摘要

在熱環境下從事耐力運動時，核心溫度與熱調節壓力的增加，是降低運動表現與產生熱疾病的主因之一。過去研究發現，攝取冷飲可能是透過多種生理機制（降低核心溫度、心血管壓力、熱調節壓力、溫度感覺或自覺努力程度等）以促進耐力表現。目的與方法：透過蒐集相關文獻並加以整理，探討攝取冷飲對耐力表現之影響。結果與結語：不論在運動前或運動中，攝取冷飲皆有助於提升在熱環境下之跑步機或固定式腳踏車耐力表現。攝取策略上，在運動中以平均攝取率1.00至1.26公升／小時，攝取4°C冷水，或於運動前30分鐘內，攝取約550至600毫升，溫度為-1至1.4°C的冰沙，可能對耐力表現有所助益。

Exercise in a hot condition, increases in the core temperature and thermoregulatory strain are considered as the main factors of reducing exercise performance and inducing heat disease. Previous studies found that cold beverage ingestion could improve exercise performance due to several physiological mechanisms (e.g., decreases in core temperature, thermoregulatory strain, thermal sensation, and ratings of perceived exertion). Purpose and Methods: The aim of this study was to investigate the effects of cold beverage ingestion on endurance exercise performance through reviewing previous studies. Results and Conclusion: Cold beverage ingestion may benefit the endurance exercise performance, such as running or cycling, in the heat, regardless of drinking prior to or during exercise. Ingestions of ice slurry (-1 to 1.4°C, 550-600 ml) within 30 min before exercise or cold water (4°C) with drinking rate from 1.00 to 1.26 L.hr-1 during exercise may be a useful strategy to increase endurance exercise performance.
