First, why are there muscle strains and muscle aches? ① Causes of muscle strain
Muscle is composed of muscle fibers, which are different from ordinary cells, and they are dozens of times longer than ordinary cells. We usually need the contraction and relaxation of muscle fibers to drive the movement of bones, thus driving the movement of the body, so if we carry out large-scale exercise training at ordinary times, it is easy to cause muscle strain.
② Causes of muscle soreness
Muscle fiber is also a cell, but cells will inevitably carry out anaerobic exercise. The lactic acid produced by anaerobic exercise will make our body feel sore. The efficiency of anaerobic exercise is far lower than that of aerobic exercise, so it is easy to feel weak when training for too long. Muscle fiber is a cell with strong metabolic ability, so the lactic acid produced by anaerobic respiration during exercise is also huge.
Second, I clearly made preparations, why is the muscle still so painful? ① The preparation work is incorrect.
After getting ready, muscle strain and muscle ache still appear after exercise and fitness, which may be caused by your inadequate preparation, failure to take it seriously, or incorrect exercise preparation, so you must pay attention to the preparation before training.
(2) Irregular fitness movements and training habits.
For example, when running, striding your legs is easy to cause muscle strain. When the long jump falls to the ground, the legs are not cushioned, and it is easy to cause muscle strain, which may lead to bone damage.
③ Overload exercise
Overworked exercise will definitely lead to muscle aches. Our bodies have their limits. When the breathing state of our muscles changes from aerobic to anaerobic, we can stop training. Besides, overloaded exercise can not only make you exercise more effectively, but also increase the burden on your body, or even worse!
