Abstract
The link between internal and external forces in rowing and the related kinematics causing stroke length, stroke frequency and boat velocity is presently ambiguous. This study examined these biomechanical parameters using two diverse rowing techniques: Rosenberg and Pose. Ten female novice rowers participated in a pre-and post-test 1 km time trial using a Concept 2 ergometer fitted with load cells at the handle/foot stretchers. Pose rowing was significantly different from Rosenberg rowing in increased stroke frequency per minute (mean ± S. D. 32 ± 1: 37 ± 4) and decreased stroke length (m) (1.3 ± 0.1: 1.1 ± 0.1). Oar handle impulse (N. s) was significantly less in the Pose rowers (266 ± 24: 222 ± 26) while power (W) remained similar (223 ± 26: 222 ± 26). SIMI Motion recorded two-dimensional kinematics. Significantly less trunk extension (°) (-29 ± 1.0: -14 ± 0.5) at the end of the drive phase in Pose rowing may explain the stroke length and stroke frequency significant differences between the two techniques possibly owing to the 18.3% shorter drive time. Practical application centred on the transfer of body weight from the foot stretchers, oar handle and seat in reference to the influence of muscle activity.
