Introduction to Athletic Gear

Athletes count their gear--from clothing to accessories--as an important part of their respective sports. Athletic gear enhances the athlete in a myriad of ways, from performance to looks. As such, professional athletes and sports aficionados alike invest in their gear. Also, ordinary, non-athlete people use athletic gear in their casual attire, making these clothing and equipment fashion pieces as well.

Athletic trainers

Athletic trainers help prevent and treat injuries for people of all ages. Their clients include everyone from professional athletes to industrial workers. Recognized by the American Medical Association as allied health professionals, athletic trainers specialize in the prevention, assessment, treatment, and rehabilitation of musculoskeletal injuries. Athletic trainers often are one of the first heath care providers on the scene when injuries occur, and therefore they must be able to recognize, evaluate, and assess injuries and provide immediate care when needed. They also are heavily involved in the rehabilitation and reconditioning of injuries. Athletic trainers should not be confused with fitness trainers or personal trainers, who are not health care workers, but rather train people to become physically fit.

Athletic trainers often help prevent injuries by advising on the proper use of equipment and applying protective or injury-preventive devices such as tape, bandages, and braces. Injury prevention also often includes educating people on what they should do to avoid putting themselves at risk for injuries.

Athletic trainers work under the supervision of a licensed physician, and in cooperation with other health care providers. The level of medical supervision varies, depending upon the setting. Some athletic trainers meet with the team physician or consulting physician once or twice a week; others interact with a physician every day. The extent of the supervision ranges from discussing specific injuries and treatment options with a physician to performing evaluations and treatments as directed by a physician.

Athletic trainers often have administrative responsibilities. These may include regular meetings with an athletic director or other administrative officer to deal with budgets, purchasing, policy implementation, and other business-related issues.

Work environment. The work of athletic trainers requires frequent interaction with others. This includes consulting with physicians as well as frequent contact with athletes and patients to discuss and administer treatments, rehabilitation programs, injury-preventive practices, and other health-related issues. Many athletic trainers work indoors most of the time; others, especially those in some sports-related jobs, spend much of their time working outdoors. The job also might require standing for long periods, working with medical equipment or machinery, and being able to walk, run, kneel, crouch, stoop, or crawl. Travel may be required.

Schedules vary by work setting. Athletic trainers in nonsports settings generally have an established schedule—usually about 40 to 50 hours per week—with nights and weekends off. Athletic trainers working in hospitals and clinics may spend part of their time working at other locations doing outreach. Most commonly, these outreach programs include conducting athletic training services and speaking at high schools, colleges, and commercial businesses.

Athletic trainers in sports settings have schedules that are longer and more variable. These athletic trainers must be present for team practices and games, which often are on evenings and weekends, and their schedules can change on short notice when games and practices have to be rescheduled. As a result, athletic trainers in sports settings may regularly work 6 or 7 days per week, including late hours.

In high schools, athletic trainers who also teach may work 60 to 70 hours a week, or more. In National Collegiate Athletic Association Division I colleges and universities, athletic trainers generally work with one team; when that team’s sport is in season, working at least 50 to 60 hours a week is common. Athletic trainers in smaller colleges and universities often work with several teams and have teaching responsibilities. During the off-season, a 40-hour to 50-hour work week may be normal in most settings. Athletic trainers for professional sports teams generally work the most hours per week. During training camps, practices, and competitions, they may be required to work up to 12 hours a day.

There is some stress involved with being an athletic trainer, as there is with most health-related occupations. Athletic trainers are responsible for their clients’ health, and sometimes have to make quick decisions that could affect the health or career of their clients. Athletics trainers also can be affected by the pressure to win that is typical of competitive sports teams.

Racing flats

Racing flats or simply flats, are lightweight athletic shoes designed for long distance track and field, cross country, and most often - road races. They differ from normal training shoes mainly by the lack of a substantial heel (hence the name). They are also a great deal less durable and typically last half to a quarter of the distance of a normal training shoe (125-250 miles or 200-400 kilometers). The removal of the heel in racing flats has 4 principal effects: weight reduction, better foot to ground power transfer, providing less support and giving less cushioning. These features allow a runner to race more efficiently.

2008 Summer Olympics

The 2008 Summer Olympic Games, officially known as the Games of the XXIX Olympiad, was a major international multi-sport event that took place in Beijing, People's Republic of China, from August 8 (except football, which started on August 6) to August 24, 2008. A total of 10,500 athletes competed in 302 events in 28 sports, one event more than was on the schedule of the 2004 Games. The 2008 Beijing Olympics marked the first occasion that either the Summer or Winter Games were hosted in China, making it the 22nd nation to do so. It also became the third time that Olympic events have been held in the territories of two different National Olympic Committees (NOC), as the equestrian events were being held in Hong Kong (the other two instances being the 1956 games, where the equestrian events were hosted in Stockholm, Sweden, due to strict Australian quarantine rules, and the other events were hosted in Melbourne, Australia; and the 1920 games which were hosted in Antwerp, Belgium, but the final two races of the 12ft dinghy event in sailing were held in The Netherlands).

