Individuals who have been confirmed by the previous SARS-COV 2 real-time reverse transcriptase polymerase chain reaction (RT-PCR) test to have coronovirus infection after the test will be included in a treatment program of 15 sessions, at least 3 sessions per week, with bicycle ergometry. After 15 sessions, exercise capacity will be re-evaluated using the cycling test, the aforementioned triceps and grip muscle strengths, V02 max, maximum conjugate (MET), maximum work (w), borg scale, maximum heart rate, test time parameters will be saved again after treatment. conditions: COVID-19 Pneumonia conditions: COVID-19 studyType: INTERVENTIONAL phases: NA allocation: NON_RANDOMIZED interventionModel: PARALLEL primaryPurpose: TREATMENT masking: NONE count: 41 type: ACTUAL name: Kardiopulmonary exercise test (Quark KPET C12x/T12x device connected to the Omnia version 1.6.8 COSMED system) name: Peripheral muscle strength measurement (microFET3 (Hoggan Health Industries, Fabrication Enterprises, lnc) and JAMAR hydraulic hand dynamometer (Sammons Preston, Rolyon, Bolingbrook). name: Standard exercise tolerance test (a bicycle ergometer and recorded through the ergoline rehabilitation system 2 Version 1.08 SPI.) name: Aerobic exercise training (a bicycle ergometer and recorded through the ergoline rehabilitation system 2 Version 1.08 SPI.) measure: Assessment of Triceps muscle strength by using the Micro FET3 muscle strength device measure: Assessment of Maximum work (watts) ın the standard exercise tolerance test using a bicycle ergometer and recording it via ergoline rehab system 2 Version 1.08 SPI. measure: Assessment of Metabolic Equivalent (MET) in the standard exercise tolerance test using a bicycle ergometer and recording it via ergoline rehab system 2 Version 1.08 SPI. measure: Assessment of VO2peak (ml/kg/min) in the exercise tolerance test using a bicycle ergometer and recording it via ergoline rehab system 2 Version 1.08 SPI. measure: Assessment of VO2peakpredictive (%) in the standard exercise tolerance test using a bicycle ergometer and recording it via ergoline rehab system 2 Version 1.08 SPI. measure: Assessment of Hand grip strength (kg) by using a JAMAR hydraulic hand dynamometer (Sammons Preston, Rolyon, Bolingbrook). measure: Assessment of Exchange Ratio(RER ) by using cardiopulmonary exercise test, a Quark KPET C12x/T12x device connected to the Omnia version 1.6.8 COSMED system, measure: Assessment of Anaerobik Treshold (VAT) by using cardiopulmonary exercise test with a Quark KPET C12x/T12x device connected to the Omnia version 1.6.8 COSMED system, measure: Assessment of Maximum Oxygen Capacity (VO2peak) by using cardiopulmonary exercise test with a Quark KPET C12x/T12x device connected to the Omnia version 1.6.8 COSMED system, measure: Assessment of Maximum Oxygen Capacity at Ventilatory Anaerobic Threshold (VO2AT) by using cardiopulmonary exercise test with a Quark KPET C12x/T12x device connected to the Omnia version 1.6.8 COSMED system, measure: Assessment of Carbon Dioxide Ventilatory Equivalent (VE/CO2) by using cardiopulmonary exercise test with a Quark KPET C12x/T12x device connected to the Omnia version 1.6.8 COSMED system, measure: Assessment of Heart Rate Recovery (HRR) by using cardiopulmonary exercise test with a Quark KPET C12x/T12x device connected to the Omnia version 1.6.8 COSMED system, measure: Assessment of Heart Rate Recovery at first minute (HRR1) by using cardiopulmonary exercise test with a Quark KPET C12x/T12x device connected to the Omnia version 1.6.8 COSMED system, measure: Assessment of quadriceps muscle strength by using the Micro FET3 muscle strength device measure: Assessment of Physical activity by using the International Physical Activity Questionnaire (IPAQ) measure: Assessment of Test Duration (min) in the standard exercise tolerance test using a bicycle ergometer and recording it via ergoline rehab system 2 Version 1.08 SPI. measure: Assessment of Perceived Difficulty by using the Borg Scale measure: Assessment of Maximum heart rate (beats/min) in the standard exercise tolerance test using a bicycle ergometer and recording it via ergoline rehab system 2 Version 1.08 SPI. measure: Assessment of Systolic and diastolic blood pressure (mmHg) by using a blood pressure monitor measure: Assessment of resting heart rate (beats/min) by using a a pulse oximeter sex: ALL minimumAge: 18 Years maximumAge: 55 Years stdAges: ADULT facility: Zonguldak Bülent Ecevit University city: Zonguldak zip: 67100 country: Turkey lat: 41.45139 lon: 31.79305 hasResults: False
