In the United States and Britain are expressing distances in miles, but from 1976 to official records, only recognized metric distances (except for the mile race). In Europe and the Olympics, the distances are always expressed in meters.

100 meters, Sydney 2000The Athletics is the Olympic sport of excellence and the expectation is that more in the Olympics, their tests are performed in the Olympic Stadium and some away from it. Formerly tests Athletics were held in the early rounds of the games but now vie in the last 8 days, matching the end of the marathon ceremonyclosure.




The sport Olympic program consists of the following tests: speed, jumping, combined circuit and release, in total 24 tests are vying male and 20 female in the athletics there is currently no limit of participants as in other sports.

The meetings of outdoor athletics are usually held in a stage in which the central space is a clue, whose floor is ash, clay or synthetic material. The usual length of the runway is 400 m, has an oval shape, with two lines and two curves. Most of the shoots and jumps (called test field) occur in the zone inside the oval. There are disciplines special, as the decathlon (exclusively male), which consists of five tests track and field five, and heptalon (female only), which consists of four tests field and three runs.

Diving suits, Sports Diving





The diving suits are essential for dives in waters are warm and where the temperature is not the same as that of the body (32 ยบ C). They offer protection and thermal comfort allowing the diver to remain long enough in the depths.

*Types of diving suits

Existing materials are varied, since neoprene lycra until you can find lots of wetsuits.

With such a diver looking for does not go to extremes such as hypothermia, so it must choose the appropriate attire for water temperature and the activity performed.


*Wet suits

This type is called a wet suit, as between the skin and the inside of the suit creates a water film to come into direct contact with the body unable to afford their heat insulating the cold outside.

According to the temperature of water have different thicknesses, from 2 to 8 mm.It is essential that clothes will stick to the body to the water film is created to achieve warm.


* semi-dry suits

This type of suit was designed to immerse in cold water, so its minimum thickness is 7 mm.

The hood and boots are part of the suit, unlike the previous ones that usually come in separate parts.


* Dry suits

This type of dress means excellence in thermal protection and security. His material is designed to insulate the diver from the colder waters of the polluted well.

The main difference is that the wet to avoid cold water using air as an insulator. This can be a problem because it creates buoyancy, which makes it necessary to learn how to use previously.

Inflation has a mechanism that enters the air that insulates the body from the cold, and it requires the help of a partner to wear it.

The materials used in their manufacture are pressed neoprene and neoprene membrane.


Neoprene pressing

- Shock resistant
- Sticks to the body to perfection
- Excellent thermal insulation
- Limiting the mobility of the diver


Neoprene Diaphragm

- Allows more mobility by being lighter
- Less isolation
- Used with some clothes

Extreme bungee jumping








The origins of extreme bungee back to a rite that was practiced in Indian Vanuatu Islands, is still practiced and is the most extreme bungee all.

In this ancient Indian ritual jump from a wooden platform that has about 30 feet high, bound with ropes made of cane base.

Swimming








Swimming is the art of stand and move, using your arms and legs, on or under water. Activity can be as playful or as a competitive sport. Because humans do not swim instinctively, swimming is a skill that must be learned. Unlike other land animals given impetus in the water, in what is essentially a way of walking, humans have had to develop a series of strokes and body movements that propel him into the water with power and speed. In these movements and styles behind the evolution of competitive swimming as a sport.

Swimming can be practiced in any type of enclosure large enough water to allow free movement and it is not too cold, hot or turbulent. The currents and tides can be dangerous, but also pose a challenge to demonstrate the strength and value of the swimmers, as is apparent with the many successful attempts to cross the Channel.

Swimming was a sport highly esteemed in the ancient civilizations of Greece and Rome, especially as a training method for warriors. In Japan and competitions were held in the first century BC However, during the Middle Ages in Europe the practice was almost forgotten, as the water immersion was associated with continued disease epidemics of the time. By the nineteenth century and this bias disappeared, and in the twentieth, swimming has come to regard a valuable system of physical therapy and exercise is generally more beneficial than exists. No other exercise use many muscles of the body and so intensely. Moreover, increased influx of swimmers and the best techniques of construction and heating, have greatly increased the number of outdoor public swimming pools and decks around the world. The private pool, which was once a sign of exceptional privilege, it is increasingly common.





Techniques


The main obstacle to learning to swim is the fear of water or nervousness, which causes muscle tension. Much has been done on developing methods to reduce this psychological barrier. They often begin to teach very young children. While you can teach older people, the sooner learn to swim the individual, the easier it is. Teaching swimming is important to learn to coordinate the movements of hands and legs with breathing. Their learning has been incorporated into the curricula of schools in many parts of the world. During World War II teaching techniques were developed for large groups, teaching courses for troops as part of their training for combat.


There are five recognized swimming strokes, which have been refined since the late nineteenth century. These are: front crawl (also called freestyle because you can choose in freestyle competitions), the first version gave the English swimmer John Arthur Trudgen in the 1870s, back, who used it first U.S. swimmer Harry Hebner in the 1912 Olympics, breaststroke, the oldest style, known since the seventeenth century; butterfly, developed in the 1930s by Henry Myers and other American swimmers and recognition in 1950 as an independent style, and stroke in cost, basic style in the early years of competition, but now only used in non-competitive swimming.

