summary

Now there are more and more people suffering from cold legs after practicing swallow style, Some people will be surprised or indifferent. I have an uncle who was a builder two years ago. In order to support his son to go to university and work all night, he only sleeps for a few hours a day. After a period of time, he always finds that his lower limbs are very cold. At first, he didn't pay much attention to it, so it's just better to cover his legs with cold quilts, but he didn't expect to get any better. Now he still finds that his lower limbs will hurt Pain, later told his son, his son quickly took him to see a doctor, the doctor said uncle diagnosed with fatigue necrosis of the femoral head, at this time he was surprised, the original is not simply afraid of cold. Later, the doctor told us some principles, and I'll share them with you.

What's the matter with the leg cold after practicing the swallow style

First: straight leg: when doing this action, you will unconsciously straighten the thigh completely for a long time, resulting in the thigh thickening. For example: standing alone ~ most people stand upright on the surface, but we should avoid the leg thickening, and consciously lengthen the leg. (reason ~ take the quadriceps femoris of the thigh as an example, when lengthening the leg, the muscle is lifted up; if it is not very straight, After a long time, the lower end of the muscle will become a larger jar shape. That is to say, the muscle does not fully contract

Second: weight bearing by bending legs: the common forms of this movement are weight lifting, running (especially Sprint), cycling. These sports only lose the liver sugar and heat energy, which can not reduce the excess fat, but also make the thighs thicker and thicker

Third: static work: this kind of overwork will make the thigh thick. The concept of static work is that when the muscle contracts to a certain extent, the contraction amplitude is fixed, so that the action does not change. During this period, the nature of muscle work is called static work. For example: control movement in dance training

matters needing attention

It's easy to store fat here. The reason is that the muscles here are not easy to train and do not practice in place, so that the inner muscles are lack of ability, and the excess fat can not be consumed. The way to overcome is to make the thigh external rotation (which is often seen in ballet training) the maximum limit of external rotation, and strive to make the horizontal line of foot length parallel to the horizontal line of two shoulders; but pay attention to the front, back and inside of the thigh, For beginners, sit on the floor against the wall, stretch your legs forward, lift your feet and lift one leg 25 degrees.
