Influence of physical activity to bone metabolism.
Bone remodeling is a lifetime process. Peak bone mass is achieved in the twenties, and that  value is very important for skeleton  health in older years of life. Modern life style with its diet poor in  nutrients, and very low intensity of physical activity negatively  influences health in general, and bone health as well. Bones are  adapting to changes in load, so applying mechanical strain to bones results in greater bone mass and hardness.  That makes  physical activity important in maintaining skeleton health. Numerous  studies confirm good influence of regular exercising to bone health, and connection of physical activity in youth to  better bone  density in older age. To activate bone remodeling mechanisms, it  is necessary to apply mechanical strain to bones by exercise. Considering global problem of bone loss and osteoporosis new  ways  of activating young people to practice sports and active stile of life  are necessary to maintain skeleton health and health in general.  This paper aims to review physiological mechanisms of bone remodeling that are influenced by physical exercise.
