The results of study of an artificial aortic valve by the heart cycle phase analysis are given in the paper. The main aim of the study is identifying the artificial aortic valve influence on cardiovascular system functions, the way and ranges of these functions change. The results of phase blood volume measurement and the numerical values that characterize the metabolic processes in heart muscles are given herein.
Design of an effective succinate-based agent for the use in sports has required a profound analysis of the main action mechanisms of the agent in question. Our paper reflects basic principles, which are decisive for the design of the offered succinate-based agent to increase the organism performance and the rate of recovery after intensive physical loading. We have treated a special role of the metabolic conversions of succinate in energy exchange of mithochondria: high energy efficiency, possibility of beneficial oxidation under oxygen deprivation, anaerobic formation and possible consequences of the above phenomenon.
