Sport

A sport is an activity that involves skill and physical exertion and that is governed by a generally accepted set of rules and guidelines. In most sports, there are competitions (games, races, and judged competitions such as gymnastics), with clear winners and losers as defined by the rules that govern the sports. For many people, competition, and a wish to develop and display one's skill and proficiency, are strong motives for engaging in sports. But many sports, such as running, swimming, and weightlifting, are often done non-competitively, merely to get exercise or for personal enjoyment.

As well as serving as a form of recreation for those engaged in the activity, sports are often a form of entertainment for far more spectators than participants, often run and promoted as a business. In professional sports leagues or associations, members of official teams or clubs are paid for their participation. Spectators, in turn, pay for admission to view the event at an arena, stadium, or other such venue, as well as broadcasting the event on television or radio often with commentary. Also, further revenues are generated through advertising and sponsorship of different aspects of the game: individual players, teams, competitions, and equipment. The Super Bowl in American football is a prime example: sponsorship of a thirty-second advertising slot during the game costs $2.6 million. There is also a phenomenon known as sports entertainment, such as professional wrestling, where the practices of sport are used to produce an entertaining show.

Types of sports

A sport may be either individual (as in running), group (e.g., two players may form a doubles team in tennis) or team (e.g., football). Individual sports, such as running and swimming, may feature teams, as at track meets, and team members may root for each other, but individuals do not directly help each others' individual scores, and the team scores are determined by individual performance. Group and team sports are very different in this regard: one player can directly help other player's ability to score, and so it is fully meaningful to speak only of the score that the entire team received.

Sports can also be divided into ball sports, races, fights, and demonstrations of skill. A great many sports, and most popular most spectator sports, are played with balls or ball-like objects: not just football in all varieties, but also baseball, basketball, tennis, golf, and hockey. These sports usually involve getting a ball through a relatively small target such as goal or hoop (an exception: baseball), and almost all are team sports (an exception: golf). Races include track and field events such as the 100-meter dash, long-distance running, swimming, cycling, and rowing. These sports usually involve moving a person (as in the marathon), or an object in which people are moving (as in luge), from a start line to a finish line, and the winner is determined by the fastest time. Fighting sports include boxing, martial arts such as karate, and wrestling, and are typically scored or based on how many "takedowns" a person scores. The best-known and most-watched demonstrations of skill and strength include figure skating, gymnastics, and weightlifting, but also include such diverse sports as surfing and rock climbing.

Games that do not require physical exertion are not usually referred to as sports. Chess and similar games of strategy sometimes are, and are reported on in Sports sections of newspapers. This is probably due to the fact that, insofar as they are interesting public competitions, they resemble the sports that are reported on in newspapers. Whether chess really ought to be called a sport is a matter about which intelligent people are capable of debating at great length.

A rather new kind of sport involves video games in single player mode, such as Dance Dance Revolution (a kind of game in which the player steps on an electronic carpet input device rhythmically) or multiplayer (computer) mode, such as StarCraft which is a very popular in South Korea competitions of which even show on their TV networks. The Wii gaming platform also involves some physical exertion.

Levels of competition

People participate in sports at many different levels of skill and formality. At one extreme are very informal sporting events, where the players come together for entertainment much more than for keen competition. In such sporting events, some rules may be relaxed or ignored.

At the other extreme is the world of professional sports. Players at the highest level of professional sport are frequently the best in the world. Furthermore, there is a tendency in many professional team sports for players to specialize by position, and extraordinary skill at an important position can earn a player a large salary. Though sports at the professional level are centered around the game, the game is subordinated in some respects to earning money for those who finance it-- through ticket sales, television broadcasting rights, as well as through merchandising.

Professional sports have had persistent problems with striking a balance between earning money and fostering competition. Different sports have handled this issue differently. In professional American football, for example, teams have a strict salary cap, and many have seen the high turnover in championship winners as a positive result. In other professional sports, such as baseball and professional soccer, particularly in Europe, owners have fewer restrictions on how to spend their money, and there is a tendency for the wealthiest teams to buy up all the talent and dominate their league.

Equipment and clothing

While many sports can be performed at an amateur level without specialist equipment, professional athletes often require rather extensive amounts of specialist equipment and clothing, and a great deal of research is conducted on how such equipment can improve performance, often by creating ever more technologically-advanced materials to make the equipment lighter or more resilient, and to make clothing that reduces friction or drag (for swimming, running, skiing or many other sports) or increase grip (as with running footwear). Much of this equipment is expensive, and athletes are often sponsored by sports equipment manufacturers. For many athletes, the advances of science and technology are now a strong component in boosting their performance.

There have been some ethical concerns with the use of technology in sports, but most athletes and sports organizations have decided that sports equipment and clothing are acceptable means of improving performance, while performance enhancing drugs are not.

Ethics and politics in sports

In the twentieth century, much controversy surrounded athletes who used their position to advocate for political causes. Many black American athletes took a vital role in advocating for civil rights, and used their athletic ability to change people's attitudes. Black American athletes Tommie Smith and John Carlos raising their gloved fists in a black power salute on the rostrum at the 1968 Olympic Games in Mexico City was one example of this, as were the athletic careers of Jesse Owens and Mohammed Ali. In the case of Smith and Carlos, there were negative repercussions with Avery Brundage expelling the athletes from the U.S. Olympic team and from the Olympic Village in Mexico City.

There has been a great deal of controversy in 2008 over the political reactions to the hosting of the Olympic Games in Beijing, China, with many people concerned about the human rights record of the Chinese government. During the torch-bearing ceremonies, numerous people attempted to extinguish while it passed through London and Paris. The British Olympic team were asked to sign a 'gag clause' that would prevent them from engaging in political speech during the Games, but they refused.

Sport has other ethical issues, many around the use of steroids and other drugs in doping. While banned by most sporting authorities, teams and leagues, doping is practiced with increasingly stealthy methods like blood doping being used. Many think that doping should be made legal, as to draw a distinction between, say, the use of a performance-enhancing swimsuit or shoe and the use of a drug is an artificial and unsustainable one, and that athletes also now use a variety of other methods to boost their performance, like high-altitude training and the use of oxygen tents. Supporters of doping bans argue that making doping legal would lead many athletes to feel compelled to use drugs to boost their performance - a dangerous and irresponsible move - and that lifting a ban on doping would mean that people are competing on the basis of who has the best doctors and drug laboratories rather than who has trained the hardest.

Some people have also raised questions about the short careers that many athletes have, with many players being unable to find employment after their sporting careers are finished. A great deal of time is spent discussing athletes responsibilities towards young people, as participants in a celebrity culture. In the United States where the National Collegiate Athletic Association system of sports in higher education operates, some university professors have argued that professional sports on campus detracts from the academic role of the university, with lower admissions requirements for student-athletes, with professors being pressured into giving better grades to student-athletes so that they don't lose their athletic scholarships, with the enormous pay given to sports coaches and other lines which academics feel are being crossed by the heavy focus on sports in universities.
