title="Original paperCHANGES IN THE ANAEROBIC THRESHOLD 
IN AN ANNUAL CYCLE OF SPORT TRAINING 
OF YOUNG SOCCER PLAYERS",
abstract="The aim of the study was to assess changes in the anaerobic threshold of young soccer players in  an annual training cycle. A group of highly trained 15-18 year old players of KKS Lech Poznań were tested. The  tests included an annual training macrocycle, and its individual stages resulted from the time structure of the  sports training. In order to assess the level of exercise capacities of the players, a field exercise test of increasing  intensity was carried out on a soccer pitch. The test made it possible to determine the 4 millimolar lactate  threshold (T LA 4 mmol · l-1) on the basis of the lactate concentration in blood [LA], to establish the threshold  running speed and the threshold heart rate [HR]. The threshold running speed at the level of the 4 millimolar  lactate threshold was established using the two-point form of the equation of a straight line. The obtained  indicators of the threshold running speed allowed for precise establishment of effort intensity used in individual  training in developing aerobic endurance. In order to test the significance of differences in mean values between  four dates of tests, a non-parametric Friedman ANOVA test was used. The significance of differences between  consecutive dates of tests was determined using a post-hoc Friedman ANOVA test. The tests showed significant  differences in values of selected indicators determined at the anaerobic threshold in various stages of an annual  training cycle of young soccer players. The most beneficial changes in terms of the threshold running speed  were noted on the fourth date of tests, when the participants had the highest values of 4.01 m · s-1 for older  juniors, and 3.80 m · s-1 for younger juniors. This may be indicative of effective application of an individualized  programme of training loads and of good preparation of teams for competition in terms of players’ aerobic  endurance.",
