In most cases, running injuries are caused by repeated shocks when the foot touches the ground. The impact will penetrate the leg, which in the long run can cause some inflammation, the disease of the plantar fasciitis, and the risk of a slight fracture of the tibia. Oregon State University organized the world's first study on the impact of air-cushioned shoes on the legs and feet. Participants first wear regular running shoes for testing. After a recovery period of 7 to 10 days, repeat the same test with air cushion shoes. The results show that when the participants wear the air cushion shoes, the impact force of each step is increased.
Professor Kristin Pollard of Oregon State University said: "We have thought that high-buffer shoes can reduce the impact of injury, but these impacts are not reduced, bringing more bones, muscles and joints. Pressure. This means that wearing air-cushioned shoes increases the risk of running injuries.†Through slow-motion playback, the researchers found that barefoot runners are different from the shoes in their shoes, the former with the midfoot and the ground, while the latter The heel is first landed. The researchers pointed out that when the heel hits the ground, it is like hitting the leg with a hammer, and the force can reach three times the weight of the body. From this point of view, barefoot running reduces the risk of leg and foot injury. The so-called "barefoot is not afraid of wearing shoes, wearing ordinary shoes is not afraid to wear air cushion shoes."
