Resumo
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.
