Background: The purpose of this study was to determine changes in anaerobic capacity at 100% physical effort intensity in the examined people.Material/Methods: 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.Results: 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.Conclusions: 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.
Background: Physiological studies conducted for over 20 years on basketball players have shown an increasing share of anaerobic efforts during the game. The players' throw effectiveness and their ability to move quickly on the playing field often determine the result of the match. The current control of kinematics and biochemical variables is crucial in the modern training process.Material/Methods: The study was conducted on an 11-person group of male athletes from a Polish first-league basketball team. The subjects had to perform a fitness test proposed by the authors: 8×32.8m with bouncing, throwing a ball to the basket and running back without the ball. The course of the test was video-recorded. The blood sample was taken in the 1st, 3rd, 13th and 23rd minute after the test. The level of lactic acid as well as glucose concentration was assessed by Lactate Scout and FreeStyle Lite apparatus.Results: The study revealed individual differences in the level of special fitness among the players. The throw effectiveness varied from 37 to 75% (mean 59%), while the maximal lactic acid concentration varied from 6.3 to 8.5 mmol/l (mean 7.2 mmol/l). The average maximal glucose concentration was 124.6 mg/dl. The range of lactic acid restitution time differentiated the players from 21 to 55 minutes (mean 30min).Conclusions: Application of the test in practice allows determining the basic values of kinematic techniques of basketball players in terms of biochemical changes. It should be an effective tool to control and optimize the basketball training process.
