The influence of fermented dairy whey on morphofunctional indices and physical training of sportsmen

AbstractThe aim of the study was to examine anthropometry, physical fitness, metabolism at the level of the microcirculation and adaptive processes of the organism as a whole under the inclusion of enzyme-hydrolyzed whey in the diet of 27 weightlifters 17–23 (21.7±2.7) years old, with the level of sports skills of 1 category of up to masters of sports. The body composition was determined by bioimpedance method, functioning of microcirculation system and oxygen transport were determined using the multifunction laser diagnostic complex. For analysis of heart rate variability we used complex “Varicard 2.51”, physical fitness was assessed by generally accepted pedagogical tests. The products inclusion in the diet in the increasing dose of 0.5 to 1.5 g/kg of body weight within 21 days increases physical fitness. The growth of physical efficiency provided change of body composition with slight increase in muscle mass by 2% and decrease in fat component by 3.6% (p<0.05). Increasing muscle mass is the functional stimulus for the revitalization of the microcirculation system for the exchange of nutrients and energy. Under the consumption of serum the intensity of microcirculation increased by 131%, elevating dominance of active mechanisms of modulation of the flow over passive. As a result of intensive diffusion of oxygen from the blood into tissues, the saturation rate of mixed blood reduced by 7.7% and consumption of oxygen by cells of work tissues increased by 23.6%. Assimilation of nutrients and energy, adequate to physical exercises, improved functional capacity of the organism in general and extended its adaptive capacity, as evidenced by the increase of the balance of vegetative regulation of cardiac rhythm.
