ABSTRACT
AIM:
The present study aimed at investigating the effect of a 3-week training on biomarkers in professional soccer players during the preseason preparation-period.METHODS:
Eight participants (age 22.5±2.2 yrs) were enrolled in the study. During the physical preparation period players have attended a training program (51.9 hours) formulated by coaches of "Equipe-Sicilia-2009".RESULTS:
At rest, the lipid profile, the creatine kinase (CK), the lactic-acid dehydrogenase (LDH) and the expression of nuclear receptors peroxisome-proliferator-activated receptors (PPAR α/γ) were analyzed before starting and after 3 weeks of training. The plasma level of CK in our samples showed great variability already in the baseline value was on average nearly 500 IU/l showed that a large amount of these athletes were a high responders. This biomarker showed a reduction (P<0.01) after 3 weeks of training. No modifications were found in the LDH plasma level, in the lipid profile and in the expression of mRNA of PPAR α/γ and also no significant person's correlations were found among variables.CONCLUSION:
In conclusion, we retain that those basal biomarkers, except CK, are not able to assist coaches to better understand training adaptations and overreaching mechanisms during a 3-week of preseason preparation-period. More studies are necessary to confirm these results.
