The extent to which skeletal muscle (SM), a major body mass component, varies between people of the same sex, weight, height, and age is largely unknown. The current study aimed to explore the magnitude of muscularity variation present in adults and to examine if variation in muscularity associates with other body composition and metabolic measures.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>\n                      Muscularity was defined as the difference (residual) between a person's actual and model\u2010predicted SM mass after controlling for their weight, height, and age. SM prediction models were developed using data from a convenience sample of 492 healthy non\u2010Hispanic (NH) White adults (ages 18\u201380\u00a0years) who had total body SM and SM surrogate, appendicular lean soft tissue (ALST), measured with magnetic resonance imaging and dual\u2010energy X\u2010ray absorptiometry, respectively; residual SM (SM\n                      <jats:sub>R<\/jats:sub>\n                      ) and ALST were expressed in kilograms and kilograms per square meter. ALST mass was also evaluated in a population sample of 8623 NH\u2010White adults in the 1999\u20132006 National Health and Nutrition Examination Survey.
