INTRODUCTION: Studies and debates in the field of motor development reveal that sport and physical activity develop and improve motor skills. These studies seek to understand the changes that occur with movement, which becomes more complex as it develops through physical activity. OBJECTIVE: To compare the level of physical activity and motor coordination of students in different maturational stages and to relate the level of physical activity with the motor coordination of young people. METHODS: Descriptive research with cross section. The study included 46 male individuals, aged between 10 and 14 years. The Baecke Habitual Physical Activity questionnaire was applied; the maturity stage was verified through the Pubertal Maturation Prediction Equation; body composition was assessed using the Guedes protocol for children and adolescents; Finally, the coordinating performance was rated using the Korperkoordinationstest fur Kinder (KTK) test battery. RESULTS: There were significant differences for the variables Age and Height between all stages: P3, P4 and P5 of maturation. The differences found in body mass occurred only between stages P3 and P5; P4 and P5. It was also observed that no significant differences were found for motor coordination between the maturation stages. The same occurred when the physical activity indices were compared CONCLUSION: There is no difference in the level of physical activity between stages 3, 4 and 5 of sexual maturation, nor does the maturational stage seem to influence the level of motor coordination of young schoolchildren.
