[Dynamics of systemic and local physiological indices while changing intensity of physical load]
Abstract:
It is well known that metabolic, cardiovascular and respiratory indices during exercise of moderate intensity are linearly related to exercise power. After the load reaches the definite level this relationship changes for nonlinear. Different methods of evaluating the intensity of load at which this transition takes place are discussed. The methods for investigation of transient process dynamics in energy supply of muscle contractions with changing intensity of contractions is described. The dependence of dynamic characteristics of physiological indices from fitness level and in its turn from age and level of physical activity is discussed.

Exercise and Cardiovascular Response
Light to moderate physical activity initiates a series of interconnected responses in the body. The heart rate modestly increases in anticipation of the workout, followed by widespread vasodilation as oxygen consumption by skeletal muscles increases. This results in decreased peripheral resistance, increased capillary blood flow, and accelerated...
Cardiac Output I:Effect of Heart Rate on Cardiac Output
Cardiac output (CO) refers to the total amount of blood ejected by one of the ventricles in liters per minute (L/min). In a resting adult, CO ranges from 5 to 6 L/min, adjusting according to the body's metabolic requirements.
Effect of Heart Rate on Cardiac Output
Cardiac output adapts to metabolic demands during stress, physical activity, or illness. The autonomic nervous system regulates heart rate via the sinoatrial node. The parasympathetic nervous system decreases heart rate...
