Abstract

An experimental analysis of the factors involved in the two kinds of equilibrium and of the interrelationship of their components yielded the following major results: The dynamic component of equilibration is unrelated to the static component. There is practically no correlation between balancing skill on the stabilometer and ability manually to maintain orientation of a rotation chair in continuous displacement. Weight is of relatively greater importance than height in dynamic stabilometer performance, and distance from the center of gravity to the foot base line shows high correlation with standing height. When weight is controlled, there is a small sex difference in favor of women's performance on the stabilometer. Both dynamic and static equilibrium show greatly superior performance when visual cues operate. While mild exercise increases body sway significantly as a result of increased respiration and therefore of head movements, it shows little effect on dynamic stabilometer performance. A correlation of .50 between eye-manual co-ordination and balancing skill is believed to show presence of a steadiness factor in the two performances.
