In order to study if a higher concentration of ubiquinol in blood would help the performance of players,we design a protocol to supply a blind selection of players with 300 mg ubiquinol/day (Kaneka Ubiquinol) and different extractions to study the evolution of blood content: 1) pre- season starting, final of the training pre-seasonal period, mid-season and final-season. Levels of ubiquinol in plasma after the pre-season was decreased relative to the basal content after vacations indicating that endurance exercise induced a decrease in blood as it was previously demonstrated in healthy young people .
The middle and final season extractions demonstrated that some of players were taken ubiquinol because these ones showed a significant increase independent of the exercise endurance preventing the decrease previously observed. The analysis of plasma demonstrated that cholesterol and triglycerides were unaffected during all the study and we observed a light increase of lipoperoxides as it was previously observed in a non-professional young players short-term study , but changes do not correlate with ubiquinol levels of players activities. We also analyzed creatine kinase (CK) as a marker of skeletal muscle damage and found that there was a negative correlation between the levels of both ubiquinol and CK in the player’s plasma of the third extraction indicating that ubiquinol would protect skeletal muscle cells from the extreme exercise caused by both daily training and weekly game.
