Study shows benefits of aerobic exercise for cerebral vascular health
A year of aerobic exercise training reduced impedance (effective resistance to blood flow) in the blood vessels of the brains of older adults, according to a new study from the University of Texas Southwestern Medical Center and Texas Health Presbyterian Hospital in Dallas. The results are published ahead of print in the Journal of Applied Physiology, and the study has been selected as an APSselect article for November. “These results demonstrate the benefits of aerobic exercise for cerebral vascular health, which is essential for maintaining brain function as we age.” -;Rong Zhang, PhD Older adults have higher cerebrovascular impedance than younger people, resulting in a chronic reduction in stroke surge...

Older adults have higher cerebrovascular impedance than younger people, which may contribute to a chronic reduction in brain stroke. A lifestyle with little to no exercise can lead to many negative health effects, including:
- Fettleibigkeit
- Herzkrankheiten
- Diabetes
For this study, researchers examined 73 older adults who were randomly divided into two groups. The volunteers, aged 60 to 80, walked and jogged briskly to measure the effects of exercise on blood flow to the brain. The intensity of the training program was based on each participant's fitness and was gradually increased from three training sessions per week for 25 to 30 minutes to four to five sessions per week by week 26 as participants adjusted to the previous workload.
The results of this study suggest that prolonged aerobic exercise may prevent or reduce age-related increases in cerebrovascular impedance.
These results demonstrate the benefits of aerobic exercise on cerebral vascular health, which is essential for maintaining brain function as we age.”
