Online Class Notes (Jesse) [30]

It’s worth noting that serious local ischemia happened in a short time will induce irreversible damage to cells. Besides, excessive exercise also lead to renal failure by the contraction of renal blood vessels, obstruction of renal tubules, and the damage in tubular epithelial cells.

Thirdly, excessive exercise does harm to heart. Right atrium, right ventricle and cardiac muscle tissue under the inner membrane are the most easily damage location. Because of the disturbance of calcium ion, the activity of enzyme inside the mitochondria enhances, changing the permeability of mitochondria membrane and thus causing damage to cardiac muscle. It also indicates that cardiac ischemia reduce the supply of oxygen to the heart and influence its energy metabolism, which might put us in danger.

Since the body function differs from one another, the scientific and reasonable exercise plans for everybody are differential. If the acute fatigue phenomenons such as muscular pain and the soreness and weakness of waist and knees occurs and fail to be recovered until the next exercise, it’s time to reduce exercise or stop it. If the reaction ability drops and the sense of balance decreases after exercise and can not be recovered in time, it’s necessary to see a doctor promptly.

It’s worth noting that sudden serious local ischemia will induce irreversible damage to cells. Furthermore, excessive exercise may also lead to renal failure resulting from the contraction of renal blood vessels, obstruction of renal tubules, and damage of tubular epithelial cells.

Thirdly, excessive exercise may harm the heart. The right atrium, right ventricle, and cardiac muscle tissue under a inner membrane, are locations most prone to damage. Due to an imbalance of calcium ion, the activity of enzymes inside the mitochondria increases, altering the permeability of the mitochondria membrane and thus causing damage to the cardiac muscle. It also indicates that cardiac ischemia reduces the supply of oxygen to the heart and impacts its energy metabolism, which is potentially fatal.

Since the way each person’s body functions is different, exercise plans will vary from person to person. If symptoms of acute fatigue such as pain and soreness in the muscles, lower back, and knees occurs and remains until the next exercise, it’s time to reduce or cease exercise. If agility and sense of balance reduces after exercise and does not recover within a reasonable period, it may be necessary to consult a doctor promptly.
