PUT DOWN THAT HULA HOOP, Pop, unless you want a painful reminder that your lumbo-sacral joint went into lazy adult retirement years ago.
For the benefit of those puzzled parents who wonder what mysterious power is employed to keep a hoop gaily spinning around juvenile hips, Scope Weekly — a medical newspaper published for doctors by the Upjohn Co. — took hula hooping in for a clinical examination. Here’s the verdict:
Hula hooping is an excellent form of exercise for youngsters, but can cause disastrous consequences in an adult. This is because it involves muscles that the average adult doesn’t ordinarily 086-
Figure A shows how a child keeps a hoop in rotary motion by rapid reciprocating movement of the pelvis. All flexors and extensors of the vertebral column, the pelvis and the thigh are used (arrows). Figure B shows how rapid tilting of the pelvis is synchronized with sagittal flexion-extension. Muscle groups act singly and then in concert to produce gyratory motion. The muscles involved (shown by arrows) are iliacus, psoas, quadratus, lumborum and erector spinae.
