![]() The 2011 Compendium is an update of a system for quantifying the energy cost of adult human PA and is a living document that is moving in the direction of being 100% evidence based. 2011 Compendium of Physical Activities CODE METS MAJOR HEADING SPECIFIC ACTIVITIES Italicized codes and METs are estimated values 01003 14.0 bicycling bicycling, mountain, uphill, vigorous 01004 16.0 bicycling bicycling, mountain, competitive, racing 01008 8. The Compendium is used globally to quantify the energy cost of PA in adults for surveillance activities, research studies, and, in clinical settings, to write PA recommendations and to assess energy expenditure in individuals. Updated MET values accounted for 73% of all code changes. Approximately half (317/604) of the codes from the 2000 Compendium were modified to improve the definitions and/or to consolidate specific activities and to update estimated MET values where measured values did not exist. Methods We sought to design and validate an historical adulthood PA questionnaire (HAPAQ) against. Previously reported historical physical activity (PA) questionnaires appear to be reliable, but their validity is less well established. Compendium of Physical Activities: an update of activity codes and MET intensities. Background Lifetime physical activity energy expenditure (PAEE) is an important determinant of risk for many chronic diseases but remains challenging to measure. Two hundred seventeen new codes were added, 68% (561/821) of which have measured MET values. Purpose: The Compendium of Physical Activities was developed to enhance the comparability of results across studies using self-report physical activity (PA). 5.Ainsworth BE, Haskell WL,Whitt MC, Irwin ML, Swartz AM, Strath SJ, et al. A coding scheme is presented for classifying physical activity by rate of energy expenditure, i.e., by intensity. The 2011 Compendium contains 821 codes for specific activities. Activities Completed Over Time in 24 Hours (ACT24) is an internet-based previous-day recall that was adapted from interviewer-administered recalls 30,31,32. A coding scheme is presented for classifying physical activity by rate of energy expenditure, i.e., by intensity, and general use of this coding system would enhance the comparability of results across studies using self reports of physical activity. Measured MET values were obtained from a systematic search of databases using defined key words. Modifications in the 2011 Compendium include cataloging measured MET values and their source references, when available addition of new codes and specific activities an update of the Compendium tracking guide that links information in the 1993, 2000, and 2011 compendia versions and the creation of a Web site to facilitate easy access and downloading of Compendium documents. The 2011 Compendium retains the previous coding scheme to identify the major category headings and specific PA by their rate of energy expenditure in MET. We provide the second update of the Compendium, called the 2011 Compendium. ![]() The Compendium of Physical Activities was developed to enhance the comparability of results across studies using self-report physical activity (PA) and is used to quantify the energy cost of a wide variety of PA.
