I don't know if you did aerobic exercise and muscle stretching after fitness. If there is no stretching. The picture below shows some local stretching of the upper body, which can relieve pain.
Latissimus dorsi stretching
Stretching:
Left and right sides, two groups on each side, each group 15s.
musculus pectoralis major
Stretching:
Left and right sides, two groups on each side, each group 15s.
abdomen
Stretching:
Two groups, each group 15 seconds. The first group takes a break of 5 seconds and starts the next group.
The next day. Yes, but in the past, I could only do simple aerobic exercise to relieve the accumulation of lactic acid in muscles. Such as a treadmill,
Training:
Low speed, long training. (7 to 8 speeds, 30 minutes to 1 hour)
Extended data:
Lactic acid is an intermediate product produced in the process of glucose metabolism during exercise. Due to relatively excessive exercise, which exceeds the intensity of aerobic exercise, lactic acid produced in the body cannot be further decomposed into water and carbon dioxide in a short time, and insufficient oxygen supply forms anaerobic metabolism, resulting in a large amount of excessive accumulation of lactic acid in the body. Lactic acid accumulation can cause local muscle pain.
Lactic acid accumulation usually occurs. If you want to accelerate the excretion of lactic acid, one is continuous aerobic exercise to accelerate the excretion of lactic acid with energy metabolism, and the other is fumigation with hot water (such as sauna) to accelerate the excretion of lactic acid. However, relatively speaking, aerobic exercise is more scientific and beneficial to the body.
