中文摘要 | 前之研究發現一週之中低強度有氧運動會導致血漿支鏈胺基酸濃度顯著降低。為了探討高醣配方飲食添加支鏈胺基酸對運動之生理影響,乃進行此雙盲交叉之運動營養實驗。十九位男性大學運動員隨機分配成二組:安慰劑組及支鏈胺基酸(2.2克)組,均於空腹期攝取高醣配方飲食(~84%醣類,~13大卡/公斤體重),一小時後,進行衰竭運動(85%最大攝氧量,10%斜度),運動前、中、後均取血及採氣,衰竭狀態則根據最大心跳率,呼吸交換率及漿乳酸值判定。結果發現:安慰劑組之血漿支鏈胺基酸濃度顯著低於、而色氨酸/支鏈胺基酸之比則顯著高於支鏈胺基酸組(p<0.05)。運動時,安慰劑組之血漿支鏈胺基酸濃度也隨著運動時間之延長而逐步顯著減少(p<0.05),而支鏈胺基酸組者則不變。安慰劑組較之支鏈胺基酸組運動較早衰竭但未達顯著水準(p=0.43)。至於運動前後體重之改變,最大心跳率,最大攝氧量,呼吸交換率及血漿乳酸值等生理值,二組則無分軒轅,本研究結果認為支鏈胺基酸補充劑有助於運動耐力之傾向。 |
英文摘要 | Previous study found that plasma branched-chain amino acid (BCAA) concentrations were significantly decreased after 7 days of low/moderate aerobic exercise. To understand the physiological homeostasis of adding BCAAs to the carbohydrate (CHO) diet which is believed to enhance exercise performance, the present double blind and crossover study was undertaken. Nineteen male college athletes, randomly divided into 2 groups: placebo and BCAAs (2.2 g), were employed and, in the postabsorptive state, all received a high CHO ( ~ 84%) formula diet ( ~13 kcal/kg BW) 1 hour before an exhaustion exercise program ( 85% maximal oxygen consumption [VO□], 10% grade). Blood samples were taken before, during, and after the exercise program. The exhaustion was determined by the measurements of maximal heart rate (HRmax), respiratory exchange ratio (RER), and plasma lactate concentration. The plasma BCAA concentrations were significantly lower (p < 0.05) and the ratios of f-tryptophan/BCAAs were significantly higher (p < 0.05) in the placebo group than those in the BCAAs group, measured at the same time interval. During the exercise, the BCAA concentrations, both the individual and total, in the placebo group decreased significantly (p < 0.05) whereas those of the BCAAs group remained constant. Exercise time to exhaustion was shorter in subjects receiving placebo although the difference did not reach a significant level (p = 0.43). No differences in body weight changes, HRmax, VO□, and RER were observed between the two groups nor in the plasma lactate concentrations measured at the same time interval. The results suggest that BCAAs supplements tend to increase exercise endurance. |
