摘要
目的：探討不同處理方式的兒茶素 (EGCG) 和咖啡因 (CAF) 攝取對運動能量消耗與脂質代謝的影響。方法：選取12名健康的大專男性 (年齡：24.6 ± 1.3yrs；身高：175.4 ± 4.5cm；體重：72.9 ± 9.6 kg) ，依平衡次序、重複量數方式在攝取EGCG + CAF、EGCG、CAF和安慰劑 (CON) 後，給予固定 65 ± 5 % 最大保留心跳率 (% HRR) 強度的固定速率有氧運動30分鐘，安靜期、運動期和恢復期全程觀察心跳率、攝氧量和血液生化值。結果： 運動期的呼吸交換率在EGCG + CAF (0.82 ± 0.03) 顯著小於EGCG (0.84 ± 0.03) 、CAF (0.84 ± 0.02) 和CON (0.84 ± 0.03) (p < .05) ；而運動期脂質代謝率EGCG + CAF (36.8 ± 7.5 KJ/min) 顯著大於EGCG (32.4 ± 7.1 KJ/min) 、CAF (31.7 ± 6.4 KJ/min) 和CON (30.9 ± 7.8 KJ/min) (p < .05)。恢復期運動後過攝氧量EGCG + CAF (59.49 ± 23.94 ml) 顯著大於EGCG (46.23 ± 15.62 ml) 、CAF (44.96 ± 23.28 ml) 和CON (41.52 ± 18.72 ml) ( p < .05) 。而恢復期甘油濃度EGCG + CAF (209.93 ± 104.34μmol/l) 和CAF (186.78 ± 77.87μmol/l) 顯著高於CON (134.39 ± 79.13μmol/l) (p < .05)。結論：同時攝取EGCG + CAF對運動可提升的脂質代謝與能量消耗，且CAF是提升恢復期脂質代謝的主要物質。對於想減重者除了規律運動的養成外，可搭配一些增補劑來提升更多的脂質代謝和能量消耗。

Purpose: To investigate different sequence of catechins (EGCG) and caffeine (CAF) intake on exercise lipid metabolism and energy expenditure. Methods: By counter-balanced crossover design, twelve health males (age: 24.6 ± 1.3 yrs; height: 175.4 ± 4.5 cm; weight: 72.9 ± 9.6 kg) performed a 30-min treadmill exercise at 65 ± 5 % of heart rate reserve (% HRR) after supplementation of EGCG + CAF, EGCG, CAF, control (CON). Heart rate, oxygen uptake, and blood biochemistry parameters before exercise, during exercise, and post-exercise were compared. Results: During exercise, there were significant lower respiratory exchange ratio at EGCG + CAF (0.82 ± 0.03) than EGCG (0.84 ± 0.03), CAF (0.84 ± 0.02), and CON (0.84 ± 0.03); fat oxidation rate was significant by higher at EGCG + CAF (36.8 ± 7.5 KJ/min) than EGCG (32.4 ± 7.1 KJ/min), CAF (31.7 ± 6.4 KJ/min), and CON (30.9 ± 7.8 KJ/min) ( p < .05). For post-exercise, there were significant higher excess post exercise oxygen consumption at EGCG + CAF (59.49 ± 23.94 ml) than EGCG (46.23 ± 15.62 ml), CAF (44.96 ± 23.28 ml), and CON (41.52 ± 18.72 ml) (p < .05); plasma glycerol was significant by higher at EGCG + CAF (209.93 ± 104.34μmol/l) and CAF (186.78 ± 77.87μmol/l) than CON (134.39 ± 79.13μmol/l) (p < .05). Conclusion: While intake of EGCG + CAF in exercise can enhance lipid metabolism and energy expenditure, CAF is the main ingredient that enhance lipid metabolism during recovery. For those who want to lose weight in addition to have regular exercise, supplements can be used to enhance lipid metabolism and energy expenditure.
