The vestibular acute stress induces reversible alert-like reactions that involve the sympathetic adrenal-medullar system and hypothalamic-pituitary-adrenal axis responses. The present study aimed to evaluate salivary alpha-amylase and salivary cortisol production in relation with cardiovascular reactivity induced by acute stress in healthy subjects | OBSTRUCTIVE SLEEP-APNEA | PSYCHOLOGICAL STRESS | STIMULATION | various times after reaching the maximal nystagmic reaction following air caloric vestibular test. Heart rate systolic blood pressure diastolic blood pressure and mean arterial pressure were recorded at the same time as measurement of the salivary alpha-amylase and salivary cortisol. At the end of the caloric vestibular test session | and the difference was significant ( t =-3.283; p<0.001) an increase in salivary cortisol production corresponded with a decrease in the salivary a-amylase concentration. In addition salivary biomarker modifications were associated with consistent changes in the heart rate systolic blood pressure and mean arterial pressure | DHEA-S | MULTIDISCIPLINARY SCIENCES | STRESS-INDUCED CHANGES | Following caloric vestibular test-evoked vertigo salivary alpha-amylase and cortisol showed distinct trends in their production after acute stress: Student's t-test was used to compare the alpha-amylase vs cortisol slopes of the respective interpolated regression lines | Conclusions | SALIVARY ALPHA-AMYLASE | perceived stress scale questionnaires were administered to measure the self-perceived stress impact induced by the task and individual scores were compared with those measured on the enrollment day | CARDIOVASCULAR CONTROL | EXERCISE | Material and methods | connection between the acute hormonal stress response to vestibular stimulation and cardiovascular output. However further research is needed before we can define the potential importance of the consistent cardiovascular activity changes evoked by vestibular stimulation and the possible functional consequences for cardiovascular regulation and orthostatic tolerance in humans | Using the air caloric vestibular test task as a stressor the present study demonstrated a | Introduction | Results | ADRENERGIC ACTIVITY | Forty-eight young healthy male volunteers were examined under basal conditions and at | CORTISOL | Otolaryngology | Stimulation | Systematic review | Thyroid gland | Sleep apnea | Hypothalamus | Hormones | Hydrocortisone | Blood | Vertigo | Exercise | Population | Physiology | Blood pressure | Bioindicators | Vestibular system | Stress response | Stresses | Hypothalamic-pituitary-adrenal axis | Pharmacology | Stress | Heart rate | Medicine | Physical fitness | Amylases | Pituitary | Pharmacy | Biomarkers | Orthostatic tolerance
