The study is primarily concerned with the analysis of cinematographic records of human movement. Computational techniques for smoothing and differentiation of numerical data are examined and a suitable method is established as a computer programme. The programme accepts displacement data from cine film of a body action and produces inertia force components of the body segments. The equation of motion is expressed in terms of a sumation of segmental forces. The computed results are compared with the total reaction measured on a force platform and arc also used to indicate the segmental contributions in the sunmation. The analytical procedures are general, but are here applied to cimp2e athletic activities. Discussion of body motion and external force action is followed by estimation of the internal effects in muscles and joints in the lower limbs. During the course of the work, discussion of segmental models of the human body and of scum mechanical principles is undertaken. These sections range beyond the requirements of the central study and offer some broader considerations in movement analysis.
