Example ultrasound of an athlete. Athlete's heart most often does not have any physical symptoms, although an indicator would be a consistently low resting heart rate.. Athletes with AHS often do not realize they have the condition unless they undergo specific medical tests, because athlete's heart is a normal, physiological adaptation of the body to the stresses of physical conditioning and ...
This response can be dramatic; in trained athletes have hearts that have left ventricular mass up to 60% greater than untrained subjects. Rowers, cyclists, and cross-country skiers tend to have the largest hearts, with an average left ventricular wall thickness of 1.3 centimeters, compared to 1.1 centimeters in average adults.
The heart gets bigger and more efficient in an endurance athlete. For a resistance athlete, the whole heart gets modestly thicker. This means an endurance athlete might have a lower resting heart ...

The AHA also says that athletes can have resting heart rates as low as 40 bpm. However, heart rates can vary depending on what you’re doing and will typically spike during exercise.
Elite long-distance runners often have larger hearts and decreased resting heart rates that enable them to achieve greater aerobic capacities. Increased dimensions of the heart enable an individual to achieve a greater stroke volume. A concomitant decrease in stroke volume occurs with the initial increase in heart rate at the onset of exercise.

The heart is often described as the size of a fist: 12 cm (5 in) in length, 8 cm (3.5 in) wide, and 6 cm (2.5 in) in thickness, [8] although this description is disputed, as the heart is likely to be slightly larger. [18] Well-trained athletes can have much larger hearts due to the effects of exercise on the heart muscle, similar to the ...
