Active Voice: Using the Latest Exercise Guidelines for Type 2 Diabetes to Halt the Epidemic
By Sheri R. Colberg, Ph.D., FACSM
Viewpoints presented in SMB commentaries reflect opinions of the authors and do not necessarily reflect positions or policies of ACSM.
Sheri R. Colberg, Ph.D., FACSM, is a professor in the Human Movement Sciences Department at Old Dominion University in Norfolk, Virginia. Her research has focused on the benefits of exercise training in type 2 diabetes. See the Dec. 2010 issue of Medicine & Science in Sports & Exercise® for the joint position statement, "Exercise and Type 2 Diabetes," for which Dr. Colberg chaired the writing group.
The U.S. is being overwhelmed by gloomy projections of a rapid rise in cases of diabetes mellitus. Recently, the Centers for Disease Control and Prevention predicted that one of every three Americans will have diabetes by 2050. Moreover, more than half of Americans may develop diabetes or prediabetes – putting them at high risk of developing type 2 diabetes – within the next ten years, according to a new report by health insurer UnitedHealth Group. UnitedHealth Group also projected that diabetes and prediabetes together will account for ten percent of total health care spending by 2020, with an annual cost of almost $500 billion and a total cost of $3.35 trillion over the next decade.
Can anything be done to prevent or reverse the impending diabetes tsunami that is threatening not only the U.S. but also the world? The latest evidence-based research on physical activity and type 2 diabetes – reported in a newly-released joint position statement by ACSM and the American Diabetes Association – unequivocally shows that regular exercise plays a major role in preventing and controlling insulin resistance, prediabetes, type 2 diabetes, gestational diabetes mellitus and costly diabetes-related health complications.
Admittedly, much of the information in this joint position statement is not entirely new; in fact, it reiterates that both aerobic and resistance training improve insulin action, at least acutely, and can improve blood glucose levels, lipids, blood pressure, cardiovascular risk, mortality and quality of life. What is newsworthy, however, is the recommendation that individuals with type 2 diabetes get at least 150 minutes a week of moderate-to-vigorous aerobic exercise spread out at least three days during the week, with no more than two consecutive days between bouts of aerobic activity.More

Policy Corner: NIH to Create Translational Science Center
The National Institutes of Health (NIH) announced last week that they are moving forward with a plan to create a new center focused on translational science. NIH Director Francis Collins called the decision “a momentous occasion” and projects that creating the center could be completed in about one year.
The center, which was proposed by NIH’s Scientific Management Review Board (SMRB – a panel established by the 2006 NIH reauthorization bill), would comprise the Clinical and Translational Science Awards program (currently part of the National Center for Research Resources), along with translational research and resources programs such as the Molecular Libraries Program, Therapeutics for Rare and Neglected Diseases, Rapid Access to Interventional Development, NIH-FDA partnerships and the recently created Cures Acceleration Network. Creating this center was recommended by the Translational Medicine and Therapeutics (TMAT) working group, a subset of SMRB that includes seven directors and senior members of the scientific community.

Give the Gift of Mentoring to Exercise Science and Sports Medicine Students
Are you interested in helping guide future leaders in sports medicine and exercise science? ACSM has launched a new member benefit, where members can sign up to mentor a sports medicine or exercise science student on MentorNet. Become a mentor today!
MentorNet is a web-based e-mentoring program which matches ACSM members with university students pursing careers in sports medicine and exercise science. To date, more than 65 ACSM members have taken advantage of this rewarding volunteer opportunity and have been matched to mentees. Spend as little as 15 minutes per week for eight months guiding future leaders in your field. View frequently asked questions.
Students – do you have questions about your future career or graduate school? Are you looking for ways to network? An ACSM mentor can help! Click here to sign up for a mentor. More
16 Minutes of Exercise Separates Fit, Unfit Kids
Normal-weight children get 16 more minutes of physical activity a day than their obese peers, a new study shows. And overall, girls do 20 minutes less physical activity a day than boys.
"This is a huge wake-up call to society," says Donna Spruijt-Metz, the senior author of the study and an associate professor of medicine at the University of Southern California.
A third of American children are overweight or obese. The government's physical activity guidelines recommend that kids and teens get an hour or more of moderate-intensity to vigorous aerobic physical activity a day. More
School Sports Concussion Safety Bill Signed Into Law
New Jersey Today
Editor’s note: ACSM, a prominent advocate for appropriate laws and policies on concussion in youth sports, applauds the passage of concussion legislation in New Jersey. On its own behalf and as a leader of a coalition of organizations, ACSM continues to work toward passage and implementation of effective concussion laws in every state and in the U.S. Congress.
A bill which will make New Jersey the state with the most comprehensive concussion prevention and treatment law in the country was signed into law Tuesday at a ceremony at the new Meadowlands Stadium.
“When it comes to New Jersey’s student athletes, we all have a responsibility to make sure their sport is as safe as possible,” said Senator Joseph Vitale, D-Middlesex. “This new law represents common sense solutions when dealing with head trauma, to make sure that the player doesn’t aggravate the injury by returning to the field too soon. It ensures that school officials, coaches and parents have the information they need to make the best choices for their children’s health.”More
Weight-Lifting After Breast Cancer Won't Cause Lymphedema, Study Finds
Contrary to conventional wisdom, lifting weights doesn't cause breast cancer survivors to develop the painful, arm-swelling condition known as lymphedema, new research suggests. There's a hint that weight-lifting might even help prevent lymphedema, but more research is needed to say that for sure, the researchers said.
Breast cancer-related lymphedema is caused by an accumulation of lymph fluid after surgical removal of the lymph nodes and/or radiation. It is a serious condition that may cause arm swelling, awkwardness and discomfort.
"Lymphedema is something women really fear after breast cancer, and the guidance has been not to lift anything heavier even than a purse," said Kathryn H. Schmitz, lead author of the study to be presented Wednesday at the San Antonio Breast Cancer Symposium. More
