Exercise substantially increases blood flow to the brain.
Some studies report that specific exercise regimens improve cerebrovascular function and blood flow velocity in older adults, while other clinical investigations note no substantial change in cerebral blood flow volume following certain training programs.

Tai Chi exercise improves age‐associated decline in cerebrovascular function: a cross‐sectional study. 2021. https://doi.org/10.1186/s12877-021-02196-9
Abstract Background Tai Chi exercise has been reported to enhance physical and mental health in the older adults; however, the mechanism remains elusive. Trial design We recruited 289 older adults practicing Tai Chi for over 3 years, together with 277 age-matched older and 102 young adults as controls. 168 Tai Chi practitioners were successfully matched to 168 older controls aged 60–69 based on a propensity score for statistics. Methods Cerebrovascular function was evaluated by measuring the hemodynamics of the carotid artery. Spearman correlation was performed to validate the age-associated physiological parameters. Results Cerebrovascular function in older adults significantly degenerated compared with the young, and was substantially correlated with age. Compared with the older control group, Tai Chi practitioners showed significant improvements in CVHI (cerebral vascular hemodynamics indices) Score (P = 0.002), mean blood flow velocity (P = 0.014), maximal blood flow velocity (P = 0.04) and minimum blood flow velocity (P < 0.001), whereas the age-related increases in pulse wave velocity (P = 0.022), characteristic impedance (P = 0.021) and peripheral resistance (P = 0.044) were lowered. Conclusions These data demonstrate a rejuvenation role of Tai Chi in improving the age-related decline of the cerebrovascular function.

PHYSICAL TRAINING EFFECTS ON LARGE ARTERY HEMODYNAMICS AND EXERCISE CAPACITY IN ELDERLY PATIENTS WITH ARTERIAL HYPERTENSION. 2011. https://russjcardiol.elpub.ru/jour/article/view/1139
Aim. To assess the effects of a complex treatment programme including the “free load choice” cycling training (FLC–CT) on exercise capacity and large artery hemodynamics in elderly in-patients with arterial hypertension (AH). Material and methods. The study included 81 patients with Stage II (39,5%) or Stage III (60,5%) AH (mean age 75,6±0,7 years). In total, 50 patients received pharmacotherapy plus FLC–CT. After the treatment, exercise capacity, hemodynamics in common carotid artery (CCA), brachial artery (BA), and femoral artery (FA) (duplex ultrasound), and endothelial function (compression test) were assessed. Results. In elderly AH patients, the treatment programme including FLC–CT was more effective than pharmacotherapy in terms of exercise capacity improvement, assessed by veloergometry. An increase in 6-minute walk test distance was observed for the FLC–CT group only. Patients not receiving FLC–CT demonstrated decreased cerebral blood flow in all hemodynamic phases, without an increase in FA blood flow volume. FLC–CT was associated with increased leg blood flow in the rapid phase, without any substantial changes in cerebral blood flow volume. Endothelial reaction in compression test was substantially decreased at baseline and did not change substantially in both treatment groups. Conclusion. Adding FLC–CT to the complex treatment of elderly AH patients improves leg hemodynamics and more effectively increases exercise capacity than pharmaceutical treatment only.
