Abstract

The present study examined the response of salivary immunoglobulin A (sIgA) to endurance surf lifesaving (SLS) competition. Elite SLS men (n = 10) and women (n =8) volunteered to participate in the present study. Saliva samples of 0.5 mL were collected daily commencing 54 h pre-event to 61 h post-event. Saliva samples were assessed using a portable system. Saliva samples were collected at rest and prior to physical exertion or activity at approximately 0500 hours to determine the pre-and post-competition baseline values, while the post-event sample collection occurred within 30 min of race completion for each athlete, between approximately 1300 – 1600 hours.

A significant (p < 0.05) increase in sIgA concentration was observed 61 h post-event (49.21 ± 8.8 µl/mL) in males compared to all other time-point samples. The results of the present study indicate that there is a non-significant increase in sIgA concentration for both genders immediately following an endurance SLS event, lasting approximately 90 min. The mechanism responsible for the non-significant increases in sIgA concentrations observed post-event in both genders and significant increases in sIgA concentrations observed 61 h post event in males remains unclear and may reflect an immune-compensatory effect to protect the athlete from the acquisition of infection. Surf lifesaving athletes and coaches should monitor sIgA concentrations throughout major competition periods to observe fluctuations in mucosal immunity, which may reflect a predisposition to infection, and tailor exercise and recovery prescription accordingly to minimise the risk of infection and subsequent declines in performance.
