Internal rotation of the hip when the knee is flexed. For its largest part, the biceps femoris runs superficially in the posterolateral thigh, sitting deep only to skin, fat and fascial layers. Therefore it has a major role in the gait cycle. Origin: Ischial tuberosity. You can expand your knowledge with the video tutorials and actively test yourself with our integrated quizzes. The muscles contain a higher proportion of type 2 muscle fibres than the other muscles of the lower extremity; suggesting high intrinsic force generation. The long head of the biceps femoris extends the hip, as when beginning to walk; both short and long heads flex the knee and laterally (outwardly) rotate the lower leg when the knee is bent.
