NRL players are required to wear extensive protective equipment to prevent injury during competition. What is the most accurate description of how shoulder pads can physiologically support the musculoskeletal system to reduce the risk of injury?
Absorb the shock of impact collisions when being tackled by opposition players, reducing the risk of injury to the shoulder joint.
Absorb and distribute the shock of impact collisions when being tackled by opposition players, reducing the risk of injury to the shoulder joint.
Players can block the opposition from the play more effectively.
There is no physiological benefit to wearing shoulder pads.
