Effects of dual task exercise on functional fitness and activation of cognitive control in frail older adults

Abstract

[Purpose] The purpose of study was to determine the effects of a 12-week dual task exercise using MOTOTILE on functional fitness and cognitive control in frail older adults. [Participants and Methods] Pre-test, the 36 participants (mean age, 75 years old) were assigned to two groups based on Mini Mental State Examination (MMSE) scores: group 1 (n=27), 27 points or more, and group 2 (n=9): 26 points or less. All subjects performed a dual task exercise. Functional fitness and cognitive control were assessed at pre-and post-test. [Results] Significant differences in time effect were noted for the timed up & go test, stepping, five-repetition sit-to-stand test, toe grip strength, Flanker task and Stroop task, but there were no significant differences between the two groups in improvement rates or magnitudes of change. [Conclusion] MOTOTILE dual task exercise programs seem effective in improving lower body function and cognition in frail older adults.
