Centrifugal contraction (discussed)

Recently, Hulu silk walking brother 2f8c1 brother in the post all talked about let the spasm muscle group do centrifugal contraction to solve the spasm problem, reduce muscle dystagon
method
Gray0110 brother in 2007-10-18's post questioned this, paralysed motion analysis and environmental correction of the topic is too much, has not come to talk about, I use centrifugal contractions in practice to enhance muscle strength, now open a new post discussion, welcome everyone to develop their views.
2f8c1 view
centrifugal contraction Centrifugal contraction easily activates the moving unit, increases its discharge rate, a smaller collection rate can produce greater muscle strength, while centrifugal contraction is accompanied by a pull on the viscous elastic
tissue
, which inhibits the reconstruction of the viscous elastic tissue and promotes functional recovery.
characteristic of centrifugal contraction High muscle dystronomy is the loss of centrifugal contraction function, and centrifugal contraction training for spastic muscles is one of the methods to prevent muscle dystofliation and reduce muscle dystofness. We currently believe that centrifuge contraction is more important than centrifuge contraction, strength according to the patient's performance to determine, tired on the next action, or make 10 to 20 times. It is important to train the disordered muscle group for centrifugal contraction, and any muscle group will not spasm as long as centrifugal contraction can be done at will. Fortification of centrifuge contraction and deficiency of centrifuge contraction.
spasms in certain conditions show the difficulty of centrifugal movement, if the muscles can complete centrifugal movement at will, there is certainly no spasms, but the patient's spontaneous movement, clinically commonly used joint activity training technology, muscle strength training technology are in the strengthening of convulsion, which is an important environmental factor of spasms. We oppose simple joint activity training, advocate joint activity training using gravity without strengthening dominant muscle groups, and emphasize the importance of centrifugal contraction.

Simply put, please point out: human survival needs to adapt to the environment, and for posture, the most need to adapt is the gravity of the earth, the lower limb extension muscle and upper limb flexion group in order to resist gravity, easy to constrict to the heart, these muscles are also the dominant muscle group. But functions require bidirectionality, such as lifting heavy objects and lighting them on the ground as a complete job of handling, where the centrifugal contraction and centrifugal contraction of the upper limb flexion group are required.
of PNF is a technique that specializes in training the centrifugal and centrifugal contraction of a group of muscle groups. Perhaps there are a lot of comrades against PNF, think PNF is not scientific, my personal point of view is never superstitious about any technology, to use as a principle, without the exact evidence before excluding any technology, after all, we are in the learning stage, PNF emphasizes verb and spiral, but the application is not needed, lies in the reasonable application of learners.
I department of a cerebral hemorrhage patient (about 20 days in hospital), suffering from side upper limb hand function recovery is better, but shoulder and elbow control is poor, because I recently in teaching, the competent doctor let me return to the department to guide patients, I am using PNF iso-zhang combination, two days later the patient elbow lying function significantly improved, the patient is also very happy. Of course,
statistics
a statistical point of view can not reflect a law, I hope to be able to do a large sample of research in the future.
gray0110 Another question:
When you hold a heavy object in your hand and gently lower it, the biceps do centrifugal work, and when the elbows flexe, the biceps are subjected to very large forces (greater than the force generated by the biceps during the maximum effort) when the centrifugal work is done passively?
The former is actively and controlled to do centrifugal work, at least subjectively in doing centrifugal work, the latter is completely passive uncontrolled, subjectively not to do centrifugal work, but has been working hard to do centrifugal work, then in both cases the neuro-muscle physiological process is exactly the same?
liu_alex gray's question
Ask the first question: When you do muscle strength training, do you require patients to have training in, for example, to control the contraction force at will when waiting for long contractions? Have patients been required to be trained to control subjective force levels at will, such as when constricting to the heart? Have patients been asked to control adversity at will during centrifuge contractions, for example?
if you used this method a lot in your usual training, did you realize that this exercise is actually a very demanding exercise control training?
, passive stretching and active centrifugal contraction control are of course different physiological processes of neuromuscular control. Passive eelation rarely has sensory feedback (especially ontogenal sensations), and active centrifugal contraction control is in fact a very demanding bio-feedback process. Needless to say, everyone knows which training is more effective.
