Abstract

BACKGROUND: The Compendium of Physical Activities was published in 1993 to improve the comparability of energy expenditure values assigned to self-reported physical activity (PA) across studies. The original version was updated in 2000, and again in 2011, and has been widely used to support PA research, practice, and public health guidelines. METHODS: This 2024 update was tailored for adults 19-59 years of age by removing data from those ≥60 years. Using a systematic review and supplementary searches, we identified new activities and their associated measured metabolic equivalent (MET) values (using indirect calorimetry) published since 2011. We replaced estimated METs with measured values when possible. RESULTS: We screened 32,173 abstracts and 1507 full-text papers and extracted 2356 PA energy expenditure values from 701 papers. We added 303 new PAs and adjusted 176 existing MET values and descriptions to reflect the addition of new data and removal of METs for older adults. We added a Major Heading (Video Games). The 2024 Adult Compendium includes 1114 PAs (912 with measured and 202 with estimated values) across 22 Major Headings. CONCLUSION: This comprehensive update and refinement led to the creation of The 2024 Adult Compendium, which has utility across research, public health, education, and healthcare domains, as well as in the development of consumer health technologies. The new website with the complete lists of PAs and supporting resources is available at https://pacompendium.com.

TL;DR

The 2024 Adult Compendium of Physical Activities is the third update of the Compendium, providing standardized MET values for 1114 Specific Activity codes across 22 Major Headings for adults aged 19–59 years. It adds 303 new Specific Activity codes, increases measured MET coverage to 912 of 1114 activities (82%), and introduces a new Video games Major Heading.

Key findings

  • The 2024 Adult Compendium contains 22 Major Headings and 1114 Specific Activity codes, compared with 821 Specific Activities in the 2011 Compendium.
  • Measured MET values now cover 912 PAs (82%) versus 561 of 821 PAs (68%) in 2011; estimated METs comprise 18.5% of the Adult Compendium.
  • The update added 303 new Specific Activity codes with measured METs and made 176 changes to MET values or Specific Activity descriptions from the 2011 Compendium.
  • The systematic review identified 32,173 abstracts; after removing 10,868 duplicates, 21,137 abstracts were screened, 1507 full-text articles were reviewed, 701 articles were used for data extraction, and 2356 new PA energy expenditure values were incorporated.

Methods

  • A research librarian conducted a systematic search for articles and abstracts published from January 2011 through March 2023 using PubMed, Embase, SPORTDiscus, and Scopus, with 22 separate keyword searches pairing Compendium Major Heading activity concepts with energy-cost terms.
  • Articles were included if participants had a mean age of 19–59 years, PA energy cost was measured using indirect or direct calorimetry, and articles/abstracts were available in English; exclusions included resting/peak/maximal values only, disability restricting PA, estimated EE from heart rate monitors, motion sensors, or prediction equations, and pregnant or chronic disease participants.
  • Data extraction covered participant age and EE data such as METs and VO2; values reported in other units were converted to standard METs using a standardized resting metabolic rate of 3.5 mL/kg/min, and the 2024 Compendium maintained the same 5-digit coding scheme with MET values rounded to 0, 3, 5, and 8.

Limitations

  • The paper states that categorizing energy costs of water PAs such as surfing and scuba diving, or live sports such as boxing and American football, remains challenging due to limitations of existing measurement strategies.
  • The paper states the 2024 Adult Compendium is intended for non-disabled adults and adults without significant health conditions affecting EE or metabolism, and is limited to adults 19–59 years of age.
  • Evident from the text: the Compendium still relies on estimated METs for some Specific Activities, and the paper reports estimated values as 202 in Table 3 but as 207 in the strengths and limitations section, an internal inconsistency in the reported count.

      The Results (Gross Heart Rate and V̇O2; page not available) report a significant difference in oxygen consumption when Madden was played on Wii versus PS2, supporting variation between versions of the same game. But the Methods (Protocol; page not available) say all games were played at the least difficult setting, and the paper does not link energy expenditure to difficulty level or player experience. Its discussion of how vigorously participants might play is speculative, not an observed within-game effect of effort. (LLM, conf=0.84)

  • Probably not a substantial claim: may not pass S3 (load-bearing).

    Due to the variation in RMR between individuals, relative, standard, and corrected METs understandably differ.

    Collectively, the revisions in the 2024 Adult Compendium provide standard MET values for adults to assist researchers, practitioners, and public health specialists in assigning and describing intensity to a wide range of PAs commonly performed in a variety of settings, including inactivity, leisure, transportation, sports and conditioning, and in-home and occupational settings.

    The 2024 Adult Compendium builds upon that utility as a standardized and comprehensive source of broadly described Major Headings and the energy expenditure costs associated with 1114 Specific Activity codes.

    The 2024 Adult Compendium is intended for use in non-disabled adults and adults without significant health conditions that affect energy expenditure or metabolism.

    “As with prior versions of the Compendium, the 2024 Adult Compendium is intended for use in non-disabled adults and adults without significant health conditions that affect EE or metabolism (e.g., heart failure patients, patients with chronic obstructive pulmonary disease, pregnant women, adults with Down Syndrome).”

  • Probably not a substantial claim: may not pass S3 (load-bearing), S4 (based).

    Interpretationnone given

    For over 30 years, the Compendium has set a global standard used to identify the energy expenditure cost of Specific Activity codes ranging from sedentary behaviors to an abundance of PA variations.

    Categorizing the energy costs of water PAs like surfing and scuba diving or during live sports activities such as boxing, American football, and other team sports continues to be a challenge due to the inherent limitations of existing measurement strategies.

  • The paper relies on this without support.

    Measured MET values are preferable to estimated MET values for the Compendium.

    “continue to replace estimated MET values with measured MET values where available”
    “We also replaced some estimated MET values in the 2011 Compendium with measured values”

Self-check

Percentages, sums and reported differences re-computed from the paper’s own numbers.

Each contradiction between two passages listed here was confirmed by an independent check.

  • Estimated activities are not 18.5% of the reported total

    Minor

    Table 3 reports 202 estimated activities out of 1,114 total, which is about 18.13%, rather than 18.5%.

    Reported 18.5 · recomputed 18.132855

  • Two different counts of estimated values in 2024

    Minor

    The strengths and limitations section gives 207 estimated values for the current update, whereas Table 3 gives 202.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Claims read by deepseek-v4.1-flash under definition version 3 (extract-v3) on 2026-10-06.

Classified by jev-1.13-20260917 (gold-guideline-v0.2) on 2026-10-06.

Cited sources are checked by gpt-6-sol.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
