Background and Study Aim: Considering the elderly quality of life (QOL), cognitive functions including memory, flashback, language as well as physical health are highly important. The aim of study is the relationship between blood pressure and cognitive function and physical function through random comparison tests by developing a multi-task exercise program including simple and moderate exercise and cognitive training that can be practiced on a regular basis to the mild cognitive impairment (MCI).
Material and Methods: Twenty subjects with MCI-diagnosed hypertensive elderly women in this study and were randomly divided into one of two groups: multi-task exercise group (n = 10) and control group (n = 10). The multi-task exercise program was conducted in program for 90 minutes, two times a week for 24 weeks. Health care education program was conducted by a specialist once in a two weeks and body composition check and personal consultation were done in every other week.
Results: Body weight(p<.05) and Body Mass Index(p<.05) showed a valid difference in the interaction between the group and time. In addition, there was a valid difference in the interaction between the group and time in moderate to vigorous physical activity(p<.05), step count (p<.05), short physical performance battery (p<.05), One legged standing time (p<.01), 6-minute walking (p<.05). Moreover, a valid difference in the interaction between the group and time was shown in Korean version of Geriatric Depression Scale-short form (p<.05), Korean version of Mini Mental State Examination (p<.05) and Korean version of Montreal Cognitive Assessment (p<.05).
Conclusions: The multi-task exercise program has a positive impact on improving the body composition, physical function, blood pressure and cognitive function. In particular, maintaining the long-term regular physical activity is a critical factor for preventing the decline in cognitive function.
