Modern scientific research has shown that scientific exercise is important for the prevention and treatment of “three highs”. Especially recommended moderate intensity aerobic exercise, more benefits. 1, what is aerobic exercise: aerobic exercise is any rhythmic exercise, the exercise time is long (≥ 15 minutes), the intensity of exercise in the medium or medium intensity. Acceptable exercise programs in daily life are: walking, jogging, cycling, swimming, aerobics, tai chi, table tennis, bowling, badminton, etc. 2, how to judge their own exercise has reached the medium intensity and the amount of grasp: ① sports center beat faster, slightly sweating, self-feeling a little tired; exercise respiratory rate accelerated, slightly shortness of breath, can talk to people, but can not sing; exercise can be evil heart rate, the fastest heart rate per minute does not exceed “170 – actual age” is appropriate; ② exercise after the end of more than about 10 minutes after rest heart rate back to normal levels, otherwise, attention should be paid to whether the exercise intensity is too large. ③ exercise time is generally more than 3 times a week, at least 30 minutes each time. 3, what time period is the most appropriate exercise: early in the morning is a high incidence of cardiovascular and cerebrovascular events, general blood pressure is also high, so it is recommended that the “three high” people avoid the early morning, choose the afternoon or evening exercise. 4, matters needing attention: ① exercise therapy is an important adjunct in the treatment of “three highs”, not a substitute for standard drug therapy. For example, exercise is not recommended when blood pressure exceeds 160/100mmHg. Severe advanced diabetic retinopathy is also not recommended. ③It is necessary to warm up for more than 10 minutes before each exercise, and to cool down for more than 10 minutes after the exercise. It should be done gradually and not in a hurry. For overweight people, it is recommended to walk fast at first and slowly transition to jogging. ④ Exercise such as any discomfort such as abdominal pain, chest pain, dyspnea, shortness of breath, angina attack, etc. should immediately stop, if necessary, seek medical attention, do not brace yourself. In fact, the above exercises are also applicable to healthy people.
