The size of your vital capacity determines your explosive power.
In other words, your muscle type determines your vital capacity.
If your vital capacity is not large, it means that you have more red muscle fibers than white muscle fibers.
In other words, your endurance is stronger than your explosiveness.
More red muscle fibers determine that your hemoglobin is higher than that of people with more white muscle fibers.
This means that you have more red blood cells than him under the same blood volume.
The more red blood cells, the greater the oxygen carrying capacity of blood.
However, we know that the oxygen you inhale in one breath may not be fully absorbed by the lungs, mixed with blood and brought to the whole body organs. There will be a small amount of oxygen in your breath.
But your oxygen carrying capacity is greater than that of people with high lung capacity, so you don't need to inhale more air.
So the size of your vital capacity has a lot to do with your muscle type.
You got it?
It is also related to your physical fitness, cardiopulmonary function and age.
Also, there will be no people with good endurance and explosive power in the world. Some people have good endurance, while others have good strength.
Therefore, in world-class track and field competitions, you will see that some people use the lead to drag down their opponents with endurance, while others use the follow-up to save their physical strength and give play to their advantages to surpass their opponents in the sprint stage.
Running can improve your heart and lung function, but your vital capacity will not be significantly improved.
Don't believe it? I used to be a long distance runner. After practicing long-distance running for so many years, my lung capacity hasn't improved much.
