Structural analysis of basic leg extensor isometric f-t curve characteristics in male athletes in different sports measured in standing position
Апстракт
The aim of this study is to examine basic leg extensor isometric F-t curve characteristics obtained by testing in standing position. The sample consisted of 5 different sub-samples: power lifters (N=22), karate athletes (N=9), judokas (N=10), well trained athletes (N=39), and a control group (N=31). Six contractile characteristics were investigated: FmaxIZO-the level of maximal isometric force; tFmaxIZO-the time necessary for achieving maximal isometric force; RFDFmaxIZO-an index of basic isometric explosive force i.e. the isometric rate of force developement; FrelIZO-the relative value of the achieved maximal force; RFDFrelIZO-the relative value of isometric rate of force developement; and RFD/Fmax-an index which determines the level of development of basic isometric explosive force from the aspect of biological potential. Regarding all individual contractile parametres, the results showed that there is a statistically significant differences (p lt 0.001) between the sub-samples. Re...garding all standardized differences, where the criterion represented the result of control group, FmaxIZO in power lifters is 65.34%, in karate athletes is 11.41%, in judokas 22.58%, and at well trained population 15.12% bigger. Regarding RFDFmaxIZO in power lifters, the obtained value was 243.80%, in karate athletes 118.36%, in judokas 129.17% and in the well-trained group was 43.33% higher that the control group. From the point of view of RFD/Fmax value, the obtained value in power lifters was 243.80%, in karate athletes 118.36%, in judokas 129.17% and in the well-trained group was 43.33% higher than the control group. According to the obtained analyses here related to F-t curve leg extensor characteristics, it is possible to define initial model indicators for six tested contractile characteristics in tested athletes and well-trained populations.
