Ninety-six high-performance athletes of various disciplines were available for this investigation. All athletes had many years of training and competition experience. The pantothenic acid contents in the blood were determined by means of microbiological measurements. In addition to the pantothenic acid level at rest, measurements were made resp. physical exertion in 14 marathon runners and nine body builders. Blood was collected for determination of pantothenic acid before (a), after (b) and 2 h after exercise. Compared to the reference values for untrained persons (1.34 +/- 0.13 nmol/mL), the marathon runners with 0.76 (0.31-0.94) nmol/mL and soccer players with 1.19 (0.37-2.64) nmol/mL were below the reference values. According to relative frequencies, more than 30% of all athletes were below the lower limit (< 1.20 nmol/mL). The values in body builders/racing cyclists differed significantly from those in marathon racers (p < 0.001), which is presumably due to unallowed supplementation. During exercise, there was a significant increase in the pantothenic acid level in marathon runners (p < 0.01).
本研究选取了96名不同项目的高水平运动员。所有运动员均有多年的训练和比赛经验。通过微生物测量法测定血液中的泛酸含量。除了测定静息状态下的泛酸水平外，还对14名马拉松运动员和9名健美运动员在运动后的泛酸水平进行了测量。在运动前（a）、运动后（b）以及运动后2小时采集血液以测定泛酸含量。与未受过训练者的参考值（1.34±0.13纳摩尔/毫升）相比，马拉松运动员的泛酸含量为0.76（0.31 - 0.94）纳摩尔/毫升，足球运动员为1.19（0.37 - 2.64）纳摩尔/毫升，均低于参考值。根据相对频率，超过30%的运动员泛酸含量低于下限（<1.20纳摩尔/毫升）。健美运动员/场地自行车运动员的泛酸含量值与马拉松运动员的差异显著（p<0.001），这可能是由于违规补充所致。在运动过程中，马拉松运动员的泛酸水平显著升高（p<0.01）。
