The influence of music on physiological and affective exercise responses was studied in 8 trained and 8 untrained runners under three music conditions ("no", "sedative", and "fast") during low, moderate, and high intensity exercise. Repeated measures ANOVA revealed increased respiratory frequency (FR) during fast music as compared to the no music and(More)
The neuropeptide oxytocin (OT) enhances maternal behavior and decreases blood pressure (BP) and stress responses in animals. Thus, the relationship of OT responsivity to BP in 14 breast- and 11 bottle-feeding mothers of infants was examined. Laboratory BP was assessed during baseline, speech preparation, active speech, and recovery on 2 days, 1 in which(More)
The effects of hostility and social support on clinic, work, and home systolic (SBP) and diastolic (DBP) blood pressures were evaluated in 129 healthy adults. High hostility was related to higher SBP and DBP in Whites; low hostility was related to higher SBP and DBP in Blacks. These relationships were significant for men at home and at work and for women at(More)
In this study, we examined test-retest stability of cardiovascular stress responses over a decade of the life span. Participants were 55 male college undergraduates, 19 years of age at initial testing, and 29 years of age at follow-up testing. Stressors were a foot cold pressor and an aversive reaction time task. Cardiovascular measures included systolic(More)
The typical American diet includes high salt and low potassium, a pattern linked to elevated blood pressure (BP) in cross-cultural studies. This study compared resting and stress cardiovascular responses on a high salt, low potassium diet to those observed during 2 interventions: salt restriction and potassium supplementation. Forty-seven percent of the(More)
