Objectives: This study aimed to determine the effect of light stimulation exercises on attention focus (visual auditory), lactic acid, and skilled hand speed of wheelchair basketball players. Methods: We used the experimental method on 24 wheelchair players who were divided into two groups, the first experimental (N = 12; age, 20.58 ± 0.90 years; training, 4.71 ± 0.62 years). The other was a control (N = 12; age, 20.67 ± 0.62 years; training, 4.77 ± 0.58 years). Lactic acid was measured by Lactate Pro 2 Blood Lactate Meter, attention focus (visual-auditory) was measured using the Li Lafayette Instrument 63035, and skilled hand speed was assessed with the Modified Y-Test for Measuring Skill Hand Speed (Three-Zone Shooting). The proposed program was applied over 10 weeks at a rate of four weekly training units. Results: Results showed improvement in the level of attention focus (R.H; LH) at a rate of (p = 0.001) and a decrease in the level of lactic acid BE, AE (1,3,5 Min) with a value of P = 0.001 (P<0.05). The modified three-zone shooting T-test showed an improvement (p = 0.001) in favor of post-measurements of the variables under study for the experimental group of wheelchair basketball players. The experimental group was superior to the control group, as it showed an improvement in the level of attention focus (R.H; LH) at a rate of (p = 0.000) and a decrease in the level of lactic acid BE with a value of p = 0.002, AE (1,3,5 Min)P=0.000. The modified three-zone correction T-test showed improvement (p = 0.000) for wheelchair basketball players. Conclusions: We suggested that the light stimulus can be used in a more appropriate and effective way in training of wheelchair basketball players. This primarily applies to decision-making which is often more challenging during specific sports performance.
