Running: Too much of a good thing?Whether you prefer running outdoors or inside on a new or used treadmill, a pair of new studies suggests running too often or too fast could actually be detrimental to your heart health.
According to The Wall Street Journal, one study followed more than 52,000 individuals for 30 years. While the runners in the group were found to have a nearly 20 percent lower risk of dying compared to non-runners overall, the study found that those who ran more than 20 to 25 miles each week did not see any mortality benefits.
The second study, which is published in the journal Heart, found that those who run over eight miles per hour do not live as long as those who run slower.
"Running too fast, too far and for too many years may speed one's progress toward the finish line of life," researchers said in an editorial written for the journal Heart, according to the newspaper.
While some experts dispute the conclusions of the studies, it's important to remember that exercising has been proven to offer significant health benefits overall. Regular physical activity has been shown to lower the risk of heart disease, hypertension, diabetes and even cancer.
Current guidelines suggest adults strive to get at least 150 minutes of moderate-intensity aerobic activity each week to maintain optimum health.
