Objective of the study was to assess the effects of the creatine monohydrate- and glucose-based dietary supplements on the hypertrophy of muscle tissues, development of strength and strength endurance in bodyfitness.
Methods and structure of the study. The educational experiment involved the 18-25 year-old athletes divided into 2 groups: Experimental (n=15) and Control (n=12). We analyzed the dynamics of changes in the athletes’ strength and strength endurance rates, as well as their body mass throughout the training process.
Results and conclusions. The test rates were found to significantly progress at all stages of the educational experiment, which suggested the effectiveness of the proposed training method and the positive influence of the course intake of dietary supplements on the hypertrophy of muscle tissues, development of strength and strength endurance of the athletes. The comparative analysis revealed statistically significant differences between the EG and CG athletes, thus confirming the hypothesis that the course intake of the creatine monohydrate- and glucose-based dietary supplements considerably accelerates the hypertrophy of muscle tissues and development of strength, as well as contributes to the development of strength endurance in bodyfitness. The findings proved the effectiveness of the course intake (18 weeks or more) of the creatine monohydrate- and glucose-based dietary supplements. In particular, the effective medication regimen was as follows: for creatine monohydrate – from 8 g per day (first 2 weeks) to 3-4 g, for glucose – 5-8 g per 1 kg of body mass.

Keywords: dietary supplements for sports, creatine monohydrate, use of glucose in sports, hypertrophy of muscle tissues, development of strength and strength endurance.
