Dependence oftheair consumption and thepositionofthe body on theselectedmethodofdivingkick and swimming speed
Ehl, Sebastian ; Vondrášek, David (advisor) ; Bačáková, Radka (referee)
Title: Dependence of the air consumption and the position of the body on the selected method of diving kick and swimming speed Objectives: The goal of this work is to find out the relationship between the diver's swimming speed and the air consumption while using two different methods of diving kicks - flutter and frog kick. At the same time, assess the dependence of the position of the body and head on the swimming speed and method of diving kicks. Methods: In this work was used method of collecting data in real conditions by measuring devices and statistical evaluation of collected data. Results: The results are presented by graphs both in the text of this work and in attachment for its large size. The results of all probands are presented in summary graphs and for selected values the degree of association is calculated in tables using the Pearson correlation coefficient. The main result is the confirmation of the reduction of the deviation from the horizontal position when comparing the slow and higher swimming speeds of both flutter and frog kick. The most effective way for a diver to overcome 50 meters below the water surface was determined to be a flutter kick at medium speed (average 0,37 m/s). Keywords: scuba diving, body position, head position, air consumption, speed of swimming, flutter...

Analysis of the motion and position on the movement of the human body during scuba diving
Ehl, Sebastian ; Vondrášek, David (advisor) ; Bažant, Filip (referee)
Title: Analysis of the motion and position on the movement of the human body during scuba diving. Objectives: The goal of this work is to find out which movements our body, as a complex mechanism, does during diving with diving equipment. The statistics was made with five probands in the set of six measurements. This statics supposed to show us what effect does speed of swimming on body possition when the flutter kick or frog kick is used. The move in frontal and vertical axis of the swimmer will be evaluated in both style of swimming, also the observational error will be evaluated. The goal of this work is not to messure exact angles but how those angles changes according to speed of swimming. Last but not least will be determined the conection between speed of swimming and body position. Methods: For this work was used method of collecting data in real conditions by measuring device and statistical evaluation of collected data. Results: Results are presented by graphs where are the measured data of all probands. These data are compared with each other and added to another graphs. In tables there are correlation coefficient for link between size of angel and velocity of swimming under water surface. It was found that with high association the size of angle between the axis of the body and the...
