Description
Technical Field
The invention relates to the technical field of lumbar and dorsal exercises, in particular to an isometric contraction exerciser for lumbar and dorsal muscles.
Background
The back muscle is the muscle crowd that is located the back rear of the waist, stretches the motion after for the backbone and provides original power, also is the position of keeping simultaneously, guarantees the prerequisite of backbone stability, and the back muscle includes psoas and dorsal muscle, and the lumbar vertebrae divides shallow layer and deep: the superficial layer comprises latissimus dorsi and inferior posterior serratus muscle, and the deep layer comprises sacrospinalis, transverse process spina muscle, intertransverse muscle and intertransverse muscle; the psoas includes the quadratus lumborum and the psoas major. For healthy people, due to lack of active and effective functional training on lumbar and back muscles in daily life, waist soreness and discomfort often occur due to fatigue of the lumbar and back muscles after long-term bad life or working habits such as bending over a desk, driving and the like, and chronic waist pain develops in the past, which greatly affects the quality of life. In addition, weakness of the back and waist can seriously affect the stability of the lumbar vertebrae, and the loss of stability of the lumbar vertebrae is an initial factor for the degeneration of the lumbar vertebrae and the development of degenerative changes of the lumbar vertebrae (prolapse of lumbar intervertebral disc, lumbar spinal stenosis and spondylolisthesis). For a patient after thoracolumbar surgery, long-term disuse and nerve loss muscular atrophy after surgery can be caused by the fact that the posterior lumbar back muscles and the posterior medial branches of spinal nerves distributed on the lumbar facet joint capsule are damaged due to the fact that the surgical site is exposed, and then intractable lumbosacral pain after the surgery is caused. Therefore, the training of the lumbar and dorsal muscles is very necessary for healthy people and patients after lumbar vertebra surgery.
At present, the lumbar and dorsal muscle exercise method mainly comprises resistance isometric contraction and mainly comprises two methods: the first (figure I) five-point support method, the two knees in the supine position are flexed, the pelvis is lifted by taking the heel, the two elbows and the head as fulcrums, the abdomen and the knee joints are lifted as much as possible, and then the knees and the abdomen are slowly put down and fall together into one action; the second is (figure two) "little swallowfei", on the hard bed or clean hard floor, take the prone position, face down, only chest abdomen support body, head, limbs are lifted up, last 3-5 seconds, then relax muscle, limbs and head return to the original position and rest for 3-5 seconds, repeat the above-mentioned actions.
Both methods are active training of the back muscles of the waist, and the exercise effect of the back muscles cannot be undoubted after long-term adherence, but the defects that both methods need a certain field and special time, and clinical follow-up observation shows that even postoperative patients cannot achieve satisfactory compliance for the function training, so that the long-term adherence is difficult, while for healthy people, the patients need to take out the exercise for a fixed time every day, and the exercise needs to be completed by matching four limbs, so that other activities cannot be performed simultaneously, and the back muscles are boring and tasteless, and are more difficult to adhere. Therefore, although effective, the mainstream exercise method has the fatal defects of difficult execution and difficult persistence.
