Description

Technical Field

[0001] The invention relates to the technical field of training equipment, and in particular to a core strength training device for martial arts. Background Art

[0002] The concept of core strength originated from core stability. Core stability strength refers to the ability of the body to resist displacement or rotation when the core fixed muscles or certain muscles that are both fixed muscles and prime movers contract. Core dynamic strength refers to the force of skeletal muscle contraction to cause the body to displace or rotate. Core strength is not only the main driving force for the formation of human core stability, but also the ability to actively exert force during exercise. Core strength training is usually carried out under unstable conditions, so that more muscle groups, especially auxiliary muscles around joints, participate in exercise, and improve the ability to stabilize joints and control center of gravity during exercise. The core muscle group ranges from the middle of the chest to the middle of the thigh, including the front, sides, and back, which are a general term for muscles that can regulate the center of gravity of the human body to maintain trunk balance and stability.

[0003] In today's martial arts training, core strength training has become a hot topic in martial arts training. It is very effective in developing the strength of the core muscles and the balance and stability of the body's central nervous system in a comprehensive and balanced manner. It is an effective means to improve athletic ability and prevent injuries. The quality of core strength directly affects the level of athletic ability of the human body during training, and effectively protects the body from injuries during training. At present, since there are many core muscles, many of which are small muscle groups, a variety of training methods are needed to develop these muscles in a comprehensive and balanced manner. Practitioners must actively change various angles and the positions of the trunk and limbs, and maintain the accuracy of the movements in order to practice the muscles that need to be practiced.

[0004] As far as exercising the core muscles of the waist and abdomen is concerned, the knee-touching crunch is the most basic training method because it is simple, safe, and effective. The knee-touching crunch is different from sit-ups. Many people think that strengthening core strength training is to practice sit-ups and various crunches. In fact, many novices have such a misunderstanding. The above exercises usually put a lot of pressure on the lumbar spine. For example, although sit-ups are simple and not affected by the venue, sit-ups require lifting the lumbar spine, which will put a lot of pressure on the spine and easily cause spinal damage. In addition, the sit-ups are in a lying position, which makes the head of the human body slightly lower than the torso. In this way, when doing sit-ups, it is easy to feel dizzy and nauseous due to the constant change in height of the head, especially for patients with hypertension. Physical discomfort is more likely to occur. Therefore, traditional sit-ups are no longer suitable as the main exercise method for exercising the core strength of the abdominal muscles.

[0005] The waist and abdomen core is the center of the human body's upper and lower limbs. Strengthening the waist and abdomen core strength has the greatest benefit of stabilizing and protecting the lumbar spine in daily life, while improving overall sports performance, thus providing a stable central strength for martial arts training;

[0006] The following exercises can be used to strengthen the core of the waist and abdomen:

[0007] 1. For the knee-touching crunch mentioned above, keep your knees bent. Even during the force phase, keep your lumbar spine close to the ground. The pressure on your lumbar spine is very small. However, when the thoracic spine is lifted off the ground, your abdominal muscles will have a noticeable sense of tension. Exhale when exerting force to lift up. Lift your thoracic spine off the ground. Your stomach must be adducted. Use your hands to touch your knees. Your abdominal muscles will have a noticeable sense of tension. This tension becomes stronger and stronger. Inhale when your back returns to the ground. Do not release the force immediately. Inhale while slowing down during the eccentric phase. You can be faster when lifting up, but you must control yourself to slow down when returning to the ground. Only in this way can the stimulation of the abdominal muscles during the eccentric phase be effective.

[0008] Many people will have neck pain when doing sit-ups. To avoid neck pain, you can retract your chin as much as possible and keep your cervical spine in a neutral position. Avoid using force on your neck when you lift your body. The first force point for standing up is the chest. When the chest is lifted, the thoracic spine presses the abdominal muscles forward and upward. The neck is passive and is lifted up with the chest. This keeps the neck in a neutral and stable state. Touch your knees with your hands.

