Research has shown that physical activity increases levels of BDNF, also known as brain‑derived neurotrophic factor, a protein that supports neural growth, synaptic connectivity, learning, and memory.
Higher BDNF is linked to better attention and decision‑making. As someone enrolled in martial arts myself, I can attest to the research that shares activities that combine movement and mental concentration -- like martial arts or gymnastics -- were the ones that most helped improve BDNF levels.
