“…Our stress task was also unsurprisingly associated with increases in SBP and DBP, as well as decreases in TPR and reduced RMSSD HRV. The 8-minute PASAT has previously been shown to elicit a decrease in TPR (Ring, et al, 1999), although with longer exposure, there is an eventual increase in TPR (Ring, Burns, & Carroll, 2002). Similarly, we have previously demonstrated a decrease in RMSSD HRV to the 8-minute PASAT (Ring, et al, 1999) as have others using different stress tasks (e.g., Sloan et al, 1991).…”

The study aimed to: confirm that acute stress elicits metabolically exaggerated increases in cardiac activity; test whether individuals with elevated resting blood pressure show more exaggerated cardiac reactions to stress than those who are clearly normotensive; and explore the underlying mechanisms. Cardiovascular activity and oxygen consumption were measured pre-, during, and post- mental stress, and during graded submaximal cycling exercise in 11 young men with moderately elevated resting blood pressure and 11 normotensives. Stress provoked increases in cardiac output that were much greater than would be expected from contemporary levels of oxygen consumption. Exaggerated cardiac reactions were larger in the relatively elevated blood pressure group. They also had greater reductions in total peripheral resistance, but not heart rate variability, implying that their more exaggerated cardiac reactions reflected greater β-adrenergic activation

Background: Exaggerated cardiovascular reactions to psychological stress are considered a risk factor for cardiovascular morbidity. Social support may reduce such risk by attenuating cardiovascular reactivity to stress. Purpose: To examine the effects of three independent social support variables and their interaction on cardiovascular reactivity to acute stress. The variables were stranger or friend presence; active supportive or passive presence, and male or female presence. Methods: Cardiovascular reactions to mental arithmetic stress were measured in 112 healthy young women tested in one of eight distinct independent conditions: active supportive male friend; active supportive female friend, passive male friend; passive female friend; active supportive male stranger; active supportive female stranger, passive male stranger; and passive female stranger. Results:Support from a friend rather than a stranger was associated with attenuated blood pressure reactivity, but only when the supporter was a male friend. Support from a male stranger or female friend was associated with augmented blood pressure reactivity.Conclusions: This interaction between the intimacy and sex of the supporter on cardiovascular reactivity extends the findings of previous laboratory studies of social support and can, to an extent, be interpreted in terms of Social Comparison Theory.

“…Although human research has repeatedly acclaimed the use of salivary sIgA as a noninvasive marker of stress, particularly psychological acute stress [11][12][13][15][16][17][18], veterinary work in this field is at a standstill. The current unavailability of canine sIgA reference values is an underlying drawback to objective assessment of the potential usefulness of salivary sIgA as a noninvasive marker of stress in dogs.…”

ABSTRACT. The normal concentrations of salivary secretory IgA (sIgA) were examined, and the response of sIgA to acute stress was evaluated in dogs. Ten clinically healthy beagle dogs familiarized with the method of saliva sampling were used. During the non-stress period, saliva samples were collected between 0800 hr and 1700 hr at 1-hr intervals for 7 consecutive days and analyzed for sIgA concentration. After a 1-day control period, a noise stressor was presented for 15 min between 0845 hr and 0900 hr on 2 consecutive days. Saliva was collected at pre-stress, immediately after, 30 min after and 60 min after the stress. The average sIgA concentration over the 2-day period was compared with the control value. Environmental stimuli were restricted. During the non-stress period, significant variations were observed during the diurnal pattern, in which sIgA increased in the morning and then decreased; and the day-to-day variations were significant except at 0800 hr and 0900 hr. During the stress experiments, the sIgA concentration decreased significantly, immediately after and 30 min after the noise stress, and then increased to the same level as the control value by 60 min after the stress. When estimating the effectiveness of salivary sIgA as a marker of stress in dogs, the appropriate time for saliva sampling appears to be in the morning. Salivary sIgA was deemed potentially useful as a marker of stress in dogs.
