| Popis: | Twenty-two female teenagers engaged in elite gymnast training and 22 healthy girls of comparable age were studied with regard to nutritional intake. The mean daily intakes of most nutrients in both groups were in accordance with the Swedish Nutritional Recommendations; exceptions were iron and dietary fibre which were too low in both groups. The individual variation was large in both groups and many subjects had an intake below the nutritional recommendations. Both the gymnasts and the reference group had an energy intake significantly below the estimated energy need. The mean daily energy intake was 725 kcal less than the energy need in the gymnast group and 450 kcal less in the reference group. The clinical investigation revealed that several gymnasts had delayed menarche or irregular menstruation as well as less body fat than the reference group. Among the gymnasts, girls with a regular menstrual pattern had more body fat than those who had not started to menstruate. The higher energy expenditure of the gymnasts could partly explain their smaller amounts of body fat, late pubertal development and menstrual patterns. |
