Athlete's<unk>  most often does not have any physical symptoms, although an indicator would be a consistently low resting<unk>  rate. Athletes with AHS often do not realize they have the condition unless they undergo specific medical tests, because athlete's<unk>  is a normal, physiological adaptation of the body to the stresses of physical conditioning and aerobic exercise. People diagnosed with athlete's<unk>  commonly display three signs that would usually indicate a<unk>  condition when seen in a regular person: bradycardia, cardiomegaly, and cardiac hypertrophy. Bradycardia is a slower than normal<unk> beat, at around 40–60 beats per minute. Cardiomegaly is the state of an enlarged<unk> , and cardiac hypertrophy the thickening of the muscular wall of the<unk> , specifically the left ventricle, which pumps oxygenated blood to the aorta. Especially during an intensive workout, more blood and oxygen are required to the peripheral tissues of the arms and legs in highly trained athletes' bodies. A larger<unk>  results in higher cardiac output, which also allows it to beat more slowly, as more blood is pumped out with each beat. Another sign of athlete's<unk><unk>  is an S3 gallop, which can be<unk>  through a stethoscope. This sound can be<unk>  as the diastolic pressure of the irregularly shaped<unk>  creates a disordered blood flow. However, if an S4 gallop is<unk> , the patient should be given immediate attention. An S4 gallop is a stronger and louder sound created by the<unk> , if diseased in any way, and is typically a sign of a serious medical condition.
