Nine men and nine women sustained an isometric contraction at 20% and 80% of maximal voluntary contraction (MVC) force until task failure during separate sessions. The men had a shorter time to failure than women for the 20% but not the 80% MVC …

Physiological Effects Of Vibration In Select Populations, Colleen S. Maloney-Hinds

Loma Linda University Electronic Theses, Dissertations & Projects

Recently, researchers have demonstrated that Whole Body Vibration results in significant increases in skin blood flow. No study has determined if there is an optimal frequency or duration for optimizing this response. In addition, there is no known mechanism for the increase in skin blood flow. It is hypothesized that nitric oxide (NO) is responsible for the increase in skin blood flow due to its ability to vasodilate the smooth muscle in response to shear stress. Therefore, the purpose of this research was to determine the optimal frequency and duration of vibration and determine if NO is the mechanism for …

The Physiological Consequences Of Bed Rest, Kristin J. Stuempfle, Daniel G. Drury

Health Sciences Faculty Publications

Bed rest often is used to treat a wide variety of medical conditions. However, bed rest results in profound deconditioning of the body. Bed rest reduces the hydrostatic pressure gradient within the cardiovascular system, reduces muscle force production, virtually eliminates compression on the bones, and lowers total energy expenditure. This review focuses on the deconditioning that occurs in the cardiovascular, muscular, and skeletal systems following bed rest. Reduction in plasma volume reduces cardiac preload, stroke volume, cardiac output, and ultimately, maximal oxygen consumption. Skeletal muscle volume, muscle cross sectional area, and fiber cross sectional area decrease, which results in diminished …
