  1. Kayaking:Eskimo Rolls Alyssa Van Patten

  2. 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

  3. 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

  4. Recovery Phase • Trunk leaning backwards • Bring head up • Bring trunk forwards • Bring paddles back up to parallel • Balance self

  5. Biomechanics • Acrobatics • Rotating about an axis through water • Balance • Getting the COM over the BOS and keeping the kayak upright

  6. 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

  7. 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

  8. Other Factors • Timing of Segments • Hip snap trunk  upper body  head • Fear of being upside down • Vision

  11. Observation

  12. Observation • View from front and 45 degree angle • High-speed, water proof camera • Listen • Environmental factors • Weather • Water conditions • Type of kayak • Gear

  13. 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

  14. 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
