Walking or High Intensity Exercise for Anxiety

After an initial phone screen process, approximately 50 participants will be enrolled and evaluated/screened in person after consenting to achieve 30 eligible participants with a principal diagnosis of GAD, panic disorder, or social anxiety disorder and high anxiety sensitivity (Anxiety Sensitivity Index score =20). Participants will be given a choice of either high intensity interval training (HIIT) or walking interventions, which will be completed over the course of 8 weeks. The goal of the study is to 1) obtain pilot data comparing the efficacy of HIIT vs. walking for effects on psychiatric, functioning and immune outcomes, 2) to identify adherence levels given the choice of exercise intensity, and 3) to identify proportion of individuals opting for each intervention. Results from this pilot study will be used to inform future grant applications including a K award.
