The influences of chokeberry extract supplementation on redox status and body composition in handball players during competition phase

Abstract

<jats:p> 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. </jats:p>

Effects of antioxidant supplementation on oxidative stress balance in young footballers- a randomized double-blind trial

“…Some beneficial changes, namely, a reduction of TBARS level, and increase in haemoglobin content, erythrocyte counts, and high-density lipoprotein (HDL) levels, were reported after 6 weeks of supplementation. However, the composition of the supplement and its antioxidant potential were not described in that study [47]. Intriguingly, García-Flores et al [48] tested a combination of chokeberry extract with citrus juice (200 ml of drink containing 95% fresh citrus juice and 5% chokeberry extract) in triathlon riders.…”

“…The supplementation resulted in small changes in the lipid profile and in reduced TBARS levels in blood; however, these changes were observed only in men. By contrast, Cikiriz et al [ 47 ] tested the effects of 12-week chockeberry extract supplementation (30 ml/d) in another group of handball players. Before the supplementation, and after 6 and 12 weeks, the subjects performed maximal physical exercise on a treadmill.…”

“…After the completed period of supplementation, it was demonstrated small changes in the lipid pro le and reduced TBARS levels; however, these changes were observed only in men. Cikiriz et al [42] used aronia extract in the amount of 30 ml / day in a group of handball players. The study protocol does not provide information on the detailed composition of the supplement or its antioxidant potential.…”
