Description

Novel grip trainer

Technical Field

The invention relates to the field of fitness equipment, in particular to a novel grip trainer.

background

The grip strength reflects the strength of the muscles of the forearm and hand, and is one aspect of the muscle strength of the whole body. The strong grip indicates that the ability of the person to do fine work on the wrist is strong, and the grip also plays an important role in the whole body movement. Grip strength is affected by three factors: first, the flexor muscles produce strength during isotonic contraction, called dynamic grip strength, which is the determining factor for the magnitude of grip strength. The second is the force produced by isometric contraction of the flexor muscles, called the static muscle force. It can keep fingers in a certain posture by exerting force, and keep resultant force among small muscle groups. And the third is the correct holding posture, which coordinates the small muscle groups of the hand playing the role of antagonism, synergy and fixation in the holding action.

The existing grip strength training device takes the elastic force of a spring as resistance and achieves the effect of training grip strength by compressing the spring, but the grip strength training device takes the elastic force of the spring as training strength and cannot adjust the training strength. The spring can only be replaced if the strength is to be adjusted. Furthermore, after the spring is used for a long time, the elasticity is weakened, the damage is quick, and the grip strength training effect is influenced. The existing spring-grip dumpers mainly train by one hand, and only two spring-grip dumpers can train simultaneously when two hands train, which is inconvenient. Therefore, a novel grip trainer is provided.
