摘要

本研究的目的在探討胺基酸補充劑（精胺酸及鳥胺酸arginine ＆ ornithine各20mg/kg wt）對運動選手體能表現的影響，本研究以十名男性舉重選手爲對象，除正常的舉重訓練外，每天給予胺基酸補充劑(arginine, ornithine)或安慰劑(glucose) 40 mg/kg wt，爲期30天，之後再停用胺基酸補充劑及安慰劑，爲期30天，然後再給予胺基酸補充劑或安慰劑。本研究以雙盲及隨機交叉方式處理。比較舉重選手在使用胺基酸補充劑時，體重、身高、去脂體重的變化。運動表現是以測量背肌力、下肢推蹬力及無氧動力爲測量根據。本研究並測量GOT、GPT、creatinine、BUN等血液生化分析來評估受試者服用胺基酸補充劑的安全性。結果顯示：(l)體重、身高沒有變化，(2)去脂體重(FFM)胺基酸組後測較前測顯著增加，而安慰劑組不變，(3)胺基酸組體脂肪百分比後測較前測顯著下降，安慰劑組則沒有差異，(4)背肌力、下肢推蹬力兩組之間沒有差異，(5)最大無氧動力胺基酸組後測較前測顯著增加，安慰劑組沒有差異，(6)平均無氧動力、動力遞減率兩組之間沒有差異，(7)整個實驗期受試者維持健康狀態。研究顯示精胺酸及鳥胺酸補充劑有助於增加去脂體重及最大無氧動力，40 mg/kg wt的胺基酸補充不影響受試者的健康情形。

The purpose of this study was to investigate the physiological effect of amino acid supplementation on physical performance in elite athletes during weightlifting training. Ten elite male weightlifters served as experimental subjects. During normal training period, the subjects took either a placebo or an arginine (A) plus ornithine (O) supplement for a total of 30 days followed by a 30-day washout period; and then resumed the A plus O supplement or placebo. A double blind, counter-balance design was used. Body weight, height, fat free mass, back muscle strength, leg power and anaerobic power were measured to evaluate the physical performance of the athletes. Health safety of using these amino acids was checked by measuring blood GOT, GPT, creatinine, BUN. The results showed: 1) no statistically significant difference in body weight or height, 2) a significant increase in fat free mass in the amino acids supplement group between pre-test and post-test, and there was no significant difference in the placebo group, 3) a significant decrease in the percentage of body fat in the amino acids supplement group between pro-test and post-test, and no significant difference in the placebo group, 4) no significant difference in back muscle strength and leg power, 5) a significant increase in peak anaerobic power in the mino acids supplement group between pro-test and post-test, and no significant difference in the placebo group, 6) no significant difference in mean anaerobic power and power decline, and 7) no ill effect on the athletes throughout the experimental period. These results indicate that arginine plus ornithine supplement during a 30-day period of intense weightlifting training resulted in an increase in fat free mass and peak anaerobic power, and that 40 mg/kg wt of amino acid supplement did not have a short term ill effect on the athletes' health.
