Effects of Exercise Stress on Parotid Gland Secretion

Abstract

Parotid secretion of alpha-amylase and potassium (K+) was determined in young adults following intense exercise. Exercise stress led to a significant elevation in alpha-amylase and K+ secretion, indicating an activation of adrenergic receptors supplying the parotid gland. Evidence of circadian variation or adaptation over days was not found.

Changes in the Salivary Biomarkers Induced by an Effort Test

“…Therefore, monitoring total protein concentration is an effi cient tool and an alternative noninvasive biochemical method for determining exercise intensity. to exercise on a treadmill [12] , running [24,33] and cycling [8,37] . Furthermore, sAA assessment has been proposed as a useful tool for evaluating psychological stress [13,25,35,36] .…”

Human salivary alpha-amylase reactivity in a psychosocial stress paradigm

“…For example, there is evidence that alpha-amylase levels increase in response to physical stressors, such as treadmill exercise (Gilman et al, 1979a), exposure to a high-pressure chamber (Gilman et al, 1979b), running (Nexo et al, 1988;Steerenberg et al, 1997), bicycle exercise (Chatterton et al, 1996;Walsh et al, 1999) or cold exposure (Chatterton et al, 1996).…”

Single-walled carbon nanotube chemoresistive label-free immunosensor for salivary stress biomarkers

“…Several investigators12,13 have demonstrated that SAA concentrations are closely associated with plasma catecholamine levels, particularly norepinephrine (NE), and are highly correlated with NE changes in response to stress. Numerous other studies14–17 have shown that SAA levels increase under a variety of physical and psychological stressors, thus suggesting that SAA may be a useful indicator for activity of the sympathetic nervous system 18…”
