[EN] Some authors have suggested that body weight dissatisfaction may be high in students majoring in dietetics. Therefore, this study was conducted to examine the extent of body weight and image dissatisfaction in a sample of women in dietetics major. Additionally, predictors of magnitude of body weight dissatisfaction were analyzed. Participants were 62 volunteers with normalweight whose mean age was 21.87±1.89 years old (nonrandom sample). The assessment instruments included anthropometric measurements, a somatomorphic matrix test and an eating disorders inventory (EDI-2). Data were analyzed using SPSS vs. 15.0. A larger proportion of students chose an ideal body weight lower than actual weight (67.7%) and body image with less body fat and more muscle mass than actual values (56.4%). The magnitude of body weight dissatisfaction was associated with muscle mass and body fat dissatisfaction, and with the subscale of EDI-2 “body dissatisfaction”. So, from a public health standpoint, we consider important to continue working in this line of research with the aim of better understanding the extent of body weight dissatisfaction in women dietitians, and how this dissatisfaction could interfere with their professional practice.

A diario, mucha gente se ve obligada a comer lejos de su casa ya que, los apretados horarios, el trabajo, los estudios, la distancia u otros motivos no le permiten acudir a su hogar a almorzar tranquilamente. Además, los recortes sufridos por la crisis en los presupuestos de la mayoría de los hogares y empresas, han llevado a que muchas de esas personas no puedan acudir a comer a restaurantes y tengan que llevarse la comida preparada de su casa para comerla en la calle. Para dar solución a este problema, cada vez más presente en nuestra sociedad, en este Trabajo de Fin de Grado se ha ideado el recinto EATING POINT. Enmarcado dentro del servicio de deportes de los ayuntamientos, permite a sus usuarios comer su propia comida en un lugar agradable y en el centro de su ciudad. A lo largo del trabajo, se expone un plan de negocio para esta entidad deportiva, haciendo hincapié sobretodo, en lo referente a su plan de marketing, el cual se ha desarrollado siguiendo los criterios del marketing para el ámbito de los deportes. Además, se analiza la evolución del marketing deportivo, la política estratégica deportiva, el análisis de gestión y el marketing mix en los servicios deportivos.

The dynamic interaction of limb segments during movements that involve multiple joints creates torques in one joint due to motion about another. Evidence shows that such interaction torques are taken into account during the planning or control of movement in humans. Two alternative hypotheses could explain the compensation of these dynamic torques. One involves the use of internal models to centrally compute predicted interaction torques and their explicit compensation through anticipatory adjustment of descending motor commands. The alternative, based on the equilibrium-point hypothesis, claims that descending signals can be simple and related to the desired movement kinematics only, while spinal feedback mechanisms are responsible for the appropriate creation and coordination of dynamic muscle forces. Partial supporting evidence exists in each case. However, until now no model has explicitly shown, in the case of the second hypothesis, whether peripheral feedback is really sufficient on its own for coordinating the motion of several joints while at the same time accommodating intersegmental interaction torques. Here we propose a minimal computational model to examine this question. Using a biomechanics simulation of a two-joint arm controlled by spinal neural circuitry, we show for the first time that it is indeed possible for the neuromusculoskeletal system to transform simple descending control signals into muscle activation patterns that accommodate interaction forces depending on their direction and magnitude. This is achieved without the aid of any central predictive signal. Even though the model makes various simplifications and abstractions compared to the complexities involved in the control of human arm movements, the finding lends plausibility to the hypothesis that some multijoint movements can in principle be controlled even in the absence of internal models of intersegmental dynamics or learned compensatory motor signals.

[EUS] Elikadura oso garrantzitsua da errendimendurako txapelketa batean. Horrez gain, lehiaketa batzuetan, kirolariak kategoria ezberdinetan sailkatzen dira beren pisuaren arabera, kyokushin karatean bezala. Arte martzial honetako lehiakide askok txapelketaren aurreko egunetan dieta gogorra egin behar dute, ahalik eta kategoria baxuen egoteko asmoz. Batzuetan, barauan edo afaldu gabe joaten dira hori lortzeko. Horregatik, ikerketa honetan pisua hartu eta gero eta lehiatu aurretik elikadurazko estrategia ezberdinak aztertu ziren. Kontrola egin baino lehen, karbohidratoak eta proteinak hartu behar izan zituzten partaideek, eta indarra, erresistentzia, bizkortasuna eta potentzia baloratu egin zen. Kancho Oyama gimnasioan egin ziren frogak. Horietan 12 karatekak hartu zuten parte, batzuk emakumezkoak (4) eta beste batzuk gizonezkoak (8), 18 urte baino gehiagokoak izanda. Ikerketaren emaitzak, partaide gehienak indarrean, erresistentzia eta bizkortasunean karbohidratoekin eta potentzian proteinekin hobetu egin zutela markatu zuten. Ere esan dezakegu, errendimenduan mutilek neskek baino gehiago hobetzen dutela. Goizean arratsaldean baino errendimendu hobea nabarmentzen da, kontuan izanda, pisua hartu baino ordu batzuk lehenago jan barik daudela. Iraupen gutxiko eta intentsitate altuko kontaktuko kiroletan, txapelketa baino lehen ohiturak funtsezkoak dira, hala nola, ondo deskantsatzea, aurre entrenamenduak eta elikadura adibidez, horretaz gain, karbohidratoak hartzen baditugu pisua hartu eta gero normalean errendimendu gehiago lortzen da proteinekin baino, ondorio aipagarriena izanik.
