In this episode of the Training Science Podcast, Prof Paul Laursen sits down with Professor Anthony Turner to unpack the fundamental laws that underpin performance in every sport, from explosive team games to marathon running and cycling. Instead of debating opinions or trends, Anthony brings everything back to first principles: Newton’s laws of motion, impulse, force, and the biomechanics of movement.

Using endurance running as the main example, the conversation explores why strength training is just as essential as VO₂max and threshold for performance and economy. Ant explains how maximum strength and rate of force development shape running economy, ground contact time, stretch-shortening cycle efficiency, and ultimately time to exhaustion. They then extend these concepts to running, cycling, and long-term robustness.

Listeners will also learn how to progress strength logically: from movement quality and symmetry, to heavy lifting, to power work and plyometrics, all while staying healthy and reducing injury risk. Whether you coach team sports, work with endurance athletes, or train yourself, this episode will change the way you think about strength training, biomechanics, and sport performance.

Perfect for anyone interested in strength and conditioning, running economy, endurance performance, injury prevention, and applied sport science.
