What effects does the cold environment have on human movement?
1, muscle tension
When you walk out the door and are blown by the cold wind, you will feel muscle tension. Muscles contract when they are cold, which limits your range of motion and makes it a little difficult for you to exercise. Sports physiologists suggest that people do some short-term warm-up exercises indoors first to offset the muscle tension effect.
2. Blood flows into the body.
When the weather is cold, the primary task of the human body is to protect organs. This means that blood will flow from the limbs to the center of the body, which is why it is difficult to keep warm with cold hands, feet and even face.
3. The heart rate response has changed.
When the weather is cold, the blood delivered by the heart to the skin and limbs decreases, and the heart rate slows down to reduce the response to the cold. When you start to move your body, your heart must work harder to keep warm and make blood flow to the working muscles, so your heart rate is higher than that in warm weather when you do the same amount of exercise.
Matters needing attention in exercise in cold environment:
1, windproof and sweat-wicking: When you go out, you should not only pay attention to windproof and warmth, but also pay attention to the breathability of clothes. Don't run out in a sweat, and then "lose the temperature and become messy" in the wind. It is recommended to match the kind of sports underwear, which has good breathability and sweat absorption.
2. Pay attention to "sweating" first: stay for at least 5- 10 minutes after stretching before changing clothes. When leaving, pay attention to buffer 1-2 groups at the indoor and outdoor junction before going out.
3, pay attention to running snow outdoors: try to wear non-slip running shoes with large soles and deep gullies. If the bottom is too high, pay attention to the occurrence of ankles during running. Pay special attention to foot frostbite and warm up before going out for a run. If you feel your feet are frozen after running, don't brew hot water immediately. First of all, relieve the feeling of freezing at room temperature, exercise and let the blood flow as much as possible.
4, pay attention to the whole body to keep warm: If you have a small partner with stubborn foot disease before, you should do a good foot check when running in cold weather to avoid "one foot is sick." Keep your head warm, and you must have masks, thread caps, fleece running caps and headscarves.
