Effects of the Applied Physical Activity to Locomotor, Metabolic, Psycho-Social and Educational Status of the Population of the Republic of Serbia (MESTD - 47015)


The aim of this paper is to determine the differences in general and specific explosive isometric muscle force in male and female cadet judo athletes. The results of the measured contractile characteristics were obtained by application of a standardized test battery using the isometric dynamometry method for the following five muscle groups: flexor muscles of the le (ŠL) and the right hand (ŠD), back (MRT) and leg extensor muscles (NOGE) and the ankle joint plantar flexor muscles (LIST). The testing included a sample of 14 participants who were competing in the system of individual national championship of the Republic of Serbia for the given age category. On the basis of the obtained results, it can be argued that a general, statistically significant, difference exists between tested judo athletes in the function of gender, both for the absolute values of the variables of basic and specific explosive isometric muscle force (Wilks' Lambda Value 0.000, F=898.61, p=0.000), as well as between the partialized (relative) values of the measured variables (Wilks' Lambda Value 0.001, F=325.71, p=0.000). e highest level of difference between male and female athletes in relation to the absolute values of the obtained results was determined for the variables of the specific explosive isometric muscle force of the le hand flexor muscles (RFDmax_ŠL, p=0.001), leg extensor muscles (RFDmax_NOGE, p=0.003) and right hand flexor muscles (RFDmax_ŠD, p=0.005). In relation to the relative values obtained by partialization of absolute values in relation to skeletal muscle mass (SMM) the highest level of difference was determined for variables of specific isometric explosive muscle force for the le and the right hand, respectively (RFDmax_ŠLSMM, p=0.000; RFDmaxŠDSMM, p=0.003). The summarized value of the gender dimorphism index (IPD) is at the level of 71.55 and 53.09% for both absolute basic (RFDFmax) and specific (RFDmax) explosive isometric muscle force, respectively. is indicates that the tested girls reached 71.55% and 53.09% of the given contractile characteristics compared to the tested boys. However, when the measured variables are partialized relative to the skeletal muscle mass (SMM), the fore mentioned differences are lowered to 101.98% and 71.58%, respectively. On general level, the obtained results have shown that there are methodological indications of scientific justication in relation to the partialization of the results of explosive isometric muscle force as a measure of development of contractile muscle potential directly responsible for the intensive manifestation of muscle force in the unit of time, in relation to skeletal muscle mass.
