Sažetak / Summary   PUNI TEKST / FULL TEXT (.pdf)

A bone is a dynamic tissue that remodels during the entire life span. Remodeling includes two continuous processes, namely forming and resorbing. These processes are continuous and occur as a response to a weight-bearing physical activity. Remodeling processes are  very important for maintenace of skeletal homeostasis.
Recent evidence shows that growing bone is more responsive to mechanical loading and physical activity then mature bone. This indicates that regular exercise early in life may be an important factor in the prevention of osteoporosis later on.
Further, high and medium level of weight-bearing physical activity (walking, ball games, dancing, aerobics, jogging, skiing, martial art, gymnastics, strength training and racket sports) correlates positively with the high bone mass in adults. For elderly even an hour of slow walking (low level of activity) can have a beneficial effect on the bone quality.
Research done on athletes shows that they have higher bone mass than non-athletes and that the bone density increases during the periods of intensive training. 
Weight-bearing physical activity is essential for normal development and maintenance of healthy skeleton. In humans, physical activity appears to play an important role in maximizing bone mass during childhood and the early adult years, maintaining bone mass through the fifth decade, attenuating bone loss with aging, and reducing falls and fractures in the elderly.
