Improving paddling efficiency through raising sitting height in female white water kayakers.

Broomfield SA, Lauder M - J Sports Sci (2015)

Bottom Line: The efficiency of all participants improved on the seat condition for ≥4 of the measures, with three participants showing improvement for ≥6 of the measures.The stern snaking measure had the highest value of significance (P = 0.1455) and showed an average of 11.98% reduction in movement between no seat and seat conditions.The results indicate that improvements were seen although these were individualistic.

ABSTRACT
The study compared female white water paddlers over two conditions: with seat raise and with no seat raise. The aim was to determine whether raising the sitting height would improve paddling efficiency. Sitting height of each participant was recorded in order to calculate the seat raise height required and three-dimensional kinematic data was collected for six participants over both conditions. Twelve measures of efficiency were utilised. The efficiency of all participants improved on the seat condition for ≥4 of the measures, with three participants showing improvement for ≥6 of the measures. The stern snaking measure had the highest value of significance (P = 0.1455) and showed an average of 11.98% reduction in movement between no seat and seat conditions. The results indicate that improvements were seen although these were individualistic. Therefore it can be concluded that it is worth experimenting with a seat raise for a female kayaker who is lacking efficiency, noting, however, that improvements might depend on anthropometrics and the seat height selected, and therefore could elicit differing results.

Difference between no seat and seat conditions for stern snaking for each participant. A positive result denotes a decrease in stern snaking with the raised seat condition. A negative result denotes a decrease in stern snaking for the no seat condition.

Figure 0001: Difference between no seat and seat conditions for stern snaking for each participant. A positive result denotes a decrease in stern snaking with the raised seat condition. A negative result denotes a decrease in stern snaking for the no seat condition.

Mentions: There was no statistically significant (P < .05) difference between the conditions for any of the measures (Table II). However, the result with the highest value of significance (P = 0.146 one-tailed) was for the snaking stern pair where there was a decrease in stern snaking from the no seat condition (M = 0.1788, s = 0.053) to the seat condition (M = 0.1574, s = 0.044). The means for each of the no seat and seat conditions (0.1788 and 0.1574, respectively) can be used to calculate an average of 11.98% reduction in movement at the stern for the seat condition. The largest difference between the two conditions was seen in participant 4 with a positive result (Figure 1). These results indicate that the seat raise reduced the amount of snaking at the stern on average for the participants. However, two participants (participants 1 and 5) showed a negative result, which explained the lack of a significant result in this measure. These two participants (1 and 5) that showed a decrease in efficiency in the seat raise condition were also the lightest paddlers in the sample (Table I).Table II.
