Muscle fascia is the protagonist of pain!

Relevant explanations over the years include：

Lactic acid accumulation theory and free radical-induced inflammation theory

Or the theory of spasm or breakage of muscle fibers

Up to now

These statements are not enough to provide a full and complete explanation.

Lactic acid accumulation theory

It's been going on for years, but it's been overturned.

Because scientists have found that even if the concentration of lactate in the body is not high, there will still be post-exercise soreness. In addition, studies have confirmed that it takes only about 40 minutes for us to completely decompose the accumulated lactate in our bodies. However, muscle soreness usually occurs one or two days after intense exercise and lasts for several days.

Theory of Muscle Fiber Fracture

Sports science education of muscle fiber breakage theory is preferred.

This theory does not support massage for people with muscle soreness, because broken fibers indicate that the fibers are injured, and massage may worsen the broken condition. After the breakage of muscle fibers, local swelling and inflammation will occur one after another.

for a long time

Our explanation for this frequent phenomenon

Neither is the most rigorous nor correct.

And myofascial studies have found new answers.

Nordic anatomists did an experiment on this.：

They asked the subjects to step on the chair with one foot fixed, and then retreat with the bow and arrow of the other foot and repeat it many times. The second foot must brake frequently, which is more likely to cause soreness and fatigue. Then the sore tissue was observed by electron microscopy. The researchers found that local muscle fibers did change, and in the "sarcomere" region, the smallest unit of muscle cell composition.

The findings of the study：

Some muscle structural proteins changed. More precisely, the book mentions that "actin" and "myonectin" have changed after intense exercise. However, there are still other mysteries. The extramuscular myofascial tissue is the most serious victim.

Recent research findings：

After vigorous exercise, the protagonist who really feels pain is the "deep fascia", which is the "epimyea" covering the muscle.

The findings of this study originated from the 2007 seminar.

Robert Schleip sat with several experts on muscle pain

Discuss their upcoming post-exercise pain study

They used saline needles to determine the origin of post-exercise soreness.

In the field of pain research, saline injection has been approved as an experimental method.

This method of "sprinkling salt on wounds"

It strengthens pain in inflammation and wound areas.

By this way, we can determine the path of pain and clarify the origin and cause of pain.

Robert Schleip recalls：

I talked to the Danish scholar Thomas Graven-Nielsen about myofascial function. After the meeting, he changed his pain research design with Australian physiotherapist William Gibson. They first gave subjects pain from excessive leg movement, and then administered saline injections to both groups of subjects.

In the first group, saline injection was applied to deep muscles.

The second group was applied to the thigh muscle fascia.

The experimental design of the second group was added after discussion with me. The results are very clear. Subjects who received saline injection at the myofascial site felt more pain and more pain when they moved. That is to say, the pain of the second group was stronger after strenuous exercise. However, participants were unable to tell whether the pain originated from muscle tissue or myofascial tissue. They just feel "sore muscles". However, due to differences in the location of saline injection, the researchers were able to determine the origin of the pain.

Originally, the myofascial is the protagonist of pain after intense exercise!

Intense exercise results in changes or injuries to the fascia, resulting in a sense of pain. The results of this study caused a sensation in 2009 and were gradually adopted by the academic community. The pain is not in the red muscles, but in the white "deep fascia". This has been fully confirmed, but scientists are not yet sure whether the pain comes from a large number of receptors in the myofascial tissue. In addition, the theory of muscle fiber breakage has not been established.

The body aches for two or three days after strenuous exercise and then heals without medication. This suggests that the fascia adapts to new challenges and helps prevent or reduce the next general soreness.

The latest information shows that:

Muscular fascia research has rewritten some theories and proposed new prescriptions for exercise soreness.

Myofascial studies tell us how to prevent post-exercise soreness:

Maintain muscle and fascia health and vitality, exercise pain will not find you

This is also a good reason to encourage people to exercise their muscles and fascia.
