Abstract

New possibilities for characterizing and discussing variability are obtained by means of nonlinear techniques of time series. Calculation of the fractal dimension allows determination of a measure of the degree of freedom. This fact is demonstrated using the example of standing balance. When the conditions are difficult the fractal dimension decreases. Another fact we discovered in a study of the breaststroke: When the load is increased the efficiency of the movement and the fractal dimension are also reduced.
