These results are in conflict with the alterations of biceps femoris muscle during jump in another study.
This theory is based on an observed partial attachment of the long head of the biceps femoris muscle to the sacrotuberous ligament, which bridges the sacroiliac joint.

The long head of the biceps femoris muscle is considered to be the prime mover of hip extension and external rotation knee accessory.
The common peroneal nerve is also at risk during this approach as it branches off the tibial nerve and descends along the medial margin of the biceps femoris muscle. A lesion to this nerve will result in "foot drop" due to paralysis of the muscles responsible for foot dorsiflexion.
The common peroneal nerve originates from the sciatic nerve, passes posteriorly and laterally to the biceps femoris muscle in the popliteal fossa, crosses the head of the fibula, and descends the lower leg.
The pH of biceps femoris muscle was measured in triplicates following the procedure of Bendall (1973) using a portable pH meter (Sentron Argus-X, Roden, Netherland).
Three investigations did precisely identify the long head as the specific component of the biceps femoris muscle that was most frequently injured (De Smet and Best, 2000; Garrett et al., 1989; Slavotinek et al., 2002), while one also described five minor injuries involving the short head (Slavotinek et al., 2002).
