Use the special dynamometer for kayak to simulate and analyze the gas metabolism characteristics of high-level kayakers at different stages of the competition

Purpose: This study uses the kayak dynamometer to simulate the three stages of the start of the oars, the stroke on the way and the final sprint during the competition. Use portable exercise cardiopulmonary function tester to measure HR, V`E, V`O

/Kg, RER and other data during exercise, Analyze the gas metabolism changes and correlations of excellent kayakers during these three stages, in order to intuitively understand the characteristics of kayaking, with a view to realizing special function evaluation and selection of athletes for canoeists, it provides experimental basis and data support for scientific training monitoring.Methods: Using literature method, experiment method and mathematical statistics method to conduct a comprehensive research on the gas metabolism characteristics of simulated canoeists in the three stages of exercise.Research result: There are significant differences in the heart rate of the three stages of exercise patterns (P<0.01). There are statistical differences in the indicators in the three phases of the test. There is a correlation between the gas metabolism indicators in the three-stage test .
