Active Voice: The Downside of Energy Drinks - Negative Performance and Psychological Effects
By Conrad Woolsey, Ph.D., CHES    Share    Share on FacebookTwitterShare on LinkedinE-mail article
Active Voice is a column by experts in science, medicine and allied health. The viewpoints expressed do not necessarily reflect positions or policies of ACSM.

Conrad Woolsey, PhD, CHES, is an Assistant Professor of Health and Human Performance at Oklahoma State University and a sport psychology consultant. His research areas include brain chemistry, addiction, positive health behavior change, health psychology and performance in athletes. He has authored publications and several research presentations related to this commentary1 including one at ACSM’s Annual Meeting and World Congress on Exercise is Medicine™, held in Baltimore in June 2010. For further information, contact the author by e-mail via his institutional website.

Of the more than 500 brands of energy drinks (EDs) now available, several contain 3-4 times the amount of caffeine (300+ mg/8 oz.) as standard energy drinks (80 mg/8 oz.) such as Red Bull. New popular drinks such as Spike and Redline also contain other herbal stimulants such as evodamine and yohimbine which are more powerful and dangerous than caffeine. Strategic marketing campaigns proclaiming improved performance, concentration, and mood have influenced increased ED use. ED use significantly predicts increased alcohol use, the illicit use of amphetamines (Adderall), and risk-taking such drinking and driving. Additionally, in a randomly assigned double-blind placebo controlled study where we tested EDs on a dynamic performance skill, we found performance improvements only when examining one-dimensional variables (e.g., reaction time), which do not necessarily translate well into coordinated multi-dimensional skills. Performers perceived they were doing better, but actually made significantly more errors, due to being hyper-focused and/or over-aroused. Technical skills rely on timing and coordination, and EDs can and often do reduce performance. As a sport psychology consultant, I regularly work with elite athletes whose performances have suffered from using EDs, particularly in high-pressure situations.

Professors, did you know that Exercise and Sport Sciences Reviews (ESSR) launched an online journal club feature this summer? You can use the journal club questions to help students gain a greater understanding and to facilitate thought-provoking discussion of the topic. Each issue of the journal will feature discussion questions for a selected article that will be available for free on the journal website.

Journal club questions are available whenever this icon appears: . Click the icon to access the questions.

Download the first covered article, "Nonhomeostatic Control of Human Appetite and Physical Activity in Regulation of Energy Balance" by Katarina T. Borer, which published in the July 2010 issue of ESSR. Download the journal club questions by Barry Braun.

Policy Corner: EIM Media and Policy Committee Planning Strategy
Share   Share on FacebookTwitterShare on LinkedinE-mail article
ACSM’s Exercise is Medicine™ (EIM) initiative took a strong step forward in continuing its success, through an inaugural call of the EIM Media and Policy Committee. This committee was one of seven committees created under EIM and is responsible for setting short- and long-term goals for the policy and media efforts of EIM including:
  • Ramping up current media efforts to increase awareness of EIM initiatives as well as strategize on different opportunities and events which will allow for more media exposure
  • Creating and promoting an advocacy agenda for EIM’s mission and goals that actively engages federal government and state governments for specific legislative or regulatory changes
EIM already has been successful in its media and policy efforts and looks forward to continuing that trend with the work of the committee. One recent landmark was Surgeon General Regina Benjamin, M.D., M.B.A. accepting the position as the honorary chair of Exercise is Medicine, and leading community walk from the Baltimore Convention Center to the Inner Harbor. Dr. Benjamin now is leading walks for health in communities around the U.S.

Members of the Media and Policy Committee include:
  • Pamela Peeke, M.D., Chief Medical Correspondent for Discovery Health TV and National Spokesperson for EIM
  • Steven Galson, M.D., former U.S. Surgeon General
  • Jim Ryun, former Congressman and Olympic Runner
  • Melissa Johnson, former Executive Director, President’s Council on Physical Fitness and Sports
  • Janet Rankin, Ph.D., FACSM, Associate Dean and Professor of Nutrition and Exercise, Virginia Tech
  • Sean Keefer, Director of Government Relations and Policy, ACSM
  • Adrian Hutber, Ph.D., Vice President, Exercise is Medicine, ACSM

Take Action for National Childhood Obesity Awareness Month
Share   Share on FacebookTwitterShare on LinkedinE-mail article
Next month, the U.S. will recognize its first-ever National Childhood Obesity Awareness Month, calling national attention and action to the epidemic of childhood obesity. Adults and children are building awareness about childhood obesity and celebrating healthy lifestyles by hosting events in their communities during National Childhood Obesity Awareness Month.

ACSM invites you to visit the National Childhood Obesity Awareness Month website to discover ways you can take action in your community. The website features a toolkit with ideas for fun, health-centric events, such as:
  • Community outing to a local farmers market
  • A “walking school bus” where children can safely walk to school
  • Neighborhood picnic with healthy, kid-friendly meals
  • Health fair at a school or community center
Events like these—which your organization may be planning for September—all support the objectives of National Childhood Obesity Awareness Month. At the website, you can submit them for listing on a growing calendar tracking events throughout the country.

The toolkit also contains resources to help you publicize and promote National Childhood Obesity Awareness Month in your local media and with elected officials.

Anxious Kids? Let Them Walk to School
TIME Magazine    Share    Share on FacebookTwitterShare on LinkedinE-mail article
A stroll to school in the morning can help kids prep for the stresses that await them in the classroom. They'll have less severe increases in heart rate and blood pressure when they're put on the spot, and will feel less anxious about it to boot -- or at least that's the implication from a new study by researchers at the University of Buffalo medical school. Those researchers randomly assigned a group of kids aged 10 to 14 either to sit in a comfy chair while watching a slide show of a suburban neighborhood (to simulate a car ride) or to walk a mile on a treadmill, wearing a backpack, while the same slide show played (to simulate a walk to school -- a little corny perhaps, but not ineffective). All the kids were then told to relax for 20 minutes with some magazines to read. Then they were asked to take a quick test -- the famous Stroop task, where you have to read the name of color when the word has been printed in a different colored font. (E.g. The word "orange" is printed in blue.) The kids who'd walked a mile showed fewer signs of physical stress in front of the testers -- with statistically significantly smaller increases in heart rate and systolic blood pressure -- and gave lower ratings, too, when asked about how stressed they actually felt. Exercise, it seems, "may dampen children's cardiovascular reactivity when confronted with cognitive stressors during the school day," the researchers write in the journal Medicine & Science in Sports & Exercise.

Confused About Fitness Regimens? Poll Tracks Trends
Ottawa Citizen    Share    Share on FacebookTwitterShare on LinkedinE-mail article
Pilates or yoga? Kettlebells or free weights? Running or spinning? If you are dizzy from trying to choose among all the fitness regimens out there a new survey of fitness and health experts, who were asked to identity the top trends, may help. Experienced fitness professionals topped the list while strength training, core work, special fitness programs for older adults, pilates and balance training also made the top ten. "We give the fitness professional some idea of what they're going to see," said Dr. Walter Thompson, of the American College of Sports Medicine (ACSM) which conducted the poll. More
