| 中文摘要: |
| 南极磷虾油是一种新型的天然海洋n-3多不饱和脂肪酸来源，含有丰富的磷脂、EPA、DHA、虾青素、维生素、微量元素等多种生物活性物质，具有抗炎特性和免疫功能。南极磷虾油可以改变细胞膜磷脂脂肪酸组成，调节细胞膜内炎症过程中脂筏的形成；可以通过抑制促炎转录因子NF-κB的激活从而减少炎性基因的表达；还可以通过作为PPAR和SREBP-1等转录因子的配体调节脂质和葡萄糖代谢等。在运动营养领域，运动员依靠营养策略来提高训练效果和成绩，南极磷虾油在提高运动代谢能力、延缓疲劳的发生及促进运动后恢复等方面受到极大的关注。对南极磷虾油对运动恢复的促进作用研究进展及相关机制进行综述，包括南极磷虾油改善运动后免疫抑制、氧化应激和缓解运动性骨骼肌损伤的作用及机制，以期为南极磷虾油在运动营养领域的研究提供新思路。 |
| 英文摘要: |
| The Antarctic krill oil is a novel natural marine source of n-3 polyunsaturated fatty acids, rich in various bioactive substances such as phospholipids, EPA,DHA, astaxanthin, vitamins and microelements. Its health effects mainly come from its anti-inflammatory properties and effects on immune function. Antarctic krill oil can change the composition of phospholipid fatty acids in cell membrane and regulate the formation of lipid rafts during the inflammatory process in cell membrane; it can reduce the expression of inflammatory genes by inhibiting the activation of the pro-inflammatory transcription factor NF-κB; it can also regulate lipid and glucose metabolism by acting as ligands for transcription factors such as PPAR and SREBP-1. In the field of sports nutrition, athletes rely on nutrition strategies to improve their training effect and performance. Antarctic krill oil has attracted great attention in improving exercise metabolism, delaying the occurrence of exercise fatigue and promoting post-exercise recovery. The advances in promoting the post-exercise recovery of Antarctic krill oil and its related mechanism were reviewed, including the effects and mechanisms of Antarctic krill oil in improving post-exercise immunosuppression, oxidative stress and alleviating exercise-induced muscle damage, in order to provide a new idea for the research of Antarctic krill oil in the field of sports nutrition. |
