Relationship of proprioception,cutaneous sensitivity,and muscle strength with the balance control among older adults

BackgroundBalance impairment is one of the strongest risk factors for falls. Proprioception, cutaneous sensitivity, and muscle strength are 3 important contributors to balance control in older adults. The relationship that dynamic and static balance control has to proprioception, cutaneous sensitivity, and muscle strength is still unclear. This study was performed to investigate the relationship these contributors have to dynamic and static balance control.MethodsA total of 164 older adults (female = 89, left dominant = 15, age: 73.5 ± 7.8 years, height: 161.6 ± 7.1 cm, weight: 63.7 ± 8.9 kg, mean ± SD) participated in this study. It tested the proprioception of their knee flexion/extension and ankle dorsi/plantarflexion, along with cutaneous sensitivity at the great toe, first and fifth metatarsals, arch, and heel, and the muscle strength of their ankle dorsi/plantarflexion and hip abduction. The Berg Balance Scale (BBS) and the root mean square (RMS) of the center of pressure (CoP) were collected as indications of dynamic and static balance control. A partial correlation was used to determine the relationship between the measured outcomes variables (BBS and CoP-RMS) and the proprioception, cutaneous sensitivity, and muscle strength variables.ResultsProprioception of ankle plantarflexion (r = –0.306, p = 0.002) and dorsiflexion (r = –0.217, p = 0.030), and muscle strength of ankle plantarflexion (r = 0.275, p = 0.004), dorsiflexion (r = 0.369, p < 0.001), and hip abduction (r = 0.342, p < 0.001) were weakly to moderately correlated with BBS. Proprioception of ankle dorsiflexion (r = 0.218, p = 0.020) and cutaneous sensitivity at the great toe (r = 0.231, p = 0.041) and arch (r = 0.285, p = 0.002) were weakly correlated with CoP-RMS in the anteroposterior direction. Proprioception of ankle dorsiflexion (r = 0.220, p = 0.035), knee flexion (r = 0.308, p = 0.001) and extension (r = 0.193, p = 0.040), and cutaneous sensitivity at the arch (r = 0.206, p = 0.028) were weakly to moderately correlated with CoP-RMS in the mediolateral direction.ConclusionThere is a weak-to-moderate relationship between proprioception and dynamic and static balance control, a weak relationship between cutaneous sensitivity and static balance control, and a weak-to-moderate relationship between muscle strength and dynamic balance control.     

Taijiquan and the Body without Organs: a holistic framework for sport philosophy

This paper examines and contrasts the Chinese notion of ‘inside-outside connectivity’ emphasized in Taijiquan studies with French philosopher Gilles Deleuze’s concept of ‘Body without Organs.’ Pursuing this dialogue while relating this to sport redresses a lack of novel thought and linkages with contemporary thought in Chinese scholarship, and most interestingly for sport, opens new lines of inquiry that help redefine our bodies as holistic sites of performance.

论体育个体功能的历史演化

体育对于人类个体的存在具有多方面的意义、功能。但在不同历史时期 ,体育具有不同的功能(主要指个体功能 ) ,呈现出历史性 ,其早期表现为满足人类本能需要的功能 ,近代则突出了促进身心和智力发展的功能 ,现代则转向满足健康和审美需要。本文试图通过对体育发展过程的剖析 ,揭示出体育个体功能的历史演化。     

人体语言用于体操教学的实验研究

将人体语言，即人的动作、姿态、举止等信息，引入女子单杠骑撑前回环普修课教学中，并采用对比实验法进行教学实验，以此探寻运用人体语言在体操教学中的作用。经实验得知：人体语言用于体操教学将有利于学生理解和掌握动作技术，在一定程度上降低学生动作测验时的焦虑水平，促使学生保持稳定情绪，加快教学进度，提高教学质量。

论赫胥黎《美丽新世界》中的异化逻辑

阿道司·赫胥黎的经典反乌托邦小说《美丽新世界》中潜藏着一套完整的、自上而下的、由内而外的异化逻辑,具体表现为“福特主义”意识形态塑造、整饬日常生活与时空经验、规训身体与享乐成瘾这三个步骤。这套异化逻辑勾勒出人的精神及身体的异化危机,预示着赫胥黎的警告。
