This study will be conducted on eighty patients of both sexes with age ranging from 35 to 45years. The will be recovered from COVID-19 infection with chest symptoms. They will be selected from Nasr city police authority hospital. They will be randomly assigned into 3 equal groups.
This study will be conducted on eighty patients of both sexes with age ranging from 35 to 45years. The will be recovered from COVID-19 infection with chest symptoms. They will be selected from Nasr city police authority hospital. They will be randomly assigned into 3 equal groups. Participants will be assigned into 3 groups equal in number (group A, group B, group C) Group A (Respiratory Training Group) : It will include 30 patients of both sexes, recovered from COVID-19 infection. In addition to medical drugs, they will receive respiratory training for 6 weeks. Group B : (Aerobic Training Group) : It will include 30 patients of both sexes, recovered from COVID-19 infection. In addition to medical drugs, they will receive aerobic training for 6 weeks Group C : (control group) :It will include 20 patients of both sexes, recovered from COVID-19 infection on medical drugs only will receive no exercise as control group.

Respiratory training in form of : Diaphragmatic breathing,Segmental breathing, Incentive spirometer:
aerobic exercises are customized according to the patient's underlying disease and residual dysfunction. These exercises will include walking on treadmill. After an initial, 5-minute warm-up phase performed on the treadmill at a low load, each endurance training session lasted 30 minutes and ended with 5-minute recovery and relaxation phase. A total of 3-5 sessions are carried out per week. Patients who are prone to fatigue should perform intermittent exercises

Complete blood picture
A venous blood sample will be taken to be analyzed in the laboratory
Time frame: change from baseline at 6 weeks
Arterial blood gases
arterial blood sample will be assessed
Time frame: change from baseline at 6 weeks
6-minute walk Distance
patient will be instructed to walk as fast as long as possible, in a 30 meters obstacle- free corridor, limited by turnaround cones. Standardized verbal encouragement will be given every minute. After 6 min, patient will be instructed to stop, and the total distance will be measured, rounding to the nearest meter.
Time frame: change from baseline at 6 weeks
Breath-hold test
A rough index of cardiopulmonary reserve measured by the length of time that a person can voluntarily stop breathing; normal duration is 30 seconds or longer; diminished cardiac or pulmonary reserve is indicated by a duration of 20 seconds or less.
Time frame: change from baseline at 6 weeks
Oxygen saturation
Percentage of haemoglobin saturated with oxygen measured by pulse oximeter
Time frame: change from baseline at 6 weeks
Borg Dyspnea Scale score
It is a 0 to 10 rated numerical score used to measure dyspnea as reported by the patient during six minute walk test
Time frame: change from baseline at 6 weeks
Maximum oxygen consumption
Maximum oxygen consumption(VO2 max): Results of (6MWT) was used to calculate Vo2 max by using Cahalin equation as follows; Vo2 max = 0.03x distance in meters +3.98, in which distance is obtained from (6MWT)
