>>12137733The odd posture you see in those photos are most likely caused by quadricep tears as the result of a combination of anabolic steroid abuse and rectal injuries.
Anabolic steroids interfere with the normal process of collagen synthesis, which is essential for maintaining the strength and integrity of tendons and muscles. Long-term use of steroids can make the quadriceps tendon more prone to tearing when subjected to heavy loads or sudden movements.
Furthermore, rectal injuries can cause quadriceps tears in a few ways. One possible mechanism is through the transmission of force from the rectum to the quadriceps muscle. The rectum is located in close proximity to the pelvic floor muscles, which include the quadriceps muscle group. When a person experiences trauma to the rectum, the force of the impacts can be transmitted to the quadriceps muscle, leading to a tear. The rectum is furthermore supplied by several arteries that also supply blood to the quadriceps muscle. If one of these arteries is damaged during a rectal injury, it can lead to a decrease in blood flow to the quadriceps muscle, which can cause it to weaken and tear.
