网球锻炼对老年人平衡能力影响的实验研究

Experimental research on the effects of tennis exercise on the balance abilities of the elderly

通过公开招募16例60~69岁的男性老年人为实验对象,随机分为实验、对照组,实验组进行6个月、每周3次、60~90min/次、心率控制在110~130次/min的网球专项锻炼,对照组保持原来生活方式,实验前后测量影响平衡能力的相关指标并进行统计学处理。结果显示:实验后实验组与对照组比较,下肢力量的“坐下-站立”试验、静态平衡闭眼双足状态重心动摇轨迹长、睁眼单足状态重心动摇轨迹长、包络面积、X轴摆动速度、动态平衡步速、步态周期、步宽均呈显著性差异(P<0.05),实验组实验后明显优于实验前(P<0.05或P<0.01)。结果表明:老年人进行规范的网球锻炼能够有效增强下肢力量,提高静态平衡和动态平衡能力,增强抗跌倒能力。

By openly recruiting 16 male old people aged 60-69,the authors randomly divided them into an experiment group and a control group,let the people in the experiment group do specific tennis exercise for 6 months,3 times a week,60-90 min/time,and controlled the exercise intensity to a heart rate in the range of 110-130 beats/min,while let the people in the control group maintain their original lifestyles,measured balance ability related indexes and processed them statistically before and after the experiment,and revealed the following findings:the “sitting and standing” test on the lower limb strength,the following static balance indexes:center of gravity swaying track length measured in an eyes closed and two feet standing condition,and center of gravity swaying track length,envelope area and axis X swinging speed measured in an eyes opened and one foot standing condition,and the following dynamic balance indexes:pace,gait cycle and step width,of the people in the experiment group,showed significant differences as compared with those of the people in the control group (P<0.05);after the experiment,these data of the people in the experiment group were significantly better than those of the people in the experiment group before the experiment (P<0.05 or P<0.01).The said findings indicate that the elderly doing normative tennis exercise can effectively enhance lower limb strength,improve static and dynamic balance abilities,and enhance the fall resistance ability.
