104-636: Dubai Sports is a 24/7 sports channel based in Dubai , United Arab Emirates . The channel started in 1998 to be the home for sports news around the country and was awarded the privilege of showing different sports events locally and worldwide. It is one of the channels of Dubai Media Incorporated . It used to broadcast as a FTA channel from the Hotbird 13 E satellite, so it was accessible in all Europe. It also used to be well known because it used to broadcast professional wrestling NWA-TNA pay per views for free with

208-492: A wage or salary ). Amateur participation in sport at lower levels is often called "grassroots sport". The popularity of spectator sport as a recreation for non-participants has led to sport becoming a major business in its own right, and this has incentivised a high paying professional sport culture, where high performing participants are rewarded with pay far in excess of average wages, which can run into millions of dollars. Some sports, or individual competitions within

312-693: A ball has crossed the goal line or not. The technology is not compulsory, but was used in the 2014 FIFA World Cup in Brazil, and the 2015 FIFA Women's World Cup in Canada, as well as in the Premier League from 2013–14 , and the Bundesliga from 2015–16 . In the NFL , a referee can ask for a review from the replay booth, or a head coach can issue a challenge to review the play using replays. The final decision rests with

416-461: A definition is provided by the Global Association of International Sports Federations (GAISF), which is the association for all the largest international sports federations (including association football , athletics , cycling , tennis , equestrian sports , and more), and is therefore the de facto representative of international sport. GAISF uses the following criteria, determining that

520-471: A disability have no equivalent in able-bodied sports. Masters sport , senior sport , or veteran sport is an age category of sport, that usually contains age groups of those 35 and older. It may concern unaltered or adapted sport activities, with and without competitions. Competitions The competition element of sport, along with the aesthetic appeal of some sports, result in the popularity of people attending to watch sport being played. This has led to

624-645: A key part of the ancient Olympic Games as well as the modern Olympics. The activity of running went through a period of widespread popularity in the United States during the running boom of the 1970s . Over the next two decades, as many as 25 million Americans were doing some form of running or jogging – accounting for roughly one tenth of the population. Today, road racing is a popular sport among non-professional athletes, who included over 7.7 million people in America alone in 2002. Footspeed , or sprint speed,

728-534: A line first. It can also be determined by judges who are scoring elements of the sporting performance, including objective or subjective measures such as technical performance or artistic impression. Records of performance are often kept, and for popular sports, this information may be widely announced or reported in sport news . Sport is also a major source of entertainment for non-participants, with spectator sport drawing large crowds to sport venues , and reaching wider audiences through broadcasting . Sport betting

832-453: A measured course over an established road (as opposed to track and cross country running ). These events normally range from distances of 5 kilometers to longer distances such as half marathons and marathons , and they may involve scores of runners or wheelchair entrants. Cross country running takes place over the open or rough terrain. The courses used for these events may include grass , mud , woodlands, hills, flat ground and water. It

936-440: A mid/forefoot strike may aid in propulsion. However, even among elite athletes, there are variations in self-selected footstrike types. This is especially true in longer distance events, where there is a prevalence of heel strikers. There does tend however to be a greater percentage of mid/forefoot striking runners in the elite fields, particularly in the faster racers and the winning individuals or groups. While one could attribute

1040-581: A regular sports season , followed in some cases by playoffs . Sport is generally recognised as system of activities based in physical athleticism or physical dexterity , with major competitions admitting only sports meeting this definition. Some organisations, such as the Council of Europe , preclude activities without any physical element from classification as sports. However, a number of competitive, but non-physical, activities claim recognition as mind sports . The International Olympic Committee who oversee

1144-409: A single person with others being done by hundreds. Most sports take place either in teams or competing as individuals. Some sports allow a "tie" or "draw", in which there is no single winner; others provide tie-breaking methods to ensure one winner. A number of contests may be arranged in a tournament format, producing a champion . Many sports leagues make an annual champion by arranging games in

1248-448: A slow increase in speed and distance. While running, it is best to pay attention to how one's body feels. If a runner is gasping for breath or feels exhausted while running, it may be beneficial to slow down or try a shorter distance for a few weeks. If a runner feels that the pace or distance is no longer challenging, then the runner may want to speed up or run farther. Running can also have psychological benefits, as many participants in

1352-769: A small number of mind sports, it is not open to admitting any further mind sports. There has been an increase in the application of the term "sport" to a wider set of non-physical challenges such as video games , also called esports (from "electronic sports"), especially due to the large scale of participation and organised competition, but these are not widely recognised by mainstream sports organisations. According to Council of Europe , European Sports Charter, article 2.i, " 'Sport' means all forms of physical activity which, through casual or organised participation, aim at expressing or improving physical fitness and mental well-being, forming social relationships or obtaining results in competition at all levels." There are opposing views on

