Abstract

Introduction. The relative evaluation of muscular strength is possible due to its close relation to the body build. Such evaluation is more objective because it is less dependent on somatic build of an individual. Commonly the relative strength is described by value of the absolute strength calculated for 1 kg of body mass. In weightlifting, in order to compensate a handicap connected with belonging to the different weight classes, this trait may alternatively by transformed mathematically. The indices obtain in such a manner almost entirely eliminate the influence of the body build on sports results.The purpose of the work. These two forms of evaluation of the strength ability were compared by estimation of their prognostic values in dependence on used strength measurement, mathematical construction of indices and structure of analyzed motor task.Material and methods. The groups under consideration consisted of 266 women and 390 men which were students at University of Physical Education in Wroclaw, Poland. Body mass, dynamometric measurement of hand grip, forward and backward 2 kg medicine ball throws were taken into account, as well as such sports events like 100 m run, long jump, shot put for verification of usefulness of derived indices. Apart from traditional indices the new ones were derived from absolute strength value related to the logarithmic, exponential and regressional transformation of body mass. Results. Correlation analysis showed moderate connections between traditional indices and body mass, and also utter lack of such connection with newly-derived indices, irrespective of the mathematic form of transformation of this somatic feature. Usefulness of evalutation of the absolute strength as well as its relative forms occurred to be dependent on space-temporal structure of considered sports event and kind of strength which does manifest in it. It turned out that the traditional indices were more useful for prediction the results of run and jump, while the indices of the specific strength were better for prediction the results in shot put.Conclusions. Presented indices make possible to evaluate the actual strength ability independently on body mass. In case when such requirement is not necessary one can choose and index which is mostly prognostic for certain motor task.
