| ABSTRACT | |||
| This study aimed to identify the effect of different stroke rates
on various kinematic parameters during 1000 m outrigger canoeing. Sixteen,
experienced female outrigger canoeists completed three 1000 m outrigger
ergometer time trials, one trial each using a self-selected, a Hawaiian
(< 55 strokes·min-1) and a Tahitian (> 65
strokes·min-1) stroke rate. Stroke rate, stroke length, stroke
time, proportion of time spent in propulsion and recovery, torso flexion
angle and 'twist' were measured and compared with repeated measures ANOVAs.
Stroke rate, stroke length and stroke time were significantly different
across all interventions (p < 0.05) despite no difference in the percentage
of time spent in the propulsive and recovery phases of the stroke. Stroke
length and stroke time were negatively correlated to stroke rate for all
interventions (r = -0.79 and -0.99, respectively). Female outrigger canoeists
maintain consistent stroke kinematics throughout a 1000 m time trial, most
likely as a learned skill to maximize crew paddling synchrony when paddling
on-water. While the Hawaiian stroke rate resulted in the greatest trunk
flexion movement and 'twist' action, this potential increased back injury
risk may be offset by the slow stroke rate and long stroke length and hence
slow rate of force development.
Key words: Stroke rate, paddling, torso flexion, female athletes. |
