The first symptom of excessive exercise is sports injury, including muscle soreness, bone pain or joint injury, and even serious joint effusion and ligament strain. In addition, excessive exercise will increase the burden of human heart and lung function, and even cause palpitation, chest tightness and even myocardial ischemia. In patients with excessive exercise, if a large amount of lactic acid is accumulated due to anaerobic metabolism of muscles, it will also increase the burden on the kidneys, which will seriously lead to acute renal failure, hematuria, oliguria and anuria. Therefore, the amount of exercise should be gradual and not excessive, especially for patients with cardiovascular and cerebrovascular diseases or kidney diseases.
