The Limbering-up Trainings
When you dress in the clothes that you want to wear in the running and set to begin to run, wait a minute, you must not run. Your feelings may have been prepared well to run, yet your body is still not complete. It may not be proper to do the sports if you do not do anything for one day. Before you set out to run, you have to warm up the body well, it is the produce of the limbering-up exercise. The limbering-up exercises can increase the erythrism of the significant anxious system, adjust the bad state before the race, speed up the reply speed of the brain, and prepare for the race.
However, some people thought that the prepared exercises was not important. When you had deep understanding of the running, you would find that people had the opposite views on all aspects of the running. The limbering-up exercises had a magical factor that Vaughan Thomas wrote in Science and Sports. His implication was that they would have some benefits. Yet, the payback were not so many as people considered widely. He said that the warming-up exercises might enrich the function of the organ and won the race, yet in most cases, the player would fail as the warming-up exercises used up the natural power. His words are perhaps right. Yet the limbering-up exercises were still significant in some ways, therefore we should pay attention to them.
The cardiologist, Dr. Paul Act, who had introduced in chapter III said, the warming-up exercises might promote blood movement and increase in intensity the body temperature, thereby rise the reduction task of the muscles. He wrote in the article which was published in “American Physical Therapy”, for the middle-aged and older people, enhancing the blood circulation of coronary artery was particularly significant. Your heart might not get enough blood at the starting of the strenuous exercises if you did not do the limbering-up exercises in advance. Dr. James Barnard who studied in the School of Medicine, University of California, Los Angeles agreed with the agreement of Act. While forty-four healthy man whose age were from twenty-one to fifty run on the rapid rotation of the running machine, more than two thirds of the people appeared abnormal ECG. On the contray, before running on the treadmill, in the first two minute, if you did the limbering-up exercise, almost all the ECG anomalies would disappear or reduce. Because the body became flexible as a result of the limbering-up exercises. Running did not do well in promoting the flexibility just as what was mentioned in the third chapter. For example, running in enhancing the flexibility was poorer than swimming, handball, tennis and a bit better than walking, golf and bowls. Some people’s muscles were tight due to running frequently, especially the calf. The reason was that the rage of the muscles movement was small and you were always repeating the same action when you were running. You might run or jog, walk on the uphill or walk on the downhill, and additional different kinds of running so that the rage of the muscles movement would be increased, but you still need to do the exercises for the sake of increasing the flexibility.
