Who should not do strenuous exercise?

Exercise and fitness can ensure a person's health, but strenuous exercise can achieve the greatest fitness effect. However, there are many patients in life who cannot do strenuous exercise. What kind of people are not suitable for strenuous exercise? If such people do fitness, how much harm will it cause to the human body? The following will give friends a detailed introduction to see which type of people in life are least suitable for strenuous exercise.

1. Congenital heart disease

After a doctor diagnoses a child with congenital heart disease, the child should never be allowed to do strenuous exercise, otherwise it will put a greater strain on the heart, leading to serious consequences.

2. Heart disease

(1) Patients with rheumatic heart disease should not participate in strenuous exercise, otherwise it may aggravate the disease or cause heart failure.

(2) Patients with coronary artery disease should not engage in strenuous exercise, as it may induce angina pectoris, new infarction, severe arrhythmia, or even sudden death.

(3) Patients with myocarditis should not engage in strenuous exercise. This is because patients with myocarditis may induce heart failure or severe arrhythmias during exercise. Another thing to remind you is that a cold may also cause myocarditis, so you should not engage in strenuous exercise after a cold.

(4) Patients with arrhythmia. Patients with arrhythmia are not suitable for strenuous exercise because strenuous exercise will greatly increase the burden on the heart, making the diseased heart unable to bear it, aggravating the arrhythmia and heart failure, or even causing sudden death.

3. Hypertension, cerebrovascular disease

If patients of this type exercise vigorously, it will directly lead to high blood pressure, or excessive blood flow to the brain, causing blood vessel rupture, etc. The risk caused is quite high. So, if you want to choose to exercise, it is better to choose gentle exercise. Vigorous exercise is not suitable for you.

4. Diabetes

There are some requirements for exercise for diabetics. They should do it according to their own conditions. Excessive exercise may cause lactic acid accumulation. In severe cases, lactic acidosis may occur, which in turn stimulates the muscle nerve endings and produces a feeling of soreness. People who cannot control their blood sugar should not engage in strenuous exercise. This will cause your blood sugar to fluctuate too much during strenuous exercise and lead to accidents. Of course, people who do not usually participate in sports should also increase the amount of exercise slowly when choosing to do it, and should not do strenuous exercise at the beginning.

Experts recommend that diabetics should focus on moderate-intensity aerobic exercise and combine it with low-intensity strength training to achieve better exercise and blood sugar-lowering effects.

5. Arthritis

There are many types of arthritis, but their pathological mechanisms are basically the same, that is, due to strain or inflammation of the joint tissue, local physiological lesions occur, which eventually lead to functional disorders and a decline in the functional condition of the whole body. Therefore, people with arthritis should not participate in strenuous exercise. At this time, the damage to the joints has not yet recovered, the functions of the muscles and ligaments are still in a very poor state, and the joint capsule is loose; at the same time, the nutritional metabolism and metabolic functions of the damaged joint tissue are very weak, which determines that the diseased joint tissue cannot adapt to the load brought by strenuous exercise. Although the pain and soreness of the affected joints can be somewhat eliminated when the exercise load is relatively small, these symptoms will reappear or even worsen after the exercise. This shows that strenuous exercise and heavy loads can only aggravate the strain and pathology of the diseased joints, which is extremely detrimental to the recovery of the diseased joints.

6. Severe myopia

High myopia refers to more than 6 diopters (commonly known as 600 degrees). People with severe myopia should not engage in strenuous exercise, mainly to avoid retinal detachment. It is generally believed that the greater the degree of high myopia, the more obvious the changes in the fundus are and the greater the possibility of retinal detachment. Some people even believe that more than 5% of people with high myopia may develop retinal detachment, which means that the probability of retinal detachment in people with high myopia is high.

The types of people mentioned above are not allowed to do strenuous exercise, because strenuous exercise is very harmful to the human body. Even long-term strenuous exercise can cause the loss of a person's life. Therefore, when doing strenuous exercise, you must pay attention to your body. Once you belong to the types of patients described above, you must be careful about the way you exercise.
