摘要
目的观察健走锻炼对老年女性心肺功能的影响。方法指导42名60～69岁的健康老年女性进行为期4个月的健走锻炼,根据心率控制行走速度和运动强度,试验前后分别测定受试者的心脏泵血功能、肺通气功能及脑阻抗血流图等。结果锻炼后,受试者的心脏泵血功能明显改善,每搏输出量由锻炼前的(65.22±11.41)ml增加到(72.10±10.78)ml;射血分数由(60.10±5.03)%增至(68.78±6.25)%;而心率则由(77.45±8.69)次/min减慢至(67.89±8.21)次/min;肺活量及每分钟最大通气量分别由(2.86±0.36)L和(96.14±15.21)L提高到(3.34±0.53)L和(114.02±16.01)L,锻炼前后相比均有非常显著性差异(P<0.01),反映脑血流阻力的指标流入时间由锻炼前的(0.171±0.058)s缩短至(0.128±0.049)s,亦有非常显著性差异(P<0.01)。结论适当强度的健走锻炼可改善老年女性的心肺功能,是一种简便易推广的健身运动项目。
Objective To observe the effect of sport walking on heart and lungs functions in old women. Methods Forty-two old women aged from 60 to 69 had sport walking for 4 months; the speed and intensity were controlled according to their heart rate respectively. The indexes of respiration, circulation and rheoencephalography were measured before and after exercise. Results After exercise, blood-pumping function of heart improved obviously, stroke volume increased from （65.22±11.41）ml to （72.10±10.78） ml, ejection fraction increased from （60.10±5. 03）% to （68.78±6.25）%, while heart rate declined from （77.45±8. 69） times/ min to （7.89±8.21）times/min, capacity increased from （2.86_±0.36）L to （3.34±0.53）L, and maximal voluntary ventilation for every minute increased from （96. 14±15.21）L to （114.02±16.01）L, significantly different compared with that before treatment （P 〈0.01）. The fluid time of rheoencephalography reduced from （0.171±0.058）sto （0. 128±0.049）s （P 〈0.01）.Conclusion Sport walking under proper intensity can improve the function of respiration and circulation system in old women, so it is a good way to keep health for the elders.
