ACSM in the News: Stories Making Headlines

Active Voice: Physical Activity, Metabolism and Brain Morphology in Twins
By Urho Kujala, M.D., Ph.D.

Viewpoints presented in SMB commentaries reflect opinions of the authors and do not necessarily reflect positions or policies of ACSM.

Urho Kujala, M.D., Ph.D., is a specialist in sports and exercise medicine and professor at the Department of Health Sciences, University of Jyväskylä, Finland. His research focuses on different health benefits and adverse effects of sports and exercise. He has been a member of ACSM for 25 years.

This commentary presents Dr. Kujala’s views on the topic of a research article which he and his colleagues published in the March 2015 issue of
Medicine & Science in Sports & Exercise® (MSSE). This research study also was covered in a recent article in The New York Times.

In exercise science, long-term intervention studies are challenging to accomplish, and observational follow-up studies, even in a longitudinal setup, also present problems in establishing cause and effect relationships. A monozygotic (MZ) twin-pair co-twin control study design presents a highly effective means to establish controls for genetic predisposition and largely controls for childhood home environment.

In our co-twin control study (part of the FITFATTWIN study), recently published in MSSE, we investigated how physical activity level is associated with body composition, glucose homeostasis and brain morphology in young adult male MZ twin pairs – pairs that have been discordant for physical activity during the past three years. Identifying MZ co- twins who have long-term discordance in their physical activity habits is challenging because participation in physical activity has a rather high heritability.

ACSM Plays Leadership Role at Obesity Roundtable in Washington, D.C.

IOM Obesity Roundtable Members at the iconic
Einstein statue that is part of the National
Academy of Sciences in Washington, DC.
Numerous ACSM members including Russ Pate, John Jakicic, Jim Sallis, Abby King, and Nico Pronk presented and deliberated at a thought-leading innovation workshop as part of the Institute of Medicine Roundtable on Obesity Solutions last week in Washington, D.C. ACSM is a key member of the IOM Roundtable. The workshop overviewed and explored the state of science of the effects of physical activity on overweight and obesity and overall health in children and adults. The workshop also focused on transformative policy, community, technological and institutional strategies for promoting physical activity among children and adults. A summary and report of the workshop will be produced and the results will be translated into community and national strategies. Video from the conference is available on the IOM website.

ACSM Rallies Multi-organizational Support for Increased Physical Activity Research at NIH; Inclusion of Exercise in the NIH Common Fund a Top Priority
This week, ACSM led an effort to support NIH Funding for a new research focus area studying benefits of physical activity within the National Institutes of Health's Common Fund. ACSM submitted a letter to NIH Director Francis Collins in support of funding for this new area of research, which was supported and signed by 28 other societies and organizations.

ACSM feels that targeted use of federal resources to support high-impact research in areas of emerging scientific opportunity in biomedical science is a crucial endeavor for the progress of society and human well-being. Physical activity induces myriad biological responses and adaptations critical to the prevention and treatment of numerous diseases, yet the molecular and cellular mechanisms underlying those health benefits are largely unknown. Given the impact of physical activity on human health, the biomedical discovery potential of a dedicated effort is undeniable.

8 Women Made History at Boston Marathon in 1972 —14,000 Registered in 2015 Race
The Huffington Post
Editor's note: ACSM has worked with Kathrine Switzer, who was a keynote speaker at a previous ACSM Health & Fitness Summit.

Please note: The Huffington Post ads and suggested links adjacent to this article may be provocative and risqué.

On April 19, 1967, Kathrine Switzer, 20, a journalism major at Syracuse University, entered the Boston Marathon as "K.V. Switzer," wearing a bulky sweatsuit. At the time, the Amateur Athletics Union (AAU) did not admit women into marathons. Switzer became the first female to officially enter and run. The photo of a race official forcibly attempting to stop her and grabbing for her race numbers was the photo shot heard round the world. Life magazine listed the photo as one of the "100 Photographs That Changed The World."

Switzer was determined to cross the finish line, despite blistered and bloodied feet. She had to wear men's athletic shoes she had ordered from Europe. Quite a feat! Athletic shoes for females were not yet manufactured because there was not a large enough market.

The AAU did not formally accept females in long-distance running until the fall of 1971. Women officially started to compete in the Boston Marathon in 1972. That was the same year Congress passed Title IX, Ms. Magazine was launched and Helen Reddy's "I Am Woman" topped the charts. Billie Jean King was named the first Sports Illustrated Sports Woman of the Year in 1972.

Nina Kuscsik's 1972 victory made her the first official Boston Marathon female champion in its 74-year history. That year eight females started the race and all eight finished. Kuscsik, 33, was the mother of three children under age six. Since the first eight women were officially entered and finished the Boston Marathon and groundbreaking Title IX legislation was passed, women's participation in long-distance events has grown and boomed.

What's the Perfect Amount of Exercise for a Longer Life?
Editor's note: this article references the 2008 Physical Guidelines for Americans, which ACSM helped develop.

When it comes to exercise, less is not more — but more is not more, either. According to new research published in JAMA Internal Medicine, there's a sweet spot for exercising just enough for a long life. It's probably no surprise to you that exercise is good for your body and well-being. For some time, though, the question has been: how much is best? Current guidelines suggest 150 minutes of moderate-intensity workouts per week for optimal health. Two new studies have popped up recently examining the effects of physical activity on lifespan, placing that number under the microscope.

The first and largest study from the National Cancer Institute and Harvard University rounded up exercise data from 661,000 middle-aged adults through surveys. Researchers placed the amount of exercise along a spectrum, from those who were virtually sedentary to those who exercised in excess of 25 hours a week.

Those who didn't work out were at highest risk of death. Those who exercised lightly, but below current recommendations, dropped their risk of an early demise by 20 percent over the 14-year study period, when compared to nonexercisers. The rule-followers who hit the 150-minute mark exactly saw a 31 percent reduced risk of death.
