Active Voice: Gender Differences in the Marathon —Nature or Nurture?
By Sandra Hunter, Ph.D., FACSM    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.

Sandra Hunter, Ph.D., FACSM, is Associate Professor in the Exercise Science Program, Department of Physical Therapy at Marquette University in Milwaukee. Her research focus includes understanding the mechanisms for sex and age differences in motor control and neuromuscular fatigue and the added impact of psychological stress. In the April 2011 issue of Medicine & Science in Sports & Exercise® (MSSE), Hunter and co-authors published a related research paper entitled “Is There a Sex Difference in the Age of Elite Marathon Runners?”

In 1992, a controversial article in Nature projected, based on improvements in running times from previous decades, that women would outrun men in the marathon by 1998. This did not occur because the physiological differences between elite men and women runners still exist. Men, on average, have less body fat, larger hearts and greater hemoglobin concentration than women, facilitating larger maximal oxygen consumption and faster marathon times (for more, see article by Michael Joyner). In a recent article in MSSE, we highlighted the sex differences in the age and performance of elite marathon runners. The findings offer a glimpse into sex differences in physiology and other sociological factors that affect performance.

USOC Hosts 2nd Annual Sports Medicine Symposium on Concussion
Share   Share on FacebookTwitterShare on LinkedinE-mail article
ACSM continues to get results (and recognition) for its ongoing efforts to help pass state laws governing concussion in youth sports. Partnerships, such as with the NFL and the member organizations of the National Coalition on Youth Sport Concussion, are essential to such widely based efforts. Another partnership of great significance for ACSM and its members is with the U.S. Olympic Committee. There is a high level of congruence in the two organizations’ missions, including athlete health and safety.

The U.S. Olympic Committee invites ACSM members to attend their 2nd annual sports medicine symposium, “Exploring Concussions Head On: Current Concepts.” The symposium will be held July 23, 2011 from 8 a.m. to 6 p.m. at the U.S. Olympic Training Center in Colorado Springs. With sports-related concussion so strongly relevant for both its clinical and policy considerations, many ACSM members are likely to find this event of interest.

Utilizing a collaborative approach, this symposium provides an in-depth look at concussions in sport. This unique approach will encourage health care providers to work together across disciplines to provide the best care possible to the patient. This course will give the attendee a look at some of the most advanced evaluation and treatment techniques for concussion injuries. Nine CEUs will be available for this course.





ACSM Members Save 10% on Preventing Sudden Death in Sport and Physical Activity
Share   Share on FacebookTwitterShare on LinkedinE-mail article
Published in cooperation with ACSM, Preventing Sudden Death in Sport and Physical Activity examines the etiology, prevention, recognition, treatment and return-to-play protocol of the common causes of sudden death in sport. Highlights of the book include:
  • Cardiac conditions are separated into three chapters to give greater attention to the multiple potential etiologies related to cardiac causes.
  • For the first time in a sports medicine textbook, exertional sickling is offered as a standalone chapter.
  • Another chapter covers anaphylaxis, cold, diabetes and issues in wilderness medicine situations.
  • Supporting chapters focus on issues that can influence the infrastructure to prevent sudden cardiac death during sport and physical activity.

Policy Corner: Out of the Ivory Tower
   Share    Share on FacebookTwitterShare on LinkedinE-mail article
While some scientists might prefer to conduct their research in a quiet laboratory, undisturbed by the clamor of a fractious and baffling society, none are removed from the implications of the many intersections of science and public policy. ACSM members likely are aware that the College is a member of the Federation of American Societies for Experimental Biology (FASEB), whose activities include pursuing a robust public policy agenda.

Helping make order out of the chaos that often pervades the science/policy nexus are a number of websites, including those of the Center for Science and Technology Policy Research and the American Association for the Advancement of Science. One hot topic being explored by both organizations is the current debate about climate change among policy makers, media and the public.

Double Your Impact with a Gift to Lisa Krivickas Travel Award
Share   Share on FacebookTwitterShare on LinkedinE-mail article
Through the end of the year, gifts to the Lisa Krivickas Travel Award go twice as far. At the Josephine L. Rathbone Memorial Breakfast during this year’s Annual Meeting, the ACSM Foundation announced a $2,500 matching gift challenge by ACSM Past-President, Angela Smith, MD, FACSM for donations made to the Krivickas Award before Dec. 31, 2011. If the fund raises $2,500 by the end of the year, all money will be matched dollar-for-dollar by Dr. Smith. Give online.

The Lisa Krivickas Travel Award, named after a ground-breaking neuromuscular disease researcher, funds travel to the ACSM Annual Meeting for a female clinician scientist. Part of Dr. Krivickas’s legacy is courageously volunteering to be the first ALS patient to use a novel treatment and advancing ALS treatment by many years. Read more about the fund.

A Little Bit of Exercise Makes a Big Difference
USA Today    Share    Share on FacebookTwitterShare on LinkedinE-mail
article
Lazy Americans, you are not off the hook, but health experts are cutting you some slack.

"It's very clear that a little bit of exercise makes a big difference," says Carol Ewing Garber, author of the American College of Sports Medicine's new guidelines on quantity and quality of exercise for adults. "The recommendation to get 150 minutes a week of moderate-intensity exercise is still one of the goals, but the message needs to be heard that doing less is also helpful."

Your New Exercise Rx from the American College of Sports Medicine: Get Out of That Chair and Move
Los Angeles Times    Share    Share on FacebookTwitterShare on LinkedinE-mail article
New exercise guidelines released by the American College of Sports Medicine Tuesday may be more detailed than the last, but don't worry -- the overriding message is that pretty much any kind of activity is better than sitting on the sofa.

Thanks to copious new research the guidelines, last updated in 1998, got an upgrade. The 150-minute or more per week rule for cardio is still there, as is information on strength training. Perhaps the biggest change is the relaxing of stringent exercise guidelines, says Carol Ewing Garber, ACSM vice president and associate professor of movement science at Columbia University. The previous approach emphasized reaching goals for cardio and strength training, a la, "You must do this or you won't improve your fitness and health," Garber says. Sure, it would be great for people to reach those goals every week, but that probably won't happen. "Research now supports the fact that you can do less than what's recommended and still get benefits. Your weight may stay the same, but your overall health may improve."

Ease Office Neck Pain with Two Minutes of Daily Exercise
USA Today    Share    Share on FacebookTwitterShare on LinkedinE-mail article
If you work in an office, keeping neck and shoulder pain away may only take two minutes a day.

A new study presented at the World Congress of the American College of Sports Medicine (ACSM) in Denver found that office workers doing two minutes of exercise a day reported lower levels of neck and shoulder pain after 10 weeks.

The study by Danish researchers involved 198 office workers who had frequent neck and shoulder pain but were otherwise healthy. The workers did either a 2-minute or a 12-minute resistance exercise using elastic tubing. The exercise was a lateral raise, in which the upper arm is raised until it is horizontal and the arms are 10 to 15 inches from the body, says Lars Andersen, the lead researcher.
