Determination of body composition is an essential parameter in training athletes because low fat-muscle ratio might improve physical performance in many types of sports. Since training is often conducted in the field, it is important to determine whether simple field measurements of body composition assessment correlate with laboratory measurements.
Examine the correlation of body fat content as measured using skinfold thicknesses (SF), air-displacement plethysmography (BOD POD), bioelectrical impedance analysis (BIA) and body mass index (BMI) age and gender adjusted percentiles.
Body mass as measured by SF, BOD POD, BIA, and BMI percentiles were examined in 29 elite, national team level, male and female volleyball players (age range 13 to 18) at the beginning of the training season.
Body fat percent measured by SF, BIA and BOD POD were highly positively correlated (r > 0.83). Measurements of body fat by SF, BIA and BOD POD were weakly correlated with BMI percentiles (r < 0.45).
Results suggest that BMI percentile is not a good measure for body fat in adolescent elite male and female volleyball players. SF and measurements of body composition by BIA and BOD POD are essentially interchangeable.
身体成分的测定是训练运动员的一个重要参数，因为低脂肪 - 肌肉比率可能会提高许多类型运动中的身体表现。由于训练通常在野外进行，确定身体成分评估的简单野外测量是否与实验室测量相关很重要。
研究使用皮褶厚度（SF）、空气置换体积描记法（BOD POD）、生物电阻抗分析（BIA）以及年龄和性别调整百分位数的体重指数（BMI）测量的体脂含量之间的相关性。
在训练赛季开始时，对29名精英国家队水平的男女排球运动员（年龄范围13至18岁）进行了通过SF、BOD POD、BIA和BMI百分位数测量的体重检查。
通过SF、BIA和BOD POD测量的体脂百分比高度正相关（r > 0.83）。通过SF、BIA和BOD POD进行的体脂测量与BMI百分位数弱相关（r < 0.45）。
结果表明，BMI百分位数不是青少年精英男女排球运动员体脂的良好测量指标。SF以及通过BIA和BOD POD进行的身体成分测量基本可以互换。
