Analysis of Article Regarding Foot Strike Patterns in Running

In the present era of our culture, the pressure to become healthier and healthier, like health and our early ancestors, brought all new speculation. From "ancient dietary" cavemen to fashionable barefoot style running shoes, it seems people are now trying to reflect early Homo sapiens more than ever. As media and advertisements make our culture more natural, as Kevin Hatala, Mr. Heather Dingwall, Roshna Wundelich, Mr. Brian Richmond discovered, so beneficial to avoid injuries of long distance runners There is new evidence to suggest that it is not.

When most of us run barefoot or "run barefoot" sneakers, we automatically start running on your forefoot. This forefront strike is a natural walk for most people, but children can wear shoes and children who do not wear shoes are found by this survey, so you can not learn from wearing shoes. The cause of running injuries is currently under investigation, but research finds that falling to the instep of the feet potentially creates the high frequency power that causes the injured body to move up and through the bone did. If you fall in front of your feet, low frequency forces will rise to the muscles and the strike may spread. Running on your heel when you are barefoot is actually very embarrassing.

Many studies highlight the differences in the running pattern of the feet and compare the barefoot running shoes and habitual wearers of running shoes. Running barefoot results in a flattened foot landing and a reduced vertical ground reaction compared to running with shoes. The purpose of this study was to investigate the parameters that may affect the running pattern, the thickness of the midsole. Fifteen participants ran barefoot on the ground at a speed of 3.3 feet (-1) and the midsole thickness (0 mm, 2 mm, 4 mm, 8 mm, 16 mm) was different between the back leg and the forefoot I put on five shoes. There is no step. The impact strength was evaluated by using the transient peak of the vertical floor reaction force, the load velocity, the maximum acceleration of the tibia, and the velocity. Hip joint angle, knee angle and flexion angle were calculated at the time of contact and during stance period (range of motion and maximum). Not only the overall leg stiffness but also the external mesh joint moment and stiffness of the hip, knee and ankle joints were also observed.

Cushioned shoes exhibit loading rates similar to those of minimalist shoes during foot impact by individual impact. However, despite counterintuitive intuition, thick sole actually makes it possible to apply normal force to the foot. It all comes down to the way we walked on the ground while running. People who usually wear shoes and people wearing simple shoes usually form the front foot strike (FFS) mode; that is, when you land, the feet will first reach the ground . As the ankle moves, the calves and the arch and the Achilles tendon will stretch and the heel will be late. As a result, the landing becomes light and the force applied to the foot decreases. Shoes with a very thick sole make it possible for runners to perform rear foot strokes (RFS) on the heels without pain. During RFS, the resulting impact peak is still 7 times higher than FFS mode, since peak vertical impact force can not be converted from curved crotch to rotational energy.
