本研究目的在探討過重或肥胖的健康成年女性，介入共軛亞麻油酸補充劑及環狀運動訓練後，對身體組成、血液生化值與肌力的影響情形。受試對象為年齡為20-50歲且為過重或肥胖的成年女性；其中20位為Curves®女性專用30分健身中心之新竹長春、光復及中山店會員，另外23位則為無規律運動之自願參與者，共計43位。以雙盲、配對的方式進行本研究，受試者依配對方式分配為CE組13人（年齡31.00±6.87歲；身高160.90±4.62；體重64.02±8.96公斤）、PE組) 7人（年齡30.39±8.89歲；身高162.79±3.49；體重65.49±12.30公斤）、C組12人（年齡26.03±6.23歲；身高161.43±4.90；體重64.26±7.94公斤）及P組11人（年齡31.06±9.34歲；身高158.31±3.79；體重64.74±9.83公斤）。
CE組、PE組、C組、P組分別給予混合型式的CLA膠囊加環狀訓練、安慰劑加環狀訓練、混合型式的CLA膠囊及安慰劑等為期12週的實驗介入。補充劑分別為混合型式共軛亞麻油酸膠囊3.4公克/天或玉米澱粉膠囊3.4公克/天，運動訓練則為環狀運動訓練為每週3次，每次30分鐘，前7週進行基礎的環狀運動訓練，後五週則進行進階環狀運動訓練。在實驗第1、12週進行全身及各部位體脂肪和瘦體組織、血脂、血糖和胰島素濃度及手部和腿部的等長肌力等檢測。所得數據以單因子共變數分析比較四組身體組成、血液生化及肌力等參數於補充或訓練前後之差異，統計顯著水準皆訂為α=.05。結果顯示：1.各組在各項身體組成等參數上，皆無顯著變化；2.各組在各項生化數值的檢測上，雖然沒有顯著效益，但也不會造成不良的影響；僅發現各組HDL-C濃度有顯著下降的情況，但此結果與補充劑的服用或環狀運動的介入並沒有關聯性；3.各組在手部等長肌力的變化上也無顯著變化。因此，為期12週每天給予3.4公克CLA補充或環狀運動介入，對於過重或肥胖的成年女性並無法達到減脂之實質效益。

The purpose of this study was to evaluate the effects of twelve weeks conjugated linoleic acid supplementation, and circuit exercise training on body composition, blood biochemistry and fitness in the overweight or obese adult women.
Forty three female overweight or obese adult women (age 20-50 years) were recruited, 20 as Curves® members from Curves® women fitness center (Changchun, Guangfu, and Jhongshan in HsinChu) and 23 volunteered participants to participate in this study. The trial was performed as double-blind, placebo-controlled study with four parallel groups. The subjects according to the paired and randomly assigned into the CE group (13 peoples, age: 31.00±6.87 years, Ht: 160.90±4.62 cm, Bwt: 64.02±8.96 kg), the PE group (7 peoples, age 30.39±8.89 years, Ht: 162.79±3.49 cm, Bwt: 65.49±12.30 kg), the C group (12 peoples, age 26.03±6.23 years, Ht: 161.43±4.90 cm, Bwt: 64.26±7.94 kg) and the P group (11 peoples, age 31.06±9.34 years, Ht: 158.31±3.79 cm, Bwt: 64.74±9.83 kg).
The CE group, PE group, C group, P group were given a mixed type of CLA capsules with circuit exercise training, and placebo with circuit exercise training, and the mixed type of CLA capsules and placebo of twelve weeks for this study. The supplementation were mixed type of conjugated linoleic acid capsules of 3.4 g/day and 3.4 g/day of corn starch capsules, the exercise training were circuit exercise training for 30 minutes/day, three times a week, for 12 weeks. During 1-7 weeks were elementary circuit exercise training, during 8-12 weeks were advanced circuit exercise training. The body composition of whole body and various parts of the body (BFM, %fat, and LBM), blood lipids (TG, TC, LDL-C, and HDL-C) , glucose AC, insulin concentration, and fitness (isometric strength) would evaluate during the firs and 12th weeks in the study. A mixed design, one-way ANCOVA was used to evaluate the difference between groups after program for each parameter. The statistic significance was set atα=.05. After 12 weeks, the results showed that: 1). no significant difference on body composition for any groups; 2). No adverse effects or indexes of blood biochemistry data were observed. A reduction in the HDL-C concentration was found in all the groups after 12 wk of treatment. The any group showed significant reduction in HDL-C concentrations, but this result significant significantly decline, but this result, the null association between this result and CLA supplementation or circuit exercise training; 3). no significant difference on isometric strength of the hand for any groups. Therefore, a 3.4g/day CLA supplementation or 30 minutes/day, three times a week circuit exercise training for 12 weeks was proven no effect on body composition, blood biochemistry and sport performance in the overweight or obese adult women.
