Use weekly direction over daily noise
Single-day jumps can be noisy. Weekly and block-level direction is more reliable for planning.
How to read effective VO2max trend
Use trend direction, load pressure, and session quality together before changing plan intensity.
Pair trend with CTL and ATL
If trend stalls while ATL remains elevated, reduce stress before adding more volume.
Check execution quality before edits
Trend drops are more actionable when they align with degraded key-session quality.
Apply one adjustment at a time
Keep frequency stable, change one variable, and reassess after the next quality session.
Is effective VO2max enough to change my plan?
No. It should be combined with load and execution signals before modifying training targets.
How often should I review effective VO2max trend?
A quick daily scan is fine, but weekly and block reviews drive better decisions.
Can trend decline happen even with high training load?
Yes. Excess stress or poor recovery can suppress adaptation despite high load volume.
