ACSM in the News: Stories Making Headlines


Active Voice: Features of Prolonged Sitting Behavior Correlate with Cardiometabolic Disease Risk Markers
By Kate Lyden, Ph.D. and Sarah Kozey Keadle, Ph.D., M.P.H.
Kate Lyden, Ph.D. Sarah Kozey Keadle, Ph.D.
Viewpoints presented in SMB commentaries reflect opinions of the authors and do not necessarily reflect positions or policies of ACSM.

Kate Lyden, Ph.D., is a research scientist at the University of Colorado, Denver. Her research is funded by the NIH and examines the effects of interrupting sedentary time with short and continuous bouts of moderate intensity walking on metabolic outcomes in overweight adults. She has developed methodologies to quantify physical activity, sedentary behavior and sleep using wearable sensors and uses these techniques to understand the dose-response relationship between physical activity, sedentary behavior and chronic disease.

Sarah Kozey Keadle, Ph.D., M.P.H., is a cancer prevention fellow in the Division of Cancer Epidemiology and Genetics at the National Cancer Institute in Bethesda, Maryland. Her research broadly focuses on the relationship between physical activity, sedentary behavior and disease prevention, with a specific interest in improving measures of active and sedentary behaviors and applying novel methods to further our understanding of the associations between these behaviors and health risk.

This commentary presents Drs. Lyden’s and Kozey Keadle’s views on the topic related to a research article they authored with their colleagues and which appears in the May 2015 issue of Medicine & Science in Sports & Exercise® (MSSE).

ACSM Leadership Meets with U.S. Surgeon General
A group of ACSM leaders met with U.S. Surgeon General Vivek Murthy yesterday to discuss his upcoming Call to Action on Walking and Walkability. At the meeting, the group reviewed the nature, scope and concerns related to the obesity epidemic in the U.S., the science available on the benefits of walking and potential effective interventions. ACSM supports the call to action and its goal to mobilize individuals, organizations, communities and society to take immediate action to improve health by walking.

Attendees: ACSM President Larry Armstrong, EVP/CEO Jim Whitehead, President-elect Liz Joy, Past President Carol Garber, VP of Government Affairs Monte Ward and Tom Farrey of the Aspen Institute- Project Play

New Legislation Introduced to Establish Physical Activity Recommendations
Last Thursday, U.S. Senators Patty Murray (Washington) and Roger Wicker (Mississippi) introduced the Promoting Physical Activity for Americans Act, legislation that would establish physical activity recommendations for children and adults. The bipartisan legislation would call on the Department of Health and Human Services (HHS) to issue physical activity recommendations based on the latest scientific and medical evidence every 10 years. The bill also directs HHS, five years after the release of each set of recommendations, to update reports that highlight continuing physical activity issues.

Regular physical activity recommendations would complement the Dietary Guidelines for Americans, which were first released in 1980, and would ensure HHS continues the legacy of the Physical Activity Guidelines that were released in 2008. ACSM played a leadership role in the development of the 2008 guidelines and strongly supports this new bill, which will ensure that the guidelines remain current. ACSM has worked closely with Senator Wicker and Senator Murray to ensure that the legislation accomplishes its goal to get America active. In addition, ACSM will continue to lead supporters of the legislation to build a strong coalition devoted to passage of the bill.

ACSM Signs Partnership Extension with Sanford Health, NYSHSI
ACSM has announced its continued partnership with Sanford Health to continue building upon achievements of the National Youth Sports Health & Safety Institute (NYSHSI). An ACSM affiliate, NYSHSI encourages early introduction of diverse functional movements and activities that are healthy and fun. This approach serves as a catalyst for developing a critical foundation, capacity and enthusiasm for sustainable physical activity through childhood, adolescence and beyond.

NYSHSI urges all youth sports stakeholders to provide a positive and healthy environment for kids to enjoy sports. This includes having fun, learning sports skills and the rules of the game, and developing as capable and confident young athletes at any level. Residual effects include helping youth become healthy, fit, good citizens of the game and community, and performing well in all domains of life.

A number of resources are provided by NYSHSI that can be instrumental in helping communities and families make youth sports participation a sustainable and effective solution to encouraging lifelong physical activity, fitness and health:
  • YouTube Video ChannelParents, coaches, athletes and other youth sports stakeholders can access short video clips providing insight into youth sports issues
  • NYSHSI Healthy Youth Sports appOur FREE interactive mobile app available on iTunes/App Store and Google Play
  • NYSHSI Educational HandoutsAvailable from our resource section on

  • NYSHSI Seal of Best PracticesCommunity youth sports programs can show their commitment to safe and healthy youth athlete participation and development, and receive a Best Practices Partner certificate by agreeing to fulfill three essential elements
As NYSHSI continues to grow, so does the partnership with Sanford Health and the Sanford Sports Science Institute (SSSI) as they continue their complementary work to improve sports safety. A search is currently being conducted for a new executive director to oversee both NYSHSI and SSSI. ACSM extends its thanks to Michael Bergeron, Ph.D., FACSM, who served as the institute’s executive director for many years and will continue in an interim role until a successor is named. More information about the position can be found below.

Fitness Apps Data Reveals American Workout Habits, Most Active States
Millions of Americans are recording their workout routines and activities on apps that are giving fitness experts new insights into the habits of a logged-in population.

Data compiled by fitness and workout tracker apps, MyFitnessPal and MapMyFitness, show that California, Colorado and Washington are the U.S. states with the most active residents based on the length, frequency and type of exercise they recorded.

South Carolina, Delaware and North Dakota are at the other end of the spectrum in the ranking.

"Seven of our top 10 active states were western states," said Rebecca Silliman of MyFitnessPal, which analyzed information recorded by its 65 million users.

It combined its data with workout information from MapMyFitness' 25 million users to rank the states according to their diet, sleep and activity habits.

Silliman said the data, logged from January to December of 2014, came mostly from people aged 25 to 44. About 65 percent were women and 40 percent were men.

Tracking Down the Optimum Dose of Exercise
The Pharmaceutical Journal
Forget laughter. And maybe even drugs. Exercise is the best medicine, or so many doctors say.

No other medical intervention can influence overall well-being as positively as physical activity. Countless epidemiological and clinical studies have demonstrated this, and now public health agencies around the globe — including the World Health Organization (WHO), the UK Chief Medical Officer and the US Department of Health and Human Services — are recommending that adults do at least 150 minutes of moderate aerobic activity (that which maintains an increased heart rate) or 75 minutes of vigorous physical activity each week, or some combination thereof. An hour or more of daily exercise is suggested for children and adolescents.

These best-practice guidelines have been informed by a number of systematic reviews showing that a minimum threshold of aerobic activity leads to diverse benefits, including lowering the risks of heart problems, metabolic disorders, cancer, depression and other chronic diseases. Physical inactivity is estimated to be responsible for around 9% of premature deaths; eliminating this sedentariness could theoretically increase the life expectancy of the world’s population by around eight months.

"The evidence is overwhelming," says Gregory Heath, an exercise scientist at the University of Tennessee at Chattanooga. Exercise is "one of the least appreciated, underused therapeutic tools available to the human race."
