This study aimed at identifying the effects of self-paced cycling on the cognitive and functional status and fall risk on institutionalized older adults without cognitive impairment. A total of 39 individuals were randomly assigned to an exercise group or to a control group. The exercise group participants cycled at their self-selected intensity at least for 15 min daily during 15 months. The control group participants performed recreational activities. The Mini-Mental State Examination, Fuld object memory evaluation, and symbol digit modality test were used for cognitive assessments. The Katz index, the timed “Up & Go” test, and the World Health Organization questionnaire were used to assess functional independence, mobility, and fall risk. Significant improvements were observed in the exercise group for global cognition and attention, visual scanning, and processing speed. Long-term self-paced cycling training seems to have a protective effect on cognitive status and attention, visual scanning, and processing speed in older institutionalized individuals.
