摘要 目的:探討比賽期肌酸增補對短跑選手血氨、血乳酸及速度運動表現之影響。方法:14位短跑選手進行4週比賽期肌酸增補(前5天攝取0.3g/kg/day,之後23天增補3g/day)及4週washout的模擬比賽期訓練,於二實驗期程之前、後分別進行60公尺衝刺的速度測驗,並採集60公尺測驗時第一、三、五趟前後的血液樣本,進行血氨及乳酸值分析。結果:肌酸增補前、後之60公尺反覆運動血氨濃度變化達顯著差異(p < .05),而增補前、後60公尺速度表現(7.49 ± 0.42s~7.62 ± 0.44s vs. 7.42 ± 0.42s~7.58 ± 0.52 s)及乳酸值變化則無顯著差異。結論:肌酸增補能改善短跑選手60公尺運動之血氨濃度,但對60公尺速度表現及運動後乳酸值則無影響。 Purpose: To examine the effect of creatine supplementation on 60 m performance as well as blood ammonia and lactate in sprinters during competition period. Methods: Fourteen sprinters ingested 0.3 g/kg/day for 5 days and followed 3 g/day for 23 days and performed 4 weeks of washout period. All participants performed a repeated sprint test consisting of five maximal 60 m tests with 3 min rest. Blood samples were obtained at rest and immediately after 1, 3, 5 bout of the 60 m sprint test to determine the ammonia and lactate concentrations. Results: A significant change of blood ammonia in the first bout of 60 m sprint test were observed after creatine supplementation (p < .05). There were no differences in 60 m sprint performance (7.49 ± 0.42 s~7.62 ± 0.44 s vs. 7.42 ± 0.42 s~7.58 ± 0.52 s) and change of blood lactate during the 60 m sprint tests (p > .05) after creatine supplementation. Conclusions: Creatine supplementation during competition period can reduce blood ammonia after exercise in sprinters. However, the 60 m sprint performance and blood lactate were not affected by creatine supplementation.
