The purpose of this study was to determine the relationship between visual tracking speed (VTS) and reaction time (RT) on basketball specific measures of performance. Twelve professional basketball players were tested prior to the 2012-2013 season. VTS was obtained from one core session (20 Trials) of the multiple object tracking test, while RT was measured via fixed- and variable-region choice-reaction tests, using a light-based testing device. Performance in VTS and RT, were compared to basketball specific measures of performance (assists [AST]; turnovers [TO]; assist-to-turnover ratio [AST/TO]; steals [STL]) during the regular basketball season. All performance measures were reported per 100 min played. Performance differences between backcourt (guards; n=5) and frontcourt (forwards/centers; n=7) positions were also examined. Relationships were most likely present between VTS and AST (r=0.78; p<0.003), STL (r=0.77; p<0.003), and AST/TO (r=0.78; p<0.003), while a likely relationship was also observed with TO (r=0.49; p<0.109). RT was not related to any of the basketball specific performance measures. Back-court players were most likely to outperform frontcourt players in AST and very likely to do so for VTS, TO, and AST/TO. In conclusion, VTS appears to be related to a basketball player's ability to see and respond to various stimuli on the basketball court that results in more positive plays as reflected by greater number of assists and steals, and lower turnovers.
