[Serum and whole blood concentrations of fat and water soluble vitamins in normal persons and athletes].
Water-and fat-soluble vitamins have a key function in many metabolic processes and are of special importance for athletes. The water-soluble vitamins thiamine, riboflavin and pyridoxine and the fat-soluble vitamins beta-carotene, retinol and alpha-tocopherol were determined by High-Pressure-Liquid-Chromatography (HPLC). The mean serum values in non athletes (ng/ml) were for thiamine 9.23 +/- 3.62, riboflavin 6.17 +/- 2.46 and pyridoxine 12.41 +/- 4.59; the blood values for thiamine 20.12 +/- 7.58, riboflavin 13.43 +/- 3.97 and pyridoxine 18.75 +/- 6.66. The mean values of the fat-soluble vitamins were for beta-carotene 3.76 +/- 252 micrograms/l, retinol 598 +/- 141 micrograms/l and alpha-tocopherol 12.6 +/- 2.9 mg/l. The values of athletes (of different sport disciplines) for the water-soluble vitamins were much higher compared to the values found in non-athletes whereas the values for the fat-soluble vitamins were not much different.
