Résumé

The aim of this study was to evaluate serum and saliva adrenocortical hormones and their relationships at rest and during submaximal exercise and recovery in 9 obese diabetic middle-aged men (BMI: 35.2 ± 1.6 kg / m2). Blood and saliva samples were taken at rest, every 10 min of a 30-min cycling exercise at 70 % of maximal heart rate, and after 10 min of recovery in order to analyze cortisol, dehydroepiandrosterone sulfate (DHEA-S) and dehydroepiandrosterone (DHEA). Serum and saliva cortisol increased significantly during recovery (p < 0.05), but no signifi cant difference was observed between the rest, exercise, and recovery DHEA-S and DHEA concentrations. A strong correlation was found at rest between both serum and saliva cortisol (r = 0.72, p < 0.001) and DHEA-S and DHEA (r = 0.93, p < 0.001). Serum DHEA-S and saliva DHEA remained strongly correlated during and after the submaximal exercise (r = 0.81, p < 0.001), whereas a weaker but still significant relationship was observed between serum and saliva cortisol during and after the exercise (r = 0.52, p < 0.001). In conclusion, these results suggest that saliva adrenocortical hormones, and especially saliva DHEA, may o�er a practical surrogate for serum concentrations during both rest and exercise in obese diabetic men.
