MENDES, E.L. et al. Carbohydrate intake results in lower suppression of salivary immunoglobulin A in judokas. Rev Andal Med Deporte [online]. 2018, vol.11, n.1, pp.36-40. ISSN 2172-5063. https://dx.doi.org/10.1016/j.ramd.2016.02.012.
Objective:
This study investigated the salivary immunoglobulin A response to carbohydrate supplementation during judo training.
Method:
Sixteen judokas were randomly assigned to one of two conditions: Carbohydrate solution and Placebo solution in a double-blind design. Saliva samples were collected at rest, immediately after the training session and 1 h after the training session.
Results:
The concentration of the salivary immunoglobulin A decreased during the training session in both conditions (p = 0.0002) as well as at 1 h after the training session in the placebo solution condition (p = 0.035). The rate of salivary flow decreased during the training session in the placebo solution condition (p = 0.04).
Conclusion:
Carbohydrate solution consumption during training session did not affect the athletes oral immunity, however, in the recovery period an upper-respiratory tract protection was observed.
