第五章 討論與結論
第四節 結論
本研究以 12 名健康男性，平日有運動習慣之受試者，補充共軛亞麻油酸毎 天 4 克持續 8 週。結果顯示身體組成並未改變 經過四週後，共軛亞麻油酸可能 會破壞其血糖的利用，以 ISI 指數測得之全身胰島素敏感性也顯著變差，建議日 後想以補充 CLA 改變人體身體組成者，應考慮身體葡萄糖的恆定及胰島素敏感 性改變所造成之影響。

研究題目：8 週補充共軛亞麻油酸對於年輕健康人體胰島素敏感性之影響
研究單位：國立台中教育大學 研究人員：施明谷
共軛亞麻油酸(Conjugated Linoleic Acid, CLA) 是一群含 18 個碳分子，具共 軛雙烯鍵的脂肪酸。CLA 對人類身體健康具有廣大的功效，特別是在身體組成 上，越來越多研究的焦點集中在 CLA 對於胰島素敏感性的功效，本研究將探討 八週口服 CLA 補充是否會影響有運動習慣者全身葡萄糖利用。在研究期間，受 試者須分別在補充 CLA 前、補充後四周及補充後八周分別進行三次口服葡萄糖 耐受度測驗(Oral Glucose Tolerance Test, OGTT)。所有受試者在受試前一天晚上 10 點後開始禁食（可少許飲用不含熱量的水），至受試當天早上 8:30 分接受測 試。口服葡萄糖耐受度試驗檢測流程為受試者在空腹狀況下飲用 75 公克葡萄糖 水搭配 500 毫升純水後開始計時（0 分鐘為基準值），空腹飲用糖水後分別在第 0、30、60、90、120、150、180 分鐘個別抽血，以含 EDTA 的真空採血管收集 3 毫升的靜脈血液供血液生化值分析。
附錄三 口服葡萄糖耐受度測驗步驟
1、所有受試者試驗前一晚隔夜禁食 10 小時（前一晚上十點後勿進食）。
2、於上午 8：30 至實驗室進行本試驗（先不吃早餐）。
3、受試者靜態休息約五分鐘後，由護士先進行第一次空腹抽血。
4、第一次抽血之後，將 75 公克葡萄糖與 500 毫升純水配置成之葡萄糖水，並要 求受試者於五分鐘之內喝完。
5、飲用葡萄糖水時指示受試者攪拌，飲盡時杯底勿殘留葡萄糖粉末。
6、攝取後開始計時，於第 30、60、90、120、150、180 分鐘，由護士使用無菌 拋棄式針頭與 5 ml 針筒，從受試者手部橈骨靜脈抽取 3 ml 靜脈血，置入含
