The aim of the study was to determine the effect of regular participation in home-based exercise programme on cognitive functioning changes in institutionalised older adults. Two groups of participants were recruited for the study: experimental (n = 17) in mean age 76 ± 5.6 years, who participated in home-based exercise program and control (n = 14) in mean age 80 ± 4.2 years. The standardised Stroop Color-Word Test-Victoria version (VST) was used to measure the level of cognitive functions. Group differences were analyzed with Mann-Whitney U-test for independent samples and for differences between pre-measurements and post-measurements on experimental and control group we used non-parametric Wilcoxon Signed - Rank Test. The level of significance was α < 0.05. Application of 3-months home-based exercise program significantly improved the cognitive functions only in one (Word condition; p<0.01) from three VST conditions in institutionalised older adults. That’s why we recommend longer participation in home-based exercise program, at least 6- months, with combination of various types of cognitive interventions, like concepts of cognitive training, cognitive rehabilitation, and cognitive stimulation to improve cognitive functioning in older adults living in old peoples’ homes.
