American football is a sport evolved from rugby and is one of the most popular team sports in North America nowadays. It is a sport that has a high pace and high intensity, together with lots of body contact. Therefore, the risk of injury in this sport is higher than other sports in general. Due to the special features of this sport, the physiological demands of football players worth our concern as the physiological conditions of football players have a significant influence on their performance and also their chance of injury (Pincivero & Bompa, 1997). In this essay, the physiological demands of being a highly competitive football player will be discussed.

As mentioned before, football is a fast-paced and highly intensive sport with a great amount of body contacts. Muscular power is vital in blocking, tackling, as well as sprinting. Also, the duration of a match range from 48 to 60 minutes. Therefore, the players’ muscles have to endure lots of impacts and energy consumption during every game. Unlike other sports such as basketball and soccer, the game of American football consists of separate rounds of plays. Along with unlimited number of player substitutions, there is time for players to rest and recover between each play (Pincivero & Bompa, 1997). The endurance of their muscles and the rate of recovery for the players are crucial to sustain the standard of their …show more content…

Vural, Nalçakan & Özkol (2009) suggested that offensive line and defensive line players tend to be heavier and have a higher percentage of body fat when compared with other positions such as wide receivers due to their main duties, which are blocking and tackling. To be a highly competitive offensive line or defensive line players, one may have to be heavier and have a relatively higher percentage of body fat, so as to gain advantage in blocking and tackling. In contrast, a highly competitive wide receiver should be lighter and possess lower percentage of body fat in order to sprint

  • Main Energy Systems Used in a Game of Touch Football

    884 Words  | 2 Pages

    There are three main energy systems used in a game of touch football which consist of the creatine phosphate (ATP PC) system, lactic acid system and the aerobic system. Each system plays a vital role during game play. Every muscle in your body requires energy to perform all movements, and to do this, the energy is produced by the breakdown of a molecule called adenosine triphosphate (ATP). ATP is found in all cells which is a chemical form of muscular activity and performs mostly all functions in the human body. It contains 3 phosphate groups and adenosine. ATP is stored in the muscles and lasts for approximately 10-30 seconds. Carbohydrates, fats and proteins, are all producers of ATP from the food we eat; however Creatine Phosphate is also a high energy compound producer found in the cells. These three chemical reactions are conducted to continue muscular work. The first system used in a game of touch football is the ATP PC system. This system is stored into the muscles and used in short durations for up to 10 seconds and doesn’t not require oxygen therefore being anaerobic. ATP lasts approximately 3 seconds, and then Creatine phosphate (CP) will continue until all ATP PC energy is used up. The use of ATP is high intensity and would usually be used in a 50m sprint or a pass in touch. Once the CP energy is used up the body then switches to the lactic acid system. This is because of the breakdown of glucose, resulting in the production of lactic acid. The lactic acid system an anaerobic energy system, which lasts for approximately 30 seconds to 2 minutes, and is the conversion of glycogen to glucose. In relation to a game of touch football, the lactic acid system could be used during a quick wruck, as the movements required are a...

    Since football’s inception, it has been considered a manly sport. Young boys have been encouraged by their parents to participate in the game. For many boys, it is considered a rite of passage. However, football is a dangerous sport. A study conducted by the Center for Injury Research and Policy found, “an estimated 5.25 million football-related injuries among children and adolescents between 6 and 17 years of age were treated in U.S. emergency departments between 1990 and 2007. The annual number of football-related injuries increased 27 percent during the 18-year study period, jumping from 274,094 in 1990 to 346,772 in 2007” (Nation 201). These reported injuries include sprains and strains, broken bones, cracked ribs, torn ligaments, and concussions. A concussion usually happens when a player takes a hard hit to the head or is knocked unconscious on the playing field, and if not diagnosed and treated quickly, a concussion can result in death.

    Basketball is a "transition game. Players continuously switch between defensive and offensive plays throughout the game. The plays include strenuous physical, such as running/sprinting, cutting, feints, jumps, and landings. Rapid turns and proximity during one-on-one situations increase the possibility of physical contact. Thus, frequent intermittent running and sprinting characterize the action of the game. Motion analysis has shown that depending on individual playing-time; basketball players cover a distance between 4.6 and 5.8 km per game, with mean heart rates between 80 and 90% of individual maximum heart rates (European Network for Sports injuries prevention, 2008). Consequently, players need to rid of highly advanced basic...

    Besides the mechanism of an injury, injuries can be distinguished by their severity. Injury severity can be defined by whether or not the athlete lost participation time (Yang et al., 2012). The National Athletic Injury/Illness Reporting Systems (NAIRS) better differentiates injury severity by classifying injuries as either time-loss (TL) or non-time-loss (NTL) injuries. Injuries that required an athlete to miss the next scheduled event/session were identified as TL injuries, while injuries that did not restrict an athlete’s ability to play we...

Overtraining is defined as the accumulation of both training and non-training stresses producing a long-term effect on the athlete’s performance capacity, with or without physical and psychological overtraining signs and symptoms in which recovery of the performance capacity will take weeks to months (Halson, 2004 p. 969).
