What is the purpose of this trial?

This trial explores how exercise might aid learning and memory in people with PTSD (Post-Traumatic Stress Disorder). Participants will engage in either moderate or low-intensity exercise after imagining a traumatic event, while researchers monitor their brain activity. The goal is to determine if exercise can enhance the processing of traumatic memories. Ideal candidates are those with PTSD from interpersonal violence. As an unphased trial, this study provides a unique opportunity to contribute to understanding how exercise can support PTSD recovery.

Will I have to stop taking my current medications?

The trial requires that you do not have recent changes in psychiatric medication within the past 4 weeks, and you must be able to abstain from daily benzodiazepine or stimulant use during study sessions.

Is there any evidence suggesting that this trial's treatments are likely to be safe?

Research has shown that exercise, whether moderate or low intensity, is generally safe for people with PTSD. Studies have found that moderate exercise can reduce PTSD symptoms, ease depression, and improve sleep. Those who engage in this type of exercise often feel better overall.

Low-intensity exercise also benefits individuals with PTSD by reducing stress and boosting mood. This type of exercise typically doesn't cause major side effects, making it a safe choice for many.

In summary, both moderate and low-intensity exercises are well-tolerated and help with PTSD symptoms without major negative effects. ^{1 2 3 4 5}

Why are researchers excited about this trial?

Researchers are excited about exploring exercise for treating PTSD because it's a non-invasive and accessible option that could complement or even reduce the need for medications and traditional therapy. Unlike standard treatments like cognitive-behavioral therapy or medications such as SSRIs, which focus on psychological or chemical pathways, exercise introduces a physical intervention that can influence both body and mind. Moderate-intensity exercise, in particular, has the potential to enhance brain function and emotional regulation through increased blood flow and neuroplasticity. Meanwhile, low-intensity exercise offers a gentler approach that might appeal to those unable to engage in more strenuous activities. By comparing these exercise regimens, researchers aim to uncover how physical activity can directly affect PTSD symptoms, offering a holistic alternative to existing treatments.

What evidence suggests that this trial's exercise treatments could be effective for PTSD?

Research shows that exercise can help people with PTSD (post-traumatic stress disorder). In this trial, participants will follow different exercise regimens. Studies have found that moderate exercise, which participants in one arm of this trial will perform, can reduce PTSD symptoms, lower anxiety, and improve sleep. This type of exercise can also lessen feelings of distress. Participants in another arm will engage in low-intensity exercise, which can also reduce PTSD symptoms, though it might not be as effective as more intense exercise. Both exercise types are linked to better mental health for people with PTSD. While high-intensity exercise might have stronger effects, moderate and low-intensity exercises still provide clear benefits for managing PTSD symptoms. ^{2 5 6 7 8}

What Are the Treatments Tested in This Trial?

Interventions

• Low Intensity Exercise
• Moderate Intensity Exercise

Trial Overview

Participants will be exposed to traumatic memories, then do either moderate or low intensity exercise. Their brain activity is monitored via MRI before and after the exercises.

How Is the Trial Designed?

Group I: Moderate Intensity Exercise Experimental Treatment 1 Intervention

Visit 1: Participants will complete study screening, PTSD assessments, and provide written narrative for a traumatic event and a neutral control event. Visit 2: Participants will complete baseline structural MRI scans before completing 8 trials of imaginal exposure - 4 neutral then 4 trauma narratives - with psychophysiological and fMRI measurement. Following completion of the imaginal exposure task, the participant will perform Moderate-Intensity Exercise (30-min at 70-75% max HR with 5-min warm-up and 5-min cool-down at 40-50% max HR), on a stationary bike. Visit 3: Participants will complete the same imaginal exposure with measurement of psychophysiology, fMRI, and subjective emotional responding.

Group II: Low Intensity Exercise Active Control 1 Intervention

Visit 1: Participants will complete study screening, PTSD assessments, and provide written narrative for a traumatic event and a neutral control event. Visit 2: Participants will complete baseline structural MRI scans before completing 8 trials of imaginal exposure - 4 neutral then 4 trauma narratives - with psychophysiological and fMRI measurement. Following completion of the imaginal exposure task, the participant will perform Low-Intensity Exercise (control; 40-mins at 40-50% max HR),on a stationary bike. Visit 3: Participants will complete the same imaginal exposure with measurement of psychophysiology, fMRI, and subjective emotional responding.

Published Research Related to This Trial

A review of 19 studies suggests that aerobic exercise can effectively reduce PTSD symptoms, either on its own or alongside standard treatments.

Potential mechanisms for this improvement include helping individuals cope with internal stress cues, enhancing brain function, promoting neuroplasticity, normalizing stress hormone levels, and lowering inflammation.

The Warrior Wellness pilot study aims to assess the feasibility and effectiveness of a 12-week exercise program for older veterans (aged 60 and above) with PTSD, focusing on improving PTSD symptoms and cardiovascular endurance.

This study will provide insights into how regular exercise can impact the health of older veterans with PTSD, potentially leading to better treatment options and improved quality of life.

Aerobic exercise may serve as a beneficial addition to traditional PTSD treatments, like exposure therapy, by improving both physical health and enhancing the effectiveness of fear extinction learning, which is crucial for reducing anxiety symptoms.

The review highlights emerging evidence from preclinical and clinical studies that suggest exercise can improve the consolidation and recall of fear extinction memories, indicating a potential new approach to treating PTSD more effectively.

Physical activity (PA) is an effective adjunct therapy for reducing PTSD symptoms, particularly in individuals with subsyndromal symptoms or those resistant to standard treatments, as highlighted by the review of existing literature.

There is a need for further research to determine the most effective types, doses, and durations of exercise for PTSD treatment, as findings from observational and controlled studies have been inconsistent.

A pilot trial involving 54 veterans aged 60 and older with PTSD showed that supervised exercise training is safe and well-accepted, with high adherence rates of 82% and minimal attrition of 14%.

Participants experienced clinically significant improvements in PTSD symptoms and related conditions after 12 weeks of exercise, suggesting that exercise could be an effective intervention for older adults with PTSD.

A two-week aerobic exercise program involving 33 participants with PTSD led to clinically significant reductions in PTSD severity for 89% of the participants, indicating that aerobic exercise can be an effective treatment for PTSD symptoms.

While all exercise groups experienced reduced PTSD symptoms, those focusing on their bodily sensations during exercise showed less improvement compared to those who were distracted or had no specific focus, suggesting that distraction may enhance the therapeutic effects of exercise.
