Abstract:	本研究目的為探討β-丙氨酸增補對西式划船選手的運動表現及抗氧化能力的影響。以22名高中男子划船選手為受試對象，以S型分配方式，分為β-丙胺酸組（n=10）與安慰劑組（n=12），進行四週β-丙胺酸增補。受試者於增補前後皆接受遞增負荷測驗及三分鐘划船衰竭測驗。研究結果顯示，三分鐘划船衰竭測驗之結束功率與高於結束功率總作功專項有氧及無氧能力評估指標、血乳酸值，遞增負荷測驗之最大攝氧量、血乳酸值，及三分鐘測功儀衰竭測驗的抗氧化能力評估指標pH值及丙二醛、超氧化物歧化酶，β-丙氨酸組及安慰劑組在增補前後皆無顯著差異。本研究發現四週的β-丙氨酸增補無法增進西式划船選手的運動表現，也無法改善抗氧化能力，建議未來研究可針對較長時間的增補作進一步探討。 The purpose of this study was to investigate the effect of β-alanine supplement on post exercise performance and their antioxidant ability of rowing athletes. Twenty-two high school rowing athletes were recruitedn the S-type distribution method, and were assigned to two groups: β-alanine (n=10) and placebo (n=12). Four weeks of supplement test were conducted on both groups. All participants performed graded exercise loading test and 3-min all-out rowing tests before and after the 4-week supplement test. The result shows that no significant differences were found on athletes' post exercise performance (end-test power, work done above the end-test power, max, Lactic acid) or their antioxidant ability (Malondialdehyde, Superoxide dismutase) at pre- or post-supplementation between two groups (p＞.05). Four-week β-alanine supplement improves neither the athletes' performance nor their antioxidant ability. Future studies could investigate the effects of supplement with longer period of time.
