Purpose: The Compendium of Physical Activities was developed to enhance the comparability results across studies using self-report physical activity (PA) and is used quantify energy cost a wide variety PA. We provide second update Compendium, called 2011 Compendium. Methods: retains previous coding scheme identify major category headings specific PA by their rate expenditure in MET. Modifications include cataloging measured MET values source references, when available; addition new codes...

A coding scheme is presented for classifying physical activity by rate of energy expenditure, i.e., intensity. Energy cost was established a review published and unpublished data. This employs five digits that classify purpose (i.e., sports, occupation, self-care), the specific type activity, its intensity as ratio work metabolic to resting (METs). expenditure in kilocalories or per kilogram body weight can be estimated all activities, types. General use this system would enhance...

Previous measures of physical activity for epidemiologic studies were considered inadequate to meet the needs a community-based health education trial. Therefore, new methods quantifying habits communities developed which are practical large surveys, provide information on distribution in population, can detect changes over time, and be compared with other activity. Independent self-reports vigorous (at least 6 metabolic equivalents (METs) ), moderate (3-5 METs), total energy expenditure...

Abstract Assessment of habitual physical activity in epidemiologic and health education studies has been difficult A seven-day recall interview was developed administered a community survey, randomized clinical trial, two worksite promotion programs during 1979–1982. These were conducted several populations California, Texas, Pennsylvania, New Jersey. Energy expenditure estimates from the conformed to expected age- sex-specific values cross-sectional survey. Estimates energy also congruent...

We studied separately the influence of two methods for losing fat weight on levels plasma lipids and lipoproteins in overweight sedentary men — decreasing energy intake without increasing exercise (diet), expenditure altering (exercise, primarily running) a one-year randomized controlled trial. As compared with controls (n = 42), dieters 42) had significant loss total body (-7.8±0.9 kg [mean ±SE]), (-5.6±0.8 kg), lean (nonfat) (-2.1±0.5 kg) (P<0.001 each variable), exercisers 47) (-4.6±0.8...

Limited data are available on the relation between physical fitness and mortality from cardiovascular disease. We examined this question in a study of 4276 men, 30 to 69 years age, whom we followed for an average 8.5 years. Examinations at base line included assessment conventional coronary risk factors treadmill exercise testing. The heart rate during submaximal (stage 2 test) duration were used as measures fitness. Men with incomplete (n = 308) or who using drugs 213) excluded analysis....
