Background To understand the relationship between blood pressure changes during
standing up and clinical outcome, cerebral oxygenation needs to be measured, which may …

Cerebral hemodynamics, eg, cerebral blood flow, can be measured and quantified using
many different methods, with transcranial Doppler ultrasound (TCD) being one of the most …

The process by which cerebral blood flow (CBF) remains approximately constant in
response to short-term variations in arterial blood pressure (ABP) is known as cerebral …

The number of research studies investigating whether similar or different cardiovascular
responses or adaptations exist between males and females is increasing. Traditionally …

Introduction Lower body negative pressure (LBNP) eliminates the impact of weight-bearing
muscles on venous return, as well as the vestibular component of cardiovascular and …

Moderate-intensity aerobic exercise increases cerebral blood velocity (CBv) primarily due to
hyperpnea-induced vasodilation; however, the integrative control of cerebral blood flow …

A reciprocal relationship between the baroreflex and cerebral autoregulation (CA) has been
demonstrated at rest and in response to acute hypotension. We hypothesized that the …

Introduction. The effect of concurrent head-up tilt and lower body negative pressure (LBNP)
have been examined on middle cerebral artery velocity (MCAv) at rest; however, it is …

Background Estrogen and progesterone levels undergo changes throughout the menstrual
cycle. Existing literature regarding the effect of menstrual phases on cardiovascular and …

Objective. To evaluate sex differences in the reliability of absolute and relative cerebral
blood velocity (CBv) during concurrent supine cycling with lower body negative pressure …
