Effect of Respiratory Versus Aerobic Training on Respiratory and Immunity Efficiency in Recovered COVID- 19 Patients

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.

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.

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

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.

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.

It is a 0 to 10 rated numerical score used to measure dyspnea as reported by the patient during six minute walk test

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)

Inclusion Criteria: Patients recovered from COVID -19 infection. Patients with body mass index 25 - 35 kg/m2 Patients previously diagnosed with chest symptoms of COVID- 19 infection. Patients' body temperature less than 37.5 Blood oxygen saturation ≥95% Exclusion Criteria: Smokers Patients with Myocardial infarction Patients with diabetes. Patients with autoimmune disease.
