Imagine facing sudden, overwhelming fear without any clear reason—this is the reality for many individuals experiencing panic attacks. Surprisingly, studies indicate that about 10% of people will encounter at least one panic attack in their lifetime. However, a smaller segment, between 2% and 3% of the population, suffers from panic disorder, characterized by frequent and severe panic attacks that significantly impair their daily functioning.
Traditionally, cognitive behavioral therapy (CBT) has been the go-to treatment for panic disorder, often complemented by antidepressant medication. One effective approach within CBT is known as 'interoceptive exposure.' This method involves therapists recreating common sensations associated with panic attacks—such as chest pain, rapid heartbeat, and heavy sweating—in a secure setting. The goal is to help patients learn that these sensations are not life-threatening, thereby increasing their tolerance to such symptoms.
Typically, interoceptive exposure includes controlled exercises like voluntary hyperventilation or spinning in a chair. However, new research suggests that incorporating a more dynamic and natural form of interoceptive exposure—brief periods of intense exercise—can yield better results. The findings of this study are detailed in the journal Frontiers in Psychiatry.
Dr. Ricardo William Muotri, a postdoctoral fellow at the University of São Paulo Medical School's Anxiety Disorders Program, emphasized, "Our research demonstrates that a 12-week regimen of brief, intense, intermittent exercise can effectively serve as an interoceptive exposure strategy for treating patients with panic disorder."
In this meticulously designed randomized controlled trial, Dr. Muotri and his team assessed the impact of brief, intense intermittent exercise compared to relaxation techniques commonly utilized in CBT. They involved a total of 102 adult participants diagnosed with panic disorder over a 12-week period.
The participants were evenly divided into two groups, each engaging in three sessions per week of their assigned exercise routine. Importantly, no medications were administered to either group throughout the trial.
The experimental group began each session with muscle stretching, followed by 15 minutes of walking, and then cycled through one to six 30-second bursts of high-intensity running paired with 4.5 minutes of active recovery. Each session concluded with another 15 minutes of walking. In contrast, the control group performed segmental muscle contraction exercises targeting various body regions, followed by localized muscle relaxation techniques. All participants wore biometric monitoring devices to track their physiological responses during these exercises.
The primary measure of success was the change in scores on the Panic and Agoraphobia Scale (PAS) over 24 weeks, which assesses the severity of panic symptoms based on responses to a questionnaire comprised of 13 items. Secondary measures included changes in anxiety and depression scores, as well as self-reported frequency and intensity of panic attacks. A psychiatrist, unaware of which treatment each participant received, evaluated these outcomes.
Results showed that while both groups experienced a decrease in PAS scores, anxiety, and depression levels, the improvements were significantly greater in the group engaging in brief, intense intermittent exercise. Moreover, participants in this group reported a larger reduction in both the frequency and severity of their panic attacks.
The authors concluded that brief, intense intermittent exercise represents a more effective interoceptive exposure method than traditional relaxation therapy for treating panic disorder, with benefits that persist for at least 24 weeks. Given that patients found this exercise approach more enjoyable than relaxation therapy, adherence to this treatment is likely to be higher.
"Healthcare providers can easily implement brief intermittent intense exercise as a natural, cost-effective interoceptive exposure method. This approach does not require a clinical environment, allowing patients to confront panic attack symptoms in their everyday lives. It could also be integrated into broader care models addressing anxiety and depressive disorders," Dr. Muotri summarized.
