Effect of trunk stabilization on throwing velocity in heptathlon and decathlon athletes
Hanuliaková, Júlia ; Žáková, Lenka (advisor) ; Stupková, Michaela (referee)
Title: Effect of trunk stabilization on throwing velocity in heptathlon and decathlon athletes Background: Throwing disciplines are an important part of combined track and field events. A stable trunk is a necessary component of the kinematic chain in the generation of force during throwing. Throwing is usually ineffective if the leg and trunk muscles are unable to generate sufficient force or if there is no transfer of energy to the throwing arm. This paper examines the effect of trunk stabilization on throwing velocity. Objective: The aim of the study was to investigate whether it is possible to increase the throwing velocity of heptathlon and decathlon athletes by using exercises aimed at improving trunk stabilization. Methods: Measurement of throwing velocity using sports radar, assessment of trunk stabilization level using Janda's stereotype of push-up, Kolar's bear test and deep squat test and McGillʹs torso muscular endurance test battery. Results: During the ten-week intervention focused on trunk stabilization, the experimental group experienced an average improvement in throwing velocity of 5.76 km/h (8.9%). The control group, continuing with standard training, experienced only a slight improvement in throwing velocity of 1 km/h (2%). In the evaluation of trunk stabilization, the...

BACHELOR THESIS ABSTRACT First name and surname: Júlia Hanuliaková Supervisor: Mgr. Silvie Táborská Title of the bachelor thesis: The importance of core stabilization for track and field throwers Abstract: This bachelor thesis deals with throwers' core stabilization in athletics. Theoretical part described basics of throw, individual throwers' athletic disciplines, factors influencing sport performances, postural functions and core stabilization. Practical part includes case studies of three probands. Target group was created by young athletes competing in at least one throwers' discipline. Therapeutical intervention was focused on improving core stabilization and took 10 weeks with therapy 2 times a week. The results were analysed based on examination of postural stabilization according to Kolář, chosen functional test and comparison of best achieved results before intervention in seasons 2019, 2020 and 2021 to best achieved results after intervention in season 2021. The aim of this bachelor thesis is to evaluate how did the performance of track & field throwers changed after the intervention focused on core stabilization. Furthermore, to create a training unit and increase awareness about core stabilization and its' influence on sport performance of track & field throwers among trainers and the sportsmen...
