Podcast: Anaerobic Speed Reserve and More with Dr. Gareth Sandford

Untitled design (6)


ALTIS is an elite training environment for athletes, and a global leader of education in sport performance.

The latest ALTIS Podcast features Dr. Gareth Sandford and is hosted by Strength & Power Coach, Jason Hettler.

Gareth and Jason were members of our first Intern group in the Spring of 2014. Following his internship, Gareth joined Athletics New Zealand as a Performance Physiologist and completed his PhD with Auckland University of Technology.

He is currently a Post-Doctoral Researcher and Performance Physiologist with the University of British Colombia and the Canadian Sport Institute – Pacific. 

In this conversation Gareth and Jason cover many topics centered around Gareth’s PhD dissertation, Applications of Anaerobic Speed Reserve to Elite 800m Running. From a ‘big picture’ perspective they cover topics a variety of topics including asking the right questions and defining the relevant terminology. They then zoom-in on determinants of performance, categorizing athletes, and more.

The final third of the conversation centers around the application of Gareth’s work beyond the 800m, particularly into team sport.
