The Conversation: Why are some people faster than others? 2 exercise scientists explain the secrets of running speed


Usain Bolt, the world’s fastest human, ran a 100-meter sprint at a speed of 23.35 miles per hour (37.57 kilometers per hour).

That’s mind-blowingly fast for a human. It’s about the same speed as cruising in a car through your neighborhood or in a school zone. It might not seem that fast when you’re in the car, but is is for a person. Few runners in the world can even come close.

Dawn Coe and Elizabeth (Kip) Webster, associate professors of exercise science, answered the question, “Why are some people faster than others?” for The Conversation’s Curious Kids series. Read the full article on The Conversation.
