Summary
Purpose: To analyze the effects of 8-week supplementation with anthocyanin compounds
contained in black chokeberry (Aronia melanocarpa) on indicators of inflammation and
oxidative stress.
Hypothesis: Supplementation with anti-inflammatory and antioxidant anthocyanin compounds
improves recovery from intense exercise by reducing inflammation and oxidative stress in
highly trained rowers
The study consisted of a nutritional intervention (supplementation) - with compounds of
natural origin - chokeberry extract (capsules) - 18% standardized for anthocyanin content
(dose 3 x 200 mg per day) - that is, 107 mg of pure anthocyanins per day, or a placebo
product that was made from chokeberry fiber
Study plan I term of the study
1. Conduct a body composition analysis, body height, food diary, self reported
gastrointestinal scale
2. Collection of blood samples before the exercise test for biochemical determinations.
3. Exercise test of 2000m on a rowing ergometer.
4. Collection of blood immediately after exercise and 1 hours after
5. Collection of blood for biochemical determinations 24 hours after the end of the
exercise test
6. Supplementation for 8 weeks 2nd test date Repeat the measurements from the 1st test
date.
Participants: Youth National Rowing Team of Poland Experimental procedure: Observation of the
effect of black chokeberry consumption on parameters of inflammation, oxidative stress and
intestinal parameters during the immediate start preparation period in highly skilled rowers.
