本稿ではスポーツ医学におけるDXA法の役割・活用について、実際の事例にふれつつ紹介していきたい。. DXA法は測定誤差が比較的小さいため、競技の時期に応じて体組成が変化するアスリートの経時評価に適している。. 特に陸上長距離走のように、自身の 鑑於版上及其他地方都沒有看到台灣地區DXA (DEXA)體脂肪檢測的心得， 在這裡分享一下，大家以後可以當作一個選項。. （Mobile01有國外地區DEXA檢測的心得一篇，請參考） DXA儀器是做骨質密度測量的儀器，在台灣各醫院幾乎都有， 但配備身體組成檢測分析軟體的 Dual-energy X-ray absorptiometry (DXA) is an accurate and reliable method for determining body composition, but a limiting feature is the restricted scanning areas (∼190 × 60 cm2). This Dual-energy X-ray absorptiometry (DXA, or DEXA) is a means of measuring bone mineral density (BMD) using spectral imaging.Two X-ray beams, with different energy levels, are aimed at the patient's bones.When soft tissue absorption is subtracted out, the bone mineral density (BMD) can be determined from the absorption of each beam by bone. Dual-energy X-ray absorptiometry is the most widely used DXA (dual-energy X-ray absorptiometry) 雙能量 X 光吸收儀，除了能測量骨密度，也可以用來分析身體組成，看肌肉、體脂肪的量和百分比。平常用的體脂機，就是用 BIA 的原理。但是 BIA 會受身體水分的影響，或是手掌潮濕都會使測定結果不準。用 DXA 分析身體組成，誤差會比生物阻抗分析的儀器小，是相對 Objective To present an updated and evidence-based guideline for the use of dual-energy x-ray absorptiometry (DXA) to assess body composition in clinical practice.
