The present study investigated the effect of six weeks of endurance and resistance training on pulmonary indices, physical performance, and quality of life in COVID-19 patients after discharge from hospital.

Thirty six patients with COVID-19 (mean age: 38.76±0.98 years, mean weight: 81.86±2.88 kg) were selected. At the beginning and end of the study, pulmonary (FEV1, FVC, FEV1/FVC, and MVV), physical (6-minute walk test), quality of life (SF-36), and anthropometry tests were performed. The patients were divided into three groups: Endurance training (45 minutes at 60-75% estimated HR), Resistance training (45 minutes at 40-70% of I-RM), and controls. The intervention was conducted for 6 weeks (3 sessions). One-way ANOVA test was used for statistical analysis.

Findings indicated a significant increase in FEV1 (P=0.029), FVC (P=0.047), FEV1/FVC (P=0.043) in the endurance training group compared to the control group, while difference was observed in MVV (P=0.041) and FEV1/FVC (P=0.022) between endurance training and resistance training groups. The 6-minute test distance increased in the endurance training (P=0.0001) and resistance training (P=0.001) groups compared to the control group, but no difference was observed between the training groups (P=0.48). Endurance and resistance training programs induced significant improvements in physical performance (P=0.024 and P=0.09, respectively) and general health (P=0.022 and P=0.015, respectively) dimensions compared to the control group.

Moderate-intensity endurance training can improve pulmonary function, physical performance, and quality of life in patients with COVID-19 after discharge from hospital and can be used in rehabilitation programs of these patients.

 Exercise reduction of respiratory symptoms of asthma and Vitamin D by adjusting the immune system can have a significant effect on the health of asthmatic patients. The purpose of this study was to investigate the effect of short-term vitamin D supplementation following a session of increased activity on respiratory parameters and activity tolerance in women with mild asthma.

  This study was quasi-experimental based on pre-post test That Following the announcement of the call, on thirty asthma women volunteered in Ahwaz performed. Balk test for cardiopulmonary patients was used for increasing aerobic exercise. Supplementation with vitamin D tablets at a dose of 1000 units daily for six weeks. About evaluation of pulmonary function we used Vital Capacity (VC) and Maximum Voluntary Ventilation (MVV) indicators by Spirometry devises. In order to determine normality of the data was used Shapiro-Wilk's test, T-test was used to analyze the data.

   Results indicated that there was a significant difference between VC and MVV levels and Activity tolerance to pre-test, supplement and exercise levels after the intervention (P ≤ 0/05.(

 Taking vitamin D supplementation with aerobic exercise can improve respiratory function in asthmatic patients and increase tolerance to activity.

Despite the use of exercise therapy in patients with respiratory disease such as asthma, some researchers have emphasized on taking supplementation as a therapeutic approach. The aim of this research was to investigate the effect of a course of aerobic exercise and consumption of vitamin D supplementation (1000 IU) on respiratory indicators of patients with asthma.

This study was designed as a quasi-experimental investigation on a total of 32 female asthmatic patients with a mean age of 20-30 years. Subjects were classified into four eight-person groups: 1- (AT+S) group which had both aerobic training and supplementation consumption; 2- Aerobic training (AT) group that only participated in exercise training; 3- Group (S) that only consumed vitamin D supplementation; 4- Control (C) Group that had neither aerobic training nor supplementation consumption. Statistical analysis was performed by ANOVA and Bonferroni post-hoc test. Significant difference considered as p<0.05.

In this study, there was a significant difference in post test (p<0.001) between groups in case of maximum voluntary ventilation (MVV), peak expiratory flow rate (PEF) and maximum expiratory flow at 75% vital capacity (FEF75%) and Maximum expiratory flow between 25% to 75% vital capacity (FEF25%-75%). These indices increased in group AT and AT+S, whereas, they showed decrease in group S and C.

Our results indicated that aerobic exercise together with consumption of vitamin D supplementation for 8 weeks could improve the pulmonary function and level of aerobic performance of asthmatic patients and could be considered as a part of pulmonary rehabilitation programs for asthmatic patients.
