Technical Field

The invention relates to the technical field of training pads, in particular to a karate training pad with good anti-skid performance and a manufacturing process thereof.

Background

The karate is formed by combining traditional fighting with lucuma martial arts Tang hand in Japan, and originates from the Tang hand in Wudao and lucuma. The Tang hand is developed by introducing Wushu into the Wushu ball and combining with the local Wushu ball hand, and the Japanese native also combines the wrestling, throwing and other wrestling skills of Jiuzhou and Benzhou with the Tang hand to finally form the karate. After the second war, it was widely spread throughout the world by army publicity. The empty hand includes various techniques such as kicking, beating, throwing, holding, throwing, locking, twisting, reverse skill, acupoint pressing and the like, and weaponry is also exercised in some genres. The air hand way of the twelfth sub-operational society of Guangdong island in 1994 becomes a formal competition item for the first time, and the competition field of the air hand way is generally 8 multiplied by 8 meters; as for the game items, there are two kinds of race (type) and combat (team hand), and in the team hand game, one effective attack causes the opponent to lose the fighting ability instantaneously or the center of gravity is moved significantly as a score criterion.

Since 1991, a boxer's meeting is taken as a representative to formally enter the mainland of China; several genres have been developed to date including the open billows, the firm soft stream, the extreme guild and the fairway. The martial arts association airdrome committee officially established in shanghai in 2001, 4 months, marks that the airdrome in mainland china enters the formal phase.

When carrying out the karate training pad, generally all carry out on the training pad, comfort level when multiplicable training also can reduce the injury to the health when falling down on the ground in the training process. However, the toughness and the skid resistance of the existing empty-hand training mat are still poor, and further improvement is needed.
