Fast Physiology with Dr. Phil: FTP (Functional Threshold Power) Misconceptions

Training Babble: Off-Road Insights for Mountain Bike and Gravel Cycling

Summary
In this episode of Fast Physiology, Dr. Phil Batterson and Dave S discuss the concept of Functional Threshold Power (FTP) and its misconceptions. They explore different methods of measuring FTP and the importance of training at appropriate intensities. They also discuss the variability of FTP and the need for context in testing. Overall, FTP is seen as a range rather than a fixed number, and training strategies should focus on increasing time at or close to the second threshold.

Takeaways

• FTP is a field test that measures the highest power a rider can maintain in a quasi-steady state without fatiguing for around one hour.
• FTP is not a measurable physiological phenomenon, but rather a range of power output that represents the transition from sustainable to unsustainable physiology.
• Training strategies for increasing FTP can involve accumulating more time under or around the second threshold, depending on specific goals and race durations.
• FTP testing should be consistent and done in the same context to minimize variability and accurately track progress.
