Active Voice: Resistance Training in Healthy Older Adults — Do We Need to Supplement Dietary Protein?
By Lex B. Verdijk, Ph.D. and Luc J.C. van Loon, Ph.D.
Viewpoints presented in SMB commentaries reflect opinions of the authors and do not necessarily reflect positions or policies of ACSM.
Dr. Verdijk is a researcher and Assistant Professor at the Department of Human Movement Sciences at Maastricht University Medical Centre+, the Netherlands. His research focuses on the role of exercise and nutrition in the regulation of skeletal muscle mass and function, with special interest in the aging human.
Dr. van Loon is a Professor of Physiology of Exercise at the Department of Human Movement Sciences, Maastricht University Medical Centre+, the Netherlands. An ACSM member, Dr. van Loon leads the M3 Research Unit at Maastricht University. The main fields of investigation in his research unit include human skeletal muscle metabolism, exercise metabolism, sports nutrition, adaptation to endurance and resistance type exercise training, and the use of combined physical activity and/or dietary (lifestyle) interventions to improve health and/or functional performance in chronic metabolic disease (obesity and type 2 diabetes) and aging.
This commentary presents Dr. Verdijk’s and Dr. van Loon’s views on the topic of a research article which they and their colleagues published in the March 2013 issue of Medicine and Science in Sports and Exercise®, "Protein supplementation during resistance-type exercise training in the elderly."
Muscle mass, strength, and function progressively decline with increasing age. This process has been termed "sarcopenia", and ultimately results in physical disability, loss of independence, and reduced quality of life. Since both decreased physical activity and inadequate food intake play a key role in the development of sarcopenia, exercise and/or nutritional interventions are considered important tools in its treatment. Resistance type exercise training is currently regarded as the most effective intervention strategy to counteract loss of muscle mass and function with aging. Although several studies have suggested that protein supplementation may be of additional benefit, there is no clear evidence that elderly should combine resistance training with protein supplementation to optimize the effects of exercise. Inconclusive findings are likely caused by differences in the populations studied, the amount, type, and timing of supplements, and duration of the intervention programs.More

Policy Corner: Dr. Howard Koh of HHS Addresses Annual Meeting
Intense interest in Dr. Howard Koh's participation in the 60th ACSM Annual Meeting led to an overflow crowd for his May 31 session. Dr. Koh, who serves as Assistant Secretary for Health for the U.S. Department of Health and Human Services, spoke about physical activity as a public health priority and public policies to encourage healthy lifestyles. His session benefitted from a dialogue with his fellow physicians Elizabeth Joy, MD, FACSM, and Robert Sallis, MD, FACSM. Dr. Koh noted that he is a lifelong proponent of healthy lifestyles and appreciates the many co-benefits of physical activity for people of every age. Numerous questions from the audience signaled concurrence on the importance of this emerging public health priority.
In separate meetings with ACSM leaders, Dr. Koh indicated strong interest and appreciation for Exercise is Medicine and the National Physical Activity Plan and requested a briefing on those and other initiatives. He helped revive and bolster the President's Council on Fitness, Sports and Nutrition, for which numerous ACSM members serve as science advisors.
Dr. Koh expressed deep appreciation for the invitation to speak and enthusiasm for future collaboration between his office and ACSM.More
July 1 Funding Deadline Approaching: GE and NFL Head Health Challenge
GE and the National Football League are currently accepting proposals for technologies and imaging biomarkers that address identification and management of subclinical and mild traumatic brain injury.
GE and the NFL seek to address the current technical and scientific limitations in achieving better diagnosis of brain injuries and assessment of long-term chronic impact. For example, technological advancements are needed to develop and validate biomarkers that quantify disease severity and predict long-term outcomes from repetitive injuries. Better algorithms also are needed to identify and analyze subtle changes of morphology and function in the brain. A better understanding of the molecular, physiological and behavioral/biomechanical changes that occur shortly after a traumatic event is needed to reliably diagnose the types of changes that are difficult to identify using current technologies.
RESPONSE DUE DATE: July 1, 2013. Multiple awards with a cumulative value of up to $10 Million are available.

No Time? Work Out Like a 'Corporate Athlete'
Seven minutes. That's the amount of time it takes to complete the high-intensity circuit training program Chris Jordan designed to help his clients lose weight and get fit. Repeat the circuit two to three times and your workout is over.
You'll sweat. Your muscles will probably be sore the next day. And all you need is a small space on the floor, a chair and your own body weight.
"(High-intensity circuit training) is growing in popularity because of its efficiency and practicality for a time-constrained society," Jordan writes in the May/June issue of the American College of Sports Medicine's Health & Fitness Journal. "The combination of aerobic and resistance training in a high-intensity, limited-rest design can deliver numerous health benefits in much less time than traditional programs."
Jordan is the director of exercise physiology at the Human Performance Institute, where he developed the fitness programming portion of their Corporate Athlete program for business executives looking to improve their performance — in and out of the office.More
American Fitness Index 2013: Fittest Cities
The Huffington Post
How do you evaluate a city? If you're thinking of moving, you might look at school quality, commute times and real estate resale values. But here's another measure to keep in mind: Fitness.
For the fifth year in a row, the American College of Sports Medicine has ranked U.S. cities based on measures of health and health potential.
"As urban areas attract more and more residents, it's imperative for cities to create a built environment, fund amenities and form policies that get residents active and encourage healthy lifestyles," Walter Thompson, Ph.D., chair of the AFI Advisory Board said in a statement. More
