∆ @VT1 (L/min) – Change in Ventilatory Threshold 1

The term “∆ @VT1 (L/min)” refers to the change in the first ventilatory threshold, measured in liters per minute. Imagine you’re jogging, and there’s a moment when you start breathing really hard – that’s VT1. It’s like a sign that your body is beginning to work a lot harder. The “∆” (Delta) means change. So, this category tells us how much this heavy-breathing point changes after something like a new exercise routine or a medicine. For example, if this number goes up, it means you’re able to jog longer or faster before you start breathing hard.
