Basketball shoe introduction
Basketball shoes, but also sneaker lovers into the term SNEAKER, so that SNEAKER has a broader definition. Basketball is a strenuous exercise. In order to cope with intense exercise, a pair of basketball shoes need to have good durability, support, stability, comfort, and good shock absorption.
The constant starting, emergency stop, jumping, and rapid left-to-right movement in basketball make you have to put the characteristics of the shoes in the absolute first when choosing basketball shoes. In addition, your personal playing style is also a very important factor, you can choose different types of basketball shoes you need based on this. At the same time, because you consume according to your own economic situation, it is practical, so don’t chase the wind blindly.
What is the role of basketball shoes?
1. Shock absorber function
Cushioning can be divided into two types: structural and material. Structural properties such as honeycomb structure and arch structure (Arch). Material properties such as air cushion (Air), shock-absorbing glue (Gel). The shock-absorbing ability of sports shoes is defined by ASTM as: “the ability to reduce the peak impact force by the increase in the time of external force.” Whether it is a material test or a human test, it is the impact force of the ground reaction force in the vertical direction. Impact force peak or peak acceleration is used as an evaluation indicator. If the peak impact force or peak acceleration is small, the sports shoe has better shock-absorbing function and can reduce the occurrence of lower limb injuries.
2. Anti-slip effect
The anti-slip effect of basketball soles is also friction. Most of the domestic basketball courts are concrete, wood, and PU. The research results show that wood board has the highest shock-absorbing ability, and concrete has the highest rebound ability. In terms of friction, PU material has the largest front friction force, and concrete has the largest rear friction force. The front friction force is the friction force of the shoe pulling forward; it is the force applied to the floor to help the human body make an emergency stop action. Rear friction is the propulsion force that helps the human body forward on the surface of the field.
The thickness and depth of the shading are the keys to influence. Utilizing the deformation of the sole texture can increase the friction between the sole and the contact surface, and relatively effectively improve the anti-slip effect of the sole. The large-area herringbone pattern is still a symbol of the strongest grip of sneakers so far.
3, energy rebound
It’s called elasticity. There are two main types of functional tests for sports shoes. (1) Material test: Place the sports shoes on the force plate or the ground, and perform various tests on the shoes themselves; (2) Subject test: The subjects wore sports shoes and tested them with various exercise methods (walking, running, and vertical jumping). According to the results of the vertical jump test of the human body, there is no difference in jumping height between bare feet and wearing sports shoes, which shows that sports shoes have no substantial help for the elasticity required for jumping. The reason may be that the vertical jump of the human body is an active rebound, and if the rebound timing of the sports shoe sole cannot match the kicking action of the human body when the jump is taken off, it will lose its effect.
