The current project aims to design and implement an 8-week Virtual Reality Adventure Therapy Exergaming (V-RATE) intervention focused on women veterans. A randomized controlled trial using a repeated measure design with a 1-month follow-up assessment will be employed to examine effects on physical and mental health outcomes.
The current project aims to design and implement an 8-week Virtual Reality Adventure Therapy Exergaming (V-RATE) intervention focused on veterans. A randomized controlled trial using a repeated measure design with a 1-month follow-up assessment will be employed. The project addresses two specific aims:
Aim 1. To examine the effects of an 8-week V-RATE intervention on physical health (i.e., BMI, physical activity, sedentary behavior) among veterans. We hypothesize that after controlling for socio-demographic variables and physical activity history, individuals in the V-RATE group would exhibit more improvement in the physical health indicators after the intervention compared to individuals in the control group. We further hypothesize gains would be maintained or enhanced at 1-month follow-up measure.
Aim 2. To examine the effects of an 8-week V-RATE intervention on mental health outcomes (i.e., depression, anxiety, posttraumatic stress, cognitive function, health-related quality of life), among veterans. We hypothesize that after controlling for socio-demographic variables and physical activity history, individuals in the V-RATE group will exhibit more improvement in the mental health indicators after the intervention compared to individuals in the control group. We further hypothesize gains maintained or enhanced at 1-month follow-up measure.

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| Intervention | Experimental | intervention participants will engage in a 30-minutes VR adventure games on a non-mobilized treadmill (5-min warm-up, 20-minutes treadmill, and 5-min cool-down) for a total of 6 sessions over 6-8 weeks. Participants in the V-RATE group will be instructed to self-pace walking/running on the treadmill while they are fully immersed in the VR games for two 10-minute bouts with a complete rest interval (heart rate reduces to normal range). Participants will complete measures at baseline, post-training, and one-month follow-up. |
|
| Control | No Intervention | Control participants will not receive the intervention. Participants will complete measures at baseline, post-training, and one-month follow-up. |

| Virtual Reality-based physical activity intervention | Device | The V-RATE intervention will be delivered through a 360-degree non-mobilized treadmill in a university clinical laboratory for 6-8-weeks (1-2 days/week, 30 minutes/session) totaling 6 sessions. The V-RATE program will be focused on creating a safe and immersive environment supportive of physical activity. The treadmill enables an individual can walk and run at self-paced speed, moving in 360-degrees (i.e., forwards, sideways, and backwards) without risk of falling. The core feature of the self-paced treadmill is a concave walking platform with an adjustable waist hardness that enables a safe, smooth, natural gait while adults with elevated BMI engage in an immersive walking and running motion. During the V-RATE intervention, participants will self-pace their locomotor action (walking/running/bending/ jumping) while they wear the VR headset and experience immersive VR adventure games using the Omniverse VR system. |
| Measure | Description | Time Frame |

| Measure | Description | Time Frame |
|---|---|---|
| Anxiety change from baseline to week 6-8 and one-month follow-up (Week 12) | Anxiety will be measured using the Beck Anxiety Inventory (BAI). | Baseline, post-training, Week 12 |
| Posttraumatic Stress change from baseline to week 8 and one-month follow-up (Week 12) |
