ACWR
ACWR is the ratio between acute load (recent days) and chronic load (previous weeks); it is a monitoring tool, not an injury predictor. Athlo lets you configure ACWR profiles with rolling average or EWMA, and coupled or uncoupled calculation.
Glossary
The terms, in one sentence.
ACWR, sRPE, HSR and the rest of the load, wellness and planning vocabulary that shows up in Athlo, explained plainly.
Acute load
Acute load is the load accumulated over a player's recent period, typically the last seven days.
Chronic load
Chronic load is the load accumulated over a longer period, typically the last four weeks, used as a reference for what the player has been tolerating.
Rolling average
A rolling average is a way to calculate acute or chronic load that weighs every day in the chosen window equally, for example 7 or 28 days.
EWMA
EWMA is an exponentially weighted moving average: it weighs recent days more heavily and older ones less, rather than treating them all the same as a rolling average.
Coupled / uncoupled
Coupled and uncoupled are two ways to calculate ACWR: in coupled, acute load is part of chronic load; in uncoupled, the two are calculated over periods that do not overlap.
Optimal zone
The optimal zone is a reference range around which load is considered well balanced, without sharp spikes or drops.
Monotony
Monotony is a measure of how even the week's load was: the daily average divided by its variation. A very monotonous week does not distinguish hard days from light ones.
Strain
Strain is monotony multiplied by total weekly load; it combines volume and a lack of variation into a single number.
sRPE
sRPE is RPE multiplied by the session's duration in minutes: a simple way to estimate a training session's internal load. Athlo logs the player's RPE after every session, and staff can also enter responses in bulk.
Internal load
Internal load is the player's bodily response to training, estimated from signals such as RPE rather than measured directly.
External load
External load is the objective physical work a player performs — distance, speed, accelerations — that a GPS typically captures.
HSR (high-speed running distance)
HSR is the distance covered above a high velocity threshold, configured according to the file's source system.
Sprint distance
Sprint distance is the distance covered above an even higher velocity threshold than HSR, associated with maximal efforts.
HMLD
HMLD is high metabolic load distance: it combines speed and acceleration to estimate the energetic cost of movement.
Player load
Player load is a composite metric that summarises the mechanical load of tri-axial acceleration during a session; its exact calculation depends on the file's source system.
MD-x (matchday)
MD-x is a convention for naming microcycle days by their distance from the match: MD-1 is the day before, MD+1 the day after.
Microcycle
A microcycle is the training week organised around one or more matches. Athlo plans training sessions and matches with date, time, microcycle context, call-up and participation.
Wellness
Wellness is a short daily questionnaire on how the player arrives: sleep, muscle soreness, mood, stress, among other questions. Athlo lets you configure daily wellness with numeric or single-choice questions and visual thresholds.
Daily checklist
The daily checklist is a record of squad care tasks: hydration, prehab, nutrition. The daily checklist lets staff record squad compliance from an editable grid.
Physical target (in zone, near zone, out of zone)
A physical target is a reference range for a physical metric, split into compliance zones. Athlo lets you set physical targets for the whole squad, by position or by player, with in-zone, near-zone and out-of-zone ranges.
Availability
Availability is a player's operational status to train or play; it is not a medical diagnosis. Athlo records unavailability periods with reason, dates and history to keep a consistent operational reference.
Operating period
An operating period is a window of time, such as a season, over which squads, sessions and analysis are organised. Athlo manages seasons and squads while keeping each player's historical link to the team.
Alias (import)
An alias is a saved mapping between a column in your GPS file and the Athlo metric it corresponds to. Confirmed mappings can be learned to simplify future imports.
