目的：研究静水皮艇500m能量供应特征。方法：选取8名青少年女子皮艇运动员（年龄15±1岁，身高172±4cm，体重65±5kg，训练年限15±10年）在Dansprint皮艇测功仪上进行多级测试和120S的最大测试，结合测功仪和气体代谢数据，运用累积氧亏法（AOD）进行能量供应比例的计算。结果：静水皮艇500m有氧供能的比例为59．6％±11．4％，最大心率为179土8bpm，最高血乳酸为11．3±1．5mM／L。全力运动的前5～10S以磷酸原供能为主，第10-40s期间糖酵解供能占据重要地位，40S之后影响运动能力的主要为有氧供能。结论：静水皮艇500m是一个以有氧供能为主的运动项目，国内对此项目供能特征的认识低估了有氧供能的作用；静水皮艇500m能量供应的时序特征可以作为安排训练、发展不同供能系统的重要生物学基础。

Objects：Energetic profile of 500m kayak sprint was researched. Methods：Eight jun- ior female kayakers （ 15±1 yr, 172±4 cm, 65±5 kg, training experience 15±10 month） volunteered to participate in this research and paddled on Dansprint kayak ergometer for a step test and a 120s all-out test. Using information from ergometer and spirometric analyzer, the energetic contribution was measured with accumulated oxygen deficit （AOD） method. Results ： The energy of 500m kayak sprint was supplied with 59.6%±11.4% from aerobic system. The maximal heart rate and blood lactate acid during the 500m paddling were 179±8 bpm, and 11.3±1.5 mM/L, respectively. The energy of the first 5 to 10 seconds in 500m paddling was provided mainly by ATP-CP system. The glycolysis system played an important role from the 10th to 40th seconds. After 40s paddling, the aerobic system dominated the energy supply. Conclusion： Kayak sprint 500m is an aerobic dominated event. The knowledge of energy supply in this event in China underestimates the importance of aerobic contribution. The time-course character of en- ergetic supply in 500m kayak sprint could provide a biological background for the training.