1456-567: A sport should: They also recognise that sport can be primarily physical (such as rugby or athletics ), primarily mind (such as chess or Go ), predominantly motorised (such as Formula 1 or powerboating ), primarily co-ordination (such as snooker and other cue sports ), or primarily animal-supported (such as equestrian sport ). The inclusion of mind sports within sport definitions has not been universally accepted, leading to legal challenges from governing bodies in regards to being denied funding available to sports. Whilst GAISF recognises

1560-468: A sport, retain a policy of allowing only amateur sport . The Olympic Games started with a principle of amateur competition with those who practised a sport professionally considered to have an unfair advantage over those who practised it merely as a hobby. From 1971, Olympic athletes were allowed to receive compensation and sponsorship, and from 1986, the IOC decided to make all professional athletes eligible for

1664-417: A variety of speeds ranging from jogging to sprinting . Running in humans is associated with improved health and life expectancy . It is hypothesized that the ancestors of humankind developed the ability to run for long distances about 2.6 million years ago, probably to hunt animals . Competitive running grew out of religious festivals in various areas. Records of competitive racing date back to

Often competitive and organized , sports use, maintain, or improve physical ability and skills . They also provide enjoyment to participants and, in some cases, entertainment to spectators. Many sports exist, with different participant numbers, some are done by

1872-533: Is chafing , caused by repetitive rubbing of one piece of skin against another, or against an article of clothing. One common location for chafe to occur is the runner's upper thighs. The skin feels coarse and develops a rash-like look. A variety of deodorants and special anti-chafing creams are available to treat such problems. Chafe is also likely to occur on the nipple . There are a variety of home remedies that runners use to deal with chafing while running such as band-aids and using grease to reduce friction. Prevention

1976-429: Is a popular participatory sport and is one of the events which, along with track and field, road running, and racewalking , makes up the umbrella sport of athletics. The majority of popular races do not incorporate a significant change in elevation as a key component of a course. There are several, disparate variations that feature significant inclines or declines. These fall into two main groups. The naturalistic group

2080-437: Is a problem at some national and international sporting contests. Female participation in sports continues to rise alongside the opportunity for involvement and the value of sports for child development and physical fitness . Despite increases in female participation during the last three decades, a gap persists in the enrollment figures between male and female players in sports-related teams. Female players account for 39% of

2184-404: Is able to run a certain distance in the shortest time. Today, competitive running events make up the core of the sport of athletics . Events are usually grouped into several classes, each requiring substantially different athletic strengths and involving different tactics, training methods, and types of competitors. Running competitions have probably existed for most of humanity's history and were

2288-531: Is based on outdoor racing over geographical features. Among these are the cross country-related sports of fell running (a tradition associated with Northern Europe) and trail running (mainly ultramarathon distances), the running/climbing combination of skyrunning (organised by the International Skyrunning Federation with races across North America, Europe and East Asia) and the mainly trail- and road-centred mountain running (governed by

2392-512: Is common for popular sports to attract large broadcast audiences, leading to rival broadcasters bidding large amounts of money for the rights to show certain events. The football World Cup attracts a global television audience of hundreds of millions; the 2006 final alone attracted an estimated worldwide audience of well over 700 million and the 2011 Cricket World Cup Final attracted an estimated audience of 135 million in India alone. In

2496-421: Is commonly known to stretch before and after a workout session, and also avoid heavy equipment especially during the first couple of workout sessions. Also to help prevent shin splints do not increase the intensity of a workout more than 10% a week. To treat shin splints it is important to rest with the least amount of impact on your legs and apply ice to the area. A survey showed that shin splints make up 12.7% of

2600-483: Is in contrast to walking , where one foot is always in contact with the ground, the legs are kept mostly straight, and the center of gravity vaults over the stance leg or legs in an inverted pendulum fashion. A feature of a running body from the viewpoint of spring-mass mechanics is that changes in kinetic and potential energy within a stride co-occur, with energy storage accomplished by springy tendons and passive muscle elasticity. The term "running" can refer to

2704-456: Is in some cases severely regulated, and in others integral to the sport. According to A.T. Kearney , a consultancy, the global sporting industry is worth up to $ 620 billion as of 2013. The world's most accessible and practised sport is running , while association football is the most popular spectator sport. The word "sport" comes from the Old French desport meaning " leisure ", with

2808-490: Is key which is why form fitting clothes are important. An iliotibial band is a muscle and tendon that is attached to the hip and runs the length of the thigh to attach to the upper part of the tibia, and the band is what helps the knee to bend. This is an injury that is located at the knee and shows symptoms of swelling outside the knee. Iliotibial band syndrome is also known as "runner's knee" or "jogger's knee" because it can be caused by jogging or running. Once pain or swelling

