Explanation of the exercise procedure. Vital signs, including blood pressure and heart rate, were checked, followed by stretches for 10 minutes as a gradual warm‐up before exercise. The duration of continuous exercise (an ergometry with a modified anaerobic threshold [AT] level) was ≈30 minutes without interval, and vital signs were checked by medical staff repeatedly, every 10 minutes. Exercise was discontinued when blood pressure during exercise was >150/100 mm Hg. The duration of the gradual cooling‐down period after exercise was ≈10 minutes. Patients were recommended to consume water, according to their medical status, before checkout.
