Are You Worry about Running

The "Foot and Ankle Research" magazine has published a new study and found that when people wear shoes, their steps will be much larger than that of barefoot. There will be greater force on heels when there is touchdown on the ground from foot. One Harvard University Human Evolutionary Biology professor called Daniel E Li Boman has completed a study. It was found through the comparison between primary and middle school students who used to wear shoes in cities and countryside students who used to walk to school on barefoot that when city students run, the touchdown point of foot will focus on heels when foot touch down the ground. The touchdown point of foot of countryside students, however, was going to mainly focus on foot's front parts. They not only would produce apparent impact, but also would touch down the ground lighter.This research showed that barefoot running is better for human bodies. Because there will be less damage while there is smaller impact force. Scientists believed that human beings are born to be suitable for running on barefoot. Some dangers, such as stress fractures and muscle or tendon injuries will be increased naturally with slightly inappropriate actions, so the method is very important. Many people would like to worry about the hurt that running will bring to knees, and then induce arthritis. A research has been released by the American "National Public Radio" in recent days that it has been found that running will be beneficial to joint health instead. Swedish researchers have selected a group of people who get arthritis risk to run everyday, and the other group of people will not run.The NMR imaging technology showed that runners' cartilage health has been improved significantly. This suggested that running is conducive to joint health. It was said by David Phil Johnson who was a Boston University School of Medicine epidemiologist expert that part cartilage loss will happen every year when people get to a certain age, for example, forty-year old. There will be healthy cartilage and joints if there is nothing wrong with your knees and in a week you can run five to six times with a proper speed. But it should be noted that if your knees have been injured, or you have ever received knee surgeries and run with incorrect postures, and then the arthritis risk will be increased.In the second place, people had better not run intensely if they overweigh nine kilograms. Or it will force knees to inflame, form bone spurs and accelerate cartilage loss. It is right to run with the posture of head up and be with straight and relaxed back. Knee joints ought to be bend slightly when foot falls to the ground. There had been appropriately ninety degrees to arm bend and spread arms to the greatest extent. What is more, we should select running programs, which are proper. In elementary stage, for instance, we can run five kilometers with ten to twelve weeks, run ten kilometers with six to eleven weeks in and intermediate stage and run ten kilometers with eleven weeks in senior stage. 800x600 Normal 0 7.8 Å 0 2 false false false EN-US ZH-CN X-NONE MicrosoftInternetExplorer4 /* Style Definitions */ table.MsoNormalTable {mso-style-name:nh<; mso-tstyle-rowband-size:0; mso-tstyle-colband-size:0; mso-style-noshow:yes; mso-style-priority:99; mso-style-parent:""; mso-padding-alt:0cm 5.4pt 0cm 5.4pt; mso-para-margin:0cm; mso-para-margin-bottom:.0001pt; mso-pagination:widow-orphan; font-size:10.0pt; font-family:"Times New Roman","serif";}
