Differences in kinematics of the support limb depends on specific movement tasks of take-off

Background: Many sport activities are a sequence of jumps (running, jumping, hurdling etc.). Each jump flight phase is the result of the execution of the previous support phase. Objective: The goal of the research was to identify differences in adjustment of the support lower limb and differences in take-off kinematics in specific take-off movement task. Methods: 14 male athletes (22.6 ± 4.4 years; 182.4 ± 5.3 cm; 74.7 ± 6.2 kg) took part in a laboratory experiment. Each athlete performed five different take-off movements (running, acceleration running - second step, long jump take-off, high jump take-off and take-off to the hurdle). System Qualisys was used to analyze the kinematics of the support limb. Dynamics of the support phase was monitored via force plate. ANOVA and Bonferroni post-hoc test were used to measure the significance of the differences between different take off tasks. Results: Dynamic characteristic showed significant differences in take-off (p
