What are the most effective Biomechanics for a Volleyball Spike? Biomechanics is the study of examining forces acting on the body, and the effects of these forces. Athletes can be analysed by labratory testing under controlled conditions, field testing, or competition analysis. Biomechanics is used to diagnose an athletes weakness or better their ability. It is important to prevent injuries as well as enhance performance. In Australia, there is roughly 225,000 people playing volleyball.
