老年人的个性特征和心肺健康状况是健康和长寿的可靠预测因素。我们研究了人格特征与休息时的能量消耗(基础代谢率)以及正常和最大持续步行时的能量消耗之间的关系。对来自巴尔的摩老龄化纵向研究的642名参与者的人格特征和氧气消耗进行了评估。结果表明，在正常步行速度下，人格特征与静息代谢率和能量消耗基本无关。然而，神经质得分较低(r = −为0.12)，而外向性(r = 为0.11)、开放性(r = 为0.13)和严谨性(r = 为0.09)得分较高的人，在高峰步行时的能量消耗显著较高。除了更好的有氧能力外，个性特征更有弹性的人走得更快，效率更高，因为他们每走一米所需的能量更少。性格和能量消耗之间的联系不受年龄或性别的影响，但部分原因是脂肪量的比例。总而言之，在需要心肺健康的更具挑战性的活动中，个性差异可能是最重要的。这些发现表明，人格与健康结果之间存在潜在的联系，比如肥胖和长寿。
Personality traits and cardiorespiratory fitness in older adults are reliable predictors of health and longevity. We examined the association between personality traits and energy expenditure at rest (basal metabolic rate) and during normal and maximal sustained walking. Personality traits and oxygen (VO2) consumption were assessed in 642 participants from the Baltimore Longitudinal Study of Aging. Results indicate that personality traits were mostly unrelated to resting metabolic rate and energy expenditure at normal walking pace. However, those who scored lower on neuroticism (r = −0.12) and higher on extraversion (r = 0.11), openness (r = 0.13), and conscientiousness (r = 0.09) had significantly higher energy expenditure at peak walking pace. In addition to greater aerobic capacity, individuals with a more resilient personality profile walked faster and were more efficient in that they required less energy per meter walked. The associations between personality and energy expenditure were not moderated by age or sex, but were in part explained by the proportion of fat mass. In conclusion, differences in personality may matter the most during more challenging activities that require cardiorespiratory fitness. These findings suggest potential pathways that link personality to health outcomes, such as obesity and longevity.
