Abstract des Autors
We studied the nutritional and hematologic status of 22 professional ballet dancers (10 men, 12 women, mean age 25), from American Ballet Theatre by analyzing daily dietary intake and laboratory data including blood vitamin assays. The dancers had low percent body fat. Daily calorie intake was 2.967 + /- 667 kcal for men and 1,673 +/- 450 kcal for women. Carbohydrate consumption (38 of the total daily calorie intake for men and 50 for women) was too low for efficient energy use. Hemoglobin and red cell indexes were normal, but serum ferritin was below normal in eight women and three men. Serum chemistry values were normal. Blood vitamin assays were normal in all dancers, reflecting widespread use of vitamin supplements. By sports medicine standards, the dancers low calorie diets were suboptimal for strenuous physical exercise. Verf.-Referat
