The aim of this work was the determination of the cycloergometer exercises influence on the lower limbs power changes and height of rise of the body mass centre, measured in CMJ (counter movement jump) and performed on a dynamometric platform. Forty-three students of the University of Physical Education took part in the study. They were divided into 4 groups. The cycloergometer training encompassed 5 intermittent efforts parted by 2min intervals. Students performed: group M10 – maximal efforts with the load equal 10% of body mass; group M5 – maximal efforts with the load of 5% body mass; group W80 – 3min efforts with the power of 250 W, singular effort work equal 45 kJ, pedalling rate – 80 rpm; group W45 – 3min efforts with the power of 250 W, individual effort work equal 45 kJ, pedalling rate of 45 rpm. The control measurements of lower extremities power and the height of rise of the body mass centre in CMJ jumps on the dynamometric platform, were taken every Monday: before training (0), during 4 weeks of training (1-4) and for 2 weeks after it (5-6). Four week training elicited in groups M10, M5, W45 and W45 significant increase of the maximal (except group W45 where it was unimportant) and average power and, decrease of the height of the body mass centre lift in CMJ jump: crucial in groups W45 (-4.7%) and W80 (-4.7%) and not important in M10 (-3.4%). The height of rise of the body mass centre insignificant increase in group M5 (2.1%) after 4 week training. KEY WordS: cycle ergometer training, cMJ, height of jump, power output Linossier et al. [25,26,27], Parry et al. [28], Simoneau et al. [32,33] and Stathisa et al. [35] the sprint training on the cycloergometer elicited the growth of the maximal power and the amount of performed work in the Wingate test – 10 lasting for 90 s maximal efforts and calculated from F-v and P-v characteristics. On the other hand, in work of Fidelus et al. [13] the growth of muscle torque and the power loos during maximal jump on the inclined plane was noticed after 4 week speed training. Changes of lower limb power and height of rise of the body mass centre under the influence of training performed on the cycloergometer are not widely described in references. Only in few of works it is possible to find some significant dependences between the maximal power produced on the cycloergometer and lower extremities power [8,9] and the height of rise of the body mass centre measured in CMJ [38] and SJ jumps [19]. Namely, it might be expected that if the maximal power, calculated from F-v and P-v dependences, grows after the cycloergometer training (Wingate test) than the maximal power measured on the dynamometric platform also should be growing.
