Javelin Throwing Technique: A Biomechanical Study
The purpose of this study was to analyze by correlational methods the biomechanical factors involved in achieving the maximal distance thrown in the javelin event. Six athlete from Aligarh Muslim University, Aligarh India were filmed by a two high speed Canon Legaria SF-10, 8.1 Mp cameras in a field setting with (1/2000 shutter speed and at 30-60fps). The cameras were set-up on a rigid tripod a...
متن کاملCinematographical analysis of javelin throwing techniques of decathletes.
Th purpose of this study was to analyse by correlational methods the biomechanical factors involved in achieving the maximal distance thrown in the javelin event. Twelve Swiss decathletes and two world class javelin specialists were filmed by a high speed (102 fps) 16 mm camera throwing a total of 20 trials. The co-ordinates of the resulting cyclograms were processed by a computer programme and...
متن کاملThe Role of the Internal Rotation of the Upper Arm in Javelin Throwing
We performed a kinematic and inverse dynamic study with javelin throwers in order to assess the role of the internal rotation of the upper arm in javelin throwing and then compare the findings to baseball throwing. On the one hand, the results show an equal behaviour of the angular velocity, torque and power curves compared to baseball pitching. The evaluated peak values differ on the other han...
متن کاملThe Optimal Shape of a Javelin
The problem of finding the optimal tapering of a free (non-supported) javelin is described and solved. For the optimal javelin, the lowest mode of vibration has the highest possible frequency. With this tapering inner damping will lead to the cessation of the vibration at the fastest possible rate. The javelin is modeled as a beam of uniform material. The differential equations governing the vi...
متن کاملJavelin: Parallel computing on the internet
Java ooers the basic infrastructure needed to integrate computers connected to the Internet into a seamless distributed computational resource: an infrastructure for running coarse-grained parallel applications on numerous, anonymous machines. First, we sketch such a resource's essential technical properties. Then, we present a prototype of Javelin, an infrastructure for global computing. The s...