2912-401: Is noticeable it is important to put ice on it immediately and it is recommended to rest the knee for better healing. Most knee injuries can be treated by light activity and much rest for the knee. In more serious cases, arthroscopy is the most common to help repair ligaments but severe situations reconstructive surgery would be needed. A survey was taken in 2011 with knee injuries being 22.7% of

3016-849: Is sunny and warm. Running can improve mental alertness and sleep. Both research and clinical experience have shown that exercise can be a treatment for serious depression and anxiety even some physicians prescribe exercise to most of their patients. Running can have a longer-lasting effect than anti-depressants. The non-threatening environment offered by running generates a sense of achievement and belonging which helps with mental illness. Many injuries are associated with running because of its high-impact nature. Change in running volume may lead to development of patellofemoral pain syndrome , iliotibial band syndrome , patellar tendinopathy , plica syndrome , and medial tibial stress syndrome . Change in running pace may cause Achilles tendinitis , gastrocnemius injuries, and plantar fasciitis . Repetitive stress on

3120-498: Is that the body adjusts to this flat surface running, and some of the muscles will become weaker, along with the added impact of running on a harder surface. Therefore, it can be beneficial to change terrain occasionally – such as trail, beach, or grass running. This is more unstable ground and allows the legs to strengthen different muscles. Runners should be wary of twisting their ankles on such terrain. Running downhill also increases knee stress and should, therefore, be avoided. Reducing

3224-789: Is the maximum speed at which a human can run. It is affected by many factors, varies greatly throughout the population, and is important in athletics and many sports. Air resistance for top sprinters can take up to 5% of their energy. The fastest human footspeed on record is 44.7 km/h (12.4 m/s; 27.8 mph), seen during a 100-meter sprint (average speed between the 60th and the 80th meter) by Usain Bolt . (see Category:Athletics (track and field) record progressions ) Track running events are individual or relay events with athletes racing over specified distances on an oval running track. The events are categorized as sprints , middle and long-distance , and hurdling . Road running takes place on

3328-476: Is used in most English dialects to describe the overall concept (e.g. "children taking part in sport"), with "sports" used to describe multiple activities (e.g. "football and rugby are the most popular sports in England"). American English uses "sports" for both terms. The precise definition of what differentiates a sport from other leisure activities varies between sources. The closest to an international agreement on

3432-805: The 1936 Summer Olympics held in Berlin , and the 1936 Winter Olympics held in Garmisch-Partenkirchen , to promote the Nazi ideology of the superiority of the Aryan race , and inferiority of the Jews and other " undesirables ". Germany used the Olympics to give off a peaceful image while secretly preparing for war. When apartheid was the official policy in South Africa, many sports people, particularly in rugby union , adopted

3536-603: The East African Rift in Africa. The Tailteann Games , an Irish sporting festival in honor of the goddess Tailtiu , dates back to 1829 BCE and is one of the earliest records of competitive running. The origins of the Olympics and Marathon running are shrouded by myth and legend, though the first recorded games took place in 776 BCE. Running in Ancient Greece can be traced back to these games of 776 BCE. ...I suspect that

3640-626: The Gaelic Athletic Association (GAA) if she/he played or supported Association football , or other games seen to be of British origin. Until recently the GAA continued to ban the playing of football and rugby union at Gaelic venues. This ban, also known as Rule 42, is still enforced, but was modified to allow football and rugby to be played in Croke Park while Lansdowne Road was redeveloped into Aviva Stadium . Until recently, under Rule 21,

3744-532: The Olympic Games recognises both chess and bridge as sports. SportAccord , the international sports federation association, recognises five non-physical sports: chess, bridge, draughts , Go and xiangqi . However, they limit the number of mind games which can be admitted as sports. Sport is usually governed by a set of rules or customs , which serve to ensure fair competition. Winning can be determined by physical events such as scoring goals or crossing

3848-570: The Tailteann Games in Ireland between 632 BCE and 1171 BCE, while the first recorded Olympic Games took place in 776 BCE. Running has been described as the world's most accessible sport. It is thought that human running evolved at least four and a half million years ago out of the ability of the ape-like Australopithecus , an early ancestor of humans, to walk upright on two legs . Early humans most likely developed into endurance runners from

3952-721: The immune system and an improved self-esteem and emotional state. Running, like all forms of regular exercise, can effectively slow or reverse the effects of aging. Even people who have already experienced a heart attack are 20% less likely to develop serious heart problems if more engaged in running or any type of aerobic activity. Although an optimal amount of vigorous aerobic exercise such as running might bring benefits related to lower cardiovascular disease and life extension, an excessive dose (e.g., marathons ) might have an opposite effect associated with cardiotoxicity . Running can assist people in losing weight, staying in shape and improving body composition. Research suggests that

