Title: Application of backstroke to a patient with ankylosing spondylitis Objectives: To evaluate the effectiveness of the application of backstroke with chosen parameters to a patient with ankylosing spondylitis. To compare the effectiveness of this swimming exercise programme with a traditional exercise programme held in a gymnasium. This work investigates whether it is suitable to recommend backstroke swimming to patients with ankylosing spondylitis as an effective form of physical exercise for improving range of movements and reducing pain. Methods: The effectiveness of a 9 week long swimming programme was evaluated using a range of movements of the glenohumeral and coxal joints and of the spine. The presence of pain was measured by the Bath Ankylosing Spondylitis Diasese Activity Index. The same parameters were measured for another patient with the similar activity of the disease who took part in group exercises in a gymnasium. At the end of the programmes the parameters were compared and evaluated. Results: The swimming programme has improved the patient's posture and has strengthened back muscles. Pain was reduced in some parts of the back and also general pain measured by BASDAI. The range of movements of both glenohumeral joints improved in all measured directions. The range of movements...

The primary purpose of this study was to gain a better understanding of the turn interval and the factors that influence turn performance. A secondary purpose was to investigate the relationship between turn time, the components that influence turn time, and performance in competitive swimming. Fifty-eight swimmers (24 female, 34 male) from four NCAA Division I schools were videotaped in the 100 and 200 yd freestyle and backstroke events during three collegiate competitions. The freestyle was shown to be significantly different from the backstroke in race time, turn time, and time during the in phase of the turn for both genders in the 100 and 200 yard events. Significant positive correlations were found between turn time and race time across both genders and all four events. Inspecting the velocity curves of the turns allowed the key outphase variables to be defined. Turn time is an important determinant of race time in collegiate swimming. Using the dolphin kick technique during a turn causes large fluctuations in velocity during the active glide phase of the turn. / School of Physical Education

TEACHING OF BACKSTROKE SWIMMING YOUNGER SCHOOL AGE CHILDREN Objectives: The main objective of this thesis is to create a digital video recording of a contemporary teaching method of backstroke swimming technique with younger school age children. A group who are from 6 to 9 years old participate in the research work. Methods: In this thesis we have in the first and second phase focused on collection datas from the literature and its other processing into a methodical series of exercises. In the third stage we used the Scenarios for video processing. Results: Findings of the thesis indicate a possible procedure for teaching backstroke swimming style with younger school age children. Keywords: didactics of physical education - swimming, backstroke, younger school age

Name: An overview of the performance of men and women in the discipline of the 100 m freestyle at the Olympics from 1924 to 2016. Aim: The first aim of the diploma thesis is to create a historical overview of the course of swimming competitions at the modern Olympics from 1924 to 2016. The second aim is to process personal profiles of male anf female swimmers at the first places in the discipline of the 100 m freestyle from 1924 to 2016. And the third aim is to compile a performanceoverview of all male and female finalists in the discipline of the 100 m freestyle after two always following Olympics from 1924 to 2016. Methods: The historical method was used in the search for sources of historical data in the development of swimming and the processing of individual Olympic Games. It consisted of analyzing historical facts, examining sources and creating an overview of developments. Based on the search and processing of individual performances, graphs were prepared and then the results were compared. Outcome: From the analysis of performance, we found that in the period from 1924 to 2016, men improved by 19%, which represents 11.42 s, and women by 27%, which is 19.70 s. The results of the research show that the development of men's performance slowed down while women's performance is still improving....
