The Myocardium, which provides the muscle needed to create the pumping action that drives the blood through the body. Rigorous physical activity requires an increase from the body of blood to the muscles (systemic circulation). Overtime the heart adapts to this regular need and often the athlete's heart is larger than a non-athlete's and their heart rate is slower at rest as well to prepare the body for exercise.
