O que pensam os treinadores portugueses da 1ª liga sobre a importância da intervenção psicológica no futebol profissional? / What portuguese premier league coaches think about the importance of psychological intervention in professional soccer?

O rendimento desportivo resulta da interligação de aspectos físicos, técnicos, tácticos e psicológicos. Contudo, relativamente ao treino de Futebol constata-se que a componente psicológica é muito negligenciada. Neste estudo, procura-se conhecer as percepções de treinadores de alto rendimento acerca de diferentes aspectos relacionados com a dimensão psicológica, nomeadamente as concepções sobre o treino psicológico e a sua relação com o treino e o rendimento desportivo; o nível de preparação dos treinadores para treinar as competências psicológicas; e a relevância de colaborar com um especialista em psicologia do desporto. Com recurso a uma entrevista semi-estruturada, foram entrevistados quinze treinadores da Primeira Liga de Futebol Portuguesa. Uma análise indutiva das entrevistas revelou que os treinadores atribuem grande importância à componente psicológica e à colaboração com um especialista em psicologia do desporto, até porque não se sentem preparados para desenvolver um treino sistemático neste domínio.

Sport performance results from the interaction of physical, technical, tactical and psychological aspects. However, in Soccer training less attention is devoted to the psychological domain. The purpose of this study was to investigate elite Soccer coaches’ perceptions concerning different aspects of the psychological dimension, namely the conceptions about mental training and his relationship with training, in general, and performance; the coaches’ level of preparation to apply a specific psychological training; and the collaboration with a sport psychology expert. Using in-depth interviews, fifteen coaches of the Portuguese first league were interviewed. The interviews showed that the coaches attribute great significance to the psychological domain and to a possible collaboration with a sport psychology expert, as coaches seem to be unprepared to apply specific mental strategies or are unfamiliar with them.

A prática desportiva dos estudantes universitários e suas relações com as autopercepções físicas, bem-estar subjectivo e felicidade / University students' sport practice and its relations with physical self-perceptions, subjective well-being and happiness

A presente investigação analisou as relações entre a prática desportiva de estudantes universitários e o modo como estes se percepcionavam a si próprios e às suas vidas. Participaram nesta investigação 2284 estudantes de ambos os sexos, com idades entre os 18 e os 30 anos (M = 21,87 ±2,37), que preencheram um questionário sobre a sua prática desportiva, bem como versões portuguesas do Physical Self-Perception Profile (Fox & Corbin, 1989), da Subjective Happiness Scale (Lyubomirsky & Lepper, 1999), da Satisfaction With Life Scale (Diener, Emmons, Larsen, & Griffin, 1985) e da Positive and Negative Affect Schedule (Watson, Clark, & Tellegen, 1988). Em geral, a análise dos resultados revelou que os indivíduos que possuíam mais confiança física e que avaliavam a sua vida mais positivamente praticavam desporto mais regularmente; porém, verificou-se igualmente que quem se percebia menos forte fisicamente e tinha uma auto-estima mais baixa também praticava desporto mais regularmente do que os pares.
