The aim of our study was to investigate the influence of twelve-week consumption of chokeberry extract on redox status, body composition, lipid profile and biochemical parameters in active handball players. The study included 16 handball players, aged 16-24 years (20.26±2.86 years). Every morning before training players received 30mL of liquid chokeberry extract for 12 weeks, during regular competition season. The research consisted of morphofunctional and biochemical testing, which was performed at three points (at the beginning of the study, 6 and 12 weeks after extract consumption). After the chokeberry extract treatment, we noticed significant changes in three main aspects. The 12-week supplementation with chokeberry extract decreased the levels of pro-oxidants (TBARS and nitrites) and increased catalase activity. Analyzing the dynamic of body composition showed a decrease in body fat (9.4±0.5 vs. 7.3±0.6kg), as well as its percent in a body (11.4±0.4 vs. 8.8±0.4%). On the other hand, the analysis showed an increase of high-density lipoprotein (1.3±0.3 vs. 1.6±0.2mmol/L) and hemoglobin (144.4±11.7 vs. 151.7±9.9g/L) after 6-week treatment.At the same time, a decrease in leukocytes (7.2±2.8 vs. 6.5±1.2 109/L) and an increase in red blood cells count (4.9±0.4 vs. 5.5±0.5 109/L) were noticed. Overall, these results emphatically show that the use of chokeberry extract dietary supplement induced a wide range of beneficial effects in the examined group of athletes.
