A visual enhancement training program utilizing stroboscopic lighting was evaluated. Pre-training, training, and post-training sessions were conducted and analyzed to inspect the effects of stroboscopic lighting on catching tennis balls being propelled from a tennis ball machine. The ball catching ability of forty-one high school baseball athletes was assessed using a qualitative scale and a quantitative scale in both pre-training and post-training sessions. The subjects were matched by abilities following the pre-training session into a control group or an experimental group, based on their qualitative score. Contrary to our hypothesis, it was concluded that those athletes in the control group (no stroboscopic training) demonstrated a significantly greater improvement than the experimental group (stroboscopic training), based on the difference between their pre-training and post-training scores. Our data revealed three factors that appcar to be important in ball-catching: stereoacuity, cross dominance, and the level of competition. Future questions as to optimal training conditions under stroboscopic lighting need to be addressed.
