The effects of ski goggles' induced field and tint on stability and balance

1 December 2001

Abstract

Subjects (n=30) were exposed to four goggle-induced visual conditions while attempting to balance on a Lafayette stabilometer. Subject participated in eight, one-minute trials that included two random exposures to each of the four testing conditions: no goggle, clear goggle, tinted goggle and reduced field. Both the duration and frequency of the stabilometer's oscillation between a stable and non-stable position was measured. Only the reduced field goggle condition statistically impaired the subjects' ability to maintain their balance on the stabilometer. Despite randomization and two practice trials before testing, subjects experienced a significant learning effect between their first and second exposure to each testing condition.
