Karyn A. Esser, Ph.D., FACSM, is the director of the Center for Muscle Biology and Professor of Physiology at the University of Kentucky. Her lab has studied mechanisms of skeletal muscle adaptation for many years and, recently, she has pioneered research into the role of the molecular clock/circadian rhythms in skeletal muscle.

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. Esser is the chair and Dr. Powers is the co-chair of the Program Committee for ACSM’s Integrative Physiology of Exercise Conference.

It is not too late to register and attend the 2014 ACSM Specialty Conference, “Integrative Physiology of Exercise (IPE)” to be held at the Eden Roc Resort in Miami Beach, Florida on September 17-20.

This extraordinary meeting will begin with a welcome reception and a keynote lecture at 7:00 p.m. on Wednesday, September 17. A brief overview of this meeting follows.


Policy Corner: Physical Activity Guidelines Act Goes to Senate Committee Tomorrow

Tomorrow, the Promoting Physical Activity Guidelines for Americans Act goes to the Senate HELP (Health, Education, Labor and Pensions) committee for review. The act makes provisions for the review and update of the 2008 Physical Activity Guidelines for Americans, published by the U.S. Department of Health and Human Services (HHS), at least every 10 years. The bill is supported by the American College of Sports Medicine and a number of other national organizations and sport governing bodies. The act will:

Once the act has been passed by the committee, it will next move to the Senate floor for vote. The act (S. 531/H.R. 2179) was introduced in the Senate by Senator Tom Harkin and Senator Roger Wicker, and a companion bill was introduced in the House by Representative Ron Kind and Representative Aaron Schock.More

Speedy Pitches, Not Recoveries, in a League of Rising Scars
The New York Times
You don't even feel it, this lightning bolt from the pitching gods, this great separator between ordinary and special, between a healthy arm and a vulnerable one. At least that is how it was for Jarrod Parker, as a teenager in Indiana, the first time he threw a baseball 98 miles an hour. He did not know then what he had done, or what it really meant.

It was the first start of his senior year in high school, Parker remembered, cold and rainy, and his coach held him to three innings. Scouts were there to watch. Parker came out of the game and looked at his father, to get a signal for how hard he had thrown on the scouts' radar gun. His father held up eight fingers.

"And I'm like: 'Eighty-eight? Well, it's cold, whatever, it's early,'" Parker said recently in the home clubhouse of the Oakland Athletics. "And he was like, 'No — 98.' It never feels that much different between throwing a pitch at 88 or 98. You can't see it." The scouts saw it, though, and the fastball helped Parker become the ninth overall draft pick in 2007, by the Arizona Diamondbacks. He zipped along for two years in the minors, then needed Tommy John surgery to repair a torn ulnar collateral ligament. This past March, with the A's, he had the operation again. More

Dealing with Joint Pain? Try Swimming
You've pounded your legs on the pavement for years and just can't seem to put in the miles you used to. Try hanging up the running shoes; don a swimsuit and goggles for the workout that gives you the highest cardio-respiratory fitness compared to any other sport: swimming.

Kris Simpson, an ACSM certified personal trainer, a basketball coach and triathlete admits the swimming portion of the "swim, bike, run" was very challenging.

"Lats and back were sore, your shoulders are tired, my core got stronger, my triceps – [I have] nice swimming arms now," says Simpson.

The challenge of swimming is in the resistance. Water offers between 12 to 14 percent more resistance than air, which forces you to build and tone muscles faster. In a study of men who completed an eight-week swimming program, they saw a 23.8 percent increase in the triceps muscle in the back of the arm.

"The fact that you're using your arms and your legs and you're trying to move through the water makes it a bit of work, makes it a great workout," says Simpson.More
