Fitness, fatigue and form
Follow long-term fitness, short-term fatigue and their balance as CTL, ATL and TSB across the selected history window.
Load describes how training accumulates; volume shows how much work was recorded in each period. EffortSignal keeps both views connected without treating either one as a complete readiness verdict.

Follow long-term fitness, short-term fatigue and their balance as CTL, ATL and TSB across the selected history window.
Recommended fatigue, workload ratio and the following day's easy-load estimate remain calculation aids rather than medical or predictive claims.
Switch between weeks and months, filter by sport, and compare Duration, TRIMP or PSS without changing the underlying training record.
Recent totals can be shown against the athlete's own baseline. Partial periods and incomplete source coverage remain marked rather than reading as finished totals.
The chart and period summary show the selected scale, metric, sport and usual range together.

The full page keeps load and volume adjacent to current recovery and signal evidence.
