ABSTRACT
In Chapter 1 we covered the theoretical background to the mechanics of the human body. We saw how relatively simple mechanical models can be used to develop an insight into human performance. In this chapter we look at some of the problems involved in actually making in vivo measurements of forces and movements. The human body is a very complex structure and this, combined with the problems of gaining access to specific parts of the structure, can make it very difficult to make reproducible and meaningful measurements. This chapter should only be seen as the introduction to a very complex area of physiological measurement. These are some of the questions we will address:
