Table 4 Basal and stimulated GH levels in response to an insulin tolerance test (ITT) in athletes (ATL) and non-physically active control subjects (NPAC)

From: Enhancement of hypothalamic-pituitary activity in male athletes: evidence of a novel hormonal mechanism of physical conditioning

Hormone ATL (n = 25) NPAC (n = 12) P-value (ATL × NPAC)
GH (μg/L) (median; 95% CI)
 Basal 0.26 (0.1–1.26) 0.06 (0.03–0.47) 0.003
 During hypoglycemia 2.50 (0.08–40.94) 0.16 (0.05–8.13) 0.006
P-value of Δ GH (x basal) 0.0002 NS  
 30 Minutes after hypoglycemia 12.73 (1.1–38.1) 4.80 (0.33–27.36) 0.015
P-value of Δ GH (x basal) <0.0001 0.0002
