Download - Kayaking: Eskimo Rolls
Initial/ Prep Phase
• Rotate hips to the left• Lean trunk forward and to
the left• Bring paddle to the left side,
parallel to the kayak• Right hand paddle is parallel
to the water, not perpendicular
• “Kiss the deck”= lean forward, head down
Sweep Phase• Back paddle close to the
boat• Sweep the front paddle
out, bending the elbow• Relax upper body• Snap left hip into ext• Keep head down• Timing of segments: hips
trunk shoulders head• Eyes on hands
Recovery Phase
• Trunk leaning backwards• Bring head up• Bring trunk forwards• Bring paddles back up to parallel• Balance self
Biomechanics
• Acrobatics– Rotating about an axis
through water• Balance– Getting the COM over
the BOS and keeping the kayak upright
Acrobatic
• Rotating about an axis– Create torque to force self off center and start
rotating– Small moment of inertia- get as close to kayak as
possible- less resistance to stopping– Pushing hips up (hip snap) and leaving behind the
upper body to counterbalance
Balance
• During hip snap– COM in the center of the boat near the hips– Hips snap up, COM will quickly get in line with BOS– If upper body goes first, COM is too low to bring
the kayak up• Recovery Phase– Bringing the paddle parallel to the water and the
trunk upright will stabilize and bring COM in the center of BOS
Other Factors
• Timing of Segments – Hip snap trunk upper body head
• Fear of being upside down• Vision

Observation• View from front and 45 degree angle• High-speed, water proof camera• Listen• Environmental factors– Weather– Water conditions– Type of kayak– Gear
Evaluation• First watch overall movement to make sure
they are getting up• Break it into the three parts• Would watch the sweep phase first to make
sure they got the hip snap above everything else
• Then watch the other phases
Implement Intervention
• #1 = get over fear of being upside down in water• #2 = fix the biggest problem in their technique– Usually using upper body instead of hip snap
• #3 = Practice each phase separately– Getting into roll tuck position– Practicing hip snap and sweep– Moving hips back and forth in kayak for balance
(recovery phase)• #4 = Fix minor technical problems after that
