Older veterans, many of whom have lived with PTSD symptoms for several decades, report a number of negative health outcomes. Despite the demonstrated benefits of regular exercise on physical and psychological health, no studies have explored the impact of exercise in older veterans with PTSD. This paper describes the development, design, and implementation of the Warrior Wellness exercise pilot study for older veterans with PTSD. Veterans aged ≥60 with a Diagnostic and Statistical Manual of Mental Disorders (DSM-V) diagnosis of PTSD will be recruited and randomized to (a) Warrior Wellness, a 12-week supervised, facility-based exercise intervention, or (b) usual care for 12 weeks. Warrior Wellness is a theory- and evidence-based behavioral intervention that involves 3 sessions per week of multi-component exercise training that targets strength, endurance, balance, and flexibility. Warrior Wellness focuses on satisfaction with outcomes, self-efficacy, self-monitoring, and autonomy. Factors associated with program adherence, defined as the number of sessions attended during the 12 weeks, will be explored. Primary outcomes include PTSD symptoms and cardiovascular endurance, assessed at baseline and 12 weeks. Compared to those in usual care, it is hypothesized that those in the Warrior Wellness condition will improve on these efficacy outcomes. The Warrior Wellness study will provide evidence on whether a short-term exercise intervention is feasible, acceptable, and effective among older veterans with PTSD, and explore factors associated with program adherence.

These results have significant implications for workplace health and associated policies, because long-term trends in occupational data suggest that sedentary occupations have increased significantly in the United States between 1960 and 2008 (1). Self-reported levels of sitting in the United States average approximately 4.7 h·d (3); however, this estimate is likely conservative because individuals tend to underreport their sitting behavior. For example, a study among Australian adults using an objective assessment (inclinometer) reported an average of 8.8 h of sitting per day (4). Furthermore, objective data collected by accelerometry in the U.S. National Health and Nutrition Examination Survey indicate that children and adults spend approximately 7.7 h·d being sedentary (5). Thus, a large proportion of the U.S. population is exposed to excessive levels of sedentary behavior and is at increased health risk because of this exposure. A topic of interest that has been addressed in this arena is whether the observed associations of sedentary behavior and increased chronic disease and mortality risk are modified or moderated by physical activity (light, moderate, vigorous, or total). Studies typically statistically “adjust” for a measure of physical activity by including it in a statistical model as a covariate or by stratifying the analysis by level of physical activity (i.e., active vs inactive). Using this approach, Ekelund et al.
