The purpose of this study was to investigate the relationship between sensory systems, motor skills, and physical activity of male children.  44 male children (age= 9.59 ± 0.75 years) whose age is between 9-11 years were involved in this study. Height and weight were measured as anthropometric measurements. Sensory systems were assessed by using the modified Clinical Test of Sensory Interaction and Balance (m-CTSIB) on BIODEX Biosway Portable Balance System through four test conditions (Eyes open - Firm Surface, Eyes Closed - Firm Surface, Eyes open - Dynamic Surface, Eyes Closed - Dynamic Surface). 30s test and 10s rest were used as test protocol for all test conditions. Plank test, 505 change of direction test, 20m sprint test, ankle dorsiflexion Range of Motion (ROM) test was used to assess motor skills. Physical activity was measured by using GT3X-BT Actigraph accelerometer. At the end of this observation, Moderate to Vigorous Physical Activities (MVPA) was determined. Pearson correlation coefficient (r) was used to determine the degree of correlation between the parameters when parametric assumptions were satisfied, otherwise Spearman rank correlation coefficient (rho) was used. Statistical analysis was performed with SPSS 23.0 statistic software package.  As findings, only visual sensory system correlates significantly with 505 change of direction test (rho=0,394; p<0,05). As conclusion, except visual sensory system no significant correlations were observed with Physical activity and bio-motor abilities.
