Abstract
It has been argued that blunted cardiovascular and cortisol reactions to acute psychological stress reflect a dysregulation of the neural system that supports motivation. We examined the association between forced expiratory volume in 1?s, an effort (hence motivation) dependent measure of lung function measured by spirometry, and cardiovascular and cortisol reactions to a battery of standard psychological stress tasks, assessed 7 years later. Irrespective of how it was expressed, low forced expiratory volume was associated with blunted heart rate and cortisol stress reactivity. The association survived adjustment for smoking, a range of anthropometric and sociodemographic covariates, and commitment to the stress tasks, as well as cognitive ability
