Effects of different exercise intensities or durations on salivary IgA secretion.

ABSTRACT:

Purpose

This study aimed to examine changes in salivary immunoglobulin A (s-IgA) secretion at different intensities or durations of acute exercise.

Methods

Twelve healthy untrained young males were included in randomized crossover trials in Experiment 1 (cycling exercise for 30 min at a work rate equivalent to 35%, 55%, and 75% maximal oxygen uptake [ V˙ O_2max]) and Experiment 2 (cycling exercise at 55% V˙ O_2max intensity for 30, 60, and 90 min). Saliva samples were collected at baseline, immediately after, and 60 min after each exercise.

Results

Experiment 1: The percentage change in the s-IgA secretion rate in the 75% V˙ O_2max trial was significantly lower than that in the 55% V˙ O_2max trial immediately after exercise (- 4
