近年來運動禁藥的防治議題受到重視，除世界運動禁藥管制組織（World Anti-Doping Agency, WADA）與國際奧林匹克委員會（International Olympic Committee, IOC），尚有許多組織或政府機構對此制定規範及條款，以防範運動禁藥的濫用。在WADA禁藥清單中，酒精在特殊運動項目（particular sports, P1）中屬於賽內禁用物質，檢驗方式以藉由呼出氣體來檢測酒精濃度。目前國內禁藥檢測主要採用尿液檢體，酒精呼氣檢測與以往檢測方法有所不同，僅有特殊運動項目會進行酒精檢測，若檢驗結果被判為陽性，依違反禁藥處分規定會取消資格、禁賽等懲處。目前國內並無此方面之文獻，且酒精檢測在國內大型運動會之藥檢將為例行性檢測，故本文主要為探討WADA進行酒精呼氣檢測之目的與作業程序，以供國內教練及選手參考。

In recent years, the problem of doping in sports has been a major concern for World Anti-Doping Agency (WADA) and International Olympic Committee (IOC). Many organizations and government institutions have established regulations and protocols to prevent the abuse of doping in sports. In the prohibited list of doping, alcohol is a prohibited substance in particular sports, P1. The evaluation method is to conduct the evidentiary breath test to measure the amount of alcohol breathing out. Currently, the anti-doping test in Taiwan is based on the urine test for athletes. However, the breath method to test alcohol is different from the common tests in doping. The breath alcohol test is conducted only in certain sports. If the testing result is positive, the athlete will be disqualified and punished due to the violation of the anti-doping code. In Taiwan, no literature has examined the breath alcohol test. In the future, the breath alcohol test will be conducted in the major sport events as a routine. Therefore, the aim of this article is to report the purpose and the operating procedures of the breath alcohol test conducting by WADA in order to provide a useful reference for coaches and athletes in Taiwan.
