Abstract(s)
A atividade física (AF) contribui de forma positiva para saúde dos adolescentes. Assim, o papel de mediação do suporte social entre a perceção de barreiras e benefícios (BB) na AF e os níveis de AF necessitam e devem ser explorados. O objetivo deste estudo foi analisar a associação entre BB na AF, suporte social e níveis de AF em adolescentes, e o papel de mediação das BB.
Métodos: Os participantes foram adolescentes (n=497) de ambos os sexos (M= 16,15; SD= 1,59). As variáveis psicossociais e os níveis de AF foram recolhidas através de questionários. Foram realizados procedimentos para análise das relações estruturais e análise da mediação.
Resultados: O modelo proposto ajustou-se aos dados e mostrou um critério de invariância entre sexos. A mediação completa foi observada, nomeadamente o caminho entre o suporte social dos pais, amigos e melhores amigos e os benefícios percebidos na AF e níveis de AF.
Conclusões: Em conclusão, o suporte social, sobretudo do melhor amigo e os benefícios percebidos na AF, parecem ter interferência nos níveis de AF, independentemente do sexo do adolescente.
Physical activity (PA) represents a healthy way in adolescents. However, the mediation role of social support between perceived benefits and barriers (BB) to PA and PA needs to be explored. The aim ostudy was to analyze the association between BB to PA, social support and PA levels in adolescents, and the mediation role of BB. Methods: Participants were adolescents (n=497) of both sexes (M= 16.15; SD= 1.59). Psychosocial variables and PA were collected by self-reported measures. Structural equation modeling and mediation analysis were performed. Hypothesized model fit the data and showed an invariance criterion between sexes. Results: Full mediation was observed, namely the path between social support from parents, friends and best friend’s and perceived benefits to PA and levels of PA. Conclusions: In conclusion, social support, especially from best friend and perceived benefits to PA, seems to be implications for levels of PA, independently of the adolescent sex.
