Introduction: Outrigger sprint racing involves common paddling techniques such as the Hawaiian (H) and Tahitian (T) styles that are characterised by stroke rates as low as 42 strokes∙min-1 or as high as 70 strokes∙min-1, respectively. Additionally, Australian outrigger canoeists adopt a stroke rate in between these extreme styles (55-65 strokes∙min-1). The aim of the study was to determine which outrigger style and stroke rate resulted in the fastest 1000m performance while moderating physiological demand.
Methods: Following ethics approval, seventeen outrigger canoeists provided informed consent and completed a 1000m outrigger ergometer time trial using their self-selected (SS), H (≤ 55 strokes∙min-1) and T (≥ 65 strokes∙min-1) stroke rates. Performance time and average and/or peak heart rate (HR), oxygen consumption (VO2), ventilation (VE), respiratory rate (RR), blood lactate concentration (LA) and rating of perceived exertion (RPE) were recorded for all trials. Repeated measures ANOVAs and Tukey HSD post-hoc tests were used to compare data across trials and 250m splits (p<0.05).
Results: Stroke rates were significantly different between outrigger styles (SS 61±6, H 54±1, T 70±4 strokes∙min-1) with the SS trial resulting in a significantly slower time than the H and T trials (371±38 vs. 358±30 and 357±28 s). The H trial resulted in a significantly lower average VO2 and RR, and significantly lower peak HR, VE, RR, LA and RPE than the SS and T trials.
Conclusions: Outrigger canoeists should use a stroke rate of ≤55 strokes∙min-1 to elicit a fast 1000m performance with less physiological demand compared to faster stroke rates.
