-stand and 4-m gait speed. Physical activity level (PAL), mood, and sleep quality were assessed with the International Physical Activity Questionnaire, Hospital Anxiety, and Depression Scale, and Pittsburgh Sleep Quality Index, respectively. Results A total of 48 participants with post-COVID-19 (39.2 ± 7.9 years, 54.2% women) were included in the study. Handgrip and quadriceps weakness was observed in 39.6% and 35.4% of the participants, respectively. PAL was low in 39.6%, moderate in 33.3%, and high in 27.1% of the participants. Anxiety, depression, and poor sleep quality were observed in 33.3%, 29.2%, and 50% of the participants, respectively. Conclusions Extrapulmonary features are adversely affected in a substantial proportion of post-COVID-19 patients who recovered from mild and moderate disease severity in the mid-term. Comprehensive assessment and appropriate intervention strategies should also be considered for non-severe post-COVID-19 patients.

Introduction and objective: Asthma, is the most common chronic inflammatory disease in childhood period. It can affect the daily life to an advanced level and may become vital. The purpose of this study is to compare physical fitness and anaerobic capacity in asthmatic children (AC) and non-asthmatic children (NC). Materials and methods: A total of 47 children participated in the study; 25 individuals with mild to moderate asthma and 22 healthy children were assessed. The assessed variables consist pulmonary function and peripheral muscle strength (PMS). Additionally, physical fitness was evaluated by using fitnessgram test battery, which includes body composition, modified shuttle walk test (MSWT), curl-up test, push-up test, and sit and reach test variables. Anaerobic capacity was measured with wingate anaerobic capacity test (WAnT) and counter-movement jump (CMJ) using a tri-axial accelerometer. Results: FEV1/FVC ratio (p = 0.01), MSWT (p = 0.001), push-up test (p = 0.01), and WAnT peak power (p = 0.05) were measured significantly to be found reduced in AC compared with that of NC. Between the two groups, PMS, curl-up test, sit and reach test, and CMJ were not significantly different (p = 0.05). High to moderate positive correlation was found among WAnT, CMJ parameters and FEV1, fat-free body mass (FFM), dominant handgrip, and quadriceps strengths (p = 0.05). Conclusions: Physical fitness level and anaerobic capacity were lower in AC compared with that of NC. Physical fitness parameters and anaerobic exercise capacity should be evaluated on the physiotherapy and rehabilitation program in AC.
