Injuries to the knee are the most common, but injuries to the shoulder and back are also common. (See the injury section of this article for more information.) Certain sports require different techniques for injury prevention.
In soccer, players can play for hours without any injury. In hockey, players can play for hours without any injury. In football, players are often injured on the field, not off it. In rugby, players often suffer lower-leg injuries when tackling each other. Injuries to the body tend to be less severe than serious injuries sustained in sports. Usually, injuries to the body are minor but tend to occur in the same areas as serious injuries to the body.
Injuries are different for each sport, and are usually treated differently for each sport. Most athletes make a return to play in less than six months. Some athletes do not return to play until a year or more after injury. The most common injury is a muscle strain.
Other common injuries include a broken bone, a concussion, or a dislocated shoulder. The most common injury occurs during a tackle. A tackle can occur during a play, when a player is applying force to an opposing player or when a player is trying to separate an opposing player from an offensive player. Tackles can be performed in either the offensive or defensive positions, but they are most commonly performed in the defensive position. Most tackles take place on the ground.
Players are expected to make contact with their opponent as they try to separate the opposing player from the ball. Injuries can occur in the tackle as well as during a play. If a player is injured while trying to separate an opposing player from the ball, the other team will likely attempt to recover the injured player. A player may be carried to the sideline by the opposition team and eventually return to the field. The most common injury is medial collateral ligament (MCL) tears. Take the case of New York Giants defensive end Jason Pierre-Paul, who tore his ACL in his right knee during training camp in 2012, when he was playing for the Tampa Bay Buccaneers.
A few weeks later, he ruptured his medial collateral ligament (MCL) in his left knee during a game against the Washington Redskins. Different teams have different injury-prevention protocols. The Seattle Seahawks, for example, require all players to wear a protective boot when they are on the field. The Minnesota Vikings require all players to wear a knee brace while on the field. Another injury that is often sustained during the offseason is a bulging disk. A bulging disk is a large, soft, soft mass of tissue that forms around the back of the knee, and is the most common injury on the knee.
Although the overall incidence of injuries is low (7.6 injuries per 1,000 players per year), it is notable that this number is higher among players that run at speeds of 65 km/h (40 mph) or more. The impact of running is most clearly seen in collisions with the net as opposed to in collisions with the ball. If there is a collision with the net, this creates a high degree of stress on the body. Injuries that occur during contact with the net (for example, the ball) are uncommon. Box 1.