1. Crol


In this style, one arm of the swimmer moves through the air with your palm down ready to enter the water, and elbow relaxed, while the other arm goes under the water. The legs move according to what in recent years has evolved as a kick oscillating reciprocating hips up and down with your legs relaxed, feet and toes inward to a point. For each complete cycle of the arms are held from two to eight kicks oscillating. This style is very important to breathe properly. You can take a full breath for each cycle of arms, inhaling through the mouth to turn his head to one side when you move the arm and then exhaling underwater when the arm moves back.


2. Fathom


In this style, the swimmer floats facedown, with arms pointing forward, palms around, and executes the following sequence of horizontal movements: open arms back to get in line with your shoulders, always above or below the water surface. They shrink the legs to bring them closer to the body, knees and toes out, and then stretched with a drive while the arms back to starting point at which starts the cycle again. The swimmer breathes underwater. The strokes must be lateral, not vertical. This is a very important point discussed in competitive swimming.


3. Butterfly


In the variant known as butterfly breaststroke, both arms together in front are carried over the water and then back at the same time. The arm movement is continuous and always accompanied by an undulating movement of her hips. The kick, called Dolphin, is a sharp downward movement and feet together.


4. Back


This style is similar to front crawl, but the swimmer floats back into the water. The sequence of movements is an alternative: one arm in the air with the palms outward flowing out from under the leg, while the other drives the body in the water. Also used here swinging kick.


5. Stroke side


It has many uses in non-competitive swimming. It is very useful as a salvage technique. Moreover, as it does not require much physical effort as other styles, suitable for long distances. It is also popular for recreational swimming because the head always stays above water. The swimmer floats on one of the two sides of his body and moves his arms alternately. The arm that is under water gives impetus to the head height, rises and returns to the waist, the arm is crossed over her waist and then gives impetus to his chest again. The legs are opened slowly and then contract sharply, giving a momentum kick, scissor, before stretching at all.




Competition


The swimming competition includes individual and team tests. In mixed races using the four styles of racing-crawl, back, breaststroke and butterfly in any order for individuals and another for teams. In tests of relay teams consist of four swimmers who take turns, with total time determines the winning team.


In international competitions the length of the tests between 50 and 1,500 meters. The world records are recognized only when set in pools of 50 m in length. Competition has become so strong that it has been necessary to define very precise rules for the various styles and to regulate the physical size and shape of the pool, equipment type, demarcation of the streets, water temperature, all important elements determining the performance. Electronic devices for measuring and timing have almost replaced the judges and timekeepers in the swimming events.


History


In modern competitive swimming was introduced in Britain in the late eighteenth century. The first such organization was the National Swimming Society, founded in London in 1837. In 1869 he created the Metropolitan Swimming Clubs Association, which later became the Amateur Swimming Association (ASA). The first national champion was Tom Morris, who won a mile race on the Thames in 1869. In the late nineteenth century, competitive swimming was being established in Australia and New Zealand and several European countries had already established their respective federations. In the U.S., the amateur clubs began to hold competitions in the 1870s.

The first Olympics of the modern era, held in Athens in 1896, also included swimming. In 1908 he organized the Federation Internationale de Natation Amateur for racing fans to celebrate. The women's competition was first included in the 1912 Olympics. International competitions have been sponsored by European amateur clubs to swimming since the late nineteenth century. However, until the 1920s, these competitions were not defined on a fixed regular basis. Britain had created some competition between member nations of the British Empire before 1910. The first official game of the British Empire, where the swimming was a major component, were held in Canada in 1930. Swimming now plays a key role in several other international competitions, the most prominent Pan American Games and Asian competitions, and Mediterranean.

The World Championship was first held in 1973 and is held every four years. The European Championship was first held in Budapest in 1926, there were five competitions between 1927 and 1947, from 1950 to 1974 he played with four-year intervals since 1981, take place every two years. There was a World Cup in 1979 when the U.S. won the competition in both male and female. The European Cup was first held in 1969 and since then has held every two years.

Swimming is a sport where competition is mainly focused on time. That's why in recent decades swimmers have focused on the sole purpose of breaking records. What once were surprising speed records of competitors from the likes of Duke Paoa Kahanamoku, Johnny Weissmuller, Buster Crabbe Clarence, Mark Spitz, David Wilkie, Shane Elizabeth Gould and Martin Lopez-Zubero, among others, have already been or will be overshadowed by new superlatives. Similarly, are continually breaking records set by distance and endurance marathon swimmers, such as the American swimmer Gertrude Caroline Ederle, the first woman to swim the Channel. Consequently, the gap between men and women in competitive swimming have been greatly reduced; has decreased the age at which swimmers can compete successfully and have not yet reached the physical limits of the specialty.


All about Spinning







Maybe you've heard about spinning and you have not yet quite clear what it is. However, in urban women tell you all about this discipline.

Spinning is a physical activity that develops on a stationary bike or static, without moving an inch of the place. However, spinning is hardly static: aerobic activity is very strong and not suitable for everyone.

A spinning class consists of a route "virtual" bike, which will be accompanied by special music that we will mark the different rhythms that we will continue pedaling.



In one class we will go through stages of intense, rapid cycling, as well as slow, rhythmic pedaling. It all depends on the music that will carry us, and the trainer's instructions.





According to experts, spinning not only promotes cardiovascular health, but also promotes concentration and self-improvement.


If you are interested in spinning, check on your gym if you can practice and if your physical conditions are optimal to do so. Spinning is not recommended for people with history of heart disease or joint problems because, at times, the pedal is too intense. Check with your doctor to see if spinning is suitable for you.