4056-485: The war on drugs encourage youth sport as a means to increase educational participation and to fight the illegal drug trade . According to the Center for Injury Research and Policy at Nationwide Children's Hospital , the biggest risk for youth sport is death or serious injury including concussion . These risks come from running, basketball, association football, volleyball, gridiron, gymnastics, and ice hockey. Youth sport in

4160-640: The GAA also banned members of the British security forces and members of the RUC from playing Gaelic games, but the advent of the Good Friday Agreement in 1998 led to the eventual removal of the ban. Nationalism is often evident in the pursuit of sport, or in its reporting: people compete in national teams, or commentators and audiences can adopt a partisan view. On occasion, such tensions can lead to violent confrontation among players or spectators within and beyond

4264-523: The IOC or SportAccord are required to implement a testing programme, looking for a list of banned drugs, with suspensions or bans being placed on participants who test positive for banned substances. Violence in sports involves crossing the line between fair competition and intentional aggressive violence. Athletes, coaches, fans, and parents sometimes unleash violent behaviour on people or property, in misguided shows of loyalty, dominance, anger, or celebration. Rioting or hooliganism by fans in particular

4368-413: The Olympics, with the exceptions of boxing , and wrestling. Technology plays an important part in modern sport. It is a necessary part of some sports (such as motorsport), and it is used in others to improve performance. Some sports also use it to allow off-field decision making. Sports science is a widespread academic discipline, and can be applied to areas including athlete performance, such as

4472-515: The US is a $ 15 billion industry including equipment up to private coaching. Disabled or adaptive sports are played by people with a disability , including physical and intellectual disabilities . As many of these are based on existing sports modified to meet the needs of people with a disability, they are sometimes referred to as adapted sports . However, not all disabled sports are adapted; several sports that have been specifically created for people with

4576-563: The United States, the championship game of the NFL , the Super Bowl , has become one of the most watched television broadcasts of the year. Super Bowl Sunday is a de facto national holiday in America; the viewership being so great that in 2015, advertising space was reported as being sold at $ 4.5m for a 30-second slot. Sport can be undertaken on an amateur, professional or semi-professional basis, depending on whether participants are incentivised for participation (usually through payment of

4680-433: The absorption phases of running. The propulsion phase, which occurs from midstance to toe-off, is crucial for understanding how the body moves forward. In a full stride length model, elements of both the terminal swing and footstrike contribute to propulsion. The setup for propulsion begins at the end of the terminal swing when the hip joint flexes, allowing the hip extensors to generate force as they accelerate through

4784-790: The activity will be enjoyed for its own sake. The well-known sentiment by sports journalist Grantland Rice , that it is "not that you won or lost but how you played the game", and the modern Olympic creed expressed by its founder Pierre de Coubertin : "The most important thing... is not winning but taking part" are typical expressions of this sentiment. Key principles of sport include that the result should not be predetermined, and that both sides should have equal opportunity to win. Rules are in place to ensure fair play, but participants can break these rules in order to gain advantage. Participants may cheat in order to unfairly increase their chance of winning, or in order to achieve other advantages such as financial gains. The widespread existence of gambling on

4888-415: The ancient Olympics up to the present century. Industrialisation has brought motorised transportation and increased leisure time , letting people attend and follow spectator sports and participate in athletic activities. These trends continued with the advent of mass media and global communication. Professionalism became prevalent, further adding to the increase in sport's popularity, as sports fans followed

4992-410: The ankle joint. On the other hand, a mid/forefoot strike helps in shock absorption, supporting plantar flexion from midstance to toe-off. Actual propulsion begins as the lower extremity enters midstance. The hip extensors continue contracting, assisted by gravity and the stretch reflex from maximal hip flexion during the terminal swing. Hip extension pulls the ground underneath the body, propelling

5096-457: The ankle undergoes plantar flexion. Propulsion continues until the leg is extended behind the body and toe-off occurs. This involves a maximal hip extension, knee extension, and plantar flexion for the subject, resulting in the body being pushed forward from this motion, and the ankle/foot leaves the ground as the initial swing begins. Research, especially in the footstrike debate, has primarily focused on identifying and preventing injuries during

5200-452: The ball of the foot, ball and heel of the foot simultaneously and heel of the foot respectively. During this time, the hip joint is undergoing extension from being in maximal flexion from the previous swing phase. For proper force absorption, the knee joint should be flexed upon the footstrike, and the ankle should be slightly in front of the body. Footstrike begins the absorption phase as forces from initial contact are attenuated throughout

5304-447: The beginning of the initial swing of one side, there is a flight phase where neither extremity is in contact with the ground due to the opposite side finishing terminal swing. As the footstrike of the one hand occurs, the initial swing continues. The opposing limbs meet with one in midstance and midswing, beginning the propulsion and terminal swing phases. The upper extremity function serves mainly in providing balance in conjunction with

