Distúrbios nutricionais em atletas femininas e suas inter-relações Nutrition disorders in female athletes and their interrelationships

Pesquisas indicam que é elevada a prevalência de distúrbios alimentares em atletas femininas jovens envolvidas em esportes que preconizam a magreza e o baixo peso corporal, tais como ginástica olímpica e corridas de longa distância. A fim de compreender a etiologia destes problemas, esta revisão apresenta os principais distúrbios nutricionais encontrados em atletas femininas, incluindo definições, critérios para diagnóstico, fatores de risco, presença de desordens inter-relacionadas - anemia, irregularidades menstruais e desmineralização óssea e suas conseqüências sobre a saúde e rendimento atlético. É fundamental ressaltar a importância da nutrição no desempenho físico. A presença de um baixo peso corporal e um consumo energético severamente restrito é o principal fator de risco para o desenvolvimento de tais distúrbios. Como as atletas e seus treinadores não apresentam adequados conhecimentos sobre nutrição, é necessária uma orientação nutricional individualizada, de forma a evitar o desenvolvimento destas alterações.<br>Researches have indicated that the prevalence of nutrition disorders is high among young female athletes engaged in sports that emphasize the importance of leanness and low body weight, such as olympic gymnastics and distance running. In order to understand the etiology of these problems, this review presents the main nutrition disorders in female athletes, including definitions, diagnostic criteria, risk factors, presence of interrelated disorders (anemia, menstrual irregularities and failure of bone mineralization) and their consequences on health and athletic performance. It is fundamental to point out the importance of nutrition on physical performance. The presence of a low body weight and a very restricted energy intake is the principal risk factor for the development of nutritional disturbances. The athletes and their coaches do not have an apropriate knowledge about nutrition, so it is necessary an individualized nutritional orientation to avoid the development of these disturbances

The James Webb Space Telescope Mission

Twenty-six years ago a small committee report, building on earlier studies, expounded a compelling and poetic vision for the future of astronomy, calling for an infrared-optimized space telescope with an aperture of at least 4 m. With the support of their governments in the US, Europe, and Canada, 20,000 people realized that vision as the 6.5 m James Webb Space Telescope. A generation of astronomers will celebrate their accomplishments for the life of the mission, potentially as long as 20 yr, and beyond. This report and the scientific discoveries that follow are extended thank-you notes to the 20,000 team members. The telescope is working perfectly, with much better image quality than expected. In this and accompanying papers, we give a brief history, describe the observatory, outline its objectives and current observing program, and discuss the inventions and people who made it possible. We cite detailed reports on the design and the measured performance on orbit. © 2023. The Author(s). Published by IOP Publishing Ltd on behalf of the Astronomical Society of the Pacific (ASP).
