Leg Guard Function

The shin guard is to protect the calf (with the development of technology, some shin guards can also protect the ankle), so it is also called

For shin guards. Due to the highly confrontational nature of football games, it is very common for players to be kicked to the calf. In physics, the shin guard is to disperse and buffer the pressure and impulse exerted on the calf to protect the player. Leg guards are generally rigid boards that can disperse the force exerted by the opponent's legs and shoes. In addition, the gap between the leg guard and the leg can play a buffering role, and the skin between the leg bones and the leg guard can also buffer to prevent fractures.

So what are the hazards of not wearing leg guards? Tibia or fibula fractures can occur when players do not wear leg guards and violence is applied to the calves. In severe cases, it can cause thigh femoral fractures or knee cruciate ligament tears. Leg guards can reduce the incidence of calf fractures. When the tibia is fractured, the lower limbs cannot bear the weight of the body, so it is easy to break. The diagnosis of fibula fracture is relatively difficult, because the fibula is a non-weight-bearing bone, even if a fracture occurs, athletes can continue to compete. Since the fibula is a non-weight-bearing bone, the stress is less, so the fracture healing time is longer. FIFA mandates that athletes must wear leg guards when participating in the game (see Chapter 4 of the Football Rules: Football players must wear leg guards made of plastic, rubber and other similar materials, and the leg guards must be used by football The socks are completely wrapped) to avoid calf fractures. The treatment of fibula fractures of football players is not much different from other events, but because football players themselves have higher requirements for calf muscles, it takes a relatively long time to fully recover enough to play football again.
