The aim of work was to determine the level of strength-speed preparation of footballers at the beginning and at the end of preparatory period, on the base of vertical jump performance. Trials were recorded with piezoelectric force platform KISTLER 9182C. No significant differences in values of jump height as well as of average and maximal power were found. It could indicate lack of significant effect of exercises, applied in training of footballers with high sport level, on the level of force-velocity preparations.

Thirty one young men volunteered to the study. After pre-testing two groups completed 4 weeks (5 days per week) of two versions of power training programs (4x10 take-offs on a inclined plane; intervals 120 or 30s.). Additional external loads to increase external power were applied. Training effects were monitored by: maximal muscle torques (measured under static conditions for the knee, hip and ankle joints) and lactate concentration in the blood. Results of the study showed no significant differences between groups in increase of the sum of muscle torques nor in lactate. Significant differences (up to 26%) were revealed in lactic acid concentration in blood between groups in post training measurements (less while exercising with long intervals).
