Study Reveals Body Shape Key to Hula Hooping Success

Mathematicians uncover the physics behind hula hooping, identifying the role of body geometry in maintaining a stable spin.

Researchers at NYU used robotic models and mathematical analysis to explore the mechanics of hula hooping, marking the first comprehensive study of its physics.
The study found that while anyone can initiate a hula hoop spin, maintaining the motion requires specific body traits such as sloping 'hips' and a curvy 'waist.'
Miniature experiments with 3D-printed robotic shapes revealed that hourglass-like forms are most effective at sustaining a hoop's spin against gravity.
The findings highlight broader applications, including advancements in energy harvesting, robotics, and industrial machinery design.
The research, published in the Proceedings of the National Academy of Sciences, was supported by the National Science Foundation.
