Varijabilnost Biomehaničkih Parametara Troskoka - Studija Stručnjaka

Abstract

SUMMARYThe purpose of the study was to examine consistency and variability of kinematical parameters in the triple jump technique. An analysis has been carried out on the basis of two attempts of a female athlete who is one of the best triple jumpers in the world. The latest biomechanical technology and the methodology of measurements in the triple jump have been used. The Opto-track technology and 3-D kinematical technology were used in order to analyse parameters of the model technique in the triple jump. The study revealed that optimal result in the triple jump can be achieved with different programme motor strategies. It has been revealed that the motor pattern is generated by consistent and variable parameters. The most consistent parameters of motor pattern were: partial distances of individual phases, duration of support phases in take-off actions, take-off angles and vertical amplitude of BCM. Variability of motor pattern has been revealed mostly in the following kinematical parameters: speed in the last 5 metres of run-up, distance and proportion of the last two run-up strides, horizontal velocity of BCM in take-off actions.