[0009] 2. Another movement is to touch the knee joint of the opposite leg with the elbow. This can be very efficient. It can not only train the rectus abdominis, but also strengthen and stimulate the oblique abdominal muscles. The thoracic spine is always lifted off the ground. In order to reduce the pressure on the lumbar spine, the two legs, especially the calves, cannot move very parallel forward and backward, because this kind of parallel forward and backward movement makes the lumbar spine tend to arch upward, which still puts a lot of pressure on the lumbar spine.

[0010] 3. The third exercise is the hip bridge. The position of the feet is one palm away from the buttocks. The knees are kept shoulder-width apart. If the waist and abdomen are the main focus, the toes are pointed straight forward. If the buttocks are the main focus, the feet are separated and the toes are slightly outward. The buttocks will be tightened when the peak contraction occurs.

[0011] When you lift your body, roll your pelvis inward and keep your lumbar spine close to the ground. When you lift your body, your waist and hips should form a whole. Do not let your lumbar spine arch upward. Your body, knees, hip joints and chest should form a straight line.

[0012] The above three movements are relatively basic and have good effects, but there is a contradiction in them. It is difficult to ensure the standardization of the movements without support, especially when training alone. Once the posture is wrong, it will not only affect the training effect, resulting in half the result with twice the effort, but also easy to get injured. If you blindly increase the strength of support, the core strength will not be well trained.

[0013] In addition, if you want to increase the intensity, 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 extremely stretched and then extremely tightened, so that the muscle stimulation and training effects will be better; however, the existing core strength training devices have a single training method, the core muscle training is not comprehensive, or a more extreme method is used for training but greater safety hazards are ignored. For this reason, we propose a core strength training device for martial arts to solve the above problems. Summary of the invention

[0043] The technical solution provided by the embodiment of the present invention has the following beneficial effects:

[0044] For the training of core strength of martial arts, the present invention provides the possibility of multiple exercise modes, and the longitudinal slider and the longitudinal slide groove slide and match, and the waist fixed position can be adjusted according to the body proportions of different trainees, and the inclination angle of the calf support plate can be adjusted when the calf is lowered or raised according to the action requirements, and the bolts on the top of the connecting plate and the transverse connecting block can be rotated to adjust the inclination angle of the arc plate of the thigh support plate, which is highly practical; the present solution can provide support to ensure the standardization of the action, the training effect, and the safety during training;

[0045] (1) When doing knee-touching crunch training, the assistant trainee focuses his mind on the chest. The force point for standing up is on the chest. When the chest is lifted, the thoracic spine presses the abdominal muscles forward and upward. When the chest is lifted, the thoracic spine support plate is lifted upward, and the back of the neck can always be close to the U-shaped plate. When the thoracic spine is lifted off the ground, the weight ball slides on the slide bar toward the second support rod, thereby driving the weight plate forward to give the abdominal muscles a sense of pressure. When returning to the ground, the limit ring pulls the weight ball to slide toward the first support rod through the traction rope, which reduces the sense of pressure on the abdominal muscles. The length of the first support rod is greater than that of the second support rod, which can not only ensure a controlled slow descent, but also prevent the weight ball from returning to the first support rod when the height is too low and pressing on the chest position of the human body. It can not only ensure the safety of the trainee, but also play an auxiliary role in ensuring the standardization of the trainee's movements, and also ensure the effect of exercising the core strength of the waist and abdomen. The thoracic spine support plate provides a support for the head and neck of the human body, avoiding the neck from exerting force when lifting the body, and reminding the trainee to return to the position quickly even if it deviates slightly;

[0046] (2) For the action of touching the knee joint of the opposite leg with the elbow, the other preparations are the same as above, except that the vertical slider is slid to the upper middle position of the vertical slide groove, and the vertical slider is fixedly connected to the vertical slide groove by bolts, so that when the leg kicks forward, it can be tilted upward at a certain angle, so that the lumbar spine can better fit the ground, greatly reducing the pressure on the lumbar spine;

[0047] (3) For the hip bridge exercise, the preparation work can be referred to the preparation for the knee-touch crunch exercise. The difference is that the electric push rod drives the arc-shaped clamping plate to move toward the connecting seat and then remains stationary to prevent it from hindering the upward arch of the lumbar spine.

