摘要:
[目的]探讨广场舞与健身走运动对中老年女性心血管功能的影响,为中老年人科学锻炼提供理论依据.[方法]选择90名中老年女性作为实验对象,随机分为广场舞30人、健身走30人与对照组30人,每组中年女性与老年女性的人数比例为1∶1;进行3个月的运动干预,实验前后检测心脏功能与血管状态,包括脉率(HR),左心负荷指数(SPTI),心肌灌注指数(DPTI),心内膜下心肌活力率(SEVR),射血时间(ED),收缩压(SBP),舒张压(DBP),脉压差(PP),中心动脉压(CAP)与增长指数(AI).[结果]锻炼3个月后,组内实验前后比较,广场舞与健身走静息HR(P<0.01),SPTI(P<0.01),ED(P<0.01),SBP(P<0.01),DBP(P<0.01),PP(P<0.01)与CAP(P<0.05)下降,DPTI(P<0.01)与SEVR(P<0.01)升高,AI无显著性变化(P>0.05);对照组各项指标实验前后均无显著性变化(P>0.05).组间差值比较,广场舞组多项指标的上升与下降幅度好于健身走组与对照组(P<0.05);健身走组多项指标的上升与下降幅度好于对照组(P<0.05);广场舞老年组改善效果好于健身走中老年组与对照中年组;健步走老年组运动效果也要好于对照中年组.[结论]广场舞与健身走对中老年女性心血管指标均有不同程度的改善;广场舞锻炼对中老年女性心血管指标的改善效果要好于健身走锻炼.
[Objective]The purpose of the study is to assess the effect of square dance and fitness walking exercise on cardiovascular function in middle-aged and older women,and to provide theoretical basis for scientific exercise of middle-aged and older people.[Methods]90 middle-aged and older women were selected and randomly divided into 3 groups:square dance group,fitness walking group and control group with 30 women in each group.The proportion of middle-aged and older women was 1∶1 in each group.Exercise intervention was conducted for three months,and cardiac function and vascular status were measured before and after experiment,including pulse rate(HR),left cardiac load index(SPTI),myocardial perfusion index(DPTI),Subendocardial viability ratio(SEVR),ejection time(ED),systolic pressure(SBP),diastolic blood pressure(DBP),pulse pressure(PP),central arterial pressure(CAP)and growth index(AI).[Results]By comparing the results among groups before and after the experiment after 3 months of exercise,the default-mode HR of square dance and fitness walking exercise(P<0.01),SPTI(P<0.01),ED(P<0.01),SBP(P<0.01),DBP.(P<0.01),PP(P<0.01)and CAP(P<0.05)decreased,DPTI(P<0.01)and SEVR(P<0.01)increased,and there was no obvious change in AI(P>0.05);there were no obvious change in all indexes of control group before and after the experiment(P>0.05).By comparing of the differences among groups,the increase and decrease of multiple indexes of square dance group were better than those of fitness walking exercise group and control group(P<0.05);the increase and decrease of multiple indexes of fitness walking group were better than that of control group(P<0.05);the improvement effect of square dance group in older people was better than fitness walking exercise group in middle-aged and older people and no exercise in middle-aged group.The exercise effect of fitness walking exercise group in older people elderly was also better than the middle-aged group without exercise.[Conclusion]The square dance and fitness walking exercise can improve the cardiovascular indexes of middle-aged and older women to different degree.The improvement effect of square dance on cardiovascular indexes of the middle-aged and older women is significant better than fitness walking exercise.
