This study aimed to determine how behavioural restrictions due to the emergency declaration following the coronavirus disease 2019 (COVID‐19) pandemic affect exercise tolerance and its outcomes in patients in Phase III cardiac rehabilitation programme. This is a multicenter retrospective cohort study. Participants in outpatient cardiac rehabilitation programmes and cardiopulmonary exercise testing before and after the emergency declarations were included. A total of 90 participants were included (median age 75.0 years, 69% male), and the changes in physical function and exercise tolerance were compared before and after the emergency declaration. Patients were divided into a decline‐in‐peak oxygen uptake (VO2) group and a nondecline‐in‐peak VO2 group. Comparison before and after the emergency declaration showed that the anaerobic threshold declined significantly and peak VO2 exhibited a downward trend. The decline‐in‐peak VO2 group consisted of 16 patients (17%) with better exercise tolerance, multiple comorbidities, and declined lower extremity muscle strength. These patients also had a higher rate of subsequent composite events (hazard ratio, 5.2; 95% confidence interval, 1.4–18.8, p = 0.01). Before and after the emergency declaration, the patient's exercise tolerance may decline, leading to a poor prognosis. This study suggests the importance of maintaining exercise tolerance during the COVID‐19 pandemic.
