The purpose of this study was to determine the effects of 16 weeks weight training on sensory organization function in ski players. Computerized dynamic posturography (Equi-Test) was used to test sensory organization. Equi-Test facilitated of the role of somatosensory, visual and vestibular system in the maintenance of postural balance. Subject were assigned to healthy univ control group (n=14), K-university ski player(n=14). The exercise group were trained for 2 hour a day, three times per week, during 16 weeks. We analyzed mean difference of observed variables by two-way repeated ANOVA between the pre and post test. The result were as the following : First, the effect was significant developed the condition C2, C3, C4, C6 after 16 weeks weight training. Second, the effect was significant developed the condition C1, C4, C5, C6 on balance strategy. The result of this reveal that 16 weeks weight training developed on postural balance and strategy.
