Metabolic Steady State – Inside vs Outside

A few weeks ago I performed a series of steady-state submaximal 30min intervals, looking at VO2 & ventilaton with the VO2 Master Pro and muscle oxygenation (SmO2) with Moxy. The first trial was inside on the trainer, followed a few days later by the second trial outside on the road. The purpose was to observe … Continue reading Metabolic Steady State – Inside vs Outside

Deriving Power from VO2 and VO2 from Power

The charts we looked at last week have some 'hidden' interesting features that I want to go into more detail on. This will get into mathematical derivations of metabolic equations, estimating Gross Efficiency, fuel utilization between fatty acids & glucose, and aerobic & anaerobic contribution to power output. This might get complicated, but it will … Continue reading Deriving Power from VO2 and VO2 from Power

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
