The purpose of the study was to identify the stroking characteristics such as rate and length used by male swimmers of differing skill and to analyze the variations of velocity, stroke rate, and stroke length during the course of the race. The performance of 442 male subjects including 40 swimmers competing at an international 100-m freestyle event was videotaped and later analyzed to measure velocity, stroke rate, and stroke length on each lap of the race. Stroke length seemed to be the best predictor of swimming velocity. Different levels of performance could be discriminated by the variations of velocity, stroke rate, and especially stroke length, throughout the race. Besides higher values for velocity, stroke rate, and stroke length, the best swimmers were characterized by the capacity to maintain these parameters constant throughout the course of the race. Such results could be used by coaches to assess technique and training for certain racing strategies.
该研究的目的是确定不同技能水平的男性游泳运动员的划水特征，如划水频率和划水长度，并分析比赛过程中速度、划水频率和划水长度的变化。对包括40名参加国际100米自由泳比赛的游泳运动员在内的442名男性受试者的表现进行了录像，随后进行分析，以测量比赛每一圈的速度、划水频率和划水长度。划水长度似乎是游泳速度的最佳预测指标。在整个比赛过程中，不同的表现水平可以通过速度、划水频率，尤其是划水长度的变化来区分。除了速度、划水频率和划水长度的值更高外，最优秀的游泳运动员的特点是能够在比赛过程中保持这些参数不变。教练可以利用这些结果来评估技术和针对特定比赛策略的训练。
