MODEL OF THE KNEE FOR UNDERSTANDING THE SQUAT MOVEMENT BIOMECHANICS

By means of MSC Adams- BRG LifeMOD software, a three dimensional lower extremity model has been developed in this study. This model take into account 16 muscles, 4 ligaments, 2 tendons in order to quantify forces and contacts (patello-femoral and tibio-femoral) during muscular training movement (e.g. a squat) with various raised loads (0, 20 and 30 kg). The first results showed the importance of the relationships between muscle activations (e.g. Quadriceps, Hamstrings) and ligament forces (e.g. Anterior and Posterior Cruciate Ligaments).
