Table 6 Differences of the magnitude of the hormonal responses between healthy athletes and non athletes

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) Difference between the responses of ATL and NPAC (P-value)
Cortisol change during ITT (μg/dL) 9.2 ± 3.7 6.0 ± 3.9 + 53.3% (p = 0.026)
P-value (overall increase) <0.0001 0.001
ACTH change during ITT (pg/mL) 45.1 (22.1–195.7) 38.0 (0.5–108.8) + 18.6% (p = ns)
P-value (overall increase) <0.0001 0.0065
GH change during ITT (μg/L) 12.57 (1.01–37.7) 4.74 (0.3–27.28) + 265.2% (p = 0.016)
P-value (overall increase) <0.0001 0.0004
Prolactin change during ITT (ng/mL) + 13.1 (−5.3 − + 54.5) −1.2 (−4.8 − + 30.5) n/a (only ATL responded) (p = 0.01)
P-value (overall increase) 0.0001 n/s (0.88)
