Description

A device for training core strength of martial arts

technical field

The invention relates to the technical field of training equipment, in particular to a training device for core strength of martial arts.

Background technique

The concept of core strength originated from core stability. Core stability strength refers to the strength of the body against displacement or rotation when the core fixed muscles or some muscles that are both fixed and prime movers contract. Core dynamic strength refers to the force of skeletal muscle contraction to produce displacement or rotation of the body. Core strength is not only the main driving force for the formation of the core stability of the human body, but also can actively exert force during exercise. Core strength training is usually carried out under unstable conditions, so that more muscle groups, especially the auxiliary muscles around the joints, can participate in the movement and improve the ability to stabilize the joints and control the center of gravity during the movement. The core muscle group ranges from the middle of the chest to the middle of the thigh, including the front, sides, and back of the muscles that can regulate the center of gravity to maintain the balance and stability of the trunk.

In today's martial arts training field, core strength training has become a hot spot in martial arts training. It is very effective in developing the strength of core muscles in a comprehensive and balanced manner and the balance and stability of the central body. It is an effective means to improve athletic ability and prevent injuries. The quality of core strength directly affects the exercise ability of the human body during training, and effectively protects the body from injury during training. At present, due to the large number of core muscles, many of which are small muscle groups, a variety of training methods are required to develop these muscles in a comprehensive and balanced manner. The practitioner must actively change various angles and positions of the trunk and limbs, and maintain the movement Accuracy in order to practice the muscles that need to be practiced.

As far as exercising the core muscles of the waist and abdomen, the knee-touching abdominal crunches are the most basic training methods, because it is simple, safe, and effective. Knee-touching abdominal crunches are different from sit-ups. Many people think that strengthening core strength training is to practice sit-ups and various abdominal crunches. In fact, many novices have such a misunderstanding. The above exercises usually put a lot of pressure on the lumbar spine, such as Although the sit-up is simple and not affected by the venue, it needs to lift the lumbar spine, which will put a lot of pressure on the spine, which will easily cause spinal injury. In addition, the sit-up posture is lying down. In this way, when doing sit-ups, it is easy to experience dizziness and nausea due to the constant change of height of the head, especially for patients with high blood pressure more prone to physical discomfort. Therefore, traditional sit-ups are no longer suitable as the main way to exercise the core strength of the abdominal muscles.

The waist and abdomen core is the center of the upper and lower limbs of the human body. The biggest advantage of strengthening the waist and abdomen core strength is that it can stabilize and protect the lumbar spine in daily life, and at the same time improve the overall sports performance, thus providing a stable central strength for martial arts training;

Exercise the waist and abdominal core can be achieved through the following movements:

1. In the above-mentioned action of touching the knees and abdomen, the knees are kept bent, and the lumbar spine is always attached to the ground even when the force is exerted. The pressure on the lumbar spine is very small, but when the thoracic spine is lifted off the ground, the abdominal muscles will have Obvious tension, exhale when you lift up with force, lift the thoracic spine off the ground, the stomach must be adducted, touch the knees with both hands, there will be obvious tension in the abdominal muscles, and this tension will become stronger and stronger. When the back returns to the ground, inhale, you can’t release the force immediately. In the centrifugal stage, you inhale and slow down. When you lift up, you can go faster, but when you return to the ground, you need to control the slow down, so that the abdominal muscles are stimulated in the centrifugal stage. to be effective;

Many people have neck pain when they practice abdominal crunches. Avoiding neck pain can make the chin retract as much as possible. The cervical vertebra is in a neutral position, so as to avoid the neck exerting force when you lift your body, so that the first force of getting up is the chest. When the chest is raised, the thoracic spine is facing Squeeze the abdominal muscles from the front and top, the neck is passive, and the chest is lifted up, so that the neck is always in a neutral and stable state, and the hands touch the knees;

2. Another action, touching the knee joint of the opposite leg with the elbow, can be particularly efficient, not only can train the rectus abdominis, but also strengthen and stimulate the oblique muscle, the thoracic spine is always lifted off the ground, in order to reduce the pressure on the lumbar spine, The two legs, especially the calf, cannot move very parallel back and forth, because the lumbar spine tends to arch upwards when this parallel front and rear movement is performed, and the pressure on the lumbar spine is still somewhat large;

3. The third action, the hip bridge, the position of the feet, the distance between the heels and the buttocks, keep the knees as wide as the shoulders, if the core of the waist and abdomen is the main, the toes are straight forward, if you want to stimulate the buttocks, The feet are separated, the toes are slightly outward, and the buttocks will be tightened when the peak is contracted;

When rising, the pelvis is rolled inward, and the lumbar spine is attached to the ground. When lifting up, the waist and hips form a whole, do not let the lumbar spine arch upwards, and the body, knees, hip joints and chest are in a straight line.

The above three movements are relatively basic and have good effects, but one of the contradictions is that it is difficult to ensure the standard of movements when there is no support, especially when a person is training, once the posture is wrong, it will not only affect the training effect, but also lead to twice the effort , it is also easy to be injured, and blindly increasing the strength of the support, the core strength can not be well trained;

In addition, if you want to increase the strength, you need to increase the weight, put the kettlebell or dumbbell on the upper abdomen, and increase the angle of hip flexion, because the strengthening training of all muscles must be extreme stretching and then extreme tightening, so The effect of muscle stimulation and training will be better; however, the existing core strength training devices have a single training method, incomplete core muscle training, or use a more extreme way of training but ignore major safety hazards. For this reason, we propose A core strength training device for martial arts solves the above problems.
