Abstract

<p>Objective: We conducted an exercise intervention program for frail female older adults and examined the effects of the program on their self-perceived health, focusing on their nutritional status.</p><p>Methods: The participants were 107 frail female older adults aged 70 years and older, excluding those who dropped out and those whose physical functions could not be measured. An exercise intervention session was conducted twice a week for a total of 18 times over 9 weeks. We assessed physical function tests, self-perceived health using questionnaires, and nutritional status assessments before and after the program intervention. The participants were stratified into three groups: good, fair, and poor.</p><p>Results: All three groups showed improvement in self-perceived health after the program. Multiple comparisons showed that the effect of the program on self-perceived health was significantly higher in the poor nutrition group than in the good nutrition group. Comparison of physical function assessment by nutritional status showed an interaction between the three groups in knee extension strength. The poor nutrition group had a higher intervention effect on self-perceived health than the good nutrition group.</p><p>Conclusion: It was suggested that self-perceived health in the frail elderly with a poor nutritional status (MNA-SF score, ≤ 11 points) can be improved by an exercise intervention program.</p>
