Active Voice: How much exercise is needed to improve insulin resistance?
By Francesca Amati, M.D., Ph.D.    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.

Dr. Amati is a research group leader in the Department of Physiology at the University of Lausanne, Switzerland. Specialized in internal medicine with a research background in exercise physiology, her main research focuses on insulin resistance and the mechanisms by which physical activity prevents or treats chronic diseases such as diabetes. This commentary presents Dr. Amati’s views associated with the research article she and her colleagues published in the May 2012 issue of ACSM’s Medicine and Science in Sports and Exercise® (MSSE).

Regular exercise is one of the first lines of defense against type 2 diabetes (T2D). Insulin resistance is a key component of T2D and is often present for many decades before the onset of T2DM. While some cross-sectional and prospective intervention studies have demonstrated the beneficial effect of endurance exercise on the improvements of insulin resistance in healthy and pre-diabetic states (such as impaired glucose tolerance), other studies report contradictory results with either no effect of exercise on insulin sensitivity or the observation of an effect only if performed at relatively high intensity.

Beyond the current recommendations to engage in at least 150 minutes of moderate-intensity endurance exercise each week (see ACSM Position Stand, for example), unanswered questions with important clinical and practical questions remain. Some examples are: “Will a sedentary person obtain improvements in insulin sensitivity if exercising less then 150 min/week?”, “Will the gain be proportionally greater if exercising more?”, and “Will someone with a high degree of insulin resistance respond better then someone with a relatively lower insulin resistance?” Our recent study in MSSE was conducted to examine the dose-response effect of exercise on improvements in insulin sensitivity during physical training in previously sedentary adults.

Policy Corner: NIH Issues Reports Relating to Biomedical Research
Share   Share on FacebookTwitterShare on LinkedinE-mail article
On June 14, three reports with major implications for biomedical research were released: The National Research Council (NRC) report on research universities: Research Universities and the Future of America: Ten Breakthrough Actions Vital to Our Nation's Prosperity and Security, the draft summary of National Institutes of Health (NIH) Advisory Committee to the Director (ADC) biomedical research workforce report, and the draft report of the NIH ADC working group on diversity.

The Federation of American Societies for Experimental Biology has provided a brief summary of the reports for members of FASEB constituent societies, including ACSM.

ACSM releases report on UN Side Event on Physical Activity and NCDs
Share   Share on FacebookTwitterShare on LinkedinE-mail article
This report provides an overview of the Side Event on Physical Activity and NCDs, which took place September 18, 2011, in front of the UN High-level Meeting on Non-Communicable Diseases, in New York City. The Side Event was organized by the American College of Sports Medicine, in partnership with Wellness Week organizers (the Pan American Health Organization and the World Economic Forum), the CDC/WHO Collaborating Center for Physical Activity and Health, and the President’s Council on Fitness, Sports & Nutrition. United by a shared conviction about the role of physical activity and sports in contributing to healthy people and heath-enabling environments, the Side Event drew the U.S. Surgeon General, national ministers of health, Olympic athletes, delegates to the U.N. High-Level Meeting, and leaders from nonprofit organizations, philanthropies, governments and business.

The Side Event focused on five pillars:
  1. Leadership: Ministerial Dialogue on Physical Activity and the “Americas.” Opening dais of ministers of health and/or their representatives from Aruba, Brazil, Colombia, Peru, and the United States, discussed the “state of physical activity” in national policy and planning processes.
  2. Awareness-Raising: Sports, Culture and Society. A panel composed of world-champion and Olympic athletes documented the power of sports and fitness in improving their individual lives and in mobilizing mass populations to better health.
  3. Collaboration: Physical Activity as a Best Buy in Advancing Towards a Healthier World. Senior officials from business, public health, academia, development, and patient interests came together to showcase the possibilities of physical activity and sports in achieving thematic multi-sectorial goals.
  4. Innovation and Adaptability: Getting the ROI on Physical Activity. A showcase of programs that scaled physical activity through the schools, worksite, grassroots sports, and primary care platforms.
  5. Taking Action: Questions were posed to attendees for future follow-up, including:
      a. International Level Action: What do we need to do to inform the setting of targets and to prepare for 2012?
      b. National Level Action: What needs to be done to get physical activity/NCD priorities into national health and development plans?
      c. Evidence Base: What critical areas of research—especially implementation research—do we need in order to position physical activity and NCDs for future integration into development goals?
      d. Missing in Action: Are there issues that were poorly served in the Political Declaration?
      e. Working with Different Sectors: What are the specific issues we need to attend to in developing partnerships, including with the private sector?
