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 …

Single Nucleotide Polymorphisms of the ATP1a2 gene and Their Effects on Blood Pressure and Other Cardiovascular Variable in African Americans and Caucasian Americans
… and Their Effects on Blood Pressure and Other Cardiovascular Variables in African Americans and Caucasian Americans. Doctor of Philosophy (Integrative Physiology), May 2007. Mutations in the 3’ – untranslated region (3’-UTR) of the ATP1a2 gene, which encodes the α2 subunit of Na+-K+-ATPases are …

The psychophysiology of risk processing and decision making at a regional stock exchange
… in mean skin conductance response and cardiovascular variables during transient market events relative to no-market-event control intervals. In addition, I find a strong relationship between trading decisions and physiological responses. Using regression, I demonstrate that heart rate …

Muscle Metaboreflex And Arterial Baroreflex: Action, Interaction And Altered Control In Heart Failure
… investigated however in heart failure, most cardiovascular variables exhibit occlusive interaction. Preferential vasoconstriction of non-ischemic vasculature redirects cardiac output and increases hindlimb blood flow in normal animals but this increase is significantly attenuated in heart …

Cardiovascular Effects and Enjoyment of Exer-Gaming in Older Adults
… not been well studied. Purpose: To quantify the cardiovascular responses, the enjoyment, and the untoward physical discomforts to a 15 minute trial of EG (Nintendo Wii Tennis) in healthy, older adults. Methods: A quasi-experimental design using a convenience sample of 34 self-reported healthy …

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 …

Simple Tests for Assessing Kidney and Cardiovascular Function in Chromic Kidney Disease Patients (Stages 2, 3 and 4)
… of risk factors for progression of CKD linked to cardiovascular disease (CVD) remains difficult, particularly in older subjects. To address this GFR and the cardiovascular parameters arterial stiffness, heart rate variability (HRV) and natriuretic peptides (NT- proBNP and NT-proCNP) were measured …

Hemodynamic Responses to Isometric Contractions of the Finger Flexor and Leg Extensor Muscle Groups in Men 18-30 and 50-70 Years of Age
… tests. The object was to ascertain which cardiovascular variables(s), heart rate, stroke volume, cardiac output, total peripheral resistance, systolic blood pressure, diastolic blood pressure, pulse pressure, and mean arterial pressure demonstrated significantly different responses to …

The Influence of Aging on Cardiovascular Measures After an Acute Bout of Resistance Exercise
… how aging affected arterial stiffness and other cardiovascular measure responses to a whole body resistance training session. Methods: Thirty-six men were separated into three groups based on age (Young-aged, YG: 20-39 years; middle-aged, MG: 40-59 years; older-aged, OG: 60-75 years). A …

EFFECTS OF ACUTE NORMOBARIC HYPOXIA DURING EXERCISE AND CONCURRENT MENTAL STRESS ON THE CARDIOVASCULAR SYSTEM IN HEALTHY ATHLETES
… as physiological stressors that challenge cardiovascular homeostasis through mechanisms orchestrated by medullary cardiovascular control centers. During physical exertion, the activation of the “exercise pressor reflex” facilitates systemic adjustments to preserve perfusion of vital organs …

Clarifying the Nature of Pain-Related Anxiety: Implications for Assessment and Treatment of Chronic Musculoskeletal Pain
… during, and post-experimental tasks included (a) cardiovascular variables to provide indices of anxious arousal; (b) self-report measures of pain-related anxiety, social evaluative anxiety, and general negative affectivity; and (c) behavioural performance measures (i.e., correct answers on the …

Central autonomic control in spontaneously hypertensive rats: a study on phasic phenomena during rapid-eye-movement sleep
The cardiovascular regulation undergoes wide changes in the different states of sleepwake cycle. In particular, the relationship between spontaneous fluctuations in heart period and arterial pressure clearly shows differences between the two sleep states. In non rapid-eye-movement sleep, heart …

Sleep/wakefulness versus urethane anesthesia: analogous arousal states for respiratory control?
… patterns, at least in terms of respiratory and cardiovascular function. Therefore, the first objective of this study was to examine the effects of sleep state on respiratory and cardiovascular variables, and to compare these effects to those observed during superficially similar arousal states …

Comparing glutathione peroxidase and glutathione reductase activity and their associations with cardiovascular measures in Africans and Caucasians : the SABPA study
… may contribute to the changing prevalence of cardiovascular disease (CVD) occurring amongst urbanized Black Africans. Changes in eating patterns and exposure to increased levels of oxidants may play a role. Accumulative amounts of data indicate the role that oxidative stress may play in the …
