Differences in spinopelvic kinematics in sweep and scull ergometer rowing.

Area of Science:

• Biomechanics
• Sports Medicine
• Ergonomics

Background:

• Sweep rowing may increase risk of low back pain (LBP).
• Spinopelvic kinematics in sweep vs. scull rowing are not well understood.
• Investigating kinematic differences can inform LBP prevention strategies.

Purpose of the Study:

• To compare spinopelvic kinematics between sweep and scull rowing in elite athletes.
• To identify potential biomechanical factors contributing to LBP in sweep rowing.

Main Methods:

• Repeated measures study design.
• Ten high-level rowers participated.
• Measured kinematics of pelvis and spine (lower lumbar, upper lumbar, lower thoracic) during ergometer rowing.

Main Results:

• Sweep rowing exhibited significantly greater lateral bending (upper lumbar/lower thoracic) and axial rotation (pelvis) at the catch.
• Both rowing styles showed end-range lower lumbar flexion at catch/early drive.
• No significant differences in lower lumbar lateral bend or axial rotation were observed between sweep and scull rowing.

Conclusions:

• Distinct spinopelvic kinematic patterns exist between sweep and scull rowing.
• The lack of lower lumbar rotation/bending in sweep rowing may indicate protective adaptations in experienced rowers.
• Further research is warranted to explore these adaptive mechanisms and their role in LBP prevention.
