Abstract
運動時造成的肌肉損傷會使身體進行發炎反應,生理上降低了肌肉收縮之效率進而降低運動表現,更有可能對日常生活造成不便。諸多研究顯示,白藜蘆醇對於肌肉損傷具有抗發炎與降低氧化壓力的功能;此外,補充白藜蘆醇亦被證實可以加速挫傷後的肌肉修復與運動表現(如:有氧運動與抓力)之恢復。然而,肌肉容易以離心收縮的狀態下造成損傷,由於白藜蘆醇對於離心收縮所造成的運動傷害是否具有相同生理效益上尚未有明確的定論。因此,本研究以離心收縮誘導肌肉損傷的小鼠動物模式,進一步探討白藜蘆醇對其抗發炎、抗氧化及能量代謝的影響,並觀察是否因白藜蘆醇補充達到改善運動表現;並利用RNA sequencing的方法,驗證肌肉中能量利用、抗發炎及抗氧化相關基因表現量是否有因為離心損傷運動與白藜蘆醇的增補而有所調節,並進一步探討白藜蘆醇可能的調節機轉。本實驗分為長期及短期下坡跑誘導小鼠離心損傷並介入白藜蘆醇,共分成四組,控制組(NC)、運動組(EX)、運動搭配低劑量白藜蘆醇組(EX+RES25)及運動搭配低劑量白藜蘆醇組(EX+RES150)。長期下坡跑力竭結果顯示,介入白藜蘆醇的兩組進行力竭跑的時間均顯著長於EX組;EX+RES150組之GLUT4 mRNA表現量顯著高於EX組,AMPK α1 mRNA表現量則是因為運動而使得EX組、EX+RES25組及EX+RES150組高於NC組。透過RNA sequencing發現長期介入白藜蘆醇後,相較於抗發炎及抗氧化,能量利用的效果較顯著。短期下坡跑力竭結果顯示,EX+RES150組跑的時間長於EX組;TNF-α mRNA表現量方面,EX+RES150組均比EX組低;能量利用的部分,EX+RES150組在不同肌肉中帶來的效果較EX+RES25組顯著。因此,透過本實驗得知長期及短期介入高劑量白藜蘆醇均可以提升運動中肌肉對能量的利用,而短期介入白藜蘆醇對發炎及氧化的效果較長期為佳。
