Abstract

Background: the effect of sports visual training on perceptional and kinetic performance has been long studied by scholars among subjects with vision impairment, with main variables considered as the degree of impairment and individual's age. Most of recent studies have directed the acute impairments as well as children groups. Considering the large population of those adults suffering from vision acuity impairment, this study attempts to investigate the same group of subjects. Purpose: the main purpose of this study has been to investigate the effects of sports visual training on eye-hand coordination and perception of depth among adults with impaired vision acuity. Materials and Method: the method used to conduct this study was quasi-experimental through the use of pre-test and post-test. The sample has been selected through availability sampling method from the population of 21-27 years students in University of Tehran with average age pf 24.6+2.8 who had impaired vision (nearsighted). A total of nine subjects have been selected. At first, eye-hand coordination test and perception of depth has been conducted. Then, the subjects took part in 18-20 sports training sessions and at the end of the sessions, depth perception test has been conducted. Results: the results of correlated T-test between pre and posttest showed that the visual training protocol significantly impacted the eye-hand coordination, in terms of the number of error factors as well as maintaining the error status (p=0.002, p=0.012); however, there wasn’t any significant difference in terms of timing (p=0.130). Besides, the implementation of sports visual training protocol significantly impacted depth perception as well (p=0.001). Conclusion: the results of present study can be used to improve eye-hand   coordination among adult subjects with impaired visual acuity to improve their perception of depth and eye-hand coordination.
