How to Definite Winter Sports Activities
The first misunderstanding is that long-distance running can be an alternative to warm-up activities. Because of the stimulation of human exposure to cold air in winter, muscles, joint tissue activities are low; the flexibility of ligaments and stretching will also be significantly reduced. Without adequate warm-up activities, it is likely to cause muscle strain. It is not the whole story that if one wants to get a warm-up just through the method of running. The second misunderstanding is that light clothes do not mean good thing. Before exercise, the body is still at the room temperature and then strip too much cold air to the lungs and bronchi, and stomach has a negative stimulus. The most serious thing is that it can easily lead to disease.
The third misunderstanding is that vigorous exercise can exercise your body further. There are strict demanding of body flexibility and strength for Vigorous exercise and combat sports. If you take exercise in winter, you are more likely to injure, because the body is more rigid in winter. The fourth myth is that do exercise early in the morning does not mean getting good results. It is easy to come up with the phenomenon of inversion layer actually and it is not good for all kinds of harmful gases and dust to diffuse. In particular, before sunrise, there are more impurities and bacteria in the air. In this movement in the air for a long time, chronic respiratory diseases can be caused. Furthermore, cardiovascular function in six o'clock is worse, if there is cardiovascular disease, it will be easy-to-onset.
There is a fifth myth of winter sports, which is in order to run, snow and shine should be broken. There are fogs in winter mornings, now and then and the air is seriously polluted. You will suffer from the large number of dust, the pathogenic microorganisms if you go out and take exercise at this occasion, which will let your lungs inhale some harmful substances, also lead to chest tightness, difficulty breathing, serious can cause rhinitis, pneumonia, bronchitis, conjunctivitis and even cause disease, cardiovascular disease. So we can draw a conclusion that it will be better to run in a pleasant weather. If air pollution index is high, it is not suitable for outdoor exercise.
The sixth error is that it would be better if we do exercise indoors rather than outdoors in winter. To do sports at home is not an actually good choice in winter, because people used to shut down windows and doors in winter, which will make the air heavily polluted, although it is warm in rooms. Doing exercise out of the room is a good choice, because when our body subject to the cold air, our body resistance can be strengthened. In addition, the sunlight has disinfection effect to human body, still can promote body on the absorption of calcium, phosphorus. If the weather is not bad, pollution is not bad, it will be good for growing young soldiers to do exercise out of the room. The seventh misunderstanding is that physical exercise must be fast. In fact, the human body's muscle fiber is fragile; the bone density is also low in winter. Muscle strain and bone fiber fracture will appear through over exercise. The worst case may cause chronic muscle damage and even fracture.
