Richter, Michael ; Šteffl, Michal (advisor) ; Kinkorová, Ivana (referee)
Title: The effect of citrulline and citrulline malate supplementation on selected physiological indicators - review study. Objectives: Systematic findings overview of the effect of citrulline and citrulline malate on healthy individual's locomotor system and other physiological indicators. Methods: The study is designed as a findings overview. Electronic databases pubmed.com and ukaz.cuni.cz were used as an information source. "Citrulline" or "citrulline malate" and "exercise performance" and "randomized controlled trial" keywords were used for the information search. Results: Eighteen studies and 307 individuals are included in the overview. Studies are categorized according to duration and type of supplementation substance. Four studies agree on the strength improvement after acute use of citrulline malate. Four studies agree on endurance improvement in case of citrulline long term use. Three studies conclude on pain mitigation in case of substance use 24, 48 and 72 hours after training. Also, studies agree on increase of the levels of citrulline, arginine and ornithine plasmatic concentration after use of citrulline and citrulline malate. Three studies indicate possible fatigue decrease during the training in case of use of citrulline. Conclusion: Use of citrulline and citrulline malate can be...
The influence of alcohol on muscle contraction time in the thigh muscle area
Richter, Michael ; Šteffl, Michal (advisor) ; Kinkorová, Ivana (referee)
Name of thework: The alcohol influence on the rate of muscle contraction in the muscles of the thigh area Objective of the thesis: 1. The aim of the work was to determine the influence of an alcohol on contractile properties of muscles of m. Rectus femoris and m. Vastus lateralis in men and women. 2. Comparison of properties of postural and phasic muscles. Method: This is an empirical - theoretical work in which the research has the character of a quasi-experiment of a group of 22 probands of different genders with an experimental way of obtaining data. The experiment was applied on students that attend UK FTVS daily. The age of students ranged from 21 to 25 years. All students had to have a valid medical check-up and passed through a CAGE questionnaire that identifies alcohol addiction. The measurement was performed with the TMG 100, which serves to measure the contractile properties of the muscles. The muscles m.rectus femoris as representatives of postural musles and m.vastus literalis as representatives of phasic muscles, were chosen as examples. The research consisted of 4 rounds, where the first round was alcohol-free and the other three were with alcohol. Each round contained a dose of 0.3 grams of alcohol per kilogram of weight. For women this formula was modified. All results were...
