Pretty much the same biological factors with modern man vs ancient man (with regards to strength/speed). Though the brain is meeting more stimulus and adapting abilities now-a-days.. The fight or flight element was much more of prime daily influence then, as compared to now. Requiring great burst of speed or strength. Had to adapt to their surroundings or die. If modern man were thrown into such a element he would adapt also or die trying.
A throw back to the ancient human is when you may read that a 70 year old grandmother lifts the back end of a car off her grandchild. Funny thing is, she may be a little sore the next few days, but usually nothing major. No breaks, serious strains, etc. Her primal influences (fight or flight) adapted to the need at the time. And in theory, we all could do that.
Weight lifters try to tap into that hidden reserve of ancient raw energy before a big lift. Given all this, wonder if granny could be trained for a 1000lb DL and beat those 330lb fat guy's who waddle up to a bar? The potential awesome strength is with-in her, like everyone else. Have been studies using hypnotism with limited success. Also drug produced rushes. Also with limited success. Tend to be too much demand and strain on the heart and CNS. Too much danger to the body. Good Luck
