Anaerobic capacities and blood lactate responses to wingate tests in male greco-roman wrestlers

Wingate tests are the most frequently exercise tests used to evaluate their anaerobic capacity in relation to the metabolic changes, sexes, tested extremities and training status. Short tests durations (10-30 sec), pre test warm-up and loud verbal encouragement from a researcher ensure, that examined individuals do not use pacing strategy but engage their maximal physical abilities from the start to the end of the effort. An advanced technology of power measurements online with very high frequency (1000 Hz) allow to explore various internal and external circumstances affecting levels of the performance parameters, like power output, work output and accumulating fatigue during the test, that expresses itself as decrease of the power, especially at the end of an exertion. Peak power (PP) recorded during Wingate tests showed diag nostic value for predicting of strength, power levels and performances of other exertions. Changes in PP levels induced by period of strength and power ballistic exercises were related to performance of the other tests like high jumps and shot put throws [1]. It was found, that PP during bench throw ex plained 87% and 72% of the variances in arm crank Wingate peak power in men and woman respectively [2]. Another variable recorded during Wingate, which diagnostic value seems to be not appreciated is a time to PP attain (TA). When starting an anaerobic exercise test , an examined individual has to overcome not only braking force bat also wheel inertia, thus, maximal rate of revolutions he/she usually achieves at 2-4 seconds after the start. Obviously, the higher rate of force development, the shorter the TA, and this relationship ex plains, why rate of force development (so called explosive strength) affects performance of the various athletic exertions for in stance a high jump [3]. As the completing of the Wingate test engages anaerobic sources of energy, we may observe high rise of lactate level in blood after termination of that type of effort. Generally, the higher the LA the more intensive the effort. The main issue of the study on a post effort acidosis is to find the time point, when LA reaches its peak. The behaviours of LA responses to short-lasting anaerobic efforts have been often studied in athletes. It was shown that immediately after a judo struggle lasting from 2 to 5 minutes LA peak appears at the time from
