Active Voice: Does Incidental Physical Activity Promote Aerobic Fitness?

Viewpoints presented in SMB commentaries reflect opinions of the authors and do not necessarily reflect positions or policies of ACSM.
K. Ashlee McGuire, Ph.D., works on the health promotion, disease and injury prevention team at Alberta Health Services in Calgary, Alberta, Canada. Her work focuses on healthy child and youth development. Robert Ross, Ph.D., FACSM, holds faculty appointments in both the School of Kinesiology and Health Studies and in the Department of Medicine at Queen’s University in Kingston, Ontario, Canada. His research is focused on the characterization and management of obesity and its related comorbidities in adults. This commentary presents McGuire’s and Ross’ views associated with the research article they published in the Nov. 2011 issue of Medicine & Science in Sports & Exercise® (MSSE).
The Physical Activity Guidelines for Americans state that some physical activity is better than none and that adults who participate in any amount of physical activity will experience some health benefits. However, when considering a change in physical activity habits to improve health, many individuals still think that longer bouts of structured exercise (i.e., 30 minutes of moderate-to-vigorous physical activity on a treadmill) are the only way to gain meaningful improvements.
Unfortunately, 30 minutes is an overwhelming amount of daily physical activity for an individual who does not typically accumulate structured physical activity. As a consequence, this individual either attempts to engage in a structured physical activity program for a short period before giving up because it is too difficult or decides to continue living an inactive lifestyle without attempting to change his or her physical activity habits. This is a very disheartening, and unfortunately common, situation. More
Policy Corner: Obama Pleases Science Community with Support for Research
Those who believe science is part of the solution to many challenges facing the U.S. took heart Jan. 24, when President Obama underscored basic research as a budget priority in his fourth State of the Union address.
The following update comes from FASEB (Federation of American Societies for Experimental Biology), of which ACSM is a constituent society.
As many of you probably know, President Barack Obama mentioned the importance of basic research during his State of the Union speech and urged Congress not to gut our investments in research and innovation. A transcript of the President’s speech is available here. The comments about research were in the middle of the speech and appear below: More

Americans Remain a Step Behind the World Actually Thousands of Steps Behind
If you read this standing up, instead of sitting down, you will expend about 20% more energy. If you read it while walking slowly, you’ll expend 300% more energy. These numbers tell an important part of the weight control story. Lots of activity can greatly improve weight loss and the maintenance of weight loss. Remaining sedentary, by contrast, increases the risk of weight gain.
Our obesogenic culture encourages sedentary living. Some recent studies have helped quantify this aspect of our obesogenic culture by describing to what degree Americans take fewer steps than people in other countries and which Americans take more steps (Older? More overweight? Women vs. men? People from the Midwest vs. Northeast?) The rationale for these studies includes the desire to understand the nature of the problem in more detail – and to use that understanding to find better ways of changing it. More
A Simpler Way to Measure Your Workout
Fox News Latino Share
So many people step on the treadmill or the StairMaster without having any clue of what to do with all those numbers flashing on the console.
If you don’t have any intention of wearing a heart rate monitor to gauge the intensity of your workout and you’re not sure about your Rating of Perceived Exertion, it may be worth to take a look at the Metabolic Equivalent (METs) measurement that many exercise equipment have.
The American College of Sports Medicine (ACSM) states that METs are a useful and convenient way to describe the intensity of a variety of physical activities. One MET equates to 3.5 ml.Kg-1.min-1. This is pretty much the oxygen consumption at rest so when you see on the console 6 METs. It suggests you’re working at 6 times the resting metabolic rate. More
