Junior high school students are the ones who grow physically. If you are not satisfied with your height, it is suggested to increase nutrition and do more exercise, such as skipping rope, high jump, running, etc., to stimulate the rapid proliferation of cartilage plates of long bones of limbs, which is conducive to growing taller. Stretching: pull-ups on the horizontal bar, aerobic exercise, etc. It helps to stretch the long bones of the spine and limbs and is beneficial to height. Systematic sports: such as basketball, volleyball and swimming. , are conducive to the secretion of growth hormone, increase appetite, is conducive to height growth.

Do the following exercises. The amount of exercise does not need to be too large, but it is important to persist. Simple pendulum and pull-ups can be hung by horizontal bars or doorframes. The height of the horizontal bar and the door frame should be hung on the bar with the body and the toes just off the ground. When hanging, hold the bar with both hands, the distance between the hands is slightly larger than the shoulder width, and the feet are close together, so that the body swings back and forth.

Note: the amplitude should not be too large and the time should not be too long. Arrange hanging pendulum every morning. When pull-ups, hold the bar alternately, inhale when pull-ups, exhale when falling, try to relax and stay 15 seconds. Boys do pull-ups 12 ~ 15 times each time, girls do them 2 ~ 5 times each time and 4 ~ 5 times a day.

You can jump up and touch a preset object (such as a branch or a brick on the wall) with both hands, or you can hang a ball under the football door frame and jump up and head the ball. Jump with your feet 10 times during exercise, and jump with your left foot and right foot 10 times after a short rest, 2 ~ 3 times a day.

In ball practice, we often do jump ball games and competitions, such as: actively grabbing rebounds when playing basketball, jumping up to shoot, jumping up to "block", and practicing spiking, blocking and diving to save the ball when playing volleyball; Do more jumping and heading when playing football.

Try to stretch your arms and legs in the water. When swimming breaststroke and freestyle, your upper arms stretch forward, and when swimming breaststroke, your legs kick backward. Swimming three times a week. Good habits, good figure and some life tips will make children grow taller.

The rules of life collected here are easy to practice. Life code 1: Children who get enough sleep and are in a period of vigorous growth and development will secrete a lot of growth hormone during sleep. According to the measurement, the growth hormone secreted in the sleeping state is three times more than that in the awake state. Try to let the children go to bed before 10 at night.

If you can sleep soundly, you can not only relieve fatigue, but also promote the secretion of growth hormone. It is necessary to get up on time in order to let children sleep soundly and form regular living habits. Rule 2: Growing up in the sun is closely related to the climate. Ultraviolet rays in sunlight can promote the formation of vitamin D in the body, and vitamin D can promote the absorption of calcium, which plays an important role in the development of bones.

Taking children outdoors or sunbathing is good for bone development. Rule 3: Insist on proper exercise, choose some exercises suitable for children's physical condition and physical strength, and stick to it, which is conducive to the development of bones.

For example, horizontal bar exercise is beneficial to the development of the spine and upper and lower limbs. In addition, jogging or high jump, long jump and skipping rope are also good for growth. Proper exercise for a while before going to bed, such as skipping rope 10 minutes, will make children secrete more growth hormone during sleep.
