“…Only those women who completed 40 min of exercise showed lower mean arterial pressure reactivity when compared to attentional controls. This eþ ect has also been demonstrated in untrained women (Rejeski et al, 1992) and sedentary males (Ebbesen et al, 1992;Steptoe et al, 1993). It is clear, therefore, that people who complete a relatively high dose of aerobic exercise will experience lower reactivity to subsequent psychological stress.…”

This study was designed to assess the effect of performance feedback on stress reactivity after recovery from maximal exercise. Forty competitive athletes were recruited to complete a maximal exercise test. Performance feedback was manipulated after the exercise test to give four groups: (1) high performance, (2) low performance, (3) accurate feedback and (4) no exercise control. Cardiovascular reactivity was assessed during psychological stress. The results indicate that accurate feedback participants experienced lower relative reactivity to stress (lower mean arterial pressure) than their no-exercise counterparts. These results demonstrate that the stress-buffering effect of exercise extends to maximal exercise. In addition, high-performance participants experienced lower relative reactivity than low-performance participants. Thus, low-performance feedback was sufficient to remove the buffering effect of exercise. There were no differences between the high-performance and accurate feedback conditions, or between the low-performance and control conditions.

“…Comedication was one of the exclusion criteria. Moderate aerobic exercise has been shown to attenuate the response to a CPT [44]; however, all subjects were advised to abstain from more than moderate walking to the laboratory on the morning of the study.…”

In some patients with type 1 diabetes, various physiologic reactions during a cold pressor test (CPT) are impaired. Whether this is caused by diabetic autonomic neuropathy, disturbed secretion of catecholamines, or disturbed blood glucose control is unknown. The authors, therefore, performed CPTs in patients with type 1 diabetes and in control subjects. They measured blood glucose concentrations, insulin concentrations, cardiac autonomic reflexes, and (before and after the CPT) venous catecholamine concentrations and analyzed correlations between these variables. Twenty-two patients with type 1 diabetes (17 men, 5 women; mean age +/- SD, 26.6 +/- 6.5 y; diabetes duration, 7.6 +/- 0.7 y; glycosylated hemoglobin concentration, 7.7 +/- 2.4%) and 35 control subjects with comparable age and gender distributions were studied. Venous catecholamines were measured before and at the end of a 5-minute CPT. In patients with diabetes, only noradrenaline concentrations increased during the CPT, whereas adrenaline concentrations that were already increased at rest did not change. Adrenaline concentrations correlated inversely with insulin concentrations. In control subjects, both adrenaline and noradrenaline increased significantly during the CPT. In both groups, the magnitude of the individual change in catecholamine concentrations was inversely correlated with the respective resting concentration. Changes in catecholamines, cardiovascular reflex tests, and blood glucose concentrations did not correlate with blood pressure changes. The authors conclude that, in patients with diabetes, resting adrenaline concentrations are related to insulin concentrations. Contrary to control subjects, in patients with diabetes, only noradrenaline increased during CPTs. In both groups, changes in catecholamine concentrations after the CPT were inversely related to the respective resting concentrations.

“…Few studies have been conducted to elucidate mechanisms associated with the acute reduction in BP reactivity after exercise. In this regard, Brownley et al12 suggested that reduced BP reactivity to MS after an aerobic exercise session is associated with a decrease in sympathetic drive, whereas Ebbesen et al18 observed the maintenance of catecholamine levels in response to MS. The mechanisms underlying attenuated BP responses to MS following a single bout of exercise require further exploration.…”

PurposeThis study aimed to investigate the effects of resistance exercise (RE) on autonomic control and blood pressure (BP) reactivity during mental stress (MS) in treated older hypertensive women.MethodsTen older hypertensive women (age =71.1±5.5 years; body mass index =24.2±3.9; mean BP [MBP] =85.4±3.5) underwent a protocol consisting of BP and heart rate variability (HRV) output assessments at baseline and during MS, and these measurements were taken before and 60 minutes after two bouts of RE (traditional and circuit). MS was induced through a computerized 3-minute Stroop color–word test before and 1 hour after each exercise session; BP was measured every minute during MS, and HRV was monitored as a measure of cardiac autonomic control.ResultsA significant effect of time on systolic BP (Δpre =17.4±12.8 versus Δpost =12.5±9.6; P=0.01), diastolic BP (Δpre =13.7±7.1 versus Δpost =8.8±4.5; P=0.01), and MBP (Δpre =14.0±7.7 versus Δpost =9.3±5.4; P<0.01) after RE was observed, with no differences between the two sessions. In addition, a significant effect of time on log-normalized low-frequency component of HRV (ms2; 5.3±0.8 pre-exercise MS versus 4.8±1.0 baseline value; P=0.023) was also observed, showing a significant change from baseline to MS before RE, but not after RE sessions. These results may be related to a lessened RE-mediated cardiac sympathetic activity during MS.ConclusionRE is an effective tool to reduce BP reactivity to MS, which could therefore be associated with an acute reduction in cardiovascular risk. This result presents relevant clinical implications, combining previous evidence that recommends this exercise modality as an important component of an exercise program designed for the older and hypertensive subjects.
