Exercise Triggers Release of Powerful Brain-Boosting Protein, New Study Reveals
Regular physical exercise doesn’t just strengthen the body — it also triggers the release of a key brain-boosting protein that supports cognitive health, memory, and overall brain function, according to new research.
The study, highlighted by U.S. News & World Report on March 16, 2026, shows that exercise stimulates the production and release of brain-derived neurotrophic factor (BDNF), a protein often described as “Miracle-Gro for the brain.” BDNF plays a critical role in the growth, maintenance, and survival of neurons, as well as in the formation of new neural connections (neuroplasticity).
Researchers found that both aerobic exercise (such as running, cycling, or brisk walking) and resistance training significantly increase circulating levels of BDNF. The effect appears p...