The Olympic Games were awarded to Beijing after an exhaustive ballot of the International Olympic Committee (IOC) on July 13, 2001. The official logo of the Games, titled "Dancing Beijing," features a stylised calligraphic character jīng (京, meaning capital), referring to the host city. Several new NOCs have also been recognised by the IOC.

The Chinese government promoted the Games and invested heavily in new facilities and transportation systems. A total of 37 venues were used to host the events including 12 newly constructed venues. At the closing ceremony IOC president Jacques Rogge declared the event a "truly exceptional Games" after earlier asserting that the IOC had "absolutely no regrets" in choosing Beijing to host the 2008 Games. The choice of China as a host country was the subject of criticism by some politicians and NGOs concerned about China's human rights record. China and others, meanwhile, warned against politicizing the Olympics.

The Games saw 43 new world records and 132 new Olympic records set. A record 87 countries won a medal during the Games. Chinese athletes won 51 gold medals altogether, the second largest haul by a national team in a modern, non-boycotted Summer Games. Michael Phelps broke the record for most golds in one Olympics and for most career gold medals for an Olympian. Usain Bolt secured the traditional title "World's Fastest Man" by setting new world records in the 100m and 200m dashes.

Wigan Athletic Football Club

Wigan Athletic Football Club is a professional football team based in Wigan, Greater Manchester, England. They compete in the Premier League, the highest division of football in England, in which they have been playing since their promotion from the Football League in 2005. Wigan's current spell in the Premier League is the only top flight run in the club's history. They play at the JJB Stadium, which they share with the rugby league club Wigan Warriors. The club is the youngest in its division, being only 76 years old..

FOOTBALLERS TAKE NEXT STEPS

The first cohort of former professional footballers has taken the next steps along their potential route from Pitch2Podium. The programme, backed by the football authorities and run by the English Institute of Sport (EIS) and UK Sport, aims to re-assign released young footballers into alternative Olympic sports. At the initial Olympic Talent Assessments in July, twenty-three players were short-listed for six targeted sports. September saw those identified for Flat-water Canoe and Skeleton gain first hand experience into the prospective Olympic journey that lays ahead.

Three athletes got the opportunity to attend a special Canoe Talent Assessment day at the National Water Sports Centre at Holme Pierre Point, Nottingham. Here, they were taken through a specific battery of tests designed to assess the myriad of characteristics required for World Class performance. Assessment included specific physiological tests looking to identify whether their capabilities could match those of current Olympians, following which the boys took to the water as coaches viewed their ability to learn the skills required. Their performances over the day made an immediate impression on GB Canoe Coach Alex Nikonorov.

“It’s great to see such talented athletes” he said. “Their general physicality is very impressive, as is their potential to learn canoeing skills quickly. As an Olympic coach this is very exciting and leads me to believe they have every chance of making rapid progress towards London 2012 given the right environment.”

Those impressing on and off the water have been invited to partake in a longer, more intensive, Talent Confirmation programme. This will be under the watchful eye of Olympic coaches and sports scientists who will meticulously track their progression in the sport.

Later that month, nine athletes made the journey to Bath to attend a special two day British Skeleton Talent camp. After surpassing the required Phase one targets set by the sport, further assessments were undertaken. Coaches worked very closely with the athletes to measure their Skeleton potential, with a particular focus being on their push-start.

From this, four athletes have been selected to attend a special skeleton familiarisation camp in Cesana, the site of the Torino 2006 Winter Olympics. The camp will involve a more extensive investigation into their ability to learn new skills as well as their responsiveness to working on ice.

Skeleton Talent Coach Greg Kirk has been pleased with the progress so far. “We saw boys at Phase two go way beyond their comfort zone, excelling in activities that are not ‘normal’ for them” he said.

Little Master Breaks Lara's Record

Hurdles

Hurdling is a type of track and field race. There are sprint hurdle races and long hurdle races. The standard sprint hurdle race is 110 metres for men and 100 metres for women. The standard long hurdle race is 400 metres for both men and women. Each of these races is run over ten hurdles and they are all Olympic events.

Other distances are sometimes run, particularly indoors. The sprint hurdle race indoors is usually 60 metres for both men and women, although races 55 meters or 50 metres long are sometimes run. A 60 metre indoor race is run over 5 hurdles. A shorter race may have only 4 hurdles. The long hurdle race is sometimes shortened to 300 metres or 200 metres, usually for indoor or high school races.

There are two basic hurdle heights: high hurdles and intermediate hurdles. The sprint hurdle races (60 m, 100 m and 110 m) use high hurdles, which are 42 inches (1.07 m) high (39 inches, or 0.99 m, in U.S. high school competition) for men and 33 inches (.84 m) high for women. Long hurdle races (400 m) use intermediate hurdles, which are 36 inches (.914 m) high for men and 30 inches (.762 m) high for women. Slightly lower heights (generally 3 inches (76 mm) lower) are sometimes used in youth or high school events.

