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

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,

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

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

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

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

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 .

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

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

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

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

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

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

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,

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

#17328528037016448-433: 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

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

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
