Book excerpt: Supine exercise was used as a perturbation to increase central oxygen transport (Q), through an increase in stroke volume (SV), (Bevegard et al., 1966; Miyamoto et al., 1983). It was hypothesized that if the central transport system was an age-related limitation to VO$\sb2$ kinetics in older adults then the supine model should alleviate the problem.

This book was released on 2012 with total page 152 pages. Available in PDF, EPUB and Kindle. Book excerpt: Introduction: The use of heart rate monitors to gauge exercise intensity is widespread throughout the world. The ability to assess intensity through heart rate comes from the linear relationship between heart rate, oxygen consumption and power output. This relationship can be affected by spinal cord injury. Only one previous study (Valent, Dallmeijer et al. 2007) has reported the individual responses seen in tetraplegic participants, and they suggested the loss of linearity is due to the loss of sympathetic activation post injury. Purpose: To investigate the linearity of the heart rate to oxygen consumption relationship in well trained individuals with tetraplegia and relate the relationship response to autonomic function through heart rate variability. Methods: In a case control study 10 well trained tetraplegic and 10 able-bodied control participants performed a discontinuous step arm cranking protocol to determine heart rate to oxygen consumption relationship linearity. Expired air and heart rate were measured over the final minute of each stage. Participants then performed two testing sessions consisting of five minutes rest, eight minutes of exercise at a constant workload followed by ten minutes recovery. This was designed to investigate heart rate variability responses during moderate and heavy intensity exercise. Results: Linear heart rate to oxygen consumption relationships were found in 9 out of 10 tetraplegic and 9 out of 10 able-bodied participants (P

Available in PDF, EPUB and Kindle. Book excerpt: This presentation describes various aspects of the regulation of tissue oxygenation, including the roles of the circulatory system, respiratory system, and blood, the carrier of oxygen within these components of the cardiorespiratory system. The respiratory system takes oxygen from the atmosphere and transports it by diffusion from the air in the alveoli to the blood flowing through the pulmonary capillaries. The cardiovascular system then moves the oxygenated blood from the heart to the microcirculation of the various organs by convection, where oxygen is released from hemoglobin in the red blood cells and moves to the parenchymal cells of each tissue by diffusion. Oxygen that has diffused into cells is then utilized in the mitochondria to produce adenosine triphosphate (ATP), the energy currency of all cells. The mitochondria are able to produce ATP until the oxygen tension or PO2 on the cell surface falls to a critical level of about 4–5 mm Hg. Thus, in order to meet the energetic needs of cells, it is important to maintain a continuous supply of oxygen to the mitochondria at or above the critical PO2 . In order to accomplish this desired outcome, the cardiorespiratory system, including the blood, must be capable of regulation to ensure survival of all tissues under a wide range of circumstances. The purpose of this presentation is to provide basic information about the operation and regulation of the cardiovascular and respiratory systems, as well as the properties of the blood and parenchymal cells, so that a fundamental understanding of the regulation of tissue oxygenation is achieved.

Download or read book Skeletal Muscle Circulation written by Ronald J. Korthuis and published by Morgan & Claypool Publishers. This book was released on 2011 with total page 147 pages. Available in PDF, EPUB and Kindle. Book excerpt: The aim of this treatise is to summarize the current understanding of the mechanisms for blood flow control to skeletal muscle under resting conditions, how perfusion is elevated (exercise hyperemia) to meet the increased demand for oxygen and other substrates during exercise, mechanisms underlying the beneficial effects of regular physical activity on cardiovascular health, the regulation of transcapillary fluid filtration and protein flux across the microvascular exchange vessels, and the role of changes in the skeletal muscle circulation in pathologic states. Skeletal muscle is unique among organs in that its blood flow can change over a remarkably large range. Compared to blood flow at rest, muscle blood flow can increase by more than 20-fold on average during intense exercise, while perfusion of certain individual white muscles or portions of those muscles can increase by as much as 80-fold. This is compared to maximal increases of 4- to 6-fold in the coronary circulation during exercise. These increases in muscle perfusion are required to meet the enormous demands for oxygen and nutrients by the active muscles. Because of its large mass and the fact that skeletal muscles receive 25% of the cardiac output at rest, sympathetically mediated vasoconstriction in vessels supplying this tissue allows central hemodynamic variables (e.g., blood pressure) to be spared during stresses such as hypovolemic shock. Sympathetic vasoconstriction in skeletal muscle in such pathologic conditions also effectively shunts blood flow away from muscles to tissues that are more sensitive to reductions in their blood supply that might otherwise occur. Again, because of its large mass and percentage of cardiac output directed to skeletal muscle, alterations in blood vessel structure and function with chronic disease (e.g., hypertension) contribute significantly to the pathology of such disorders. Alterations in skeletal muscle vascular resistance and/or in the exchange properties of this vascular bed also modify transcapillary fluid filtration and solute movement across the microvascular barrier to influence muscle function and contribute to disease pathology. Finally, it is clear that exercise training induces an adaptive transformation to a protected phenotype in the vasculature supplying skeletal muscle and other tissues to promote overall cardiovascular health.
