Word flip flop note Early years, "flip" is also only some cool, dragging the young boys, this cool, convenient flip flop, has been on the feet of many fashionable girls, and more richer style. However, experts warned: wearing a female dragons, carefully wear into the "eight characters." Auburn University researchers found that flat skull can hardly give any support to the foot, wearing it will gradually change a person walking way, stride, and ultimately the heel, soles of the feet, ankle serious problems. A doctor explained that wearing a flip flop when walking, because the only band between the toes can not give enough support to the feet to mention the flip flop, whenever the heel off the ground, the toes will bend up the "hook" with flip flop, Not the natural force of the situation. If the time is too long, will lead to the muscles in front of the leg feel sore, in order to avoid the embarrassment of falling shoes, but also shorten the pace, ankle to the inside turn, that is, we often say "within the character". When you wear the word drag and walk, the center of gravity will tilt forward, the knee will be slightly curved, the waist will bend back, over time, knee and waist spine will be pain. Like wearing the word drag the female will often occur heel pain, and even heel spur. Sun Wei pointed out that the culprit of this problem is the flip flops. Long wear high heels, excellent soles or soles are not flat, heel weight is too large, easily lead to plantar fascia inflammation, there heel pain. Disadvantages Although many people think that the flip flute, comfortable, some people wear more every day. But the character is not very durable, the word tape in the wearing after a period of time easy to break, some people can be converted to tape tape. However, the average life expectancy of the flip flop is usually no more than one year. In addition, some experts believe that wearing a flip flop to force the shoes to grasp the internal force, will cause pressure on the foot, so not suitable for long wear.
Word flip flop harm When the summer vacation ends, the students have to return to school when the leg pain, foot pain to the hospital hospital doctor's number greatly increased. This phenomenon has aroused the concern of Professor Wendi Weimer. She is Associate Professor of Biomechanics at Auburn University and Director of Biomechanics Laboratory. She found that the pain of the legs and students, most of the summer wear most shoes is the word drag. When the fall back to school to wear tennis shoes or street shoes, legs and feet had a strong discomfort. Under the auspices of Professor Wendi Weimer, students from the Department of Biomechanics have set up a research group for the fliplist. The group called 39 volunteers to do the experiment, these volunteers both men and women, aged between 19 and 25 years old. In the experiment, the volunteers will wear the running shoes and flip flop. In order to make the data as objective as possible, the experiment to provide the word from the different manufacturers and retailers, priced from $ 5 to $ 50 range. Similarly, running shoes is also a variety of different prices and design. Participate in the experiment volunteers, will be in the back, hip, calf, ankle, foot and other places affixed to the sensor. There is a platform on the ground, when the foot up, the foot and the platform surface contact moment, will record the foot of the vertical force of the data. At the same time, the experimenter's movement gestures, their hip, legs, ankles, feet, toes of any subtle movements are recorded by the video system. The experimental report pointed out that when people wear the word drag, people walking shorter pace. This leads to the body to bear more pressure, because the same distance you have to spend more steps. This means that the muscles and joints will be more wear and tear. Everything comes from the little movement of the toes when walking. When wearing a flip flop, people will worry that the shoes will fly off, so when walking subconsciously bent from the toe to pull the soles. "The body is a delicate and wonderful machine.When you exercise a group of muscles, will be involved in the movement of several groups of muscles to tighten the muscles of the toes, will cause those who pull the toe lift muscles to stop movement. When you walk, you can not lift your toes high enough. "This is a chain reaction. Because of the need to clamp the shoes, the toes can not relax and lift, which leads to greater changes in the ankle angle, the heel of the vertical force is smaller, so the same experimental person, when he wears the word drag, The time is smaller. "The change in stride will lead to a series of changes in the body's power chain, extending from the sole, extending to the ankle, calf, knee, hip, back, extending throughout the body," Shroyer said. Bend the toes to tighten the soles of this action will be excessive use of plantar fascia and from the toes to the heel of the connective tissue, resulting in the soles of the feet, heel inflammation so that the hip, back pain. "There are buckle sandals that are more healthy choices because your toes do not have to bend the tightening shoes to keep the shoes from flying off, and these shoes also provide better protection for ankles and heels," Shroyer said. Shroyer also has two pairs of characters, he said: "The experiment does not recommend people never wear a word drag, but can not wear them all day wandering, and running shoes, it should be three to four months to replace. Tendon, English is Achilles Tendon, Greek mythology of the Achilles heel. The Achilles tendon connects the ends of the peroneal muscle with the calcaneus. When we walk, the calf muscles shrink, Achilles tendon to help him pull the heel lift, from the ground. Wearing a word drag and walk, because the need for more power to lift the heel, which led to the needs of the Achilles tendon, it is prone to Achilles tendonitis.
