Why To Exercise Today: Less Fear Of Dying In Flagrante Delicto


New research appears to bear out popular wisdom: Sex or “episodic” exercise like the snow shoveling many of us may face tomorrow do appear to briefly raise the risk of a heart attack.

But the study by Tufts Medical Center researchers just out in the Journal of the American Medical Association is by no means a justification for refraining from exercise. On the contrary: It also found that regular exercise significantly reduces those heart risks, so exercising today could mean lower risk if you exercise — or attempt certain other potentially strenuous activities — tomorrow.

The Los Angeles Times sums up the study here:

Researchers analyzed 14 studies looking at the effects of exercise and sex on sudden cardiac death and myocardial infarction, or heart attack. They found periodic physical activity was associated with a 3.5-times increased risk of heart attack, and occasional sexual activity was linked with a 2.7-times increased risk of heart attack. Periodic physical activity was also linked with an increased risk of sudden cardiac death.

However, the more exercise people did, the lower their risk of acute cardiac events. For each time someone exercised during the week, the relative risk of a bout of exercise prompting a heart attack decreased by about 45%, and for sudden cardiac death it decreased 30%.
