Active Voice: Train High or Low with Carbohydrate? Best Strategies for Improving Sports Performance
By Louise Burke, Ph.D., FACSM, FSMA    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.

Louise Burke, Ph.D., FACSM, FSMA, is Head of Sports Nutrition at the Australian Institute of Sport in Canberra, Australia. Dr. Burke manages a department providing clinical counseling and education of athletes, research, student supervision and teaching, and development of education resources, and she also oversees food services for athletes. Dr. Burke is a member of the Nutritional Working Group for the International Olympic Committee and the Medical and Anti-Doping Commission for the International Association of Athletics Federations. Her research focus relates primarily to the effects of specific nutrient interventions on metabolism and exercise performance in athletes.

Traditionally, athletes have approached their daily workouts to train as hard as possible, using strategies that promote good performance, just as they would in a race or match. In many sports, these strategies involve fueling up with carbohydrates before, during and between workouts to sustain the capacity to produce power. Recently, however, scientists have proposed an alternative approach – training smarter by trying for greater outcomes from the same training impulse. The muscles’ reactions have shown that when a muscle is low in carbohydrate fuel, there is an increased chemical response to a training stimulus. One study by Bengt Saltin’s group in Denmark compared what happened when untrained people completed ten weeks of training with one leg training low (TL) and the other leg training high (TH). Although each leg completed the same training sessions, the TL leg beat out the TH leg in terms of the muscle’s changes and its capacity to exercise until fatigued. While some publicity surrounding this study suggests otherwise, the outcomes from TL weren’t achieved by following a low carbohydrate diet. Rather, this was accomplished by doing two sessions of exercise back-to-back so the muscle had no time to refuel before the second session. Only half of the training was done with low muscle fuel stores.

A NOTE OF THANKS FROM ACSM: ACSM appreciates so much all the candidates in the 2011 elections. ACSM is blessed with an abundance of leadership and we know that always produces difficult and close choices. But ultimately ACSM is the overall winner through such service that all candidates provide. We congratulate the incoming Officers and Trustees, who will formally take their positions at the close of the Denver Annual Meeting. We also deeply thank everyone else for your service and leadership— past, present, and future.

A message from Janet Walberg Rankin, Ph.D., FACSM, 2011-12 ACSM President-elect:

"I could not have guessed 30 years ago, at my first ACSM meeting, that I would be elected as the 56th President of ACSM. I am grateful for this inspiring challenge to serve the membership. I intend to work to advance ACSM’s goals and mission when I begin as President-elect at the 2011 Annual Meeting and World Congress on Exercise is Medicine, May 31 to June 4 in Denver, CO, USA.”

Join ACSM in Celebrating Screen-Free Week
Share   Share on FacebookTwitterShare on LinkedinE-mail article
ACSM is proud to be an official endorser of Screen-Free Week (April 18-24), the annual celebration where children, families, schools and communities turn off screens and turn on life.

We all know that children spend far too much time with screens – preschoolers average an astonishing 32 hours a week, and older children average even more. Excessive screen time is harmful for children. It’s linked to poor school performance, childhood obesity, attention problems and the erosion of creative play.

Screen-Free Week (formerly TV-Turnoff) is a wonderful way to help children lead healthier, happier lives by reducing dependence on entertainment screen media – including television, video games, computers and hand-held devices. By encouraging children and families to unplug, Screen-Free Week provides time for them to play, connect with nature, read, daydream, create, explore and spend more time with family and friends.

Losing Your Grip? It Could be a Clue to Your Health
Los Angeles Times    Share    Share on FacebookTwitterShare on LinkedinE-mail article
Getting a good grip on your health may mean … getting a good grip. The force you can muster when squeezing an object or a weight doesn't only reveal how strong your hand and arm are. It can be a measure of overall muscle function and — according to one recent study — even portend how long you're likely to live. More

The first breakthrough came on the scale, and the second came on a treadmill spinning so fast I half expected to be shot across the gym.

After a week of working out and a 2,000-calorie-per-day diet, I thought I'd make major progress toward my goal of losing 10 pounds in eight weeks. But when I stepped on the scale at Fircrest's Innovative Fitness, it responded with four discouraging numbers: 176.2. I'd dropped exactly 6.4 ounces.
