From the point of view of nervous system, stretching muscle can change the excitability of the corresponding center, block the spasm caused by excessive muscle excitement through negative stretching reflex, and improve the local tissue ischemia caused by spasm, thus improving the blood flow of muscle and promoting the recovery of damaged tissue. At the same time, static stretching can improve the excitability of sore muscles. Repeated use of the method of extending muscles immediately after exercise to before muscle soreness is more effective in relieving muscle soreness.
2. Relieving method: Hot compress can also improve blood circulation, relieve muscle spasm, and is conducive to the regeneration and repair of damaged tissues. Some people also use local massage and electrotherapy to relax muscles, promote tissue metabolism and achieve the purpose of relieving muscle soreness.
I hope I can help you and adopt it.
