Description

A kind of force at the core trainer

Technical field

The present invention relates to a kind of physical fitness training device, espespecially a kind ofly by core muscle group, directly overcome resistance exercise or active force directly acts on core muscle group, thereby reach a kind of force at the core trainer that training core muscle group strengthens force at the core.

Background technology

The concept of force at the core comes from core stability the earliest, and the proposition of core stability comes from spinal stability.Panjabi in 1985 propose the concept of spinal stability first, and he thinks that spinal stability comprises passive vertebrae, active backbone muscle and three systems of neural control module; 1992, under spinal stabilization sexual enlightenment, core stability was thereupon by its proposition.First the concept of core stability is induced one competitive sport training of Kibler, it thinks that core stability has the strength of generation, transmits strength and controls strength three aspects: function.Core stability is the result of force at the core, and force at the core is the concrete manifestation form of core stability.

In recent years, force at the core is a fangle in athletics sports field, causes many scholars' concern.At present, Chinese scholars understands differently to force at the core definition, and the benevolent see benevolence and the wise see wisdom, and for example IanHasegawa is called core muscles with the muscle on belly, buttocks, lumbosacral region, chest and back; It is core muscles that Travis Brown be take near the big muscle being positioned at belly and backbone, and wherein rectus aabdominis, musculus obliquus externus abdominis, oblique, musculus trasversus abdomins and erector spinae etc. are topmost core muscles; Paul J G oodman is called core muscles with 29 muscle such as the rectus aabdominis in association, musculus obliquus externus abdominis, oblique, musculus trasversus abdomins, thoracolumbar fascia, musculus quadratus lumborum, iliopsoas, gluteus maximus, gluteus medius and erector spinaes.From this scholar's definition, learn, the scope of core muscle group is from the middle part of chest to large midleg, comprises front, both sides, can regulate and control gravity center of human body below and reach the general designation that maintains the stable muscle of trunk balance.

MARJORIE, JOHN D WILLSON, J EFFREY M WILLARDSON, the scholars such as KIM MSAMSON determine core muscle group at lumbar vertebrae-pelvis-hip joint position, think that the top at core position is diaphram, bottom is flesh and hip joint flesh at the bottom of pelvis.KATHL EEN R LUST scholar thinks that core muscle group comprises thorax and whole backbone, is considered as whole trunk the nucleus of human body.　

Wang Wei magnitude scholar is angle with the surrounding of lumbar vertebrae, pelvis and the hip joint associating of human body with the pass of position of centre of gravity, set forth the scope of core muscle group, core muscle group is defined in to human body diaphram with the region between flesh at the bottom of basin, muscle group between flesh region at the bottom of diaphram-basin is called to core muscle group, is positioned at rectus femoris on thigh, flesh biceps is also listed in core muscle group.These muscle groups wrap up lumbar vertebrae, hip joint and pelvises from three aspects of sagittal plane, frontal plane, horizontal plane of human body respectively.The scholars such as Li Wenxia think that core position is comprised of waist and abdominal muscles, comprise musculus trasversus abdomins, oblique, musculus obliquus externus abdominis, rectus aabdominis and erector spinae etc.

J H Pilates is angle with the pass of whole muscle group and local muscle group, set forth the scope of core muscle group, think that core refers to that human body rib is with the position down to pelvis, the muscle group that it comprises has the muscle group of flesh at the bottom of abdominal muscles group, dorsal muscles group, tabula flesh, pelvis, staggered pelvis and lower limb.It thinks that core is an integral body of waist, pelvis, hip joint formation, refers to the intermediate link of human body.Erector spinae is a muscle among waist-pelvis-hip joint, significant to the stability of backbone and pelvis.The worked in coordination poise of human body before technical movements start and the body work in motion process of erector spinae and abdominal muscle maintains, and at this pelvis muscle group, also participates in work.Pelvic girdle is extremely important for the normal position of stablizing pelvis, particularly for receiving the project of abduction exercise in lower limb acceleration, deceleration and hip joint.

