PRESSURE DISTRIBUTIONS ON THE PLANTAR SURFACE OF THE FOOT DURING THE JAVELIN THROW

The aim of this study was to compare the plantar pressures and forces recorded from both feet of two groups of javelin throwers of different performance levels, in order to investigate differences between skill levels. The study was carried out using an EMED insole system on a Ta rtan javelin runway at the University of Innsbruck, Austria. Most of t he differences (at p < .01) between the two groups were found in the t wo foot contacts during the delivery stride. Higher maximum total forc es (forces on the whole foot) and maximum pressures were recorded for the more skilled or club throwers during the right foot contact at the beginning of this stride. For the left foot lauding before release, t he club throwers exhibited higher overall maximum forces and overall p ressures (the largest forces and pressures recorded on any of the diff erent foot regions) than the novices. The differences between the grou ps in the medial forefoot region contributed significantly to this res ult.
