Vitamin B1, B2, B6, C, A, and E status was assessed by combining determination of dietary intake with biochemical indices in 55 young male athletes. When compared with 20 matched sedentary controls, a similar number of individuals with biochemical deficiency was found in both groups for vitamins B1, B6, and E despite a higher mean dietary intake of these three vitamins in young athletes. Markedly reduced levels of pyridoxal 5'-phosphate, the biologically active form of the vitamin B6 compounds, were found in both populations. Supplementation administered for one month improved the vitamin status of the control subjects but not entirely those of the young athletes.
通过结合饮食摄入量测定和生化指标，对55名年轻男性运动员的维生素B1、B2、B6、C、A和E状况进行了评估。与20名匹配的久坐对照组相比，尽管年轻运动员这三种维生素的平均饮食摄入量较高，但两组中维生素B1、B6和E出现生化缺乏的个体数量相似。在这两个人群中均发现维生素B6化合物的生物活性形式——5'-磷酸吡哆醛的水平显著降低。补充一个月后，对照组受试者的维生素状况得到改善，但年轻运动员的维生素状况并未完全改善。
