PURPOSE
The study was designed to examine the effect of sports of varying skeletal loading on bone density in adolescent female athletes.
METHODS
Bone mineral densities of female swimmers, soccer players, and weight lifters were examined. Between-sport comparisons were made using a one-way analysis of covariance with age and body mass index as covariates and group bone mass density (BMD) was compared to the World Health Organization's (WHO) normative values for adult females.
RESULTS
BMD was significantly greater in the soccer group compared to the weight lifting (p = 0.025) and swimming groups (p = 0.001) with no difference between weight-lifting and swimming groups (p = 0.209). Compared to normative data from the WHO, soccer was the only sport whose participants' BMDs were significantly greater than adult norms (p = 0.003), while those of the swimmers were significantly less (p < 0.001) than adult females, and the weight lifters were not different (p = 0.103).
CONCLUSIONS
Participation in sports such as soccer or weight lifting with significant skeletal loading may enhance BMD in adolescent females.
目的
本研究旨在探讨不同骨骼负荷运动对青春期女性运动员骨密度的影响。
方法
对女性游泳运动员、足球运动员和举重运动员的骨矿物质密度进行检测。以年龄和体重指数作为协变量，采用单因素协方差分析进行运动项目间比较，并将各组骨密度（BMD）与世界卫生组织（WHO）成年女性的标准值进行比较。
结果
与举重组（p = 0.025）和游泳组（p = 0.001）相比，足球组的骨密度显著更高，而举重组和游泳组之间无差异（p = 0.209）。与WHO的标准数据相比，足球是唯一一项参与者骨密度显著高于成年标准的运动（p = 0.003），而游泳运动员的骨密度显著低于成年女性（p < 0.001），举重运动员则无差异（p = 0.103）。
结论
参与足球或举重等具有显著骨骼负荷的运动可能会提高青春期女性的骨密度。
