Table 2 Mean (±SD) basal serum cortisol and response to insulin tolerance test (ITT)

From: Hypothalamic-Pituitary-Adrenal (HPA) Axis Functioning in Overtraining Syndrome: Findings from Endocrine and Metabolic Responses on Overtraining Syndrome (EROS)—EROS-HPA Axis

Cortisol response to ITT (μg/dL) OTS athletes (OTS)
(n = 14)
Healthy athletes (ATL)
(n = 25)
Non-active subjects (NCS) (n = 12)
Basal 11.6 (± 2.5) 12.5 (± 3.1) 10.9 (± 2.8)
During hypoglycemia 12.4* (± 3.3) 15.9& (± 5.3) 11.8 (± 3.1)
30′ after hypoglycemia 17.9*** (± 2.9) 21.7&&&& (± 3.1) 16.9 (± 4.1)
Absolute increase from basal to 30 min after hypoglycemia 6.3** (± 2.3) 9.2& (± 3.7) 5.9 (± 3.9)
  1.  Differences between OTS and ATL: *p < 0.05; **p < 0.01; ***p < 0.005
  2.  Differences between ATL and NCS: & p < 0.05; &&&& p < 0.001
  3. SD standard deviation
