Research results that running shoes weaken legs and increase injury

`` Wearing running shoes when running '' is a common sense, and in recent years running shoes that have increased the running speed due to the powerful support performance of the cushion have appeared and even overwhelmed the

land world . .. However, Peter Francis of Leeds Beckett University, who is an expert in the prevention and treatment of injuries related to running, explains the research results that such running shoes cause rather injury .

Running shoes may cause injuries – but is going barefoot the fix?

Archaeological evidence reveals that primitive shoes appeared about 30,000 years ago, and that mankind has been wearing them for a long time. A study published more than 100 years ago concluded that 'there is no difference in the shape of the foot between those who wear shoes and those who do not', Francis said, 'Since the 1970s, The situation has changed with the advent of cushioned running shoes. '

According to Francis, in recent years, research results that 'running shoes have an adverse effect on the body' have been reported one after another. Research team of Harvard University in 2017, 'the modern running shoes is to increase the injury' a paper that announcement , and also of Francis himself team running shoes embarked on research on the impact on the body.

According to an experiment conducted by Mr. Francis, subjects aged 12 to 19 years old in New Zealand who have a habit of bare-foot running were less likely to feel pain in their knees, ankles, and feet than children of the same age group in other countries. thing. In addition, a study published in 2018 showed the findings that 'wearing shoes reduces muscles and strength in the legs.'

According to a 2019

survey by Francis, 35 to 50% of sprinters and marathon runners always found somewhere injured. The most common injuries were knees, shins, ankles, and feet. All of these points are the bones where the force is directly transmitted from the muscles and the joints of the bones.

According to Francis, it is 'nervous' that causes such injuries. According to the latest research results , when the foot touches the ground, the information obtained by the skin, ligaments, and tendons is transmitted to the brain and spine, but the accuracy of the information decreases when wearing shoes. Turned out. In one example, Francis explained that wearing shoes reduces the control of the muscles that must be moved to absorb shock.

Francis pointed out that the excessive braking force provided by running shoes increases the probability of plantar aponeuritis, which often affects marathon runners. He also mentioned the possibility of long-term use of shoes weakening the foot and eliminating the arch.

However, running barefoot is not the only benefit. Francis points out that he is more likely to get injured in the calf and Achilles tendon, especially if he's not used to barefoot. He explained that the reason for this is that his stride becomes shorter when he barefoot, and his power is concentrated on the tip of his toes.

Symptoms of continuous wearing of running shoes may be improved by running or walking barefoot. However, since it is actually difficult to run barefoot, the cushioning property is low and the muscle strength and strength of the foot of the subject who used barefoot shoes for 8 weeks, which gives a feeling similar to running barefoot, has recovered. Francis cites the results of the experiment and recommends barefoot shoes.
