Insoles with supporting functions and application

Abstract

The invention discloses insoles with supporting functions for a race walking athlete and application. The insoles with the supporting functions comprise insole bodies; each insole body from up to bottom includes an insole metatarsal bone support part used for supporting a metatarsal bone, an insole foot arch support part used for supporting the foot arch part and an insole heel support part for supporting the heel. According to the insoles with the supporting functions, by designing protrusions with supporting effects, the force applied to the foot arch parts is increased, the pressure peak value and impulse of the metatarsal bones and heels are reduced, and risks of stress fractures of the two common overuse injury parts are reduced; the functional insoles can reduces a reactive force ofthe ground in the vertical direction when the metatarsal bone support parts and the heel support parts are in contact with the ground, so that the risks of overuse injuries of the feet and legs are reduced.

Description

technical field [0001] The invention relates to a functional insole used in race walking events, in particular to a supporting functional insole and its use. Background technique [0002] Race walking, especially the 5km and 10km events, has become more and more popular in recent years and is rapidly becoming a popular leisure fitness sport. The reason for this popular trend may be due to people's perception of race walking as a sport that can provide sufficient fitness effect and cause very little harm to the human body. However, researchers believe that race walking is a sport with a high injury rate. Francis et al. conducted a questionnaire survey of 682 race walking athletes and found that nearly 3 / 2 of the race walking athletes had one or more injuries in their careers. 90% of race walkers feel pain during the game, and the remaining 10% feel pain throughout the game. A study made statistics on 31 race walking athletes and found that blisters on the heel and metatars...

AI Technical Summary

Problems solved by technology

During the race walking process, the soles of the athletes have to step on the ground repeatedly for 1 to 4 hours. During this period of time, the metatarsal head and the heel are subject to high pressure and pressure, and overuse injuries are prone to occur.

Repeated treading action on the soles of the feet will lead to stress fractures of the metatarsal heads, especially the second and third metatarsal heads. The increased pressure on the heel when stepping on the ground during walking will cause the strain of the tibialis anterior muscle group. It may cause common lower extremity injuries in some parts. The peak value of the ground reaction force during race walking is greater than that of normal walking, which may easily cause sprains of the musculoskeletal structure in the middle of the tibia; when the musculoskeletal system is overloaded, overuse sexual injury occurs
