Studies of long-term exercise maintenance after an acute cardiac event have been conducted almost exclusively with men, and the findings cannot be generalized to women.
The aim of this study was to identify women's exercise patterns and adherence to recommended exercise maintenance after a cardiac rehabilitation (CR) program.
Forty women who had a myocardial infarction or had undergone coronary artery bypass graft (CABG) surgery were recruited through convenience sampling immediately after completion of a phase II CR program. Exercise frequency, duration, and intensity were measured using wristwatch heart rate (HR) monitors during exercise for 3 months.
Results indicated that 12 of 40 (30%) women exercised five times or fewer during the 3-month study period. Only 11 women (27.5%) exercised three or more times per week. Women exercised an average of 5.2 sessions within their target HR during the entire study period. Maintenance of exercise dropped consistently during the course of the study. Although 83% of the participating women started exercising during the first month, after 1 month one third of the participants had stopped exercising. During the last week of the study, only 50% of the women were still exercising.
These findings indicate the women are exercising well below the recommended guidelines for exercise after acute cardiac events.
急性心脏事件后长期运动维持的研究几乎完全是针对男性进行的，其研究结果不能推广到女性。
本研究的目的是确定女性在心脏康复（CR）计划后的运动模式以及对推荐的运动维持的依从性。
通过便利抽样，在40名患有心肌梗死或接受过冠状动脉搭桥术（CABG）手术的女性完成II期CR计划后立即招募她们。在3个月的运动期间，使用腕式心率（HR）监测器测量运动频率、持续时间和强度。
结果表明，在3个月的研究期间，40名女性中有12名（30%）运动次数为5次或更少。只有11名女性（27.5%）每周运动3次或更多次。在整个研究期间，女性在目标心率范围内平均运动5.2次。在研究过程中，运动维持率持续下降。虽然83%的参与女性在第一个月开始运动，但1个月后三分之一的参与者停止了运动。在研究的最后一周，只有50%的女性仍在运动。
这些发现表明，女性的运动情况远低于急性心脏事件后推荐的运动指南。
