Finally, a study supporting all of us lazy people. Running is bad! Well…..not really.
Too much rigorous exercise is bad for your health, a study by British Journal Heart says. In an article by Active.com “The editorial authors reviewed decades’ worth of research on the effects of endurance athletics. They found numerous studies that showed that moderate exercise was good, but excessive exercise was damaging. For instance, in one German study published in European Heart Journal, researchers compared the hearts of 108 chronic marathoners and sedentary people in a control group. Surprisingly, the runners had more coronary plaque buildup, a risk factor for heart disease.”(Active). A study by Medicine and Science in Sports and Exercise also revealed after a study of more than 52,000 people over 30 years that “Overall, runners had a 19 percent lower death risk than non-runners. However, the health benefits of exercise seemed to diminish among people who ran more than 20 miles a week, more than six days a week, or faster than eight miles an hour.”(Active). This is a very strong demonstration that too much running or working out can be bad for your health and your heart. The study shows that the sweet spot for running is 5-19 miles a week, at a pace of 6-7mph over 3 or 4 sessions a week. These runners received the greatest benefit and least repercussions from their running.
Your body is good at burning stress and fat that fuels you for your workout, but with this comes a price. Like burning wood, burning fat and sugar creates a “smoke” inside of your body. This smoke can build up and cling to cholesterol in your body and begin to cause problems (Active). James O’Keefe, MD, Director of Preventative Cardiology at the Saint Luke’s Mid America Heart Institute in Kansas City, has stated “Your body is designed to deal with oxidative stress that comes from exercise for the first hour, but prolonged intense exercise causes excessive oxidative stress, which basically burns through the antioxidants in your system and predisposes you to problems.”
This also doesn’t mean that your should stop working out and running altogether. Like anything else in life, exercise is best done in moderation; pushing yourself every now and then is good (Active). Personally, I feel it builds a little character and grit. Just, when you feel your workouts taking it a little too far, sometimes it’s best to call it quits.
