Will swimming and fitness have an effect? What is the reason? 1, getting better and better.
Friends who usually pay attention to swimming competitions will find that swimmers, both men and women, have particularly good bodies. Of course, this is related to the demand of athletes' material selection (generally, shoulder width, waist and thin legs are long, which is more in line with hydrodynamics and has little resistance in water), but it is also inseparable from the influence of professional swimming training all the year round on the body. Swimming requires both explosive power and aerobic endurance. At the same time, in order to better adapt to water, athletes have moderate subcutaneous fat, and the selection of materials requires shoulder width and leg length, so high-level swimmers are perfect.
Of course, for us ordinary people, it is difficult to reach the level of professional athletes and the training intensity can't match, but as long as you insist on scientific and reasonable exercise, your body will get better and better.
2. Aerobic endurance stands out.
Swimming is an aerobic exercise in water, and it is the key to effectively breathe while minimizing water resistance. Usually, swimmers in short-distance swimming events rarely breathe, or even don't breathe at all, but in events over 50 meters, regular and rhythmic breathing is particularly important. As a sport that requires high aerobic endurance, professional swimmers have strong aerobic metabolism and anaerobic metabolism and lactic acid resistance. So as long as you stick to the scientific and regular swimming, your heart and lung function will also be greatly exercised.
3. Buoyancy in water is the guarantee to avoid injury in sports.
As we all know, many sports may cause sports injuries as long as they are ignored for a long time. It is not uncommon for some antagonistic ball games to cause strain, sprain or even fracture, not to mention some aerobic sports without confrontation, such as muscle strain and joint pain caused by jogging. It has caused great trouble to our lives. On the one hand, these sports injuries are related to our unreasonable exercise mode, insufficient warm-up and inadequate sports protection. Another important reason is that when we exercise on land, we must fight against the weight, and the pressure of the weight itself on the joints is easy to cause strain. In swimming, because the buoyancy in the water offsets almost all the gravity of the human body, the joint pressure is very small when we exercise in the water, and there are few problems such as joint injury.
Therefore, swimming can not only improve people's immunity and cold resistance, but also improve people's cardiopulmonary function. Because breathing is restricted during swimming, the vital capacity will be greatly improved during swimming, and swimming is a very good aerobic exercise. When swimming, you can achieve a very good aerobic exercise effect by controlling the intensity and time, and the water temperature is lower than the human body temperature, which can also improve the cold resistance and enhance the resistance.
