Active Voice: Strengthening Muscle for Your Health

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

Martin Sénéchal, Ph.D., CEP, is associate postdoctoral fellow at The Manitoba Institute of Child Health, University of Manitoba, faculty of medicine, department of pediatrics and child health in Winnipeg, Manitoba, Canada. His research focuses on cardiometabolic risk factors, chronic disease and exercise. More specifically, he is interested in the metabolic response to resistance training and the predictors associated with exercise-responders.

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

Exercise is a cornerstone in the management and the prevention of obesity-related chronic conditions. National and international agencies are recommending a minimum of 150 minutes per week of endurance exercise at moderate intensity in conjunction with at least two days of strengthening activity. However, the public generally only remembers the endurance part of this recommendation.

Based on some changes that occur through the lifespan, there is a rationale for emphasizing strength training in individuals. For example, between 20 to 70 years of age, a natural loss in about 40 percent of muscle mass, called “sarcopenia” occurs. In adults, strength training is a rational strategy to attenuate the effect of muscle mass loss. However, it is unknown if older adults can actually increase muscle mass with resistance exercise training. Nevertheless, besides “sarcopenia,” aging is also associated with a decline in muscle strength commonly called “dynapenia.” Interestingly, the rate of loss of muscle strength with aging is much steeper compared to that for muscle mass decline. In other words, individuals lose more muscle strength than muscle mass for a given time period. Therefore, strength exercises should be emphasized to prevent decreases in muscle strength rather than targeting the muscle mass.

Moving Forward: White House Summit and Research Forum on Improved Health and Fitness for Americans with Disabilities
Last week's White House summit and research forum on improved health and fitness for Americans with disabilities was a powerful call to action for both health and research. The Monday session at the White House, as reported in last week’s SMB, highlighted the I Can Do It, You Can Do It (ICDI) Program, release of new guidelines for inclusion and the announcement of a new campaign called Commit to Inclusion.

Tuesday's research forum was held at the U.S. Department of Health and Human Services. The forum featured ACSM members including James Rimmer, Ph.D., and Dan Cooper, M.D. Panels focused on exercise physiology and children with disabilities, nutritional science perspectives, psychology, motivation, environmental considerations and outcomes measurements.

A report and next steps will be developed and made available. We'll note and provide a link to the report in a future SMB once complete. Needless to say, there was fertile and innovative discussion about such topics as inclusion science and implementation science, viewing physical activity as an ecosystem and to prioritize and strategize accordingly and the need for more multi-disciplinary endeavors in advancing science, practice and policy.

Exercise is Medicine® Offers Credential Workshop in Orlando
Exercise is Medicine® (EIM) is presenting a Professional Credential Workshop for fitness professionals who are interested in becoming certified in delivering physical activity intervention programs to at-risk populations. This two-day workshop will be held November 7 and 8, 2014 in Orlando, Florida.

As health care changes rapidly, health systems are focused on identifying patients, employees and community population groups that are at risk for chronic diseases (e.g., obesity, diabetes, hypertension and hyperlipidemia). These at-risk groups are in need of intervention programs to slow, stop and reverse their progression of chronic diseases. The curriculum for this credential workshop is designed to train participants to become part of the community care team that receives referrals from health systems. Faculty at this workshop includes: Felipe Lobelo, M.D., Ph.D.; Paul Estabrooks, Ph.D.; and Adrian Hutber, Ph.D.

The workshop's key concepts include:
  • EIM Solution™ for health care and community
  • Impact of physical activity on chronic diseases
  • Modalities for successful referrals engagement
  • Supporting of sustained lifestyle behavioral change
  • Evaluation of intervention program outcomes

World Pediatric Bone and Joint (PB&J) Day — October 19
The adolescent Female Athlete Triad is the theme of this year’s World Pediatric Bone and Joint (PB&J) Day, which is celebrated October 19. Developed by the multi-disciplinary Pediatric Specialty Group of the United States Bone and Joint Initiative (USBJI), World Pediatric Bone and Joint (PB&J) Day is part of Bone and Joint Health National Action Week. Held October 12-20, the events and projects organized by individuals and organizations worldwide are designed to raise awareness of prevention, disease management and treatments as well as promote advances in a number of areas.

An awareness campaign of education stories about important bone and joint-related conditions about which kids, adolescents and their parents should be aware have been developed. Topics that have been covered include, obesity, slipped capital femoral epiphysis, kids and Vitamin D deficiency.

Sitting Around in Middle Age Doesn't Bode Well for Old Age
HealthDay News via Doctor's Lounge
Your lifestyle at midlife helps predict how active you'll be in old age, a new study says.

Researchers asked 565 adults in Iceland, at an average age of 49, about their lifestyle and other factors. Thirty years later, then 80 on average, their physical activity levels were assessed.

Having a lower level of education, poorer housing, and not being married in midlife were associated with an average of 12, 13 and 15 more minutes of inactivity a day in old age.

Being obese and having heart disease in midlife were associated with an average of 22 and 39 more minutes of inactivity a day in old age.

"Studies suggest that even when you exercise regularly, prolonged periods of sedentary time are a risk factor for cardiovascular disease, type 2 diabetes and even mortality. What is not well understood yet is what factors influence the amount of sedentary time," said the authors of the study.

The results — recently published in Medicine & Science in Sports & Exercise — indicate that risk factors for a sedentary lifestyle in old age can be identified years before, the researchers noted.

Exercise is ADHD Medication
The Atlantic
Mental exercises to build (or rebuild) attention span have shown promise recently as adjuncts or alternatives to amphetamines in addressing symptoms common to Attention Deficit Hyperactivity Disorder (ADHD). Building cognitive control, to be better able to focus on just one thing, or single-task, might involve regular practice with a specialized video game that reinforces "top-down" cognitive modulation, as was the case in a popular paper in Nature last year. Cool but still notional. More insipid but also more clearly critical to addressing what's being called the ADHD epidemic is plain old physical activity.

This morning the medical journal Pediatrics published research that found kids who took part in a regular physical activity program showed important enhancement of cognitive performance and brain function. The findings, according to University of Illinois professor Charles Hillman and colleagues, "demonstrate a causal effect of a physical program on executive control, and provide support for physical activity for improving childhood cognition and brain health." If it seems odd that this is something that still needs support, that's because it is odd, yes. Physical activity is clearly a high, high-yield investment for all kids, but especially those attentive or hyperactive. This brand of research is still published and written about as though it were a novel finding, in part because exercise programs for kids remain underfunded and underprioritized in many school curricula, even though exercise is clearly integral to maximizing the utility of time spent in class.
