  Actiheart - Ambulatory Energy Expenditure Monitor

The Actiheart is the gold standard for ambulatory measurement of energy expenditure, having been validated against DLW. Combining activity and heart rate measurement in one discreet unit, it is possible to measure AEE in daily living for up to 21 days. The Actiheart can also record HRV data.
 


Active Voice: Athletes, Exercise Training and Cardiac Adaptation
By Angela L. Spence, B.Sc., and Daniel J. Green, Ph.D.
Viewpoints presented in SMB commentaries reflect opinions of the authors and do not necessarily reflect positions or policies of ACSM.

Angela Spence, B.Sc. (Hons) recently submitted her Ph.D. thesis describing cardiac and vascular adaptive responses to different exercise training modalities in healthy humans. She is passionate about the role exercise training plays in disease prevention, disease management and overall improvements in health and quality of life, across all ages. Angela continues her research into exercise training and cardiovascular physiology during a post-doctoral appointment within the School of Sport Science, Exercise & Health, University of Western Australia, Perth.

Winthrop Professor Danny Green is a human integrative and cardiovascular physiologist specializing in cardiovascular disease prevention. His research encompasses the lifespan, from exercise training in the prevention of atherosclerosis development in obese adolescents to research on the best combination of exercise and medications for management of high-risk patients. Dr. Green is based in the School of Sport Science, Exercise & Health at the University of Western Australia, Perth, and also holds an appointment at Liverpool John Moores University, UK.

This commentary presents Ms. Spence’s and Dr. Green’s views on the topic of a research article which they and their colleagues published in the March 2013 issue of
Medicine and Science in Sports and Exercise® (MSSE).

Textbooks of exercise physiology typically indicate that the heart adapts to exercise training in a modality specific manner. This concept owes much to the work of Morganroth and colleagues who, in the 1970s, suggested that cardiac hypertrophy is dependent upon hemodynamic stimuli, in accordance with the Law of Laplace. In essence, endurance exercise is associated with repetitive ventricular volume overload (preload) which elicits an eccentric hypertrophy, whereby mass of the ventricles increases in proportion to their volume. In contrast, resistance exercise exposes the ventricles to episodic increases in pressure (afterload) and is associated with concentric hypertrophy, manifesting as increased ventricular mass without concomitant increases in volume. This paradigm has been reinforced by observations related to pathological changes associated with hypertension and heart failure.

    Policy Corner: Educating Congress – An Ongoing Effort

    The American College of Sports Medicine recently participated in a congressional briefing, continuing a series of activities designed to keep policy makers informed on topics of critical importance. The May 9 briefing in the Cannon House Office Building, sponsored by the National Coalition for Promoting Physical Activity, focused on “How Federal Policy Can Improve Physical Activity and Bolster America’s Youth and Workforce.” James Hagberg, Ph.D., FACSM, of the University of Maryland, led a panel of distinguished experts. Dr. Hagberg’s participation in the briefing came on the heels of his March 13 participation in ACSM’s first Capitol Hill Day (See March 19 SMB.)

    Dr. Hagberg discussed the physical inactivity epidemic and the negative outcomes associated with physical inactivity. He pointed out that "being physically inactive is not exactly an optimal strategy for long-term health." Dr. Hagberg also discussed some of the costs associated with obesity. He noted that an obese person incurs $2000 - $6000 more in annual medical expenses compared to a normal-weight individual and that the estimated annual cost of obesity in the U.S. was $190 billion in 2012.

    The briefing was a step toward educating Members of Congress and their staffs about the need for policies to combat the physical inactivity epidemic. For further questions about the ACSM policy program, please contact Monte Ward, vice president, government relations, at mward@acsm.org.
