Evolution of sports shoes

We're back in the middle of the Olympic Games fever. Our top athletes at the highest level of competition and strive for the highest marks in their field.

The majority of older people will remember shoes with rubber soles that have been traditionally worn in physical education in most schools in Europe. These were in any color you like as long as it was black or white available.

These were offset by air, gel-filled capsules were replaced by superior technicalPerformance. They come in a variety of colors, shapes and forms and are available for both their appearance that their performance.

Advanced manufacturing techniques that have enabled the development of vulcanisation plimsoll, which is still used today is called. This process uses heat, melt the rubber and fabric. Sulfur is used in the process.

Trainers were revolutionary at the time as they move to comfort, were lightweight and allows the userto silence. Sneakers became known as sneakers, and have been sold on a large scale in America in 1917.

In the four years since the last Olympics in Athens technology has moved a bit 'and has certainly moved on Plimsoll.

Trainers and clothing has become lighter and stronger. But what is the technical part, had to play in improving the performance of the Nike -trainers.com/index.php http:// [? Option = com_content & task = view & id = 21 & Itemid = 2]our Olympic athletes?

Sports shoes and trainers have developed, we have different shoes for each event and each pair of shoes made with a variety of materials selected for each number of their properties to set the strength and flexibility, and where. Materials such as Kevlar, which is ten times stronger than leather, leather or cloth that is thin, stable and blown low density polyurethane foam, a shoe extra cushioning and thermoplasticPolyurethane, which has a strong and flexible shoe.

As technology has developed, scientists have developed new composite materials that work together to produce a better performance than the two or three subjects.

Different materials have different properties such as stability, provides torsional rigidity and deformation. The weight is a material for a period of time it is applied creep (flatten and spread).

Some materials are for their useelastic properties, the ability to flex and bend when force is applied and then retain their original shape when the force is removed. Finally, some materials for their density, as the amount of matter can be explained in an object for the measurement of space, these materials are used usually chosen for cushioning.

Polyurethane is a unique material that features the elasticity of rubber with the hardness and durability of metal combined offer. The flexible nature of the polyurethaneto make upholstery, mattresses, earplugs, chemical-resistant coatings, specialty materials, adhesives and sealants, and packaging. It is also to rigid forms of building insulation, water heaters, refrigerated transport and commercial and residential cooling. There is a force used for the production of sports shoes for its light absorption as well as flexible, and the large torsion and bending. Kevlar is one of the most importantmanmade organic fibers ever developed. The fiber has a remarkable combination of properties that led to its use in a variety of commercial products since its invention in 1970. The Kevlar fibers are interconnected long molecular chains produced from poly - para-phenylene. Kevlar has a high tensile strength with low weight, structural rigidity, low electrical conductivity, chemical resistance, low thermal shrinkage, excellent dimensional stabilityStrength, high cut resistance, flame retardant and self extinguishing. Quite versatile indeed!

spiked running shoes are more than 100 years created by the British company Reebok in 1890. This puts the shoe was developed out of necessity. The founder of the company enjoyed and wanted a shoe to develop his speed should increase.

In 1925 a company named Adi Dassler, now known as Adidas created a line of shoes with hand-forged nails. They offered a number ofShoes for different distances. The company used the lighter and stronger materials to be made at the time of running shoes. Adi Dassler, the brother has found the Puma sports shoe company.

The integration of science and technology in the 1970s, manufacturers of sports footwear skilled employees to perform research, as human beings. They also studied the effect of shock on the body by the collision between the feet and the ground caused. Your search has contributed toSports Shoes develop new and improved.
Their research found three types of playing styles:

Neutral:

This is where the heel of the rotor contact with the ground and the foot in a straight line as it moves forward.

Pronation:

This is where the heel touches the ground, but this time the foot moves sideways as it moves forward. It refers to the active role of the foot.

Supenation:

This is where the heel hits the ground and rolls the foot outwards.

In modern materials such as foam, silicone, air or gel were added to the trainers, who used to damping to create in modern running shoes.

In 1970, a plastic called ethylene-vinyl acetate (EVA) was developed. This material is revolutionizing the construction of sports shoes. He was of small air bubbles that provide cushioning and absorb shock. This material is injected in the form as vectors, shaped heel.

Air Technology> Nike, which used to run a gas bag full of air in the sole of the shoe to cushion the impact, the first time in 1979. The pair of tennis shoes he was appointed head of the wind in these technologically advanced air-soles had provided a good basis for further development based Nike. Since then, athletic shoes have become more sophisticated and the prices of various sneakers have grown in line with advances in technology and value addedCharacteristics. Some shoes in 1980, sold also included a pump valve so you could inflate or lowering the heel of the shoe, a bicycle if they were.

After the introduction of Nike shoes [Nike -trainers.com/index.php http://], a technical advance occurred in 1972 when Bill Bowerman, while studying the pattern on a waffle iron, came up with a great idea - waffle soles . Bowerman then cooked some 'rubber into his waffle iron and glued to the floor a coupleShoes, which then gave the athletes to be tested. The athletes came with good reviews and the sneakers were well received in the market. The patented outsole revolutionized running for better traction in a lighter, more durable shoe.

In 2003, Americans spent an average of $ 50 (€ 28) a pair of sports shoes.
Companies sponsoring athletes at the top. This means that a fortune, the company's products have paid for a sports clothingCompetition.

The Olympics are the biggest sporting event in the world attracting worldwide television audience. This provides an ideal opportunity for sports companies to see their products. In addition to sophisticated athletes and athletes, athletes are now fantastic marketing tools for businesses of sports shoes.

Would not it be interesting if all athletes had to wear sneakers in the Olympics this year, the only choice we could do would be toColor, black or white?

We would then see the true Olympic champion.
