VO2max and Metabolic Testing: “Are You a Sugar Burner or a Fat Burner?”

New post on VO2max testing and the benefits for endurance athletes! Here’s an excerpt.  Check it out and let me know what you think! 

Why do VO2max or metabolic testing?

  • quantify how efficient you are and how you can be more efficient
  • monitor progression
  • improve body composition and thus performance


Metrics of Performance Assessment (factors that can be monitored to improve performance)

  • pace/power at lactate threshold
  • VO2max
  • % of VO2max at lactate threshold
  • Calorie Utilization (carb/fat or RER/RQ)
  • Body composition


VO2max is essentially the amount of oxygen that your body is able to extract and use during maximal exercise.  You can improve your VO2max to a certain point that your genetic potential allows.  In fact, an individual’s highest VO2max can be reached after just 12 - 18 months of intense endurance training.  However, you can continue to improve your performance even if your VO2max is the greatest it will ever be.  How?  One way is to improve your lactate threshold.

Lactate threshold is the point when lactate production outpaces lactate clearance in the body and lactate starts to accumulate rapidly in the body.  This process also marks the point at which a person goes from primarily aerobic metabolism (when the body is able to take in enough oxygen to power activity) to anaerobic metabolism (when the body is fueling your activity without oxygen).

Anaerobic metabolism can only provide energy for a short period of time so once you surpass lactate threshold, you will fatigue very quickly.  Therefore, increasing lactate threshold allows you to perform at a higher level of intensity without burning out.

Macca Shooting for London Olympics

authenticitysports:

This is awesome. There isn’t a better way to describe it. Macca is one of the greatest triathletes ever—he’s raced and won just about every race of significance on the planet and this is the only thing that’s eluded him. I’m getting goosebumps just reading this article. I know that same raw emotion just blasting through his veins right now. Awesome. Just awesome. More to follow!

werapidsk8: OK, so this bike has won more than any other in history – by a country mile. But more importantly, it is the most used bike at Ironman racing and time trialing ever – by “regular” customers. No wonder it is still the reference for the entire bike industry, and the most copied bike in history. Yet its popularity remains, because the original is still unmatched.  Only if this came with a girl in a “Itsy Bitsy Teenie Weenie Yellow Polka Dot Bikini”.
