Active Voice: Assessing Body Composition and Visceral Fat in Obese Patients
Viewpoints presented in SMB commentaries reflect opinions of the authors and do not necessarily
reflect positions or policies of ACSM.
Ross Andersen, Ph.D., is an ACSM member and the Canada Research Chair in Physical Activity and Health at McGill
University in Montreal. His research focuses on helping seriously obese patients optimize changes in body
composition when they lose weight.
Tamara Carver, M.Sc., also is an ACSM member and a doctoral student in Dr. Andersen’s lab at McGill University. Her
work has focused on examining the precision of DXA technology in obese patient populations and tracking changes in
body composition that occur with large amounts of weight loss.
This commentary presents Dr. Andersen’s and Ms. Carver’s views related to a research report which they and their
colleagues authored and which appears in the July 2014 issue of Medicine & Science in Sports & Exercise® (MSSE).
Obesity is characterized by an excess of body fat. Over one-third of adults in the U.S. are now classified as obese
(CDC data). In addition, obese individuals often have lower
than expected levels of lean body mass. The accurate assessment of body composition may offer exercise scientists
important clinical information beyond what can be derived from simply calculating BMI. Understanding the percentage
of weight that is fat and metabolically active lean tissue may offer important insights into tailoring interventions
which promote fat loss and simultaneously attenuate the loss of fat-free mass. In addition, recent technology with
DXA scanners now can accurately quantify bone mineral density and visceral (hazardous) adipose tissue in obese
individuals.

September is Childhood Obesity Awareness Month
ACSM's shared concern over childhood obesity is well supported by data. More than 23 million children and teenagers in the U.S. are overweight or obese, according to recent measurements. In 2010, health and medical experts declared childhood obesity an epidemic. Also, while health consequences are concerning, the financial implications of childhood obesity are staggering. Obesity requires $14 billion per year for direct health care costs in the U.S.
Can you and your organization observe National Childhood Obesity Awareness Month and help spread the word? COAM is an informal advocacy movement of individuals and all types of organizations, drawing national attention to the childhood obesity epidemic that is a serious issue for U.S. youth. Across America, events and educational efforts throughout September will address the problem and offer solutions.
Thank you for considering how you can observe National Childhood Obesity Awareness Month and help all children enjoy the benefits of active, healthy lifestyles.
To access the 2014 COAM Month toolkit, click here.
A related opportunity of interest this month is a free, hour-long webinar on September 10 discussing the recently released U.S. Report Card on Physical Activity for Children and Youth, including a question and answer session with Drs. Katzmarzyk and Pate. Register now.

The Ways to Avoid Feeling Off During Workouts
The Wall Street Journal
One of the mysteries of being physically active is when the same workout feels great one week and lousy the next. Why does a routine 4-mile run or hourlong yoga class suddenly morph into the last leg of an Ironman triathlon?
Bad workouts happen to everyone, from professional athletes to office workers trying to carve out 30 minutes at the gym.
Coaches and academics can identify many factors to explain this mystery. In short, much of what you eat, drink and even think about can affect how you exercise.
Peter Thompson, a longtime track and field coach who has worked with athletic novices and Olympians, says one factor that can slow regular exercisers is inadequate recovery time.
"Training does not make you fitter. It's the recovery and adaptation for training that makes you fitter," says Mr. Thompson, a native Brit who lives in Eugene, Ore. "So you should train to recover, not recover to train."
Shape up at Home
Hanford Sentinel
If exercise were a pill, it would be one of the most powerful drugs ever invented, according to Consumer Reports.
Chances are, you've heard many variations of that sentiment. It's not hype. A 2010 review of 40 studies in the International Journal of Clinical Practice, for example, found that being active can help prevent about 25 conditions. Other research suggests that exercise can cut the risk of colon cancer by 60 percent, Type 2 diabetes by 58 percent, heart disease by 40 percent and Alzheimer's disease by 40 percent. Another study, which compared regular exercisers with couch potatoes, concluded that each minute of physical activity added an average of 7 minutes of life span.
Yet powerful evidence isn't powerful enough: Just 20 percent of Americans say they get the recommended amount of aerobic and strength exercise.
"Convenience and proximity are key predictors of exercise," says Dr. Carol Ewing Garber, associate professor of movement sciences at Columbia University and president elect of the American College of Sports Medicine. So it makes sense that working out at home ups the odds not only that you'll become active but also that you'll stick with a routine.
Consumer Reports consulted with experts to help you pick the machine that will best help you reach your health goals.
