The reflection kinesiology analyse of cross country skiing
Chrástková, Martina ; Kračmar, Bronislav (advisor) ; Jandová, Soňa (referee) ; Dvořák, František (referee)
Title: The reflection kinesiology analyse of cross country skiing Purposes: To compare coordination of chosen muscles on leg during reflection of cross country skiing classic technique, skating and herringbone. Methods: Comparative analysis: the dates were measured by surface electromyography and 2-D video-analysis. Results: We founded statistical significance by comparisons muscle activation on right leg during kick during cross country skiing: classic technique, diagonal stride and herringbone and V-1 skating and herringbone. In case the left leg the statistical significance was disprove by: m. peroneus longus sin during comparison of diagonal stride and herringbone and m. gastrocnemius medialis sin V-1 skating and herringbone. We founded high level of laterality of diagonal stride and herringbone. In case V-1 skating, the significant similarity was not founded for m. vastus lateralis and m. gluteus medialis. Key words: Cross country skiing, classical technique, skating, herring bone, kinesiology, surface electromyography (EMG), muscles activation
Comparison kinesiology content move forward on the frame speed and padles ergometer
Charvátová, Alena ; Kračmar, Bronislav (advisor) ; Hošková, Blanka (referee) ; Jandová, Soňa (referee)
: The content of the following thesis was to determine whether locomotion through the shoulder girdle in our case, kayaking and paddling simulator, made the same timing of muscle involvement. Muscle loops run in a diagonal character and chaining muscle groups depending on the imposition of puncta fixa, proximal or distal . Locomotion research provided through the shoulder girdle will be made at kayaking, which is typical for this locomotion. Movement is carried trunk muscles, shoulders and upper limbs. There is, however, also activate the muscles of the lower limbs, motion pattern is becoming global and it also serves to link with the ship. The research objective was to determine the content of the kinesiology of movement while the frame forward to kayaking gear, and its comparison with other types of locomotion made through the shoulder girdle. According to the timing of muscle involvement can specify a "reference framework map of coordinating locomotion. Successive order to evaluate differences in timing of muscle involvement in different types of activities and determine the effectiveness of their use as training resources for performance paddlers. Electromyographycaly we watched the activity of selected muscles in repeated actions: typical human locomotion braiding shoulder, while kayaking and...
Monitoring of changes regarding muscle involvement in specific areas of human motion system when walking and nordic walking
Škopek, Martin ; Kračmar, Bronislav (advisor) ; Kučera, Miroslav (referee) ; Jandová, Soňa (referee)
The Dissertation is concerned with monitoring of changes regarding muscle involvement in specific areas of human motion system when walking and Nordic walking (NW) with focus on adults and by means of electromyography method. Within the process of field testing there were 9 randomly selected individuals at the age of 50 - 60 tested to elicit differences in the motion system. There was an effort to find certain differences within involvement of specific muscle groups in the area of shoulder girdle, pelvic girdle and lower limbs and retrieval of similarities of coordination attributes concerning locomotion at horizontal presented by paradigm of kinesiological content of reflexive crawling according to Vojta's principle. Kinematic analyses was used to discover a difference in involvement of specific muscles between Nordic (v = 5 kph) and regular walking (v = 4, 75 kph) up to 10˚ of ascent. Muscles where their MVC was diagnosed the difference in individual muscle involvement was monitored expressed in percentage. The values found were consequently related to their referential value of MVC and tested by means of Wilcoxon test for dependent selection. Muscles where MVC value was not diagnosed the intraindividual comparative analyses of activation muscle pair similarity was carried out on the grounds of...
Swimming technique of physicaly disabled swimmers with unilateral above-knee amputation
Čuříková, Lada ; Süss, Vladimír (advisor) ; Jandová, Soňa (referee) ; Fořterová, Petra (referee)
Headline: Swimming technique of physically disabled swimmers with unilateral above-knee amputation Aim of the Thesis: The aim of this thesis is to describe the intra-individual differences in the swimming technique of unilateral above-knee amputees by measuring the EMG of selected muscle groups. Methods: Surface EMG measurement in combination with using synchronized video recordings. Results: Research of the observed swimmers with unilateral above-knee amputation showed that: when swimming the front crawl, the swimmers unequally balance the intense kick of right and left leg mainly using the abdominal muscles and subsequently also in the electric potential of different sizes in other observed muscles; when swimming the backstroke, the upper body muscles on the side of amputated limb do not show any different activity than the muscles of the opposite side; when swimming the breaststroke, the main propulsion muscle for locomotion through the shoulder girdle - m. latissimus dorsi is activated for a longer period of time on the side of amputated limb; thereby, electrical activity of the selected muscles is not symmetrical in the timeline. Key words: swimming step, swimming, above-knee amputation, electromyography, muscle activity, handicap, EMG.
The Cuban revolution in international context from the beginning of the fifties to the beginning of sixties
Jandová, Soňa ; Nálevka, Vladimír (referee) ; Opatrný, Josef (advisor)
This work is dedicated to the political development in Cuba from the beginning of the fifties to the beginning of the sixties of the 20th century. This period is mostly known because of the Cuban revolution. The international relations between Cuba and the United States are the main interest of this thesis. AU chapters describe the most important incidents which affected Cuban history in this time. Because of the complexity of thís topíc, the history before the rise of anti-Batista opposition is also mentioned. The changes and reforms after the revolution did not only change the relations between Cuba and the USA, but affect relations in the whole region.
