本研究乃針對補充含有支鏈胺基酸及精胺酸之市售胺基酸複合飲料對力竭運動恢復期血液生化值之影響進行探討。本實驗採用隨機交叉雙盲設計，研究對象為14位健康男性，進行75 %VO2 max強度之跑步機運動至力竭後立即隨機分派飲用100 mL的AA (胺基酸複合飲料) 或PL (安慰劑)，經過14天的排空期，再完成第2次的力竭運動並飲用PL或是AA。記錄運動前與恢復期的心跳率，並於運動前、力竭點以及運動後10、20、40、60、120分鐘進行靜脈採血，24小時後進行指間採血測CK活性。本研究結果顯示，兩組之ammonia、lactate、CK、心跳率均無顯著差異。然而，AA組之血糖在恢復期第40及60分鐘顯著高於PL組 (94.7 ± 4.5 mg/dL vs. 83.1 ± 2.8 mg/dL, 85.2 ± 4.2 mg/dL vs. 75.4 ± 1.3 mg/dL, p＜.05)，AA組之胰島素在恢復期第40和60分鐘顯著高於PL組 (31.6 ± 5.6 μlU/mL vs. 15.5 ± 2.6 μlU/mL, 30.1 ± 7.1 μlU/mL vs. 10.6 ± 1.1 μlU/ mL, p＜.05)，游離脂肪酸於恢復期第60和120分鐘AA組顯著低於PL組 (0.18 ± 0.22 mmol/L vs. 0.3 ± 0.1 mmol/L, 0.4 ± 0.1mmol/L vs. 0.6 ± 0.1 mmol/L, p＜.05)。本研究結果顯示，補充胺基酸複合飲料可使恢復期血糖和胰島素濃度增加，降低FFA濃度，有助於恢復期能量的補充。

This study investigated the effects of amino acid compound beverage which includes branched-chain amino acid and arginine on acute metabolic responses during recovery of exhaustive exercise. Fourteen healthy males were assigned to drink either amino acid compound beverage (AA) or placebo (PL) in two sessions separated by 2 weeks. The heart rates were recorded before exercise and during recovery period. Blood samples of each athlete were collected before exercise, and 0, 10, 20, 40, 60, 120 minutes and 24hr after exhaustive exercise, respectively. There were no significant differences in the levels of lactate, ammonia, and CK between the two groups were observed at any of the time points. However, the concentration of glucose was significantly higher in the AA group as compared to that in the PL group at the 40 and 60-min recovery period (94.7 ± 4.5 mg/dL vs. 83.1 ± 2.8 mg/dL, 85.2 ± 4.2 vs. 75.4 ± 1.3 mg/dL, p＜.05); the insulin activity was higher in the AA group than that in the PL group at the 40 and 60-min of recovery period (31.6 ± 5.6 μlU/mL vs. 15.5 ± 2.6 μlU/mL, 30.1 ± 7.1 μlU/mL vs. 10.6 ± 1.1 μlU/ mL, p＜.05). Furthermore, the free fatty acid levels at the 60 and 120-min recovery period were significantly lower in the AA group as compared to that in the PL group (0.18 ± 0.22 mmol/L vs. 0.3 ± 0.1 mmol/L, 0.4 ± 0.1 mmol/L vs. 0.6 ± 0.1 mmol/L, p＜.05). The results indicate that consuming amino acid compound beverage during exercise recovery period could increase glucose and insulin concentration, and decrease FFA level in blood. Thus, amino acid compound beverage supplementation may benefit to energy recovery after exercise.
