More Comparisons for Hard-Start VO2max

I wanted to share a quick visual comparison of another athlete trying the Hard-Start VO2max workout. This might be helpful for comparing your own data in Strava and dialing in your individualized workout targets. The athlete wasn't sure of his precise power targets, so he plugged in something reasonable and gave it a go. After … Continue reading More Comparisons for Hard-Start VO2max

Comparing Metabolic Response to Hard-Start VO2max Intervals

This week I want to look at VO2 and SmO2 response to one of my favourite VO2max workout protocol. We will see how systemic metabolism responds to hard-start VO2max intervals. The experiments were fascinating and I'll try to give some recommendations to dial in your own individual workout prescription. Hard-Start Intervals The principle of the … Continue reading Comparing Metabolic Response to Hard-Start VO2max Intervals

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
