The researchers measured heart rate variability while the volunteers engaged in controlled breathing (12 breaths/min for 1 minute), rested in a tilted, 70-degree head-up position (4 minutes), and engaged in a cold pressor test (CPT) during which a lower arm was immersed in ice-cold water (2 minutes): "Controlled breathing stimulates parasympathetic nerve activity, whereas tilting and CPT stimulate sympathetic nerve activity." Additional tests included oral glucose tolerance test, low-dose tetracosactin stimulation test, corticotropin releasing hormone stimulation test, oral dexamethasone suppression test, and diurnal salivary and urinary Cortisol testing as well as anthropometric measures.