And in athletics sports of today field, force at the core training has become a focus of physical training, it to general equilibrium to develop strength and the health maincenter balance and stability of core muscle group very effective, be the effective means that improves locomitivity and pre-antisitic defect.No matter be professional athlete, or amateurish practitioner, the quality of force at the core directly affects human body and is engaged in locomitivity height in motion process, and effectively protects health at the volley away from damage.If general people has good force at the core to support, also can in daily production and life, keep good mental and physical.Trunk, as the hinge link on human-body biological kinematic chain, plays vital effect to the transmission of the performance of technical movements and power (moving) amount at the volley.Core muscles strength ability is stronger at the volley, more can keep the stability of equilibrium of human body trunk in motion process.From upper, obviously learn, can overall enhanced the core muscle group of force at the core refer to from below diaphragm at the bottom of pelvis and around waist, belly, and the muscle group of trunk central authorities, comprise musculus trasversus abdomins (transverse abdominis), multifidus (lumber multifidi), oblique (internal obliques), musculus obliquus externus abdominis (external oblique), rectus aabdominis (rectusabdominis), musculus quadratus lumborum (quadratus lumborum), erector spinae (erector spinae), diaphragm (respiratorydiaphragm), and flesh (pelvic floor) at the bottom of pelvis, the major function of core muscle group is maintain trunk position stable, provide vertebra enough support forces, the burden of disperseing backbone to bear, and then allow four limbs stablize and the function of performance Fast Activities, hence one can see that, if ignore the training of core muscle group, be easy to cause the locomitivity of general not enough, therefore be the important means that strengthens force at the core to the training of core muscle group.

At present, because core muscles is more, having many is small muscle groups, these muscle of development of overall balance need to have diversified exercising method, practitioner will initiatively convert the position of various angles and trunk, four limbs, and keeps accuracy of action could practise the muscle that needs are practised.Vertical height from trunk, need the height at the muscle group place of training to differ all around, be difficult to the equipment that is applicable to omnibearing muscle group position and highly trains, training process is difficult to adhere to continuously, simultaneously, with regard to the muscle group of exercise belly, sit-ups are the motion modes that the most often used, because its action simply and is not subject to the impact in place, but the action of sit-ups can bring vertebra very large pressure, and then easily cause the damage of vertebra, the posture of adding sit-ups is lying posture, make the head of human body can be in the position a little less than trunk, thus, when when carrying out sit-ups, be easy to constantly change because of head the phenomenon that highly occurs dizziness and nausea, especially for hyperpietic, more easily there is uncomfortable situation.Therefore, traditional sit-ups have been not suitable as the main movement mode of exercising abdominal muscles.

Although, China Patent No. is 201110146917.9, a kind of core muscle group trainer and using method thereof provide the core muscle group trainer of a kind of uniform velocity exercise for power and vibrations stimulation formula, this device can allow user's head remain on the position higher than trunk in the process of training abdominal muscle, to avoid allowing health occur uncomfortable phenomenon, but its for be substantially defined in training abdominal muscle, and abdominal muscle is only as the part of core muscle group, therefore even if often use is also difficult to overall enhanced user's force at the core.

Simultaneously, China Patent No. is 201120090136.8, patent name is space formula force at the core exerciser, disclose a kind of hip sacrum position of the practitioner's of fixing trunk and human body has been hanged to skyborne device, although this device carries out the attitude of sagittal plane, vertical plane to hanging skyborne practitioner by motor, adjust, continuously, selectively develop practitioner and stablize trunk; But owing to only fixing and having suspended in midair the hip sacrum portion of human body, the muscle group of being trained or limited, so be difficult to whole realization, strengthen force at the core, this device is suspended on practitioner in the air simultaneously, conversion human body aerial statue, there is larger potential safety hazard, define user's scope, user is professional sportsman, otherwise general population is difficult to accept the training device that potential safety hazard coefficient is quite high, importantly this device only has training effect, is difficult to realize health-care physical therapy effect.
