The purpose of this study was to compare centre of gravity deviance to difference surfaces for adolescent male elite gymnasts and wrestlers with non-athletes. Subjects were asked to maintain balance in four standing postures: standing with open eyes and close eyes, standing with right leg and left leg. Quadriceps muscle and posterior muscle leg strength was collected with a dynamometer. There was difference in static balance in standing one leg (left) in end tasks. There were no significant differences in static balance in other tasks. Posterior muscle leg strength in elite athletes was significantly greater than non- athlete. There was no significant difference in quadriceps muscle. Gymnasts can decrease anterior-posterior and medial-lateral deviance on one leg to use vision feedback and proprioception.
