The purpose of this study was to determine differences in bone mineral density (BMD) among adolescent female tennis players (TPs) and nontennis players (NTPs) and to assess body composition as a predictor variable of BMD. Nineteen female TPs and 19 female NTPs, ages 14 to 18 years, participated in this study. Lumbar spine, total hip, femoral neck, forearms BMD, and body composition were assessed using dual-energy X-ray absorptiometry (DXA). Lumbar spine and total hip BMD measurements for TP were greater than NTP. However, these differences were not statistically significant (P = 0.37 and 0.12, resp.). TP had significantly greater femoral neck BMD than NTPs (P = 0.02). This difference might play an important role in preventing osteoporosis and decreasing the risk of fractures at the hip later in life.
本研究的目的是确定青春期女性网球运动员（TPs）和非网球运动员（NTPs）之间骨矿物质密度（BMD）的差异，并评估身体成分作为BMD的预测变量。19名年龄在14至18岁的女性TPs和19名女性NTPs参与了本研究。使用双能X线吸收法（DXA）评估腰椎、全髋、股骨颈、前臂的BMD以及身体成分。TPs的腰椎和全髋BMD测量值高于NTPs。然而，这些差异无统计学意义（分别为P = 0.37和0.12）。TPs的股骨颈BMD显著高于NTPs（P = 0.02）。这种差异可能在预防骨质疏松症和降低晚年髋部骨折风险方面发挥重要作用。
