The long jump example on pages 62–71 will have shown you that deterministic modelling is not a quick fix for identifying critical features of a sports movement for qualitative analysis, even when the objective performance criterion is easily identified.However, although it takes some time to complete, it is not too difficult once you have practised it well and if you are very familiar with the sports movement involved.
The same is true for quantitative analysts using hierarchical modelling to identify the important performance variables to be measured. When the performance variable is subjective, as in all sports in which subjective judging determines the outcome score (e.g. gymnastics, diving and figure skating), an obvious alternative is to base the critical features on the judging guidelines for the particular sport. These should largely have been developed from movement principles applicable to movements within that sport, so this approach has much to recommend it, particularly for inexperienced movement
analysts.
