Active Voice: Early Repolarization — Significance in Athletes
By: Philip Aagaard, M.D., Ph.D.
Viewpoints presented in SMB commentaries reflect opinions of the authors and do not necessarily reflect positions or policies of ACSM.
Philip Aagaard is a physician and researcher at Montefiore Medical Center - The University Hospital of Albert Einstein College of Medicine in the Bronx, New York. His research interests include prevention of sudden cardiac death in athletes and the athlete’s ECG.
This commentary presents Dr. Aagaard’s views related to a research report that he and his colleagues authored, which appears in the July 2014 issue of Medicine & Science in Sports & Exercise® (MSSE).
For decades, early repolarization (ER) was considered a benign ECG finding. However, this view was recently challenged by studies associating early repolarization with an increased risk of arrhythmic death in the general population.
Physical training can induce early repolarization, possibly by increasing vagal tone. It is therefore not surprising that early repolarization is prevalent in athletes. In fact, it is even considered a feature of an athlete’s heart. However, in one related study, it was reported that early repolarization was more common in athletes suffering sudden cardiac arrest compared with control athletes. This has sparked debate regarding the significance of early repolarization in the athletic population.More

Policy Corner: Become a Key Contact for ACSM
What does it take to be an ACSM Key Contact? What kind of information is a member of Congress looking for in a presentation? Is it important to communicate with the staff of a member of Congress? How important is it to contact our legislators? What is an ACSM Action Alert?
ACSM member-advocates represent a gamut of expertise, from scientists to physicians to educators and health and fitness professionals. Each brings unique insights and perspectives to help policy makers and staffs inform their decisions. While many ACSM members are involved citizens who participate in town hall meetings, campaign for candidates or issues, or engage in dialogue and debate, few have the deep experience of political professionals. Fortunately, citizen advocacy requires little more than the desire to influence policy and the time it takes to meet with officials or to contact them by phone or email.

Courneya, Ph.D.
The article covers the author's take on the physical activity (PA) and cancer survivorship field and the four general propositions for the field, which the author defines as "the field that studies the links between cancer variables and PA in people who have been diagnosed as having cancer." PA could be a valuable tool for improving the quality of life for the nearly 14 million American cancer survivors.

New Resources Coming: US Report Card on Physical Activity for Children, Youth
At a Congressional Briefing in April, the National Physical Activity Plan (NPAP), in collaboration with ACSM, released the groundbreaking 2014 United States Report Card on Physical Activity for Children and Youth. The National Physical Activity Plan focuses on tactics and strategies for addressing physical activity. The report card is the first in a historic series of report cards that will provide an unprecedented benchmark using a common methodology on this critical public health issue.
The report card's findings served as a wake-up call and prompted coverage by the news media, including this Washington Post article. As the report card outcomes reverberate around the country, two new educational resources are being developed and will be available over the next two months. In early August, a video will be distributed that summarizes the report card's outcomes and subsequent call to action. The video features Peter T. Katzmarzyk, Ph.D., FACSM, chair of the U.S. Report Card Research Advisory Committee and associate executive director at the Pennington Biomedical Research Center at Louisiana State University, and Russell R. Pate, Ph.D., FACSM, chairman of the NPAP Alliance and professor at the Arnold School of Public Health at the University of South Carolina.
A free webinar will be held September 10 to discuss the implications of the PA Report Card, including a question and answer session with Drs. Katzmarzyk and Pate. Check next week's issue of SMB for more information.More
7 Exercises Your Body Wishes You Would Do
RealBuzz via Yahoo
When it comes to working out, the key to being successful is a healthy balance of flexibility, muscular strength, and a strong core. Here are the seven exercises your body wishes you would start doing to give you the perfect workout balance and make you stronger than ever.
Modified press-ups for stronger shoulders
Did you know there is a muscle on the side of your chest called the serratus anterior that is the key to stronger shoulders? This small but mighty muscle helps your shoulder blades move, and you can develop it by making a small modification to the classic press-up movement known as the ‘pushup plus’. Perform a regular press up until the final motion when you push your body back up, and then raise your upper back slightly upwards as you move. Hold for a couple of seconds, and then bring back down. If you’re doing it right, you should be able to feel and see extra movement in your shoulder blades.
Wall slides for stronger knees
Your knees are the weight bearing joint for so many exercises that strengthening them is almost a no brainer. You can do this with a simple exercise known as wall slides, and all you'll need is a medicine ball and, surprise surprise, a wall. With your back against the wall, stand with your legs at roughly shoulder width, and place a medicine ball between your knees. Without taking your back off the wall, slowly slide down the wall, bending your knees until you are almost in a sitting position without letting the medicine ball fall from between your legs. Not only does this great exercise strengthen your knees, it also works your core muscles and quadriceps as well. More
