Sports Talks

In today’s episode, Sam sits down with Dorothy Hummel, one of the most advanced human performance practitioners in the world — specialising in neurogenetics, biochemistry, neurochemistry, behaviour, and brain-body performance integration.Most coaches focus on strength, conditioning, marginal gains, recovery tools, or mental skills — but Dorothy reveals why none of it works optimally unless you understand the brain’s biochemical blueprint.This conversation will fundamentally change how you think about: • speed training • recovery • injuries (ACL, hamstrings, chronic issues) • athlete readiness • performance psychology • stress, arousal & game-day output • sleep • nutrition • interventions that actually work • and why “guesswork coaching” is outdatedIf you’ve ever wondered why two athletes do the same training and get totally different results… THIS is the missing link.Dorothy breaks down how genetics, neurochemistry, methylation, dopamine regulation, stress hormones, inflammation and biochemistry determine
