title: [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.
