they come to the conclusion 'These results show that the neural mechanisms underlying different running speeds in humans may be independent, just as in human walking and animal studies.' So they say slow running does not help for fast running from the neural perspective. Or in simple terms you improve your running form at that paces you train.
But are "they" runners? Because my experience tells me that if I can improve my easy running pace, I can improve my fast running pace. I'm not looking for shortcuts, because I know there are none.
It's all a continuum. Every pace from slowest to fastest is essential training. So yes slow running helps improve general conditioning.
Fair point. I have also the feeling that it helps.
E.g, if someone learns martial arts or even piano you start slowly to learn the movement pattern ...