SECTION 50

5408-410: The body. Hip flexion and knee flexion occur, beginning the return of the limb to the starting position and setting up for another foot strike. The initial swing ends at midswing when the limb is again directly underneath the trunk, pelvis, and hip with the knee joint flexed and hip flexion continuing. Terminal swing then begins as hip flexion continues to the point of activation of the stretch reflex of

5512-432: The chin up and scrunching shoulders. Exercise physiologists have found that the stride rates are extremely consistent across professional runners, between 185 and 200 steps per minute. The main difference between long- and short-distance runners is the length of stride rather than the rate of stride. During running, the speed at which the runner moves may be calculated by multiplying the cadence (steps per minute) by

5616-467: The community in sports such as mass media campaigns, educational sessions, and policy changes. There is also no high-quality studies that investigate the effect of such interventions in promoting healthy behaviour change in the community. sports is one of the important part of life Benito Mussolini used the 1934 FIFA World Cup , which was held in Italy, to showcase Fascist Italy . Adolf Hitler also used

5720-483: The conscientious approach that they should not appear in competitive sports there. Some feel this was an effective contribution to the eventual demolition of the policy of apartheid, others feel that it may have prolonged and reinforced its worst effects. In the history of Ireland, Gaelic sports were connected with cultural nationalism . Until the mid-20th century a person could have been banned from playing Gaelic football , hurling , or other sports administered by

5824-450: The continuous nature of running gait, no certain point is assumed to be the beginning. However, for simplicity, it will be assumed that absorption and footstrike mark the beginning of the running cycle in a body already in motion. Footstrike occurs when a plantar portion of the foot makes initial contact with the ground. Common footstrike types include forefoot, midfoot, and heel strike types. These are characterized by initial contact of

5928-496: The differences in the potential injury risks and shock absorption capabilities between heel and mid/forefoot footstrikes. It has been shown that heel striking is generally associated with higher rates of injury and impact due to inefficient shock absorption and inefficient biomechanical compensations for these forces. This is due to pressures from a heel strike traveling through bones for shock absorption rather than being absorbed by muscles. Since bones cannot disperse forces easily,

6032-552: The end of the match time. Artifacts and structures suggest sport in China as early as 2000 BC. Gymnastics appears to have been popular in China's ancient past. Monuments to the Pharaohs indicate that a number of sports, including swimming and fishing, were well-developed and regulated several thousands of years ago in ancient Egypt . Other Egyptian sports included javelin throwing, high jump, and wrestling. Ancient Persian sports such as

6136-585: The exploits of professional athletes – all while enjoying the exercise and competition associated with amateur participation in sports. Since the turn of the 21st century, there has been increasing debate about whether transgender sports people should be able to participate in sport events that conform with their post-transition gender identity . Sportsmanship is an attitude that strives for fair play, courtesy toward teammates and opponents, ethical behaviour and integrity, and grace in victory or defeat. Sportsmanship expresses an aspiration or ethos that

6240-883: The faster speeds of elite runners compared to recreational runners with similar footstrikes to physiological differences, the hip, and joints have been left out of the equation for proper propulsion. This raises the question of how heel-striking elite distance runners can keep up such high paces with a supposedly inefficient and injurious foot strike technique. Biomechanical factors associated with elite runners include increased hip function, use, and stride length over recreational runners. An increase in running speeds causes increased ground reaction forces, and elite distance runners must compensate for this to maintain their pace over long distances. These forces are attenuated through increased stride length via increased hip flexion and extension through decreased ground contact time and more energy being used in propulsion. With increased propulsion in

6344-439: The forces are transmitted to other parts of the body, including ligaments, joints, and bones in the rest of the lower extremities up to the lower back. This causes the body to use abnormal compensatory motions in an attempt to avoid serious bone injuries. These compensations include internal rotation of the tibia, knee, and hip joints. Excessive compensation over time has been linked to a higher risk of injuries in those joints and

SECTION 60

6448-433: The frequency and duration can also prevent injury. Barefoot running has been promoted as a means of reducing running related injuries, but this remains controversial and a majority of professionals advocate the wearing of appropriate shoes as the best method for avoiding injury. However, a study in 2013 concluded that wearing neutral shoes is not associated with increased injuries. Another common, running-related injury

6552-404: The ground, returning from dorsiflexion in midstance. This can occur either by releasing the elastic load from an earlier mid/forefoot strike or through concentric contraction from a heel strike. With a forefoot strike, the ankle and knee joints release their stored elastic energy from the footstrike/absorption phase. The quadriceps group/knee extensors fully extend the knee, pushing the body off

