The Effects of Mental Fatigue on Physical Performance

How long can a human run without stopping? What’s the most weight a human can deadlift? Will someone ever run a mile in less than three minutes and thirty seconds?
My guest explores these questions in his latest book, and along the way uncovers insights into all the factors that go into pushing the limits of human athletic performance. His name is Alex Hutchinson and he’s the author of "Endure: Mind, Body, and the Curiously Elastic Limits of Human Performance." 
Today on the show, Alex and I discuss the history of the science of human performance and the three competing theories about how to measure and improve it. Alex first explains the interplay between physiology and psychology when it comes to humans pushing themselves. We then spend the rest of the conversation discussing factors that have an influence on our performance including pain, thirst, muscle strength, diet, and mental fatigue. Alex finally shares insights from the latest research on how you can manipulate these factors to run faster and longer and lift heavier weights.
