Abstract

[automatically translated] OBJECTIVE - To assess, in the period of reaching the peak bone mass, the effects of exercise on bone mineralization in young people. MATERIALS AND METHODS - The study involved 43 male subjects, healthy, with a mean age of 25 years, divided into three groups depending on the intensity of your physical activity from age ten onwards: the first consists of 17 subjects sedentary, the second from 16 active players and third athletes from 15 subjects. Each subject underwent a bone density scan (DEXA). Measuring bone density (BMD, g / cm2) of the subjects covered: entire body (Total Body), right and left femoral neck and L2-L4 spinal tract. The benchmark was the Z-Score. RESULTS - The comparison of the values of Z-Score between sedentary and active groups showed statistical significance for the values of Z-Score in total body and lumbar L2-L4. The Z-Score in the left femoral neck and right is not significant. In comparing sedentary and athletes, as well as between active athletes and the values of Z-Score of Total Body, the L2-L4 tract and left femoral neck and right are all significant. CONCLUSIONS - In the comparison between the three groups is evident, in the sedentary, the Z-score of the lumbar spine with a lower value than the other groups, in our opinion probably due to lack of physical activity. The Z-Score of the femoral neck, in the comparison between sedentary and active, shows no statistical difference despite the two different lifestyles; probably the upright position and walking are already sufficient stimulus to the mineralization of femurs. In comparing sedentary and athletes, as well as between active and athletes, it is a statistical significance for the Z-Score of the L2-L4 lumbar spine and the femoral neck; This highlights how physical activity over the long haul and with adequate intensity stimuli greater bone mineralization, especially in the range between 10 and 25 years when you reach your peak bone mass. Having a greater peak bone mass in young people is the basis of prevention of those possible phenomena, present in adulthood, such as osteopenia or osteoporosis. is statistical significance for the Z-Score of the L2-L4 lumbar spine and the femoral neck; This highlights how physical activity over the long haul and with adequate intensity stimuli greater bone mineralization, especially in the range between 10 and 25 years when you reach your peak bone mass.
