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 aim of this study has been to determine the effects of hypertension on plasma lipid profile and the serum level of antioxidant vitamins in tobacco smokers. The study population comprised 62 smokers of whom 35 had hypertension (study group) and 27 were normotensive (control group). The levels of plasma lipids, albumins, uric acid, thiobarbituric acid reacting substances (TBARS) and vitamins A, E, C and ß-carotene were assayed. Cumulated index of antioxidant vitamins (CIAVIT) was also calculated. Total cholesterol (TC) (pO.OOl), LDL cholesterol (pO.OOl), uric acid (p<0.05), TBARS (p<0.05) and triglycerides levels were higher in hypertensive smokers compared to the control group. Hypertensive smokers also had lower HDL cholesterol and vitamin E levels (pO.Ol), as well as the levels of vitamins A, C and ß-carotene and the CIAVIT value. The study group exhibited negative correlation between TBARS and vitamins E levels (r=-0.46) and C (r=-0.33), and between TBARS and CIAVIT values (r=-0.34). The study results indicate that tobacco smoking exacerbates pre-existing lipid profile and antioxidant status abnormalities in hypertensive subjects.
