目的:运用主观测试量表评价羽毛球运动鞋的舒适度。方法:以上海体育学院16名羽毛球运动员为测试对象,使用美国某公司运动科学研究室提供的感知测试量表进行了试穿实验,测试了两款不同品牌羽毛球专用鞋的鞋尖内部高度、鞋尖内部宽度、脚最宽处周长、脚腰/脚背、脚后跟和长等不同部位的穿着舒适度以及足底黏附性、前足柔韧性、脚后跟缓冲、脚后跟响应、脚后跟稳定性、后跟-脚趾过渡、前脚缓冲和整体感觉等不同性能指标。结果:从总体舒适度量表(General Fit Ballot)的各指标来看,除了鞋长度指标外,A鞋的其余各指标都存在一定的问题;从鞋性能动态测试量表(Dynamic Ballot)中喜爱程度(Liking)各指标来看,鞋A在脚后跟缓冲、后跟-脚趾过渡、前脚缓冲、足底黏附性、前足柔韧性等方面依然有很多不足,有待继续改进;对于鞋性能动态测试量表(Dynamic Ballot)指标强度(Intensity)而言,A鞋的足底黏附性(Underfoot Traction)和前足柔韧性(Forefoot Flexibility)明显不足、前足柔韧性和脚后跟稳定性明显有缺憾。结论:该量表适宜评价运动鞋的舒适度和相关运动性能,是运动鞋设计... 相似文献

基于足底压力的羽毛球运动足部受力特征研究 总被引：1，自引：0，他引：1
分析羽毛球常用步法的足底压力特征,为减少羽毛球运动中下肢损伤(特别是足部损伤)提供建议,并希望成为羽毛球鞋具设计的依据。利用足底压力测试系统对高水平羽毛球运动员左前场蹬跨步、右前场蹬跨步、一步蹬转起跳等常用步法动作进行测试。结果发现3种步法在离地阶段,足前区的内侧跖骨区以及大拇趾和第1、2跖骨区的最大压力均高于其他部位(P<0.05);着地阶段,蹬跨步是把足底压力集中于脚后跟和足外侧进行缓冲制动,蹬转起跳步则把压力集中于大拇趾以及第1、2跖骨区(P<0.05)。由此可见,羽毛球运动员应注意在采用不同步法时,足前区和足跟区中部及足外侧的负荷变化,并尽可能地选择穿着能够分散上述区域压力的专项鞋来避免足部受力的过度集中。 相似文献

运用摄影测量法和Novel Pedar-X足底压力测试系统采集了16名太极拳练习者在太极拳运动和正常步行中足底压力和运动影像信息,并对两种运动方式的单脚支撑姿势持续时间指标进行对比分析。研究表明:与正常步行相比,在太极拳运动中单脚支撑姿势总的持续时间所占比例(标准化值)较少(P<0.05);单次单脚支撑姿势平均持续时间较长(P<0.01);认为太极拳运动可以提高人体单脚平衡能力。另外还发现太极拳运动和正常步行中地面反作用力都在不断变化;太极拳运动中地面反作用力小于其正常步行值。 相似文献

为了解运动中运动鞋内的温度和湿度舒适性,采用6通道温、湿度测量系统对25名运动员穿3款运动鞋跑步时的鞋内脚前掌、足弓和足跟等3部位的温、湿度进行实时测量,并结合受试者主观问卷调查。结果发现:运动鞋内温度随运动时间增长呈上升趋势,跑步速度越快,前掌温度越高;运动鞋内相对湿度随运动时间增长呈下降趋势。运动结束后,足弓部的温度迅速升高,鞋内各部位湿度快速增长;穿不同运动鞋运动时鞋内温度和湿度变化有明显差异性,穿透气性和排湿性好的运动鞋运动时鞋内相对湿度可明显降低,穿透气性能较差的鞋则相对湿度不降反升,感觉不舒适。 相似文献

The purpose of this study was to determine whether there are differences in the perceived comfort, plantar pressure, and rearfoot motion between laced running shoes and elastic-covered running shoes. Fifteen male amateur runners participated in the study. Each participant was assigned laced running shoes and elastic-covered running shoes for use during the study. The perceived comfort, plantar loading, and rearfoot motion control of each type of shoes during running were recorded. When the laced running shoes and elastic-covered running shoes were compared, the elastic-covered running shoes were given a lower perceived comfort rating in terms of shoe length, width, heel cup fitting, and forefoot cushioning. The elastic-covered running shoes also recorded higher peak plantar pressure in the lateral side of the forefoot, as well as larger maximum rearfoot pronation. Overall, shoelaces can help runners obtain better foot-shoe fit. They increase the perceived comfort, and decrease the maximum pronation and plantar pressure. Moreover, shoelaces may help prevent injury in running by allowing better control of the aforementioned factors. 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

