RP#15: Running Science – VO2max, Running Economy, Lactate Threshold

Posted on March 20 2010

Runblogger Podcast LogoIn this episode I discuss the science behind three topics that are highly relevant to your running performance – VO2max, Running Economy, and Lactate Threshold. My initial plan was to produce this episode using clips from my Exercise Physiology class, but opted instead to record an off-the-cuff summary of the topic that’s a bit tighter and more focused. I find all of these topics fascinating, and understanding the science behind them explains a lot about why my performance in the Disney Marathon in January resulted in an 8:00 PR – I hope you find it interesting and informative as well!

This episode was recorded in my car on a drive to Maine, so the occasional hiss you hear in the background of the audio is the sound of snow/sleet pelting my windshield – I think I managed to clean out most of it so that it doesn’t disrupt things too much.
