Is a running heart rate of around 80 beats normal

When running, a heart rate of around 80 beats per minute is usually low, which may be an abnormal situation. The normal range of heart rate during running is affected by factors such as age, exercise intensity, and physical fitness level, mainly due to low resting heart rate, insufficient exercise intensity, abnormal heart function, medication effects, measurement errors, and other reasons.

1. Low resting heart rate

People who undergo long-term endurance training may have a resting heart rate below 60 beats per minute, and the increase in heart rate during running is relatively small for this group of people. But even athletes with strong aerobic abilities should have a heart rate of over 100 beats per minute during moderate intensity running. If low heart rate persists for about 80 times, pathological factors such as sinus node dysfunction need to be investigated.

2. Insufficient exercise intensity

During walking or extremely low-intensity jogging, the heart rate may remain around 80 beats per minute, which is considered an ineffective exercise range. The effective fat burning heart rate should reach 60% -70% of the maximum heart rate, which is about 120-140 beats per minute for healthy adults. It is recommended to increase exercise intensity by adjusting speed and slope, or using training methods such as interval running.

3. Abnormal cardiac function

Diseases such as sinus bradycardia and atrioventricular block can cause the heart rate to not increase normally during exercise. May be accompanied by symptoms such as dizziness and fatigue, and electrocardiogram examination may reveal abnormalities such as prolonged PR interval and sinus arrest. In severe cases, a pacemaker needs to be installed, while mild patients can gradually improve through aerobic training.

4. Drug Effects

Taking beta blockers such as metoprolol, bisoprolol, and other antihypertensive drugs can inhibit heart rate elevation. Some anti anxiety drugs also have similar effects. This group of people needs to closely monitor their heart rate changes during exercise to avoid masking signals of excessive exercise due to medication effects. If necessary, adjust the medication plan under the guidance of a doctor.

5. Measurement Error

Optical heart rate watches may experience monitoring deviations in low temperature environments or when the wristband is too loose. It is recommended to manually measure and review the carotid or radial artery, count the pulse for 15 seconds, and multiply by 4 to convert. Immediate measurement after exercise may result in low values due to vasoconstriction, and should be retested after a 1-minute break.

It is recommended to wear professional heart rate equipment for continuous monitoring during running. For the general healthy population, the heart rate during moderate intensity running should be maintained at 120-150 beats per minute. If abnormal low heart rate occurs repeatedly and measurement errors are ruled out, 24-hour dynamic electrocardiogram, exercise load test and other examinations should be performed. Daily use can be combined with deep breathing training, alternating hot and cold baths, and other methods to improve the autonomic nervous system regulation function of the heart and avoid sudden high-intensity exercise. Middle aged and elderly people should pay special attention to sufficient warm-up before exercise, gradually improving their physical fitness starting from low-intensity aerobic exercise.
