When Muscles Work Against Resistance, Redox Signaling Helps Protect and Support the Brain
In this review, the authors describe how resistance exercise activates the body’s built‑in antioxidant systems in the brain, helping maintain a healthy internal environment for nerve cells. Studies reviewed in the paper suggest that regular strength training is associated with better cognitive function—especially skills like attention, planning, and memory—particularly as people age. Overall, the paper shows that resistance exercise helps keep the brain resilient by supporting the muscle‑to‑brain communication systems that regulate redox balance and mental performance, not just physical strength.
