Modeling and simulating human cardiovascular response to acceleration
The human cardiovascular system routinely encounters conditions that cause it to adapt. For example, when an astronaut enters microgravity, his/her cardiovascular system adapts rapidly to the weightless environment with no functional impairment. This adaptation is entirely appropriate while in …

Computational models of cardiovascular response to orthostatic stress
The cardiovascular response to changes in posture has been the focus of numerous investigations in the past. Yet despite considerable, targeted experimental effort, the mechanisms underlying orthostatic intolerance (OI) following spaceflight remain elusive. The number of hypotheses still under …

THE RELATIONSHIP BETWEEN AEROBIC TRAINING AND CARDIOVASCULAR RESPONSE TO EXERCISE
… the relationship between hypervolemia and cardiovascular adaptations to aerobic exercise a series of cross-sectional and longitudinal studies were performed. Study 1 examined cardiovascular response of trained runners (n=15) and untrained males (n=l 5) at rest and during exercise while …

Emotion Regulation and Cardiovascular Response to Emotion Provocation: Reappraisal versus Suppression
… the subjective, behavioral and physiological responses to emotional experiences. Within the emotion regulation model, reappraisal and suppression are two strategies that have been studied extensively. However, this research has largely ignored the effects of individual differences in emotion …

Acute Cardiovascular Response and Perception of Effort Between the Super Slow and Gold Standard Resistance Training Protocols
… than traditional resistance training and improve cardiovascular measures above aerobic exercise. However, whether this type of training is safe for the older, possibly hypertensive population to which it is being targeted is questionable. To help provide an answer to this question the purpose of …

Exploring the Cardiovascular Response to Anger Imagery and Speech in Vietnam Veterans With and Without Posttraumatic Stress Disorder
… The current study explored the patterns of cardiovascular responding associated with varying anger induction methods, specifically personal anger memory recall through verbalization versus imagery in a sample of Vietnam combat veterans with and without Posttraumatic Stress Disorder (PTSD). …

Moderating effect of a single aerobic exercise session on the cardiovascular response to a stressful procedure 45 minutes later
… of 30 minutes of aerobic exercise in reducing cardiovascular reactivity to a subsequent stressor compared to a nonexercise attention control condition in 16 males (<u>m</u> age = 21 yrs; moderate activity level; positive family history for hypertension) using a within subject design. The order …

Acute Cardiovascular Response to Low-Load Unilateral, Bilateral, and Alternating Resistance Exercise with Blood Flow Restriction in the Lower Body
… suggested to exaggerate the exercise pressor response over traditional non-BFR exercise. While applying BFR relative to an individual’s arterial occlusion pressure (AOP) and exercising at low-loads seems to produce a comparable cardiovascular response to traditional moderate or high-load …

PTSD Subtypes, Depressive Presentation, Dissociation, and Cognitive Appraisals and Their Impact on Cardiovascular Reactivity Responses to Stress
… (MDD) are related to an increased risk for cardiovascular disease (CVD), with links to ischemic heart disease, myocardial infarction, cardiac mortality, and other cardiac conditions. Given that these disorders are associated with increased medical costs, disability, and employer burden, …

Exercise Pressor Reflex Dysfunction in Hypertension
… WKY rats recapitulates the exaggerated cardiovascular response elicited by both mechanically and metabolically sensitive afferent neurons in hypertension. Importantly, we demonstrated that experimentally increasing NO production within the NTS of hypertensive SHR rats partially corrects …

Acute arterial responses to physiological and psychological stress
Cardiovascular disease is the leading cause of death in the western world. As accumulating evidence emerges that risk of developing cardiovascular disease increases with higher levels of blood pressure, the early detection of those with hypertension becomes an increasing priority. Blood pressure is …

Cardiovascular Fitness of Horses Conditioned by Treadmill Work
… of submaximal treadmill conditioning on the cardiovascular response to a standard exercise test (SET). Parameters measured included heart rate, cardiac output, stroke volume, packed cell volume, lactic and pyruvic acid concentrations, blood gases and blood pH. In all three experiments, the …

Understanding Autonomic Control via Human Deep Brain Stimulation
… on the control of the respiratory and cardiovascular systems both alone and in combination in the context of exercise. Deep Brain Stimulation (DBS) is a type of therapy in patients in which electrodes are inserted into the brain to treat neurological disorders such as Parkinson’s …

Exercise response and the effect of supplemental oxygen during interval training on O2 uptake kinetics, blood lactate levels, and endurance performance in patients with mild, moderate and severe cystic fibrosis
… mechanical limitation, arterial hypoxemia, cardiovascular abnormalities, alteration in O2 uptake kinetics and reduced muscle strength may contribute to the reduced exercise performance in individuals with CF patients. The purpose of this research was to compare the exercise response in …

Hostility and Cardiovascular Regulation: An Investigation of Lateralized Pre-Motor Functions
… physiological correlates of hostility, such as cardiovascular lability and increased risk of cardiovascular disease, are vital when considering the possible health risks associated with high levels of hostility (Henry & Meehan, 1981; Matthew & Haynes, 1986; Johnson, 1990; Heller, 1993; Heilman, …
