카약 스프린트 종목에서 패들 그립너비가 카약 전방 스트로크 동작과 보트 안정성에 미치는 영향 = Effect of Paddle Grip Width on Movement of Forward Stroke and Stability of Boat during Kayak Sprinting

다국어 초록 (Multilingual Abstract)

The purpose of this study was to identify the contribution that paddle grip width has to successful performance during the forward stroke movement pattern, and boat stability in kayak sprinting. Eight male elite kayak athletes participated in this study. Kayak athletes performed kayak sprinting with three grip width conditions (preferred grip(PGW); narrow grip(NG); wide grip(WG)) while stroke frequency, paddling distance, knee joint ROM and angular velocity, trunk rotation ROM, boat stability, integrated EMG(rectus femoris: RF, biceps femoris:BF) were measured and analyzed. The results showed that kayak performance with preferred grip width condition is better than others. For the wide grip width, rotation of trunk is larger and iEMG of Biceps femoris. However, the boat stability was affected negatively. There were no overall significant differences, but some conditions were significant differences in Bonferroni’s post hoc test. Wide grip width helps make more rotation of trunk and more iEMG value of BF, but no good performance because of large ROM of boat roll angle. Large ROM of boat roll can be was a main factor reducing kayak velocity. The improvement of paddling technique to minimize ROM of rolling angle is needed for kayak athletes to use a wide grip width.
