Correlations between serum and salivary hormonal concentrations in response to resistance exercise

Abstract

The aim of present study was to examine the relationships between serum and salivary values of free testosterone, dehydroepiandrosterone, and cortisol before and after a session of resistance exercise. Twenty-eight healthy men (mean age 40 years, s = 4) participated in the present study. Serum and salivary samples were collected at rest and after a multiple-sets resistance exercise protocol, of approximately 25 minutes duration. Concentrations of free testosterone, dehydroepiandrosterone, and cortisol were measured using radioimmunoassay kits. No significant correlation was observed between serum free testosterone and salivary testosterone (r = 0.22 to 0.26, P > 0.05). Serum cortisol was significantly correlated with salivary cortisol before (r = 0.52, P = 0.005) and after (r = 0.62, P = 0.001) the exercise protocol. Serum and salivary concentrations of dehydroepiandrosterone were significantly correlated before (r = 0.68, P < 0.001) and after (r = 0.7, P < 0.001) exercise. The results of the present study suggest that even under exercise conditions, the salivary values of cortisol and dehydroepiandrosterone can reflect the behaviour of these hormones in blood. However, further studies are necessary to verify if salivary testosterone reflects the behaviour of serum free testosterone during resistance exercise.

Circadian variation of salivary immunoglobin A, alpha-amylase activity and mood in response to repeated double-poling sprints in hypoxia

“…Although, the levels of enzymes and antibacterial compounds are far lower in saliva than blood samples (Papacosta and Nassis 2011), these levels are closely correlated (Cadore et al 2008;Tanner et al 2014;VanBruggen et al 2011). Thus, sIgA and sAA activity can be determined frequently without interfering with the training and daily routine of the athletes (Gatti and De Palo 2011;Papacosta and Nassis 2011).…”

Relationship between salivary and serum testosterone levels in response to different exercise intensities

“…[3][4][5][6] Studies involving endurance or aerobic-based training are fewer in number and have typically studied hormonal responses to only low intensity exercise or a single bout of exercise, with mixed results. 7,8,18 If salivary hormonal assessments are to be valid and used more frequently in exercise research, it is important to establish whether such measures are reliable and comparable to blood (serum) responses across multiple intensities of exercise in a variety of activities.…”

Effects of the Menstrual Cycle and Acute Aerobic Exercise on Cytokine Levels

“…Generally, these hormones have been used as stress markers [11,25,33]. Bernstein et al [34] investigated an association between sympathetic responsiveness and the serum concentration of IL-6 in young women.…”
