The aim of this study is to compare selected parameters characterising the level of explosive force in two age categories of volleyball players, youth boys and juniors, during two different types of jumps – standing block jump and spike jump. Eleven youth boys and ten juniors were tested. Force plate was used for the research. The average vertical ground reaction (Favg) as well as the value of the peak force (Fpeak) was evaluated. Absolute and relative values of ground reaction were evaluated. Moreover, two motor tests were carried out - standing block jump and spike jump. Junior players achieved better results than youth boys in nearly all types of take-off. During standing block jump, youth boys achieved for Favg and Fmax 2.51 and 3.22 times the body weight respectively (nBW) and juniors 2.48 and 3.35 nBW respectively. During running block jump, youth boys achieved 2.76 and 3.93 nBW respectively and juniors 2.89 and 4.17 nBW respectively. During the spike jump, youth boys achieved 2.69 and 3.76 nBW respectively and juniors 3.00 and 4.52 nBW. The both groups achieved better results for spike jump. We found out moderate correlations between VGRF and the height of jumps. VGRF differences between groups were not statistically significant for both block jumps. However, they were significant for the spike jump. This does not clearly prove higher quality of elder players in the level of explosive force of their lower limbs.
