摘要：Abstract The leg-extension exercise is a universally recognized exercise, proposed for the analytical strengthening of the quadriceps muscle (Fig.1). Its applicability especially in rehabilitation and in the fitness field, today, is being much questioned by literature, particularly by those concerning rehabilitation of knee pathologies. This current orientation finds ample evidence in relation to the important patello-femoral joint compressive forces that the knee extension can create9. Despite the leg extension machine being invented to solicit selectively the thigh musculature without placing excessive loads on the spine, and potentially, the risk of injury increases as the knee and lower leg do not work correctly. Furthermore, in soliciting the lower extremities by sitting at an angle of 90°-120° between the pelvis and the spine, the latter is maintained verticalized at the lumbar region and this inversion of curves is not free from risks in hypomobile subjects or suffering from spinal pathologies. The object of this study is to analyze the validity of the exercise in an open kinetic chain defined as “leg-extension”.
