Because the functions of all aspects of the body are not suitable at first, muscle aches after exercise are generally due to relatively excessive exercise, which exceeds the intensity of aerobic exercise. After intense muscle contraction, the lactic acid produced can not be further decomposed into water and carbon dioxide in a short time, and insufficient oxygen supply forms anaerobic metabolism, which leads to a large amount of excessive lactic acid accumulation in the body, which in turn leads to muscle soreness. This situation is a relatively normal physiological reaction. You should stop exercising and let your body have a full rest and relaxation. In addition, you should avoid large-scale activities in a short time and do no heavy physical labor to help eliminate discomfort. You can also use kneading, pressing or pushing to promote muscle relaxation. At the same time, some lavender essential oil or chamomile essential oil can be used to improve the efficacy of massage, especially to improve the catabolic probability of lactic acid and promote the repair of damaged tissues.

Pressing the affected area with ice cubes or cold towels can reduce blood circulation. After 24 hours, you can use a hot towel or hot water bottle to help relieve it, but be careful not to burn your skin.

Drugs with the functions of relaxing muscles and tendons, promoting blood circulation, relieving pain and diminishing inflammation can be used externally, such as Yunnan Baiyao aerosol, safflower oil, relaxing muscles and activating blood ointment, etc., but they need to be used under the guidance of professional doctors.

Finally, you must do enough warm-up activities before the start of fitness, and you can choose to do muscle stretching or chest expansion, which can effectively avoid muscle injury and reduce the occurrence of soreness.
