Diversidad en la identidad y expresión de género en Educación Física: Una revisión de la literatura (Diversity in gender identity and expression in P…
2020
La escuela constituye un espacio reproductor de la cultura heteronormativa y de los patrones, roles y normas de género; especialmente desde el área de Educación Física en la que el género suele ser un tema tenido en cuenta diariamente. No todas las personas se identifican con uno de los dos sexos establecidos socialmente: masculino o femenino, pudiéndose identificar con ambos o con ninguno de ellos. El presente artículo tiene por objeto realizar una revisión de la literatura con el objetivo de explorar el momento en el que se encuentra la temática de diversidad en la identidad y la expresión del género en la etapa de Educación Primaria y concretamente en el área de Educación Física. La revi…
Influence of muscle strength and total work on exercise-induced plasma growth hormone isoforms in women
2003
The purpose of this investigation was to determine the influence of physical strength and the ability to do more total work on human growth hormone (GH) variants to a heavy resistance exercise protocol in untrained women. From a distribution of 100 healthy, untrained women, the strongest 10 women (S) and the weakest 10 women (W) were compared for GH responses pre- and post an acute heavy resistance exercise test (AHRET, 6 sets of 10 RM squats, 2 minutes rest between sets). Blood samples were obtained pre-exercise and immediately post-exercise and subsequently analysed in total as well as fractionated by Sephacryl S-100R column chromatography into three molecular weight size classes: fractio…
Distributed and Lumped Parameter Models for the Characterization of High Throughput Bioreactors
2016
Next generation bioreactors are being developed to generate multiple human cell-based tissue analogs within the same fluidic system, to better recapitulate the complexity and interconnection of human physiology. The effective development of these devices requires a solid understanding of their interconnected fluidics, to predict the transport of nutrients and waste through the constructs and improve the design accordingly. In this work, we focus on a specific model of bioreactor, with multiple input/outputs, aimed at gen- erating osteochondral constructs, i.e., a biphasic construct in which one side is cartilagi- nous in nature, while the other is osseous. We next develop a general computat…
Percepción del alumnado sobre el uso del método AICLE en Educación Física: estudio de caso (Students’ perception of the use of CLIL method in Physica…
2017
El Aprendizaje Integrado de Contenidos y Lengua Extranjera (AICLE) está siendo cada vez más extendido e investigado en el panorama educativo español. Dada la importancia de la motivación y la predisposición del alumnado para que el proceso de enseñanza-aprendizaje sea efectivo, este estudio de caso analiza la percepción de un grupo de secundaria durante la aplicación del método AICLE en la asignatura de Educación Física. Se optó por un enfoque metodológico cualitativo apoyado en la triangulación de diarios de reflexión del alumnado, registro anecdótico del profesor-investigador y un focus group. Los resultados afianzan el actual estado de la cuestión, desvelando cinco categorías sobre las q…
Beneficios y barreras identificadas por las presas que practican actividad física: Una revisión cualitativa de la literatura (Benefits and barriers i…
2017
El objetivo de esta revisión fue identificar los beneficios y las barreras que perciben las mujeres encarceladas durante la práctica de actividades físico-deportivas. La búsqueda se realizó partiendo de tres áreas –actividades físico-deportivas, prisión y mujer– la cual finalizó con 33 estudios de los cuales se seleccionaron 27, que analizaban los beneficios y/o las barreras de las presas, mediante un análisis de contenido. Los datos muestran cómo la práctica física les resulta beneficiosa tanto para su salud mental y física, como para sobrellevar y resistir la condena. A la vez, ciertos estudios revisados apuntan que las actividades físico-deportivas pueden ser beneficiosas para la futura …
Participation and performance trends in 'Ultraman Hawaii' from 1983 to 2012
2013
Abstract Background Participation and performance trends have been investigated in a single stage Ironman triathlon such as the ‘Ironman Hawaii,’ but not for a multi-stage ultra-triathlon such as the ‘Ultraman Hawaii’ covering a total distance of 515 km. The aims of this study were to analyze (1) changes in participation and performance, (2) sex-related differences in overall and split time performances, and (3) the age of peak performance in Ultraman Hawaii. Methods Age and race times including split times for 98 women and 570 men who successfully finished Ultraman Hawaii (day 1 with 10-km swimming and 145-km cycling, day 2 with 276-km cycling, and day 3 with 84-km running) between 1983 an…
Sex difference in Double Iron ultra-triathlon performance
2013
Abstract Background The present study examined the sex difference in swimming (7.8 km), cycling (360 km), running (84 km), and overall race times for Double Iron ultra-triathletes. Methods Sex differences in split times and overall race times of 1,591 men and 155 women finishing a Double Iron ultra-triathlon between 1985 and 2012 were analyzed. Results The annual number of finishes increased linearly for women and exponentially for men. Men achieved race times of 1,716 ± 243 min compared to 1,834 ± 261 min for women and were 118 ± 18 min (6.9%) faster (p < 0.01). Men finished swimming within 156 ± 63 min compared to women with 163 ± 31 min and were 8 ± 32 min (5.1 ± 5.0%) faster (p < …
Sex difference in race performance and age of peak performance in the Ironman Triathlon World Championship from 1983 to 2012
2012
Abstract Background The fastest Ironman race times in ‘Ironman Hawaii’ were achieved in very recent years. This study investigated the change in sex difference in both race performance and the age of peak performance across years in the top ten athletes for split disciplines and overall race time in the ‘Ironman Hawaii’ between 1983 and 2012. Methods Changes in split times, overall race times, and age of athletes across years for the top ten overall and the fastest swimmers, cyclists, and runners were investigated using regression analyses and analyses of variance. Results Between 1983 and 2012, the overall top ten men and women finishers improved their swimming (only men), cycling, running…
A Comparison of Anthropometric and Training Characteristics between Female and Male Half-Marathoners and the Relationship to Race Time.
2013
Purpose Lower limb skin-fold thicknesses have been differentially associated with sex in elite runners. Front thigh and medial calf skin-fold appear to be related to 1,500m and 10,000m time in men but 400m time in women. The aim of the present study was to compare anthropometric and training characteristics in recreational female and male half-marathoners. Methods The association between both anthropometry and training characteristics and race time was investigated in 83 female and 147 male recreational half marathoners using bi- and multi-variate analyses. Results In men, body fat percentage (β=0.6), running speed during training (β=-3.7), and body mass index (β=1.9) were related to half-m…
