Weekly MET Minutes

Sum weekly MET-minutes across activities against caller-defined bounds.

Description

MET-minutes combine activity intensity with duration.

MET-minutes combine activity intensity with duration. Summing them provides a volume measure under the supplied MET assignments.^[1]

Sum weekly MET-minutes across activities against caller-defined bounds.

When to use Weekly MET Minutes

Use this tool to sum weekly MET-minutes across activities against caller-defined bounds.

Prepare the measured movement, timing, load or preassigned score requested. Keep protocols, units, paired measurements and caller-selected thresholds consistent.

How to use Weekly MET Minutes and understand its results

Prepare the measured movement, timing, load or preassigned score requested. Keep protocols, units, paired measurements and caller-selected thresholds consistent.
Enter activityMets, activityMinutes, weeklyLower, weeklyUpper using the field table and calculation rules, then run the tool.
Read totalMetMinutes, withinWeeklyRange. The explanation below defines the units, signs, ordering and any flags or placeholder values.
If the tool reports an input issue, correct the values and run it again. Apply the stated assumptions when interpreting a successfully returned result.

Input field	Meaning	Value type; see rules below	Requirement
activityMets	Activity mets	list of number	Required
activityMinutes	Activity minutes	list of number	Required
weeklyLower	Weekly lower	number	Required
weeklyUpper	Weekly upper	number	Required

Enter nonempty aligned nonnegative intensities/durations and ordered nonnegative weekly bounds. Return total and inclusive within-range flag.

total=ΣMET_i×minutes_i

Units, indexing, boundary conditions and exceptional cases are defined in the calculation rules above.

Output field	Meaning	Value type
totalMetMinutes	Total met minutes	number
withinWeeklyRange	Within weekly range	boolean

Limitations and assumptions

No activity intensity is estimated, and the bounds are not embedded exercise guidelines.

Numeric inputs must be finite. Follow the calculation-specific rules for overflow, underflow and exceptional cases. Lists are limited to 100,000 entries; the rules above may require smaller limits. Missing required fields, extra fields, wrong value types and violations of the calculation rules are input errors. A successfully returned false flag is an evaluated outcome; its meaning is explained above.

Alternative or Complementary methods

Use MET Intensity Bands: Classify MET intensity using caller-selected light/moderate/vigorous boundaries. For a complementary task, use Session RPE Training Load: Calculate session-RPE training load in arbitrary units.
