Active Voice: Exercise or Calorie Restriction to Lower Blood Triglycerides Levels?
By Labros S. Sidossis, Ph.D., and Elena Bellou, Ph.D.
Viewpoints presented in SMB commentaries reflect opinions of the authors and do not necessarily reflect positions or policies of ACSM.

Labros Sidossis, Ph.D., is professor of medicine and nutrition and metabolism at the University of Texas Medical Branch (UTMB), Galveston, USA. A member of ACSM, he is Director of Obesity Research at the Sealy Center on Aging at UTMB. Dr. Sidossis also is Professor in the Department of Nutrition and Dietetics, Harokopio University, Athens, Greece. His research interests include obesity and lipid metabolism, lifestyle interventions to promote health and brown adipose tissue metabolism.

Elena Bellou, Ph.D. is clinical dietitian and post-doctoral fellow in the Department of Nutrition and Dietetics, Harokopio University, Athens. Her scientific interests relate to the regulation of human lipid metabolism, particularly effects of lifestyle interventions on lipoprotein triglyceride kinetics.

In this commentary, Dr. Sidossis and Dr. Bellou present their views related to the research report which they and their colleagues published in the March 2013 issue of
Medicine and Science in Sports and Exercise® (MSSE).

Lifestyle changes are the first line of therapy for metabolic abnormalities such as hypertriglyceridemia, or elevated triglycerides. Exercise is particularly efficient in improving the lipid profile in humans; even a single bout of exercise can acutely decrease the blood triglyceride concentration. However, for this to work, exercise should result in a negative energy balance. When food is increased to compensate for the energy lost during exercise, the hypotriglyceridemic effect of exercise is lost.

Still Time to Register for Every Body Walk! 2013 Walking Summit

Walking is a natural, yet profound act. We were born to walk. Fortunately, most of us are able to walk (or roll). Indeed, there is no simpler, more joyous, free activity we can engage in that contributes so significantly to improving our physical and mental health. There's still time to register for the Every Body Walk! 2013 Walking Summit in Washington, D.C., October 1-3, which will address issues like creating more walkable places, developing safe walking routes to school, work (see more at www.everybodywalk.org). The event is happening at the Renaissance Washington, D.C. Downtown Hotel and the Kaiser Permanente Center for Total Health.

Here are a few details of the 2013 Walking Summit:
  • Purpose – Advance the vision of Every Body Walk! to get Americans moving through building the demand for walking, and increasing the supply of safe places to walk.
  • Who should attend – Business, government, elected officials and staff, nonprofit, advocacy, faith and community/grassroots – across these sectors: health care, public health, workforce wellness, economic development and place-making, education, environment, equity, media, planners from open space/parks/recreation/transit, civic and faith associations, community improvement collaborations, engineers and others with a stake in healthy people and vibrant places.

Policy Corner: Open Streets – Bringing Advocacy to your Neighborhood

Here's policy work at its most pleasant: Walking, cycling, rolling, dancing, playing and socializing with your neighbors at an Open Streets event. Long the rage in Latin America, where they're called "ciclovías," Open Streets initiatives temporarily close portions of roadways to automobile traffic. Participants enjoy the physical activity, entertainment, vendors and personal interaction, perhaps unaware that they're contributing to social, economic and public health goals.

ACSM is a strong supporter of Open Streets initiatives, including the first one to be held Sept. 29 in Indianapolis, the college’s hometown (just before the 2013 Every Body Walk! Walking Summit – see above). Earlier this month, ACSM co-sponsored a national Open Streets training in Minneapolis for advocates, local government officials and business groups interested in planning Open Streets events in their communities. Robert Oppliger, Ph.D., FACSM, an avid bicyclist who chairs the Health & Science Policy Committee, was among participants from about 17 states. He reported that Minneapolis’ first Open Streets event, held in conjunction with the training, drew an estimated 8,000-10,000.

Open Streets initiatives are a clear, family-friendly embodiment of essential elements of numerous initiatives such as Every Body Walk!, ActivEarth (an initiative that will be launched in 2014 that emphasizes the connection between physical activity, environmental sustainability, and economic development), Designed to Move, and the National Physical Activity Plan. Learn more at http://openstreetsproject.org/-- and how about starting an Open Streets event in your community?

SPORTS MEDICINE & EXERCISE SCIENCE HEADLINES

Headlines include recent stories in the media on sports medicine and exercise science topics and do not reflect ACSM statements, views or endorsements. Headlines are meant to inform members on what the public is reading and hearing about the field.


Running May Actually Protect You Against Osteoarthritis
Anchorage Daily News
While out on a run recently, I passed a hiker on the trail. "My knees hurt just watching you," he told me, shaking his head. It was a variation on a comment I hear over and over: Keep running like that, and you'll give yourself arthritic knees.

The notion that running causes wear and tear on the joints that could spur arthritis makes some intuitive sense. But is it true?

No — if anything, running probably offers protection from osteoarthritis, says Paul Williams, an exercise scientist at Lawrence Berkeley National Laboratory who leads the National Runners' Health Study and the National Walkers' Health Study. These projects have enlisted almost 90,000 runners and walkers and followed them since the studies began, in 1991 and 1997, respectively. In an analysis recently published in the journal Medicine & Science in Sports & Exercise, Williams calculated rates of osteoarthritis and hip replacement among participants in his studies and found that runners were approximately half as likely as walkers to develop osteoarthritis or need a hip replacement. Furthermore, runners who ran the most had the lowest risk of osteoarthritis.

Extreme Workouts Part of a Growing Trend in Gyms
San Luis Obispo Tribune
The 15 women and one man are all steadily focused on the task at hand: survival.

This HIT - high-intensity training - class at FIT Studio in Lexington, Ky., is part of a national exercise trend.

While the idea of extreme fitness has been around for several years, it's recently come into more public view. Even the most slacking couch jockey is aware of the movement thanks to a seemingly never-ending techno beat of late-night commercials touting DVDs for such intense works outs as P90X and Insanity. P90X, which a promotional website describes as "sweat-inducing, muscle-pumping exercises designed to transform your body from regular to ripped," includes a 12-disc program and nutrition advice. The Insanity program is described at its home page, BeachBody.com, as "the world's most insanely tough work out." Submit a before and after picture to the company and you get a free "Insanity" T-shirt.
