Sažetak
Determining the extent to which various types of jumps associated with sprint performance is an essential matter of optimization the training process and success prediction in high level sport. The aim of this study was to examine the relationship of various unilateral jumps with 20 meter sprint performance. Although certain papers highlighted the great relationship between these abilities, this study brings a different perspective. The study involved 14 top young soccer players (age = 17.41 ± 0.82 years ; height = 177.62 ± 6.09 cm ; body mass 70.19 ± 5.94 kg) who have been tested for unilateral countermovement jumps (UCMJ), unilateral drop jumps (UDJ) from 15 cm, unilateral triple hop distance (UTHD) and 20 meter sprint performance. Pearson correlation coefficient (r) was used to explore the correlation between jump and sprint variables. All jump and sprint measures showed excellent within session reliability (ICC: 0.92 to 0.95). Data analysis has found that none of the nine variables of unilateral jumping significantly correlated with 20 meter sprint performance. The result of the UCMJ for non - dominant leg showed the highest correlation (r = -0.531), while the variable of asymmetry for UTHD indicated the lowest correlation (r = -0.009) with 20 metre sprint performance. All variables that are not based on asymmetry, negatively correlated with the score on 20 metre sprint. This substantiates previous research that better vertical jump ability is predictor of better results in sprint performance. Although the higher values of correlation coefficients were expected, these data are not too surprising considering that the population of elite young soccer players are extremely homogeneous with slight differences in performance. Ignoring the distinction of results obtained between amateurs and top athletes can lead to the wrong conclusions, which will not have the appropriate practical application.
