Clinical Trial Summary

The purpose of this research study is to examine the effect of various forms of exercise training on blood vessel function in healthy individuals as well as individuals with mental health disorders (posttraumatic stress disorder (PTSD) and/or generalized anxiety disorder (GAD)).

Description:

Study #2 is made up of five sessions done on five separate days and the entire study can be completed in as little as 14 weeks. All testing sessions will take place at the Exercise Physiology Research Laboratory. Volunteers will be asked to participate in one initial testing session (Visit 1) lasting < 1 hour that will help make them more familiar with the study equipment and procedures, determine body measures (height, weight, body fat), determine the maximum strength of their forearm and calf, and require one blood draw. The following two testing sessions (Visits 2 and 3) with each session lasting between 2-3 hours that will involve multiple tests designed to determine the health of their blood vessels. For Visit #2 they will be randomly given either antioxidant pills or placebo pills to determine the effect of oxidants on blood vessel health. For Visit #3, they will be given whatever set of pills (antioxidant or placebo) that they did not receive during Visit #2. also include two additional testing days (Visits 5 and 6) that are identical to Visits #2 and #3, two visits to test endurance or strength prior to and after the exercise training (Visit 4 and 7), and ten weeks of exercise training (done 3-5 days per week). The exercise training will include one of three treadmill running programs that differ by exercise intensity and/or exercise frequency.
