Hpe Biomechanics

Introduction

Biomechanics is the sport science field that applies the laws of mechanics and physics to human performance, in order to achieve a better understanding of performance in athletic events through modelling, simulation and measurement. (©1997 - 2010 Topend Sports Network)
It’s very also essential to have a good understanding of the application of physics to sport, as physical principles such as motion, resistance, momentum and friction play a part in most sporting events.
The main role of biomechanics is to recognize the mechanical cause or effects that establish the motions of living organisms. In relation to sport, biomechanics contributes to the description, explanation, and prediction of the mechanical aspects of human exercise, sport and play. (Sports network 2010)

This assignment will outline the important parts of biomechanics, such as balance and stability, generating force and momentum, summation of forces and projectile motion in relation to javelin. My task will be to analyse and evaluate my javelin throw, and then identify and comment upon my technique and determine a way I could improve my javelin throw and my technique.

Balance and stability

Balance is the ability to control equilibrium while stability is the resistance to disturbance of equilibrium. For any sport, the best possible method to improve balance and stability is to practice the skill itself on the same surface on which the skill will be performed through competition. Willardson JM (2004).

Seeing that my technique in the javelin video wasn’t at its greatest, I have been able to analyse my strengths as well as my weaknesses. Besides the video, I have been working on my throwing in class and I was capable on improving my technique. Now not only do I throw further, but I also take a bigger run up and release the javelin at a higher angle of release. My major weakness is my arm which remains bend prior to the release of the javelin. Moreover I don’t shift my weight...
