Muscle Strength - Relative and Specific (methodological indications)
Journal Title: Antropomotoryka. Journal of Kinesiology and Exercise Sciences - Year 2004, Vol 14, Issue 27
Abstract
The purpose of the work and material. Challing and Viru introduced in 1981 the concept of specific strength as a ration of muscle strength to lean body mass. But this concept can be hardly considered as being adequate to its meaning because, like the traditional index which describes a strength in relation to body mass, it neglects the relationship between the motor ability and somatic factor. In order to verify this opinion the research was done on the sample of 367 women and 287 men. The body mass, free fat body mass and derivative indices were taken into account. Methods. From 6 trials used for estimation of motor fitness of individuals under study the 3 were chosen which indirectly determine the muscle strength and then the traditional indices of relative strength were calculated in which the free-fat body mass instead of the total body mass was used. In these new indices the values of both somatic traits mentioned above were recalculated according to established rules of score transformations applied in the weight lifting. Then some indices which significantly correlate with somatic traits were eliminated. Conclusions. The diagnostic value of indices was evaluated on the basis of their correlations with the remaining 3 tests of motor fitness. In conclusion the more adequate concept than one by Challing and Viru was proposed, namely the actual strength fitness.
