Description
Summary:This study investigated the effects of consumption of a juice blend made from whole fruits and vegetables on innate immunity, and chronic and acute inflammation in elite swimmers training three hours per day, compared to non-athletic controls. Nine male swimmers and seven controls were recruited and compared before and after a 10-day study period. Swimmers were randomized, and completed 10 days supplementation with or without 16 fl oz of the juice ingested pre- and post-workout, with a three week wash out period between supplementation periods. A single training bout at the end of the 10-day supplementation period caused a small but significant increase in plasma IL-6 (0.3 + or - 0.1 to 0.8 + or - 0.1 pg times ml with juice, and 0.5 + or - 0.1 to 0.8 + or - 0.1 pg super(.)ml with no juice) and IL-10 (but not other cytokines), with no differences between juice and non-juice conditions.
