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.
