He also plays soccer, so in parts of that season it will naturally be somewhat less.
And short bursts of high-intensity. WIth mostly Z1 training, that’s a good combination.
Given that he is young, my approach is that the activity should be motivated by whats fun, more than being too rigid and systematic.
Wise. It takes upwards of ten years for full aerobic development, usually occurring in the early-30s. If he likes endurance sports, you don’t want him to burn out too soon.
The test confirmed our estimate of AeT around 195/196 bmp (based on experience from uphill running) and a Lactate threshold at 199 bmp (2.9 mmol). Based on this, the training zones were estimated at:
Zone 1 162-192 / Zone 2 193-196 / Zone 3 197-201 / Zone 4 202-204 / Zone 5 205-
This is an exceptionally narrow aerobic gap. How was AeT measured? What lactate value? What was the test protocol?
