Antecedentes: el levantamiento de pesas paralímpico es un deporte de fuerza. Por otro lado, se ha investigado la relación entre los indicadores de fuerza y la relación entre las longitudes del segundo y cuarto dedo de la mano (D2:D4).
Objetivos: Evaluar la relación de la relación de longitud de los dedos D2:D4 con el rendimiento en levantamiento de pesas paralímpico. Metodología: Trece atletas de levantamiento de pesas paralímpico de élite fueron evaluados en cuanto a indicadores de fuerza estática, tasa de desarrollo de fuerza (RFD), fuerza isométrica máxima (MIF), impulso, variabilidad y tiempo hasta MIF. Se midieron las relaciones D2:D4 y se hicieron correlaciones entre las diversas posibilidades de relaciones D2:D4 y los indicadores de fuerza estática. Resultados: Se encontraron correlaciones moderadas entre RFD y Left D4 ("r" = 0,569) y entre Variabilidad y R-L D2:D4 Diferencia. ("r" = 0,570). Sin embargo, no se encontró correlación entre las proporciones D2:D4 y los indicadores de fuerza estática en atletas de levantamiento de pesas paralímpicos para las otras variables. Conclusión: La relación D2:D4 no parece ser un predictor confiable de los indicadores de fuerza estática en atletas de Powerlifting Paralímpico.

Abstract. Background: Paralympic Powerlifting is a strength sport. On the other hand, the relationship between force indicators and the ratio of the lengths of the second and fourth fingers of the hand (D2:D4) has been investigated. Objectives: To evaluate the relationship of the D2:D4 finger length ratio with performance in Paralympic Powerlifting. Methodology: Thirteen elite Paralympic Powerlifting athletes were evaluated for static force indicators, Rate of Force Development (RFD), Maximum Isometric Force (MIF), Impulse, Variability, and Time to MIF. The D2:D4 ratios were measured, and correlations were made between the various possibilities of D2:D4 ratios and static force indicators. Results: Moderate correlations were found between RFD and Left D4 ("r" = 0.569) and between Variability and R-L D2:D4 Difference. ("r" = 0.570). However, no correlation was found between D2:D4 ratios and static force indicators in Paralympic Powerlifting athletes for the other variables. Conclusion: The D2:D4 ratio does not seem to be a reliable predictor of static force indicators in Paralympic Powerlifting athletes.
