Scientific research reported within PubMed reveals a clear connection linking higher leg muscle power to better overall brain wellness. Evidence indicates people possessing stronger lower body muscles often display increased brain size and improved retention of gray matter throughout aging. Greater leg power is further associated with sharper cognitive abilities, including recall, focus, and mental processing speed. One suggested mechanism proposes regular movement boosts circulation, oxygen supply, and triggers neuroprotective growth chemicals that preserve brain structure and function. Collectively these results imply sustaining powerful leg muscles can meaningfully help safeguard long term cognitive health across the human lifespan overall safely broadly.
