本研究的目的是评估比赛后血乳酸值的意义以及血乳酸-游泳速度与游泳成绩的关系。本文收集了203名意大利顶级游泳运动员（男116名，女87名）在25米游泳池比赛结束时的耳部血液样本（N = 421）。所有乳酸值的分布在雄性和雌性之间存在差异。最低的乳酸值出现在长距离游泳者（1500米）和长距离游泳者（800米）中。在参加自由泳项目的游泳运动员中，在200、400和1500米，在400和800米，男性和女性中，观察到v - 4mm （4 mmol/l血乳酸值时的游泳速度）与比赛速度之间的关系。通过个体血乳酸-游泳速度关系评估的比赛乳酸值对应的预测速度与实际比赛速度高度相关。结果表明，在游泳者血乳酸值是一个有用的指示个人资质。
The purposes of this study were to evaluate the significance of blood lactate values after competitions and the blood lactate-swimming speed relationship to swimming performances. Auricular blood samples (N = 421) were collected in 203 top level Italian swimmers (116 males and 87 females) at the end of competitions performed in a 25 m swimming pool. The distribution of all lactate values differed between males and females. The lowest lactate values occurred in swimmers performing the longest distances both in males (1500 m) and females (800 m). In swimmers performing freestyle events a relationship between V-4 mM (swimming speed at 4 mmol/l blood lactate value) and competition velocities was observed, in males, at 200, 400 and 1500 m and, in females, at 400 and 800 m. The predicted velocity corresponding to the competition lactate value assessed by the individual blood lactate-swimming speed relationship was found to be highly related to the actual competition velocity. Results suggest that blood lactate values in swimmers are a useful indication of individual aptitudes.
