摘要


一直到1960年代為止,教練和選手都還認為耐力性運動項目的成功因素之一,就是在比賽中不能喝水或其他飲料。甚至有些教練訓練選手時,還限制選手喝水。1970年代以後,研究報告才證實身體缺水(dehydration)不僅對運動成績有負面影響,而且也不利於體溫調節。本文就身體缺水對有氧運動、肌力和無氧動力的成績表現做文獻探討,希望提供運動教練、選手和體育老師做參考,尤其是針對頂尖選手的訓練,以體重分級的運動項目更是重要。因為比賽前的最後訓練階段和比賽時的表現都和肌力、最大無氧動力、最大有氧能力息息相關。

Until 1960's coaches and athletes believed that tolerate to thirsty and not to drink was an important factor to success in the endurance event. Some coaches even restricted their ath1etes to ingest fluid during the training. However, research data demonstrated that dehydration not only have negative impact on exercise performance but also on temperature regulation. This paper reviewed the effect of dehydration on exercise performance, specifically, in terms of aerobic exercise, physical work capacity, muscle strength, and anaerobic power. Research data and its implication to coaches and ath1etes are very important. The author suggest that athlete hydration status needs to be evaluated carefully, especially, using body weight as criteria to classify different competition events.
