Athletes and normal adults, the heart rate is 60 ~ 100 times / min, only due to long-term large-scale exercise, so that the heart rate is lower than normal.
Heart rate is an important physiological indicator reflecting the function of the circulatory system, the heart rate of normal adults in a quiet state is about 60~100 beats/minute. Athletes and normal people compared to a larger output per beat, low heart rate in quiet, myocardial oxygen uptake is lower, the heart is in a good state of energy conservation, maintaining a good cardiac reserve, which is conducive to the full mobilization of skeletal muscle in the state of exercise.
The reason for the low heart rate of athletes may be that long-term systematic training leads to changes in the control of the sympathetic and vagus nerves innervating the heart over the sinus node and the sensitivity of the nerves innervating the heart, thus lowering the heart rate of athletes.
It is recommended that appropriate physical exercise for the general population can improve cardiorespiratory reserve capacity, which is beneficial to health.
