流线是竞技游泳起跳和转身的基本姿势，在许多阻力研究中都有应用。然而，在这些研究中存在着各种各样的理论解释，导致了各种各样的和可疑的结论。本研究的目的是通过荟萃分析确定流线体位的表现水平差异。速度快的游泳者的阻力系数（C-d）明显低于速度慢的游泳者，(M =。57, z = 4.30, p <。001, se =。13, 95% CI = 0.32 - 0.82)，因此，更有效的流线体位。结果支持在被动阻力研究中考虑所有相关变量，并使用Cd来区分游泳中的表现水平。
The streamline is a basic position for competitive swimming starts and turns and has been used in many studies on resistive forces. However, there is a wide variety of theoretical interpretations in these studies, leading to diverse and questionable conclusions. The purpose of this study was to determine performance level differences in the streamline position using a meta-analysis. Faster swimmers had a significantly lower coefficient of drag (C-d) than slower swimmers, (M =. 57, z = 4.30, p < . 001, SE =. 13, 95 % CI =.32-.82) and, therefore, a more effective streamline position. The results support considering all the related variables in a study of passive drag and using the Cd to discriminate between performance levels in swimming.
