Description

Muscle stretching training device

Technical field

The present invention relates to the technical field of stretching training, specifically a muscle stretching training device.

Background technique

A muscle stretching training device is a piece of equipment used for muscle stretching training.

The muscle stretching training device is a convenient, adjustable and practical tool that can help users carry out effective muscle stretching training. The leg flexor is a kind of muscle stretching training device, which is used to stretch and train the thighs and thighs. Quadriceps and leg flexors usually consist of a frame, a seat cushion, a locking component, a working platform, a weight block, a tension rope, a weight adjuster and a handle. When using a leg flexor, the user first sits on the cushion and puts the Put your legs on the work platform, adjust the position, use the handle to apply force, bend and extend your calves upward, use the power of your calves to lift the work platform until you reach the appropriate degree of flexion and extension, keep it for a period of time, bend and extend your calves downward, and lift the work platform Put it down and return the work platform to the starting position. Repeat this action to stretch the quadriceps muscles of the thighs under the action of the tension rope and weight block. If you need to increase the weight of the training, you can adjust the weight adjuster to increase the amount. The weight of the weight block.

In real life, fitness personnel who have been exercising for a long time no longer need the guidance of a coach when training in the gym. When using a leg flexion and extension device in the gym, after the previous user uses the leg flexion and extension device, the next user A user may no longer actively adjust the angle of the seat, but directly adjust the weight and then sit on the cushion to exercise. Since the user needs to use the strength of the waist and legs to lift the calf to a certain distance, the user If the angle of the seat is not adjusted during leg stretching training, the angle of the hip joint is too large or too small. At this time, the rectus femoris muscle will not be fully exerted due to hip flexion to complete the knee extension movement, thus affecting the user's legs. The effect of partial stretching training. For this reason, we propose a muscle stretching training device.

The force endured by the legs increases first and then decreases, which can ensure The legs can handle the pulling force of weight blocks of different weights on the legs and lift the work platform to the highest point, which can reduce the impact on the legs caused by a sudden reduction in weight, thereby reducing damage to the legs. By using the buffer plate 5, the impact of the weight block on the calf can be reduced, thereby reducing fatigue during training and improving safety during leg stretching training.
