Creatine supplementation has been shown by several authors to improve physical performance in very high intensity, intermittent, exercises. The effect on performance, as well as in plasma creatine and lactate concentrations has been studied in a group of twelve sprinters of national class when running a distance of 150 m on two occasions, before and after creatine (or placebo) supplementation for the previous three days. The most important differences in the biochemical parameters analyzed have been in plasma creatinine concentration, which increased substantially both before and after the race in the group that had received a daily supplement of 25 grams of creatine monohydrate for the previous three days. Creatine supplementation, therefore, did not improve physical performance, in the conditions, when running a 150 m distance.
几位作者已证明，补充肌酸可改善极高强度间歇性运动中的身体表现。在一组12名国家级短跑运动员中，研究了在补充肌酸（或安慰剂）三天前后两次进行150米跑步时，补充肌酸对运动表现以及血浆肌酸和乳酸浓度的影响。在所分析的生化参数中，最重要的差异在于血浆肌酐浓度，在前三天每天补充25克一水肌酸的组中，比赛前后该浓度均大幅增加。因此，在这种条件下进行150米跑步时，补充肌酸并不能改善身体表现。
