David Phil Johnson was Nike Tns Sale an epidemiologist expert of Boston University School of Medicine, and it was said by him that when people reached to a certain age, such as forty years old, and then cartilage will lose a part each year. 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. Otherwise, inflammation of knees will be forced to produce, bone spurs will be formed and cartilage loss will be accelerated.

It is right to run with the posture of head up and be with straight and relaxed back. When feet touch down the ground, knee joints should be bend slightly. 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. For example, run five kilometers with ten to twelve weeks at the Nike Air Max Plus Tn beginning, run ten kilometers with six to eleven weeks in intermediate progress, and run ten kilometers with eleven weeks at last. 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.

Knee joints ought to Nike Tn Blue 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. The steps of barefoot will be much larger compared with that when people put on shoes, and this has been released and found by a magazine called the "Foot and Ankle Research". When foot touches down the ground, the force on heels will be greater. A study has be finished by Daniel E Li Boman who was a professor of Harvard University Human Evolutionary Biology. Nike Tn Pink

Through the contrast between city primary and middle school students that used to put on shoes and students of countryside who used to be with barefoot, it was found that city students' foot touchdown point will be focused on heels with the touchdown ground while running. But countryside students' foot touchdown point mainly would focus on the front of feet. They would land on the ground lighter, and no obvious force would be produced. 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.

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. It was thought by scientists that human beings are designed for barefoot running. But the method is extremely critical, if there are slightly improper actions, and then there will be natural increase on stress fractures, muscle or tendon injuries and other dangers. 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.

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. The correct running posture Nike Tn White is to raise head and keep the back straight and relaxed. When feet touch down the ground, knee joints should be bend slightly. Arms should bend at about ninety degrees, and let arms extend as large as possible. In addition, suitable running programs should be chosen. For example, run five kilometers with ten to twelve weeks at the beginning, run ten kilometers with six to eleven weeks in intermediate progress, and run ten kilometers with eleven weeks at last. Even if the weather in early autumn is the most changeful, it is the best season to show fresh charms.
