Brain tissue may be fuel for marathon runners
- Bimos 3y agoDear body, please try to burn my belly before burn my brain.
- LargoLasskhyfv 3y agoTsss. Open your mind, and trust your gut feeling ;->
- mcmoor 3y agoFunnily, that's how it really fees like whenever I try to diet. I can't really expect myself to be productive if I am on calorie deficit.
- andreareina 3y agoI'd like to see a follow-up to see how it's correlated to nutrition strategies pre and post race. The only info we have is that the subjects (n=4) were male and "well trained"[1], nothing I could find about their weight or body composition, or even how hard they ran their marathons! [1] in the studies I've seen "well trained" usually means a VO2 max >= 70 ml/kg/min but that would be quite a feat for the oldest participant at 75!
- Bimos 3y agoOn the last page of the paper [1], the runners' data are shown. Age: 73/59/45/46, weight(kg): 58/76/69/71, finish time: 345/359/440/606, heart rate: 150/145/152/NA. I wish I could sub 4 at the age of 70s. [1] https://www.biorxiv.org/content/10.1101/2023.10.10.561303v1 https://www.biorxiv.org/content/10.1101/2023.10.10.561303v1

But you can’t rule out the effects of dehydration, Bouhrara says. If runners are dehydrated after their race, their brain tissues may just be dried out.
