Introduction: physical exercise can induce responses in bone tissue, such as the elevation of biochemical markers concentrations metabolism (such as ostecalcina and alkaline phosphatase), both secreted by osteoblasts in the formation and calcification of bone matrix process. In a study supported by FAPESP (Process: 2013/06963-5), after cohort of 09 months involving regional, state and national level athletes from various sports (volleyball, football, judo, karate and swimming), it became clear that there less gain in bone mineral density swimmers. It is necessary to consider that during the great bodily transformations adolescence happen, which affect many of the above factors described as decisive in the effects of exercise on bone tissue. In this sense, today, Allometric models are applied in order to control such body modifications and thus show the real effects of exercise, whether in health promotion or performance. But today we can not clearly say whether the osteogenic potential effect of exercise can be enhanced or minimized when such adjustments are made. Thus, the identification of this phenomenon is fundamental in our master's research, as well as to the area of knowledge in question. Objectives: To identify through allometric models the weight of the body changes related to adolescence in the complex interaction between sports practice high intensity, inflammation, biological maturation and bone growth. This knowledge will be of paramount importance for a better understanding of the phenomena addressed in the Master's purse. (AU)
