On the other hand, as for the investigation of the pre and post-test interactions of experiment and control group, When pre and post-test interactions of experimental and control groups were examined, there was no significant difference in visual attention and dynamic balance development, but in eye-hand coordination test, improvement in experimental group was found to be higher than in control group. Conclusions: The findings of the study in which exercising brain applied to boxers for 8 weeks showed that there was no significant difference between dynamic balance and visual attention development values, but there was a significant difference between control and experimental groups, eye-hand coordination development values.
