如果把鞋的历史进行分类,可以说基德是“NIKE”鞋初期类型的代表人物。 90年代初,NIKE提高了在美国国内篮球鞋业的市场占有率。那个时候10几岁的基德实力已经被NIKE所认同,并从中受到了很多的恩惠。从进入NBA开始,就和NIKE签定了合同,并一心一意地服役至今。 80年代,还是CONVERSE、ADIDAS的时代,但NIKE通过迈克尔·乔丹创造了发展的机会。那时对于刚进NBA的迈克尔·乔丹来说,真正得到NIKE的恩惠还是在90年代初。而NIKE在篮球领域真正着手于人才、资金等战略也是在90年代初。 相似文献

在洛杉矶湖人对洛杉矶快艇的比赛中,科比没有穿着自己的新款球鞋——Zoom Kobe3,而是穿上了刚刚推出的另一款新球鞋。这也告诉人们。在即将到来的北京奥运会上,科比将不会穿着自己签名款式的Zoom Kobe系列了,而能让Kobe放弃自己签名鞋的原因就是一款更强大的鞋——NIKE HYPERDUNK。HYPERDUNK最大的特点就是一轻。HYPERDUNK篮球鞋的重量仅仅为13盎司,比普通耐克篮球鞋要轻18%。要知道科比在每场比赛中平均要跑2.5英里,重量更轻的篮球鞋意味着他能在球场上获得更多的能量。在Nike订货会的时候,这款鞋被放在天平的一端,天平的另一端则是羽毛,鞋子是不可能比羽毛轻的,但是Nike想告诉我们的只有一个:鞋子很轻。而实现这一目标的核心则是被NIKE称之为"Flywire"的鞋面支撑技术。这一技术最早是应用在田径跑钉鞋上的,其原理与悬索大桥的钢缆相同。侧面用一根根强韧的细尼龙丝"吊"住,材料只应用于结构中所必需的部位。以超强韧的尼龙细丝代替传统鞋面材料为足部提供精准的支撑,从而使运动鞋的重量大幅减轻。"Nike Hyperdunk是超轻质的篮球鞋,它牢固而且响应迅速,能为我在比赛中带来真正的优势。"科比说道。 相似文献

Klap冰刀铰链点定位和冰鞋跖屈对能量输出影响的研究 总被引：1，自引：0，他引：1
利用纵跳模型模仿Klap冰刀的蹬冰推离阶段,以此评估铰链点位置和鞋底跖屈对能量产生的影响.通过在跑鞋下绑附不同长度的木板和一个在跖骨头下跖屈木板,选择6名速滑运动员进行一组3次的最大强度纵跳,一共5组,每组穿着条件分别如下:跑鞋、在跖骨头下跖屈木板、(距离足尖)-25 mm木板、0 mm木板和+25 mm木板.在后3个刚性鞋底条件下,产生的总能量没有显著差异,但是存在势能和动能方面的差异.在产生的总能量和动能方面,跖屈鞋底比刚性鞋底大9%.如果纵跳的能量测量上的差异反映了滑行结果,跖屈鞋底可能比当前的Klap冰刀(该鞋底是刚性的)提高3%的滑行速度. 相似文献

游泳运动对大鼠股骨和腰椎骨生物力学特性影响的研究 总被引：1，自引：1，他引：0
实验目的:探讨游泳训练对大鼠股骨和腰椎骨生物力学特性的影响。实验方法:以36只SD大鼠为实验对象,以大鼠游泳训练为运动模型,分为对照组(n=18)和实验组(n=18),每天训练30min,共6周。取双侧股骨第5腰椎制成试件,在日产万能试验机和力学参数测试系统中做3点弯曲的生物力学特性测试(弹性模量、最大载荷、屈服应力、最大应力、能量吸收等)及对骨的横断面积和骨矿含量进行测定。实验结果:股骨3点弯曲数据显示两组间的弹性模量、最大载荷、屈服应力、屈服应变无明显变化(P>0.05),而最大应力、最大应变和能量吸收则有显著下降的趋势(P<0.05),横断面积和骨矿含量无明显变化(P>0.05)。腰椎骨压缩试验的结果显示,实验组除能量吸收外(P>0.05),其最大载荷、屈服应力、最大应力、屈服应变和骨矿含量等参数均有显著增加(P<0.05)。提示,游泳对腰椎的刺激较大,可使腰部生物力学特性产生适应性变化。根据国内、外的相关研究,游泳运动是防治腰部骨质疏松和下腰部疼痛较好的锻炼方法之一,值得在临床上进一步研究。 相似文献

运动鞋核心技术的生物力学研究 总被引：3，自引：2，他引：1
运动鞋科技的每一项进步,都离不开生物力学研究.无论国际一线品牌Nike和Adidas,还是以安踏为代表的国内一线品牌,其核心技术的创新都必须遵循人体运动的生物力学原理.足的结构与力学功能问题、"足一鞋一地"相互作用的力学问题、鞋体材料与结构的运动功效问题以及足的骨结构生物力学建模问题,一直以来都是运动鞋生物力学研究的主题.运动鞋的核心技术主要体现在材料和结构方面,材料决定了性能,结构决定了功能.但运动鞋的鞋底科技则代表着运动鞋的核心科技,国内、外品牌运动鞋的关键技术也多集中体现在鞋底科技上.国际一线品牌运动鞋的核心技术主要是缓震减震、能量回归、足跟控制和模拟裸足.国内一线品牌运动鞋虽然新概念频出,但技术原理雷同,运动鞋的生物力学实验研究和功能测试不足,主因则是运动鞋生物力学研究的专业人才十分匮乏. 相似文献

