ABSTRACT
@#ObjectiveTo observe the effect of sport walking on heart and lungs functions in old women.MethodsForty-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.ResultsAfter 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)s to (0.128±0.049)s ( P<0.01).ConclusionSport 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.
