AMENORREA EN ATLETAS PDF

Una atleta puede tener uno, dos o los tres componentes de la triada. Consecuentemente, sus ciclos menstruales se pueden volver sumamente irregulares y hasta puede llegar a dejar de menstruar. Algunas chicas que hacen mucho deporte y con mucha intensidad es posible que no lleguen a tener su primer periodo menstrual por lo mucho que entrenan. A muchas chicas les preocupa el volumen y la forma de sus cuerpos. Por lo tanto, el peso corporal es una parte importante del programa de entrenamiento, y este factor expone a las chicas que los practican al riesgo de desarrollar alteraciones en la conducta alimentara. La verdad es que el mero hecho de perder peso no suele mejorar el rendimiento deportivo.

The purpose of this review is to focus the exercise as a modulator of human reproduction and to summarize and integrate current data concerning the hypothalamus-pituitary-gonadal axis in exercising women. The prevalence of menstrual dysfunctions, as the luteal phase deficiency, oligomenorrhea, amenorrhea and menarcheal delay are greater among athletes than in the general population.

Many factors undergo changes during the course of an athletic training program and any or all of these may contribute to disturbances in menstrual cyclicity. A number of risk factors have been identified as predisposing women to the development of menstrual irregularities, such as low body weight, body fat and hypoestrogenic status. Hypoestrogenism may affect peak bone mass in the puberty and lead to irreversible premature bone loss.

La triada de la atleta

Introduction: The female athlete triad FAT is a serious health-related problem that threatens women who exercise. This condition is an interrelated multifactorial syndrome which includes low energy availability, menstrual cycle disturbances and decreased bone mineral density. Objective: To review the major components of the FAT and their relationships, as well as strategies for diagnosis and treatment. Results: Interrelationship between components of the FAT may result in clinical manifestations, including eating disorders, amenorrhea and osteoporosis. Clinical conditions are not always exhibited simultaneously. Prevention is important to minimize complications.
