Aerobic exercise may boost brain blood vessel health in older people

In a study from the University of Texas and elsewhere, scientists found a year of aerobic exercise training reduced impedance (effective resistance to blood flow) in the brain blood vessels of older adults.

Older adults have higher cerebrovascular impedance than younger people, which might contribute to a chronic reduction of blow floods in the brain.

A lifestyle with little to no exercise can lead to many adverse health effects, according to the National Library of Medicine, including obesity, diabetes, and heart disease.

In the study, researchers examined 73 older adults randomly split into two groups for this study.

The volunteers, ages 60 to 80, engaged in brisk walking and jogging to measure the impact of exercise on brain blood flow.

The intensity of the exercise program was based on each participant’s fitness and progressively increased from three exercise sessions per week for 25 to 30 minutes to four to five sessions per week by week 26, as participants adapted to previous workloads.

The findings suggest prolonged aerobic exercise training may prevent or reduce age-related increases in cerebrovascular impedance.

The team says these findings demonstrate the benefits of aerobic exercise on brain vascular health, which is essential to maintain brain function in old age.
