Introduction. Aerobic training plays an important role in soccer and is designed to improve players’ cardiovascular health. Aim of Study. The aim of this study was to assess the impact of a semi-long distance outdoor run on the lipid profile of soccer players. Material and Methods. Plasma activity of lipase (LP) and blood levels of triglycerides (TG), total cholesterol (TC), lipoproteins cholesterol: HDL-C and LDL-C, were determined among sixteen (8 male and 8 female) soccer players, before, immediately after the run, and at the beginning of recovery time (30 minutes after the run). Results. The semi-long distance outdoor run caused a 30% decrease in the TG level in both studied groups (p = 0.0019 and p = 0.0002, pre-exercise vs. post-exercise for males and females, respectively). Post-exercise changes in TC (p = 0.0121 and p = 0.0158, pre-exercise vs. post-exercise for males and females, respectively) were observed. The changes in HDL-C level (p = 0.0001 pre-exercise vs. post-exercise) in males and LDL-C level (p = 0.00003 pre-exercise vs. postexercise) in female soccer players were also found. Additionally, there were no post-exercise changes in LP activity among the studied female players, however, a significant (p = 0.0119) post-exercise decrease in LP activity among the male players was found. Conclusions. Post-exercise changes in lipid profile and LP activity (at least among males) are markers of soccer players’ biochemical adaptation to the training process.

The purpose of this study was to present a time motion differences between Romanian and Polish young soccer players during 6 vs 6 small sided games. Young male football players from Schools of Sports Masters in Oradea (Romania) and Łódź (Poland) participated in the study. During the training session the players participated in four small-sided games 6 vs. 6 with goalkeepers (4 × 4 min, 3 min of active recovery). Heart rate responses and distance covered during small-sided games were compared. There were significant differences in the distance covered by both nationality players and age groups in reference to each intensity zone. Polish players coverd significantly longer distance compared with romanian soccer players. The results of motion abilities of young players from two countries with different training systems show that training programs can have a significant effect on adoptive abilities of the players.

Recently developed the agility and skill tests (AS) were reevaluated to assess the children’s agility together with the soccer shoots to ball for goal. Children (male) soccer players (N = 68) (age = 11.6 ±0.5 yrs; height = 147 ±6.6 cm; weight = 35.5 ±5.6 kg) participated in this study. Test-retest and comparisons, including 20 m Sprint, Long Jump, T-Drill Test, AS (with ball), AS (goal success) and Zigzag Tests were used to assess the children’s sprinting, jump power, and agility with shooting ball. All handled test results showed that there were significant differences between the test-retest sessions (p < 0.01) except for the 20 m Sprint. There were a near perfect correlations between test and retest values (r = 0.90–0.99). A higher level of correlation between the AS tests (goal success, with ball) (r = 0.99) was found. There were very high levels of correlations between the AS (goal success and with ball) tests and Zigzag tests (r = 0.71, r = 0.70 respectively). These results suggest that the AS tests are reliable and valid agility and skill tests for children players. Because the AS tests have unique values and are composed of soccer specific agility and active shooting skills, they are very important in identifying the talent and ability of children.
