What is the lung capacity of primary school students?

Many of us know that primary school students have their vital capacity tested during their annual physical examinations to determine the child's lung development. Once the vital capacity is low, a little exercise can easily lead to hypoxia and other phenomena, and when you have a cold or fever, it is easy to develop pneumonia, which is particularly detrimental to lung health. If we have a good grasp of normal vital capacity, once we find that our lung capacity is low, we can get a good improvement by doing more physical exercise. Let's take a look at what the vital capacity of primary school students is.

What is the lung capacity of primary school students?

Average reference value of vital capacity for primary school students:

You may want to try the following methods of using breathing to increase your lung capacity. ?

1. Deep breathing method: First, inhale slowly through the nostrils to fill the lower part of the lungs with air. During inhalation, the abdomen will slowly bulge as the chest cavity lifts upward and the diaphragm moves downward. Then continue to inhale to fill the upper part of the lungs with air. The ribs will then lift up and the chest cavity will expand. This process usually takes 5 seconds. Finally hold your breath for 5 seconds. After a period of practice, you can increase the breath-holding time to 10 seconds or even more. After the lungs have absorbed enough oxygen, exhale slowly, and the ribs and sternum will gradually return to their original positions. After pausing for one or two seconds, start again from the beginning and repeat for 10 minutes. After practicing for a long time, it can become a normal breathing method. ?

2. Quiet breathing method: Press the right nostril with your right thumb, and slowly take a deep breath through the left nostril, consciously imagining that the air is flowing towards the forehead. When your lungs are saturated with air, press your left nostril with the index and middle fingers of your right hand, hold your breath for 10 seconds and then exhale. Then start again by holding the left nostril. Do 5 times on each side. ?

3. Sleep breathing method: Lie on the bed, place your hands flat on both sides of your body, close your eyes and start taking deep breaths. Slowly raise your arms above your head, close to your ears, with your fingers touching the headboard. This process takes about 10 seconds, and both arms are restored at the same time, and repeated 10 times. This method can also help you fall asleep peacefully.

4. Exercise breathing method: Actively increase your breathing volume while walking or jogging, inhale slowly and exhale quickly. When inhaling slowly, slowly expand your chest as you inhale, and exhale quickly. Do not exercise less than 20 times each time, and you can do it several times a day.

The above is an introduction to the lung capacity of primary school students. If your child’s lung capacity is low, don’t worry or be afraid too much, because lung capacity can be improved through exercise. For example, long-term swimming or running can greatly improve lung capacity, which can also improve physical fitness and make the body healthier.
