Recently I came across an article which recommends no sugar for 2 hours after training to maximize the benefits of exercise-induced growth hormone. Until then I had believed the ingestion of simple carbohydrates right after intensive exercise was very recommendable to replenish the energy lost and avoid the breakdown of muscle tissue.
Human growth hormone (hGH) is secreted in a pulsatile fashion, generally following a circadian rhythm. A number of physiological stimuli can initiate hGH secretion, the most powerful, non-pharmacological of which are sleep and exercise. The exercise-induced growth hormone response (EIGR) is well recognized but the exact mechanism is unclear. Evidence and studies confirm that short bursts of resistance training (10 minutes) results in the best EIGR. Inadequate hydration, either during exercise or following exercise, can blunt the EIGR but I could not find any scientific articles that recommended avoiding sugar after exercise. Your statement that consuming simple carbohydrates after intensive exercise is recommended is correct. The studies have shown that endurance training does not produce a high EIGR. Therefore, I would continue to replace carbohydrates after intensive exercise and not wait.
