This paper deals with psychological aspects involving bodybuilders nowadays, through their interests, motivations, factors that favor them to practice physical activity, frequent body image disorders, and major benefits that can be acquired when weight training the right way, whether physical or psychological. During the work is addressed to the Theory of Self-Determination and its characteristics, and behavioral aspects of the individual. We explore the types of motivation, intrinsic and extrinsic motivation, and their regulatory mechanisms. Did the relationship with weight training and the environment that surrounds it as the interaction between those involved in practice between the student and teacher performance and results and the effects that this interference can have on motivation and individual behavior. Also we relate body image factors, the perception of bodybuilders in relation to his own body, and the possible disorders that can promote. Describe the Vigorexia and their characteristics, we made a list of body image and self-esteem, approach standards set by society, the aesthetic influence and media disclosure. Finally, we explore the key benefits that well-directed physical activity can provide its practitioners. Physical, mental and social beneficial, improved self-esteem and in one's relationship skills. We address the growing strength in recent years, and their improvements in the various age groups and the population's quality of life

The sports activities occupy a growing space in people's lives, especially children and youth. Taking into consideration that this practice is of paramount importance, especially in childhood, where the acquired habits influence in adulthood, this work aims to investigate the role of physical education classes in adherence of children to the practice of some activity sports. These are a dynamic process, and to realize it is necessary planning, making the practice is a pleasurable activity. Thus, an important point to note is the motivation, which depends on extrinsic and intrinsic factors. Another factor that may interfere in the sporting practices is the influence of parents on children. In this context, the contact sports can be used to gain the approval of parents and not for self-gratification, this being a way to get closer to distant parents. A point worth mentioning is the physical education, as this introduces and integrates the child's body / movement culture. Often child's first contact with the sport happens at school, leading us to the assumption that the physical education teachers at the school are responsible for the athletic student motivation, and we emphasize that the school motivational factors are very dependent on students' aspirations for that a particular motivational element can take effect. The technical and / or professional outside of school physical education also influence the child, as these can provide pleasure for the sport, being a connoisseur of motivational strategies. An important motivational aspect is friendship, as children use sports activities to make new friends and find your friends. In addition, some extrinsic factors can influence the practice, such as: win, work out, play, socializing, competition, fun, etc. The drop can be caused by various reasons, such as early specialization, participation in very specific competitions for which the child is not yet ready. In addition, other factors can be...

Currently, health is one of the issues of concern of society. Health can be understood as a direct link between the practice of regular exercise and quality of life. Within this course of reasoning, comes the role of physical education professional. In this perspective, we have the Personal Trainer. Personal Trainer is the professional who makes exercise prescription, individually, with improvement goals fitness and others. This professional is someone trained in Physical Education and has qualification and training for that function. Thus, the aim of this study is to identify the reasons why the practitioners of physical exercise to train under the supervision of a Personal Trainer. To achieve the above goal was accomplished, a review of major studies on the subject. Thus, this work it is a research bibliography. On the literature review it is evident the professional demand due to a cultural change and, moreover, the need for and accessibility of this professional, the Personal Trainer. In addition, the adhesion of reasons in class Personal Trainer to give the competence of the professional in achieving goals and objectives of the student, respecting the individuality and motivation of each student, reasons that may be intrinsic or extrinsic. In Motivation respect, it is clear the need for deepening of the term, to be able to adequately meet the student

The conditioned rewarding effects of novelty compete with those of cocaine for control over choice behavior using a place conditioning task. The purpose of the present study was to use multiple doses of cocaine to determine the extent of this competition and to determine whether novelty’s impact on cocaine reward was maintained over an abstinence period. In Experiment 1, rats were conditioned with cocaine (7.5, 20, or 30 mg/kg ip) to prefer one side of an unbiased place conditioning apparatus relative to the other. In a subsequent phase, all rats received alternating daily confinements to the previously cocaine paired and unpaired sides of the apparatus. During this phase, half the rats had access to a novel object on their initially unpaired side; the remaining rats did not receive objects. The ability of novelty to compete with cocaine in a drug free and cocaine challenge test was sensitive to cocaine dose. In Experiment 2, a place preference was established with 10 mg/kg cocaine and testing occurred after 1, 14, or 28 day retention intervals. Findings indicate that choice behaviors mediated by cocaine conditioning are reduced with the passing of time. Taken together, competition between cocaine and novelty conditioned rewards are sensitive to drug dose and retention interval.

Grassland ecosystems have been severely reduced and grassland bird populations have experienced consistent declines. National Park Service (NPS) properties on the Great Plains provide breeding habitat for grassland songbirds, though little is known about the quality of this habitat. A short-term study on songbirds at three NPS properties complemented current monitoring, providing an among park comparison addressing grassland bird productivity and fidelity relative to NPS property size. During 2008-2009, I assessed avian species richness, and estimated bird density and grassland songbird nest success. Bird species richness was greatest at small and medium sites, while number of nesting obligate species was greatest at the large site. Species-specific densities varied among sites, with few grassland obligates occurring at all three sites. Nest success estimates for grassland obligates were highest at the small site and lower at the large site. Another method to quantify habitat quality is assessment of breeding site fidelity. Current extrinsic markers used in monitoring site fidelity are inadequate for small birds; stable isotope analyses provide an alternative. I compared two techniques for assigning stable isotope tissue origin and measured grassland songbird site fidelity. My method of assigning origin provided site-specific variances of expected stable isotope values, an improvement over the most commonly used method. Fidelity tended to be higher at the large site, which may indicate a more robust breeding community of grassland birds. The small size of two of my sites precluded large sample sizes and made strong inferences difficult. To quantify how scientists cope with weak inference, I conducted a literature review. Strong inference was rarely observed, and most authors of weak-inference papers provided specific management recommendations. I suggest that adaptive management is an ideal method to resolve uncertainty from weak inference. Managers should consider my results within the context of regional and global management and the extent to which their unit might aide songbird conservation.

Because GABA(A) receptors containing alpha 2 subunits are highly represented in areas of the brain, such as nucleus accumbens (NAcc), frontal cortex, and amygdala, regions intimately involved in signaling motivation and reward, we hypothesized that manipulations of this receptor subtype would influence processing of rewards. Voltage-clamp recordings from NAcc medium spiny neurons of mice with alpha 2 gene deletion showed reduced synaptic GABA(A) receptor-mediated responses. Behaviorally, the deletion abolished cocaine`s ability to potentiate behaviors conditioned to rewards (conditioned reinforcement), and to support behavioral sensitization. In mice with a point mutation in the benzodiazepine binding pocket of alpha 2-GABA(A) receptors (alpha 2H101R), GABAergic neurotransmission in medium spiny neurons was identical to that of WT (i.e., the mutation was silent), but importantly, receptor function was now facilitated by the atypical benzodiazepine Ro 15-4513 (ethyl 8-amido-5,6-dihydro-5-methyl-6-oxo-4H-imidazo [1,5-a] [1,4] benzodiazepine-3-carboxylate). In alpha 2H101R, but not WT mice, Ro 15-4513 administered directly into the NAcc-stimulated locomotor activity, and when given systemically and repeatedly, induced behavioral sensitization. These data indicate that activation of alpha 2-GABA(A) receptors (most likely in NAcc) is both necessary and sufficient for behavioral sensitization. Consistent with a role of these receptors in addiction, we found specific markers and haplotypes of the GABRA2 gene to be associated with human cocaine addiction.
