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.
Coaches have known about the importance of durability for years, but researchers are only just starting to catch up. We discuss why it is the fourth pillar of performance.
The cardiovascular system powers endurance performance. Explore how training reshapes the heart, what causes cardiovascular drift, and why too much exercise may carry long-term risks.
An athlete’s rate of perceived exertion, or RPE, is one of the most underappreciated metrics. For ultra-athletes who are closely in touch with their bodies and minds, working with RPE is an essential component to training and racing.
