Table 5 Basal and stimulated prolactin 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)
Prolactin (ng/mL) (median; 95% CI)
 Basal 12.1 (7.2–23.0) 10.6 (7.9–15.7) NS
 During hypoglycemia 17.8 (10.0–63.4) 12.2 (7.2–15.9) 0.01
P-value Δ Prolactin (x basal) 0.0032 NS  
 30 Minutes after hypoglycemia 24.3 (10.5–67.4) 10.5 (6.2–43.4) 0.002
P-value Δ Prolactin (x basal) <0.0001 n/s (0.98)