[0048] Another advantage of this solution is that it provides support and reminders for the trainee instead of simply increasing the strength. For example, a U-shaped board is used for support of the back of the neck instead of a semi-circular board, and there is a certain amount of space for the neck and other parts to move, so as to avoid discomfort to the trainee and provide greater comfort.

[0086] For the training of martial arts core strength, the present invention provides multiple possibilities of exercise modes:

[0087] When doing knee-touching crunch training, in the initial state, the thoracic vertebra support plate 201 is located in the rectangular groove 101, and the electric push rod 305 drives the arc-shaped card plate 303 to move toward the connecting seat 304. Since the side wall of the groove is set as a telescopic plate, the top of the telescopic plate is provided with a threaded hole, and the telescopic plate can be adjusted according to the height of the knees when the trainee lies down with his legs bent. The connecting plate 7 and the bolts on the top of the transverse connecting block 402 can be rotated to adjust the inclination angle of the arc plate 6 of the thigh support plate 403. Since the end of the calf support plate 404 away from the connecting rod 8 is provided with a telescopic rod 9, the end of the telescopic rod 9 is rotatably connected to the vertical slider 10, and the vertical slider 10 is slidably matched with the vertical slide groove 12, and then the vertical slider 10 can be slid to the bottom position of the vertical slide groove 12, and the vertical slide groove 12 can be fixed by the bolt. The slider 10 is fixedly connected to the vertical slide groove 12. After preparation, the trainee can lie on the bottom plate 1, with the back pressed on the thoracic vertebra support plate 201, the two arms are placed in the limiting ring 202 near the armpits, the back of the neck is against the inner side of the U-shaped plate 203, the waist is located between the two arc-shaped clamping plates 303, the thighs are placed on the arc-shaped plate 6 of the thigh support plate 403, and the calves are placed on the arc-shaped plate 6 of the calf support plate 404. The electric push rod 1 305 drives the arc-shaped clamping plate 303 to move toward the trainee's waist until it just clamps the waist, and then the training can begin. The trainee focuses his mind on the chest, and the force point for getting up is on the chest. When the chest is lifted, the thoracic vertebra squeezes the abdominal muscles forward and upward, and when the chest is lifted, the thoracic vertebra support plate 201 is lifted upward, and the back of the neck of the person can always be close to the U-shaped plate 203;

The waist is located between the two arc-shaped clamping plates 303, the thigh is placed on the arc-shaped plate 6 of the thigh support plate 403, and the calf is placed on the arc-shaped plate 6 of the calf support plate 404. The electric push rod 1 305 drives the arc-shaped clamping plate 303 to move toward the waist of the trainee until it just clamps the waist, and then the training can begin. Since the vertical slider 10 is fixed at the middle upper position of the vertical slide groove 12, when the leg kicks forward, it can be tilted upward at a certain angle, so that the lumbar spine can better fit the ground;

[0089] For the hip bridge movement, the preparation work can refer to the preparation for the knee-touch crunch training. The difference is that the electric push rod 305 drives the arc-shaped clamping plate 303 to move toward the connecting seat 304, and then keeps it still to prevent the lumbar spine from being hindered from arching upward.

[0096] The length of the first support rod 18 is greater than that of the second support rod 19, so as to prevent the weight ball 15 from being too low when returning to the first support rod 18 and pressing against the chest of the human body.

[0097] During training, the waist and abdomen are located below the weight plate 17. When the thoracic spine is lifted off the ground, the weight ball 15 slides on the slide bar 14 toward the second support rod 19, thereby driving the weight plate 17 forward to give the abdominal muscles a sense of pressure. When returning to the ground, the limit ring 202 pulls the weight ball 15 to slide toward the first support rod 18 through the traction rope 20, and the pressure on the abdominal muscles is reduced. The length of the first support rod 18 is greater than that of the second support rod 19, which can not only ensure a controlled slow descent, but also prevent the weight ball 15 from being too low when it returns to the first support rod 18 and pressing on the chest position of the human body.

[0098] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
