Acute load reflects your recent training effort, mostly from the past week. Heavier workouts weigh more, and older ones fade naturally over time. It helps track short-term fatigue.
How to read it
Acute load rises quickly after a hard week and falls quickly when you rest. On its own it only says how much you have done lately. It becomes useful next to your fitness level: the same acute load can be easy for a well-trained runner and far too much for someone returning from a break.
How Kiiro calculates it
Acute load is a weighted average of your daily training load over 7 days. Newer workouts count more than older ones, so the number moves smoothly instead of jumping when a workout drops out of the window.
In the app it is the “Acute load” line on the training load chart. How it compares with your fitness level is your load balance.
