Background and Study Aim: Exercise testing is a gold standard in physiological assessment of an athletes. Previous research showed that in match physiology may play decisive role in wrestling. However there is no relation between results obtained in laboratory testing and real in match physiology. The objective of the present study was knowledge about the relationship of physiological variables measured during a laboratory exercise testing as a set of predictors of lactate levels during a wrestling match.
Material and Methods: Twelve elite level wrestles, completed a treadmill VO2max exercise testing and simulated match. Blood lactates were measured before each bout and at the end of the simulated match. Using stepwise multiple regression the best set of predictors were obtained for each lactate measurement.
Results: The result indicated that the strongest predictor for lactate after all three bouts was VO2max (β = -1.05, -0.81, -0.83, respectively). Respiratory frequency (Rf) had an increasing effect on lactates (β = 0.40, 0.91, 0.83) where effect of tidal volume (Tv) presented only in second and third bout (β = 0.65, 0.44 respectively).
Conclusions: The VO2max, maximal respiratory frequency and tidal volume are key indicator in physiology and lactate dynamics of a wrestling match thus our findings change physiological approach to interpretation of exercise testing in wrestlers and its utilization in wrestling and similar anaerobic sports.
