Abstract: Impairments in dual-task performance can be observed in healthy older adults when motor and cognitive assignments are applied simultaneously. According to the hypofrontality hypothesis, there may be a reduction in frontal cognitive function during exercise.ObjectiveThe aim of the present study was to compare the performance changes on cognitive tests of depressive elderly (n=10), healthy older adults (n=10), and healthy young individuals (n=10) during cycle ergometer exercise.MethodsThe groups were submitted t… Show more

“…During dual-task performance, significant changes were evident in all the gait variables in all the age groups. The magnitude of the reduction in the gait speed and increase in time and The findings of this study are consistent with previous studies [16][17][18][19] which observed the effects of dual task on gait parameters. The study by Andrew et al [20] observed a significant difference in gait velocity between the younger and the older group under dual tasking conditions.…”

“…Previous study suggested exercise with dual task has significant benefit on cognitive function compared to single task exercise. The dual task exercise such as digit backward test with a cycle ergometer exercise can improved performance changes on cognitive tests in young and elderly6 ) . However, from literature review, there are reports of physical function and cognitive function through implementation of dual tasks.…”

“…8,9 When the performance of one task interferes with the performance of another, a negative interaction can occur between the tasks, which leads to the individual exceeding the capacity of the resource available, even when the tasks have been previously learned or are performed automatically. 4,10,11 Thus, the danger of executing one of the tasks will be proportional to the amount of care that the other task demands. 12 Another relevant factor is that elderly individuals have greater difficulty in performing a DT than younger individuals.…”
