Abstract des Autors
We performed dietary guidances for 15 male elite athletes (23+/-3 years of age) participating in a training program for vigorous endurance run. Nutrient allowances for the athletes were determined by the guidelines of Japanese Dietary Allowances (5th ed.), considering their physical activities at the highest level IV; total energy 3,500 kcal, protein 140 g, lipid 100 g, carbohydrate 510 g, calcium 1,500 mg, iron 25 mg, vitamin A 8,00 IU, thiamine 4.0 mg, riboflabin 5.0 mg and vitamin C 200 mg per day. We also developed food group allowances for the athletes based on their nutrient allowances and current young-aged Japanese dietary styles; cereals 400 g, potatoes and starches 60 g, sugars 20 g fats and oils 30 g, pulses 120 g, meats 150 g, fishes and shellfishes 150 g, eggs 80 g, milks 600 g, green and yellow vegetables 300 g, the other vegetables 350 g, fruits 400 g and algae 20 g 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 x 104 cells/mm**3, hemoglobin 15+/-0.4 g/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 development as elite athletes.
