目的：探讨乳酸阈在皮划艇项目有氧能力监控中的应用方法。方法：以13名国家皮划艇队1000m组男子皮艇（7人）和划艇运动员（6人）为研究对象，在皮划艇航道水面上分别完成4级递增负荷的1000In划船测试，记录成绩、心率、乳酸、风速和水温，以4mmol／L乳酸对应的船速（m／s）为乳酸阈速度，同时测试晨血红蛋白、肌酸激酶和血尿素，以上述方法对国家皮划艇队伦敦奥运年训练周期进行了6次系统监控。结果：乳酸阈速度与皮划艇专项成绩密切相关（男子皮艇r=-0．889，P=0．018；男子划艇r=-0．951，P=0．004），在对不同测试日风速、水温进行校正及机能状态的比较后，发现不同训练周期，皮划艇运动员乳酸阈速度呈现明显的变化，表现出很强的训练敏感性。结论：乳酸阈速度适于监控皮划艇运动员有氧能力的变化，但需要对测试条件和实验对象的机能状态进行严格控制。

Objective：To investigate the application of lactate threshold in canoeing event. Methods ： 13 China national canoeing team athletes were studied, including 7 kayakers and 6 canoeists of 1 000 m event. They finished 4 stepwise graded 1 000 m paddling, and the time, heart rate, blood lactate, wind speed and water temperature were recorded in all paddling. Lactate threshold was determined as the boat velocity corresponded to 4 mm01/L lactate, The haemoglobin, CK and BUN of the athletes were also measured in the morning, this model was applied 6 times to monitor the aerobic capacity of china national canoeing team in the last yearly training cycle during the preparation of London Olympic games. Result： The results showed that 1 000 m performance was significantly correlated with lactate threshold（ men kayak r= -0. 889,P=0. 018;men canoe r=-0. 951 ,P=0. 004）, lactate threshold changed significantly in different training periods and demonstrated strong trainability after the correction of wind speed, water temperature and physiological parameters in different tests. Conclusion ： Lactate threshold can be applied to monitor the development of aerobic performance in canoeing event, but the test condition and physiological status must be controlled strictly.
