We evaluated kayak paddling performance using a triaxial accelerometer that was fitted on the lower back of 6 collegiate athletes.First, during stepwise incremental paddling exercise on a simulated machine, the total impulse (the square root of summed body-acceleration in each of 3 directions) was highly correlated with oxygen uptake and work output. These results suggest that the total impulse is related to power output and oxygen uptake during kayak paddling exercise. Second, during the ramp incremental paddling exercise on a kayak boat, there was an inflection point in the relationship between boat speed and total impulse. The propulsive drag of a boat in water increases as the square of average speed. The inflection point may have reflected the increase in amount of movement that occurred to produce the energy required by the increase in propulsive drag as boat speed increased.The triaxial body accelerometer can be used to evaluate paddling exercise in kayak on water.

We evaluated kayak paddling performance using a triaxial accelerometer that was fitted on the lower back of 6 collegiate athletes.First, during stepwise incremental paddling exercise on a simulated machine, the total impulse (the square root of summed body-acceleration in each of 3 directions) was highly correlated with oxygen uptake and work output.这些结果表明，总冲动与皮划艇划桨运动过程中的功率输出和摄入有关。其次，在皮划艇船上的坡道逐渐划桨运动中，船速与完全冲动之间的关系有一个拐点。随着平均速度的平方，船在水中的推进拖动会增加。拐点可能反映了随着船速的增加而导致推进阻力增加所需的运动量的增加。三轴体加速度计可用于评估在水上划皮艇上的划桨运动。
