L'analyse statistique des resultats amenent l'auteur aux conclusions suivantes : - L'entraineur est en general percu comme etant peu anxiogene. Toutefois les comportements de communication et dans une moindre mesure les comportements revelant une tension emotionnelle perturbent le plus les athletes. - Les entraineurs les plus anxiogenes sont moins bien percus par les athletes et ont des comportements d'entrainement de support social et de renforcement peu eleves avec un style de decision plus autocratique. - Les athletes percevant leurs entraineurs comme plus anxiogenes sont eux-memes plus anxieux et moins confiants en eux ; prennent moins de risque et sont moins combatifs dans la defense de positions personnelles. - Les groupes dont les entraineurs sont percus comme plus emotionnellement perturbateurs semblent susciter chez les sportifs une attraction plus reduite pour les activites sociales.

This situation implies a public health problem since it has been shown that drugs such as Steroids, Stimulants, Erythropoietin, and Human Growth Hormone has significant performance-enhancing effects, which can lead to dangerous side effects or even fatal with long-term use. This systematic review aimed to analyze studies that describe attitudes, beliefs and knowledge, as conceptualized in Theory of Planned Behavior (TPB) influenced by the use of PES by gym/fitness center users and provide a framework on the state of the art in this theme, and thus allow the design and foundation of future research lines. Twenty-six articles were identified from a systematic approach following the PRISMA Statement via electronic databases and hand-searching bibliographies of reference lists. Only peer-reviewed primary research published in English, Portuguese and Spanish (1997-2016), focusing on gym/fitness center users regardless of age and gender and provide some information on psychosocial factors towards using PES were included in this review. Emergent themes conceptualized with the TBP concluded that the main reasons pointed for young male bodybuilders using steroids as a prevalent drug, regards aesthetic issues, improve muscle size, strength and performance. Important influences come from groups and instructors. Drugs are obtained from a variety of sources. Predisposition related to steroid use increase with years of physical training. Although some steroid users indicated a general lack of knowledge of the potentially harmful effects of drugs, others had high knowledge about drug's side effects. The TPB illustrated a relationship between psychosocial factors influencing gym users to use PES. TPB could be used in future research to provide a template when developing prevention programs to reduce the use of PES and promote new lines of investigation on this study groups, as well as different PES than steroids.info:eu-repo/semantics/publishedVersio

Quatrocentos e quarenta e oito adolescentes preencheram o Emotional Quotient Inventory: Youth Version (EQ-i:YV) e a Satisfaction with life Scale (SWLS). A IE e a satisfação com a vida indicada por adolescentes envolvidos na prática desportiva federada foi significativamente superior comparando com os não praticantes. Os praticantes não federados indicaram, ainda, uma perceção de IE interpessoal significativamente maior do que os não praticantes. O género e a idade não demonstraram ter influência na IE e na satisfação com a vida dos adolescentes, com exceção de alguns fatores da IE, ao nível do género. Estes dados sugerem que a IE e satisfação com a vida estão intimamente correlacionadas com a prática desportiva.

De facto a psicologia do desporto é uma disciplina científica, mas também uma área profissional. Enquanto área profissional, a psicologia do desporto refere-se à prática da psicologia por profissionais que se especializaram no trabalho com atletas ou outros agentes que estejam relacionados com o desporto ou com o exercício. Enquanto disciplina científica, a psicologia do desporto surge do desenvolvimento académico oriundo das universidades relacionadas com as ciências do desporto, motricidade humana, ou educação física. Aqui, o estudo da psicologia do desporto relaciona-se tanto com os factores psicológicos que influenciam a participação no desporto e exercício, como com os efeitos psicológicos derivados dessa participação 2. A maior diferença entre as actividades profissionais e as actividades científicas é a de que o primeiro grupo trabalha numa área aplicada-a prática de psicologia nos contextos de actividade desportiva e de exercício-enquanto que o segundo grupo trabalha ao nível da investigação, do desenvolvimento de teorias e, mais recentemente, com a aplicação do conhecimento obtido no «terreno» desportivo. Os especialistas em psicologia do desporto, tanto investigadores como profissio-359

Participants were 47 football referees from the 1st Portuguese Professional Football League evaluated through an open question: "write down what refereeing means to you". The analysis was made according to Miles & Huberman (1994) procedures. The 5 categories are: relation with the football; costs of the practice; emotion for the arbitration; social interaction and way of life. The results show that be connected to the world of the football, passion and the relationship with other referees are important motivational factors, with that the referees have a high grade of excitement and pleasure in his labor activity. on the other hand the task of refereeing is generating of stress and burnout.

A convenience sample of Portuguese gym users (n = 453) completed an anonymous web-based survey. Structural equation modeling, multigroup analysis, and t-test with the Welch correction for heterokedastic variances were used. At the structural level, results support attitudes, beliefs, and subjective norms in predicting intentions to PES use in gym users, with subjective norms being its strongest predictor. Moreover, results showed a significant association between self-reported PES use and intentions to use. The predictive model was invariant across genders; however, compared to males, females believed less in the performance-enhancing effects of PES, were less prone to the influence of significant others, and had weaker intentions to use these substances. Psychological strategies should be based on subjective norms, alongside beliefs and attitudes, toward PES use as these variables influence the intention to use PES in this particular population.
