THE ROLE OF DIET AND PHYSICAL EXERCISE Acute exercise increases GH secretion, the earlier it is, the greater its intensity. The peak response of this hormone to exercise is observed between the 25th and 60th minutes during endurance activities (running, cycling, cross-country skiing, etc.) or between the end of the 5th and the 15th minute of the recovery period, for exercises lasting less than 20 minutes
