You probably realize that ‘threshold’ is an important measure for endurance athletes. But there seem to be many different types of thresholds measures out there, and that might be confusing for some. In this episode, the panel explores the many types of thresholds (e.g. FTP, critical power, lactate threshold): how they are determined, whether they are the same or different, whether they are interchangeable, how they relate to each other, and what it all means for the real-world coach and cyclist. 2:31 What is ‘threshold’? 3:00 Exercise domains 10:45 What are the purposes of determining threshold? 14:33 What are the main thresholds measured in endurance sport? 18:15 Functional threshold power 23:48 Critical power 30:46 Lactate thresholds 40:37 Ventilatory thresholds 44:40 How the thresholds compare with each other 56:40 General conclusions 70:10 Thought experiment: does threshold even matter in modern endurance training?
