Influence of Somatic Factor on The Physical Efforts of Complex and Multidirectional Structure
Journal Title: Antropomotoryka. Journal of Kinesiology and Exercise Sciences - Year 2004, Vol 14, Issue 28
Abstract
Introduction. Somatic build of the body, especially the body mass, considerably influences a human motor activity. Body mass as well and its composition cause the level of muscle strength of an individual. But the greater values of muscle strength may ambiguously influence the results of individual’s motor action in dependence on the structure of this motor task. It causes some troubles in evaluation of the role of somatic factor in situation when a complex motor task is taken into account. The purpose of the work. Hence objective of the paper is to study the relationship between the structure and function in cases when considered physical effort has a complex and multidirectional character. The multidisciplines sport events are an example of such efforts.Material and methods. For the sake of amount and diversity of component events of decathlon, the sports achievements of 100 world best decathletes from 1.01.2004 rank list as well as their somatic features where analyzed. The results of shot-put where taken as a measure of absolute muscle strength of an athlete. Next they were used in construction of two types of indices of relative strength – „traditional” and „regressional” i.e. independent on the body mass. The whole sample was then divided into 3 groups of different sports skill and 4 groups of different body build. Results. Statistical calculations with use of broad correlation analysis made possible to estimate the role which play both basic somatic features and Rohrer index in sports achievements in each decathlon’s event. Diverse values of correlation coefficients in separated groups emphasize the importance of somatic factor as well as sports skill of an individual in their reciprocal relation.Conclusions. The results of analysis allow to formulate the postulate that in research of this type the analyzed sample must be selected from the high trained athletes.
