Title: Changes in biomechanical parameters of the running stride during model training of a special pace 800 m runner (in the preparatory and competition period) Objectives: The aim of this pilot study was to determine the dynamics of changes in selected biomechanical parameters and then to compare these changes in probands over a 2- month period based on baseline and outcome measurements. Methods: The measurements were performed on three probands, each proband representing a different type of runner (novice athlete, recreational athlete, performance athlete in the national under-23 team). Qualitative analyses with the Optojump device were used. The research was carried out in a pressurized hall in Strahov on an indoor 200 m track in two measurements. The first measurement represented the end of the preparation period and the second the competition period. The probands completed the so-called model training (300 m and 200 m) at a special pace with a one-minute break between sections. During the selected sections, biomechanical parameters were collected by Optojump equipment on an indoor 200 m track in 10 m corridors. Results: Proband 1 improved by 3.1 s over 300 m and by 2.1 s over 200 m in the output measurements of the model training. This improvement was reflected in a 0.006 s reduction in...
