Hard-start intervals use an initial hard effort at a power output above what would be sustainable for the intended interval duration, to enhance oxygen uptake and cardiac output. Let's talk about some of the reasons for why we might want to perform hard-start intervals, when they might be appropriate for our training, and when they might not be.
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
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’
June 11, 2020 - UPDATE As an update into my current thinking, HR is simply too variable to be a reliable metric for internal training load near VO2max. Both the strength and weakness of HR is that it is sensitive to many internal and external factors. This limits it's correlation to any one single factor, … Continue reading Prescribing VO2max
Most of the amateur bike racers I know are limited by time available to train. I think this is a relatable limitation to all of us... So wouldn't it be nice if an amateur endurance athlete could optimize the time they do have available to train, by establishing a minimum effective dose for eliciting adaptations. … Continue reading Optimized Aerobic Prescription
