[Subjects] Forty-six students between the ages of 8 and 14 years volunteered. [Method] The percentage of body weight (% BW) of each student's backpack was calculated and the students were separated into three groups based on the results: Group A (0-7% BW), Group B (7.01-14% BW) and Group C (14.01-21%BW). [Results] The use of the backpack increased the area of the CoP sway, displacement and mean speed of the CoP data in the antero-posterior and medial-lateral directions in Group C. [Conclusion] Therefore, observed responses in the body posture changes caused by the weight of the backpack were similar to those reported in other studies conducted with different methodos of investigation.1079-1082engBackpackBiomechanicsLoad carriagePostureStabilogramArtigo10.1589/jpts.24.1079Acesso aberto2-s2.0-848747372602-s2.0-84874737260.pdf
