ABSTRACT
Evaluating the response of the blood lactate in situations which require effort and setting the anaerobic threshold is a relatively new method, widely used in high performance sport, as well as in the research field where it is correlated with the physiological and biochemical activity of the body. The purpose of the research is to compare and correlate the results of the VO2 max and the maximal aerobic speed (MAS) with the VAMEVAL field test, and the anaerobic effort threshold found by measuring the blood lactate respectively, as well as the effect of training at different percentages of MAS (85%, 100%, 120%) on the anaerobic threshold. In carrying out this research, we started from the hypothesis that training at high percentages of MAS can lead to an increase in the capacity of aerobic and anaerobic effort. The tested subjects are twelve young football players, with ages between 16 and 18. In order to single out these correlations, we have used an experimental protocol, different for each of the three groups, consisting in training at different percentages of the maximal aerobic speed. The results have proven that training at an intensity of 100 and 120% of MAS has physiological consequences on the aerobic capacity of effort, but also on the anaerobic threshold, thus, implicitly, on the anaerobic capacity of effort. Furthermore, the results show the fact that training at 80% of MAS does not influence the anaerobic threshold.
