The impact of technical training - alternating circling the upper extremities - to crawl swimming stroke of FPES students
Hejkalová, Barbora ; Jurák, Daniel (advisor) ; Pokorná, Jitka (referee)
Title: The impact of technical exercise - alternating circling of the upper extremities - to technical part and performance of swimming style crawl, observed in Charles' University students of the Faculty of Physical Education and Sport Objectives: The aim of this thesis is to determine whether the exercise alternating circling of the upper extremities in standing applied during the swimming lessons has impact on improving technically swimming style crawl. Methods: The research involved 28 probands of the 1st degree of Faculty of Physical Education of Sport Charles University who have never taken part in swimming training. During the research was used only non-invasive methods. The measurement of height of body, upper extremity range and body composition on TANITA device. Testing was carried out in the laboratories of sports motorics at Faculty of Physical Education of Sport in Charles' University. Than testing in swimming pool was attended a swimming test at the distance of 25 and 50 m. Probands were testing in time and it was calculated number of strokes in a swimming test at the distance of 25 to 50 m. Results: Based on testing, we can say that intervention of the exercise alternating circling the upper extremities in probands of intervention group had a statistically significant reduction in...

Comparison involvement of muscle groups in the circular movements of the upper limbs on land and in water
Hejkalová, Barbora ; Jurák, Daniel (advisor) ; Miler, Tomáš (referee)
Title: Comparison involvement of muscle groups in the circular movements of the upper limbs on land and in water Objectives: The aim of this thesis, is to determine the muscles aktivity inside the water and out of the water. Methods: This is a pilot experimental study, which was done on one proband. Proband was a man - in the past professional swimmer. The surface EMG muscle activity was scanned on selected muscles during the circular movements by upper limbs on the land when the proband stand up and in the water where proband swam by crawl technique. Both movemenets were done by the same speed. The EMG signal was then analyzed and evaluated the average of muscule maximum voluntary contraction (MVC) and average of muscules working during the circular movement out of the water and inside the water. The results were compered each other. Results: Based on the measurements, we can conclude that, the muscle activity is the same in both of the examined muscles, M. Obliquus external and M. Thoracic erector spinae. Other muscles M. Deltoideus clavicularis, M. Triceps brachii, M. Trapezius ascendens and M. Trapezius descendens work differently, the variation can be between 1 /3 to 1 /5 of muscle aktivity higher out of the water. The only muscle that works on land with a lower intensity than in water is M....

Swimming performance of modern pentathlonists in U15 category in the years 2010 - 2015
Szmek, Marek ; Chrzanowská, Babeta (advisor) ; Kramperová, Veronika (referee)
Title: Swimming performance of modern pentathlonists in U15 category in the years 2010 - 2015. Objective: The aim is to determine whether after 2010, when it was started the cooperation of the Czech Union of Modern Pentathlon with swimming sections, there was a positive change in the level of swimming performances of youth category U15 in the years 2010 - 2015. At the same time determine, whether was lifted memberships of modern pentathlonists (the number of clubs, the number of competitors). Methods: Comparison method for comparing performance results, the method of mathematical and statistical for processing of obtained data. Results: We found, that the swimming performance in modern pentathlon, due to this cooperation, in the surveyed category U15, has not improved. Furthermore, we found, that the influence of this cooperation between the Czech Union of Modern Pentathlon and chosen Swimming clubs, has lifted the number of competitors, who actively participates in the modern pentathlon competitions. Keywords: Swimming, crawl, stages of training, modern pentathlon disciplines, performances.

The impact of the exclusion of the visual analyzer on the swimmerś ability to swim straight while doing the crowl
Štouračová, Andrea ; Kovařovic, Karel (advisor) ; Břečková, Gabriela (referee)
Title: The impact of the exclusion of the visual analyzer on the swimmer's ability to swim straight while doing the crawl Goals: The goal of this work is to determine the impact of the exclusion of the visual analyzer on one's ability to swim straight while doing the crawl; to find and analyze the angle of the deviation from the set central line, if any, using measurable variables; to find the critical spots in the fulfillment of a set movement assignment where the swimmer deviated from his straight swimming direction, to make a qualitative analysis of these spots in relation to the individually optimal technique, and to propose potential corrections of the time and space of movements of the upper limbs work and the body. Methods: A qualitative analysis with a manual measurement of the deviation from the straight direction of swimming per constant distance. Analysis of a video- recording to find the critical points in the crawl technique. Questionnaire to deal with participants' upper limbs laterality. Results: We managed to determine some causes of the deviation from the straight swimming direction without visual control. The achieved results proved that breathing was an important aspect when doing the crawl having influence on the ability to swim straight: The impact of laterality on the...
