Iron is necessary for adequate deliver oxygen to the tissues since it is an essential component of the haemoglobin. However, iron deficiency remains a common problem among athletes, particularly for women experiencing the menstrual bleeding every month. The iron losses through menstrual blood loss during the early follicular phase (or menses) and an inadequate dietary intake of iron are two important factors contributing to this disease. Furthermore, the large hormonal changes that women experience ...

Heritability is a statistical population parameter which allows us to know the proportion of phenotypic variation in a population that is attributable to genetic variation between individuals. It always refers to a specific phenotypic trait in a given population at a given time. Because of the importance heritability has to the research in genetics – including the one related to fitness and physical activity – and due to the permanent confusion the interpretation of this parameter generates, our purpose ...

Serum ferritin has been proposed as a predictor of hepcidin concentrations in response to exercise. However, this fact has not been studied in physically-active women. Therefore, the main objective of this study was to analyse the hepcidin response at different ferritin status before and after running exercise in physically active females. Fifteen eumenorrheic women performed a 40-min running protocol at 75% of VO2peak speed in different menstrual cycle phases (early-follicular phase, mid-follicular ...

El objetivo de la presente investigación fue analizar el poder predictivo de la motivación intrínseca y la autoeficacia para mantenerse activo sobre el bienestar psicológico en estudiantes universitarios mexicanos físicamente activos. La muestra de este estudio predictivo transversal estuvo conformada por 539 estudiantes universitarios físicamente activos, de ambos sexos (Hombres = 34%, mujeres = 66%) y con edades comprendidas entre los 17 y 47 años (M = 19.8, DT = 2.88). El 84% de los universitarios reporta ...

El presente trabajo revisa los estudios que analizan los efectos agudos y cronicos del uso de ETM sobre variables asociadas al rendimiento fisico. Aunque existe controversia, la mayoria de los trabajos reportan una respuesta hipoxica aguda y mejoras de parametros cardiorrespiratorios derivados del uso de ETM, ademas de ser, en terminos generales, ...

Varios autores afirman que en los ultimos anos se ha ido conformando un campo de saber especifico de la Educacion Fisica (EF). Mi percepcion es la contraria. Considero que la EF se aleja cada vez mas de la anhelada unidad y autonomia; y no apenas en el campo teorico, sino tambien en el de la intervencion y formacion profesional. Sostengo que esto no representa ningun desmerito ni problema. Partiendo de la conviccion que la EF es un area profesional orientada a la intervencion, sugiero dejar de “inventar” ...

In soccer, sprinting speed and vertical jump are critical skills to achieve high performance. Controversy exists about which type of training is most appropriate to improve these skills in youth players with no previous experience in programmed strength training. The aim of this study was to evaluate the efficacy and efficiency of a 16-week programme of resistance (weight) and plyometric training on sprinting and vertical and horizontal jumping in male youth soccer players. The study involved 18 ...

A los diez mejores corredores de fondo varones (ranking Confederacion Atletica del Uruguay - CAU) se les midio la fuerza maxima de miembros inferiores y superiores, la flexibilidad de la cadera, la frecuencia cardiaca basal (FCB), el tiempo en 100, 300 y 2000 m, la composicion corporal y el somatotipo. Los tests de fuerza maxima, ...

The present study points out some important limitations of traditional observational studies, with the aim of proposing a systemic-complex, tactical-strategic observational model in soccer (SOTEF). Based on original concepts from systemic and complexity sciences, we developed SOTEF, which we think will be useful both for coaches in their professional practice and for researchers in the study of soccer and other team sports. If so, we will also be helping to reduce the gap that currently separates ...

Objective: The association between sex hormones and bone mineral density (BMD) has been studied in sedentary women, whereas only few studies have evaluated trained females. Therefore, the aim of this study was to assess the influence of sex hormones on BMD in well-trained females with different hormonal profiles: eumenorrheic females, oral contraceptive (OC) users and postmenopausal women. The secondary purpose was to determine if maximal oxygen consumption (V̇ O2max) or maximal back squat strength ( ...
