The effect of an aerobic training program on cardiovascular reactivity to the cold pressor test
… diastolic blood pressure (DBP) reactivity to the cold pressor test ≥ 5 mm Hg were randomly assigned to either an intervention group or a control group. The intervention group was asked to participate in an aerobic exercise session 4 d/wk for 8 weeks, consisting of walking/jogging for 30 minutes at …

Financial Decision Making Under Stress
… to elicit participants risk preferences. The Cold Pressor Test was used to induce a safe level of stress. In the treatment group, 62% of participants are risk averse; versus 76% in the control group. Additionally, inconsistent financial decision making was observed in both groups: 55% of …

Tolerance to Lower Body Negative Pressure: Effects of Sex and Sufentanil
… Furthermore, following that LBNP challenge, to test the efficacy of sufentanil on pain ratings, each participant performed a cold pressor test. RESULTS: Females had a ~35% lower tolerance to LBNP compared to males (p=0.003), accompanied by a lower burst frequency (p=0.016). Sufentanil did not …

The effects of catastrophizing and labeling on pain tolerance, sensation, and affect
… condition. All participants then took part in a cold-pressor test. The cold-pressor measure of pain tolerance, as well as visual analog scales of sensory and affective ratings of pain, provided the dependent measures. Participants also completed the Anxiety Sensitivity Index (ASI) and the Somatic …

Effects of acute aerobic exercise on cardiovascular reactivity to stress in healthy, untrained males
… diastolic blood pressure (DBP) response to the cold pressor test (CPT), then randomly assigned to either a minimal exercise condition (5 min of freewheel cycling) or 30 min of exercise on a bicycle ergometer at 55-60% V02max. Heart rate (HR) and BP were monitored during the resting, arousal, and …

A Brief Mindfulness Intervention on Acute Pain Experience: An Examination of Individual Difference
… (Tashiro & Mortensen, 2006) to empirically test the immediate effect of a 15-minute mindfulness intervention on acute pain experience. The study employed a three-group, repeated measures experimental design with two active control conditions (sham mindfulness and attention control) and an …

Cardiovascular reactivity to stress in men: effects of masculine gender role stress appraisal and masculine performance challenge
… gender role stress (MGRS) was compared using the cold-pressor test under conditions of high and low masculine performance challenge. Under conditions of minimal challenge, it was predicted that high and low MGRS men would not differ on reactivity. Under high challenge, high MGRS men were expected …

The role of branding and pricing on health outcomes via the placebo response
… analgesic. A second laboratory study, using the cold pressor test and a medication with low non-placebo efficacy, failed to demonstrate superiority of a brand-name over generic medication in terms of cold tolerance or pain ratings, but the brand-name did lead to quicker habituation to the cold …

Moderating effect of a single aerobic exercise session on the cardiovascular response to a stressful procedure 45 minutes later
… pre-stressor anticipation period, and during the cold pressor test. stroke volume was measured with impedance cardiography and total peripheral resistance (TPR) was estimated. SBP was significantly lower during the second minute of the anticipation period (F [1,29] = 4.75, p = .04) forty-five …

Gender differences in cardiovascular reactivity: effects of the gender relevance of the stressor
… female college students (<u>N</u> = 95) to the cold-pressor test (CPT) was compared under masculine-relevant and gender-neutral stressor instructions during an anticipation phase, a stressor phase, and a recovery phase. Men were expected to show greater CVR than women to the masculine-relevant …

The role of the prefrontal cortex in hypnotic and placebo analgesia.
… 1939; 2008). Participants then completed the Cold Pressor Test (CPT), a commonly used test for pain-threshold (the time at which pain is first felt) and pain-tolerance (from pain threshold until hand removal), under three counterbalanced conditions: 1) After receiving a hypnotic suggestion for …

The effects of acute aerobic exercise on cardiovascular reactivity to stress in healthy, trained and untrained males
… and untrained individuals who performed the cold pressor test (CPT) after exercising for 30 minutes at 70% VO₂ max and participating in an attention control. Eighteen untrained and eleven trained males were randomly assigned to a treatment sequence. The subjects performed either 30 minutes of …

The effect of sedentary behaviour on cardiovascular biomarkers in active, healthy adults
… (via ultrasound) were recorded during the cold pressor test (CPT). During visit two, cardiorespiratory fitness (CRF; VO2peak) was assessed using the modified Bruce protocol. Physical activity (PA) and SB was objectively measured for seven days via accelerometry and inclinometry …

Examining endothelial function in humans in vivo: improving guidelines and exploring novel measures
… following sympathetic stimulation (e.g. after a cold pressor test, CPT). The carotid artery appears to mirror coronary responses to CPT, as it shows dilation in healthy participants, whilst those at risk demonstrate a constriction. In this thesis, we sought to understand the relation of CAR with …

Investigating the neuroendocrine and hemodynamic responses to physical and psychological stress tasks and their effects on endothelial-dependent flow mediated vasodilation using a sustained stimulus
… responses between the Trier Social Stress Test (TSST) and 5min cold pressor test with and without social evaluation (CPT, CPT+SE) and 2) to examine the impact of these stressors and cortisol elevation on EX-FMD. 59 healthy male subjects were randomly assigned to one of three conditions: …

The influence of a single session of aerobic exercise on blood pressure during daily activities
… those subjects with a greater reactivity to the cold pressor task would show a larger reduction than all subjects in mean BP. A secondary hypothesis was that there would be an attenuation of cardiovascular reactivity (CVR) following exercise. Fifteen college aged students enrolled in health …
