有氧健身操对亚健康中老年女性健身作用的探讨

目的 通过自行设计的有氧健身操,观察对亚健康中老年女性的健身作用。方法 采用改良Bruce方案功率车 运动试验,观察锻炼组30例,对照组30例在运动前中后的心电变化来确定有氧健身操的最佳负荷,探讨有氧健身操对心脏功 能、体重指数、脂肪百分比的影响及腰臀围之比(WHR)与运动功能的关系。结果 锻炼组安静时心率明显低于对照组,最高 心率及心率储备两组间差异具显著性(P<0.05),锻炼组与对照组间WHR差异也具显著性(P<0.05)。锻炼组锻炼前后 血压、体重指数、脂肪百分比均有明显降低。结论 锻炼对心血管系统有良好的治疗作用,有氧健身操锻炼可改善中老年女 性WHR,减少腰部的脂肪堆积,降低血压、体重指数、脂肪百分比,增强运动能力。中老年女性WHR与运动能力呈负相关。

Effects of aerobic exercise on subhealth women of middle or elderly age

Objective To investigate the effects of aerobic exercise on the cardiac function and WHR in subhealth women of middle or elderly age. Methods The aerobic exercise were designed. The training group (n=30) was given physical traning of 90 min per time, 5 times per week. The control group (n=30) was not given any traning. Results It showed maximum heart rate, rest heart rate and blood pressure in training group were lower than those control group. The exercise ability in training group improved. (P<0.05 ) Conclusions Long term exercise could induce the improvement of WHR in subhealth women of middle or elderly age,decrease fat deposition in waist and abdomen, improve cardiac function and muscle movement. There was a negative corelation between WHR and exercise ability in women of middle or elderly age.
