That is speculation, and is unintuitive. Why would the brain "work hardest" when running? Why would modern humans not exert the same forces during sport? Why would humans, the top group-oriented predator, run from a lion?
The data linked above shows that observed Physical Activity Levels and caloric use are comparable to modern day. Stop inserting your own assumptions into the data.

- afarrell 10y agoBut what if it was coming at a group of ten of you and you were all armed with melee weapons? Ghost & The Darkness aside, lions generally don't hunt humans. But humans did spend a bunch of time pursuing game over long distances.
- searine 10y agoWe hunt lions for sport, and have for millennia. They are almost extinct because of it...
- fpoling 10y agoThe data do not indicate that we experience the same need to work at max energy for brief periods of time as hunter/gatheres. Besides running away from predators in most efficient way, consider throwing оf javelins or stones during hunting. It requires a very precise muscle work at max energy after intense brain activity of target selection. Modern day life does not involve that, yet evolutionary this combination of brain/muscle work at peak could be advantageous.
