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.

Background: Research regarding the impact of aquatic exercise on cognition is scarce. This study aimed at identifying the effects of water-based exercise training on the cognitive function and quality of life of healthy adult women. Methods: Fifty-one healthy women [mean age: 46.5 (12.3) y] were assigned to group A or B and followed a water-based exercise program for 6 months. During the first 3 months, the sessions performed by group A were focused on stimulating cognitive function. For the next 3 months, the sessions were mainly aimed at improving physical fitness. Participants in group B followed the same program in reverse order. The trail making and symbol digit modality tests were used to assess the impact of the program on cognition. The effects of the intervention on the participants’ physical and mental health were measured by means of the medical outcomes study 36-item short-form health survey. Results: Once the intervention ended, significant improvements were observed in the participants’ cognitive function and mental health domain, regardless of the group in which they were initially included. Conclusion: Water-based exercise is a training modality capable of enhancing cognitive function and quality of life through improvements in mental health in healthy adult women.
