How does muscle stiffness do

summary

As a result of not exercising for a long time, my body is getting weaker and weaker, so I will do a lot of exercise these days. However, I feel that my muscles are tight and I have no strength these times. The doctor said that it is caused by muscle stiffness. Today, let me tell you what to do with muscle stiffness.

How does muscle stiffness do

First: the muscle bears the load for a long time and with high intensity, consumes more energy and has a large oxygen debt. Lactic acid will accumulate in the muscle, causing changes in the internal environment of the muscle, such as the decrease of blood sugar. At this time, the working ability of the muscle will decline, and it is easy to appear the phenomenon of muscle stiffness. Arrange the appropriate amount of exercise and exercise intensity and density: we should proceed from the reality, reasonably choose the intensity, density, timeliness and quantity, and arrange the amount of exercise and exercise intensity and density.

Second: people with poor strength or long-term interruption of exercise, suddenly carrying out heavy and high-intensity exercise, are easy to cause excessive muscle load and insufficient oxygen supply, and a large number of metabolites (lactic acid and carbon dioxide) accumulate in the muscle, which will make the muscle stiff and sometimes cause muscle cramps. Training should be varied: the muscle groups to be trained should be comprehensive, the means of practice should be diversified, and the muscles with and without exertion should work alternately.

Third: after muscle cramps, the range of contraction and extension will be reduced, and the action will be uncoordinated (if the action is not skillful or too hard, the muscle will be pulled, resulting in injury accidents). In this case, the cerebral cortex will appear protective, so that the muscle work ability is reduced, thus aggravating the muscle fatigue. If the stiff muscle can not relax and rest, its function will be lower and lower, and the degree of muscle stiffness will be greater and greater.

matters needing attention

After a long period of inactivity, we should pay attention to muscle relaxation, do enough preparatory activities, take more hot baths, massage more to relax muscles, avoid keeping a posture unchanged for a long time, and pay more attention to diet.
