Active Voice: Is Kenyan Running Success an Attribute of Ventilatory Capacity?

Viewpoints presented in SMB commentaries reflect opinions of the authors and do not necessarily reflect positions or policies of ACSM.

Dr. Foster is an Assistant Professor in the School of Health and Exercise Sciences at the University of British Columbia — Okanagan. His primary research activities relate to cardiopulmonary adaptations to physiological stressors.

Dr. Sheel is a Professor in the School of Kinesiology at the University of British Columbia — Vancouver. His principle research areas relate to respiratory and exercise physiology. Dr. Sheel also is a member of ACSM.

This commentary presents Dr. Foster's and Dr. Sheel's views on the topic of a research article which they and their colleagues published in the April 2014 issue of Medicine and Science in Sports and Exercise® (MSSE).


It is commonly believed that the capacity of the normal lung is "over-built" and exceeds the demand for pulmonary O2 transport in the healthy, exercising human. However, in some highly fit endurance athletes, the pulmonary system appears underbuilt relative to the demand for maximal O2 transport. For example, work from our lab and other labs have shown that many highly trained endurance athletes experience pulmonary limitations that can contribute to diminished exercise performance. For example, low amounts of O2 in arterial blood, a high work of breathing and reaching the ventilatory capacity have each been shown to be pulmonary system limitations and thus each can have consequences to maximal O2 uptake and exercise performance.

Policy Corner: Dan Glickman on Physical Fitness as a National Priority

Editor's Note:
This week, we feature an op-ed piece co-authored for Military Times by former U.S. Secretary of Agriculture Dan Glickman. He and his colleagues make a strong argument for healthy lifestyles as a priority for national defense, citing decreasing fitness levels of prospective and active members of the U.S. military.

Opinion: Health Initiatives Can Save Money, Boost Readiness


Dan Glickman
Creating budgets for the Defense Department is always challenging. But determining where to cut and where to spend requires an intense analysis of high-cost line items.

Health costs — Medicare and Medicaid — continue to rise much more rapidly than spending in other sectors. The defense budget is not immune: military health spending has reached $50 billion annually, and is almost 10 percent of the overall defense budget.

This cost of health care for military personnel and their families will continue to rise — just as will costs in the private sector — as rates of dental care, bone injuries, obesity, diabetes, cardiovascular disease, and behavioral issues also rise unless we do something about it. Read the full story at here.

Celebrate Screen-Free Week: May 5 - 11

ACSM is proud to be a supporting partner of Screen-Free Week (May 5 - 11), the annual celebration where children, families, schools, and communities turn on life — by turning off screens.

We all know that children spend far too much time with screens: an astonishing average of 32 hours a week for preschoolers and even more for older children. Too much screen time is linked to poor school performance, childhood obesity, attention problems, and the erosion of creative play. It can also be habit forming.

Celebrate Screen-Free Week and help break the cycle of dependence on TV, tablets, smart phones and computer games. Kids and families will have more time to play, connect with nature, read, daydream, create, explore and spend time with family and friends. And, of course, Screen-Free Week isn’t just about snubbing screens for seven days; it’s a springboard for important lifestyle changes that lead to happier, healthier lives all year!

Screen-Free Week is also a good opportunity to consider how to incorporate tech devices and apps that promote physical activity into your daily life.

For everything you'll need for a great week — including event listings and free resources visit www.screenfree.org.

The 2014 Journal of Clinical Exercise Physiology (JCEP) is Now Available

The Clinical Exercise Physiology Association (CEPA) is pleased to announce the release of its 3rd edition of the Journal of Clinical Exercise Physiology (JCEP). CEPA is an affiliate society of the American College of Sports Medicine and is the only organization with a primary goal to advance the scientific and practical application of clinical exercise physiology for the betterment of the health, fitness and quality of life for patients at high risk of or living with a chronic disease. You can learn more about the work CEPA does to advance the profession of clinical exercise physiology by checking out our website at www.cepa-acsm.org. CEPA also has a booth every year at the ACSM Annual Meeting — please stop in Orlando by to meet CEPA members and learn more about our organization.

JCEP is just one of CEPA's several member benefits and this edition is stocked with great content. Among the reviews in this issue, Dr. Lynette Craft and Dr. Anne Fish shed light on evidence-based practice and the development of scientific statements. Dr. Brad Roy and colleagues discuss the potential of health and wellness coaching to improve patient adherence to behavioral change. In addition, Dr. Dennis Kerrigan and colleagues present an interesting case study on postural orthostatic tachycardia syndrome. In the point/counterpoint, Drs. Paul Visich, Gregory Dwyer and Donald Cummings discuss the merits of different undergraduate routes of study in exercise science with a goal of a career in clinical exercise physiology. Interested in reading the journal? We would love to welcome you to our organization! Membership rates are very reasonable, especially for students at only $15/year.

Like what you're reading in JCEP? Look out for discussions on our Clinical Exercise Physiology Association LinkedIn group over the next few months spotlighting articles in JCEP. This is a great opportunity to share your thoughts with others in the field. We hope to welcome you to CEPA soon.

Exercise, Weight Control Reduce Risk of Breast Cancer
Statesman Journal
Breast cancer can be a devastating disease, but most women can take active steps to reduce their risk, say some of the nation's leading breast-cancer experts.

Women shouldn't blame themselves for their illness, doctors say, noting that it's usually impossible to pinpoint what caused an individual woman's breast tumor.

But about 25 percent of all breast cancer cases in women of all ages could be avoided by maintaining a healthy body weight and doing regular physical activity, said internist Anne McTiernan, a researcher with the Fred Hutchinson Cancer Research Center in Seattle.

"The greatest benefits for breast cancer reduction come from weight control and physical activity together," she said.

Alpa Patel, an American Cancer Society epidemiologist, agrees these are "modifiable risk factors," along with limiting alcohol consumption.

It may seem obvious, but being a woman is the main risk factor for developing breast cancer, the cancer society said.

Consumer Reports
If exercise were a pill, it would be one of the most powerful drugs ever invented, according to Consumer Reports.

Chances are, you have heard many variations of that sentiment. It's not hype. A 2010 review of 40 studies in the International Journal of Clinical Practice, for example, found that being active can help prevent about 25 conditions.

Other research suggests that exercise can cut the risk of colon cancer (60 percent), type 2 diabetes (58 percent), heart disease (40 percent), and Alzheimer's disease (40 percent). Another study, which compared regular exercisers with couch potatoes, concluded that each minute of physical activity added an average of 7 minutes of life span.

Yet powerful evidence isn't powerful enough: Just 20 percent of Americans say they get the recommended amount of aerobic and strength exercises.

"Convenience and proximity are key predictors of exercise," says Carol Ewing Garber, associate professor of movement sciences at Columbia University and president elect of the American College of Sports Medicine. So it makes sense that working out at home increases the odds you will not only become active, but also stick with a routine.

Consumer Reports consulted with experts to help you pick the machine that will best help you reach your health goals.
