Methods: eight trained male college kayak sprint athlete (age 19.8 years ± 0.51, height 172cm ± 1.69cm, weight 67.25kg ± 1.43kg) trailed maximum oxygen uptake, 200 meters, 500 meters, 1000 meters on kayak ergometer and converted the critical velocity. Blood lactate, hart rate were recorded instantly end of four minutes different percentage intensity of critical velocity ergometer kayaking. result: 1. An acute blood lactate concentration responses were significant difference at end of the different percentage critical velocity exercises (between 80% of CV, 90% of CV and 100% of CV, p <.01, and between 80% of CV, 90% of CV and 110% of CV, p <.01) but no significantly between 100% of CV and 110% of CV. 2. The percentage of maximum heart rate at end of different CV intensities were significant difference between 80% of CV, 90% of CV and 100% of CV (p <.01) and between 80% of CV, 90% of CV and 110% of CV (p <.01) but not between 100% of CV and 110% of CV. 3. A significantly correlation between with VO2max and 110% of CV(r = -0.757, p <.05), and between with1000m time trail and 110% of CV(r = 0.821, p <.05). Conclusion: According to ergometer kayaking, the magnitude of increase in blood lactate concentration and heart rate were regulated in a percentage of critical velocity-dependent manners. A different percentages of critical velocity can be directly corresponds to the intensity on ergometer kayak specialized training.
