What are the chronic changes in the acute hormonal response to anaerobic training?

• A. Growth hormone
• B. Testosterone
• C. Cortisol
• D. IGF-I

Answer: (A)

Growth hormone shows the most consistent chronic change in the acute hormonal response to anaerobic training: after weeks to months of training, the surge in GH that occurs in response to a high‑intensity workout tends to become smaller. This attenuation happens because the body becomes more efficient at handling the stress of the workout, requiring less GH signaling to drive adaptation, and it may reflect changes in signaling sensitivity. The acute rises in testosterone and cortisol can still occur with a bout, and IGF‑I is largely driven by GH and muscle signaling, so the clearest, most reliable chronic change seen with repeated anaerobic loading is the blunted growth hormone response.
