Title: Comparison of kinematic and dynamic characteristics of the running stride in barefoot running, minimalist shoes, spiked shoes and running shoes Objectives: The goal of this study is to determine how selected kinematic and dynamic characteristics of the running stride change with different types of footwear (shoes, spiked shoes, minimalist shoes) or when running barefoot. Methods: The measurements were conducted on 21 participants (active athletes competing in athletic disciplines for at least four years, capable of running in track spikes). A biomechanical analysis was performed using dynamometric plates and the Optojump Next optical device. The research was conducted on a long jump runway at the Faculty of Physical Education and Sport of Charles University, with each participant running a prepared 30-meter track 8-10 times at 80 % of their maximum speed. Statistical analysis was performed using the magnitude-based inference method. Results: Step frequency increased when running barefoot (shoes: 3.89 ± 0.23 steps/s, minimalist shoes: 3.90 ± 0.18 steps/s, track spikes: 3.91 ± 0.21 steps/s, barefoot: 3.94 ± 0.22 steps/s), step length shortened when running barefoot (shoes: 199.3 ± 7.5 cm, minimalist shoes: 200.1 ± 6.3 cm, track spikes: 199.7 ± 6.8 cm, barefoot: 198.8 ± 6.7 cm), and the flight...

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...
