After exercise, the sore thigh muscles often start gluconeogenesis and glycolytic pathway because of excessive exercise or anaerobic exercise, at this time, too much lactic acid will be metabolized, and lactic acid will gather in the inner thigh, causing thigh muscle pain. You can use the following four methods to relieve it: First, you can apply relaxation or stretching. Some soothing exercises after aerobic exercise, such as Pilates or yoga, are helpful for the recovery of the nervous system and the release of excess lactic acid in the thighs. Secondly, physical acid removal methods can also be used, such as microwave physiotherapy instrument or ultrashort wave physiotherapy instrument, which can remove lactic acid cooperatively. Third, you can also use the method of massage, from the hip sciatic nerve, from the anterior superior iliac spine to orthopedics, from outside to inside and from top to bottom, to make the skin slightly red and sweaty, which proves that lactic acid is discharged.
