Gender dimorphism of basic indicators of leg extensors F-t curve regarding top level volleyball in Serbia

The aim of this paper was to define gender dimorphism and model of basic indicators for evaluating leg extensors force-time characteristics, in top level volleyball players. Thirty-nine top level volleyball players of both genders (EliteMALE, N=19; EliteFEMALE, N=20) performed a standardized “isometric leg press” test in order to assess the characteristics of isometric force from their leg extensors. The results of all observed absolute and relative indicators for the estimation of the isometric force of the leg extensor indicate that they are beter values measured in male volleyball players at the level of Wilks Lambda 0.055, F=23.803, p=0.000. Also, it was founded that there are statistically significant differences in the examination of the contractile sub-space in relation to the subjects: FmaxLEGEXTISO F=44.251, p=0.000; FallomLEGEXTISO F=16.077, p=0.000; tFmaxLEGEXTISO F=23.731, p=0.000; RFDallomLEGEXTISO F=67.297, p=0.000; RFDBASICLEGEXTISO F=73.121, p=0.000; IndexSNGBASIC F=24.989, p=0.000. The greatest differences in the observed characteristics of the isometric F-t curve of leg extensors were measured in RFDBASICLEGEXTISO (238.88%), while the smallest differences were observed in FallomLEGEXTISO (30.98%).
