Abstract (EN): Introduction: Muscle fatigue could have a greater impact on position sense when antagonists of the movement are fatigued. Hence, this study aimed to compare the effects of antagonist and agonist exercise-induced muscle fatigue on knee joint position sense. Methods: This within-subjects repeated-measures study included 40 subjects. Knee position sense and muscle strength were measured before and after two exercise protocols consisting of 30 consecutive maximal concentric/eccentric contractions of the knee extensors or flexors on the isokinetic dynamometer at an angular velocity of 180 degrees/s (3.14 rad/s). Results: Both exercise protocols increased the absolute angular error (F-1.78 = 39.89, P < 0.001; knee extensors protocol from 2.0 +/- 1.3 degrees to 3.5 +/- 2.0 degrees, knee flexors protocol from 2.1 +/- 1.2 degrees to 3.7 +/- 2.2 degrees), and no differences were detected between protocols (F-1.78 = 0.034, P = 0.855). No changes were observed in the relative angular error. Conclusions: Muscle fatigue affects knee position sense, and the deleterious effect is not different depending upon the muscle group fatigued.
