Exercise is an important strategy for preventing chronic diseases and promoting the health of older adults. The purpose of this research was to evaluate the effects of an outdoor walking exercise program on the cardiorespiratory function, the flexibility, and the emotional state of elderly Korean women. A nonequivalent control group, pretest-posttest design was used to measure the effects of the exercise program. The subjects were 27 females between the ages of 60 to 75 years. The intensity of the walking program was 40-60% of the target heart-rate with a duration of 50-60 min, 3 times per week at an outdoor track for 8 weeks. The effects of the program were assessed by maximal oxygen uptake (VO2max), resting pulse rate, blood pressure Forced Vital Capacity (FVC), Forced Expiratory Volume per 1 second (FEV1) for cardiorespiratory function, the "sit and reach test" for flexibility, and by the Profile of Mood States (POMS) for emotional state. The physical function and the emotional state of the experimental group improved significantly more than that of the control group except FEV1 and the anger factor of POMS. The VO2max and the flexibility of elderly women in the experimental group progressively improved as the duration of the exercise period continued. The results of this study suggest a practical and easy method of exercise to enhance the health of older women.
运动是预防慢性病和促进老年人健康的重要策略。本研究的目的是评估户外步行锻炼计划对韩国老年女性心肺功能、柔韧性和情绪状态的影响。采用非等效对照组、前测-后测设计来测量锻炼计划的效果。受试者为27名年龄在60至75岁之间的女性。步行计划的强度为目标心率的40%-60%，持续时间为50-60分钟，每周在户外跑道进行3次，共8周。通过最大摄氧量（VO2max）、静息脉搏率、血压、用力肺活量（FVC）、第1秒用力呼气量（FEV1）评估心肺功能，通过“坐位体前屈测试”评估柔韧性，通过情绪状态量表（POMS）评估情绪状态。除了FEV1和POMS的愤怒因子外，实验组的身体功能和情绪状态改善明显超过对照组。随着运动时间的持续，实验组老年女性的VO2max和柔韧性逐渐提高。本研究结果表明了一种切实可行且简便的运动方法，可增进老年女性的健康。
