- Abstract
The objective of this study was to clarify whether there are sex‐specific differences in salivary α‐amylase and immunoglobulin A responses following acute endurance exercise in adolescent males and females with equivalent cardiorespiratory fitness levels. Twenty‐six aerobically trained adolescent males and females with similar training status were enrolled in this study. Each individual executed a 1‐h prolonged cycling exercise corresponding to a constant power output at 65% of peak oxygen uptake. Unstimulated whole salivary samples were taken with the passive drooling method at the 10‐min period before and after exercise for the determination of salivary responses [α‐amylase, immunoglobulin A, total protein and flow rate]. Salivary α‐amylase activity, immunoglobulin A concentration and total protein concentration were significantly augmented immediately after acute endurance exercise. Regarding sex differences, only the salivary flow rate was significantly lower in females than in males. The findings of the present study imply that adolescent males and females appear to have similar salivary responses after acute endurance exercise, as represented by salivary α‐amylase activity and immunoglobulin A concentration in connection with total protein concentration and salivary flow rate, when they are matched for peak oxygen uptake relative to fat‐free body mass.
