Purpose. The study aims to determine the effect of plyometric exercises performed with minimum ground contact time on the maximal power output of the legs and jumping ability. Basic procedures. This study sample comprised 44 non-training students of physical education. Following randomization, the experimental group performed plyometric exercises for six weeks, whereas the control group participated only in lectures. The subjects performed counter movement jumps (CMJ), depth jumps (DJ) and a five-hop test. Main findings. After the completion of plyometric training, an increase in the relative maximal power output (p ≤ 0.001) in CMJ and DJ was observed, whereas the center of mass elevation and the five-hop test distance length did not change significantly (p>0.05). Additionally, the rebound time in DJ was significantly shorter and the range of counter movement in the knee decreased (p ≤ 0.01). Conclusions. Depending on the aim of programme, plyometric training should determine the ways of performing exercises. Methodological guidelines in plyometric training aimed at increasing the maximal power output may be different from indications concerning jumping ability.
