Commonly used simple methods: 1, often consciously walk along a straight line; pay attention to walk, run when the tip of the foot does not deviate outward. 2.Usually use the inside of the foot to kick the shuttlecock, alternating between the feet. 3.Frequently jump forward and backward with both feet together. In daily life, we often see some people with their feet outward, or inward, which is often referred to as “eight feet”. The main reason for the “eight feet” is the premature standing and learning to walk at an early age, the strength of the legs is weak, it is difficult to maintain body balance, the toes are naturally separated to the left and right to expand the area of the sole of the foot to increase stability and prevent falls, slowly forming habits. In addition, some people walk with incorrect posture, slowly forming the habit of becoming a deformity of the eight feet. Systematic self-correction training methods are: 1, squatting method inside the eight-footed people, two feet externally rotated position standing; outside the eight-footed people, two feet internally rotated position standing, do squatting up action, repeat 80 ~ 100 times, a total of four sets of exercises. 2, longitudinal jumping method abduction leg jump can be corrected in the eight feet, the leg jump can be corrected outside the eight feet. Shuttlecock is also a help to correct the “eight feet” better exercise program. If it is “outward eight-footed”, kick the shuttlecock more internal abduction kick, that is, bending the knee with the inside of the foot kick, if the “inside eight-footed”, can do more external abduction kick (that is, bending the knee inside buckle, with the outside of the foot kick). Repeat 80 to 100 times for each foot, a total of 4 sets of exercises. 3, shelve the leg method a leg on the horizontal surface, first pull loose lower limb joint ligaments, about 10 minutes and then use both hands to trigger the foot, the eight-footed people to the outside trigger, the eight-footed people to the inside board, each time 10 minutes. Repeat 4 times for each left and right foot. 4, straight line stepping method Draw two straight lines on the ground, the distance between the two straight lines become a horizontal fist, requiring the heel and toe to step on the straight line, the pace from small to large, from slow to fast, 30 to 50 round trips each time, a total of four exercises. 5, straight line jumping method on the ground to pull a rope, so that the palms of the feet parallel to the rope run, but also along the drawn straight line, requiring each step to step on the line, their knees and toes are facing the front, do not deviate. Run 50 to 100 meters, a total of 4 times to practice. Note: When doing various postures, pay attention to the direction of the toe taut, if it is the “inner eight feet” should pay attention to the outward taut toe; is the “outer eight feet” should try to inward taut toe. Keep the knee and ankle joints straight, especially in doing leg lifts, squatting, jumping and other movements within the buckle, toes should be consciously aligned with the direction of advance, along a straight line. The use of the above correction methods at the same time, usually pay attention to the development of correct sitting, standing, walking, running posture, as long as the thought of attention, persistent, will be able to achieve the purpose of correction.
