The Summary
This randomized controlled trial evaluated the effects of eight weeks of moderate-intensity aerobic exercise versus resistance training in 56 female university students with premenstrual syndrome (PMS). Researchers used functional near-infrared spectroscopy (fNIRS) to track prefrontal brain activity alongside assessments for anxiety and emotional inhibition. Both exercise groups showed significant reductions in anxiety scores and improved reaction times during emotional tasks compared to the control group. However, resistance training led to greater anxiety reduction and increased activation in the left dorsolateral prefrontal cortex, highlighting its unique neurological benefits.
Why this is interesting
While cardio is traditionally recommended for managing PMS symptoms, this study suggests resistance training is actually more effective for relieving premenstrual anxiety. By using fNIRS imaging, researchers demonstrated that lifting weights directly boosts activation in the prefrontal cortex—the brain region responsible for emotional regulation. For women seeking natural relief from monthly mood swings, swapping some cardio sessions for strength work could offer a powerful, targeted way to calm the nervous system and reclaim emotional control.
