Below the lower limit of 60%, the effect of burning fat will not be achieved and glycogen will be consumed; If it is higher than 80%, it will produce more muscles. If you can't continue this high-intensity exercise, you will easily get fat in the future, and if you continue, it will easily lead to new sports injuries.

Extended data:

Heart rate refers to the number of heartbeats per minute of normal people in a quiet state, also known as quiet heart rate, which is generally 60 ~ 100 beats per minute, and may vary among individuals due to age, gender or other physiological factors. Generally speaking, the younger the age, the faster the heart rate, the slower the heart rate of the elderly than the young, and the faster the heart rate of women than men of the same age. These are normal physiological phenomena. In a quiet state, the normal heart rate of adults is 60 ~ 100 beats/min, and the ideal heart rate should be 55 ~ 70 beats/min (the heart rate of athletes is slower than that of ordinary adults, generally about 50 beats/min).

Heart rate changes are closely related to heart disease. If the heart rate is greater than 160 beats/min, or less than 40 beats/min, it is more common in patients with heart disease. As usual, accompanied by palpitation, chest tightness and other discomfort. It should be examined in detail as soon as possible in order to treat the cause.

1. tachycardia

When adults are at rest, the heart rate exceeds 100 beats/min (generally not more than 160 beats/min), which is called sinus tachycardia. It is common after excitement, excitement, smoking, drinking or drinking strong tea or coffee, or under pathological conditions such as infection, fever, shock, anemia, hypoxia, hyperthyroidism, heart failure, or when atropine is used.

2. Bradycardia

When the adult's heart rate is lower than 60 beats/min (generally more than 45 beats/min), it is called sinus bradycardia, which can be seen in healthy people and athletes who have been engaged in heavy physical labor for a long time; Or in hypothyroidism, intracranial hypertension, obstructive jaundice and excessive digitalis, quinidine or propranolol. Sick sinus syndrome and atrioventricular block should be considered if the heart rate is lower than 40 beats/min. If the pulse intensity is unequal and uneven, and the pulse rate is less than the heart rate, atrial fibrillation should be considered.

3. Correct treatment of sinus bradycardia

Many people will have sinus bradycardia with arrhythmia, which is normal for most people, so don't worry too much. Sinus bradycardia refers to a person whose heart rate is lower than 60 beats/min. Whether this symptom will appear or not is related to the frequency of bradycardia and the causes of bradycardia. In a quiet state, if the adult's heart rate is between 50 and 60 beats per minute, there will generally be no obvious symptoms.

Especially for some well-trained athletes and people who have been engaged in manual labor for a long time, even if the heart rate is about 40 beats/minute in a quiet state, there will be no obvious symptoms. However, if the average person's heart rate is between 40 and 50 beats per minute, there will be symptoms such as chest tightness, fatigue and dizziness. If the heart rate drops to 35 to 40 beats/min, hemodynamic changes will occur, which will affect the blood supply to the heart and brain organs, leading to chest pain, dizziness, syncope and even sudden death.

If you don't feel any discomfort, don't pay attention to the "sinus bradycardia with arrhythmia" mentioned in the electrocardiogram, but if you have discomfort symptoms such as chest tightness, fatigue and dizziness, you should go to the hospital immediately for further examination, such as dynamic electrocardiogram and color Doppler echocardiography, to understand the causes of bradycardia. If the heartbeat is too slow, you can install a pacemaker to relieve symptoms and improve the prognosis.