Comfort has been shown to be the most desired football boot feature by players. Previous studies have shown discomfort to be related to increased plantar pressures for running shoes which, in some foot regions, has been suggested to be a causative factor in overuse injuries. This study examined the correlation between subjective comfort data and objective plantar pressure for football boots during football-specific drills. Eight male university football players were tested. Plantar pressure data were collected during four football-specific movements for each of three different football boots. The global and local peak pressures based on a nine-sectioned foot map were compared to subjective comfort measures recorded using a visual analogue scale for global discomfort and a discomfort foot map for local discomfort. A weak (rs = ?0.126) yet significant (P < 0.05) correlation was shown between the peak plantar pressure experienced and the visual analogue scale rated comfort. The model only significantly predicted (P > 0.001) the outcome for two (medial and lateral forefoot) of the nine foot regions. Subjective comfort data is therefore not a reliable measure of increased plantar pressures for any foot region. The use of plantar pressure measures is therefore needed to optimise injury prevention when designing studded footwear. 相似文献

脑力、体力劳动者足底压力参数分布特征及评定 总被引：3，自引：0，他引：3
通过分析脑力、体力劳动者自然行走过程中峰力值（maxforce，MF）、达峰力值时间（time to max force）、冲量（impulse）等参数特征，探讨职业对足底压力分布的影响。采用比利时Footscan USB2平板式足底压测试系统对50名普通健康脑力劳动者和63名普通健康体力劳动者进行自然行走过程中动态足底压力测试。结果显示：脑力、体力劳动者左脚Toel、Toe2-5、Heel Lateral区域平均峰值（MF）存在显著性差异，右脚Mid foot、Meta5区域MF差异存在非常显著性（P〈0．01），左、右双足平均峰力值（MF）最大值均出现在足跟内侧（Heel Medial）。脑力、体力劳动者足底各区域达峰力值的时间（TMF），左右双足差异均存在非常显著性（P〈0．01）。脑力劳动者与体力劳动者行走过程中左足在Toel、Toe2-5、Meta1、Heel Medial、Heel Lateral区域的冲量（Impulse，IP），体力劳动者明显大于脑力劳动者且具有显著性差异〈0．01），体力劳动者与脑力劳动者的足底MF与足弓接触面积及足角度存在不同程度的相关。结果说明：脑力劳动者与体力劳动者行走过程中左右双足的平均峰力值、接触面积、冲量等参数都存在不同程度的差异，可能与长期从事的职业不同有关，建议经常进行体育锻炼或定制矫形鞋垫，可以缓解足底压力高压区的过度集中，不断维护足健康水平。 相似文献

We have performed a study on the thermo-formation process of plastic shells of boots for winter sports. The aim of the work has been to determine how the process parameters can improve the ergonomic and thermal comfort for athletes and winter sports participants. We have found that the initial deformation and memory effect are strongly influenced by the type of thermoplastic material used, heating time and cooling procedure. We have also found that the ovens currently used for this process are not correctly designed to obtain an efficient heat transfer and, therefore, a heating time of at least 12 min is necessary to achieve an average deformation of more than 2 mm. The measure of the boot flexural stiffness has shown that there are no changes in the load–deflection behavior after the thermo-formation process of a ski boot made of thermoplastic polyurethane. We have also found that the thermo-formation process decreases the pressure on skier’s feet of more than five times and, therefore, improves the comfort of the skier. 相似文献

The aim of this study was to investigate, for typical shoes and surfaces used in tennis, the relative role of the shoe and
surface in providing cushioning during running. Five test surfaces ranging from concrete to artificial turf were selected,
together with two shoe models. Impact absorbing ability was assessed mechanically using drop test procedures and biomechanically
using peak magnitude and rate of loading of impact force and peak in-shoe pressure data at the lateral heel. Differences in
biomechanical variables between shoe-surface combinations were identified using a two-way ANOVA (p < 0.05). Mechanical test results were found to rank the surfaces in the same order regardless of the shoe model, suggesting
that the surface is influential in providing cushioning. However, for all mechanical and biomechanical (p < 0.05) variables representing impact absorbing ability, it was found that the difference between shoes was markedly greater
than the differences between surfaces. The peak heel pressure data were found to rank the surfaces in the same order as the
mechanical tests, while impact force data were not as sensitive to the changes in surface. Correlations between mechanical
and biomechanical impact absorption highlighted the importance of testing the shoe-surface combination in mechanical tests,
rather than the surface alone. In conclusion, mechanical testing of the shoe-surface combination was found to provide a strong
predictor of the impact absorbing ability during running if pressure data were used. In addition, for typical shoe-surface
combinations in tennis, the shoe was found to have more potential than the surface to influence impact loading during running.
Finally, in-shoe pressure data were found to be more sensitive than force plate data to changes in material cushioning. 相似文献
