SÃO PAULO — A groundbreaking study published in Frontiers in Psychiatry suggests that the key to managing panic disorder may lie in the very physical sensations patients fear most. Researchers at the University of São Paulo Medical School found that brief bouts of high-intensity interval exercise—specifically short sprints—reduced the severity of panic disorder (PD) symptoms significantly more than traditional relaxation therapy.
The randomized trial, led by Ricardo William Muotri, PhD, followed 72 sedentary adults over 12 weeks. The results were striking: those who engaged in the sprinting program experienced fewer and less intense panic attacks, lower levels of depression, and, perhaps most surprisingly, reported higher levels of enjoyment and engagement than those in the relaxation group.
Flipping the Script on Panic
Panic disorder affects approximately 5% of U.S. adults over their lifetime. It is characterized by sudden, overwhelming waves of fear accompanied by physical symptoms like a racing heart, shortness of breath, and dizziness.
Traditionally, clinicians use Cognitive Behavioral Therapy (CBT) as the gold-standard treatment. A vital component of CBT is “interoceptive exposure”—deliberately inducing these scary physical sensations in a controlled environment (such as spinning in a chair to induce dizziness) to teach the brain that these signals are not dangerous.
However, many patients find these clinical exercises aversive or difficult to stick with. Dr. Muotri’s team hypothesized that exercise could serve as a “natural” form of this exposure.
“Healthcare professionals can adopt brief intermittent intense exercise as a natural and low-cost interoceptive exposure strategy,” Dr. Muotri stated in a news release. “It doesn’t need to take place in a clinical setting, so that exposure to the symptoms of a panic attack is brought closer to the patient’s daily life.”
The Study: Sprints vs. Stillness
The researchers recruited 72 adults with a primary diagnosis of panic disorder who were previously sedentary. The participants were split into two groups:
-
The Exercise Group: Performed three sessions a week consisting of a 5-minute warm-up, a 15-minute walk, a 30-second high-intensity sprint, and a final 15-minute walk. Over 12 weeks, the number of sprints gradually increased to six per session.
-
The Relaxation Group: Completed three weekly 45-minute sessions of Jacobson Progressive Muscular Relaxation, which involves systematically tensing and releasing various muscle groups combined with deep breathing.
To ensure a fair comparison, all patients received a placebo pill, and the assessing psychiatrists were “blinded,” meaning they did not know which treatment the patient had received.
The Findings
By the end of the 12-week intervention, the exercise group showed superior improvements across nearly every metric:
-
Severity Scores: Using the Panic Agoraphobia Scale (PAS), the exercise group’s score dropped to 14.9, compared to 23.1 in the relaxation group.
-
Long-term Success: At a 24-week follow-up (three months after the supervised sessions ended), the gap widened. The exercise group maintained a score of 14.2, while the relaxation group rose to 24.7.
-
Depressive Symptoms: Exercise also proved more effective at lifting mood, with significantly lower depression scores at the six-month mark.
Why High-Intensity?
The power of the sprint lies in its ability to mimic a panic attack. When a person sprints, their heart rate skyrockets and their breathing becomes labored—the exact physiological markers of panic. By experiencing these sensations through exercise, patients “retrain” their nervous system to recognize that a racing heart is a result of physical exertion, not an impending medical emergency.
“This is a fascinating application of exposure therapy,” says Sarah Jenkins, a clinical psychologist specializing in anxiety disorders who was not involved in the study. “For many patients, sitting in a doctor’s office blowing through a straw to feel breathless feels clinical and forced. Going for a run feels like reclaiming their body. It changes the narrative from ‘my body is failing me’ to ‘my body is strong.’”
Practical Implications for Patients
For those living with panic disorder, this research offers a low-cost, accessible tool. Unlike specialized therapy which can be expensive or hard to find, a “sprint-walk” protocol can be performed in a local park or on a sidewalk.
The high adherence rate in the study suggests that patients actually enjoyed the high-intensity sessions more than the relaxation exercises. This challenges the common assumption that people with anxiety should only engage in “calming” activities like yoga or meditation.
