Improving the quality of any kind will have a good impact on the development of nike shoes sale quality. In contrast, the poor quality of some of its cheap nike shoes surely hinder improve quality. Power quality : it is the body's ability to resist resistance in motion. Various sports have attached great importance to the training of strength, improve power quality and increase muscle growth is to regulate nerve function. The reason is: the power comes from the contraction of muscles, the muscles will inevitably lead to increased muscle strength stout. The neural regulation of muscle coordination so that should force concentrated contraction of muscles against highly relaxed.
Manifests itself in reaction speed. Single operation completion time, frequency and speed of movement of the whole operation is repeated. However, nike free reactions are dependent on the speed and the speed of muscle contraction and ( of course sprint speed also depends on the pace of the span ). The general reaction rate nerve stimulation to occur with time from the beginning of the action it takes to represent. Feel more keenly, the more excited the brain, the more skilled technology, the shorter the reaction time. Muscle contraction speed ray ban store is a solid degree of fear by the type of muscle fibers, muscle strength, muscle tissue and reflex excitability of the decision.
Endurance Quality : cheap nike shoes prolonged exercise is the ability of the human body. Endurance and breathing has a very close relationship. When the movement of the body volume can be inhaled oxygen is larger, the number of the lack of oxygen can tolerate more, the endurance is better. So the lungs and respiratory system, heart and circulatory system, the stronger the muscle tolerance, its endurance is better. Flexility : cheap nike shoes body range of motion and measure the degree of muscle relaxation. cheap nike shoes Depending on joint range of motion, joint tissue surrounding the size, as well as ligaments, tendons, muscles and skin stretching.
