A biomechanical analysis of the Olympic-style flatwater kayak stroke.

摘要: ABSTRACT MANN, RALPH V. and JAY T. KEARNEY. A biomechanical analysis of the Olympic-style flatwater kayak stroke. Med. Sci. Sports Exercise. Vol. 12, No. 3, pp. 183–188, 1980. To investigate biomechanics kayaking, technique nine Olympic caliber K-1 paddlers was analyzed using cinematographic computer procedures. Results indicated that, during paddle-water contact, horizontal arm action one push-then-pull with push coming from farthest water (thrust segments) followed by pull ann closest to (draw segments). During this action, center paddle rotation shifted up shaft as stroke progressed, which increased time in power phase The movement patterns individual segments that accomplished an integrated thrust wrist elbow, minimal shoulder involvement. Subsequently, draw wrist, shoulder, well shoulder. latter stages since performers were unable generate additional useful power, rapidly withdrawn avoid-dragging. Subject stability frontal plane maintained shifting body mass toward contact side at entry away it exit. This opposed vertical forces produced a by-product final outcome maintenance gravity velocity while boat oscillated under performer.
