Forty\u2010six male soccer players completed different maximal isokinetic and isometric contractions of the knee extensors for the assessment of maximal strength (peak torque and maximal voluntary contraction (MVC) torque) and explosive strength (early, intermediate, late, and peak rate of torque development (RTD)). Self\u2010reported knee function was assessed with the International Knee Documentation Committee (IKDC) and Lysholm knee scoring scales. Peak torque and MVC torque showed comparable ILAs (8\u20109%), both being significantly lower than all RTD ILAs (16% on average; <jats:italic>p<\/jats:italic> &lt; 0.001). ILAs for early RTD (21%) and peak RTD (19%) were significantly higher than all the other variables (<jats:italic>p<\/jats:italic> &lt; 0.05). Only early and intermediate RTD were significantly correlated \u2013 though weakly \u2013 with both IKDC (rho = 0.32 for both) and Lysholm (rho = 0.36 and 0.30, respectively) scores. We conclude that explosive knee extensor strength \u2013 early RTD in particular \u2013 exhibited larger ILAs and better relations with self\u2010reported knee function than peak torque and MVC torque in professional soccer players. These results confirm the validity and functional relevance of early RTD and the need for its inclusion in routine performance testing for soccer players.<\/jats:p><jats:p><jats:bold>Highlights<\/jats:bold><\/jats:p><jats:p><jats:list list-type=\"bullet\">\n<jats:list-item><jats:p>Professional soccer players exhibited larger inter\u2010limb
