The aims of this study were: (1) to characterize the training load structure and the applied training means in typical microcycles of the transition period and the competitive season administered to young soccer players, and (2) to present exemplary training units of the competitive and the transition periods.20 young soccer players (12-13 years old) took part in the study. Jastrzębski's method based on Sozański and Śledziewski was applied to register and monitor the training load. Data was analyzed regarding the information range (general or specific drills) as well as energetic zones (aerobic, mixed aerobic-anaerobic, anaerobic lactate or anaerobic alactate drills).The results of study show crucial differences in the applied training means in the analyzed microcycles. In a typical microcycle of the transition period general drills predominate, while during the competitive period - specific drills prevail. The total effective time of training was longer in the competitive season microcycle. It is a proper relationship according to the theory of sport training.The range of the training load registered in the competitive season is in line with other authors' research where league matches and small-sided games were used particularly often. The studied microcycles in the competitive season can be model ones and can be used in the training process of young football players.

The aim of this study was to assess lactate threshold changes during a half-year training cycle in S.S.A. "Arka Gdynia" football team.The research was conducted on a sample of 17 "Arka Gdynia" Football Club players. The subjects participated in premier league competitions in autumn 2009/10 season. Apart from league matches (17) the players took part in Remes Polish Cup (2 matches). Aerobic capacity tests were conducted at the beginning of the summer preparatory season (test 1 - 27th June 2009), during the competitive season (test 2 - 2nd September 2009) and at the beginning of the winter preparatory season (test 3 - 13th January 2010). The players underwent an incremental running test. Running speed (V/LT) and heart rate (HR/LT) at the lactate threshold were determined. An analysis of mean running speed values at LT intensity in each study confirms that during the first two tests participants achieved the same mean value of the ratio V/LT (3.80 m/s). The last test revealed a regression of the results by 0.17 m/s. The lowest standard deviation (± 0.20 m/s) was observed in the first study, which indicates that the diversity of the group was the smallest.Goalkeepers achieved statistically lower (p<0.05) values of running speed at the intensity corresponding to the anaerobic threshold (V/LT) in relation to field players.

The aim of the study was to assess the anaerobic threshold (lactate threshold LT) changes during winter and summer preparation period in soccer premier league and first division players. It was assumed that the index value varies depending on the stage of a one-year training cycle.Tests were conducted on the premier league and first division soccer players. Physical capacity tests were carried out at the beginning and at the end of the winter and summer preparation period. The tests covered 3 years: 2008 - 2010. Subjects performed an incremental running test according to Jastrzębski's method. The most important data obtained from this test are: running speed (V/LT) and heart rate (HR/LT) at LT.At the beginning of summer preparations the players' speed corresponding to LT reached the value of 3.69 m/s ± 0.31 m/s, while at the end of this period it increased to 3.86 m/s ± 0.29 m/s. During the winter preparatory season the values of this index were 3.81 m/s ± 0.3 m/s and 3.80 m/s ± 0.21 m/s, respectively.Tested subjects showed lower values of running speed at LT level at the beginning of the summer preparatory season than at its end. At the final stage of the winter preparatory season HR values at LT were significantly lower than at the initial stage of this period.
