This study was to investigate the impacts of senior brain heath exercise (SBHE) program for 12 weeks to basic active physical fitness, cognitive function and brain derived neurotrophic factor (BDNF) in elderly women.
Subject of this study is total of 24 women in the age of 65-79 who can conduct normal daily activity and communication but have not participated in regular exercise in recent 6 months. The study groups were divided into an exercise group (EG, n=13) and a control group (CG, n=11). The exercise program was consisted of SBHE, and training frequency was 4 times weekly, of which training time was a total of 50 minutes each time in level of intensity of 9-14 by rating of perceived exertion (RPE).
First, 12-week SBHE program has shown statistical increase in basic physical fitness in the EG comparing with the CG, such as lower body strength, upper body strength and aerobic endurance, but not in flexibility, agility and dynamic balance. Second, in the case of Mini-mental state examination Korean version (MMSE-K) and BDNF, it showed that there was a statistically significant increase in the EG comparing with the CG.
In this study, 12-week SBHE program has resulted in positive effect on change of basic physical fitness (strength and aerobic endurance), cognitive function and BDNF. If above program adds movements that can enhance flexibility, dynamic balance and agility, this can be practical exercise program to help seniors maintain overall healthy lifestyle.
本研究旨在调查为期12周的老年脑健康锻炼（SBHE）计划对老年女性基本身体活动能力、认知功能和脑源性神经营养因子（BDNF）的影响。
本研究的对象为24名年龄在65 - 79岁之间、能够进行正常日常活动和交流但在最近6个月内未参加过常规锻炼的女性。研究组分为运动组（EG，n = 13）和对照组（CG，n = 11）。运动计划由SBHE组成，训练频率为每周4次，每次训练时间共计50分钟，主观用力程度分级（RPE）为9 - 14级。
首先，与CG组相比，为期12周的SBHE计划使EG组的基本身体素质在统计学上有所提高，如下肢力量、上肢力量和有氧耐力，但柔韧性、敏捷性和动态平衡能力未提高。其次，在韩国版简易精神状态检查表（MMSE - K）和BDNF方面，与CG组相比，EG组在统计学上有显著提高。
在本研究中，为期12周的SBHE计划对基本身体素质（力量和有氧耐力）、认知功能和BDNF的变化产生了积极影响。如果上述计划增加能增强柔韧性、动态平衡和敏捷性的动作，这可以成为帮助老年人维持整体健康生活方式的实用运动计划。
