It has been suggested that ghrelin may play a role in growth hormone (GH) secretion to exercise.
The present study was designed to examine the effects of a single bout of circuit resistance exercise on plasma glucose, ghrelin, GH, and c-peptide, and cortisol.
Fourteen volunteer male physical education students completed a single bout circuit resistance training (10 exercises, three circuits, and at 60% of 1-RM). Blood samples were collected before, immediately after the exercise, and 24-h following the exercise protocol.
GH, glucose, and c-peptide showed a significant increase immediately after exercise and returned to pre exercise values over time. Plasma ghrelin showed a significant decrease immediately after the exercise and increased significantly 24-h following the exercise.
In conclusion, a decrease in plasma ghrelin following a single bout of circuit resistance exercise indicates that an increase in GH is not related to plasma ghrelin levels. An acute exercise-induced hyperphagia during the long-recovery was considered.
有人提出，胃饥饿素可能在运动时生长激素（GH）分泌中发挥作用。
本研究旨在探讨单次循环抗阻运动对血浆葡萄糖、胃饥饿素、生长激素、C肽和皮质醇的影响。
14名男性体育专业学生志愿者完成了单次循环抗阻训练（10项练习、3组循环，强度为1-RM的60%）。在运动前、运动结束后即刻以及运动方案实施后24小时采集血样。
生长激素、葡萄糖和C肽在运动结束后即刻显著升高，并随时间推移恢复至运动前水平。血浆胃饥饿素在运动结束后即刻显著降低，在运动后24小时显著升高。
总之，单次循环抗阻运动后血浆胃饥饿素降低表明，生长激素升高与血浆胃饥饿素水平无关。考虑到在长时间恢复期间急性运动诱发的食欲亢进。
