【摘要】：如今高跟鞋作為大多數(shù)女性的選擇,逐漸成為了女性生活中不可缺少的部分,同時(shí)它也是影響女性身體健康的重要因素之一。本文研究首次同時(shí)運(yùn)用三維錄像解析系統(tǒng)、肌電測(cè)試系統(tǒng)及三維測(cè)力臺(tái)系統(tǒng)對(duì)女性穿7cm高跟鞋和平底鞋行走進(jìn)行同步測(cè)試,并得出以下結(jié)果:(1)運(yùn)動(dòng)學(xué)分析顯示,足跟著地時(shí)刻,足全腳掌著地時(shí)刻以及足跟離地時(shí)刻,穿7cm高跟鞋會(huì)導(dǎo)致髖關(guān)節(jié)角和膝關(guān)節(jié)角減小,踝關(guān)節(jié)角增大。足趾離地時(shí)刻,穿7cm高跟鞋此時(shí)髖關(guān)節(jié)角有所減小,而膝關(guān)節(jié)角和踝關(guān)節(jié)角有所增加。支撐初期,穿7cm高跟鞋步速較慢,所用時(shí)間為0.13秒。穿7cm高跟鞋髖關(guān)節(jié)角增加,膝關(guān)節(jié)角和踝關(guān)節(jié)角都有減小。支撐中期,穿7cm高跟鞋步速明顯較慢,所用時(shí)間是整個(gè)支撐階段最多的為0.44秒,主要由膝關(guān)節(jié)過分屈曲造成。穿7cm高跟鞋踝關(guān)節(jié)角和髖關(guān)節(jié)角都減小,但膝關(guān)節(jié)角卻有增加。支撐后期,穿7cm高跟鞋步速較慢,所用時(shí)間為0.14秒。穿7cm高跟鞋膝關(guān)節(jié)角減小,踝關(guān)節(jié)角和髖關(guān)節(jié)角整體都增加。(2)肌電分析顯示,支撐初期和支撐中期穿7cm高跟鞋左腳的脛骨前肌、腓腸肌外側(cè)肌的平均積分肌電值分別為:39.75 u Vs、37.85u Vs和56.33u Vs、52.67u Vs。支撐初期和支撐中期這兩塊肌肉肌電活動(dòng)都較強(qiáng),特別是支撐中期肌電活動(dòng)非常激烈,平均積分肌電值是整個(gè)支撐階段中最大的,同時(shí)脛骨前肌、腓腸肌外側(cè)肌平均肌肉振幅百分比也大于穿平底鞋,因此,這兩個(gè)階段容易造成小腿肌肉疲勞,導(dǎo)致小腿酸痛。支撐后期,穿7cm高跟鞋左腳的脛骨前肌和腓腸肌外側(cè)平均積分機(jī)電值小于穿平底鞋,原因是穿7cm高跟鞋行走時(shí),在支撐后期,踝關(guān)節(jié)始終處于屈的狀態(tài)對(duì)腓腸肌的預(yù)拉長減小,導(dǎo)致肌腱力臂減短,減小了蹬伸階段的能力。(3)動(dòng)力學(xué)分析顯示,穿7cm高跟鞋垂直方向力在足跟完全著時(shí)刻前出現(xiàn)兩次波動(dòng),說明在足跟剛接觸地面到足跟完全著時(shí)刻,穿7cm高跟鞋在垂直方向不穩(wěn)定。穿7cm高跟鞋在足跟著地時(shí)刻、足全腳掌著地時(shí)刻和足趾離地時(shí)刻,X方向和Y方向上晃動(dòng)較大。在Z方向上,在足跟著地時(shí)刻,出現(xiàn)了一極大值為6806.18N,此刻力值是最大的。在足全腳掌著地時(shí)刻,在Z方向上,受力達(dá)到最小為4436.54N。在足趾離地時(shí)刻,出現(xiàn)了又一極大值為6390.82 N,但小于足跟著地時(shí)刻的力值。左腳足全腳掌時(shí)刻在X方向上和Y方向上晃動(dòng)是最小。而X方向上和Y方向上晃動(dòng)最大是在左腳足跟著地時(shí)刻左腳足趾離地時(shí)刻。
[Abstract]:Nowadays, as the choice of most women, high heels have gradually become an indispensable part of women's life, and it is also one of the important factors affecting the health of women. In this paper, for the first time, three dimensional video analysis system, myoelectric testing system and three dimensional dynamometer system are used to simultaneously test women walking in 7cm high heels and flat shoes, and the following results are obtained: (1) Kinematics analysis shows that: (1) Kinematics analysis shows that: 1. At the time of foot following, the moment of full foot landing and the moment of heel leaving the ground, wearing 7cm high heels will result in the decrease of hip joint angle and knee joint angle, and the increase of ankle joint angle. The angle of hip joint decreased, while the angle of knee joint and ankle joint increased. In the early stage of support, the walking speed of wearing 7cm high heels is slow, and the time is 0. 13 seconds. The angle of hip joint increased, the angle of knee joint and ankle joint decreased. In the middle stage of support, the walking speed of wearing 7cm high heels was obviously slower, and the time used was the maximum of 0.44 seconds in the whole support stage, which was mainly caused by the excessive flexion of the knee joint. The ankle angle and hip angle in 7cm heels decreased, but the knee joint angle increased. In the later stage of support, the speed of walking in 7cm heels is slow, and the time is 0. 14 seconds. The knee angle of wearing 7cm heels decreased, and the ankle angle and hip angle increased. (2) Electromyographic analysis showed that the anterior tibia muscle of the left foot of 7cm high heels was worn in the early and middle stages of support. The mean integral myoelectric values of the lateral gastrocnemius muscle were 39.75 u Vs,37.85u Vs and 56.33 u Vs,52.67u Vs., respectively. The myoelectric activity of the two muscles was strong in the early and middle stages of support, especially in the middle period of support. The mean integral myoelectric value was the largest in the whole support period, and the tibial anterior muscle was also the largest. The average muscle amplitude percentage of the lateral gastrocnemius muscle is also higher than that of wearing flat shoes. At the later stage of support, the average integral electromechanical value of the anterior tibial muscle and the gastrocnemius muscle in the left foot of the 7cm heels was lower than that in the flat shoe. The reason was that when walking with 7cm high heels, the ankle was always in the flexion state and the prestretching of the gastrocnemius muscle decreased during the later supporting period. As a result, the tendon arm is shortened and the ability to push and extend is reduced. (3) dynamic analysis shows that the vertical force in the 7cm stilettos fluctuates twice before the heel is fully on the heel, indicating that the heel has just touched the ground from the heel to the full heel landing. Wearing 7cm heels is not stable in the vertical direction. Wear 7cm heels in the heel of the foot, foot on the soles of the moment and the toe off the ground, X direction and Y direction shaking larger. In the Z direction, a maximum of 6806.18N appears at the foot following moment, and the force is the largest at this moment. When the foot is on the ground on the soles of the foot, in the Z direction, the minimum force is 4436.54N. Another maximum is 6390.82 N, but less than the force value at the foot following moment at the time when the toe is off the ground. The left foot's full soles are minimum in X and Y directions. The maximum sloshing in X and Y direction is at the moment when left foot follows the left toe.
