Abstract

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. Verf.-Referat
