The aim of this study is to investigate whether the biomotor capacities of boys doing table tennis trainings are affected. A total of 40 students, as randomly selected 20 test groups and 20 control groups at an age range of 10-12 participated in the research. Statistical analysis of data was performed using Statistic Package for Social Science (SPSS) 20.0 statistical package program. Mann Whitney "U" Test was used in comparison of two variable groups, and the result being p<0.05 was considered significant when examined statistically. In pre-test and final-test comparisons of the subjects, it was detected that the statistical differences between flexibility, vertical jump, standing long jump, 30 m sprint, anaerobic strength, maximal oxygen capacity (MaxVO2) right and left hand grip strength, visual and audio reaction times, resting heart rate, and forced expiration volume (FEV) and FEV1 measurements were significant in favor of the test group (p <0.05), while there was no statistically significant differences between the two groups in height, body weight, body fat percentage, body mass index, systolic and diastolic blood pressure, and vital capacity (VC) and forced vital capacity (FVC) values (p >0.05). At the end of this study, it was observed that table tennis trainings provided positive contributions to biomotor capacities in boys of the group aged 10-12.
