Hepcidina: hormona reguladora del metabolismo del hierro en el deportista
Nutrition is very important to ensure proper health and optium sports performance. Thus, an objective of Nutrition will be to ensure an adequate state of body iron stores, because iron deficiency is the most common nutritional deficiency and because iron is a constituyent element of hemoglobin and myoglobin. There is a direct relationship between hemoglobin levels and VO2max, main limiting factor of endurance performance. It was recently discovered a new hormone (hepcidin), whose main effect is to act as a negative regulator of iron absorption by degrading ferroportin. The aim of this study was to analyze the studies that have studied the response of hepcidin to exercise as a requirement to give guidelines that allow to regulate hepcidin levels in athletes, preventing possible iron deficiency stores.La nutrición cobra una enorme importancia a la hora de asegurar un estado de salud y un rendimiento deportivo óptimo. Uno de los principales objetivos irå encaminado a asegurar un adecuado estado de las reservas corporales de hierro, dado que la deficiencia de hierro es la mås frecuente y a que dicho elemento forma parte constituyente de la hemoglobina y mioglobina. Existe una relación directa entre los niveles de hemoglobina y el VO2måx, principal factor limitante del rendimiento de resistencia. Recientemente se ha descubierto una nueva hormona (hepcidina), cuyo efecto principal es la de actuar como regulador negativo en la absorción del hierro, al degradar la ferroportina. El objetivo del presente estudio ha sido el de analizar los distintos trabajos que han estudiado la respuesta de la hepcidina al ejercicio como requisito para poder dar pautas que permitan regular los niveles de hepcidina en el deportista, previniendo posibles estados ferropénicos

McArdle disease: what do neurologists need to know?
McArdle disease (also known as glycogen storage disease type V) is a pure myopathy caused by an inherited deficit of myophosphorylase, the skeletal muscle isoform of the enzyme glycogen phosphorylase. The disease exhibits clinical heterogeneity, but patients typically experience exercise intolerance, that is, reversible, acute crises (early fatigue and contractures, sometimes with rhabdomyolysis and myoglobinuria) triggered by static muscle contractions (e.g. lifting weights) or dynamic exercise (e.g. climbing stairs or running). In this Review, we discuss the main features of McArdle disease, with the aim of providing neurologists with up-to-date, useful information to assist their patients. The topics covered include diagnostic tools-for example, molecular genetic diagnosis, the classic ischemic forearm test and the so-called 'second wind' phenomenon-and current therapeutic options-for example, a carbohydrate-rich diet and carbohydrate ingestion shortly before strenuous exercise, in combination with medically supervised aerobic training of low to moderate intensity.6.979 JCR (2008) Q1, 5/156 Clinical neurologyUE
