The effect of polyphenol-rich chokeberry juice consumption on plasma phospholipid fatty acid profiles of 32 active male and female handball players was examined. This randomized, double-blind, placebo-controlled study was conducted during the preparatory training in a closed campus, where 18 players (8 males, 10 females) consumed 100 mL of chokeberry juice, while 14 players (7 males, 7 females) consumed placebo. Lipid status, glucose, thiobarbituric acid reactive substances (TBARS), and percentages of fatty acids were assessed at baseline and at the end of the study. Consumption of chokeberry juice induced decreases of C18:1n-9 and C18:3n-3 in men, but no changes in female players. However, placebo-controlled groups had reduced proportions of mono-(C16:1n-7, C18:1n-7) and polyunsaturated fatty acids (PUFAs:C18:3n-3, C20:5n-3, and C22:4n-6) in males, as well as n-6 PUFAs and total PUFAs in females after consumption. These results indicate that chokeberry juice had a weak impact on attenuating the effect of intensive training in active handball players.
