While we usually talk positive things in the exercise, it also be fair and emphasize the negative aspects of the practice over the year. Everything in excess is bad, and physical activity is also on the list, in fact, recent research has stressed about it.

From the University of California, San Francisco, Dr. Christoph Stehling has conducted an investigation which has been proposed to measure the effects of excessive exercise on the body, proving that this can cause arthritis.

She worked with people aged between 45 and 50 years who were followed for physical activity, and then underwent magnetic resonance to discern the health of your bones. The findings showed that participants who performed vigorous exercise had a greater damage in the knee and were at risk of developing arthritis.

While usually people with problems in the knees and joints are overweight, these participants had a healthy weight, and the only apparent cause of his injury was bone-joint exercise.

Well, just not worth an excuse for lazy people. Instead of high-impact exercises like running or basketball, you can always perform low-impact sports such as cycling or swimming, for example.
