Sport Biomechanics Research Project at IAAF World Championships Daegu 2011

Abstract

The purpose of this study was to find the biomechanical research project result carried out at 2011 IAAF World championship in Daegu. This project was approved by the International Amateur Athletic Federation(IAAF) and financially supported by the Ministry of Culture, Sports and Tourism(MCST) and, Korea Association of Athletics Federations(KAAF). The total number of the project members was 20, including the members of the Scientific Committee, the Korean Society of Sport Biomechanics(KSSB) and graduate students as assistants. The objective of this project has been to analyze the performance in the track events(100 m, 110 mH) and field events(Long Jump, High Jump, Triple Jump, Pole Vault, Javelin Throw and Shot Put). This project was focused on the biomechanical research only. This kind of analysis has been carried out at major competitions for more than a decade, as it provides coaches and athletes with very useful information as an aid to training programmes and competition preparation. The biomechanical analysis of the top athletes in the world in each specialty serves as a reference for assessing technique and rationalizing the results achieved. The results will be disseminated worldwide and coaches will be in a better position to design training strategies in line with current world trends.

An Examination of Approach Run Kinematics in Track and Field Jumping Events

“…It is well documented that the velocity of the last step before the take-off is usually higher in comparison to the velocity of the penultimate step [8,15]. Support for this conclusion is provided by the findings of the present study in all analysed events.…”

“…Based on previous studies [8,15], it was expected that the long jumpers would produce the highest mean step velocity during the approach run and the pole vaulters would produce the lowest one [14]. Nevertheless, there was a lack of explanation for this difference between long jumpers and triple jumpers.…”

The Impact of Push Phases Takeoffs Angles on Performance in the Dominant Hop Technique

“…For the purposes of analysis, we have explore the report IAAF (International Association of Athletics Federations) indicate in the references of Project by the German Atletecs Federration (2009) [8] and (Young-Sang Bae, Young-Jin Park, Jong-Jin, Park, Joong-Sook, Lee, Woen-Sik, Chae, Seung-Bum, Park (2011) [9] as repair to Extraction Angle of take-off (˚) push phases for our samples. For the experimental conditions, we have taken the results of the contestants in the two competitions (2009-2011) with the above-mentioned application of the same distribution model.…”

Análisis de la carrera de 100 metros lisos mediante la evaluación del deportista con sistema láser y plantillas instrumentadas

“…En la final del Campeonato del Mundo (Daegu 2011) la atleta ganadora descendió su velocidad, a partir del tramo de 80 m, un 4%, y del 90 al 100 en un 6.74% (Bae et al, 2011).…”

“…Igualmente las plantillas instrumentadas han sido aplicadas en contadas ocasiones para el análisis de deportistas de velocidad (Berna y Cortés, 2013;Elvira, García, Meana y García, 2008;García-Pérez y Lucas-Cuevas, 2012;Salvador, García, Iranzo, Pérez-Soriano y Llana, 2011;). Es por ello que vimos el interés que podría suponer el trazar (Bae et al, 2011;Bruggemann, Koszewski y Muller, 1999;Graubner y Nixdorf, 2011;Matsuo et al, 2007;Ryu et al, 2012). No ha sido así en el caso de las plantillas de presión plantar.…”