In this study, we evaluated the protective functions of cloth sport shoes, including cushioning and lateral stability. Twelve male students participated in the study (mean +/- s: age 12.7 +/- 0.4 years, mass 40.7 +/- 5.9kg, height 1.50 +/- 0.04m). Cloth sport shoes, running shoes, basketball shoes, crosstraining shoes, and barefoot conditions were investigated in random sequence. Human pendulum and cutting movement tests were used to assess cushioning performance and lateral stability, respectively. For cushioning, the running shoes (2.06 body weight, BW) performed the best, while the cross-training shoes (2.30 BW) and the basketball shoes (2.37 BW) both performed better than the cloth sport shoes (2.55 BW) and going barefoot (2.63 BW). For the lateral stability test, range of inversion--eversion was found to be from 3.6 to 4.9 degrees, which was far less than that for adult participants (> 20 degrees). No significant differences were found between conditions. All conditions showed prolonged durations from foot-strike to maximum inversion (66-95 ms), which was less vigorous than that for adult participants (< 40 ms) and was unlikely to evoke intrinsic stability failure. In conclusion, the cloth sport shoe showed inferior cushioning capability but the same lateral stability as the other sports shoes for children. 相似文献

ABSTRACT This study examined the effects of shoe collar-height and counter-stiffness on ground reaction force (GRF), ankle and knee mechanics in landing. Eighteen university basketball players performed drop landing when wearing shoes in different collar height (high vs. low) and counter-stiffness (stiffer vs. less stiff). Biomechanical variables were measured with force platform and motion capturing systems. Two-way repeated measures ANOVA was performed with α = 0.05. Wearing high collar shoes exhibited smaller peak ankle dorsiflexion and total sagittal RoM, peak knee extension moment, but larger peak knee varus moment than the low collar shoes. Stiffer counter-stiffness shoes related to smaller ankle inversion at touchdown and total coronal RoM, but larger peak knee flexion and increased total ankle and knee sagittal RoM than the less stiff counter-stiffness. Furthermore, wearing stiffer counter-stiffness shoes increased forefoot GRF peak at high collar condition, while no significant differences between counter-stiffness at low collar condition. These results suggest that although higher collar height and/or stiffness heel counter used can reduce ankle motion in coronal plane, it would increase the motion and loading at knee joint, which is susceptible to knee injuries. These findings could be insightful for training and footwear development in basketball. 相似文献

ABSTRACTThis study examined the effect of wearing time on comfort perception and landing biomechanics of basketball shoes with different midsole hardness. Fifteen basketball players performed drop landing and layup first step while wearing shoes of different wearing time (new, 2-, 4-, 6- and 8-week) and hardness (soft, medium and hard). Two-way ANOVA with repeated measures was performed on GRF, ankle kinematic and comfort perception variables. Increased wearing time was associated with poorer force attenuation and comfort perception during landing activities (p < 0.05). The new shoes had significantly smaller forefoot (2- and 4-week) and rearfoot peak GRF impacts (all time conditions) in drop landing and smaller rearfoot peak GRF impact (6- and 8-week) in layup; shoes with 4-week of wearing time had significantly better perceptions of forefoot cushioning, forefoot stability, rearfoot cushioning, rearfoot stability and overall comfort than the new shoes (p < 0.05). Compared with hard shoes, the soft shoes had better rearfoot cushioning but poorer forefoot cushioning (p < 0.05). Shoe hardness and wearing time would play an influential role in GRF and comfort perception, but not in ankle kinematics. Although shoe cushioning performance would decrease even after a short wearing period, the best comfort perception was found at 4-week wearing time. 相似文献

This study investigated the effects of body mass and shoe midsole hardness on kinetic and perceptual variables during the performance of three basketball movements: (1) the first and landing steps of layup, (2) shot-blocking landing and (3) drop landing. Thirty male basketball players, assigned into “heavy” (n = 15, mass 82.7 ± 4.3 kg) or “light” (n = 15, mass 63.1 ± 2.8 kg) groups, performed five trials of each movement in three identical shoes of varying midsole hardness (soft, medium, hard). Vertical ground reaction force (VGRF) during landing was sampled using multiple wooden-top force plates. Perceptual responses on five variables (forefoot cushioning, rearfoot cushioning, forefoot stability, rearfoot stability and overall comfort) were rated after each movement condition using a 150-mm Visual Analogue Scale (VAS). A mixed factorial analysis of variance (ANOVA) (Body Mass × Shoe) was applied to all kinetic and perceptual variables. During the first step of the layup, the loading rate associated with rearfoot contact was 40.7% higher in the “heavy” than “light” groups (P = .014) and 12.4% higher in hard compared with soft shoes (P = .011). Forefoot peak VGRF in a soft shoe was higher (P = .011) than in a hard shoe during shot-block landing. Both “heavy” and “light” groups preferred softer to harder shoes. Overall, body mass had little effect on kinetic or perceptual variables. 相似文献
