Active Voice: Does Vitamin D Have a Role in Preventing Sarcopenia?
By Caitlin Mason, Ph.D.
Viewpoints presented in SMB commentaries reflect opinions of the authors and do not necessarily reflect positions or policies of ACSM.

Dr. Mason is a postdoctoral research fellow at the Fred Hutchinson Cancer Research Center in Seattle, WA. With a background in epidemiology, her research focuses primarily on understanding the mechanisms that link nutrition, exercise, and body composition to chronic disease risk, including cancer.

This commentary presents Dr. Mason’s views associated with a research article she and her colleagues published in the April, 2013 issue of ACSM's
Medicine and Science in Sports and Exercise® (MSSE).

Lifestyle changes leading to modest weight loss of 5-10% are generally sufficient to yield significant improvements in a variety of chronic disease risk factors and are widely recommended. During weight loss, however, a higher ratio of muscle-to-fat mass is lost in older compared to younger adults. Thus, the potential for muscle loss is sometimes a deterrent to prescribed weight loss for overweight and obese older adults, particularly those with or at risk of sarcopenia. More

Steps, Time, Distance: However Measured, Walking Can Reach Health Goals
Los Angeles Times
At a time when many Americans spend their days exercising nothing but their thumbs to exhaustion, others have grown obsessed with steps.

Each footfall, from getting the mail to getting in a run, is tracked on the way to 10,000 — a not-so-magic number that's been turned into a fitness grail. Ten thousand steps is about five miles, depending on the stride, a distance that seems shorter when you start adding in every step from waking to sleeping. Still, many people barely log 3,000 steps per day.

You'd have to live in another galaxy to have missed the admonition to walk for health, to counter our sedentary jobs and hobbies: Walk the dog, park far from the store, take the stairs, schedule a walking meeting. It's exercise that's accessible to most people in most places. It improves cardiovascular health, strengthens bones and boosts mood. It uses calories. And it's simple.More
