Several studies have been done in regards to exercise and bone degeneration. One such study tested a group of qualified women with osteoporosis, and divided them into two separate groups, one being the control the other being the experimental group. They had x-rays done before and after the experiment to quantify the findings. The experimental group participated in daily walking for 30 minutes, and other low force, weight bearing exercise throughout the week. They continued this for approximately 2 years. The results were small but did show a slowing in bone degeneration. In the spine .85% less bone loss was noted, as well as 1.03% less bone loss in the femur. These results proved that exercise programs that included different types of training for 2 years were very beneficial at least in the short term. It does appear that it is important to train not only muscularly but cardiovascular as well. With exercise it not only will slow bone degeneration, but increase muscle strength, flexibility, and improve posture and balance.
