We performed dietary guidances for 15 male elite athletes(23±3 years of age)participating a training program for vigorous endurance run.Nutrient allowances for the athletes were determined by the guidelines of Japanese Dietary Allowances(5 th ed.), considering their physical activities at the highest level IV;total energy 3, 500kcal, protein 140g, lipid 100g, carbohydrate 510g, calcium 1, 500mg, iron 25mg, vitamin A 8, 000IU, thiamine 4.0mg, riboflabin 5.0mg and vitamin C 200mg per day.We also developed food group allowances for the athletes based on their nutrient allowances and current young-aged Japanese dietary styles;cereals 400g, potatoes and starches 60g, sugars 20g fats and oils 30g, pulses 120g, meats 150g, fishes and shellfishes 150g, eggs 80g, milks 600g, green and yellow vegetables 300g, the other vegetables 350g, fruits 400g and algae 20g per day.For the experimental period of 45 days, daily diets adjusted to approximate 120% of the dietary allowances were served to the athletes who were free taking snacks and drinks.Dietary guidances for the athletes were assessed by monitors of their dietary intakes, physical constitution and clinical examinations in blood.Means of the dietary intakes of the athletes were 96〜99% of the dietary allowances, determined by a nutritional survey with the 24 hrs recall method.There were less changes in the physical constitution of the athletes before, during and after the experimental period;body weight 57±2 kg and body fat 8.8±2.4%.Values of the clinical marks in the blood of the athletes were maintained normally for a half year including the experimental period;red blood cells 507±9×104 cells/mm3, hemoglobin 15±0.4g/dl and hematocrit 46.6±0.7%.It is concluded that suitable nutritional guidances and managements for young-aged male vigorous endurance runners lead good in their health and physical maintenances, which may have important consequences for their physical developments as elite athletes.
