The next generation approach to metabolic profiling and training prescription will almost certainly not include breakpoints or thresholds at all, and will use more flexible methods of describing continuous physiological response profiles in real-time. I think that by defining the rules which our brains are already using to find patterns, we will be able to better understand the real physiological relationships for an individual athlete, and improve how we can apply insights to that individual athlete's training.
We are looking for subjects to participate in a remote cycling training study we are conducting through the University of Toronto, in partnership with TrainerRoad. This study will investigate the effects of high intensity interval training (HIIT) on cycling performance. If you are interested in participating and want more information, please go to
Muscle Oxygenation refers to the flux of oxygen within a target tissue as the result of oxidative respiration. Delivery of oxygenated blood from the heart & lungs and uptake or extraction of oxygen by the mitochondria within the local muscle. This is measured with a technology called near-infrared spectroscopy (NIRS)
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
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
