jumpThe squat jump (SJ) and countermovement jump (CMJ)from resting are measures of explosive strength. The SJ is an explosive, active manifestation of strength from static position (90◦leg flexion). The CMJ is also a reactive manifestation of explosive strength. In accordance with the Bosco’stest, these parameters were measured at the beginning ofthe study. Measurements were taken from resting conditions in order to evaluate maximum explosive strength performance. As can be seen in Table 2, performance in both groups was similar for T1 and no statistically significant differences were found after the training between groups or pre- and post training. As expected, the results indicatedthat both groups showed a similar level of improvement. Nodifferences in training stimuli were found for post-training results
