It is not accurate to say that the faster the heart rate the higher the calorie consumption, the faster the heart rate the faster the calorie consumption, but the amount of calorie consumption is also related to the time. If the daily exercise time is too short, even if the heart rate is fast, the total amount of calorie consumption will be reduced. Therefore, patients should exercise for a minimum of 30-60 minutes per day to achieve satisfactory calorie consumption. It is also dangerous to exceed the maximum heart rate, which is usually 220 minus the actual age of a normal person, if the heart rate is particularly fast. To burn calories efficiently, it is usually safer to ensure that the heart rate reaches 50-70% of the maximum heart rate. If the heart rate is too fast, close to or exceeding the maximum heart rate, the heart’s ejection capacity will be reduced, and it is easy to lead to cardiac arrest, or even life-threatening, so it is usually best to keep the heart rate at the optimal level of exercise.
