A running heart rate of 180 beats per minute is on the fast side. Under normal circumstances, the running heart rate should be maintained at 110~150 beats per minute, and the optimal heart rate that can be tolerated by different age groups is different. The maximum heart rate for normal adults is 220-age beats per minute, and the maximum heart rate for the elderly or patients with coronary heart disease or arrhythmia is 170-age beats per minute. The heart rate varies depending on the intensity of the exercise. Generally, the heart rate of moderate-intensity exercise is 60% to 80% of the maximum heart rate. When healthy adults exercise, the heart rate increases with the exercise load, and the amount of beat volume also increases. Excessive heart rate during exercise will increase the burden on the heart and bring about adverse effects. Moderate exercise is good for the body, if the exercise is strenuous and produce discomfort must immediately rest and go to the hospital to do the relevant examination.
