Abstract
Isokinetic strength evaluation of the quadriceps (Q) and hamstrings(H), in both concentric (con) and eccentric (ecc) mode of contraction, is an important part of the comprehensive evaluation and rehabilitation of athletes. Systematic preseason isokinetic evaluation of the knee is very useful in highlighting the athletes at risk for those injuries as well as for the optimization of the training process. The main purpose of this short review was to present the major findings of studies relating to this issue.
