Learning about the influence of sports on the teenagers’bone mineral density and bone metabolism and providing more reliable theories for reducing the possibility of suffering from the Osteoporosis Disease by measuring and comparing indexes relative to the bone mineral density and bone metabolism of two groups of teenagers. One group of teenagers do regular exercise and others do a little. The method: Based on the principal of randomization, choosing forty students from universities in Beijing,twenty of whom are major in PE and do regular exercise but others are not PE majors and just do a little exercise, to measure their bone mineral content, bone mineral density and projection area of the different parts in their waists and hips, and also their biochemical indexes reflecting the bone metabolism,such as T, ALP, U-HOP, U-Ca, U-Cr and so on. The result: The bone mineral content and bone density of the teenagers who do regular exercise are higher than those of students who are not in PE major, and especially the T of the former is distinctly higher than that of the latter; Although other biochemical measurements of the two groups of teenagers are low and without distinct differences, the ALP of the teenagers who do regular exercise is higher than that of ones who do a little. The conclusion: Doing regular exercise makes a positive effect on teenagers’bone health because that is helpful to increase their bone mineral density and bone mineral content by influencing their bone metabolism. So doing regular exercise can make a solid healthy bone foundation for teenagers and reduce the possibility of they suffering from the Osteoporosis Disease as they grow older.
