Active Voice: Inactivity Causes Excess Body Fat — Or Is the Reverse True?
By Kathleen F. Janz, Ed.D., FACSM, and Soyang Kwon, Ph.D.    Share    Share on FacebookTwitterShare on LinkedinE-mail article
Viewpoints presented in SMB commentaries reflect opinions of the authors and do not necessarily reflect positions or policies of ACSM.

Kathleen F. Janz, Ed.D., FACSM, is Professor in the Department of Health and Human Physiology at the University of Iowa in Iowa City. Her research interests include quantification of physical activity and fitness and examining the influences of these factors on health status, particularly in children. Soyang Kwon, Ph.D., is a post-doctoral scholar in the Department of Health Studies at the University of Chicago. Her research focus is the epidemiology of physical activity. In the Mar. 2011 issue of Medicine & Science in Sports & Exercise® (MSSE), Dr. Janz, Dr. Kwon and their coauthors published a related research paper entitled “Effects of Adiposity on Physical Activity in Childhood: Iowa Bone Development Study.”

Given the health consequences for individuals and the economic burden of health care for society, the lack of physical activity and increased prevalence of obesity are major areas of interest for researchers, health practitioners and the public. There is substantial evidence that both the lack of physical activity and the rise in obesity contribute to poor health, independently of and synergistically with each other.

Physiologically, it makes sense that the lack of physical activity contributes to adiposity accumulation. Many epidemiologic studies have also shown the effect of inactivity on obesity phenotype. However, the role of adiposity on physical activity participation (reverse causation hypothesis) has been investigated less often. Understanding the potential effects of adiposity levels on physical activity has significant implications for designing physical activity intervention programs, even those not specifically aimed at preventing or reducing obesity. The reverse causation hypothesis implies a positive feedback loop, where becoming obese leads to physical inactivity which leads to becoming more obese – a pattern that may continue throughout life. The consequences of this loop could be particularly devastating for children due to the strong tracking of adiposity and the critical formation of attitudes, values and motor skills that takes place during childhood.

Actiheart - Ambulatory Energy Expenditure Monitor

The Actiheart is the gold standard for ambulatory measurement of energy expenditure, having been validated against DLW. Combining activity and heart rate measurement in one discreet unit, it is possible to measure AEE in daily living for up to 21 days. The Actiheart can also record HRV data.

Minneapolis-St. Paul Tops 2011 ACSM American Fitness Index™

For the first time, Minneapolis-St. Paul is the healthiest, fittest metropolitan area in the United States, according to the ACSM American Fitness Index™ (AFI).

The 2011 AFI data report was released yesterday, evaluating the 50 most populous metropolitan areas in the country. Minneapolis-St. Paul-Bloomington edged out previous winner Washington, D.C. for the top spot with a score of 77.2 (out of 100 possible points). While Minneapolis-St. Paul and Washington D.C. (respectively ranked three and one in 2010) both improved their scores this year, the Twin Cities took the lead thanks to greater improvements in healthy behavior measures and a reduction in the percentage of smokers.

The rankings were profiled in a multi-page spread in the June issue of SHAPE magazine and a feature in yesterday’s USA Today, among other media outlets. Hear what others are saying about the ACSM American Fitness Index in this video.

“A regular, scientific evaluation of the infrastructure, community assets, behaviors and opportunities which encourage healthy and fit lifestyles is imperative for cities wishing to provide a high quality of life for residents,” said Walter Thompson, Ph.D., FACSM, chair of the AFI Advisory Board.

Indianapolis-based WellPoint Foundation awarded the AFI program a $171,800 grant last month to continue growth of several key programmatic elements. Funding will support the annual data report, a new technical assistance program for low-ranking metro areas, an application tool for smaller communities requesting guidance on data indicators that make a healthy community, and goals and objectives to guide communities in their program planning and implementation.

Policy Corner: Must-See Policy Sessions in Denver
Share   Share on FacebookTwitterShare on LinkedinE-mail article
Advocates for state concussion laws have much to celebrate (see Policy Corner, May 17.) But, how can we organize to pass similar bills in other states? What else is on ACSM’s policy agenda, and how can we advance it in an intensely political climate?

Don’t just ponder, fret and opine – catch up on the situation, brush up your advocacy skills and help make it happen. If you’ll be at the 58th ACSM Annual Meeting and the 2nd World Congress on Exercise is Medicine® in Denver, here are two sessions you won’t want to miss:
  • Advocacy 101
    Friday, June 3 from 12:00 – 12:50 p.m.
    Rm. 203, Colorado Convention Center
    James Brown, vice president for federal relations with Bose Public Affairs Group, lays out the basics and beyond in a session of interest to advocates of all levels of experience. Whether you’re just considering getting involved in local issues or have spent quality time on Capitol Hill, this hands-on session will leave you ready to seek policy changes that can make a difference for your profession and your community.

  • Health & Science Policy Symposium
    Saturday, June 4 from 9:00 – 11:00 a.m.
    Rm. 504, Colorado Convention Center
    Join us immediately following the Dill Lecture for an annual highlight with extra relevance this year. Stephen Rice, M.D., Ph.D., FACSM, will chair this session, featuring updates on four of ACSM’s top policy priorities – concussion in youth sports, implementing the National Physical Activity Plan, physical activity guidelines legislation and Exercise is Medicine legislation. Geoffrey Moore, M.D., FACSM, will moderate.

Can't Move Your Muscles?
Los Angeles Times    Share    Share on FacebookTwitterShare on LinkedinE-mail article
Post-workout euphoria can leave you feeling pumped to conquer the world — until the next morning, when you can barely walk to the bathroom or lift an arm to brush your teeth.

Such are the painful rewards of delayed onset muscle soreness, or DOMS, a result of microscopic tears to muscle fibers that occur when you run faster, lunge deeper, crunch harder or lift more than usual. The damage ignites an inflammatory response as the muscle repairs itself, causing pain that peaks 24 to 48 hours after the activity and dissipates in five to seven days, said Carol Torgan, a health consultant and fellow with the American College of Sports Medicine.

Fat's "Master Switch" Found — Could We Turn It Off?
MSNBC    Share    Share on FacebookTwitterShare on LinkedinE-mail article
Scientists have found that a gene linked to diabetes and cholesterol is a "master switch" that controls other genes found in fat in the body, and say it should help in the search for treatments for obesity-related diseases.

In a study published in the journal Nature Genetics, the British researchers said that since fat plays an important role in peoples' susceptibility to metabolic diseases like obesity, heart disease and diabetes, the regulating gene could be target for drugs to treat such illnesses.
