Abstract: Objective: To explore the effect of coronavirus on cardiopulmonary fitness and muscular fitness in infected patients, and to provide basis for the later exercise rehabilitation of patients with new coronavirus pneumonia (COVID-19). Methods: PubMed, Web of Science, CNKI and other databases were used to search existing published domestic and foreign related literature on the relationship between coronavirus and patients' cardiopulmonary fitness and muscular fitness, according to the non-randomized Newcastle-Ottawa scale. (NOS) Perform quality evaluation on the included literature, extract relevant information from the literature, and conduct a comprehensive analysis of systematic evaluation. Results: A total of 23 articles were included. The average score of NOS in 22 non-randomized studies was 6.9, and one randomized controlled study had a low risk of bias. The results showed that the patients' cardiopulmonary fitness and muscular fitness indicators were lower than those of healthy people after discharge. The patients' cardiopulmonary fitness gradually recovered within 3 years after discharge, but the maximum oxygen uptake (VO2 max) did not fully recover within 3 years, and the 6-minute walking distance (6MWD) did not fully recover within 1 year. The patient's muscular fitness index grip strength, sit-ups, and push-ups were lower than those in the healthy group 2 weeks after discharge. Exercise intervention can significantly improve patients' VO2 max, 6MWD, grip strength, sit-ups and push-ups. The number of patients diagnosed and hospitalized days were significantly related to grip strength and 6MWD. Conclusion: Coronavirus can cause damage to cardiopulmonary and muscular fitness in patients with infection. Cardiopulmonary fitness and muscular fitness are increasing after discharge, but it still takes a long time to fully recover. Changes in cardiopulmonary fitness and muscular fitness in patients were affected by factors such as the number of days diagnosed and the length of hospital stay.
