The Aim of the this research is to compare reaction time of students non-athletes in modified Agility test for Table Tennis after one semester course of Table Tennis. Thirty three men participated in our study (average 21.8 years, 178.2 cm, 77.1 kg), one group of eighteen students in autumn, another group of fifteen students in spring. We used modified Agility test for Table Tennis using Fitro Agility Check at the beginning of the semester (pre-test) and at the end of the semester (post-test) and compared dates. We have not proved statistically significant improvement of reaction time after one semester course of Table Tennis, although most of the students had improved. Average reaction time was 2.33 % better after one semester (1.76% when using hands, 2.85 % when using feet). We believe that course of Table Tennis is good choice for students, if they want to improve their reaction time, even we can not to prove it statistically.
