皮划艇运动是周期性的划浆运动。在皮划艇运动的技术环节中，拉浆是划浆的关键，拉浆实际上就是使身体的力量传递至浆叶作用于水，产生反作用力，以克服水和空气等阻力，使船体前进。划船的技术可解释为用力的效果即通过拉浆，使全部的力量由浆叶最有效地作用于水，周而复始。 Kayaking is a periodic stroke. In the technical aspect of canoeing, pulling the pulp is the key to drawing. In fact, pulling the pulp is to transfer the body’s power to the pulp to act on the water to generate reaction force to overcome the resistance such as water and air to advance the hull . The boating technique can be interpreted as a forceful effect by pulling the pulp, so that the full force is exerted on the water most efficiently by the paddles, going back and forth.
