Active Voice: Exercise and Breast Cancer Survival
By Kerry S. Courneya, Ph.D.
Viewpoints presented in SMB commentaries reflect opinions of the authors and do not necessarily reflect positions or policies of ACSM.

Kerry S. Courneya, Ph.D., is a professor and Canada research chair in physical activity and cancer at the University of Alberta in Edmonton, Canada. His research program focuses on physical activity and cancer survivorship including how exercise may help cancer survivors cope with treatments, recover after treatments and extend long-term survival.

This commentary presents Dr. Courneya’s views on the topic of a research article which he and his colleagues published in the September 2014 issue of Medicine & Science in Sports & Exercise® (MSSE).

Exercise has many positive outcomes for cancer patients and survivors including improvements in health-related fitness, symptom management and quality of life. Nevertheless, perhaps the most compelling question for cancer patients and oncologists is whether exercise can improve cancer outcomes. A growing number of observational studies have suggested that physical activity after a breast cancer diagnosis is associated with a lower risk of breast cancer- specific and all-cause mortality. Of course, there are many explanations for why physically active breast cancer survivors may live longer than inactive breast cancer survivors—and these explanations may be unrelated to the causal effects of exercise. Phase III randomized controlled trials would provide a definitive answer to this question, but there are methodological and logistical challenges in conducting such studies.

ACSM Plays Key Role in ENRICH Act, Introduced in Congress Last Week

Last Tuesday, ACSM participated in a congressional briefing to educate members of Congress and its staff on the importance of physical activity and nutrition in the curricula of U.S. medical schools. Specifically, the briefing focused on H.R. 1411, the ENRICH Act, which proposes a $15 million competitive grant to expand physical activity education and nutrition education programs for at least 30 U.S. medical schools. A similar bill was introduced in the last Congress that focused exclusively on nutrition education. However, ACSM played the lead role with partner organizations to successfully have physical activity education included in the bill for the 114th Congress. James Hagberg, Ph.D., FACSM, professor in the department of kinesiology at the University of Maryland, testified on behalf of ACSM regarding the issues of physical inactivity and the importance of including physical activity in medical schools curricula. H.R. 1411 was introduced by Representatives Tim Ryan and Pat Tiberi and has been referred to the House Committee on Energy and Commerce.More

You Might as Well Jump — Everyone Else Does These Days
The Washington Post
Lenny Bernstein, writer of To Your Health blog, writes: "Two years ago, when I was still co-writing The Washington Post's fitness column, I decided, in honor of the NCAA tournament, to see if I could improve my jumping ability — despite being overweight, in my mid-50s and generally earthbound. It didn't work out too well, but I got to meet Brandon Todd, who at 5'5" easily dunked a basketball, and told me he had been doing so since he was 5'2" and 13 years old.

Now everywhere I go, people seem to be jumping as part of their workouts. They jump on and off boxes, they skip rope, they're leaping all kinds of things on Parkour courses. At Crossfit boxes that are now more plentiful than snow in Boston, someone always seems to be jumping on or off something. Check out this guy's 64-inch vertical leap from a standing start.

With the tournament here again and young men preparing to fly across my TV, I got to wondering why everyone seems to be jumping these days. I spoke to Walt Thompson, a professor of exercise physiology at Georgia State University, who has studied plyometrics — a form of exercise that uses jumping, hopping and bounding to develop muscle power — who broke it down for me."

Ancient Practice of Yoga Now a Growth Industry
USA Today
Yoga is an ancient discipline, but it seems to get hotter all the time.

Nearly 10 percent of U.S. adults and 3 percent of children participated in yoga in 2012, up from 5% of adults and 2 percent of children a decade earlier, says a new survey from the National Institutes of Health and the Centers for Disease and Prevention.

Another survey, from the Sports & Fitness Industry Association, says more than 24 million U.S. adults practiced yoga in 2013, up from 17 million in 2008. That makes it roughly as popular as golf.

Other signs that yoga is a growth industry: More
