Differences in catabolic capacity in the pectoralis major muscle of premigratory and migratory Reed Warblers were examined. The oxidative capacity was greater in the migratory birds, probably reflecting a "training effect" caused by the increased locomotion activity just prior to migration.Fatty acid oxidation was already high in the premigratory birds, possibly reflecting a saving of carbohydrate for anabolic purposes (feather growth) during the moult. Glycolytic capacity was slightly increased in the migratory birds, suggesting an increased carbohydrate oxidation during migration in spite of the great contribution of fatty acid oxidation.
研究了迁徙前和迁徙中的苇莺胸大肌分解代谢能力的差异。迁徙鸟类的氧化能力更强，这可能反映了迁徙前运动活动增加所产生的“训练效应”。迁徙前的鸟类脂肪酸氧化水平已经很高，这可能反映了在换羽期间为合成代谢目的（羽毛生长）节省碳水化合物。迁徙鸟类的糖酵解能力略有增加，这表明尽管脂肪酸氧化起了很大作用，但在迁徙过程中碳水化合物氧化仍有所增加。
