Helmet-to-helmet Collision
Helmet-to-helmet collisions are occurrences in gridiron football when two players' football helmets make head-to-head contact with a high degree of force. Intentionally causing a helmet-to-helmet collision is a penalty in most football leagues, including many high school leagues. Despite its long association with American football, this type of contact is now considered to be dangerous play by league authorities due to the potential of causing serious injury. Major football leagues, such as the National Football League (NFL), Canadian Football League (CFL), and NCAA, have taken a tougher stance on helmet-to-helmet collisions after the US Congress launched an investigation into the effects repeated concussions have on football players and the new discoveries of chronic traumatic encephalopathy (CTE). Other possible injuries include head traumas, spinal cord injuries, and even death. Helmet manufacturers are constantly improving their designs in order to best protect their users ag ...

Chronic Traumatic Encephalopathy
Chronic traumatic encephalopathy (CTE) is a neurodegenerative disease linked to repeated trauma to the head. The encephalopathy symptoms can include behavioral problems, mood problems, and problems with thinking. The disease often gets worse over time and can result in dementia. It is unclear if the risk of suicide is altered. Most documented cases have occurred in athletes involved in striking-based combat sports, such as boxing, kickboxing, mixed martial arts, and Muay Thai—hence its original name ''dementia pugilistica'' (Latin for "fistfighter's dementia")—and contact sports such as American football, Australian rules football, professional wrestling, ice hockey, rugby, and association football (soccer), in semi-contact sports such as baseball and basketball, and military combat arms occupations. Other risk factors include being in the military, prior domestic violence, and repeated banging of the head. The exact amount of trauma required for the condition to occur i ...

New Orleans Saints Bounty Scandal
The New Orleans Saints bounty scandal, formally known as "Bountygate," was an incident in which members of the New Orleans Saints team of the National Football League (NFL) were accused of paying out bonuses, or " bounties," for injuring opposing team players. The pool was alleged to have been in operation from 2009 (the year in which the Saints won Super Bowl XLIV) to 2011. League commissioner Roger Goodell responded with some of the most severe sanctions in the league's 92-year history, and among the most severe punishments for in-game misconduct in North American professional sports history. Defensive coordinator Gregg Williams was suspended indefinitely, though this would be overturned the following year. Head coach Sean Payton was suspended for the entire 2012 season—the first time since Chuck Fairbanks in 1978 that a head coach had been suspended. General manager Mickey Loomis was suspended for the first eight games of the 2012 season. Assistant head coach Joe Vitt wa ...

Bounty Bowl
The Bounty Bowl was the name given to two National Football League, NFL games held in 1989 NFL season, 1989 between the 1989 Philadelphia Eagles season, Philadelphia Eagles and 1989 Dallas Cowboys season, Dallas Cowboys. The first, a 1989 NFL season, 1989 NFL on Thanksgiving Day, Thanksgiving Day game in Texas Stadium, Dallas, was noted for allegations that the Eagles put a $200 bounty (reward), bounty on Cowboys placekicker, kicker Luis Zendejas, who had been cut by Philadelphia earlier that season. The second was a rematch held two weeks later in Philadelphia. The Eagles, who were heavy favorites to win both games, swept the series. Bounty Bowl I: The 1989 Thanksgiving Classic The Cowboys/Eagles rivalry had been increasingly heated since the 1986 season, with Buddy Ryan arriving as the Eagles' head coach; the next year, during the NFL players' strike, the Cowboys (who were playing with a number of players that crossed picket lines) routed an Eagles squad filled with replacement ...

Impact Monitor
A shock detector, shock indicator, or impact monitor is a device which indicates whether a physical shock or impact has occurred. These usually have a binary output (go/no-go) and are sometimes called ''shock overload devices''. Shock detectors can be used on shipments of fragile valuable items to indicate whether a potentially damaging drop or impact may have occurred. They are also used in sports helmets to help estimate if a dangerous impact may have occurred.Harris, C. M., and Peirsol, A. G. "Shock and Vibration Handbook", 2001, McGraw Hill, ISBN 0-07-137081-1 By contrast, a shock data logger is a data acquisition system for analysis and recording of shock pulses. Overview Shocks and impacts are often specified by the peak acceleration expressed in g-s (sometimes called g-forces). The form of the shock pulse and particularly the duration are equally important. For example, a short 1 ms 300 g shock has little damage potential and is not usually of interest but a 20 ms 3 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Helmet Removal (sports)
In organized athletics, few situations give rise to greater anxiety than the 'downed athlete'. Obvious causes include head and neck injury, or both, with no immediate means of excluding neck injury in the athlete who may be unable to give a history. Compounding the problem is the potential for the athlete's airway being compromised. Such a situation requires effective triage with the possibility of the athlete's injury being worsened or its effects being made permanent, if the initial steps taken are not appropriate. Paradoxically, the equipment designed to prevent or mitigate injury, such as helmets, face masks, neck rolls, and shoulder pads, contributes to the complexity of the steps needed to be taken. Finally, environmental challenges, such as the difficulty of first responders moving on an ice arena, or maneuvering an ambulance through inadequate access routes, will add to the problem if not previously addressed by inspection of facilities and, in the best circumstances, ...

Health Issues In American Football
Health issues in American football comprise a large number of health risks associated with participating in the sport. Injuries are relatively common in American football, due to its nature as a full-contact game. Injuries occur during both practice and games. Several factors can affect the frequency of injuries: epidemiological studies have shown older players can be at a greater risk, while equipment and experienced coaches can reduce the risk of injury. Common injuries include strains, sprains, fractures, dislocations, and concussions. Concussions have become a concern, as they increase the risk of mental illnesses like dementia and chronic traumatic encephalopathy (CTE). In individual leagues like the National Football League (NFL) and National Collegiate Athletic Association (NCAA), a public injury report is published containing all injured players on a team, their injury and the game-day status of each player. Catastrophic injuries—defined as serious injury to the spin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Concussions In Sport
Concussions, a type of mild traumatic brain injury, are a frequent concern for those playing sports, from children and teenagers to professional athletes. Repeated concussions are a known cause of various neurological disorders, most notably chronic traumatic encephalopathy (CTE), which in professional athletes has led to premature retirement, erratic behavior and even suicide. A sports-related concussion is currently defined as a "complex pathophysiological process affecting the brain, induced by biomechanical forces". Because concussions cannot be seen on X-rays or CT scans, attempts to prevent concussions have been difficult. The dangers of repeated concussions have long been known for boxing, boxers and wrestling, wrestlers; a form of CTE common in these two sports, dementia pugilistica (DP), was first described in 1928. An awareness of the risks of concussions in other sports began to grow in the 1990s, and especially in the mid-2000s, in both the medical and the professiona ...

Concussions In American Football
Concussions and play-related head blows in American football have been shown to be the cause of chronic traumatic encephalopathy (CTE), which has led to player deaths and other debilitating symptoms after retirement, including memory loss, depression, anxiety, headaches, stress, and sleep disturbances. The list of ex-NFL players that have either been diagnosed ''post-mortem'' with CTE or have reported symptoms of CTE continues to grow. According to Boston University, CTE is a brain degenerative disease found in athletes, military veterans, and others with history of repetitive brain trauma. Although CTE is highly controversial and misunderstood, it is believed that a protein called Tau forms clumps that slowly spread throughout the brain, killing brain cells. There is also theoretical research that suggests early CTE might result from damaged blood vessels within the brain. That could trigger brain inflammation and, eventually, the development of proteins such as Tau believed t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
