This study is aimed at determining the content of water soluble vitamins in amateur sportsmen before and after the use of reduction diet. Twenty adult male amateur sportsmen aged between 20 and 43 qualified for this study. The participants adhered to individually adjusted reduction diets for 3 months. Diet supplements were excluded from the diet during that time. Vitamins were analyzed before and after the reduction diet using HPLC. The following vitamins were analyzed: B1, B2, B3, PP, B5, B6, B7, B9, B12 and vitamin C. Statistically significant increase of riboflavin in blood plasma (p=0.0254) and statistically significant (p=0.048) decrease in the concentration of niacin was found when compared to the period before the diet. Appropriate level of riboflavin can be obtained by the consumption of proper amount of diary in the diet. Supplementation with PP is advised and, in case of improper diet, the supplementation of B1, B7 and B12 may also be considered.
本研究旨在测定成年男性业余运动员在采用减脂饮食前后水溶性维生素的含量。20名年龄在20至43岁之间的成年男性业余运动员符合本研究要求。参与者遵循个性化调整的减脂饮食3个月。在此期间，饮食中不包含膳食补充剂。使用高效液相色谱法（HPLC）分析减脂饮食前后的维生素。分析的维生素如下：维生素B1、B2、B3、PP、B5、B6、B7、B9、B12和维生素C。与饮食前相比，血浆中核黄素出现具有统计学意义的增加（p = 0.0254），烟酸浓度出现具有统计学意义的降低（p = 0.048）。通过在饮食中摄入适量的乳制品可获得适当水平的核黄素。建议补充PP，在饮食不当的情况下，也可考虑补充B1、B7和B12。
