Abstract

INTRODUCTION: The knee joint is one of the biggest and most complex joints of the body. Optimal function of the knee joint is closely related with the physical performance and the outcome of sporting activity. Consequently, there have been many studies related to the muscles of the knee joint. The majority of these have focused on 90┬░range of knee movement, and the same start-angle and end-angle. However, during normal exertion and in sports, different actions require a different range of movement of the knee joint. In addition, the muscular force and velocity are also different. Therefore, in this paper, the biomechanical characteristics of knee muscles in different ranges were studied.
