Active Voice: Q&A -- Dr. Scott Powers on 2010 Integrative Physiology of Exercise (IPE) Conference
By Scott K. Powers, Ed.D., Ph.D., FACSM
Scott K. Powers, Ed.D., Ph.D., FACSM, is a UAA Endowed Professor and Distinguished Professor in the Department of Applied Physiology and Kinesiology at the University of Florida. He investigates effects of muscular exercise and inactivity on both cardiac and skeletal muscle. His research is focused on exercise-mediated changes in cardiac and skeletal muscle antioxidant systems and the role of these changes in protecting against ischemia-reperfusion injury. Dr. Powers has provided significant leadership in ACSM for many years, including a term as vice president in 1997-99. Dr. Powers is the program committee chair for ACSM’s Integrative Physiology of Exercise Conference.

It’s not too late to register for the 2010 ACSM Specialty Conference on Integrative Physiology of Exercise (IPE) to be held at the Eden Roc Resort in Miami Beach, Florida from Sept. 22-25.

In the last several years, Scott Powers, Ed.D., Ph.D., FACSM; George Brooks, Ph.D., FACSM; Ronald Terjung, Ph.D., FACSM and other ACSM leaders have developed a forum where scientists in molecular, cellular, and integrative exercise physiology can come together to exchange on the latest research in the field. What began as a proposal from the ACSM Research Advisory Committee in 2000 became the highly successful ACSM Integrative Physiology of Exercise (IPE) Conference in 2006. The inaugural meeting in 2006 topped 450 attendees, and the 2010 IPE Conference, to be held later this month, hopes to be even larger.

Dr. Powers is the chair of the 2010 IPE Conference. William Herbert, Ph.D., FACSM, ACSM Web Content Editor, had a chance to interview him for Sports Medicine Bulletin so he might share some of the origins, content and features of this unique ACSM conference.

Policy Corner: ACSM to Present Congressional Briefing on Concussion, Youth Sports Issues

As America’s youth return to school and begin athletic practice, tournament play, intramurals and youth league sports, we must focus on policies and practices that will help children safely enjoy sports and other activities. Following the May launch of the Preparticipation Physical Examination (PPE) Campaign and Coalition for Youth Sports Health and Safety, ACSM will host a Congressional Briefing on Youth Sports and Concussion in Washington, D.C. Sept. 23.

A panel of noted experts will address the spectrum of issues relating to the health and safety of youth athletes, with particular emphasis on policies to prevent and appropriately manage concussion. ACSM is working with the Congressional Youth Sports Caucus on a variety of issues. Future briefings will focus on other topics such as overscheduling and overuse injuries, fluid/heat/hydration, and the culture of youth sports.More

An Inside Look: September 2010 Medicine & Science in Sport & Exercise

Check out the September issue of Medicine & Science in Sport & Exercise (MSSE) online now. ACSM members can access the journal for free – simply log in at the ACSM website and click “My ACSM.”

MSSE Editor-in-Chief Andrew J. Young, Ph.D., FACSM offers his insights into the September issue:

This month MSSE features two articles illustrating some yin yang of exercise adaptation. Power et al. report a cross-sectional comparison of masters-level runners, healthy aged-matched and recreationally active younger controls in "Motor Unit Number Estimates in Masters Runners: Use It or Lose It?" which suggests that lifelong high-intensity exercise training may prevent an age-associated decline in motor unit function. However, "Harmful Effect of Land-based Endurance Exercise in Rats with Diabetic Nerve," by Kim and Lee, describes experiments showing that aerobic exercise training can adversely affect nerves in diabetic rats, an effect seemingly more pronounced with treadmill than swimming exercise. This interesting basic science investigation may have clinical implications, if the findings can be translated to humans.

Elsewhere in the September issue, McAnulty et al. report in "Effect of n-3 Fatty Acids and Antioxidants on Oxidative Stress after Exercise," that fit, young men fed omega-3 fatty acid supplements while performing three days of heavy exercise appeared to exhibit more pronounced oxidative stress than subjects fed placebos during the heavy exercise. This observation could suggest that omega-3 fatty acid supplementation is not without some downside potential, but must be confirmed in other subject groups.More

Few Medicines as Strong as Exercise
The Orange County Register
We all know we're supposed to exercise, to move our muscles and be strong. The U.S. Centers for Disease Control and Prevention estimate that about three-fourths of older adults are sedentary, despite informative articles insisting activity helps prevent many related ailments, from coronary artery disease to cognitive decline.More

Heat Stress Injuries in Athletes: Common but Preventable
The Oregonian
After more than a dozen high school football players were hospitalized last week in McMinnville, news reports blamed a "mystery" illness. Emerging details suggest a not-so-mysterious cause: heat stress injury as a result of vigorous training in hot weather at the start of the season when athletes aren't fully conditioned. Such factors set the stage for an estimated 9,200 heat-stress injuries a year in the U.S., according to Ohio State University researchers. Football players accounted for more than 70 percent of cases from 2005 to 2009. More
