静立平衡COP晃动参数能有效反应老年人姿势控制能力,但老年人跌倒风险的敏感预测指标并不确定,存在争议。本研究通过对34名65岁以上老年女性的跌倒史和跌倒风险指数与其静立平衡COP晃动速度和距离的关系进行统计分析。研究认为:对于65岁以上的老年女性,静立平衡测试中,COP在单脚站立的左右晃动(速度和位移)和Tandem步站立的前后晃动(速度和位移)能有效评价老年女性的平衡能力、预测跌倒风险;一定难度站立姿势的静立平衡测试更有利于评价普通健康老年女性的平衡能力、预测跌倒。 相似文献

目的通过比较双足、单足睁眼与闭眼站立时平衡性的差异,探讨穿普通鞋、负跟鞋、光脚时静态平衡的特征。方法采用Zebris平板式足底压力测试系统对普通人进行穿着不同鞋(光脚、普通鞋、负跟鞋)静态平衡能力的测量,得出包络宽度、包络长度、包络角度、包络面积等九项平衡参数。结果双足睁眼站立时,包络宽度、压力中心全长、压力中心垂直摆动、左脚压力百分比(后)、右脚压力百分比(后),右脚压力百分比(全部),均p<0.05存在组间差异;单右足闭眼站立时,包络长度、包络面积、压力中心垂直摆动上,均p<0.05存在组间差异;双足闭眼与单右足睁眼站立时,3种鞋型之间不存在组间差异(p>0.05)。结论不同鞋型会对人体的静态平衡稳定性产生一定的影响。 相似文献

为探讨反向走改善或提高机体平衡能力的价值，本研究以26名61～70岁的老年女性为研究对象，随机分为2组，一组进行常规健身锻炼（正向快走或慢跑），一组进行反向走锻炼。2组老年人在锻炼开始前和锻炼12周后，检测平衡功能（闲眼单脚站立时间、Footscan测力台系统静态睁眼双足站立测试和身体最大活动幅度测试、步态分析）。研究结果发现：12周锻炼后，反向走组老年人的闭眼单脚站立时间明显延长，身体最大活动幅度测试中X轴方向运动的最大和最小幅度明显增加，步态分析中右足跟到达最大压力的时间明显增加、身体重心额状轴最大位移明显降低。而常规健身组老年人只是在身体最大活动幅度测试中X轴方向运动的最小幅度明显增加。上述结果说明：反向走与正向快走或慢跑相比，可显著改善老年人的平衡功能，因此可以作为老年人平衡能力锻炼的一种新方式。 相似文献

The aim of the study was to evaluate the effect of maximal specific physical effort on postural balance and rifle stability in biathletes in a standing shooting position. The study included 10 junior elite biathletes. The measurements were taken with the Vicon system and AMTI force platform. Postural balance and rifle stability characteristics were determined at rest as well as 1 and 5 min post maximal specific physical effort which was performed on a ski ergometer and continued until exhaustion. Maximal physical effort exerted a significant effect on all examined postural sway and rifle sway characteristics. The duration of the post-exercise changes was longer than 5 minutes. Higher post-effort rifle sway was observed in the vertical direction than in the across the shooting line direction. Post-effort postural balance impairment in the shooting line was much greater than in the across the shooting line direction. Moreover, a strong correlation was found between postural balance and rifle stability. Maximal physical effort influenced postural balance and rifle stability during aiming. Rifle sway during aiming in a standing shooting position seems to be coordinated with the postural sway of the biathlete’s body. Thus, an increase in postural sway contributes to greater sway and lesser stability of the rifle. 相似文献

The frequency of one-legged stance and two-legged stance differs considerably among sports. We therefore expect the balance ability of athletes from different sports to vary. This study compared the sway characteristics during a static one-legged stance of soccer players, basketball players, swimmers, and non-athletes. The centre of pressure sway during one-legged stance of ten male participants representing each of the four groups was measured using a stabilometer. Centre of pressure sway was assessed by four sway factors: sway velocity, anterior-posterior sway, horizontal sway, and high-frequency sway. None of the four groups of participants showed significant differences in body sway between standing on the dominant leg and standing on the non-dominant leg. The soccer players had more high-frequency sway and less anterior-posterior sway and horizontal sway than the basketball players, swimmers, and non-athletes. These results suggest that soccer players have superior ability to maintain a stable one-legged stance. Further study is required to determine how much of the superior balance ability in soccer players is innate and how much is developed through training, as well as to determine the relationship between balance ability and playing performance. 相似文献

目的:对我国自由式滑雪空中技巧队运动员姿势控制能力进行训练和评价,为后期的专项训练实践提供指导和参考。方法:对13名国家运动员(男性6名,女性7名)进行3种不同的姿势控制能力训练,利用METITUR平衡能力测试系统在训练前后对13名国家运动员进行平衡能力测试,一个训练周期后,对2017年和2018年两个赛季运动员的技术动作进行对比分析。结果:通过METITUR平衡能力测试,13名运动员静态平衡能力在前后方向上(Y轴向)的稳定性升高,说明运动员在控制重心能力上有所提高。通过训练前后运动员的动态平衡能力测试人体重心曲线图,运动员训练后在支撑面左右方向的自动态平衡能力有所有提高。技术动作对比分析的结果显示,运动员的着陆成功率也有了较大幅度的提高。结论:通过为期6个月的姿势控制能力的训练,运动员的静态平衡能力在支撑面前后方向上明显提高,动态平衡能力在支撑面后的左右方向上有显著提升。 相似文献

AbstractValid and reliable accessible measures of balance are required in a health-related fitness test battery, both in the general population and in groups with special needs. For this purpose, the capability of the Wii Balance Board (WBB) in evaluating standing balance was analysed and compared with a laboratory-graded force platform (FP). A 30-s double limb standing test with open and closed eyes was performed by 28 individuals (12 male and 16 female, mean age = 23.8, SD = ±2.7 years). A simple method of acquisition of the centre of pressure (CoP) over time was applied to compare WBB and FP simultaneously on the same signal. User-defined software was developed to obtain the CoP from WBB over time and the resulting related measures and graphical representations. The comparison of measures, such as sway path and maximum oscillations along the anterior–posterior and medial–lateral direction, obtained with the FP and the WBB shows that the latter, in conjunction with the user-defined developed software, can be appropriate, considering prescribed limits, and an easy-to-use tool for evaluating standing balance. 相似文献
