A recent study conducted by researchers from New York University (NYU) has shown that mastery of the Hula-Hoop depends significantly on body shape, not just on the applied technique. The results, published as part of a broader study in the physics of motion, could create new perspectives in robotics and energy.
The research team conducted experiments using specially developed robots to execute movements with the Hula-Hoop. They tested the influence of various body shapes and motion profiles on the productivity of the robots. Experiments showed that robots with bodies combining broad "hips" and narrow "waists" were the most effective in maintaining the spinning of the hoop, while robots with shapes resembling an electric lamp could not sustain the hoop's rotation.
Professor of mathematics Liv Restrov from New York University emphasized: "We focused on understanding different body movements and shapes that help maintain the hoop's spinning state and what physical limitations are associated with this." The study indicated that body shape was a key factor in the success of Hula-Hoop execution, while the sheer continuous arrangement of robots or the motion of the spin had no significant influence.
Restrov explained that "the diversity of body shapes, sizes, and waist shapes explains why some people can master the Hula-Hoop while others struggle."
Researchers added that speed began to play a decisive role, as slow spinning or gentle spinning often led to the hoop's dropping. Also, from a varied perspective, the research encompasses broader applications. The team developed mathematical models explaining movements that can be used for improving the productivity of robots, allowing them to move through motion rather than keeping still.
These results can enhance energy systems, improving the use of vibrations. Restrov concluded: "We were surprised by the complexity of the physics behind such a simple and popular action, like Hula-Hoop. Through the progression of research, we realized that this mathematics and physics can contribute to future innovations."
