The influence of social support on cardiovascular responses during stressor anticipation and active coping.

This study investigated effects of different types of social support on cardiovascular reactivity during anticipation of, performance of and recovery from an evaluative speaking task. Thirty male and 30 female students were assigned to one of three social conditions: alone, mental activation of supportive ties, actual support transactions. Cardiovascular effects of social support were found to differ over task conditions and they were not unidirectional. During passive stressor anticipation, support conditions attenuated SBP reactivity, in particular mental activation of supportive ties. During active speech performance gender-specific support effects were observed. The alone condition elicited higher SBP reactivity in men compared to women, support conditions enhanced SBP reactivity in women and attenuated SBP reactivity in men resulting in comparable cardiovascular activation across gender groups. Drawing from research on active coping and energization gender-specific cardiovascular activation was attributed to differences in effort expenditure.
