Abstract:
Some individuals, despite having normal resting blood pressure, exhibit an exaggerated blood pressure response during exercise, indicating a potential risk for future hypertension. This study aimed to investigate how different individual blood pressure responses to exercise affect cerebral circulation and exercise-induced acute cognitive changes in young, healthy individuals. To eliminate the influence of aging and disease, thirty young, healthy individuals (aged 21 ± 1 years) participated in this study. They performed an interval static handgrip exercise protocol, during which arterial blood pressure (ABP), cognitive function, and middle cerebral artery blood velocity (MCA V), as an index of cerebral blood flow, were measured. Cognitive function was assessed using the Go/No-go test before exercise and 3 min after exercise completion. Individual changes in systolic blood pressure (SBP) were significantly and linearly related to the decrease in reaction time during a cognitive task, indicating cognitive improvement following exercise (p < 0.01). Importantly, in the top 10 subjects with the highest SBP responses (n = 10, + 38 ± 8 mm Hg), this cognitive improvement was not statistically significant (p = 0.32). These findings suggest that an exaggerated ABP response to exercise may compromise acute cognitive enhancements induced by exercise in young individuals.

Exercise and Cardiovascular Response
Light to moderate physical activity initiates a series of interconnected responses in the body. The heart rate modestly increases in anticipation of the workout, followed by widespread vasodilation as oxygen consumption by skeletal muscles increases. This results in decreased peripheral resistance, increased capillary blood flow, and accelerated...

Exercise Stress Test
Exercise stress testing, commonly known as a treadmill test, is a noninvasive procedure used to evaluate cardiovascular function and diagnose heart conditions.
Definition
An exercise stress test measures the heart's response to exertion using a treadmill or stationary bicycle. Chest electrodes record the heart's electrical activity through an ECG, and blood pressure is monitored regularly.
