“∆ Power @AVT1 (Mets)” is about the change in how hard you can exercise at a specific point called the anaerobic threshold 1, measured in Metabolic Equivalents (Mets). Think of it like a level in a video game. At AVT1, you’re exercising so hard that talking becomes tough. Mets is a way to measure how intense your activity is, like how fast you’re running. This category shows how this intensity level changes after a treatment or condition. For instance, if you could run at a certain speed before and now you can run faster at the same effort level, that’s what this number is showing.
