Introduction: Periodically, at the turn of August and September, the problem of overloading children with too heavy school backpacks is rising. Material and Method: Body posture studies were carried out in a group of 65 students aged 7 years, using the moiré projection method in 4 positions: 1st- in habitual posture, 2nd-in posture after 10 minutes of load, 3rd-in posture one minute after removing the load, 4th-in posture two minutes after removing the load. Physical fitness was measured with the modified Sekita test. Results: The values of body posture features were analyzed to determine the significance of differences between consecutive measurements and their relationship with the values of physical fitness features.
