Diet comparison of athletes from different types of gymnastics
Kudláčková, Tereza ; Vilikus, Zdeněk (advisor) ; Petráková Doležalová, Radka (referee)
Gymnastics is an aesthetic sport in which the emphasis is placed on optimal physical appearance. However, this is often associated with maintaining an inadequately low body weight, which can have a negative impact on both health and sports performance. For some of its features, gymnastics is thus found to be one of the possible risk factors for eating disorders. When it comes to the teenage population of female athletes, the aforementioned issue becomes even more important. Teenage gymnasts between the ages of 15 and 18 from two gymnastic sports, rhythmic gymnastics and aerobic gymnastics, participated in the research carried out as part of this diploma thesis. The aim was to find out whether the diet of gymnasts differs depending on the different sports and whether these gymnasts consume food adequately both in terms of its quantity and quality. For this purpose, the gymnasts recorded their food intake, while the 4-day food records provided by 8 representatives of rhythmic gymnastics and 8 representatives of aerobic gymnastics were subsequently evaluated. Based on the average of 4 individual days data and comparing the results with the recommendations, it was found that the diet of the gymnasts was insufficient from an energy point of view. On average, the participants did not reach the...

Fitness center clients nutrition focused on protein and magnesium intake
Pajič, Barbora ; Vilikus, Zdeněk (advisor) ; Petráková Doležalová, Radka (referee)
The diploma thesis deals with the importance of protein and magnesium in the diet of recreational visitors to fitness centers. Excessive protein intake at the expense of other macronutrients is a very common phenomenon in the fitness sector. Magnesium is an important element for muscle regeneration and its deficiency can have a negative effect on weight reduction and muscle gain, leading to fatigue and cramps, which many athletes encounter. As visits to the fitness center become more and more popular nowadays, it is important that athletes are not subject to misleading and confusing information from the internet and look for proven sources. The aim of the diploma thesis was to compare eating habits, especially protein and magnesium intake, in two groups of people divided according to the frequency of training in the fitness center. This work is divided into theoretical and practical part. The theoretical part deals with nutrition in the fitness industry in general, but more attention is focused on proteins and magnesium. Quantitative research using a questionnaire survey was chosen for the practical part of the work. A total of 30 respondents participated in the research, divided into two groups - athletes and non-athletes. Non-athletes were considered to be those who have two or fewer workouts per...

Eating disorders at ski jumping athletes
Ptáčková, Veronika ; Vilikus, Zdeněk (advisor) ; Petráková Doležalová, Radka (referee)
In my bachelor's thesis I have been dealing with a risk behavior in the field of nutrition of Czech men and women ski jumpers. The goal of the bachelor's thesis was to find out whether Czech men and women ski jumpers maintain their physiological weight, whether they use inappropriate practices (for example, induction of vomiting) in the context of weight loss. I also investigated whether there is an effort of the International Ski Federation to reduce the risk of eating disorders among athletes engaged into this discipline. In the theoretical part of this bachelor's thesis, I focused on individual types of eating disorders, risk factors for their occurrence, health complications associated with eating disorders or the epidemiology of these disorders. Furthermore, I focused on the ski jumping itself, explained the rules, especially those concerned about the weight of jumpers. I found out how important is the weight of the jumper in the final length of his jump. I also focused on the development of body weight of professional ski jumpers. The practical part was realized in the form of own designed non-standardized questionnaire. The questionnaire was filled in by 49 respondents, 17 women and 32 men. According to the BMI, a third of respondents are underweight, more often women (55 % of women). A...

Kvízová, Anna ; Vilikus, Zdeněk (advisor) ; Petráková Doležalová, Radka (referee)
The bachelor thesis deals with the influence of the combination of dietary supplements on the body composition of single-sex twins with comparable sports activity. The theoretical part of the thesis includes nutrition from the general point of view and the importance of individual macronutrients and micronutrients in sport. There are mentioned also selected types of sports nutrition supplements, which are widely used in order to support nutrition to achieve better performance, better recovery after sports performance, muscle tissue growth etc. The theoretical part deals with the nutrition of individual population groups from inactive individuals to the top athletes. The practical part of the thesis focuses on research aiming at the detection of the difference in body fat loss, the increase in body muscle mass and the increase of the basal metabolic rate in single-sex twins for three months. Nowadays, many individuals, especially women, are considering whether to add supplements to achieve better results and performance even though they do not train at the same level as top athletes or high endurance ones. Throughout the research, both subjects had the same diet regimen, a training program, the only difference was in the use of specified supplements in one of the twins (subject 1). To determine body...

Change in bodyweight and body composition during the weightlifting training unit and nutrition in strength sports
Vašků, Karolína ; Matoulek, Martin (advisor) ; Petráková Doležalová, Radka (referee)
This bachelor thesis monitors changes in body weight and body composition during training in professional athletes, three women and four men, from the Czech weightlifting team. The theoretical part describes components of the body composition, basic methods and calculations for its assessment. In addition, energy substrates used in weightlifting and sport nutrition basics, including suitable supplements for power athletes, are mentioned. In the practical part, using the bioelectric impedance device, we evaluated the actual body composition and energy needs of individuals in a series of three defined measurements-before training, after training, and after meals. The results of our qualitative research confirm that the energy needs of power athletes are far higher than predicted. We compared the minimum caloric requirement values obtained with the In Body 230 device measurement to those obtained using the Harris-Benedicts predictive equations (HBE), and pointed to significant deviations in basal metabolism calculations and inaccuracy of the results obtained with this equation. In most cases, with HBE, we have experienced undervalue in comparison to the In Body measurement. We have also confirmed the fact that the BMI is not suitable for the weight loss evaluation in weightlifters because of the...
