Young women including long-distance runners (n=5, aged 21±3 years, BMI 19±1 kg/m^2, training distance 125±0 km/week and daily energy intake 49±3 kcal/kg expressed as mean±SD, respectively), joggers(n=5.24±1 years, 20±2 kg/m^2, 22±13 kin/week and 39±5 kcal/kg) and untrained women (n=7.25±2 years, 21±1 kg/m^2 and 34±5 kcal/kg) participated in this study for evaluating blood vitamin statUS. The runners had higher intake of vitamins A (retinol), B_1, B_2, C and E than the joggers and the untrained women. Almost all subjects had fairy good blood vitamin status except B_1. Ten of the subjects (5 joggers and 5 untrained women) had unfavorable B_1 status in terms of TDP effect. There was no significant correlation between dietary intake of B_1 and TDP effect, indicating large individual variations of B_1 status in young women. The runners'group had the most favorable nutritional condition among the three group because they had been taking well-balanced diets. These results suggest that maintaining favorable vitamin status in young women needs individual dietary instruciton depending on the physical activity levels of those women.
