Previous research has demonstrated that, in general, quality of sleep improves after regular physical exercise. However, a number of factors such as the particular exercise training routines and various individual subjective characteristics complicate this overall conclusion. Army researchers set out to quantify the quality and length of sleep obtained after non-habitual acute resistance and aerobic exercise. Of interest was whether a single workout would be beneficial or harmful in obtaining restful sleep the night following the exercise.
A New Study
The authors of "Non-Habitual Acute Resistance and Aerobic Exercise Affects Sleep" are William J. Tharion, Philip J. Niro, Marilyn A. Sharp, Mark D. Kellogg, Kevin R. Rarick, and Bradley C. Nindl, all at the U.S. Army Research Institute of Environmental Medicine, Natick, MA. They will present their findings at the American Physiological Society's (APS) (www.the-aps.org) annual scientific conference, Experimental Biology 2003, being held April 17-21, 2004, at the Washington, D.C. Convention Center.
Seven men volunteered to participate in the study. Volunteers were physically active (i.e., they participated in recreational sports or their jobs required some physical labor), but they were not engaged in a regular training program. The volunteer's characteristics (all va
