THURSDAY, May 14, 2020 (HealthDay News) — A six-month aerobic exercise intervention is associated with improvements in cognitive domains and cerebrovascular regulation among middle-aged and older adults, according to a study published online May 13 in Neurology<\/i>.<\/p>\n
Veronica Guadagni, Ph.D., from Dalhousie University in Halifax, Nova Scotia, Canada, and colleagues enrolled 206 healthy low-active middle-aged and older adults in a six-month aerobic exercise intervention in a single-group pre\/postintervention study. Cerebral blood flow velocity was measured with transcranial Doppler ultrasound. The association between changes in cognition and changes in cerebrovascular function was examined.<\/p>\n
The researchers observed improvements in some cognitive domains, cardiorespiratory fitness, and cerebrovascular regulation in association with the intervention. There was a negative association seen for changes in executive function with changes in cerebrovascular resistance index (CVRi) during submaximal exercise (\u03b2 = \u22120.205), while positive associations were seen for fluency improvements with changes in CVRi during hypercapnia (\u03b2 = 0.106).<\/p>\n
“Results from this study provide suggestive evidence that aerobic exercise has the potential to improve cognitive performance and cerebrovascular regulation in middle-aged and older adults, but future appropriately powered randomized controlled trials are needed to test the specific effects of aerobic exercise on cognition,” the authors write.<\/p>\n
