Body aches after exercise

Introduction

Introduction Body aches are people who do not exercise regularly. After participating in more intense exercise, local muscles sometimes have soreness. When people exercise vigorously, the muscle glycoprotein is decomposed faster, and the oxygen consumption is increased, so that the muscle is temporarily in a state of relative hypoxia. At this time, the muscle glycogen can be converted into lactic acid by the pyruvate and accumulated in the muscle. Lactic acid accumulates in the muscles, which stimulates the chemoreceptors in the muscles to produce excitement, and the excitement is transmitted to the cerebral cortex, causing a sore feeling. At the same time, due to the accumulation of substances such as lactic acid, the osmotic pressure in the muscle is increased, and the absorption of more water in the muscle tissue causes local swelling, and a feeling of soreness is also generated.

Cause

Cause

The cause of this phenomenon is generally thought to be related to energy metabolism inside the muscle. We know that muscle contraction requires energy; energy is provided by the breakdown of muscle glycogen in muscle tissue. In the case of sufficient oxygen supply, such as when the muscle is at rest, the muscle glycogen can be directly decomposed into carbon dioxide and water by pyruvate and release energy. However, when people exercise vigorously, the muscle glycoprotein is decomposed faster, and the oxygen consumption is increased, so that the muscle is temporarily in a state of relative hypoxia. At this time, the muscle glycogen can be converted into lactic acid by the pyruvate and accumulated in the muscle. Lactic acid accumulates in the muscles, which stimulates the chemoreceptors in the muscles to produce excitement, and the excitement is transmitted to the cerebral cortex, causing a sore feeling. At the same time, due to the accumulation of substances such as lactic acid, the osmotic pressure in the muscle is increased, and the absorption of more water in the muscle tissue causes local swelling, and a feeling of soreness is also generated. Another explanation for causing muscle hypoxia is exercise muscle fatigue, due to insufficient relaxation of local muscle fibers, resulting in slight paralysis, blood vessels in the muscles are oppressed, blood flow is blocked, causing muscle ischemia and hypoxia, at this time, muscle Hard and sore feeling.

Routine medical examination

The body can be diagnosed with pain after exercise. Chronic soreness in the muscle often occurs between 24-48 hours after training. The degree of chronic soreness in the muscle is related to the shape of muscle contraction. Centrifugal contraction is most likely to form chronic soreness of the muscle, and isotonic contraction is the least significant. When the muscles have chronic soreness, the muscle strength is significantly reduced. When exercising, the supplemental energy should use sugars that are easily oxidized and decomposed. Such as banana honey raisins, etc., protein metabolism during exercise, should pay attention to timely add protein after exercise to prevent the occurrence of sports anemia. If it is super-strength exercise, special attention should be paid to the supplement of salt and calcium, which can restore the hydrogen ion concentration and osmotic pressure disorder in the body and relieve muscle fatigue.

Diagnosis

Differential diagnosis

Should be differentiated from cervical spondylosis, low back pain and other bone injury diseases.

Self-identification of strain and muscle aches:

Muscle and ligament strains can suddenly appear due to a damaging movement, while muscle soreness is gradually aggravated. There is a way to identify both: muscle soreness can be alleviated by stretching, and if it is a sports injury, pulling will increase the pain.

In short, muscle soreness and muscle (or ligament) damage properties after exercise are completely different. Muscle soreness can be alleviated by rest, stretching, massage, etc. Muscle (or ligament) damage must be solved by medical means.
