Abstract
Purpose: to scientifically substantiate effective mechanisms of organism’s bio-chemical adaptation of ski-racers in competition period with the help of lipid peroxidation indicators, oxidative modification of proteins and activity of hypothalamus pituitary adrenocortical system. Material: in the research 14 sportsmen of 18-25 years’ age (combined team of university) with different level of sportsmanship participated. Assessment of free radical oxidation, anti-oxidant system, cortisol level was fulfilled with the help of indicators’ quantitative analysis by bio-chemical methods applied to blood serum samples. Results: it was found that in the basis of bio-chemical changes under intensive physical loads is increase of catabolic processes’ speed. Change of organism’s metabolic orientation of ski racers at optimal level results in working muscles’ energy supply improvement, increase of energy systems’ power and sports efficiency. Conclusions: Application of interval trainings at stages of preparation to special significant competitions results in expected adaptation and increase of sports efficiency. We also showed their effective role in ensuring long term reactions, conditioning high sports efficiency.
Highlights
Purpose: to scientifically substantiate effective mechanisms of organism’s bio-chemical adaptation of skiracers in competition period with the help of lipid peroxidation indicators, oxidative modification of proteins and activity of hypothalamus pituitary adrenocortical system
In assessment of ski racers’ metabolic state in conditions of concentrated development of local-regional muscular endurance in basic period of training we found variability of products in heptanes phase of lipid extracts
A little bit less there are works on protein synthesis, which is of great importance in plastic and energetic processes as well as in buffer component, which maintain the level of cations and reduce elastic viscous properties of skeletal muscles
Summary
Purpose: to scientifically substantiate effective mechanisms of organism’s bio-chemical adaptation of skiracers in competition period with the help of lipid peroxidation indicators, oxidative modification of proteins and activity of hypothalamus pituitary adrenocortical system. In assessment of ski racers’ metabolic state in conditions of concentrated development of local-regional muscular endurance in basic period of training we found variability of products in heptanes phase of lipid extracts It results in increase of aerobic share of energy supply [4]. Hypothesis: it is assumed that sportsmen organism’s integrative functioning in extreme environmental conditions is manifested in combined reflection of free radical lipids’ oxidation, antioxidant activity of blood plasma and protein synthesis All these in total determine energy supply, plastic and defensive functions of the tested sportsmen’s organisms. Organization of the research: we fulfilled laboratory testing of free radical oxidation, antioxidant system; we estimated activity of hypothalamus pituitary adreno-cortical system (determination of cortisol level) For this purpose we used quantitative analysis of indicators with bio-chemical methods, applied to blood serum samples. Determination of fluorescence intensity for quantitative detection of cortisol level was carried out with the help of bio-liquids’ analyzer «Fliuorat – 02 ABLFT » (Lumax, Sankt-Petersburg, Russia) with wave length of fluorescence excitation of 405 nm and emission 546 nm
