“…It appears that the higher the resting value of blood pressure, the greater the rise in blood pressure. So the increase in blood pressure in hypertensive individuals when they are talking is greater than that in normotensive individuals (Lynch et al, 1981). The extent of the reaction appears to be comparable with that of a regular exercise stress test (Thomas et al, 1992), does not change as a result of the use of antihypertensives (Dimsdale et al, 1992) and occurs both in an experimental and a medical setting (Lynch et al, 1982).…”

“…The physical act of talking has been shown to raise blood pressure (9). However, subsequent research has shown that speaking about a topic of personal relevance results in greater increases in blood pressure and greater decreases in T-wave amplitude and blood volume pulse than does producing neutral speech (10).…”

The purpose of this study was to examine the effects of a 2-hour laboratory challenge on heart rate, blood pressure, catecholamines, and cortisol; and investigate the contribution of the physical act of speaking on both neuroendocrine and cardiovascular measures. Using a within-subjects design, 14 subjects were tested individually during two separate laboratory sessions. During one session, subjects engaged in two cognitively demanding tasks for 2 hours. During the other session, subjects executed the verbal demands of the tasks for 2 hours, but cognitive demands were absent. During both sessions, blood pressure and heart rate were measured and arterialized blood samples were obtained for the measurement of epinephrine, norepinephrine, and cortisol. Subjects demonstrated significantly greater increases in systolic blood pressure, diastolic blood pressure, heart rate, epinephrine, and cortisol during the cognitively challenging session than during the control session. It is concluded that sustained elevations in cardiovascular and neuroendocrine measures can be achieved in the laboratory, and that the effects of such tasks cannot be attributed solely to the physical demands of speaking. Implications for the measurement of circulating catecholamines and cortisol during laboratory studies are discussed.

“…The state of physical inactivity and the absence of orthostatic loading associated with HDT bedrest was expected to cause an immediate attenuation of the circadian BP variability. The residual day±night variation of BP can be explained by other sources of BP variability still present when con®ned to bed, such as mental stress (James et al 1986), talking (Lynch et al 1981), micturition and defecation (Littler et al 1974) and the effect of ingested food and drink (Kelbaek et al 1989). A striking rise of BP was observed during the meals in the HDT period, which were taken while lying with the face downward and the head protruding out of the bed.…”

Download date: 10 May 2018Circadian blood pressure and systemic haemodynamics during 42 days of 6°head-down tilt ABSTRACTHead-down tilted bedrest is a ground-based microgravity simulation model. Since in this position the influence of chief external determinants of circadian blood pressure variation, i.e. activity and posture, are reduced, it may reveal endogenous oscillatory factors. The effects of 42 days of 6°head-down tilt on the circadian profiles of continuous finger blood pressure, heart rate, stroke volume, cardiac output and total peripheral resistance were analysed. In seven healthy volunteers (25±31 years) twelve 22 h Portapres registrations were performed: two in an ambulatory baseline period, eight during 42 days of head-down tilt, and two during recovery. Stroke volume was estimated by a pulse contour method (`Modelflow') from the finger arterial blood pressure tracing. Head-down tilt rapidly reduced circadian BP variation, especially for diastolic blood pressure. No effect of long-term headdown tilt on blood pressure level was observed. The day-night difference in heart rate was essentially unaffected. Cardiac output was maintained through an increase of heart rate and simultaneous decline of stroke volume. Our observations confirm the overriding importance of physical activity and orthostatic load on the diurnal variation of BP. The time-frame of the changes in stroke volume and heart rate during head-down tilt might point to a contribution of other factors besides a r...
