Physical activity stimulates bone growth

Research has revealed key mechanisms by which exercise increases bone growth. This is another argument in favor of more frequent sports.

The authoritative scientific journal Cell Reports publishes the results of a study by scientists from the National Institute of Cerebral and Cardiovascular Health in Japan.

They proved that exercise affects the severity or expression of osteocrine peptide (OSTN). Bones and skeletal muscles are strengthened due to loads, which is a consequence of physical exercises. And this prevents atrophy of bones and muscles, maintaining their strength, which is extremely important for health.

The growth of long bones such as the femur and tibia is a very complex process that is controlled by genetic factors and the environment. And among the factors of the latter are physical exercises for endurance. Bones are supported by the combined balanced activity of osteoblasts and osteoclasts – the first type of cells forms bone, and the second destroys it.

Researchers observed the expression of the OSTN peptide, which is produced by osteoblasts. Laboratory mice were observed. It turned out that the expression of OSTN is expressed in such bones as the tibia, radius and ulna. The lower the level of physical exertion the mice had, the lower the expression of this peptide was.