6656-409: The ground. Simultaneously, the knee flexors and stretch reflex pull the knee back into flexion, initiating the initial swing phase. The hip extensors extend to the maximum, contributing to forces pulling and pushing off the ground, as well as initiating knee flexion and the initial swing phase. Initial swing is the response of both stretch reflexes and concentric movements to the propulsion movements of

6760-469: The heel and facilitates the use of the spring mechanism of the foot. Additionally, it facilitates avoiding the braking effect that occurs when a runner lands their foot in front of the center of mass. Although maintaining an upright posture is crucial, runners should also keep their frame relaxed and engage their core to keep their posture stable. This helps prevent injury as long as the body is neither rigid nor tense. The most common running mistakes are tilting

6864-435: The hip extensors. The knee begins to extend slightly as it swings to the anterior portion of the body. The foot then makes contact with the ground with a foot strike, completing the running cycle of one side of the lower extremity. Each limb of the lower extremity works opposite to the other. When one side is in toe-off/propulsion, the other hand is in the swing/recovery phase preparing for footstrike. Following toe-off and

6968-403: The horizontal plane, less impact occurs from the decreased force in the vertical plane. Increased hip flexion allows for increased use of the hip extensors through midstance and toe-off, allowing for more force production. The difference even between world-class and national-level 1500-m runners has been associated with more efficient hip joint function. The increase in velocity likely comes from

7072-414: The host broadcaster, a number of different technologies are used during an umpire or player review, including instant replays, Hawk-Eye , Hot Spot and Real Time Snickometer . Hawk-Eye is also used in tennis to challenge umpiring decisions. Research suggests that sports have the capacity to connect youth to positive adult role models and provide positive development opportunities, as well as promote

7176-427: The impact of losing on less able participants, there has been an introduction of non-competitive physical activity to traditionally competitive events such as school sports days , although moves like this are often controversial. In competitive events, participants are graded or classified based on their "result" and often divided into groups of comparable performance, (e.g. gender, weight and age). The measurement of

7280-509: The impact of technical advantage between participants. For example, in 2010, full-body, non-textile swimsuits were banned by FINA , as they were enhancing swimmers' performances. The increase in technology has also allowed many decisions in sports matches to be taken, or reviewed, off-field, with another official using instant replays to make decisions. In some sports, players can now challenge decisions made by officials. In Association football , goal-line technology makes decisions on whether

7384-679: The increased range of motion in hip flexion and extension, allowing for greater acceleration and speed. The hip extensors and extension have been linked to more powerful knee extension during toe-off, contributing to propulsion. Stride length must be appropriately increased with some degree of knee flexion maintained through the terminal swing phases, as excessive knee extension during this phase along with footstrike has been associated with higher impact forces due to braking and an increased prevalence of heel striking. Elite runners tend to exhibit some degree of knee flexion at footstrike and midstance, which first serves to eccentrically absorb impact forces in

7488-521: The incumbent president is more likely to win, and if the Redskins lose, then the opposition candidate is more likely to win; this has become known as the Redskins Rule . Running Running is a method of terrestrial locomotion by which humans and other animals move rapidly on foot. Running is a gait with an aerial phase in which all feet are above the ground (though there are exceptions). This

7592-431: The learning and application of life skills . In recent years the use of sport to reduce crime , as well as to prevent violent extremism and radicalization , has become more widespread, especially as a tool to improve self-esteem , enhance social bonds and provide participants with a feeling of purpose. There is no high-quality evidence that shows the effectiveness of interventions to increase sports participation of

7696-412: The lower extremity. Absorption of forces continues as the body moves from footstrike to midstance due to vertical propulsion from the toe-off during a previous gait cycle. Midstance is when the lower extremity limb of focus is in knee flexion directly underneath the trunk, pelvis, and hips. At this point, propulsion begins to occur as the hips undergo hip extension, the knee joint undergoes extension, and

7800-450: The maximal range of motion. As the hip extensors transition from inhibitory to primary muscle movers, the lower extremity moves back towards the ground, aided by the stretch reflex and gravity. The footstrike and absorption phases follow, leading to two possible outcomes. With a heel strike, this phase may be just a continuation of momentum from the stretch reflex, gravity, and light hip extension, offering little force absorption through

7904-409: The most common injuries in running, with blisters being the top percentage at 30.9%. Running is both a competition and a type of training for sports that have running or endurance components. As a sport, it is split into events divided by distance and sometimes includes permutations such as the obstacles in steeplechase and hurdles . Running races are contests to determine which of the competitors

8008-456: The most common injuries. A more known injury is medial tibial stress syndrome (MTSS) which is the accurate name for shin splints. This is caused during running when the muscle is being overused along the front of the lower leg with symptoms that affect 2 to 6 inches of the muscle. Shin splints have sharp, splinter-like pain, that is typically X-rayed by doctors but is not necessary for shin splints to be diagnosed. To help prevent shin splints it

