Abstract
The aim of this thesis is to carry out kinematic analysis of sprint running and analyse the relation between various physical ability tests and sprint running performance on the sample of Estonian sprinters. The researched sample consists of 33 female and 38 male Estonian best sprint runners and hurdle sprint runners. These athletes participated in sprint and physical ability testing within the period of 2005-2008. The following tests were used to measure the physical ability: jumping tests (standing long jump, countermovement jump and standing five-step jump), running tests (30m from blocks, 30m from flying start, 150m from blocks) and throwing test (shot throwing). The stride frequency and length and contact time were measured based on 30m flying start running.
The thesis finds that the foot contact time, stride frequency and length and running speed are strongly correlated; the strongest correlation is between the foot contact time and stride frequency (p<0.001 for male and female sprinters). The stride frequency is more important kinematic characteristic than stride length in maximal speed sprinting. The stride frequency and stride length are strongly negatively correlated. Estonian male and female sprinters lose substantially to world top level sprinters in stride frequency. Estonian female sprinters lose also substantially in stride length. The standing five-jump test is the most informative physical ability test for the assessment of athlete’s sprinting ability. The shot throw test is the most informative test to assess the acceleration speed ability.
