Effects of Glutamine Peptide Supplementation on Lipolysis and Plasma IL-6 Concentration after Endurance Exercise
耐力運動後補充麩醯胺酸胜肽對脂肪分解及血漿IL-6濃度的影響
摘要
本研究目的在探討耐力運動後補充麩醯胺酸胜肽對恢復期血漿IL-6、生醣性胺基酸及脂肪分解的影響。實驗採用隨機雙盲交叉設計，研究對象為7名健康之大學男性學生，以強度75%V_4 O_2max之跑步機耐力運動60分鐘後補充麩醯胺酸胜肽或安慰劑 (0.1 g/kg．bw)，於運動前、運動後第0、15、30、45、60、90及120分鐘時採集血液進行生化值之分析，檢定麩醯胺酸胜肽組(GP)及安慰劑組(PL)補充在運動前後各血點與兩組間各血點之差異。研究結果顯示：IL-6濃度在運動恢復期45及60分鐘時，GP組顯著高於PL組；甘油濃度在運動恢復期60及90分鐘時，GP組顯著低於PL組；生醣性胺基酸濃度在運動恢復期30分鐘時，GP組顯著高於PL組；血糖、胰島素及游離脂肪酸濃度在運動恢復期時，兩組之間並無顯著差異。本研究結論：運動恢復期補充麩醯胺酸胜肽，可增加升醣性胺基酸濃度、抑制脂肪分解作用並且增加血漿中IL-6的濃度。

The purpose of this study was to investigate the effects of glutamine peptide supplementation on plasma interleukin-6 (IL-6), glucogenic amino acids and lipolytic metabolite during recovery after endurance exercise. In this crossover designed study, seven healthy male college students completed either placebo (PL) supplementation or glutamine peptide (GP) supplementation trial in a randomized order. The subjects were assigned to run on a treadmill at an estimated speed corresponding to their 75% V_4 O_2max values for 60 min, where after the GP trial received 0.1 g/kg ． bw glutamine-peptide solution and the PL trial received hydroxypropyl methylcellulose solution. The biochemical parameters in the blood sample were measured pre-exercise, and after exercise at 0, 15, 30, 45, 60, 90 and 120-min. Plasma IL-6 concentration was significantly greater in GP trial at 45 and 60 min during recovery periods. Furthermore, plasma glycerol was also significantly greater in GP trial during recovery at 60 and 90 min following exercise. Glucogenic amino acids in the GP trial were significantly increased at 30 min during recovery. Nevertheless, we found no significant differences in glucose, insulin and free fatty acid concentrations for both trials during recovery periods. In conclusion, the present study demonstrated that the GP supplementation can increase glucogenic amino acids, inhibit lipolysis and enhance plasma IL-6 concentrations in young adults during recovery following exercise.
