Too Much of a Good Thing?

1 Intense Exercise Linked to Heart Arrhythmia

While exercise has repeatedly been shown to improve heart health and to reduce the likelihood of developing heart disease for most people, evidence is accumulating that too much intense and prolonged physical exertion may be counterproductive for heart health. A 2011 study of lifelong competitive endurance athletes aged 50 or older found that they had more scarring of the heart than their peers who exercised actively but not at a competitive level. And now, a study published in the European Heart Journal reports that among men, the more times someone had competed in the demanding 56-mile cross-country Swedish ski race called the Vasaloppet, and the faster their finishing times, the more often they were admitted to a hospital for abnormal heartbeat in the ensuing ten years.