Indoor athletics

There are two seasons for track and field. There is an indoor season, run during the winter and an outdoor season, run during the spring. Most indoor tracks are 200 metres and consist of four to six lanes. There are also some 150 metre indoor tracks, and others as small as 120 metres have been used. Some "oversize tracks" (larger than 200 metres) are popular for American collegiate athletics despite the fact that they are not considered valid for setting indoor records. Often an indoor track will have banked turns to compensate for the tight radius of the turns.

In an indoor track meet athletes contest the same track events as at an outdoor meet, with the exception of the 100 m and 110 m/100 m hurdles (replaced by the 55 or 60 m sprint and 55 or 60 m hurdles at most levels, or the 55 m sprint and hurdles at the high school level), the 10,000 m run, 3,000 m steeplechase, 400 m hurdles. Indoor meets also have the addition of a 3,000 m run normally at both the collegiate and elite level, instead of the 10,000 m. The 5,000 m is the longest event commonly run indoors, although there are situations where longer distances have been raced. In the mid 20th century, there was a series of "duel" races on Madison Square Garden's indoor track, some of which featured two men racing a marathon (42.2 km). However, this is an extremely rare occurrence, for obvious reasons. In some occasions, there may also be a 500 m race instead of the open 400 m normally found outdoors, and in many college championship races indoors both are contested.

In field events, indoor meets only feature the high jump, pole vault, long jump, triple jump, and shot put (weight throw). Due to space limitations, these events take place on the infield, within the circumferential track. The longer throws of javelin, hammer and discus are added only for outdoor meets, as there is normally not enough space in an indoor stadium to house these events.

Other events unique to indoor meets (especially in North America) are the 300 m, 600m, 1000 m, and 35 lb (16 kg) weight throw. In some countries, notably Norway, standing long jump and standing high jump are also contested, even in the National Championships.

For multi-event athletes there is the Pentathlon for women (consisting of 60 m hurdles, high jump, shot put, long jump and 800 m) and heptathlon for men (consisting of 60 m, long jump, shot put, high jump, 60 m hurdles, pole vault and 1000 m) indoors.

Gym

The gym has a range of equipment including a treadmill, resistance equipment and free weights. It is fully accessible to people with disabilities and includes a weightlifting platform to allow the use of free weights under appropriate supervision. New users of the gym must complete an induction before using the gym equipment.

The young athletes aged eight years and above will be introduced to athletics and taken through a combination of coached activities that can lead on to participation at competition events.

Ideal for children who want to get their first taste of athletics. The emphasis is on fun and enjoyment, learning about how the body works and the skills associated with all the different athletics events.

To further skills learnt at junior level, senior sessions give young athletes the chance to develop skills associated with different running, jumping and throwing events with the opportunity to train and compete in upcoming events.

Supervised sessions offer a mix of gym and track based activities, plus a daytime session which is ideal for older adults.

Optical theory

The Muslim scientist, Ibn al-Haytham (965-1040), known as Alhacen or Alhazen in the West, in his Book of Optics (1021), developed a broad theory that explained vision, using geometry and anatomy, which stated that each point on an illuminated area or object radiates light rays in every direction, but that only one ray from each point, which strikes the eye perpendicularly, can be seen. The other rays strike at different angles and are not seen. He described the pinhole camera and invented the camera obscura, which produces an inverted image, and used it as an example to support his argument.[3] This contradicted Ptolemy's theory of vision that objects are seen by rays of light emanating from the eyes. Alhacen held light rays to be streams of minute energy particles[4] that travelled at a finite speed.[5][6][7] He improved Ptolemy's theory of the refraction of light, and went on to discover the laws of refraction.

He also carried out the first experiments on the dispersion of light into its constituent colors. His major work Kitab al-Manazir (Book of Optics) was translated into Latin in the Middle Ages, as well his book dealing with the colors of sunset. He dealt at length with the theory of various physical phenomena like shadows, eclipses, the rainbow. He also attempted to explain binocular vision, and gave a correct explanation of the apparent increase in size of the sun and the moon when near the horizon, known as the moon illusion. Because of his extensive experimental research on optics, Ibn al-Haytham is considered the "father of modern optics".[8]

Ibn al-Haytham also correctly argued that we see objects because the sun's rays of light, which he believed to be streams of tiny energy particles[4] travelling in straight lines, are reflected from objects into our eyes.[5] He understood that light must travel at a large but finite velocity,[5][6][7] and that refraction is caused by the velocity being different in different substances.[5] He also studied spherical and parabolic mirrors, and understood how refraction by a lens will allow images to be focused and magnification to take place. He understood mathematically why a spherical mirror produces aberration.

Avicenna (980-1037) agreed that the speed of light is finite, as he "observed that if the perception of light is due to the emission of some sort of particles by a luminous source, the speed of light must be finite."[9] Abū Rayhān al-Bīrūnī (973-1048) also agreed that light has a finite speed, and he was the first to discover that the speed of light is much faster than the speed of sound.[10] In the late 13th and early 14th centuries, Qutb al-Din al-Shirazi (1236-1311) and his student Kamāl al-Dīn al-Fārisī (1260-1320) continued the work of Ibn al-Haytham, and they were the first to give the correct explanations for the rainbow phenomenon.[10]
