Abstract
Evidence clearly points to a beneficial cardio-protective effect of regular endurance exercise or aerobic type activities. However, each individual exercise bout represents a period of elevated cardiac risk. This increased risk may be particularly pertinent to older people when combined with a lowered blood flow to the brain and the progression of coronary artery disease. The exact nature of the responses to, and risks from, athletic participation in prolonged exercise bouts (such as a marathon) in older athletes is not clear. Recent studies have reported a reduction in left ventricular systolic (contractile) and diastolic (recovery) function, as well as elevated blood-borne markers of cardiac damage, following prolonged exercise in young (
