The need to attract grants to support research efforts, has caused many sport biomechanists to change direction and commence projects in exercise rehabilitation, gait and clinical biomechanics. The opportunity to publish sports biomechanics research in international journals is also diminishing, and many university administrations do not consider "coaching journals" as representing a quality publication. We must therefore ensure that our research efforts have relevance. Three-dimensional descriptive studies are always a good start point in the analysis of movements that have not received research attention. Similarly optirnisation / simulation projects "that address a suitable hypothesis" are also important. However, two of our primary roles must be to reduce the incidence of injury through identification of "offending" movements (prospective studies) and improve athlete performance by providing coaches with an appreciation of movement techniques that assist performance. In this paper I will review the following examples of how sports biomechanics research can identify causal mechanisms to peak performance and injury reduction. 1.
