VO2 Measured to Modeled

Recently I was asked to compare how closely WKO-modeled VO2 (VO2mod) tracks against actual measured VO2. My last few articles looked at how measured pulmonary VO2 (pVO2) tracked with HR for both continuous and intermittent workouts. So let's look again at a few VO2max intervals and see how well the modeled numbers track to measured … Continue reading VO2 Measured to Modeled →

Comparing 30/15 VO2max Intervals

I want to look at my other favourite VO2max workout, the Rønnestad style Hard-start 30/15s VO2max workout. This was the protocol I arrived at based on Rønnestad, Seiler, Buchheit & Laursen, and others' research into optimizing interval prescription for maximizing adaptations to VO2max.

VO2 Master Pro & Moxy – Revealing Metabolic Limitation – Part 2

Let's continue looking at the Sprint Interval Training workout from Part 1. Using the VO2 Master Pro wearable VO2 analyzer and Moxy muscle oxygen monitors together to measure systemic oxygen consumption (VO2), and local muscle oxygen saturation (SmO2). Sprint Interval Training - Complete Recovery Intervals We left off with the suggestion that O2 delivery to working muscle was limiting the rate of … Continue reading VO2 Master Pro & Moxy – Revealing Metabolic Limitation – Part 2 →

VO2 Master Pro & Moxy – Revealing Metabolic Limitation – Part 1

I've been using a few new sensors in my training and coaching practice recently and learning a ton about central and peripheral limiters to performance. The sensors are the VO2 Master Pro wearable VO2 analyzer and Moxy muscle oxygen monitor. Together these sensors have given me a better view of systemic oxygen consumption (VO2), and local … Continue reading VO2 Master Pro & Moxy – Revealing Metabolic Limitation – Part 1 →

Comparing Steady Power to Decreasing Power

Just a cool comparison from my workout yesterday, that offers a chance to compare steady-power 30/15s intervals to decreasing-power 30/15s intervals. I set out to do 3x sets of my favourite VO2max workout, because with the vascular issue in my leg I'm scared of I can't do more effective continuous power workouts. I wasn't sure what my … Continue reading Comparing Steady Power to Decreasing Power →
