摘要
目的:以健康中老年女性为观察对象,探讨踝关节肌力随年龄的变化特征及其与静态平衡能力的相关关系。方法:实验于2005-03/05在上海体育学院体质测试中心完成测试。选择上海杨浦区150名身体健康且体型正常女性,按年龄分为3组:40～49岁组、50～59岁组、60～69岁组,每组50名。所有受试者在国家体育总局体育科学研究所提供的Bestpoise V1.0人体平衡能力测试系统上进行一次性平衡能力的测试;在瑞士CONTREX公司提供的Contrex肌力测试系统上进行踝关节60(°)/s的等速肌力测试。观察女性踝关节肌力的年龄变化特征、平衡能力的年龄变化特征及二者的相关性。结果:150名受试者均进入结果分析。①受试者的踝关节屈肌最大力矩、屈肌最大功率与年龄呈负相关(r=-0.449,-0.451,P=0.002),且在0.01水平上相关具有高度显著性。②伸肌最大力矩/屈肌最大力矩与年龄呈正相关(r=0.516,P=0.00),且在0.01水平上相关具有高度显著性。③屈肌最大力矩、屈肌最大功率、伸肌最大力矩/屈肌最大力矩与双脚睁眼平衡能力没有显著相关性(P=0.186,0.354,0.117)。结论:①中老年女性的踝关节伸、屈肌力量的衰退有其部位和年龄特点,且在程度上也表现出不一致性;50～59岁是女性踝关节力量开始快速衰退的时期。②中老年女性踝关节伸肌和屈肌力量的衰退在60～69岁期间出现了明显的不平衡,屈肌快于伸肌。③对于40～69岁的女性来说,踝关节肌力不是影响静态平衡能力的主要因素。
AIM： To investigate the correlation between ankle strength changes and resting balance ability in healthy middle-aged and old women. METHODS： The experiment was carded out in the Physical Fitness Testing Center of Shanghai Institute of Physical Education from March to May 2005. 150 healthy women with normal body type were selected from Yangpu community, Shanghai, and divided into 40-49, 50-59 and 60-69 years groups with 50 people in each group. All subjects performed the following task： （1）balance testing was carded out by a computerized balance platform named Bestpoise V 1.0, designed and made by China Institute of Physical Education; （2）their ankle muscle strength was tested later by a computerized dynamometer named Contrex system （made by CONTREX, Sweden） under isokinetic 60 （°）/s. The change features of ankle muscle strength and balance ability with age, and their correlation were analyzed. RESULTS： 150 subjects were all involved in the result analysis. （1）The maximal torque and power of ankle flexor were negatively correlated with age （r =-0.449, -0.0451, P =0,002）, and the correlation was significant at 0.01 level. （2）The ratio of maximal torque of ankle extensor and flexor were positively correlated with age （r =0.516, P =0.00）, and the correlation was significant at 0,01 level. （3）The balance on double legs with open eyes was not significantly correlated with ankle maximal torque and power of flexor, and ratios of flexor torque and extensor torque （P =0,186, 0.354, 0.117）. CONCLUSION： （1）The decline of ankle flexor and extensor strength in middle-aged and old women shows a correlation with age and muscle place, and there is no identical rate in the decrease. 50-59 years old is the faster phase of decline in female ankle strength. （2）The reduce in flexor and extensor strength is imbalance in old women aged 60-69 years, and the speed of flexor is faster than the extensor. （3）To 40-69 years women, ankle muscle strength is not the key factor for their static balance.
