Good day!
Recently (about 2 months) I have been mainly training in the pool or on a bike, but the endurance indicator either does not change after training or decreases.
Sleep, recovery and other indicators are at a good level. The battery is fully charged after a night.
The load during training, especially on a bike, is sufficient, including an anaerobic part.
Please help me understand this issue, why the anaerobic load decreases and how the data analysis algorithm works.
