Resistive or drag forces encountered during free swimming greatly influence the swim performance of elite competitive swimmers. The benefits in understanding the factors which affect the drag encountered will enhance performance within the sport. However, the current techniques used to experimentally measure or estimate drag values are questioned for their consistency, therefore limiting investigations in these factors. This paper aims to further understand how the resistive forces in swimming are measured and calculated. All techniques outlined demonstrate both strengths and weaknesses in the overall assessment of free swimming. By reviewing all techniques in this area, the reader should be able to select which one is best depending on what researchers want to gain from the testing.
自由泳过程中遇到的阻力或曳力会极大地影响优秀竞技游泳运动员的游泳表现。了解影响所遇阻力的因素所带来的益处将提升这项运动的成绩。然而，目前用于实验测量或估算阻力值的技术因其一致性受到质疑，因此限制了对这些因素的研究。本文旨在进一步了解游泳中的阻力是如何测量和计算的。所概述的所有技术在自由泳的整体评估中都显示出优点和缺点。通过回顾该领域的所有技术，读者应该能够根据研究人员希望从测试中获得的结果来选择最适合的技术。
