What Do Children Think of Their Perceived and Ideal Bodies? Understandings of Body Image at Early Ages: A Mixed Study.

Research into children's body perceptions and ideals is scarce despite evidence of body dissatisfaction in childhood. This study aimed to understand preschoolers' body image by employing a mixed design. Using a novel figural scale (Preschoolers' Body Scale) that comprises four child figures ranging in BMI, 395 children ages 4-6 (54% boys) selected their perceived and ideal body and explained why they picked these bodies.

Teaching and Learning Process of Decision-Making Units in Talented Young Players From U-10 to U-14.

There are multiple factors that have been studied for talent identification (TI) with regard to sport performance, such as physical and physiological parameters; psychological, social, and contextual parameters; and technical-tactical parameters. However, despite the importance of these indicators for reaching the elite, new trends seem to assure that one of the key elements in a young player is decision making (DM). Thus, in the last decades, research DM in young players has increased.

Body Dissatisfaction in Adolescents: Differences by Sex, BMI and Type and Organisation of Physical Activity.

The aim of this study was to assess the differences in body dissatisfaction (BD) of male and female adolescents by body max index (BMI) and the quantity, type and organisation of physical activity (PA). To do so, 652 adolescents aged 12-17 years participated in a cross-sectional study. The cognitive-affective component of BD was assessed with the Body Shape Questionnaire (BSQ) and the perceptual component with Gardner's scale for the assessment of, body image (BI).

The Way to Increase the Motor and Sport Competence Among Children: The Contextualized Sport Alphabetization Model.

There is a concern to implement games that will be able to increase the students' during the sport contents in Physical Education. Some games encompassed in Models-Based Practice (MsBP) are more beneficial for physical and physiological development than others. The main purpose of this study is to compare the degree of physical and physiological performance in several futsal games that have been implemented through two MsBP: the (TGfU) and the (CSAM).

Analysis of Tactical, Decisional and Executional Behaviour according to the Level of Expertise in Squash.

The objective of this study was to analyse the differences in tactical principles, decision-making and execution of the return shot and drop shot of squash players at different levels of proficiency. The sample was composed of 80 players, divided into four levels of expertise (first national category, second national category, autonomous regional level and provincial level). The Squash Performance Evaluation Tool was used for recording the level of decision-making and execution.

Muscle dysmorphia: detection of the use-abuse of anabolic adrogenic steroids in a Spanish sample.

Due to a distortion in the body image, the people who suffer from muscle dysmorphia have the self-perception of being less muscular than they currently are. With the aim of increasing their muscular development, they resort to the use of AAS. The purpose of the present study is to know the prevalence of the use of AAS in a Spanish sample affected by muscle dysmorphia.

Functional Assessment and Injury Risk in a Professional Soccer Team.

At the last World Conference on Sport and Physical Therapy celebrated in Bern (Switzerland, 2015), it was confirmed that the functional skills of an athlete are a very important variable to be considered in the recovery of an injury. On the other hand, its use as a predictive risk tool still lacks solid evidence. The purpose of this study was to determine whether a battery of functional tests (FPT) could be used as a preliminary measure for the season in order to identify the injury risk in a professional soccer team in the Spanish Second Division B League.

Physical perceptions and self-concept in athletes with muscle dysmorphia symptoms.

Individuals affected by Muscle Dysmorphia (MD; body image disorder based on the sub estimation of muscle size), practice weightlifting in order to alleviate their muscular dissatisfaction. Although physical activity is associated with increased physical self-perception, we assume that this was not reproduced in full in people with MD. The study sample consisted of 734 weightlifters and bodybuilders, 562 men and 172 women, who completed the Escala de Satisfacción Muscular, the Physical Self-Concept Questionnaire, and from whom measures of body fat and Fat -Free Mass Index (FFMI) were obtained.

The relative age effect in youth soccer players from Spain.

The purpose of this study was to identify the existence of Relative Age Effect (RAE) at youth level in both elite and amateur Spanish soccer clubs, and also to carry out an analysis providing with information on how this effect has evolved in recent years. We have obtained information on the youth teams of the 20 clubs belonging to the Spanish Professional Football League (LFP) in two separate seasons (2005-2006 and 2008-2009) as well as data on five youth academies belonging to amateur clubs. The collected data revealed an over- representation of players born in the first months of the selection year in all groups of analysis (Elite 2005-2006, Elite 2008-2009 and Amateurs), although only the Elite groups showed significant variations in birth-date distribution in relation to the Spanish population.
