Can Too Much Exercise Be Hazardous To Your Health and Your Heart?

Excessive endurance exercise can do long-term harm to the cardiovascular system

Excessive endurance exercise can do long-term harm to the cardiovascular system

Wait a minute; you have been harangued to get off the sofa, put down the chips and salsa, and get moving. Is that bad advice? Probably not. However, I do want to report on a study from Mayo Clinic that suggests that too much running may hurt you. If you are a runner there is nearly a 20% reduction in death over not running. However running more than 20 miles per week appears to cancel out that benefit. Jogging slowly decreases mortality risk, whereas running at a pace faster than 8-minute miles has been found to put extra stress on the heart. More than an hour of intense aerobic activity per day can cause serious heart problems. Many runners assume that if moderate exercise is good than more is better.

Bottom Line: Probably, like so much else in health, moderation is the watchword. Exercising more than one hour a day may not be good for your health or your heart. My suggestion is to do cross training and that is running mixed with biking, weight lifting, and even an occasional day of rest with no exercise.

Happy New Year to everyone. The Whiz