8112-492: The muscles involved in those motions. Conversely, a mid/forefoot strike has been associated with greater efficiency and lower injury risk due to the triceps surae being used as a lever system to absorb forces with the muscles eccentrically rather than through the bone. Landing with a mid/forefoot strike has also been shown to properly attenuate shock and allow the triceps surae to aid in propulsion via reflexive plantarflexion after stretching to absorb ground contact forces. Thus

8216-610: The natural habits of animals when running, indicating the likelihood of this activity as a successful hunting method. Further evidence from observation of modern-day hunting practices also indicated this likelihood (Carrier et al. 1984). According to Sears (p. 12) scientific investigation (Walker & Leakey 1993) of the Nariokotome skeleton provided further evidence for the Carrier theory. Competitive running grew out of religious festivals in various areas such as Greece, Egypt, Asia, and

8320-586: The necessity of competition as a defining element of a sport, with almost all professional sports involving competition, and governing bodies requiring competition as a prerequisite of recognition by the International Olympic Committee (IOC) or GAISF. Other bodies advocate widening the definition of sport to include all physical activity. For instance, the Council of Europe include all forms of physical exercise, including those competed just for fun. In order to widen participation, and reduce

8424-493: The number of newly created neurons within the brain. This finding could have significant implications in aging as well as learning and memory. A recent study published in Cell Metabolism has also linked running with improved memory and learning skills. Running is an effective way to reduce stress, anxiety, depression, and inflammation. It helps people who struggle with seasonal affective disorder by running outside when it

8528-476: The oldest definition in English from around 1300 being "anything humans find amusing or entertaining". Other meanings include gambling and events staged for the purpose of gambling; hunting; and games and diversions, including ones that require exercise. Roget's defines the noun sport as an "activity engaged in for relaxation and amusement" with synonyms including diversion and recreation. The singular term "sport"

8632-469: The opposing side of the lower extremity. The movement of each leg is paired with the opposite arm, which serves to counterbalance the body, particularly during the stance phase. The arms move most effectively (as seen in elite athletes) with the elbow joint at approximately 90 degrees or less, the hands swinging from the hips up to mid-chest level with the opposite leg, the Humerus moving from being parallel with

8736-404: The person of average weight will burn approximately 100 calories per mile run. Running increases one's metabolism , even after running; one will continue to burn an increased level of calories for a short time after the run. Different speeds and distances are appropriate for different individual health and fitness levels. For new runners, it takes time to get into shape. The key is consistency and

8840-426: The potential for injury while running (just as there is in any sport), there are many benefits. Some of these benefits include potential weight loss , improved cardiovascular and respiratory health (reducing the risk of cardiovascular and respiratory diseases), improved cardiovascular fitness, reduced total blood cholesterol , strengthening of bones (and potentially increased bone density), possible strengthening of

8944-536: The practice of persistence hunting of animals, the activity of following and chasing until a prey is too exhausted to flee, succumbing to "chase myopathy " (Sears 2001), and that human features such as the nuchal ligament , abundant sweat glands , the Achilles tendons , big knee joints and muscular glutei maximi , were changes caused by this type of activity (Bramble & Lieberman 2004, et al.). The theory as first proposed used comparative physiological evidence and

9048-459: The quadriceps muscle group. Secondly it allows for the knee joint to contract concentrically and provides significant aid in propulsion during toe-off as the quadriceps group is capable of producing large amounts of force. Recreational runners have been shown to increase stride length through increased knee extension rather than increased hip flexion, as exhibited by elite runners, which provides an intense braking motion with each step and decreases

9152-407: The rate and efficiency of knee extension during toe-off, slowing down speed. Knee extension, however, contributes to additional stride length and propulsion during toe-off and is seen more frequently in elite runners as well. ‹The template How-to is being considered for merging .›   Leaning forward places a runner's center of mass on the front part of the foot, which avoids landing on

9256-565: The referee. A video referee (commonly known as a Television Match Official or TMO) can also use replays to help decision-making in rugby (both league and union ). In international cricket, an umpire can ask the Third umpire for a decision, and the third umpire makes the final decision. Since 2008, a decision review system for players to review decisions has been introduced and used in ICC -run tournaments, and optionally in other matches. Depending on

9360-412: The result may be objective or subjective, and corrected with "handicaps" or penalties. In a race, for example, the time to complete the course is an objective measurement. In gymnastics or diving the result is decided by a panel of judges, and therefore subjective. There are many shades of judging between boxing and mixed martial arts, where victory is assigned by judges if neither competitor has lost at

9464-582: The result of sports events can affect the results. A study published in the Proceedings of the National Academy of Sciences showed that when the home team wins the game before the election, the incumbent candidates can increase their share of the vote by 1.5 per cent. A loss had the opposite effect, and the effect is greater for higher-profile teams or unexpected wins and losses. Also, when Washington Redskins win their final game before an election, then

