Stereopsis and Response Times between Collegiate Table Tennis Athletes and Non-Athletes.

Table tennis athletes and non-athletes potentially differ in stereopsis and eye-hand response times (RT), but whether stereopsis correlates with response time has scarcely been discussed. We aimed to compare stereopsis and RT between collegiate table tennis athletes and non-athletes and to examine the correlation between stereopsis and RT. From December 2016 to October 2019, table tennis athletes ( = 80) and non-athletes ( = 56) were recruited. Stereopsis was measured in four modes (A25, A50, R25, R50: approaching and receding directions at 25 mm/s or 50 mm/s). RT was measured with simple and choice tasks at zero, shoulder, and random distance. For stereopsis, the judged deviations were smaller during the approaching phases. Men had smaller A25 than women ( =0.012), whereas table tennis athletes showed smaller R25 and A50 than non-athletes ( = 0.03, 0.01, respectively). RT increased from simple to choice conditions and from zero to random, followed by shoulder distance. Men were significantly faster than women in choice tasks ( < 0.01). Table tennis athletes performed better in RT than the non-athletes ( < 0.05). No correlation was observed between stereopsis and RT ( = -0.01 to 0.12). In conclusion, athletes from table tennis sports showed better stereopsis and RT than non-athletes. Men had better stereopsis and RT than women. There was no correlation between stereopsis and RT.
