| 目的：探讨我国优秀皮划艇运动员有氧能力的评价方法，为制定针对性的训练计划提供参考。方法：以备战伦敦奥运会国家皮划艇队运动员为研究对象，包括8名男子皮艇、7名女子皮艇和6名划艇运动员。利用皮划艇测功仪采用逐级递增负荷至力竭测最大摄氧量、利用4级1 000 m递增强度划船测试乳酸阈（4 mmol/l对应的船速）。结果：伦敦奥运周期我国优秀男子皮艇、女子皮艇和划艇运动员的绝对最大摄氧量分别为（5.25±0.22） l/min、 （3.58±0.22） l/ min、 （4.85±0.13） l/ min ;相对最大摄氧量分别为（57.28±3.8 1） ml/ （kg? min-1）、 （50.92±3.78） ml/ （kg?min-1）、（ 54.72±5.3） 1ml/（ kg?min-1）,，经过3个月训练后男子皮艇和划艇运动员最大摄氧量无明显变化，女子皮艇运动员明显提高；男子皮艇、女子皮艇和划艇运动员乳酸阈船速经过3个月的训练后都明显提高，提高幅度分别为11.92%、3.77%和14.37%。结论：我国伦敦周期优秀皮划艇运动员的最大摄氧量高于国际优秀皮划艇运动员的平均水平，和最大摄氧量比较，乳酸阈表现出更好的训练可塑性，能够更为准确的反映皮划艇运动员有氧能力的动态变化。 |

| To investigate the monitoring method of canoeing athletes in order to provide reference to the design of corresponding training programs. Methods: 8 male kayakers, 7 female kayakers and 6 canoeists from China National Canoeing Team, who were preparing for 2012 London Olympic Games, were chosen as the subjects. VO2max was measured by kayak ergometer with incremental exercise to exhaustion. Lactate threshold was measured with 4-grade 1000m incremental paddling (corresponding speed to 4mmol/l). Result: Absolute VO2max of male kayakers, female kayakers and canoeists were 5.25± 0.22 l/ min, 3.58±0.22 l/ min and 4.85 ±0.13 l/ min respectively. And the relative VO2max was 57.28 ± 3.81 ml/ kg? min-1, 50.92± 3.78ml/ kg?min-1 and 54.72 ± 5.31ml/ kg?min-1. There were no changes of VO2max of male kayakers and canoeists after 3-month training, but the VO2max of the female kayakers increased significantly. The lactate threshold of all the three groups increased by 11.92%, 3.77% and 14.37% respectively. Conclusion: VO2max of the elite Chinese canoeing athletes who were preparing for London Olympic Games is higher than that of the foreign canoeing athletes. Compared to VO2max, lactate threshold shows better training plasticity and can be applied to monitor the dynamic changes of aerobic performance in canoeing. |
