The Greatest Show on Earth

less than 1 minute read

Published:

In this post, I discuss how AI techonologies might assist us to monitor and optimize the chronic physiological adaptations that occur with endurance training, as well as how AI models might be used subsequently to develop more data-driven and systematic approaches to training program design.

How AI is (not) going to change sport science

less than 1 minute read

Published:

In this blog post with this (for some) controversial title, I diuscss why I don’t believe that we need AI to become better coaches or better sport scientists. Indeed, we need AI to test old ideas, and form new ones, to stimulate debate, and move our optimization forward.
