Active Voice: Does Cardiorespiratory Fitness Level Trump LDL-Cholesterol Level for Predicting CHD Mortality?
By Steve Farrell, Ph.D.
Viewpoints presented in SMB commentaries reflect opinions of the authors and do not necessarily reflect positions or policies of ACSM.
Dr. Farrell is the science officer for the Division of Education at The Cooper Institute in Dallas. He and his colleagues have delivered health and fitness workshops around the globe for the past 30 years. His main area of research focuses on the associations among cardiorespiratory fitness, adiposity, and various health outcomes. This commentary presents Dr. Farrell’s views associated with the research article he and his colleagues published in the November issue of ACSM’s Medicine and Science in Sports and Exercise® (MSSE).
There is broad consensus that elevated levels of LDL cholesterol and low levels of cardiorespiratory fitness (CRF) are powerful independent risk factors for coronary heart disease (CHD). Is it possible that one might be a stronger predictor of CHD mortality than the other? My colleagues and I designed a study that would look at all possible combinations of CRF and LDL and the subsequent risk of CHD mortality. In this study, recently reported in MSSE, we followed 40,718 apparently healthy men who underwent a comprehensive baseline physical exam at the Cooper Clinic during 1978-2006. All men had a maximal treadmill stress test and blood work at the time of their exam. We divided the group into three categories of CRF:
Low fit: the bottom 20% (1st quintile) compared to other men in their age group.
Moderate fit: the next 40% (2nd and 3rd quintile) compared to other men in their age group.
High fit: the top 40% (4th and 5th quintile) compared to other men in their age group. More
Q&A with Francis O'Connor, Senior Editor of ACSM's "Sports Medicine: A Comprehensive Review"
Col. Francis G. O'Connor, MD, MPH, FACSM, is associate professor of military and emergency medicine at the Uniformed Services University of the Health Sciences and medical director of the USUHS Consortium for Health and Military Performance (CHAMP). SMB talked with him recently about the new book.
1. Why this book? What niche or need does it fill, when there are already so many books about sports medicine?
This book's intent is unique in that is designed to be the premiere resource for board preparation and review; additionally it is multidisciplinary with contributing editors from primary care sports, orthopedics, physical medicine, and athletic training. Authors are from all medical and related specialties.
2. In addition to those preparing for board exams, does it cover developments that established sports physicians should know?
The book is current, with questions that are current, as well as all ACSM position stands and statements on line. The text also inlcudes cutting edge chapters on topics such as Ultrasound and Platelet Rich Plasma.More
Policy Corner: NIH Grant Funding Update
On October 11th, NIH issued a notice announcing that “non-competing research grant awards will be funded below the level indicated in the most recent Notice of Award (generally up to 90 percent of the previously committed level) until the fiscal year (FY) 2013 appropriations are enacted.” The notice also states that “upward adjustments to awarded levels will be considered” after the FY 2013 funding levels have been resolved. The notice is available here.
Every year Congress must pass appropriations bills by October 1 to keep the federal government funded and running. However, it has become common practice to miss the October 1 deadline. This forces Congress to pass a Continuing Resolution which allows the federal government to keep running, but at a bare-bones minimum. This notice of reducing grants is consistent with NIH’s practice that was in effect during the Continuing Resolutions between FY 2006 and FY 2012.
It is expected that Congress will pass the remaining appropriations bills sometime after the elections during the "lame-duck" session of Congress. However, if an agreement on the appropriations bills cannot be reached during the "lame-duck" session, it will be up to the new Congress to pass the bills sometime next year. The current Continuing Resolution expires on March 27, 2013. More

Early Research Shows Exercise Boosts Immunity to Fight Off Cancer
New York Daily News
Researchers from the University of Nebraska found that when cancer survivors exercise for several weeks after they finish chemotherapy, "their immune systems remodel themselves to become more effective, potentially fending off future incidences of cancer."
A new preliminary study announced Wednesday finds that exercise may boost the immune system to protect against future cancers. More
Short Bursts of Exercise Can Burn Calories throughout the Day
Although we all need it—maintaining a regular exercise regimen can be difficult with the demands of everyday life pulling at us from every direction.
However, some exercise is better than none at all and a new study from a group of Colorado researchers supports that notion by demonstrating a few short bursts of intense exercise can burn to up 200 more calories throughout the day. More
