(1) Background: Despite plenty of evidence supporting the advantages of regular physical exercise amongst older women, it is not clear what the best methodology is to improve these parameters. Considering the growth of older population and aging process, this study analyses an 8-weeks concurrent training intervention; (2) Methods: A total of 48 older women participated in concurrent strength and aerobic exercises training intervention being used to know physical and cognitive improvements in older women through physical, physiological and vigilance tests; (3) Results: Significant differences were found in weight and body mass index (BMI) between pre-intervention and post-intervention and even better results, but non-significative, in maximum oxygen consumption (VO2max), total fat percentage and skeletal muscle mass. Additionally, we found cognitive improvements in vigilance (RT) related to executive functions. (4) Conclusions: An 8-weeks concurrent training program (strength and aerobic exercises) give another efficient possibility to obtain better physical, physiological and cognitive improvements in older women.

El presente trabajo pretende hacer una revisión de la preocupante situación actual en cuanto a la práctica de actividad física en nuestro país y el problema que nos lleva a estar por debajo de la media europea, con los consiguientes problemas de obesidad que se derivan de esto, sobre todo infantil. Analizamos los programas de intervención que se están utilizando como el plan PIOBIN (Plan Integral de Obesidad Infantil) que propuso la Junta de Andalucía, con vigencia 2007-12, basado en una estrategia a nivel nacional denominada Estrategia Naos y distintos estudios que avalan que unas motivaciones intrínsecas hacia la práctica de actividad física ayudan a crear hábitos duraderos hacia dicha práctica. También realizamos un análisis de las distintas teorías que existen sobre motivaciones, basando nuestro estudio en la Teoría de la Autodeterminación (self-determination theory) de Deci y Ryan (1985, 2000).Palabras clave: Motivaciones intrínsecas, actividad física, obesidad infantil.Abstract: This paper aims to review the current worrying situation in terms of physical activity in our country and the problem that leads us to be below the European average, with the attendant problems of obesity, particularly among children, which follow from this. We analyzed the intervention programs that are being used as PIOBIN plan (The Andalusian Plan for Childhood Obesity), effective from 2007-12, based on a national strategy called Naos Strategy and how different studies support that some intrinsic motivation toward physical activity helps to create lasting habits to the practice. We also carry out an analysis of the different Motivation theories and we base our study on the Self-determination Theory of Deci and Ryan (1985, 2000).Key words: Sport; Leisure; Mass Media; Culture.

La presente investigación pretendió analizar los efectos del uso del blog educativo (i.e. Edublog) sobre la coeducación, compromiso con esta herramienta digital, calificación e intención de ser físicamente activo en clase de educación física en educación primaria. El estudio corresponde con un diseño cuasi-experimental, usando un grupo control, a priori, no equivalente y, un grupo experimental para una muestra total de 40 estudiantes de educación primaria (50.50% chicas; Medad = 10.55, DTedad = .51). Se tomaron medidas acerca del conocimiento de equidad y calificación al final del programa de intervención, medidas sobre la implicación con el Edublog durante todo el programa, mientras que la intención de ser físicamente activo se evaluó al inicio y al final del programa. Los resultados revelaron la existencia de diferencias estadísticamente significativas en el nivel de conocimiento de equidad, implicación con el Edublog y calificación a favor del grupo experimental. No hubo diferencias estadísticamente significativas en el nivel de intención de ser físicamente activo entre ambos grupos. A modo de conclusión, el Edublog puede ser un recurso didáctico tenido en cuenta por el profesorado a la hora de mejorar las experiencias educativas del alumnado de educación primaria cuando participa en educación física.AbstractThis research aimed at examining the effects of the usage of the educational blog (or Edublog) on coeducation, commitment to this digital tool, grades and intention to be physically active in Physical Education lessons in Primary school. The study adopted a quasi-experimental design with, a priori, a non-equivalent control group and an experimental group for a total of 40 primary school students (50.50% girls; Mage = 10.55, SDage = .51). Measures on knowledge of equity and grades were taken at the end of the intervention programme, measures on a commitment to Edublog were collected throughout the programme, while the intention to be physically active were assessed at the beginning and end of the intervention. The results revealed statistically significant differences in the level of knowledge of equity, the commitment of Edublog and grades a favour of the experimental group. There was a nonsignificant difference in the level of intention to be physically active among both groups. In conclusion, Edublog can be a learning recourse to be considered by teachers in improving primary school students’ educational experiences when they participate in Physical Education.

Con este trabajo queremos poner de manifiesto otro tipo de entrenamiento distinto a las recomendaciones tradicionales que desde las organizaciones más influyentes (ACSM-American Collegue Sport Medicine, WHO-World Health Organization y AHA-American Heart Association) hacen para que el entrenamiento sea más efectivo a la luz de los últimos estudios sobre Actividad Física (AF) y salud.El entrenamiento concurrente (fuerza-resistencia) unido con un trabajo de intensidad polarizada (alta y baja) produce mejores resultados para la lucha de la obesidad que el trabajo aislado de ambas y de intensidades submáximas como se venía trabajando en los protocolos más clásicos.

Background: Motivation in athletes is a state that fluctuates due to multiple factors that can, in turn, negatively or positively influence sports performance. Objectives: The aim of this study was twofold, being, on the one hand, to analyze the motivation of soccer players of developmental age in two different contexts (training time (baseline) and the precompetitive time) depending on the category, sports success and playing position, and, on the other hand, to find relations of the motivation dimensions with the academic performance and physical characteristics of the soccer players. Methods: One hundred and forty-one under 16 (U16) soccer players were selected (age: 14.7 ± 0.5; height: 170.4 ± 7.2 cm; weight: 61.6 ± 10.0 kg). Data on academic performance, physical and socio-demographic characteristics were recorded, and in two differentiated moments, the motivation dimensions, both in training and in competition. Results: The results showed that the general motivation decreases with the competition, and in particular, the intrinsic motivation, where the precompetitive evaluation is lower than the basal, in both categories (p < 0.05). In addition, demotivation is explained by 10.2%, 19.8%, and 23.9% by fat mass, by academic performance, and by category, respectively; and the extrinsic motivation of external regulation is explained in 26.0% by the academic performance factor (p < 0.01). Conclusions: U16 soccer players show lower levels of motivation at moments prior to the sports competition, and these dimensions of motivation are explained by the category, academic performance, and fat mass.
