https://doi.org/10.47197/retos.v68.115407Palavras-chave:
Desporto, jogadores de padel, saúde mental, ansiedade, frustração, stressResumo
Introdução: Os fatores psicológicos são essenciais para compreender e melhorar o desempenho no padel, pois influenciam a forma como os jogadores lidam com as exigências físicas e emocionais deste desporto.
Objectivo: Esta revisão sistemática tem como objectivo identificar e analisar as principais variáveis psicológicas estudadas em relação ao padel, incluindo a frustração, ansiedade, stress, auto-confiança e fadiga mental.
Metodologia: A revisão seguiu as diretrizes PRIS-MA e envolveu uma pesquisa abrangente em quatro bases de dados principais: PubMed, Web of Science, Scopus e SPORTDiscus, até agosto de 2024. Após a aplicação dos critérios de inclusão e exclusão, foram selecionados 12 estudos de um total de 1.384, com 1.021 participantes. A maioria dos estudos foi descritiva, transversal e comparativa, sendo que apenas um adotou um desenho experimental.
Resultados: A revisão revelou que as variáveis psicológicas mais investigadas no padel são a ansiedade, a autoconfiança e a fadiga mental induzida pelo stress. Uma descoberta consistente em todos os estudos foi que os jogadores experimentam frequentemente níveis elevados de ansiedade e stress antes das competições, ao mesmo tempo que mantêm níveis elevados de autoconfiança. Além disso, os jogadores com maior experiência e níveis competitivos mais elevados tendem a gerir as exigências psicológicas de forma mais eficaz do que os seus colegas menos experientes.
Discussão: Estes resultados sugerem que a preparação psicológica e o treino mental podem ser cruciais para melhorar o desempenho no padel.
Conclusão: Esta revisão destaca a importância da preparação psicológica e do treino mental para melhorar o desempenho no padel.
