“…There is a tendency for the heart rate in the elderly group to be lower than that of the young group at rest and dur ing isometric work. This supports the data in subjects up to the age of 65 years [Petrofsky, 1975] and in old men [Kino, 1975;Ordaway, 1979] but the reason for this reduction is uncertain.…”

“…The studies of the cardiovascular re sponses in the elderly to isometric exercise have been limited and marred by differences in technique [Kino, 1975;Ordaway, 1979]. The potential value of isometric exercise as a test of autonomic function has been ignored.…”

“…The haemodynamic effects of dynamic exercise and mental stress are mediated mainly by beta-adrenergic pathways acting on the heart and at least some betaadrenoceptor antagonists appear to modify these re sponses [Davidson et al, 1976;Floras et al, 1985], On the other hand, the sympathetic mechanism involved in the cardiovascular changes resulting from cold and isometric exercise is subserved predominantly by alpha-adreno ceptors in the peripheral arteriolar resistance vessels [Ew ing et al, 1973;Floras et al, 1985;Kino et al, 1975], In these circumstances, the influence of beta-adrenoceptor antagonism is less consistent [Floras et al, 1985;Harris et al, 1982] while there is some evidence that calcium antag onism may attenuate alpha-mediated responses [Harris et al, 1982;Van Zwieten et al, 1986].…”

The influences of verapamil, propranolol and their combination on blood pressure and heart rate during cold pressor testing and isometric exercise were examined in 13 patients with essential hypertension. Verapamil modified the peak pressor responses to each stimulus while the major action of propranolol was on heart rate. Together the drugs attenuated both haemodynamic responses. Combined calcium antagonism and beta-blockade may modify favourably surges in blood pressure and heart rate in ambulant hypertensives.

“…We employed a psychological stressor (speech preparation) and a physical stressor (sustained isometric handgrip), which have been shown previously to increase sympathetic and decrease parasympathetic cardiac activity Cacioppo et al, 1994;Kino, Lance, Shahamatpour, & Spodick, 1975;Pollack & Obrist, 1988;Saab, Matthews, Stoney, & McDonald, 1989 Lewis, Leighton, Forester, & Weissler, 1974;Sherwood et al, 1990). Higher values of RSA indicate a greater parasympathetically mediated variation in heart period that coincides with inspiration and expiration after controlling for significant respiratory adjustments (Berntson, Cacioppo, & Quigley, 1993b;Berntson et al, 1997;Grossman, Karemaker, Wieling, 1991;Porges & Bohrer, 1990).…”

Gastric myoelectrical and autonomic cardiac reactivity to laboratory stressors

We evaluated the effects of two laboratory stressors (speech preparation and isometric handgrip) on gastric myoelectrical and autonomic cardiac activity, and the extent to which autonomic responses to these stressors and somatization predict reports of motion sickness during exposure to a rotating optokinetic drum. Both stressors prompted a decrease in preejection period (PEP) and respiratory sinus arrhythmia (RSA), and an increase in a dysrhythmic pattern of gastric myoelectrical activity, termed gastric tachyarrhythmia. Stressor-induced decreases in RSA and higher somatization scores predicted increased reports of motion sickness during drum rotation. These results demonstrate that laboratory stressors concurrently affect gastric myoelectrical activity and autonomic control of the heart, and that stressor-induced decreases in RSA and higher levels of somatization predict motion sickness susceptibility. DescriptorsElectrogastrography; Impedance cardiography; Motion sickness; Parasympathetic; Somatization; Stress; Sympathetic Individuals often report epigastric symptoms during stressful experiences (Stern & Higgins, 1969). These symptoms are reflected in such expressions as "a nervous stomach" and may range in severity from a simple awareness of gastric activity to a sensation that disrupts ongoing behavior. Although recent epidemiological findings indicate that there is an increased prevalence of gastrointestinal symptoms among individuals with affective disorders (Hochstrasser & Angst, 1996;Lydiard et al., 1994;Marten et al., 1993) and an increased prevalence of negative affect and stressful life events among individuals with functional gastrointestinal disorders (Bennett et al., 1997;Bennett, Tennant, Piesse, Badcock, & Kellow, 1998;Whitehead, , 1996Whitehead, Crowell, Robinson, Heller, & Schuster, 1992), the effects of stressful experiences on the human stomach have been studied infrequently over the last several decades. One reason for the relative dearth of research on gastric reactivity to stress is that most gastrointestinal measurement procedures are invasive.Address reprint requests to: Peter J.

More recently, gastric intubation and intraluminal pressure recording techniques have been used to show that stressors such as electr...
