The Endurance Athlete’s Guide to VO2max and Lactate Tests
Find out all the dos and don’ts of physiological testing as we break down VO2max and lactate/ramp testing.
Humans aren’t machines—we’re much more complicated. Exercise physiology involves changes in the body from exercise and rest.
From anaerobic threshold to environmental acclimatization, from FTP to PGC-1 alpha, we explore the science of human performance.
Find out all the dos and don’ts of physiological testing as we break down VO2max and lactate/ramp testing.
We explore the physiology of race season—how to find top-end fitness, how long it takes, and the best ways to do it.
Your lactate threshold may not be what you think it is. Coach Trevor Connor explores the true definition of this physiological turn point.
Environmental physiologist Dr. Stephen Cheung addresses whether the amount of fat and carbohydrate used for energy changes with the temperature.
What are the keys to success in ultra running, and are they the same across all distances?
Dr. Stephen Seiler presents on the history and future of endurance sports testing and monitoring.
Coaches Trevor Connor and Ryan Kohler analyze the Power Duration Curve in order to illustrate how you can train fatiguability.
In this video, Dr. Seiler thinks out loud—with math—to explore how critical power and variable intensity races might connect in practice.
Coach Ryan Kohler reviews season-to-season changes in heart rate/power distributions to illustrate improvements across the different energy systems.
Cardiovascular drift is an instability in heart rate and stroke volume over time. We show you how to determine it.
Dr. Stephen Cheung discusses a study comparing steady-state versus fast-start intervals, then uses Xert software to model how a fast-start interval can be much more intense.
Dr. Stephen Seiler explores whether a Zwift race of about 60 minutes can be a decent substitute for a 60-minute FTP test.
In this workshop, Dr. Stephen Cheung uses Xert software to illustrate how a single workout can impact athletes differently depending on their phenotype.
Coaches Trevor Connor and Ryan Kohler analyze data from longer threshold efforts to support results garnered from the popular 20-minute power test.
Ryan and Trevor field questions on max heart rate, TSS, recovery in athletes who only train 8-10 hours per week, protein consumption during ultra-endurance events, and more.
Coaches Trevor Connor and Ryan Kohler analyze data from 20-minute power tests, offering important lessons on the proper execution of these intervals.
Coaches Trevor Connor and Ryan Kohler analyze ride data from one of Trevor’s LSD (long, slow distance) rides in order to explain the correct execution of one of these fundamental rides.
Coach Grant Holicky and head coach Ryan Kohler teach you how to analyze cyclocross power files in TrainingPeaks.
