The effect of beta-alanine supplementation on aerobic exercise in adolescent athletes
BAHENSKÝ, Petr
Supplementation is generally increasingly popular at this time, so the aim of our bachelor thesis was to explore in more detail the effect of beta-alanine supplementation on aerobic load in adolescent athletes. We looked at how beta-alanine affects the performance and endurance of young athletes during physical activity. In total, 20 young athletes participated in the study, of whom 8 were boys and 12 were girls. They underwent two staged exercise tests over a four-week period. The athletes were randomly divided into two groups: the experimental group that supplemented beta-alanine and the control group that took placebo. The results showed that after four weeks of beta-alanine supplementation, there was a significant improvement in the overall time to exhaustion. Specifically, an increase of 7.4 % was observed. The running rate at the second ventilation threshold increased by 5.7 %. An important aspect was also the blood lactate value, which increased by 8.8 % three minutes after the end of the test. This increase in lactate suggests that beta-alanine supplementation resulted in greater exhaustion, resulting in increased lactate production. Next finding was that other parameters such as VO2max, maximum heart rate and final respiratory exchange rate did not change significantly. This indicates the specificity of the effects of beta-alanine under aerobic load in adolescent athletes. In conclusion, the results of this bachelor's thesis suggest a positive effect of beta-alanine supplementation on aerobic load in young athletes. This dietary supplement can be a useful tool for improving endurance performance and achieving better sports results in this specific group.

Effect of changes in training load on the motor performance of young distance runners
Bahenský, Petr ; Kampmiller, Tomáš (referee)
Subject The performance in sport is created by the amount of talent and also by experienced training, but the relation between the training and the performance has a likelihood character. Generally, a long-distance talent is determined genetically from 70%. Reaching the top level is conditioned by both factors on top level. Therefore, it is very important to choose the right suitable training strategy at teenage runners, which can lead to optimal performance growth, concerning the individual age unusualness and talent. The higher performance was proved at specific training more than at nonspecific training. Meaning of nonspecific training is especially at young runners and beginners. The training effect becomes evident after some time, it has a latent effect. One of the most important factors of the final performance is also the economy of movement. Objectiv The aim of the thesis is to evaluate training changes in comparison to training load at teenage talented runners with the help of longitudal ex-post facto study. Methods The thesis deals with analysis of sports training at chosen athletes - runners at young age. It comes out of the need of long-term, systematic, perspective sports training, preferably corresponding with age. We deal with the influence of changes in volume and intensity during...
