The National Academy of Sciences is a private, nonprofit, self-perpetuating society of
distinguished scholars engaged in scientific and engineering research, dedicated to the
furtherance of science and technology and to their use for the general welfare. Upon the
authority of the charter granted to it by the Congress in 1863, the Academy has a mandate
that requires it to advise the federal government on scientific and technical matters.
Dr. Ralph J. Cicerone is president of the National Academy of Sciences.
The National Academy of Engineering was established in 1964, under the charter of the
National Academy of Sciences, as a parallel organization of outstanding engineers. It is
autonomous in its administration and in the selection of its members, sharing with the
National Academy of Sciences the responsibility for advising the federal government.
The National Academy of Engineering also sponsors engineering programs aimed at
meeting national needs, encourages education and research, and recognizes the superior
achievements of engineers. Dr. Wm. A. Wulf is president of the National Academy of
Engineering.
The Institute of Medicine was established in 1970 by the National Academy of Sciences
to secure the services of eminent members of appropriate professions in the examination
of policy matters pertaining to the health of the public. The Institute acts under the re-
sponsibility given to the National Academy of Sciences by its congressional charter to be
an adviser to the federal government and, upon its own initiative, to identify issues of
medical care, research, and education. Dr. Harvey V. Fineberg is president of the Institute
of Medicine.
The National Research Council was organized by the National Academy of Sciences in
1916 to associate the broad community of science and technology with the Academy’s
purposes of furthering knowledge and advising the federal government. Functioning in
accordance with general policies determined by the Academy, the Council has become
the principal operating agency of both the National Academy of Sciences and the Na-
tional Academy of Engineering in providing services to the government, the public, and
the scientific and engineering communities. The Council is administered jointly by both
Academies and the Institute of Medicine. Dr. Ralph J. Cicerone and Dr. Wm. A. Wulf are
chair and vice chair, respectively, of the National Research Council.

Independent Report Reviewers
This workshop summary has been reviewed in draft form by indi-
viduals chosen for their diverse perspectives and technical expertise, in
accordance with procedures approved by the National Research Coun-
cil’s Report Review Committee. The purpose of this independent review
is to provide candid and critical comments that will assist the institution
in making its published summary as sound as possible and to ensure that
the summary meets institutional standards for objectivity, evidence, and
responsiveness to the study charge. The review comments and draft
manuscript remain confidential to protect the integrity of the deliberative

Acknowledgments
The collective efforts of many individuals made it possible to plan
and conduct the Institute of Medicine (IOM) workshop on the Adequacy
of Evidence for Physical Activity Guidelines Development and to pre-
pare this workshop summary within a very short time frame. We are
grateful for the assistance of many individuals. RADM Penelope Slade-
Royall from the U.S. Department of Health and Human Services, Office
of Public Health and Science, Office of Disease Prevention and Health
Promotion (DHHS, OPHS, ODPHP) secured DHHS resources to sponsor
this effort. CAPT Richard Troiano and Jennifer Tucker from ODPHP,
Melissa Johnson from the President's Council on Physical Fitness and
Sports, and Harold W. (Bill) Kohl III from the Centers for Disease Con-
trol and Prevention provided useful suggestions in planning the work-
shop. Members of the planning committee (Bill Haskell, Rodney
Dishman, Joseph Donnelly, Bruce Jones, and Miriam Nelson) provided
invaluable input in planning the workshop agenda and speakers and pro-
vided feedback on specific issues related to the written summaries of the
presentations. The session speakers prepared insightful presentations,
and the discussants were instrumental in identifying areas of controversy
and providing supplementary information. The moderators kept the pre-
senters and discussants on task and synthesized the evidence presented in
the closing session.
We also appreciate the oversight for the National Academies’ review
process provided by Bronwyn Schrecker Jamrock and Clyde Behney,
skillful copyediting by Mark Goodin, formatting by Judy Estep,
manuscript preparation and reference checks conducted by Shannon
Wisham, and the careful review and oversight of the report production
process by Lara Andersen, Sally Stanfield, and others at the National
