Abstract
The study analyzed the oral immunity after rugby training in athletes undergoing diet high in carbohydrates (DATC). In a randomized, double-blind, placebo-controlled, 20 athletes consumed DATC for three days before the experiment. The athletes were randomly carbohydrate drink (CHO) or placebo (PLA) and participated in two training sessions of rugby, separated by seven days. Saliva samples were taken before (Pre-E), immediately after (Post-E) and 1 h after (1 h post-E) training. Significant difference in rate of s-IgA secretion to PLA only at time 1 h post-E. DATC, days before training rugby, preserves immune function independent of oral CHO supplementation during training.
