Table 6: Mean values for all variables measured in adolescent and adult female soccer players. study, for vertical and horizontal jump tests, was much higher (two to three times higher) than the findings of other studies [28; 29; 46] with adult female soccer players. Furthermore, in our study, we did not find a statistically significant correlation of asymmetries from vertical and horizontal jump test with time in linear and change-of-direction speed in adolescent female soccer players (Table 1). In a previous study [30] with adolescent female soccer players, asymmetries from vertical and horizontal jump tests did not show statistically significant correlations with linear and change-of-direction speed times. This observation is in agreement with the findings of the present study. In contrast, in another study [15] with prepubescent female soccer players, greater asymmetries from the SLCMJ test increased speed times over distances of 5 m to 20 m, while no correlation was observed between asymmetries from horizontal jump tests and speed times. It is worth noting that, although the level of asymmetries in the SLCMJ is almost the same (11-12%) for the present study and the two previous studies reported [15; 30], these asymmetries seem to reduce speed performance in only prepubescent female soccer players [15]. This fact, this may be explained by the different levels of maturity, training ages and competitive levels of the adolescent female soccer players who participated in our study and those who participated in the study by [PERSON] et al. [30]. Moreover, a significant correlation was noted between asymmetry in the SLCMJ test and asymmetry in the SLDJ test, whereas correlations in asymmetry between vertical and horizontal jump tests were absent (Table 3). These findings are in accordance with both studies noted previously [15; 30], as no significant correlation was observed between asymmetry in vertical and horizontal jumps, whereas a significant correlation between asymmetries in two types of horizontal jump tests was found [15]. Thus, it seems that asymmetries in jump tests performed in the same direction may show correlations, in contrast to jump tests performed in different directions, in which significant correlations may be absent. According to the results of our study, adult female soccer players showed a significant positive correlation (r = 0.68, \(p\) < 0.05) of asymmetry in SLH test for distance with the time in change-of-direction speed on the right leg.
