An athlete’s resting heart rate may be considered low when compared to the general population. A young, healthy athlete may have a heart rate of 30 to 40 bpm.
That’s likely because exercise strengthens the heart muscle. It allows it to pump a greater amount of blood with each heartbeat. More oxygen is also going to the muscles.
This means the heart beats fewer times per minute than it would in a nonathlete. However, an athlete’s heart rate may go up to 180 bpm to 200 bpm during exercise.
