Description

A kind of core strength training device

technical field

The present invention relates to a kind of physical fitness training equipment, especially a kind of core strength training device which directly overcomes the resistance movement of the core muscle group or directly acts on the core muscle group to train the core muscle group so as to enhance the core strength.

Background technique

The concept of core strength originated from core stability, and the concept of core stability originated from spinal stability. In 1985, Panjabi first proposed the concept of spinal stability. He believed that spinal stability includes three systems: passive spine, active spinal muscles and neural control units; in 1992, inspired by spinal stability, core stability was proposed by him. . Kibler introduced the concept of core stability into competitive sports training for the first time. He believed that core stability has three functions: generating force, transmitting force and controlling force. Core stability is the result of core strength, and core strength is the concrete manifestation of core stability.

In recent years, core strength is a new thing in the field of competitive sports, which has attracted the attention of many scholars. At present, scholars at home and abroad have different understandings of the definition of core strength. Different people have different opinions, and wise people have different opinions. For example, Ian Hasegawa refers to the muscles on the abdomen, buttocks, lumbosacral region, chest and back as core muscles; Travis Brown refers to the muscles located in the abdomen and spine. The nearby large muscles are the core muscles, among which the rectus abdominus, external oblique, internal oblique, transverse abdominis and erector spinae are the most important core muscles; The 29 muscles including the external oblique, internal oblique, transversus abdominis, thoracolumbar fascia, quadratus lumborum, iliopsoas, gluteus maximus, gluteus medius and erector spinae are called core muscles. From the definition of this scholar, we know that the scope of the core muscle group is from the middle of the chest to the middle of the thigh, including the front, sides, and back, which can regulate the center of gravity of the human body to maintain the balance and stability of the trunk.

MARJORIE , JOHN D WILLSON , J EFFREY M WILLARDSON , KIM MSAMSON and other scholars determined the core muscle group in the lumbar spine-pelvis-hip joint area, and believed that the top of the core area is the diaphragm, and the bottom is the pelvic floor muscles and hip joint muscles. KATHL EEN R LUST scholars believe that the core muscles include the thorax and the entire spine, and regard the entire torso as the core area of the human body. the

Wang Weixing and other scholars expounded the scope of the core muscle group from the perspective of the relationship between the lumbar spine, pelvis and hip joint joints and the position of the center of gravity of the human body, and defined the core muscle group from the area below the human diaphragm to the area between the pelvic floor muscles. The muscle group between the diaphragm-pelvic floor muscle area is called the core muscle group, and the rectus femoris and biceps muscles on the upper thigh are also listed as the core muscle group. These muscle groups wrap the lumbar spine, hip joint and pelvis from three levels of the sagittal plane, frontal plane and horizontal plane of the human body. Li Wenxia and other scholars believe that the core part is composed of the waist and abdominal muscles, including the transverse abdominus, internal oblique, external oblique, rectus abdominis and erector spinae.

J·H Pilates explained the scope of the core muscle group from the perspective of the relationship between the overall muscle group and the local muscle group. He believed that the core refers to the part from the ribs to the pelvis of the human body. The muscles it includes include abdominal muscles, back muscles Muscle group, transverse diaphragm, pelvic floor, crossed pelvic and lower extremity muscle groups. It believes that the core is a whole formed by the waist, pelvis, and hip joints, which refers to the middle link of the human body. The erector spinae is a muscle in the lumbar-pelvic-hip joint that is important for the stability of the spine and pelvis. The erector spinae and abdominal muscles cooperate with each other to complete the preparation posture of the human body before the start of the technical action and the maintenance of the trunk movement during the movement. The pelvic muscles also participate in the work here. The pelvic girdle is very important for stabilizing the normal position of the pelvis, especially for lower extremity acceleration, deceleration and hip adduction and abduction activities.

In today's competitive sports field, core strength training has become a hot spot in physical fitness training. It is very effective for the comprehensive and balanced development of the strength of the core muscle group and the balance and stability of the body center. It is an effective means to improve athletic ability and prevent injuries. Whether it is a professional athlete or an amateur practitioner, the quality of core strength directly affects the level of exercise ability of the human body during sports, and effectively protects the body from injuries during sports. Ordinary people can maintain a good physical and mental condition in daily production and life if they have good core strength support. As the pivotal link in the human body's biological movement chain, the torso plays a vital role in the performance of technical movements and the transmission of force (momentum) in sports. The stronger the core muscle strength ability during exercise, the better it can maintain the balance and stability of the trunk during exercise. It is obvious from the above that the core muscle group that can enhance the core strength as a whole refers to the muscle group that surrounds the waist, abdomen, and trunk center from below the diaphragm to the pelvic floor, including the transverse abdominis (transverse abdominis) , lumber multifidi, internal obliques, external oblique, rectus abdominis, quadratus lumborum, erector spinae, Diaphragm (respiratorydiaphragm), and pelvic floor muscles (pelvic floor), the main function of the core muscles is to maintain the stability of the human trunk, provide sufficient support for the spine, disperse the burden on the spine, and then make the limbs stable and fast The function of activities, it can be seen that if the training of the core muscles is neglected, it will easily lead to insufficient exercise capacity of the whole body, so the training of the core muscles is an important means to enhance the core strength.

At present, due to the large number of core muscles, many of which are small muscle groups, a variety of exercise methods are required to develop these muscles in a comprehensive and balanced manner. Practitioners must actively change various angles and positions of the trunk and limbs, and maintain the balance of movements. Accuracy is the only way to train the muscles that need to be practiced. In terms of the vertical height of the torso, the positions of the muscle groups to be trained are different from front to back, left to right, and it is difficult to have equipment suitable for all-round muscle group positions and height training. It is difficult to persist in the training process continuously. At the same time, exercise As far as abdominal muscle groups are concerned, sit-ups are the most commonly used exercise method, because their movements are simple and not affected by the venue, but sit-ups will put a lot of pressure on the spine, which will easily cause spinal injuries. In addition, the posture of sit-ups is lying down, so that the head of the human body will be slightly lower than the torso. In this way, when performing sit-ups, it is easy to be affected by the constant changes of the head. The phenomenon of dizziness and nausea occurs due to high altitude, especially for hypertensive patients who are more prone to physical discomfort. Therefore, traditional sit-ups are no longer suitable as the main exercise method for exercising abdominal muscles.

Although, Chinese Patent No. is 201110146917.9, a core muscle group training device and its use method provide a core muscle group training device for isokinetic muscle strength training and vibration stimulation, which allows the user's head to be trained The abdominal muscles are kept at a position higher than the trunk to avoid discomfort to the body, but it is basically limited to training the abdominal muscles, and the abdominal muscles are only part of the core muscles, so even if they are used frequently It is difficult to enhance the core strength of the user as a whole.

At the same time, the Chinese patent number is 201120090136.8, and the patent name is a space-type core strength training machine. It discloses a device that fixes the hip-sacral part of the practitioner's torso and suspends the human body in the air. The practitioner adjusts the posture of the sagittal plane and the vertical plane, and develops continuously and selectively. The practitioner stabilizes the trunk; but because only the hip and sacrum of the human body are fixed and suspended, the muscles to be trained are still limited, so it is difficult to fully Realize the enhancement of core strength. At the same time, the device suspends the practitioner in the air and changes the posture of the human body in the air. There are large safety hazards, which limit the range of users, that is, the users are professional athletes. Otherwise, the general population will not accept the safety hazard factor. Quite high training equipment, the important thing is that this device only has training effect, is difficult to realize health care physiotherapy effect.
