Modern sports shoes in scientific and technological innovation
Along with the social economy and the development of science and technology, the connotation of the expansion has shoes. Exercise will not only in the arena of the deduction of swing, but also of leisure life into the public amateur. wholesale nfl jerseys Modern science and technology in the role of sports equipment, the effect is more significant to sports, sports level more outstanding. Therefore, as the most basic of the sports equipment–shoes has really permeate every in sport. In the broadest sense of the sports shoes (including professional sports shoes and ordinary sports shoes) in some sports and economic developed countries in total consumption of footwear have accounted for a third. Modern sports shoes has not only meet the durable comfortable function, but from different sports in search for movement characteristics, best performance and optimum shock stability. Among them, shockproof system and shoes become the focus in many elements.
Shoe materials including the mechanical properties of the elastic, quality and strength. Especially the forepaws of sole some material and shockproof system the elasticity of the material to run, jump and other activities will produce very big effect. The feet to the phase, material impact load effect, will be compressed. When be born buffer phase, materials and impact and compressed again. The mechanical significance has two aspects: (1) for ground and human body because the sole between intermediates, and for our bodies, because the elasticity of the sole, to face the impact of the human body will be effective buffer. Can make the lower limb muscle group concession sex reduced, so as to facilitate the push to stage after muscle restraint sex. from the perspective of energy conversion, because the elastic and can store part of elastic energy, realize the energy of the second use, after the push to increase when after deng force.The quality of the shoe size also affect the sports ability, shoes is human body addendum, the quality of the shoes, the bigger the movement process in the consumption of energy accumulation is bigger also, in order to ensure sufficient ministry sport security protection, under the premise of reduced heavy shoes is very effective. Nike for meters female air Jones specially designed no heel running shoes should be card this.
Cellular mattress shockproof system is made of a number of small bee room is small balloon composition, each is independent of the gas chamber, the whole piece of air cushion is like a honeycomb, each of the gas chamber can withstand the motion foot different points pressure, to scatter to foot pressure and get buffer. DMX live air cushion the shock mounting system is sports shoes forepaws have a atmospheric room, except the sole of the foot even after fitted with a atmospheric outdoor, more added heels and side air cushion, can prevent foot turned on side. Which type of air regulator to buffer air circulation more stable, protect the foot arch muscle. In addition, in order to avoid a sprained his ankle, relieve heel reaction, avoid vertebrae, and the oppression on knee, shoe arc feet by the design, make the heel foot first touchdown, borrow it from TUP support piece will increase stability, through the living room of air cushion of air circulation, play shock absorption, compressive and comfortable function.
(3) the German sports goods patriarch-ADIDAS (ADIDAS)Torsion system is based on the company put forward in the 1980 s “correct running skewed” theory. Cheap NFL Jerseys According to this theory, the sole before the palm and heel be torsion groove space into two parts, disconnect part called torsion slot (or article torque) connection. Due to the existence of torsion trough, the foot may, according to the need of running posture, let nature take its course of produce and produce torque twist, and under the action of torque, effective control reverse Angle, the twist of control in a certain range. When running from the ground, because the article torsion feet swinging and winding, produce the leverage to force, control reverse Angle, can to a certain extent increase the energy of the running, and can twist the legs to compensate for the damage caused by. When the torsion created, if not enough to prevent torque caused by the sole ankle ankle shoes birth; In 1960 the upper and sole sulfide adhesion; In the 70 s, PUMA launched PU multi-function cleats and dismantle the slippery piece, make football shoes more flexible, durable, light; 80 s-can change the nail multi-function football shoes, it’s shock absorption EVA widely be the standard; In the 90 s, PUMA shoes to join KELVAR materials in surface, use a metal to prevent slippery piece, head of the shoes and easy loss spikes with friction coefficient
