About this trial
Volunteers for the study are asked to participate in two laboratory sessions. In the first laboratory session, volunteers are asked to provide a blood sample which will be used to measure factors related to health. Participants also complete questionnaires related to demographic and health-related information and undergo evaluations of their body composition. In the second laboratory visit, participants are asked to have cardiovascular, neuroendocrine, and inflammatory activity measured during a brief period of rest and during a short challenging psychological task. Participants will also complete questionnaires. The study is designed to examine the associations between experiences such as trauma and resiliency with changes in bodily systems during a challenge and current health.