9568-450: The results of sports events creates a motivation for match fixing , where a participant or participants deliberately work to ensure a given outcome rather than simply playing to win. The competitive nature of sport encourages some participants to attempt to enhance their performance through the use of medicines, or through other means such as increasing the volume of blood in their bodies through artificial means . All sports recognised by

9672-468: The runner forward. During midstance, the knee should be slightly flexed due to elastic loading from the absorption and footstrike phases, preserving forward momentum. The ankle joint is in dorsiflexion at this point, either elastically loaded from a mid/forefoot strike or preparing for stand-alone concentric plantar flexion. The final propulsive movements during toe-off involve all three joints: ankle, knee, and hip. The plantar flexors push off from

9776-503: The same tissues without enough time for recovery or running with improper form can lead to many of the above. Runners generally attempt to minimize these injuries by warming up before exercise, focusing on proper running form, performing strength training exercises, eating a well balanced diet, allowing time for recovery, and "icing" (applying ice to sore muscles or taking an ice bath). Some runners may experience injuries when running on concrete surfaces. The problem with running on concrete

9880-558: The specific phenomenon of spectator sport. Both amateur and professional sports attract spectators, both in person at the sport venue, and through broadcast media including radio , television and internet broadcast. Both attendance in person and viewing remotely can incur a sometimes substantial charge, such as an entrance ticket, or pay-per-view television broadcast. Sports league and tournament are two common arrangements to organise sport teams or individual athletes into competing against each other continuously or periodically. It

9984-418: The sport report feeling an elated, euphoric state, often referred to as a " runner's high ". Running is frequently recommended as therapy for people with clinical depression and people coping with addiction. A possible benefit may be the enjoyment of nature and scenery, which also improves psychological well-being (see Ecopsychology § Practical benefits ). In animal models, running has been shown to increase

10088-637: The sporting venue, as in the Football War . These trends are seen by many as contrary to the fundamental ethos of sport being carried on for its own sake and for the enjoyment of its participants. Sport and politics collided in the 1972 Olympics in Munich. Masked men entered the hotel of the Israeli Olympic team and killed many of their men. This was known as the Munich massacre . A study of US elections has shown that

10192-578: The stride length. Running is often measured in terms of pace , expressed in units of minutes per mile or minutes per kilometer (the inverse of speed, in mph or km/h). Some coaches advocate training at a combination of specific paces related to one's fitness to stimulate various physiological improvements. Different types of stride are necessary for different types of running. When sprinting, runners stay on their toes bringing their legs up, using shorter and faster strides. Long-distance runners tend to have more relaxed strides that vary. While there exists

10296-467: The sun, moon, earth, stars, and heaven, which are still the gods of many barbarians, were the only gods known to the aboriginal Hellenes. Seeing that they were always moving and running, from their running nature they were called gods or runners (Thus, Theontas)... Running gait can be divided into two phases regarding the lower extremity : stance and swing. These can be further divided into absorption, propulsion, initial swing, and terminal swing. Due to

10400-561: The time of Ancient Greece and the military culture and the development of sport in Greece influenced one another considerably. Sport became such a prominent part of their culture that the Greeks created the Olympic Games , which in ancient times were held every four years in a small village in the Peloponnesus called Olympia . Sports have been increasingly organised and regulated from the time of

10504-465: The total participation in US interscholastic athletics. Certain sports are mixed-gender , allowing (or even requiring) men and women to play on the same team. One example of this is Baseball5 , which is the first mixed-gender sport to have been admitted into an Olympic event. Youth sport presents children with opportunities for fun, socialisation, forming peer relationships, physical fitness , and athletic scholarships . Activists for education and

10608-403: The traditional Iranian martial art of Zoorkhaneh had a close connection to warfare skills. Among other sports that originated in ancient Persia are polo and jousting . Various traditional games of India such as Kho kho and Kabbadi have been played for thousands of years. The kabaddi was played potentially as a preparation for hunting. A wide range of sports were already established by

10712-520: The trunk to approximately 45 degrees shoulder extension (never passing the trunk in flexion) and with as little movement in the transverse plane as possible. The trunk also rotates in conjunction with arm swing. It mainly serves as a balance point from which the limbs are anchored. Thus trunk motion should remain mostly stable with little motion except for slight rotation, as excessive movement would contribute to transverse motion and wasted energy. Recent research into various forms of running has focused on

10816-460: The use of video analysis to fine-tune technique, or to equipment, such as improved running shoes or competitive swimwear . Sports engineering emerged as a discipline in 1998 with an increasing focus not just on materials design but also the use of technology in sport, from analytics and big data to wearable technology . In order to control the impact of technology on fair play, governing bodies frequently have specific rules that are set to control
