Rate of Fatigue of Explosive Force of Lower Extremities of Artistic Gymnasts

Rate of Fatigue of Explosive Force of Lower Extremities of Artistic Gymnasts SummaryThe aim of our work was to find out the level of explosive force of lower extremities and the rate of muscular fatigue of lower extremities of artistic female gymnasts. The research file consisted of 8 female competitors of B category (year of birth: 2010.5 ± 1.20, physical height 148 ± 10 cm, body weight 36.25 ± 5.44 kg, BMI 16,46 ± 0,68 kg/m2). In our ex post facto research, which took place in gymnastic club PAVLO Trencin, we used measuring device FiTRO Jumper that has been placed on floor exercise. In input and output measurement we found out the parameters of jumps by two standardized tests. The female probands had 2 attempts (IO: 2´) in each motoric test we recorded the better attempt on the tables. We measured the height of upward leap (V.V.) [cm] in vertical jump with countermovement (VVsPP) without swing work of arms. In 10s test of repeated upward leaps without the aid of arms we measured power in active phase of take-off (Pmax) in [W.kg−1] and fatigue index (I.U.) in [%]. Among measurements the female gymnasts underwent the circular training with 10 exercises (IZ: 40 s, IO: 15 s) and acrobatic preparation. For processing of results we used non-parametric Wilcoxon´s T-test and paired T-test in which we found up significance at the level p ≤ 0.01, p ≤ 0.05 and p ≤ 0.10 of statistical significance level. By comparison of obtained results at the beginning of training unit (TJ) in tests of VVsPP (V.V.= 26 ± 2.12 cm), 10s test of repeated upward leaps (Pmax= 40.64 ± 7.6 W.kg−1, I.U.= 23.79 ± 8.01 %) and at the end of TJ in tests of VVsPP (V.V.= 24.08 ± 1.36 cm), of 10 s test of repeated upward leaps (Pmax= 40.71 ± 5.16 W.kg−1, I.U.= 29.46 ± 10.2 %) we found out that the statistical significance was confirmed at the 0.05 % level of statistical significance only in the height of upward jump in VVsPP where significantly lower values were measured at the end of the training unit.

Abstract

SummaryThe aim of our work was to find out the level of explosive force of lower extremities and the rate of muscular fatigue of lower extremities of artistic female gymnasts. The research file consisted of 8 female competitors of B category (year of birth: 2010.5 ± 1.20, physical height 148 ± 10 cm, body weight 36.25 ± 5.44 kg, BMI 16,46 ± 0,68 kg/m2). In our ex post facto research, which took place in gymnastic club PAVLO Trencin, we used measuring device FiTRO Jumper that has been placed on floor exercise. In input and output measurement we found out the parameters of jumps by two standardized tests. The female probands had 2 attempts (IO: 2´) in each motoric test we recorded the better attempt on the tables. We measured the height of upward leap (V.V.) [cm] in vertical jump with countermovement (VVsPP) without swing work of arms. In 10s test of repeated upward leaps without the aid of arms we measured power in active phase of take-off (Pmax) in [W.kg−1] and fatigue index (I.U.) in [%]. Among measurements the female gymnasts underwent the circular training with 10 exercises (IZ: 40 s, IO: 15 s) and acrobatic preparation. For processing of results we used non-parametric Wilcoxon´s T-test and paired T-test in which we found up significance at the level p ≤ 0.01, p ≤ 0.05 and p ≤ 0.10 of statistical significance level. By comparison of obtained results at the beginning of training unit (TJ) in tests of VVsPP (V.V.= 26 ± 2.12 cm), 10s test of repeated upward leaps (Pmax= 40.64 ± 7.6 W.kg−1, I.U.= 23.79 ± 8.01 %) and at the end of TJ in tests of VVsPP (V.V.= 24.08 ± 1.36 cm), of 10 s test of repeated upward leaps (Pmax= 40.71 ± 5.16 W.kg−1, I.U.= 29.46 ± 10.2 %) we found out that the statistical significance was confirmed at the 0.05 % level of statistical significance only in the height of upward jump in VVsPP where significantly lower values were measured at the end of the training unit. Differences in parameters performance and fatigue index did not manifest themselves at the level of statistical significance.
