Abstract

A study was conducted to investigate the characteristics of kinetic vision in women's table tennis players. There are kinetic visual acuity and dynamic visual acuity in kinetic vision. In the present experiment, sports vision of women's table tennis players were measured; member of society women's table tennis players (S group: aged 24.7±1.3yrs),university women's table tennis players(U group: aged 19.5±1.1yrs),high school women's table tennis players (H group: aged 16.3±0.8yrs),junior high school women's table tennis players(JH group: aged 13.6±0.8yrs),elementary school women's table tennis players(ES group: aged 11.1±1.0yrs), and Kyoto sangyo university student women's non-athletes (NA group: aged 18.7±0.5yrs). Then players 7 numbers in S group,22 numbers in U group,32 numbers in H group,19 numbers in JH group,49 numbers in ES group and 10 numbers in NA groups(their static visual acuity>1.0) were selected as subjects. Static visual acuity, kinetic visual acuity, dynamic visual acuity, contrast sensitivity, ocular motor skill, depth perception, visual reaction time and eye-hand coordination of them were measured. Physical characteristics and experience of training of table tennis were investigated using questionnaire. Mean values of kinetic visual acuity were no significantly among all groups, dynamic visual acuity in U groups were significantly higher than H,ES groups. Kinetic visual acuity and dynamic visual acuity showed difference about contribution rates for measurement item. Static visual acuity, contrast sensitivity and eye-hand coordination showed greater contribution rates for kinetic visual acuity. Visual reaction time, ocular motor skill and eye-hand coordination showed greater contribution rates for dynamic visual acuity. Significant correlations between static visual acuity, contrast sensitivity and experience of training were not found, but significant positive correlations between visual reaction time, ocular motor skill and experience of training were found and significant negative correlation between eye-hand coordination and experience of training was found. These results suggest that the improvement of kinetic visual acuity hold the best static visual acuity, the improvement of dynamic visual acuity are caused by heavier training and these are the important for the level up game ability.
