“…The force on the paddle was evaluated for kayaking [11][12][13][14] and canoeing [15] but was not linked to the kinematics directly. On the contrary, Delgado [16] proposed a model for the evolution of the velocity of a kayak without experimental measurements of the force and the velocity.…”

The propulsion force of a kayaker can be measured thanks to sensors placed on the paddle. This article aims at linking this force to the evolution of the velocity of the boat. A general model is proposed to describe the motion of a K1 kayak. To validate the model and evaluate the relevant physics parameters, three on-water kayaking trials are proposed: a pure deceleration, a standing start, and 10 × 50 m with two athletes at the national level. These trials were performed with a force sensor on the paddle and video recording. We used the deceleration to evaluate the drag of the boat. Then the standing start showed that there was an active drag coefficient while kayaking. Finally, the 10 × 50 m exhibited a power law of one-third between the velocity and the stroke rate. The acceleration during the standing start together with the relationship between the velocity and stroke rate were well captured theoretically. This approach enabled us to evaluate the important parameters to describe a kayak race: the drag of the boat, an active drag coefficient, the mean propulsive force, and a propulsive length. It can be used to characterize athletes and monitor their performances.

“…Even if GPS and IMU systems are small and easy devices, they must be worn by the athlete or subject to obtain measurements. In this context, these modern devices have been employed to produce mathematical models able to describe the characteristics of kayak stroke in terms of periodicity and average strength, and the effects of these on stroke frequency [5]. Similarly, in [6], traditional measurement procedures were exploited to define statistical prediction methods such as linear recommendation scores, logistic regression, discriminant analysis, and a neural network for identifying talents in tennis.…”
