Can Bigger Muscles Give You A Bigger Brain? - With Louisa Nicola
Digest
This podcast explores the fascinating connection between muscle mass, particularly leg muscle power, and brain health. A twin study highlighted a correlation between larger leg muscles and a larger hippocampus (memory center), leading to improved cognitive function. The discussion delves into how muscles act as endocrine organs, releasing myokines—hormones that benefit brain health and potentially reduce cancer risk. Effective strategies for building leg power, emphasizing explosive movements like jump squats and box jumps, are detailed. The surprising benefits of creatine for brain health are discussed, with a recommendation of 10-20 grams daily for optimal brain saturation. Other crucial nutrients for brain health, including omega-3 fatty acids, B vitamins, polyphenols, and vitamin D, are also highlighted. The podcast also touches upon the cognitive benefits of challenging video games like Super Mario Bros., emphasizing the importance of novelty and challenge for brain plasticity. Finally, listeners are encouraged to connect with the guest neuroscientist for further information on neuroethletics and longevity.
