Objectives: The goal of the present study was to compare the role of vision on static postural stability between athletes and nonathletes.

Methods: Participants included two groups of 25 persons, men Karatekas who were selected in Isfahan (age 20.6±2.8 years, 66.24±10.34 kg of weight, height 1.76±0.07 m) and healthy young men in Isfahan (age 21.6±2.33 years, 66.8±11.34 kg of weight, height 1.74±0.08 m). The sampling was conducted on the basis of nonprobability sampling method. All participants performed the static balance test on the force plate. Postural stability was measured and assessed during 35 seconds in a state of constant standing with paired feet in the center of the force plate in the two positions of eyes open and closed (3 trials in each positions) with random sequences. The rest between trials was 25 seconds. Parameters of mean velosity, standard deviation of velosity and standard deviation of amplitude in both anterior-posterior and medio-lateral plans from the center of foot pressure were recorded by the device. Two-way ANOVA was used for data analysis.

Results: The test results showed that the interaction between vision and group did not exist. Closing the eyes led to a significant increase in postural sway in all parameters. Two parameters of mean velocity and standard deviation of velosity in medio-lateral plan were significantly greater in athletes than nonathletes.

Discussion: The findings can be considered for the design of exercises in karate and rehabilitation after sports injuries.
