The effect on 4-month judo training period on anaerobic capacity, blood lactate changes during the post Wingate test recovery, and resting plasma cortisol, and testosterone levels in male senior judokas

The best way for rating of effectiveness of training period is the examination of a post training changes in physical fitness using standardized exercise test performed on ergometer, motorized treadmill or the others equipped with system for reliable determination of biomechanical parameters. For de termination of anaerobic capacity, the most frequently utilized type of maximal bout performed by lower(legs cycling), and upper body limbs (arms cranking) are Wingate tests lasting from 10 to 30 seconds. These exertions are of high diagnostic value, and their performance are related to the other physical abilities like maximal bench press, which performance level is related to a high extent with Wingate peak power [1]. During high intensity exertion predominant source of ener gy originates from anaerobic processes, that is confirmed by rise of blood lactate level (LA). However, as has been shown, LA peak did not appeared directly after short anaerobic exertion. Studies on LA time course following judo match showed bi-phase changes (risedrop), and that dynamics within the period from +1 to +15 minutes is the best fitted by an equation of the parabola [2], but for longer recovery period (0.5h) that way of approximation is not adequate. The LA behavior in blood were recorded after various supra-maximal exertions including classic Wingate (30s) test [3-11]. An alternative to parabola approximation non-linear curves was proposed by other authors. It is bi-exponential 3or fourparameter functions describing the compartmental model
