Your focus on the brain is too narrow. Competition leads to adrenaline which triggers the body outside the brain to burn more calories (elevated body heat, etc). I'd bet these players have elevated body heat - ever sweat during a stressful meeting or exam?
- Retric 5y agoAdrenaline increases capillary blood flow which actually lowers core body temperature in preparation for action action. You can watch grand masters play, their generally not fidgeting or pacing etc. They do sweat, and I would believe 4K but it’s nowhere near enough for 6k calories per day.
- checker 5y agoOk yeah, just wanted to point out that assuming that the brain has to be the one burning these calories seems too narrow when it's the body as a system being analyzed. Definitely not an expert here, so your napkin math might be true.
