<bold>Background:</bold> The purpose of this study was to determine changes in anaerobic capacity at 100% physical effort intensity in the examined people.
<bold>Material/Methods:</bold> 12 male students from the University of Physical Education in Warsaw were subject to these examinations. The average age was 23.6 years, mean body height 178.7 cm, and body mass 80.6 kg. The experiment was carried out from 7th January to 8th March 2008. The experiment (one group) was carried out in two stages. The first stage had 25 training units on a cycloergometer within 5 weeks. The second stage was connected with controlling the obtained results for 3 consecutive weeks after completing the training. An individual load consisted of 6 efforts (10s work, 60s rest) performed with intensity at 100% of the individual's maximum power in consecutive test trials. All training and test trials were performed by means of the Monark 824E (Sweden) cycloergometer linked with a PC computer, MCE v.4.0 software.
<bold>Results:</bold> The results revealed that effort stimuli made significant changes in mechanical work, maximum power, time of achieving maximum power after a four-week period of exercises on a cycloergometer.
<bold>Conclusions:</bold> The used training loads significantly affected the improvement of the results in terms of mechanical work, maximum power, time of developing and maintaining it.
The dynamics of changes of anaerobic capacity parameters, after completing the training, may be used as a factor of reliable steering the training loads in terms of intensity.
