The purpose of that study was to determine the effect of training of one side of the body on changing the value of the muscle torques on trained and untrained sides. Twenty female students from the Warsaw University of Physical Education were subject to a four-week knee joint power training regimen on the specially designed stand. The same load but different rest time between lapses (120 vs. 30 seconds) were applied to both groups. The load was applied in a form of bending moment equal to 30% of MVC. Bilateral knee force was measured on the Biodex System 3 Pro under isometric conditions. Extension of the rest time between lapses resulted in a higher increase of the strength build-up. Power training causes a similar increase of force generating capacity in both groups for untrained leg. Therefore we have to conclude that there is no influence on homogeneous force improvement for untrained leg after power training.

The aim of this study was to determine the effects of two various types of power training on the muscle torques and power levels of lower extremities. During four weeks (five days a week) 27 students participated in this study. The training device consisted of an incline plane and a sliding seat. The varied types of power training were achieved by utilizing intermissions between the series of take offs. 4 series of 10 takes-offs with rest periods among series were carried out in A group (120s in length). Whereas the group B carried out the same number of take offs (40 take-offs) continuously. The interval training (group A) resulted in more effective dynamic values of the lower extremities than the continuous training adhered to by group B.

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).
