Lateralized Induction of Cardiovascular Responses: Exploring Asymmetric Autonomic Regulation
… to the regulation of autonomic nervous system responses. This study addressed that issue via the implementation of lateralized autonomic response-evoking tasks. With the use of cardiovascular and electrodermal measures, the present study indexed autonomic responses to lateralized stimuli. This …

The Cardiovascular Responses of Domestic Fowl to Elevated Ambient Temperatures
A series of experiments were performed to study cardiovascular and thermoregulatory responses of chickens during an acute heat challenge at 35(DEGREES)C ambient temperature (T(,a)). In the first experiment eight mature Single Comb White Leghorn hens, maintained at 25(DEGREES)C T(,a), were subj

The effect of skin temperature on cardiovascular responses during endurance exercise
… body skin temperature (T [subscript sk]) on cardiovascular responses and the independent effect of heart rate on stroke volume when Tsk is hot and cold during moderate intensity endurance exercise. In study 1, we systemically evaluated the effect of graded increases in T [subscript sk] from …

Ultraviolet a irradiation on human skin : nitric oxide mediated cardiovascular responses
Cardiovascular disease (CVD) such as hypertension and stroke are serious illnesses that impact on the lives of millions all over the world, with 972 million (26% of the world’s population) suffering from hypertension in year 2000, and an estimated 1.56 billion to be affected by 2025. Hypertension, …

Racial differences in cardiovascular responses following an acute bout of aerobic exercise
… Caucasians (CA) for developing hypertension, cardiovascular disease, stroke and renal disease. An acute bout of moderate aerobic exercise causes a sustained reduction in blood pressure (BP), termed post-exercise hypotension (PEH) in CA. Histamine receptors 1 and 2 (H1R and H2R) have been shown …

The effect of acute intradialytic exercise on cardiovascular responses in hemodialysis patients
… of IDEX by examining its effect on intradialytic cardiovascular (CV) hemodynamics. Intradialytic changes in brachial, aortic and cardiac hemodynamics and autonomic function were examined during a normal HD session without exercise, or when 30-minutes of cycling exercise was performed during the …

CARDIOVASCULAR RESPONSES TO ACUTE EXERCISE IN ANTHRACYCLINE TREATED CANCER SURVIVORS AND HEALTHY CONTROLS
… the objective of this study was to compare cardiovascular responses, at rest and peak exercise, in anthracycline treated cancer survivors (ATS) and age-matched healthy controls (CON) to examine potential mechanisms of exercise intolerance. METHODS: Ten ATS, four males and six females, that …

The influence of pregnancy upon acute cardiovascular responses to slow and deep breathing.
… it is important to understand whether normal cardiovascular changes that accompany pregnancy influence the acute responses to SDB. Additionally, known structural and mechanical differences in the respiratory systems of men and women may also influence cardiovascular responses to SDB. As most …

Analysis of Quantitative Electroencephalographic and Cardiovascular Responses to Stress Amoung Low- and High-Hostiles
… to identify higher cortical correlates of cardiovascular arousal. Low- and high-hostile, right-handed, undergraduate men were identified using the Cook Medley Hostility Scale (CMHS). All participants (N = 30) completed the cold pressor paradigm. Cardiovascular (heart rate, systolic blood …

Cardiovascular responses to two minutes of isometric contractions of the finger flexors in healthy women
The purpose of this study was to investigate the cardiovascular responses to prolonged submaximal (20% MVC) and maximal (100% MVC) isometric contraction of the finger flexors in healthy women between the ages of 20 and 35 years. The cardiovascular variables which were investigated included; heart …

The Integrative relationship between insulin and insulin-like growth factor 1 induced cardiovascular responses and sympathetic nervous responses
… and exert similar metabolic as well as cardiovascular actions. Insulin and IGF-l have been demonstrated to decrease cardiovascular tone and increase blood flows in skeletal muscle. Insulin has also been showed to increase sympathetic nerve activity that may play a role in the regulation …

The Cardiovascular Responses of Running on an Underwater Treadmill at Two Different Water Temperatures Compared to Land Based Running
… The purpose of this study was to examine the cardiovascular responses of oxygen consumption (VO2) and heart rate (HR) that occur when running on an underwater treadmill in 95° and 104° water temperatures compared to a land-base treadmill trial (LTM). METHODS: Fourteen college aged students …

Cardiovascular Responses to Exercise: an Evaluation of the Effectiveness of a Brief Exposure to CPAP in Obstructive Sleep Apnea Patients
… of a single night of CPAP titration on various cardiovascular, gas exchange, and perceptual measures, we conducted submaximal ramping exercise tests to an intensity of ~75% of the heart rate reserve in five male subjects. Means and standard deviation for their age and BMI were 57.0±14.7 years …

Acute and Chronic Effects of Low Versus High Glycemic Index Carbohydrate Sources on Metabolic and Cardiovascular Responses in Lean and Obese Dogs
… diseases, including obesity, diabetes and cardiovascular disease. Health claims for dog food are not regulated in Canada, thus many claims do not have a scientific basis. The development of a pet food with proven health benefits is important to pet owners as well as the pet food industry. …

Cardiovascular responses to sustained isometric force production of the finger flexor and knee extensor muscle groups in weight-trained and untrained young men
… of this study was to investigate whether the cardiovascular responses to isometric force production differed significantly between weight-trained and untrained men. Thus, the cardiovascular responses to sustained isometric force production were investigated in 17 weight-trained (age = 23.5 …

Cardiovascular adjustments to isometric contractions: The role of intensity of contraction, endurance time, and different muscle groups
… time, and the contracting muscle group on the cardiovascular responses to static exercise. Three primary questions were addressed: (1) Are the cardiovascular responses to isometric contractions dependent on the relative intensity of contraction?; (2) Are the cardiovascular responses to …

THE EFFECTS OF GASTRIC AND HOMEOSTATIC AUTONOMIC AFFERENT REFLEXES ON CARDIAC AUTONOMIC EFFERENT ACTIVITY IN HEALTHY HUMAN VOLUNTEERS
… of gastric autonomic afferent reflexes on cardiovascular autonomic efferent activity are regarded as a direct neural effect of the activation of gastric receptors which send afferent inputs to the central nervous system (CNS) to cause various cardiovascular changes (Van Orshoven et al., …
