The Doctoral thesis concerns development of a computer model of start in the sport of luge and development of cameras’ calibration procedure, which can be implemented at the athletes’ competitive and training environment. The Thesis is organised as follows: justification of choice of the topic and its relevance is included in the Introduction together with objectives and rationale of the research. Validation of the scientific novelty and practical applicability of the research is also included in the Introduction. In the first chapter a general description of bobsleigh, skeleton and the sport of luge (the sliding sports) is given on the basis of the available sources. Current research state and general conclusions from the studies conducted in the sliding sports during 1978 – 2011 are provided. The chapter also includes a detailed description of start performance in the sport of luge, the concept of kinematic chains in sports biomechanics, description of the motion capture method, computer modelling and computation of body inertia parameters in sports science. The second chapter provides information on equipment and methods used in the study and the research material collection procedure. Also included is justification of the new calibration approach development and essence of camera calibration procedure. In the third chapter the achieved research results are discussed and the developed models are described in detail together with their applicability analysis. Conclusions include formulation of the results and general achievements of the research. Appendices contain additional information and descriptive materials. References present the list of sources used throughout the Thesis (including period from 1978 till 2012). The doctoral Thesis is written in Latvian, includes 124 pages, and contains 54 figures, 18 tables, 147 references and 9 appendices on 42 pages.
