Introdução: A identificação de jovens atletas talentosos no desporto de alto rendimento requer uma abordagem multidisciplinar que considere a complexa cominação de características genéticas, psicológicas, físicas, técnicas e táticas, sendo o rácio 2D:4D uma possível ferramenta adicional.
Objetivo: Este estudo visa analisar, através de uma revisão sistemática e meta-análise, as relações entre o rácio 2D:4D e várias capacidades físicas em atletas de diferentes idades e níveis competitivos.
Metodologia: A pesquisa bibliográfica foi realizada nas bases de dados PubMed, Scopus, Web of Science e SPORTDiscus, com os artigos recuperados sendo importados para o software Cadima para otimizar a síntese de evidências e garantir rigor metodológico. A qualidade dos estudos foi avaliada utilizando a lista de “Downs e Black”, e a análise estatística da meta-análise foi efetuada com o modelo de Efeitos Aleatórios para considerar a variabilidade entre os estudos.
Resultados: Foram selecionados 67 estudos para a revisão da literatura, e 19 estudos, que avaliaram 3581 rácios 2D:4D, foram incluídos na meta-análise. Os principais resultados revelaram diferenças significativas entre homens e mulheres, com os homens apresentando valores de 2D:4D tipicamente mais baixos. Além disso, os atletas tendem a ter rácios 2D:4D inferiores em comparação com os não-atletas.
Conclusões: Foram identificadas associações negativas entre o rácio 2D:4D e a capacidade aeróbia, VO2máx, potência anaeróbia e força muscular, enquanto que as relações com velocidade, capacidade anaeróbia e flexibilidade mostraram-se menos consistentes.
Introduction: The identification of young talented athletes in high-performance sports requires a multidisciplinary approach that considers the complex interplay of genetic, psychological, physical, technical, and tactical characteristics, with the 2D:4D ratio potentially serving as an additional tool. Objective: This study aims to analyze, through a systematic review and meta-analysis, the relationships between the 2D:4D ratio and various physical capacities in athletes of different ages and competitive levels. Methodology: The literature search was conducted in the databases PubMed, Scopus, Web of Science, and SPORTDiscus, with the retrieved articles being imported into Cadima software to optimize evidence synthesis and ensure methodological rigor. The quality of the studies was assessed using the “Downs and Black” checklist, and the statistical analysis of the meta-analysis was performed using a Random Effects model to account for variability among the studies. Results: A total of 67 studies were selected for the literature review, and 19 studies, which evaluated 3581 2D:4D ratios, were included in the meta-analysis. The main findings revealed significant differences between men and women, with men typically exhibiting lower 2D:4D values. Additionally, athletes tend to have lower 2D:4D ratios compared to non-athletes. Conclusions: Negative associations were identified between the 2D:4D ratio and aerobic capacity, VO2max, anaerobic power, and muscular strength, while relationships with speed, anaerobic capacity, and flexibility was less consistent.
