Active Voice: Repeated Eccentric Exercises Modify Human Muscle Proteome
By Bernard Rogister, M.D., Ph.D.
Viewpoints presented in SMB commentaries reflect opinions of the authors and do not necessarily reflect positions or policies of ACSM.
Bernard Rogister, M.D., Ph.D., is Professor of Biochemistry and Physiology in the Medical School at the University of Liège (ULg) in Belgium. As a neuroscientist, his main research focuses on several aspects of developmental neurobiology and stem cells. However, he also has begun collaborating with Jean Louis Croisier, Professor of Physiotherapy (ULg), in order to unravel the molecular mechanisms of muscle damage following eccentric contractions. This commentary presents Dr. Rogister’s views associated with the research article he and his colleagues published in the Dec. 2011 issue of Medicine & Science in Sports & Exercise® (MSSE).
Eccentric (lengthening) muscle contraction frequently induces delayed-onset muscle soreness (DOMS), characterized by muscle pain, impairment of muscle function, stiffness, swelling and reduced range of motion. DOMS typically sets in a few hours after the eccentric exercise and will subsist for a few days, delaying the training program and/or the athlete’s exercise rehabilitation protocol. Histological studies have demonstrated various forms of sarcomeric disruption and membrane leakage that were associated with the presence of creatine kinase in the blood. An intriguing effect is the repeated bout effect. When a muscle has been conditioned by prior eccentric contractions, the magnitude of changes in muscle damage markers after later eccentric contractions is attenuated, constituting a muscle adaptation process.

Policy Corner: Young Researchers, Young Advocates Tell Their Stories; So Should You
This week’s Policy Corner features a letter from Mary Woolley, president and CEO of Research!America, of which ACSM is a member.
The primary race continues, and we continue our drive to put research on the primary agenda. Shortly before the New Hampshire primary, the Concord Monitor published a touching and timely op-ed by former Research!America intern Emily Norton. Sadly, Emily recently lost her mom to cancer. She tells her story and suggests what voters can do to make medical research a higher priority during the elections. Policy makers have the power to make medical research a higher priority – it us up to us to make sure they get the message! As the candidates stump in South Carolina for the upcoming primary, voters want to know where Romney, Santorum, Paul and Huntsman stand on health research issues. Urge them to respond to our voter education questionnaire (former Speaker Gingrich already has) and pen your own op-ed! More
President's Council to Honor Deserving Individuals with Annual Awards
The President’s Council on Fitness, Sports and Nutrition – which many ACSM members serve through its science board – is seeking nominations for its lifetime achievement and community leadership awards.
The community leadership award is given annually to more than 50 individuals who improve the lives of others in his/her community through opportunities to engage in sports, physical activities, fitness or nutrition-related programs. The lifetime achievement award is given annually to a maximum of five individuals whose careers have greatly contributed to the advancement or promotion of physical activity, fitness, sports or nutrition nationwide. Applications for both awards are due Feb. 1, 2012.More
2012 Youth Sports Safety Clinic Grant Application Now Available
Safe Kids USA is now accepting proposals for its 2012 Safe Kids Youth Sports Safety Clinic Program. The 2012 Sports Safety Program will build on the successful launch of the Youth Sports Injury Prevention public awareness campaign and program, which Safe Kids USA and founding sponsor Johnson & Johnson initiated in 2010. The ultimate goal of the Safe Kids Youth Sports Safety Program is to provide youth coaches, parents and athletes with practical information and skills that will lower the risk of sports injuries, emergencies and illnesses that occur each year in America's youth athletes.
Up to 50 clinic grants, in the amount of $1,500, are available to Safe Kids USA coalitions and chapters. Please complete the entire application, and return it to Lindsay Hansen at email@example.com by Feb. 3, 2012.More
Is There a Public Health Role for Fitness Professionals?

Can More Push-Ups Mean Fewer Pills?
Exercise may be the single most effective thing you can do to stay healthy, but many people never hear their doctors mention it.
Regular, moderate exercise has been shown to protect against conditions ranging from diabetes to depression, from cancer to cardiovascular disease. Yet about half of Americans don't do it. Studies suggest that people are more likely to exercise -- to at least try it -- if following doctors' orders. But health-care providers maintain no established tradition of discussing these benefits with their patients, have no framework for assessing patients' fitness or recommending regimens and specialists.
Exercise Is Medicine is working to change that. The four-year-old initiative, organized by the Indianapolis-based American College of Sports Medicine (ACSM) along with the American Medical Association, aims to make exercise assessments and advice as standard a part of doctor's office visits as weigh-ins and blood-pressure checks.

Bobby Buttafuoco and Arm Wrestling's Pull
Wherever he goes, no matter how hard he tries to avoid the situation, it seems that somebody is always ready to challenge Bobby Buttafuoco. "All the time," says the 57-year-old. The challenge has less to with his surname than his forearms. For the record, yes, he is related to that Buttafuoco; Joey -- of Amy Fisher infamy -- is his younger brother. But often the challengers don't even know Bobby's last name. They just know him as the old Arm Wrestler. And in the parlance of that once-underground-now-almost-mainstream sport, they're ready to "pull." In other words, to face off, elbow to elbow, in the classic arm-wrestling stance, and mobilize all their strength until one guy's forearm is "pulled" away from his center of power, and collapsed on the table.
