Answer:
False. Endurance athletes may have low resting heart rates, but their systolic volume is higher than that of a normal person.
Explanation:
People who perform intense physical exercise should have mechanisms that help keep their vital signs stable and allow them to meet the demand for oxygen and glucose to muscle tissue.
In trained people, the resting heart rate is usually low, even up to 40 beats per minute - making the increase in this frequency during exercise not dangerous. In the same way, the amount of blood that the heart pumps should be greater compared to an untrained person.
- A healthy and untrained person usually has a heart rate between 60 and 90 beats per minute (average of 75 beatsminute) and a stroke volume around 60 liters per minute.
- An endurance athlete has a heart rate between 40 and 50 beats per minute at rest, and his stroke volume is greater than 60 liters per minute.
The relationship between heart rate and stroke volume is called cardiac output, and its formula is <em>CO = HR × SV</em>. <u>In athletes cardiac output is higher</u>.
