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 →

Comparing L/R Balance – Ramp Tests

I've been drawing up more comparisons of my historical L/R asymmetry, now that I know the source of the issue. Here's a quick comparison of previous ramp tests from the last three seasons, done around the same time of year. January 2016 Red is Left leg power Blue is Right leg power (each measured independently) … Continue reading Comparing L/R Balance – Ramp Tests →

Investigating Power Asymmetry using Pedaling Metrics

I've been using a 4iiii Precision Pro dual-sided power meter for the past two seasons. Having a dual-sided power meter has been critical for me, as I have a chronic injury which results in a significant Left/Right power asymmetry. A single-sided power meter that just doubles Left leg power (my weak side) would give me … Continue reading Investigating Power Asymmetry using Pedaling Metrics →

Update to ‘Prescribing VO2max’

My last post left off with a novel workout protocol for optimizing VO2max training, according to my synthesis of the literature and personal experimentation at the time. I was blown away by the amount of engagement and discussion generated by the post. The discussion helped me expand my own understanding, challenged my assumptions, and of … Continue reading Update to ‘Prescribing VO2max’ →
