Too Much High-Intensity Exercise Could Hurt Heart Health
The Huffington Post | by Sarah Klein
On the heels of research suggesting too much running could lead to an earlier death, two new studies say too much high-intensity exercise could lead to heart problems.
The first, conducted by German researchers, followed more than 1,000 people mostly in their 60s, who had existing heart disease and had enrolled in an exercise program to prevent further heart health issues. As hypothesized, the least physically active people were at increased risk for heart problems and earlier death. But the most active group, those who did daily strenuous physical activity, also had increased risk of dying of heart problems than people who were active only two to four times a week, according to the study.
