Exercises like the two blades

Exercise of maintaining bone

The fact of supporting your body weight and the burden of mechanical traction that occurs with muscle contraction during exercise stimulates the bone remodeling process. About a quarter of total minerals deposited in the bone is obtained during the approximately 2 year period of puberty, and about 95% of our bone mass is reached at the end of adolescence.

Scientific studies suggest that the practice of sports and activities before and during puberty appears to be more effective in building stronger bones. Activities involving jumping are particularly useful. Therefore, a key strategy to ensure long life to the bones, and these are strong, is to maximize bone mineral density and rapid growth during adolescence by encouraging regular participation in a variety of physical activities and sports.

Peak bone mass usually occurs during the third decade of life. Then and for a time, the rate of bone absorption and formation is quite stable. But at 40 years start resorption exceeding formation rate, and begins to experience a net loss of bone.

Exercise: a double-edged sword

So the good news is that all you are doing exercise can stimulate the building of strong bones. The bad news is that some athletes have low bone mass or osteopenia sports. And unfortunately, this is all too commonly diagnosed in women athletes. As a result, are at high risk of stress fractures during exercise. A stress fracture is a partial or complete break in the bone. It is caused by the inability of bone to withstand repeated stress but not violent. Stress fractures occur due to microscopic damage accumulates in bone, and when these are not adequately repaired by the remodeling process previously discussed. An increased load on the bones can cause a stress fracture. Also guilty are also other factors that interfere with the repair and remodeling of bone, or those that reduce bone strength.

The question is, if exercise is a positive stimulus for stronger bones, why do some athletes have low bone mineral density and weak bones?
