Now people realize the importance of exercise. Some people mistakenly believe that the more exercise the better. They don't care about how their bodies feel. The more sore your body is, the more effective it is. There are also some dieters who always abuse themselves to exhaustion and exhaustion in order to lose weight at once. As everyone knows, this kind of high-intensity and too frequent exercise has actually damaged the body.
Mr. Wang tasted the bitter fruit of excessive exercise. Mr. Wang is 45 years old. When a man reaches middle age, he feels his health is not as good as before. In order to keep healthy, he became a sports enthusiast. He either goes to the gym or runs in the morning every day, and even falls in love with marathon running.
Exercise really makes Mr. Wang feel strong, but recently Mr. Wang's knee joint always hurts and will rebound. Mr. Wang doesn't know what happened to his knee, so he must have it examined. This investigation turned out to be a knee injury caused by excessive exercise.
It can be seen that if you exercise too frequently, it will also bring harm to your body. Let's take a look at the experts and talk about the harm caused by excessive fitness exercise.
Excessive exercise will do harm to the body and joints.
When we exercise, there will be some friction in the joints of the whole body. The friction within the normal range is acceptable to the body, but excessive exercise will cause joint wear and tear, thus damaging the joint parts.
2, premature aging
Moderate exercise is beneficial to the recovery of blood pressure and cardiac function, and reasonable exercise is beneficial to patients with early hypertension. However, patients with hypertension or heart failure are very weak, and excessive exercise beyond the heart's endurance will aggravate heart damage.
During exercise, people's heart rate will increase, and the heart will bear certain pressure. If they exercise for too long, the load on their hearts will exceed the load, leading to heart disease and heart failure.
3, affect hormone secretion and metabolism
When the body exercises excessively, the function of the pituitary gland will decline, and the hormones secreted by the body are mainly controlled by the pituitary gland. When the function of pituitary gland declines, it will affect the secretion of hormone level and decrease the metabolic level, so it is easy to get tired, muscle recovery is not good, and cramps often occur, which will reduce the effect of increasing muscle and reducing fat brought by fitness.
4, increase the possibility of physical injury
When exercise exceeds the endurance of the body, with the extension of exercise time, people will feel more tired, the function of cerebral cortex will decrease, the human body will become dull, the ability to judge things will decrease, the energy will be difficult to concentrate, the movements will be uncoordinated, and mistakes and injuries will easily occur during exercise.
What kind of exercise is the right amount? First, exercise should be moderate. Exercise more than three times a week and do moderate-intensity exercise for more than 30 minutes each time. This amount of exercise is relatively moderate. Everyone can make the most appropriate amount of exercise according to their physical condition and age.
Secondly, the heart rate should be standard. We can infer whether our exercise is appropriate according to the fatigue and heart rate after exercise. I feel a little tired during exercise. 60% to 70% of the maximum heart rate is effective exercise, which is most suitable for health.
Finally, exercise should be divided into age groups. People under 40 need to keep exercising, while people over 60 need maintenance instead of exercise.
Be sure to remember that you should do your best according to your physical condition when exercising. If we feel tired, we should have a proper rest. Don't wait until our bodies can't move at all, which will do great harm to our bodies.
