Knee injuries come in a variety of types. Very frequently, we see injuries to the ACL, or MCL, or both. In addition, meniscus tears are quite frequent with either of those types of injury (especially ACL tears). Some trainers have access to cryotherapy units, which are very useful on the field for inflammation and pain control. Ice bags are also commonly used. For an easier way to ice your knee. Shoulder injuries. There are two common types of shoulder injuries sustained in football: Shoulder dislocation Typically, this is reduced on the field by the trainer or doctor (or coach). If the shoulder is unable to be reduced, the player is usually sent emergently to the hospital for reduction in the emergency room. AC separation An AC separation is also known as a "separated shoulder". This is a tear of the ligaments between the clavicle and acromion bone, which causes the clavicle (collar bone) to stick up. Most of these are treated without surgery, although rehabilitation is often required before returning to play. To reduce swelling and discomfort in your shoulder, cryotherapy is a great option.
The objective of this game is to score more points than the other team during the allotted time. The team with the ball (the offense) has 4 plays (downs) to advance at least 10 yards, and can score points once they reach the opposite end of the field, which is home to a scoring zone called the end zone, as well as the goal posts. If the offense succeeds in advancing at least 10 yards, they earn a "first down" and the number of tries allotted is reset and they are again given 4 tries to advance an additional 10 yards, starting from the spot to which they last advanced. If the offense does not advance at least 10 yards during their 4 downs, the team without the ball (the defense) regains control of the ball (called turnover on downs). On offense, points are scored by advancing the ball into the opponent's end zone for a touchdown (worth six points), or by kicking the ball from the playing field through the raised vertical posts (the goal posts) which are most commonly situated on the end line of the end zone for a field goal (worth three points). After scoring a touchdown, the offense is given an additional opportunity from the 2-yard line (3-yard line in amateur football) to attempt to score (in the NFL, 15-yard line on 1-point conversions). Conversion attempts are used to score 1 or 2 points as follows: The offense may attempt a field goal kick which is worth 1 point. The offense may attempt to re-advance the ball into the opponent's end zone for a two-point conversion worth 2 points. While the opposing team has possession, the defense attempts to prevent the offense from advancing the ball and scoring. If an offensive player loses the ball during play (a fumble) or the ball is caught by a defensive player while still in the air (an interception), the defense may attempt to run into the offense's end zone for a touchdown. The defense may also score points by tackling the ball carrier in the offense's own end zone, called a safety (which is worth two points)
Dehydration on a magnitude of >2% body mass has been shown in the scientific literature to cause performance deficits. Performance deficits include areas such as aerobic and anaerobic capacity, strength, power and cognitive function, which are all crucial components in American football. Planned, individualized hydration plans minimize fluid losses and help maintain a state of dehydration (normal level of hydration). These hydration plans can be easily incorporated into American football practices and competitions to maximize performance and enhance overall safety. Consideration must be taken regarding the protective equipment worn by American football players and the potential extreme environmental conditions that they may be exposed to; these factors should be accounted for when developing appropriate hydration strategies for American football athletes. During intense exercise in the heat, the risk of dehydration and subsequent negative influences on performance and safety risks are increased due to the exacerbation of thermoregulatory and cardiovascular strain from the excessive losses in body water.
The overall injury rate in NCAA football is 8.1 injuries per 1,000 athlete exposures (games and practices combined). There were more than 41,000 injuries and 25 million athlete exposures from 2004 to 2009. Football players are nearly seven times more likely to be injured during a game than in practice. • Ligament sprains are the most common injury reported, accounting for more than 30 percent of all injuries, with the lateral ligaments of the ankle and medial collateral ligaments of the knee most commonly affected. Concussions make up 7.4 percent of all injuries in college football players. The preseason has the highest injury rate (9.7 per 1,000 athlete exposures) compared with in-season (7.5) and the postseason (4.2). (Note: does not include spring ball.) The greatest incidence for adverse events such as fatalities, heat illness and collapse is more often during transitions such as the first and second day of preseason and after a break period from practice.
