As the saying goes, life lies in exercise, which is true at all. Moderate exercise can improve cardiopulmonary function, promote systemic blood circulation and relieve nervous mood. However, there must be a degree in everything, and the same is true for sports. You need to choose the right sports according to your own situation, and you can’t blindly pursue quantity and duration. If the amount of exercise is insufficient, the body function will slowly deteriorate; Excessive exercise will cause persistent muscle pain, irritability and loss of appetite, and at the same time, it will also reduce immunity and increase the damage to bones and joints.
1. Exercise intensity
Exercise intensity, as its name implies, is the strength spent in exercise, which is determined by the type and purpose of exercise. There are different ways to measure the intensity of exercise, such as jogging or brisk walking. The intensity is measured by the target bull’s-eye rate and based on the maximum heart rate, which is equal to 220 minus age. The bull’s-eye rate of moderate and high-intensity aerobic exercise ranges from 60% to 80% of the maximum heart rate, and strength training needs to measure the exercise intensity by weight and repetition times.
2. Motion frequency
Exercise frequency refers to the interval time of exercise, and the optimal frequency is determined by the type and purpose of exercise. If the purpose of exercise is to lose weight, at least 300 minutes of moderate and high-intensity aerobic exercise a week can reduce weight and body fat; If the purpose of exercise is to maintain good health, you need to have 150 minutes of aerobic exercise a week, and then match it with 2~3 days of strength training.
3. Exercise time
Exercise time refers to the duration of exercise, which is determined by the type of exercise, the purpose of fitness and the level of exercise. At the beginning, you can do aerobic exercise first, and the exercise time is about 15~20 minutes, and the exercise intensity is well controlled; If you want to enhance flexibility through exercise, make sure that each muscle group stretches for about 15 seconds and repeat it three times; If you want to enhance your cardiopulmonary endurance, the duration of high-intensity exercise should not be less than 20 minutes.
4. Type of exercise
There are many types of sports, such as aerobic training, flexibility and resistance training, etc. The specific types of sports are divided into cycling swimming, weightlifting and running, squat and so on. You need to choose the right type of exercise according to your own sports purpose.
1. Moderate intensity exercise
Moderate intensity exercise is equivalent to brisk walking for half an hour to an hour every day. Such activities include walking, shopping, housework and gardening. You can walk more in your daily life for at least half an hour every day.
2, high-intensity aerobic exercise
Common high-intensity aerobic exercises include climbing mountains, swimming and jogging, climbing stairs and aerobics, etc. Exercise at least 3~5 times a week for no less than 20 minutes each time to ensure that the exercise heart rate needs to reach the target heart rate.
3, high-intensity competitive sports and leisure sports
Such sports include basketball, football or tennis, as well as dancing, skating and skiing. Such sports can not only improve heart and lung function, but also cultivate sentiment. Obese or overweight people can choose swimming, which can reduce the joint load.
4, muscle fitness exercise
This kind of sports have their own weight-bearing resistance training, as well as resistance training by equipment, such as dumbbell weight-bearing and elastic belt exercises, which are done at least 2~3 times a week.
5. Flexible exercise
Flexibility exercise includes practicing yoga, dynamic stretching or static stretching, which can be arranged after aerobic exercise or resistance training for 15~30 seconds each time.
Adults should exercise at least 30-60 minutes every day, and at least 150-300 minutes of moderate-intensity exercise every week. Try to arrange the winter exercise time at noon or afternoon, and the morning exercise time should not be too early, at least after the sun comes out.
