Paddling time parameters and paddling efficiency with the increase in stroke rate in kayaking

Beatriz B. Gomes et al.

Summary: The paddling stroke rate is crucial for flat water kayak performance. This study analyzed how kayak paddlers change the duration of water and aerial phases with increasing stroke rate. The results showed that reaching higher stroke rates is important for increasing kayak velocity. The duration of water and aerial phases negatively correlated with stroke rate, but the relationship was linear for the former and curvilinear for the latter. The study suggests that at high stroke rates, reducing the duration of the water phase is more productive for further increasing the stroke rate.

A kinematic comparison of on-ergometer and on-water kayaking

Kent K. Klitgaard et al.

Summary: This study aimed to compare the kinematic profile between on-water and on-ergometer kayaking during maximal paddling. The results showed differences in elbow, shoulder, and knee kinematics between on-ergometer and on-water performance for elite female kayak athletes. Additionally, an increased range of motion in lateral bending in the thoracolumbar joint was observed during on-ergometer paddling.

Pacing and stroke kinematics in 200-m kayak racing

Craig W. Pickett et al.

Summary: The study indicates that faster rates of acceleration and the ability to exhibit greater stroke lengths at relatively high stroke rates are determinants of 200-m kayak race performance.

One-Dimensional Mathematical Model for Kayak Propulsion

Diego Delgado et al.

Summary: A one-dimensional mathematical model is used to describe the displacement of a sprint kayak, with the use of Fourier series to separate the equation into two parts for solving realistic cases effectively. This approach allows for fast estimations using a quadrature rule for the asymptotic part and comparing results with existing literature, proposing a general mathematical method for understanding key strategies in kayak racing.

Pacing strategies and relationships between speed and stroke parameters for elite sprint kayakers in single boats

Joshua A. Goreham et al.

Summary: The study found that elite single-boat sprint kayakers adopt different pacing strategies based on the race distance during major international competitions. The relationships between stroke parameters and speed vary depending on athlete sex and the race distance.
