It's very cold in winter, and sometimes there will be sandstorms. If you breathe with your mouth open while running, cold air directly stimulates the mucous membranes of the mouth, throat and trachea, making the mucous membranes of these parts dry and uncomfortable, which will cause cough. Usually, people breathe through the nose, but when running, because of the intense muscle activity, the required oxygen is greatly increased, so they have to use their mouths to help them breathe. So when running in winter, try to breathe through your nose, or breathe in a mixed way. At this time, the mouth should be half open, the mouth slightly open, the tongue raised, and cold air inhaled through the teeth, so that cold air has a warming process in the mouth. Breathing through the nose at the beginning of running and breathing through the mouth after getting used to it can also avoid cold air directly irritating the mouth, and the phenomenon of coughing will be reduced and avoided.
The correct running movements should be: slightly lifting shoulders, bending arms 90 degrees, slightly swinging back and forth and slightly bouncing up and down, slightly lifting shoulders, raising thighs before running, fully pushing back, and striding forward with great flexibility. This can make the abdominal muscles tense, the abdomen lift up, and the breathing is even, slender, full and rhythmic. When running, the abdominal muscles should be properly tense, and pay attention to lifting gas. This itself is the training of respiratory organs and the exercise of abdominal muscles, which enhances the control of abdominal muscles and is also an effective fitness method.
Try to step on the ground with your front foot instead of your heel. However, when running, we need to jump the whole person with all the muscles in our legs.
Although the front thigh muscles are mainly used, calf muscles are inevitably used. After running, you can do some stretching exercises to relax your tight muscles.
