乳酸是能量代謝之最終產物。運動後血液及肌肉中乳酸濃度常被當做運動強度指 數。近年來，由於乳酸測量技術之進步及檢測儀器之大量製造，使得許多教練及研究人員能 夠經常在運動時進行乳酸檢測以做為預測運動表現及做為開立運動處方之基本依據，因此建 立乳酸測量值之精確而敘述完整之分析就顯得十分重要。研究結果發現運動強度與訓練狀 態、肌肉型態、營養物質、運動型態與恢復方式等與受測者本身有關、高地運動與環境有關、 血樣採集部位則與採樣方式有關。 本篇文獻回顧之目的旨在探討影響運動時乳酸測量之因素。了解這些因素對乳酸變數之 影響程度是培養以乳酸濃度分析訓練效果之準確性及專業性之基本要求。

　　　　　The purpose of this article was to review factors that influence lactate measurement during exercise. To understand those factors is of importance in developing an accurate and professional lactate analysis. Lactate is a metabolic end product. Post-exercise lactate levels have been considered as an index for measuring exercise intensity. Because of improvement in measuring technology, many coaches and researchers, in recent years, have had an opportunity to use a lactate analyzer to assay lactate levels generated during exercise. Lactate data has been applied to predict exercise performance and to establish exercise prescription. From the scientific studies, it is has been found that test subjects (exercise intensity and training status, muscle fiber type, substrate utilization, type of exercise, and recovery), environment (altitude and ambient temperature), and blood sampling techniques must all be considered when performing lactate measurements.
