THE INFLUENCE OF CREATINE MONOHYDRATE ON THE INDICATORS OF SPEED ENDURANCE AND CHANGES IN THE LEVEL OF BIOCHEMICAL INDICATORS IN FOOTBALL PLAYERS

Abstract

The relevance of the research is to maintain an optimally high level of activity of energy supply systems for muscular work and special physical performance with the help of ergogenic means for football players in the process of competitive activity is an urgent problem in sports of the highest skill level. The aim of the research is to study the effect of multiple intake of creatine monohydrate for 28 days by football players at a dose of 0.1 g/kg of muscle mass on speed endurance and biochemical parameters after a test load. After passing bioimpedance measurement and calculating the doses and implementing them into the training system of football players, research results were obtained. Statistically significant difference in the test among football players from the Experimental Group indicates a clear improvement in the level of speed endurance. The obtained data of other indicators are also indicators for inclusion in the daily diet of taking this ergogenic agent. The reduction in lactate, creatinine, and CK levels after 4 weeks of creatine monohydrate supplementation suggests that supplementation may also be effective in both increasing training volume and post-exercise recovery. Based on the data obtained, it was clearly shown how taking 28 days of creatine monohydrate at a dosage of 0.1 g / kg of muscle mass per day significantly increased performance in a test exercise (increase in the number of steps) by 8,29% and affected biochemical parameters after a test exercise, where creatinine values were lower by 3,50%, CK values by 7,20%, and lactate concentration after exercise decreased by an average of 18,00%.
