(In English): This master's thesis examines the type and frequency of activities on social networks and video games with an emphasis on activities that support the objectification of one's own body or are in direct connection with it. The aim of this study was to evaluate the impact of these activities on the Czech national-wide sample, focusing on respondents who show signs of eating disorders. The evaluation was based on a questionnaire survey of more than 1000 respondents and the results were analyzed mainly by using contingency tables. Based on the results of this research, it is not possible to confirm a direct relationship between self-objectification and ways of new media usage, but some activities correlate directly with people who show an unhealthy relationship with their own bodies. In conclusion, specific steps are proposed for a more suitable survey of self-objectification and recommendations for further research.

Title: Evaluation of actual state of children locomotor system for students of primary school. Objectives: Determine the current satus of locomotor system of children of primary school age by assessing a body posture of chosen sample of children and create compensation exercises for school and after-school physical education moments. Methods: We used the method of aspection in which we were watching deviations in body posture of different parts of body and their mutual position in sagittal and lateral view with using the test of Jaroš and Lomíček, Klein and Thomas. Results: We found out that within the chosen sample more than half participants have a correct body posture. Nevertheless, 48,5 % of participants have defective body posture. Weakening occurred primarily in the abdominal area and pelvis, in the back curve and when looking from behind a lot of participants have left to stand shoulder blades. Keywords: physical education moment, poor body posture, muscle imbalance, compensatory exercises.

Title: The influence of equipment and arms on skeletal muscles activities while practising direct kick. Aim: The aim of this thesis was to find out the influence of carried equipment and arms on the activity of skeletal muscles when a direct front kick is being practised. The methods used: This thesis has an empirically observational character. Muscular activities were measured by means of surface electromyography synchronised by Qualisys screen system. To obtain statistic data, a t-test has been used, requiring 5 % significance level. Results: While carrying a 15-kilogram load, the activity of skeletal muscles was not significantly reduced when performing a direct front kick. However, a 30- kilogram load caused a substantial reduction of skeletal muscular activities during the kick described above. After adding a 15-kilogram bag to another 15 kilograms in the form of a body armour, a helmet and arms, the muscular activity changed its features in a considerable way. Furthermore, most respondents proved 45-kilogram load to be over their limit. The equipment and arms of that weight led to the summation action potential, exceeding the power- coordinative functional reserve, and thus the deformation of the direct front kick technique. Keywords: close combat, EMG, equipment, arms, direct front kick

in English A beautiful and healthy body now indicates a happy and contented life, and that is why our society is so obsessed by it. It was transformed into a commercial object, and the borders to which we can manipulate with it are pushed even further. At the same time, many people realize the necessity of cooperation with the body in order to reach a physical and mental health. Voices are heard calling for prevention of exploitation of human bodies and against the lowering of human dignity. We can see showing up different kinds of oriental philosophy, psychosomatic medicine or psychoterapeutic approaches targeted at the body, which are trying to outweigh the trends treating the body as a mere commodity. In spite of those efforts, the number of people with impaired perception and experiencing of their own body is still growing. The most frequent and most discussed are the eating disorders, which endanger seriously all aspects of a person's life. Most of the disorders will develop during adolescence, and that is why in my research I focused on the mapping of corporal experience of young people. In my work I employed the grounded theory method, or a qualitative research. The main research method used is semi-structured interview. The theoretical part consists of a philosophical historical and social...

Background Pes planus is one of the most common diagnoses in the pediatric field; flexible flat foot being the most prevalent. This developmental type of flatfoot is a normal finding in young children, seen to resolve spontaneously with growth and development and also remain asymptomatic. Despite this, there is still a large incidence of flat feet in adolescence and many cases of adult flatfeet are frequently presented as residual pediatric flatfeet. The factors that influence the prevalence of flatfeet during a child's development have also the capacity to altering its course and gaining insight on what they are and their influence aids in diagnosing, treating and preventing flat feet. Purpose The aim of this literature review was to enhance knowledge on the persistence of the flat feet condition in the pediatric population by determining the development of flat feet in children with an outline of its affect on posture and gait and identifying contributing factors that affect the incidence and progression of the deformity. Methodology An electronic database search was conducted to obtain articles from relevant journals (from early 2012 to mid 2013). Only full text English articles were obtained, with a few exceptions. Further information was collected from online textbooks and the reference lists of the...

The objective of this thesis is to examine the presence of the poor posture or the muscle imbalances at younger school-age children. Children do actively sports in a ski club for a long time; they also have a year training plan. Stationary functions and muscle activity in physiological position were investigated by physiotherapist who indicated some poor posture and muscle imbalances. On the basis of that examination there were recommended some compensatory exercises that can help to adjust or to eliminate detected imbalances. Recommended exercises became a part of the club training program, but the main part was practiced at home. According to the entrance and final examination of the participants we can assess the positive influence of the compensatory exercises to muscle imbalances and the children musculoskeletal system. Considering the results of the thesis we are able to proclaim that the long-term exercises can completely eliminate muscle imbalances. The contribution of this thesis has an irreplaceable importance for the work with children in the ski club.

Title: Postural stability of school age children Objectives: The purpose of this work is description of selected postural stability parameters of school age children population and evaluation of sensomotoric stimulation and ball excercises effect on the postural stability. Methods: This work is a descriptive work with included intervention. During the study, four groups of 10 and 11 year old children were examined, each group had 21 members (n=84; average height=148,2 ± 5,67 cm; average body weight=37,4 ± 4,29 kg, average age=10,96 ± 0,69 years). All 84 children participated in the first measurement on a Footscan to evaluate the level of postural stability based on the selected parameters. Then 15 children were chosen for a 5 week long intervention. After this intervention the group took the measurement again. The final number of children tested in this work was 12 (n=12; average height=151,7 ± 4,61 cm; average body weight=39,71 ± 2,99 kg; average age=11,43 ± 0,29 years). Outcome of the first and second measurement was compared and processed. Results: Most of the selected parameters have shown, that girls have better postural stability than boys of the same age and that 11 year olds have better postural stability than 10 year olds. The parameter TTW (Total Traveled Way) was chosen for the...

Title Impact of gear and weaponry on posture in kneeling shooting position Objectives The aim of this thesis is to find out the impact of gear and weaponry on posture in the kneeling shooting position. Specifically, this study examines the influence of carried load on posture, aiming stability and balance in the high and low kneeling shooting position variants. Methods This thesis has an empirical observational character. The shooting position was tested by Qualisys camera system and Kistler pressure plates. The measurment was performed on 16 Military department students with mean age of 23 years (standard deviation 2,63 years). Measurements were carried out in four levels, with no load, light load of 15 kg, mean load of 30 kg and heavy load of 45 kg. The measurement was performed on high kneeling variant and the low variant with elbow supported by the front knee. Intra-individual comparison of the results of each level was determined by a T-test. Results: The load in a form of gear and weapony had a statisicaly significant - negative influence on the kneeling shooting position posture. Gear and weaponry used for this study caused a lower trunk position, increased shoulders angle in the low variant, lesser aiming stability and balance control in the position. The bigger was the weight of gear and...
