To determine the contributions made by Academy Fellows during the past 75 years to concepts within the body of knowledge associated with exercise physiology, a literature search was undertaken. Of the charter Fellows, Hetherington and eight others (34%) were identified. Schneider in 1933 was the first of 18 Fellows who became authors, co-authors, or editors of exercise physiology textbooks for students in physical education or kinesiology. Of the 2005 membership, 21% were recognized as making one or more contributions to select concepts or to functions of biological systems. In rank order, the concerns were physical fitness assessment and guidance, gender responses, hormonal influences, thermal effects and thermoregulation, aging alterations, stress testing and the exercise training of individuals with cardiac risk factors, and body composition evaluation and guidance. Although few in numbers, Fellows of the Academy have also investigated the molecular biology of gene expression, characteristics of the genome, as well as changes within skeletal, connective, and immune systems.
