Active Voice: The Tortoise and the Hare - A Sex Difference in Marathon Pacing
By Robert O. Deaner, Ph.D. and Sandra K. Hunter, Ph.D., FACSM


Robert O. Deaner, Ph.D. Sandra K. Hunter, Ph.D.
Viewpoints presented in SMB commentaries reflect opinions of the authors and do not necessarily reflect positions or policies of ACSM.

Robert O. Deaner, Ph.D., is an associate professor in the Department of Psychology at Grand Valley State University in Allendale, Mich. His overarching goal is to contribute to a scientific understanding of human nature, especially by demonstrating the value of evolutionary theory. Most of his current projects involve sex differences and sports.

Sandra K. Hunter, Ph.D., FACSM, is a professor in the exercise science program with the Department of Physical Therapy at Marquette University in Milwaukee, Wisc. Her research focus includes understanding the mechanisms for (1) sex and age differences in motor control, neuromuscular fatigability and human performance in healthy and clinical populations; and (2) the added effects of stress and exercise training on motor control and fatigability of old adults and clinical populations.

This commentary presents Drs. Deaner’s and Hunter’s views on a topic related to the research report that they and their colleagues recently authored. The report of their original investigation appears in the March 2015 issue of
Medicine & Science in Sport & Exercise® (MSSE).More

ACSM Convenes Scientific Roundtable in D.C. This Week

With funding support from Kaiser Permanente, ACSM is convening a scientific roundtable entitled, "Call to Action on Making Physical Activity Assessment and Prescription a Medical Standard of Care," on Monday and Tuesday of this week (April 27-28) at the Kaiser Permanente Center for Total Health in Washington, D.C. The goals of the roundtable include creating a call to action plan for advancing physical activity as the standard of care within the medical community and developing a manuscript for publication that summarizes the recommendations and tasks for the call to action.

As the roundtable chair, Robert E. Sallis, M.D., FACSM, is facilitating discussion on three modules during the two-day meeting. The modules include:

In addition to Dr. Sallis, esteemed ACSM members and volunteers participating include: Aaron Baggish, M.D., FACC, FACSM; Wojtek Chodzko-Zajko, Ph.D., FACSM; Ted Eytan, M.D., M.S., MPH; Barbara Fletcher, RN, MN, FAHA; Barry Franklin, Ph.D., FACSM; Andrew Gregory, M.D., FACSM; Elizabeth Joy, M.D., MPH, FACSM; Lisel Loy, JD; Gordon Matheson, M.D., Ph.D., FACSM; Jason Matuszak, M.D., FAAFP; Patrick McBride, M.D., MPH, FACC; Francis O’Connor, M.D., MPH, FACSM, COL; James Puffer, M.D., FACSM; Jennifer Trilk, Ph.D. and Janet Williams, M.A.More

Lifestyle Medicine Webinar Series for Weight Management and Prevention

The European Society of Lifestyle Medicine (ESLM) and Elsevier, a leading provider of information solutions, are launching a free webinar series on lifestyle medicine beginning May 5 at 10:00 a.m. EDT / 7:00 a.m. PDT. ACSM President Carol Ewing Garber is a presenter on this webinar, which will give an overview of lifestyle medicine, the new evidence-based branch of health care, to address the underlying causes of the obesity and the modern lifestyle-disease epidemic.

Today, lifestyle-related, non-communicable chronic diseases (NCDs) and obesity represent a leading threat to human health and development. They are the world's biggest killers, causing an estimated 35 million deaths each year — 60% of all deaths globally.

Lifestyle medicine, or changes in lifestyle, is the only tool to reverse obesity and help alter the energy balance of at-risk individuals in a positive direction. Although global health authorities have signed a declaration concerning these matters, little progress has been made and many experts are becoming increasingly concerned.

This webinar series is an introduction to lifestyle medicine strategies for weight management and chronic disease prevention. Register today at http://eu-lifestylemedicine.org/lifestyle-medicine-webinar/.More

Top Tips for Getting Fit (If You're Not Much of an Athlete)
Star Tribune
Your running shoes/tennis racquet/softball glove/high-school sports trophy collection are tucked into the back of some closet, quietly gathering dust. Nowadays your main form of exercise is walking between the couch and the fridge. You're handier with the remote than you are with a racquet.

And yet ... you'd like to be in better shape. Maybe even train in a particular sport. Maybe even compete in the Senior Games. Crazy, right — at your age?

Nope. You're never too old for physical activity, said Mary Frances Visser, a professor of human performance at Mankato State University who researches the effects of exercise on older adults.

"Physiologically there are no real limits," said Visser, an associate editor for the Journal of Aging and Physical Activity. "You're limited by your own physiology in certain ways, but in terms of saying 'Nobody over the age of 60 should ever do X' — that’s nuts."

Aging itself can bring upon a desire for better health, said Gary Westlund, founder and president of Charities Challenge, a nonprofit that sponsors races focusing on health issues.

"It's a very common experience that people, when they get into their 60s and even 70s, one of their motivations is, 'I want to be a better man this year than I was last year,' That includes, of course, 'I want to be healthier, fitter, I want to run faster, row faster," said Westlund, who is certified as a health and fitness specialist by the American College of Sports Medicine.

Lifting at Any Age has Rewards, but after 50 it can Change Your Life
Nj.com
The antidote for issues that attack those aged 50 and older — joint stiffness, sore backs, sleep troubles — may very well be pumping iron. Yes, strength training later in life has many benefits. As men and women age, their muscle fibers shrink in number and in size, contributing to a loss of strength, balance, and coordination. Remarkably, people can experience some of these declines as early as their 40s. Genetics, diet, smoking, alcohol use and, especially, lack of physical activity, may all contribute to this decline. But the good news is that resistance exercise can reverse much of this decline and increase the size of shrunken muscle fibers.

While most older adults are aware they need regular aerobic exercise like walking, swimming or running to strengthen their heart and lungs and tone their bodies, many do not do any form of weight or resistance training. More and more research is finding that it is, in fact, the only type of exercise that can substantially slow, and even reverse, the declines in muscle mass, bone density and strength that were once considered unavoidable parts of aging.

As a measure of its importance in the lives of people over 50, the American College of Sports Medicine now has fitness guidelines specific to weight training for folks in that age group. The advice: resistance training exercises should be performed two to three times a week to work major muscle groups including arms, legs and the core. The goal: lift a weight that's heavy enough to achieve 10 to 15 repetitions per session before muscles become fatigued. ACSM recommends both strength training and aerobic activity on a regular basis; 20 to 60 minutes of aerobic activity is advised three to five days a week, and weight training should be done for 20 to 30 minutes two to three times a week.
