Muscular strength is one of the important physical fitness components. Higher strength levels might contribute avoiding injury risks and facilitate technical movements’ accomplishment. The purpose of the current study was to examine the strength and functional flexors-to-extensors ratio difference in the knee and elbow joints between athletes practicing dissimilar combat-sports (i.e., amateur boxing, taekwondo, karate, and judo). Forty-four male athletes (11 in each sport) aged 24.3 ± 2.4 years voluntarily participated in the study. Peak torques of flexors and extensors of elbows and knees were measured using an isokinetic device at three different angular velocities (i.e., 60, 120, and 180°/s). To compare between groups differences, one-way ANOVA with Bonferroni post-hoc test were been utilized. The results showed significant peak torque differences of both (knee-and-elbow) muscles among dominant and non-dominant limp (p < 0.01). Also, our findings demonstrated that irrespective of the angular velocity, significant functional flexors-to-extensors strength ratio (F/EFUNC ratio) variances among the dominant and non-dominant limbs have been reported (p<0.001). Identifying dissimilarities between muscle extensors and flexors, plus dissimilarities in F/EFUNC ratio at different angular velocities could help in reducing risk of injury, and enhancing physical fitness performance, and then technical and tactical ones.
