Objectives To examine the effects of 12-week momentum-based dumbbell training on cognitive function, physical function, quality of life and sleep quality on older adults with mild cognitive impairment (MCI), and to explore the relationship among these changes.
Methods Forty-five community-dwelling older adults with MCI were randomly assigned to either a dumbbell training group(DTG, n=22) or a control group (CG, n=23). Participants in the DTG participated in exercise sessions 3 times weekly for 12 weeks.
Results There were significant within-group changes(improvement) in ADAS-Cog total score, instruction, MoCA and SF-36 Mental Component Summary(P < 0.05).Compared to CG, participants in the DTG significantly improved in ADAS-Cog total score, word recall and attention, MMSE, TUG and PSQI(P ≤ 0.05). And the changes in SF- 36 MCS(r=-0.712) and PSQI(r=-0.380) were significantly correlated with the changes in cognitive function.
Methods A 12-week momentum-based dumbbell training is effective for improving cognitive functions and has potential benefits for improving the physical function in older adults with MCI. These pre-post changes (mental and sleep condition) may influence the degree of cognitive benefits induced by training.
