Kinetics of hula hooping: An inverse dynamics analysis

This paper involved a biomechanical analysis of lower limb joint coordination during hula hooping. A lower extremity inverse dynamics model that incorporated kinematic input and force platform data was developed to compute the angular velocities, moments about and powers produced at the lower extremity joints. The abductor moments and powers were discovered to be paramount in maintaining hoop oscillations, as demonstrated consistently in the three study participants. However, hula hooping was demonstrated to be variable in terms of the involvement of flexor and extensor moments and powers of the ankle, knee and hip joints, resulting in the adoption of varying strategies by each of the three participants.
